This technology is characterized in that a phosphorescent member that emits accumulated external light is provided so that the attachment direction can be confirmed when the portable device is attached to the detachable member in the dark. As still another example, Patent Document 3 below describes a technique related to a detachable panel device provided in an information providing device. This technique has one feature in that the operation device can be attached to and detached from the display panel. Another feature is that the operating device has two different communication means.

<One Embodiment of the Present Invention>
Hereinafter, an embodiment of the present invention will be described. The present embodiment is characterized in a technique for selecting a still image to be displayed when switching to the still image display mode based on user preference information in a thin display device having a still image display mode. With this technology, even when the user uses the display device on a wall, it can be used as a part of the interior suitable for the user's living space, and a new usage style of the thin display device can be realized.

[Overall Structure of Display Device 100]
First, the overall structure of the display device 100 according to the present embodiment will be described with reference to FIGS. 1 and 2. 1 and 2 are explanatory diagrams illustrating the overall configuration of the display device 100 according to the present embodiment. In particular, FIG. 1 is an explanatory diagram showing the overall structure when the display device 100 is viewed obliquely from the front upper right. FIG. 2 is an explanatory diagram showing an overall structure when the display device 100 is viewed obliquely from the upper right of the back surface of the display device 100 and a detachment structure between the display unit 110 and the base unit 120.

  For example, as shown in FIG. 1, the display device 100 according to the present embodiment mainly includes a display unit 110 and a base unit 120.

  As shown in FIGS. 1 and 2, the display unit 110 mainly includes a display panel 1102, a peripheral unit 1104, a back unit 1108, a connection unit 1110, and a signal input / output terminal 1112. The Further, the base unit 120 mainly includes an arm 1202, a card reader 1204, a connection unit 1206, and an antenna 1208.

(Display panel 1102)
As the display panel 1102, for example, a thin panel such as an organic EL panel or a liquid crystal panel can be adopted. However, when used as a wall-mounted display, it is preferable to employ an organic EL panel.

  The organic EL panel is formed of a plurality of organic EL elements that are self-luminous light emitting elements. Therefore, the organic EL panel does not require a device such as a backlight, and can be formed thinner than the display panel having another light emitting mechanism. When an organic EL panel is adopted as the display panel 1102, it is said that the thickness of the display unit 110 can actually be suppressed to a thickness of about several mm (about 3 mm) or less. Therefore, the organic EL panel is lighter than a display panel that employs another light emitting mechanism.

(Arm 1202)
In the example of FIG. 1, the arm 1202 is provided at one location behind the base portion 120 and is erected upward from the base portion 120. Further, when the display device 100 is viewed from the front, the arm 1202 is provided on the right side of the center of the base unit 120 in the horizontal direction (horizontal direction) and on the right side of the center of the display unit 110 in the horizontal direction. It is connected.

  As described above, the display device 100 has, for example, a structure in which the arm 1202 is provided on either the left or right end side of the horizontal center of the display unit 110, and the display unit 110 is supported in a cantilever manner. Is done. The arm 1202 may be connected to the horizontal end of the display unit 110. Alternatively, a cantilever structure in which the upper end of the arm 1202 is connected to the vicinity of the center in the horizontal direction of the display unit 110 and the lower end is connected to the end of the base unit 120 may be employed. Further, the arm 1202 may have a structure (not shown) that is folded and stored in the base unit 120.

(Connections 1110, 1206)
Further, as shown in FIG. 2, the display unit 110 and the base unit 120 may have a structure that can be removed at the connection portions 1110 and 1206 as indicated by a reference symbol X. When the display unit 110 is removed in this way, for example, the display unit 110 receives image reception data and the like from the base unit 120 via wireless communication, and outputs the received image reception data and the like to the display panel 1102.

(About the weight of the display panel 1102)
Such a structure can be realized relatively easily by adopting, for example, a lightweight and thin organic EL panel for the display panel 1102. Of course, instead of the organic EL panel, a thin and lightweight display panel using another light emitting mechanism may be used. However, when a liquid crystal panel is adopted as the display panel 1102, the display unit 110 becomes thicker as much as the backlight is installed, and naturally the weight increases accordingly.

  For example, when used as a display for displaying TV images, this display has more backlights than those used for computers, etc., in order to achieve image quality that can withstand viewing of TV images. Is done. In addition, since an inverter for controlling the backlight is also installed in the liquid crystal display, the weight further increases.

  On the other hand, since the organic EL panel is formed of a self-luminous organic EL element, a driving member such as a backlight and an inverter associated therewith is not necessary. Therefore, the organic EL panel is formed to be lightweight mainly using a thin glass panel. As a result, by adopting an organic EL panel as the display panel 1102, a lightweight and thin display unit 110 can be realized relatively easily.

  Thus, when the display unit 110 is light and thin, the structure of the display device 100 supported only by the arm 1202 installed on one side is easily realized as shown in FIG. A usage mode in which the unit is detached from 1202 or folded and wall-mounted is easily realized.

(Effects of cantilever structure)
As shown in FIG. 1, when the arm 1202 is arranged from the lateral central portion of the display unit 110 toward the end, the display unit 110 is supported in a cantilevered manner. Therefore, the user who views the video while facing the display unit 110 can recognize only the display screen independently by removing the arm 1202 from the visual field. As a result, the user can receive an impression that the display unit 110 is floating on the base unit 120. Therefore, the structure in which the display unit 110 is supported in a cantilever manner can generate an effect that allows the user to gaze at only the display screen independently.

  Further, since it is not necessary to connect the base of the arm 1202 to the center of the base portion 120, the degree of freedom regarding the installation of the arm 1202 is improved. Therefore, it is possible to determine the installation position of the arm 1202 with respect to the base portion 120 in consideration of the internal structure of the base portion 120, the arrangement of the substrate, and the like. As a result, the degree of freedom in design increases. In this way, when the degree of freedom in design increases, it is possible to arrange the device members so as to increase the space utilization efficiency in consideration of the internal structure of the base portion 120, and therefore, the size of the display device 100 can be further reduced. Is possible. As a result, the weight of the display device 100 itself can be greatly reduced.

  In addition, since the arm 1202 is not installed at the center of the base portion 120, an effective space can be widened on the upper surface of the base portion 120. Therefore, for example, a display screen, operation buttons, LED indicators, a card reader 1204 for a non-contact IC card, and the like can be installed on the base unit 120.

(About the folding structure of the arm 1202)
By the way, the arm 1202 is rotatably installed so as to be inclined from the rear side of the base part 120 toward the back surface of the display part 110, and can be set at an angle vertical or horizontal with respect to the base part 120 ( (Not shown). When the inclination angle of the arm 1202 with respect to the vertical direction is set to about 45 ° to 60 °, the arm 1202 appears to be hidden behind the display unit 110 for the user facing the front of the display unit 110.

  Further, when the display unit 110 and the arm 1202 are folded so as to have a horizontal angle with respect to the base unit 120, the display device 100 has a plate-like form in which the display unit 110 and the base unit 120 are integrated. Become. Therefore, the user can easily carry or use the display device 100 by hanging it on the wall.

(About the wall surface setting of the display unit 110)
Further, when the display unit 110 and the base unit 120 are removed, the display unit 110 can be easily carried by the user. Therefore, for example, the user can use the display unit 110 by connecting to the other base unit 120 or by fixing the display unit 110 to the frame-type base unit 120 installed on the wall surface. The user can also use the display unit 110 by hanging it alone. In this case, the display unit 110 displays, for example, image reception data received from the base unit 120 via wireless communication.

  In this way, the user can enjoy the still image acquired by the broadcast video or the imaging device by moving the thin and light display unit 110 to various living spaces or activity points. At this time, if the display unit 110 becomes thinner and lighter, the display unit 110 is likely to be carried and the user's applications are expected to be greatly expanded. However, in order to allow the user to use the display unit 110 safely and stably in various situations, it is necessary to further devise the installation means.

  For example, when the display unit 110 is fixed to the base unit 120 installed on the wall surface, or when the display unit 110 is fixed to a hook provided on the wall surface, the display unit 110 is physically securely fixed so as not to fall. Need to be. When power is supplied from the base unit 120 installed on the wall surface, the display unit 110 needs to be electrically connected to the base unit 120 reliably. Further, when a video signal or the like is received from the base unit 120 by wire, or when audio output or the like is performed using a function (for example, a communication function or an audio output function) of the base unit 120, the display unit 110 is The signal path to the unit 120 needs to be securely connected.

  Therefore, the display unit 110 according to the present embodiment detects, for example, that the signal input / output terminal 1112 is securely connected when connected to the base unit 120 installed on the wall surface, and notifies the user. It has a means to notify. In addition, the display unit 110 includes a unit that detects that the display unit 110 is physically fixed to the wall surface and notifies the user. Further, the display unit 110 has means for detecting the power supply state and notifying the user when receiving power supply from the base unit 120 or the like installed on the wall surface. These means will be described in detail later.

(Base part 120)
Here, the base part 120 will be described in more detail. The base unit 120 may incorporate various terminals such as satellite broadcast (BS, CS), digital terrestrial broadcast tuner, LAN, HDMI, USB, and the like as attached components. Further, as shown in FIG. 2, the base unit 120 may be provided with an antenna 1208 for receiving terrestrial digital broadcasting. The antenna 1208 may be, for example, a rod antenna or a patch antenna. Furthermore, the base unit 120 may incorporate a speaker box, operation buttons, and the like. Note that these attached configurations may be built in the back surface 1108 of the display unit 110.

  Furthermore, the base part 120 has an exhaust heat structure for efficiently exhausting heat to the outside. The base unit 120 includes a signal processing circuit that drives and controls the display unit 110. This signal processing circuit is mainly composed of a first circuit board (O board), a second circuit board (B-CAS board), a cooling fan, and a heat radiating plate (heat spreader).

  The heat radiating plate is formed according to the shape of the base portion 120 (for example, in a rectangular shape) and is formed by a press-formed metal plate. Further, the heat radiating plate is formed so as to extend to a region where the electronic component is not mounted inside the base portion 120. Further, the heat sink is provided with a plurality of irregularities corresponding to the positions of the electronic components mounted on the first and second circuit boards. The unevenness is formed so as to be in contact with electronic components mounted on the first and second circuit boards. The heat radiating plate is formed so as to be in direct contact with each electronic component or indirectly through a heat conductive sheet (heat radiating sheet) such as silicon rubber.

  In addition, a cooling fan may be installed on the heat sink. In this case, the base portion 120 is provided with a suction port for sucking outside air and a discharge port for discharging the sucked air in a portion located below the cooling fan. For this reason, the air sucked from the suction port is provided on the rear surface of the base portion 120 in order to absorb the heat of the first and second circuit boards and cool them, and then discharge the absorbed heat to the outside. It is discharged from the discharge port to the outside. In addition, the heat pipe for discharging | emitting the heat of a heat sink efficiently to the exterior may be provided.

  By using the exhaust heat structure, the inside of the base portion 120 can be efficiently cooled. However, when the first and second circuit boards are built in the display unit 110, the display panel 1102 is provided with the heat exhaust structure as described above, thereby extending the life of the display panel 1102 or improving the image quality due to heat generation. A decrease and a decrease in luminous efficiency can be suppressed. This effect is prominent when the wall is used for a long time.

[Connection Notification Method for Display Unit 110]
Here, the connection notification method of the display unit 110 according to the present embodiment will be described with reference to FIGS. 3 and 4. 3 and 4 are explanatory diagrams illustrating a connection notification method of the display unit 110 according to the present embodiment.

(Connection notification by the base unit 220)
First, referring to FIG. FIG. 3 shows the display unit 110 and the base unit 220 installed on the wall surface. The base portion 220 may be the base portion 120 described above. Moreover, the base part 220 may be provided with a part or all of the functions of the base part 120 described above. The base portion 220 may be a fixed member such as a simple frame.

  As shown in FIG. 3, the base unit 220 mainly includes a peripheral unit 2202, a signal input / output terminal 2204, and an audio output unit 2206. In the example of FIG. 3, the outer peripheral part of the display unit 110 is fitted and fixed to the inner peripheral part of the peripheral part 2202 that forms the base part 220. At this time, the signal input / output terminal 1112 of the display unit 110 and the signal input / output terminal 2204 of the base unit 220 are connected.

  Although not explicitly shown in the drawing, the display unit 110 or the base unit 220 may be provided with, for example, a fitting detection sensor FS for detecting a state in which the display unit 110 and the base unit 220 are fitted. Good. The display unit 110 or the base unit 220 may be provided with a power supply detection sensor PS for detecting the power supply state when power is supplied from the base unit 220 to the display unit 110, for example. Furthermore, the display unit 110 or the base unit 220 may be provided with a signal detection sensor SS that detects signals input / output via the signal input / output terminals 1112, 2204, for example.

  For example, when the display unit 110 and the base unit 220 are connected, the display unit 110 inputs an audio output signal to the base unit 220 via the signal input / output terminal 1112. When the signal input / output terminals 1112 and 2204 are securely connected, the audio output signal input from the display unit 110 is input to the base unit 220 and the audio is output from the audio output unit 2206 of the base unit 220. As a result, the user can confirm that the signal path between the display unit 110 and the base unit 220 is securely connected. However, the display unit 110 detects the connection state with the base unit 220 based on output signals transmitted from the fitting detection sensor FS, the power feeding detection sensor PS, and the signal detection sensor SS, for example.

  For example, when the timing at which power supply is started from the base unit 220 to the display unit 110 is important, the user performs voice at the timing at which the output signal of the power supply detection sensor PS and the output signal of the signal detection sensor SS are received. The output signal can be set to be transmitted. Similarly, when it is important to know the state in which the display unit 110 is securely fixed to the base unit 220, the timing at which the user receives the output signal of the fitting detection sensor FS and the output signal of the signal detection sensor SS. Can be set so that a voice output signal is transmitted. Of course, the user can also set the audio output signal to be transmitted at the timing when only the output signal of the signal detection sensor SS is received.

  As described above, when the display unit 110 and the base unit 220 are connected, an audio output signal is transmitted from the display unit 110, and the audio is output by the audio output unit 2206 provided in the base unit 220. The user can be notified that at least the signal input / output terminals 1112 and 2204 are securely connected.

  Further, as an application example of the above technique, a method of wirelessly transmitting the signal path of the audio output signal can be considered. In the case of this method, the display unit 110 transmits an audio output signal to the base unit 220 at a timing when the output signal of the power feeding detection sensor PS or the output signal of the fitting detection sensor FS is received. Then, the base unit 220 outputs sound from the sound output unit 2206 according to the received sound output signal. In this case, it is possible to output sound according to the state of the power feeding path or the fitting state regardless of the connection state of the signal path. Note that this wireless method is realized by using various communication forms such as infrared communication, visible light communication, and RF communication.

(Connection notification by display unit 110)
Reference is now made to FIG. FIG. 4 shows the display unit 110 and the base unit 220 installed on the wall surface. The base portion 220 may be the base portion 120 described above. Moreover, the base part 220 may be provided with a part or all of the functions of the base part 120 described above. The base portion 220 may be a fixed member such as a simple frame.

  As shown in FIG. 4, the display unit 110 mainly includes a display panel 1102, a peripheral unit 1104, a signal input / output terminal 1112 (see FIG. 2), and an audio output unit 1114. In the example of FIG. 4, the outer peripheral part of the display unit 110 is fitted and fixed to the inner peripheral part of the peripheral part 2202 that forms the base part 220. At this time, the signal input / output terminal 1112 of the display unit 110 and the signal input / output terminal 2204 of the base unit 220 are connected. The difference between FIG. 3 and FIG. 3 is mainly whether the audio output unit is provided in the display unit 110 (audio output unit 1114) or the base unit 220 (audio output unit 2206). ).

(Case 1)
For example, when the display unit 110 and the base unit 220 are connected, the display unit 110 transmits an audio output signal, and outputs audio from the audio output unit 1114 based on the audio output signal (case 1). In this case, the display unit 110 transmits an audio output signal according to the output signal of the signal detection sensor SS, the fitting detection sensor FS, or the output signal of the power supply detection sensor PS. However, the output signal of the signal detection sensor SS is output according to a predetermined signal transmitted from the display unit 110 or the base unit 220 when the display unit 110 and the base unit 220 are connected. For example, when the signal path is a non-contact communication system, a predetermined signal is output in response to a polling command transmitted from one of the signal input / output terminals 1112, 2204.

(Case 2)
As another example, when the display unit 110 and the base unit 220 are connected, the base unit 220 inputs an audio output signal to the display unit 110 via the signal input / output terminal 2204 (case 2). When the signal input / output terminals 1112 and 2204 are securely connected, the audio output signal input from the base unit 220 is input to the display unit 110 and audio is output from the audio output unit 1114 of the display unit 110. As a result, the user can confirm that the signal path between the display unit 110 and the base unit 220 is securely connected.

  In addition, the base part 220 may detect the connection state between the display part 110 based on the output signal transmitted, for example from said fitting detection sensor FS, electric power feeding detection sensor PS, and signal detection sensor SS. . Alternatively, the base unit 220 transmits an audio output signal according to a predetermined signal transmitted from the display unit 110 based on output signals transmitted from the fitting detection sensor FS, the power supply detection sensor PS, and the signal detection sensor SS. May be.

  As described above, when the display unit 110 and the base unit 220 are connected, an audio output signal is transmitted from the display unit 110 or the base unit 220, and audio is output by the audio output unit 1114 provided in the display unit 110. By doing so, it is possible to notify the user that at least the signal input / output terminals 1112 and 2204 are securely connected.

  The connection notification method using the display unit 110 and the base unit 220 has been described above. The connection notification method according to the present embodiment is not limited to the above example. For example, it is possible to provide sound output means on both the display unit 110 and the base unit 220.

  Further, the signal detection sensor SS may individually detect the input / output state of the audio signal and the input / output state of the video signal as the signal state, and whether the S / N ratio of the input signal is a predetermined value or more. You may detect whether or not. Furthermore, the fitting detection sensor FS may detect whether or not the hook (not shown) of the base portion 220 and the hook hole (not shown) of the display portion 110 are in the locked state as the fitting state. It may be detected whether or not the pair of connecting members are physically connected. The display unit 110 and the base unit 220 may use a magnetic coupling member as a mechanism for physically fixing. In this case, instead of the fitting detection sensor FS, for example, a coupling strength sensor MS for detecting the coupling strength between the display unit 110 and the base unit 220 is used. Thus, various modifications are possible.

[Modification of Display Unit 110]
Next, a modified example of the display unit 110 according to the present embodiment will be described with reference to FIGS. 5, 6, and 7. 5, 6, and 7 are explanatory diagrams illustrating modifications of the display unit 110 according to the present embodiment.

First, referring to FIG. FIG. 5 is an explanatory view showing a modification of the outer frame of the display unit 110 and the installation member. As shown in FIG. 5, the display unit 110 according to this modification mainly includes an outer frame portion 1116 and an installation member 1118 in addition to the display panel 1102 and the peripheral portion 1104.

  The outer frame portion 1116 is configured by a transparent member having a rigidity equal to or greater than a predetermined value, or a translucent member. The outer frame portion 1116 is, for example, an amorphous solid material such as glass having a light transmittance of a predetermined value or more, a plastic material such as polycarbonate, an amorphous synthetic resin material such as an acrylic resin, or other glassy substances. It is formed by. In addition, the outer frame portion 1116 may be decorated such that light is reflected, refracted, scattered, or the like. Furthermore, the outer frame portion 1116 may be formed by combining a plurality of materials having different refractive indexes and the like.

  One or more installation members 1118 are formed on the outer frame portion 1116. In the example of FIG. 5, six installation members 1118 are formed. The installation member 1118 is, for example, a hook hole or the like that is fitted to an installation member such as a hook provided on the wall surface or the base portion 220. Conversely, the installation member 1118 may be a protruding member that fits into a wall surface or a hook hole provided in the base portion 220. Further, the installation member 1118 may be a metal member or a magnetic coupling member for joining and fixing to a magnetic coupling member or a metal member provided on the wall surface or the base portion 220. As described above, the installation member 1118 can be realized in various forms. Therefore, the shape of the installation member 1118 may be a rectangle as shown in FIG. 5, but may be an arbitrary shape such as a substantially circular shape, a substantially polygonal shape, or a star shape or a human shape, for example.

  As described above, by forming the outer frame portion 1116 with a transparent or translucent member, the size of the frame region that is enlarged to provide the installation member 1118 is not conscious, and the peripheral portion 1104 Design can be improved by emphasizing the contrast. In order to enhance the effect, it is preferable to make the peripheral portion 1104 an opaque color. The installation member 1118 may be provided with a fitting detection sensor FS or a coupling strength sensor MS.

(Reinforcing member 1120)
Reference is now made to FIG. FIG. 6 is an explanatory view showing a modified example related to the reinforcing member provided in the outer frame portion 1116. As shown in FIG. 6, the display unit 110 according to this modification is mainly configured by a reinforcing member 1120 in addition to a display panel 1102, a peripheral part 1104, an outer frame part 1116, and an installation member 1118. .

  The reinforcing member 1120 is a member for mainly increasing the strength of the installation member 1118 or the peripheral portion of the installation member 1118. Therefore, the reinforcing member 1120 is formed of a material having higher rigidity than the outer frame portion 1116. The reinforcing member 1120 is made of, for example, a metal material or a high-strength resin material. Further, the reinforcing member 1120 may be formed of any one of a transparent member, a translucent member, and an opaque member. Furthermore, the reinforcing member 1120 may be formed of a material that reflects or scatters light on the surface or inside, or a part or all of the surface may be covered with a material that reflects or scatters light.

  As shown in FIG. 5, the reinforcing member 1120 is formed around the installation member 1118. The reinforcing member 1120 preferably has a shape that matches the shape of the installation member 1118. Therefore, the reinforcing member 1120 may be a rectangle as shown in FIG. 6, or may be a substantially circular shape, a substantially polygonal shape, or the like. Further, since the reinforcing member 1120 only needs to reinforce the installation member 1118 or the periphery thereof, it does not necessarily have to be connected to the outer periphery of the installation member 1118. A plurality of reinforcing members 1120 may be provided for one installation member 1118. Further, the reinforcing member 1120 may be installed in a region where the installation member 1118 is not formed in order to increase the strength of the outer frame portion 1116 as a whole. The reinforcing member 1120 may be provided with a fitting detection sensor FS or a coupling strength sensor MS.

(Light emitting unit 1122)
Reference is now made to FIG. FIG. 7 is an explanatory diagram illustrating a modification example of the light emitting unit provided in the peripheral portion 1104. As shown in FIG. 7, the display unit 110 according to this modification mainly includes a light emitting unit in addition to a display panel 1102, a peripheral unit 1104, an outer frame unit 1116, an installation member 1118, and a reinforcing member 1120. 1122.

  The light emitting unit 1122 is a unit that emits light mainly toward the outer frame portion 1116. That is, the light emitting unit 1122 emits light in the direction from the display panel 1102 to the outer frame unit 1116. However, the light emitting unit 1122 emits light having a certain degree of spread into and out of the outer frame 1116. Therefore, the light emitted from the light emitting unit 1122 diffuses to a finite region inside the outer frame portion 1116, and the entire outer frame portion 1116 appears to emit light.

  For example, when a material that diffuses light is used for the outer frame portion 1116, the outer frame portion 1116 appears to shine brightly. Further, when a material that reflects or scatters light is used for the reinforcing member 1120, the light diffusion state in the outer frame portion 1116 becomes more complicated, and the reinforcing member 1120 shines stronger or weakly, so that accentuates lightness and color. Can be added. As a result, the effect that the design of the entire display unit 110 is greatly improved can be obtained.

  In the above, the modification of the display part 110 which concerns on this embodiment was demonstrated. It is possible to combine some or all of the above-described modified examples in various ways, and such combinations also belong to the technical scope of the present embodiment. The peripheral portion 1104, the outer frame portion 1116, the reinforcing member 1120 and the like can be arbitrarily set in color tone, color, etc., and the chromaticity of light emitted from the light emitting portion 1122 can be freely set by the user. Also good. Further, the light emitting unit 1122 may be installed at an arbitrary position inside or outside the outer frame portion 1116 in addition to being installed at an arbitrary position inside or outside the peripheral portion 1104.

[Functional configuration of display device 100]
Next, the functional configuration of the display device 100 according to the present embodiment will be described with reference to FIG. FIG. 8 is an explanatory diagram illustrating a functional configuration of the display device 100 according to the present embodiment. As shown in FIG. 8, the display device 100 mainly includes a display unit 110 and base units 120 and 220. Therefore, the functional configuration of each of the display unit 110 and the base units 120 and 220 will be described.

(Functional configuration of display unit 110)
As shown in FIG. 8, the display unit 110 mainly includes a video output unit 1150, a connection management unit 1170, a photo sensor 1142, a gyro sensor 1144, a power supply unit 1146, and a communication unit 1148. .

(Video output unit 1150)
The video output unit 1150 mainly includes a pixel unit 1152, scanning circuits 1154 and 1156, and a drive control unit 1158.

  The pixel portion 1152 includes a pixel array in which a plurality of pixels are formed in a matrix. Each pixel is formed by a light emitting element that emits light of any of the three primary colors (red, blue, green), and is disposed at the intersection of signal lines extending from the scanning circuits 1154 and 1156. The scanning circuits 1154 and 1156 apply a power signal to each signal line in accordance with a control signal input from the drive control unit 1158. Each pixel emits light according to the power signal input from each signal line. For example, in the case of an organic EL panel, electrons are injected into the element according to a signal on one signal line, and holes are injected into the element according to a signal on another signal line.

  Here, a specific apparatus configuration of the video output unit 1150 will be described in detail with reference to FIG. FIG. 9 is an explanatory diagram showing a specific device configuration of the video output unit 1150 according to the present embodiment. The video output unit 1150 exemplified here is an active matrix type display means.

  As shown in FIG. 9, the video output unit 1150 is mainly composed of a pixel array 1192 and a peripheral circuit unit. Further, the peripheral circuit unit is constituted by, for example, a horizontal selector 1194, a write scanner 1196, and a drive scanner 1198.

  The pixel array 1192 is formed at each portion where the row-shaped scanning lines WS and the column-shaped signal lines SL intersect, and is composed of a plurality of pixels R, G, and B arranged in a matrix. Note that the pixel array 1192 exemplified here is formed of pixels of three primary colors (R, G, B) necessary for color display. However, the type of pixel according to the present embodiment is not limited to this. Each pixel is formed by a pixel circuit 1190. Further, the signal line SL is driven by a horizontal selector 1194. The horizontal selector 1194 is realized by a driver IC (Integrated Circuit), and plays a role of supplying a video signal to the signal line SL.

  On the other hand, the scanning line WS is scanned by the write scanner 1196. As shown in FIG. 9, a plurality of scanning lines WS are provided, and a second scanning line DS is wired in parallel with the first scanning line WS. The second scanning line DS is scanned by the drive scanner 1198. The light scanner 1196 and the drive scanner 1198 constitute a scanner unit, and sequentially scan pixels in units of rows for each horizontal scanning period.

  The pixel circuit 1190 samples the video signal from the signal line SL when selected by the first scanning line WS. Furthermore, the pixel circuit 1190 drives the light emitting elements included in the pixel circuit 1190 according to the sampled video signal when selected by the second scanning line DS. In addition, the pixel circuit 1190 performs a predetermined correction process when controlled by the first scanning line WS and the second scanning line DS within the horizontal scanning period.

  The pixel array 1192 is formed on an insulating substrate such as glass. Therefore, the pixel array 1192 formed on the insulating substrate forms a flat panel. The pixel circuit 1190 is formed by a transistor circuit such as an amorphous silicon thin film transistor or a low temperature polysilicon thin film transistor. In the case of an amorphous silicon thin film transistor, the scanner unit is formed of, for example, TAB other than the panel, and has a structure connected to the flat panel using a flexible cable. Similarly, the signal portion for driving the signal line is formed by, for example, an external driver IC, and has a structure connected to the flat panel using a flexible cable.

(Connection Manager 1170)
Refer to FIG. 8 again. The connection management unit 1170 is a means for managing the connection state between the display unit 110 and the base units 120 and 220. For example, the connection management unit 1170 transmits an audio output signal to the communication unit 1148 when the display unit 110 and the base units 120 and 220 are electrically connected. Similarly, the connection management unit 1170 transmits an audio output signal to the communication unit 1148 when the display unit 110 and the base units 120 and 220 are physically connected.

  Further, the connection management unit 1170 may perform power saving control so that the power consumption unit 1146 reduces power consumption when the display unit 110 and the base units 120 and 220 are detached. This power saving control is, for example, a method of reducing the amount of power consumed by the display unit 110 by controlling the power supply amount to the video output unit 1150 to be reduced or stopped. Conversely, the connection management unit 1170 can also control the power supply unit 1146 to restore the power consumption when the display unit 110 and the base units 120 and 220 are connected.

  Here, the functional configuration of the connection management unit 1170 will be described in more detail with reference to FIG. FIG. 10 is an explanatory diagram showing the functional configuration of the connection management unit 1170 according to the present embodiment in more detail.

  As shown in FIG. 10, the connection management unit 1170 mainly includes a connection detection unit 1172, a power saving control unit 1174, and an audio signal transmission unit 1176. The connection detection unit 1172 includes a physical connection detection unit 1182 and an electrical connection detection unit 1184.

(Physical connection detection unit 1182)
For example, when the physical connection state between the display unit 110 and the base units 120 and 220 is detected by the fitting detection sensor FS (or the coupling strength sensor MS), the physical connection detection unit 1182 detects the fitting detection sensor. A power restoration control signal and an audio output signal are transmitted according to the output signal of FS (or coupling strength sensor MS). This power restoration control signal is a signal for restoring from the power saving state to the original power supply state, and is input to the power saving control unit 1174. The audio output signal is input to the audio signal transmission unit 1176.

  Similarly, when the display unit 110 and the base units 120 and 220 are physically separated, the physical connection detection unit 1182 controls power saving according to the output signal of the fitting detection sensor FS (or the coupling strength sensor MS). Send a signal. This power saving control signal is a signal for controlling the display unit 110 to the power saving state, and is input to the power saving control unit 1174.

(Electrical connection detection unit 1184)
For example, when the electrical connection state between the display unit 110 and the base units 120 and 220 is detected by the signal detection sensor SS or the power feeding detection sensor PS, the electrical connection detection unit 1184 outputs the signal detection sensor SS. A power restoration control signal and an audio output signal are transmitted according to the signal or the output signal of the power feeding detection sensor PS. In addition, when the display unit 110 and the base units 120 and 220 are electrically separated, the electrical connection detection unit 1184 controls power saving according to the output signal of the signal detection sensor SS or the output signal of the power feed detection sensor PS. Send a signal.

  For convenience of explanation, the expression “electrical” is used. However, when a power feeding mechanism or a signal transmission mechanism using electromagnetic induction is used, it is read as “electromagnetic” or “magnetic”. I want you. In addition, when power is supplied or transmitted using light, please read the expression “optical”. Of course, these modifications belong to the technical scope of the present embodiment.

(Power saving control unit 1174, audio signal transmission unit 1176)
The power saving control unit 1174 executes power control of the power supply unit 1146 in accordance with the power saving control signal received from the connection detection unit 1172 or the power restoration control signal. For example, when receiving the power saving control signal, the power saving control unit 1174 reduces or stops the amount of power supplied from the power supply unit 1146 to the video output unit 1150. Conversely, when receiving the power restoration control signal, the power saving control unit 1174 causes the video output unit 1150 whose power supply amount has been reduced or stopped to supply the power amount before the power saving control. If power saving control is performed for components other than the video output unit 1150, the power supply amount is restored for other components as well.

  The audio signal transmission unit 1176 causes the audio output unit 1114 provided in the display unit 110 to output audio in accordance with the audio output signal received from the connection detection unit 1172 (see FIG. 4). Or the audio | voice signal transmission part 1176 transmits an audio | voice output signal to the base parts 120 and 220 by the communication part 1148 according to the audio | voice output signal received from the connection detection part 1172 (refer FIG. 3). With these functions, the user can confirm the sound output from either or both of the display unit 110 and the base units 120 and 220, so that the physical or between the display unit 110 and the base units 120 and 220 can be The electrical connection state can be confirmed.

(Photo sensor 1142, power supply unit 1146)
Refer to FIG. 8 again. The photosensor 1142 is a light receiving unit that detects light emitted from the outside. For example, the photo sensor 1142 receives infrared rays transmitted from a remote controller (hereinafter referred to as a remote controller), and transmits the control processing content designated by the remote controller operation to the drive control unit 1158. As another example, the photo sensor 1142 detects the amount of illumination light at the place where the display unit 110 is installed, and notifies the drive control unit 1158 to adjust the luminance and contrast of the video output by the video output unit 1150. .

  The power supply unit 1146 is means for supplying power to each component of the display unit 110. The power supply unit 1146 can adjust the amount of power supplied to the video output unit 1150 or other components according to the power saving control signal or the power restoration control signal received from the connection management unit 1170. For example, the power supply unit 1146 can reduce the amount of power supplied to the video output unit 1150 and the communication unit 1148 or stop the power supply itself.

(Gyro sensor 1144)
The gyro sensor 1144 is means for detecting the installation direction of the display unit 110. For example, as shown in FIG. 11A, when the display unit 110 is installed vertically, the gyro sensor 1144 detects that the display unit 110 is installed vertically and indicates its directionality (vertical). Information is input to the drive control unit 1158. Then, the drive control unit 1158 adjusts the output direction so that the directionality of the video output to the pixel unit 1152 matches the directionality (vertical) of the display unit 110. Similarly, when the display unit 110 is installed horizontally (FIG. 11B) or rotated from a vertical installation to a horizontal installation, the gyro sensor 1144 indicates that the display unit 110 is installed horizontally. Information indicating the directionality (lateral) is input to the drive control unit 1158. Then, the drive control unit 1158 adjusts the output direction so that the directionality of the video output to the pixel unit 1152 matches the directionality (horizontal) of the display unit 110.

(Communication unit 1148)
The communication unit 1148 is a means for transmitting and receiving information to and from the base units 120 and 220. For example, the communication unit 1148 receives the video data acquired by the base units 120 and 220 and inputs the video data to the drive control unit 1158. Then, the drive control unit 1158 outputs the video data to the pixel unit 1152. In addition, the communication unit 1148 transmits the audio output signal output from the connection management unit 1170 to the base units 120 and 220. Then, the base units 120 and 220 can output sound according to the received sound output signal.

  The communication unit 1148 is, for example, wireless communication means such as infrared communication, RF communication, non-contact communication (magnetic coupling communication), or visible light communication, or a wired communication means.

  For example, when the communication unit 1148 is a communication means for infrared communication or visible light communication, the communicable distance between the display unit 110 and the base units 120 and 220 is predetermined due to the short attenuation distance and the non-transparent wall surface. Limited within range. Therefore, the user can easily select the base units 120 and 220 for providing video data to the display unit 110. For example, when the user wants to enjoy the contents of the base units 120 and 220 in the room where the user is present, the desired base units 120 and 220 are provided without any special setting by the user.

  On the other hand, when the communication unit 1148 is an RF communication means, since the attenuation distance is long and the wall surface is permeable, the base units 120 and 220 installed further away can be selected. For example, when the display unit 110 is taken out in a place where the base units 120 and 220 are difficult to install such as in a bathroom or outdoors, the user can easily enjoy the contents of the base units 120 and 220 installed in the living room. Become.

  Further, when the communication unit 1148 is a communication means for non-contact communication, it is provided by the mobile phone, the information processing apparatus, etc. by simply pointing the communication unit 1148 to a mobile phone, an information processing apparatus, etc. with a built-in non-contact communication function. Possible content can be displayed on the display unit 110. In addition, a usage form in which information recorded on a non-contact IC card or the like is displayed using the display unit 110 is also conceivable. In that case, the communication unit 1148 is equipped with a reader / writer function of a non-contact IC card. In addition, since non-contact communication is a magnetic coupling type communication technology using an electromagnetic induction phenomenon, it is possible to supply power from the base units 120 and 220 to the display unit 110 using this electromagnetic induction. In that case, the communication unit 1148 also forms a power feeding path.

  When the communication unit 1148 is a wired communication unit, the signal cannot be transmitted unless the base units 120 and 220 are reliably contacted and a signal path is established. Therefore, if transmission / reception of a signal is confirmed via the communication unit 1148, it can be confirmed that the signal path is in a connected state. In this case, the communication unit 1148 forms part of the signal detection sensor SS.

  Heretofore, the functional configuration of the display unit 110 according to the present embodiment has been described. Next, the functional configuration of the base units 120 and 220 will be described.

(Functional configuration of base units 120 and 220)

  The audio output unit 1242 is a unit that outputs audio in accordance with an audio output signal received from the display unit 110 via the communication unit 1244. That is, it corresponds to the audio output unit 2206. Similar to the communication unit 1148, the communication unit 1244 is a wired or wireless communication unit. The communication unit 1244 transmits video data, audio data, and the like to the display unit 110. In addition, the communication unit 1244 receives an audio output signal from the display unit 110 and inputs the audio output signal to the audio output unit 1242.

  The imaging unit 1246 is a unit that optically captures a subject and generates still image data or moving image data. The call function module 1248 is means for inputting / outputting voice or data via a wired or wireless telephone line. The call function module 1248 may be removable. For example, the call function module 1248 can be realized by connecting a call / communication device such as a mobile phone or a smart phone. It is also possible to provide a videophone function in combination with the imaging unit 1246.

  The external device connection interface 1250 is an interface for connecting an external device to the base units 120 and 220. For example, the external device connection interface 1250 includes, as external devices, information processing devices such as personal computers, portable terminals such as smartphones and mobile phones, external hard disk drives, printers, facsimiles, image scanners, optical disk drives, keyboards, An input device such as a mouse, an external connection speaker, a game machine, a portable music player, a portable video player, a one-segment tuner, or various information appliances are connected. The external device connection interface 1250 may be an interface that complies with standards such as IEEE 1394, USB, SCSI, RS-232C, PCMCIA, and the like.

  The broadcast reception interface 1252 is means for receiving distribution data such as terrestrial digital broadcast, terrestrial analog broadcast, satellite broadcast, cable television broadcast, and radio broadcast. The broadcast receiving interface 1252 may receive program information of terrestrial digital broadcasting. The external communication interface 1254 is a wired or wireless communication means for receiving information from a narrow area network such as a LAN or a wide area network such as the Internet. For example, the external communication interface 1254 can receive EPG information of a broadcast program via a wide area network, or can receive a broadcast program distributed via the Internet.

  The removable media interface 1256 is a means for connecting a removable medium in which various data are recorded, and for recording data or reading data. For example, a semiconductor memory device such as a memory stick, an SD card, or a USB memory, a small hard disk drive, or the like is connected to the removable media interface 1256 as a removable media. The storage unit 1258 is a storage unit that records video or audio data output from the signal processing unit 1270. The storage unit 1258 includes a storage device such as a magnetic storage device, an optical storage device, a magneto-optical storage device, or a semiconductor storage device.

(Signal processing unit 1270)
The signal processing unit 1270 is a unit that processes signals such as video and audio input from the various interfaces and outputs data that can be reproduced by the display unit 110. Further, the signal processing unit 1270 may record part or all of the output data in the storage unit 1258. Furthermore, the signal processing unit 1270 can transmit output data to the display unit 110 via the communication unit 1244. Hereinafter, a specific functional configuration of the signal processing unit 1270 will be described in more detail.

  As shown in FIG. 12, the signal processing unit 1270 mainly includes a plurality of receiving circuits 270 and 274, a plurality of demultiplexers 272 and 278, a descrambling unit 276, a data processing unit 282, and video processing. A unit 284, an audio processing unit 280, an OSD (On Screen Display) circuit 286, a synthesis circuit 288, and a controller 290 are configured.

  The signal processing unit 1270 is provided with two systems of receiving circuits 270 and 274 and two demultiplexers 272 and 278 corresponding to the receiving circuits 270 and 274, respectively. The receiving circuit 270 is, for example, a dedicated circuit for receiving an additional information signal transmitted through a predetermined channel. On the other hand, the receiving circuit 274 is a dedicated circuit for receiving a program broadcast signal transmitted through a predetermined channel, for example.

  The signal processing unit 1270 can receive the additional information signal via the receiving circuit 270 when the power is on. Similarly, the signal processing unit 1270 can receive a program broadcast signal via the receiving circuit 274. Therefore, the signal processing unit 1270 can receive a desired video signal, audio signal, and data signal, decode these signals, and output them.

  The controller 290 is a device that controls each component included in the signal processing unit 1270. The controller 290 is realized by, for example, a CPU 292, a ROM 294, a RAM 296, an EEPROM (Electrically Erasable Programmable ROM) 298, a DRAM (Dynamic RAM) 300, and a bus 302. That is, the CPU 292, ROM 294, RAM 296, EEPROM 298, and DRAM 300 are connected through the bus 302 to form a controller 290. It can be said that the controller 290 has a functional configuration similar to, for example, an information processing apparatus such as a personal computer.

  For example, the signal processing unit 1270 can store in the EEPROM 298 broadcast information such as a channel frequency and a program ID of a program broadcast signal received immediately after the power is turned on and immediately before the power is turned off. . In that case, when the signal processing unit 1270 is turned on, the controller 290 reads the broadcast information of the program broadcast signal received until immediately before the power supply was cut off from the EEPROM 298, and selects the channel for selecting the channel again. Output a control signal.

  This channel selection control signal is input to the demultiplexer 278 via the tuner 2742 of the receiving circuit 274. The tuner 2742 receives a program broadcast signal having a channel frequency indicated by the channel selection control signal input by the controller 290. Then, tuner 2742 inputs the received program broadcast signal to demodulation unit 2744. The demodulator 2744 demodulates the input program broadcast signal to generate a transport stream signal. The demodulator 2744 demodulates, for example, a program broadcast signal modulated with a 64QAM modulation method and multiplicity.

  This transport stream signal is input to error correction section 2746. The error correction unit 2746 performs error correction on the input transport stream signal and inputs it to the descrambling unit 276. For example, the error correction unit 2746 can perform error correction on a transport stream signal encoded by a Reed-Solomon code. Based on the information acquired from the controller 290, the descrambling unit 276 cancels the scramble applied to the input error-corrected transport stream signal and reproduces the program broadcast signal. Then, descrambling section 276 inputs the program broadcast signal after descrambling to demultiplexer 278.

  The demultiplexer 278 extracts broadcast program information (contents) according to the selection control signal acquired from the controller 297, and inputs the broadcast program information (contents) to the data processing unit 282, the video processing unit 284, or the audio processing unit 280 according to the type. . The data processing unit 282 generates a video signal for displaying characters or images from the input data and inputs the video signal to the synthesis circuit 288. The video processing unit 284 generates a video signal for displaying a video or an image from the input data and inputs the video signal to the synthesis circuit 288.

  A video signal is also input to the combining circuit 288 from the OSD circuit 286. The OSD circuit 286 generates a video signal for displaying, for example, an electronic program guide table and various guidance messages under the control of the controller 290 and inputs the video signal to the synthesis circuit 288. The combining circuit 288 combines the video signals input from the data processing unit 282, the video processing unit 284, and the OSD circuit 286, and outputs the combined video signal. Also, the audio processing unit 280 generates and outputs an audio signal from the input data.

  On the other hand, the controller 290 specifies the channel frequency based on the additional information signal multiplexed on the selected channel signal. Then, the controller 290 inputs a tuning control signal indicating the specified channel frequency to the tuner 2702 of the receiving circuit 270. The tuner 2702 receives the additional information signal based on the channel selection control signal input from the controller 297 and inputs it to the demodulation unit 2704. Demodulation section 2704 demodulates the input additional information signal and inputs it to error correction section 2706. Error correction section 2706 performs error correction on the additional information signal, and inputs the additional information signal after error correction to demultiplexer 272.

  The demultiplexer 272 extracts necessary additional information from the input additional information signal in accordance with control by the controller 290, and inputs the additional information to the controller 290. The controller 290 temporarily stores the additional information extracted by the demultiplexer 272 in the DRAM 300. Then, the controller 290 provides an additional information service such as an electronic program guide to the user terminal device based on the additional information. In addition, when receiving a broadcast program designation from the user, the controller 290 controls the tuner 2702 of the receiving circuit 270 so that a channel corresponding to the program is selected. Further, the controller 290 controls the demultiplexer 272 to extract data corresponding to the designated broadcast program.
