There is known a structure in which a support portion that rotatably supports the display panel is provided and the display panel is supported at two positions on both ends in the width direction of the display panel.

  Also, in a liquid crystal display panel or the like in a desktop personal computer, a support arm is erected upward from the main body of the liquid crystal display panel placed on a desktop or the like, and the central portion in the width direction of the liquid crystal display panel is It is generally done in support.

JP-A-11-102235

  However, since the conventional display device has a structure that supports the center or both ends in the width direction of the display panel, when the user visually recognizes the display panel, the display device is connected to the display panel from the main body through the support. Inevitably comes into view. For this reason, for the user, the display panel support structure from the display panel to the main body through the support unit enters the field of view, although the user originally wants to focus only on the display screen. For this reason, an extra structure enters the user's field of view, and the user cannot pay attention to only the display screen.

  In addition, if the display panel support section is provided at the center or both ends of the display panel, the degree of freedom of the layout of the support section with respect to the main body section or the display panel is reduced. In some cases, the arrangement of the operation buttons is restricted depending on the position of the support portion.

[Overall configuration of display device]
FIG. 1 is a schematic perspective view showing an appearance of a display device 1000 according to an embodiment of the present invention. Here, FIG. 1A is a schematic perspective view showing a state in which the display device 1000 is viewed from the upper right of the front. FIG. 1B is a perspective view showing a state in which the display device 1000 is viewed from the back and upper right of the display device 1000. FIG. FIG. 2 is a schematic perspective view showing a state in which the display device 1000 is viewed from the left side of the front.

  As shown in FIGS. 1 and 2, the display device 1000 according to the present embodiment includes a main body stand unit 100, an arm unit (support unit) 200, and a display display unit (display unit) 300. The display device 1000 receives, for example, a television broadcast image and displays it on the display screen 300a of the display display unit 300.

  The display unit 300 includes a display panel (organic EL panel) 320 that displays an image using an organic electroluminescence (EL) phenomenon. The organic EL panel 320 includes a plurality of organic EL elements that are self-luminous elements and does not require a configuration such as a backlight, and thus the thickness thereof is sufficiently thin. As shown in FIG. 2, the display display unit 300 of the present embodiment has a thickness t that is suppressed to about several mm (about 3 mm) or less, and is a thin panel with a very small thickness.

  The arm part 200 is provided at one position behind the main body stand part 100 and is erected upward from the main body stand part 100. The arm unit 200 is provided on the right side of the horizontal (horizontal) center of the main body stand unit 100 when the display device 1000 is viewed from the front, and on the right side of the horizontal center of the display display unit 300. It is connected to. As described above, in the display device 1000 according to the present embodiment, the arm unit 200 is provided on either the left or right end side of the display display unit 300 in the horizontal direction, and the display display unit 300 is supported in a cantilever manner. Yes. The arm unit 200 may be connected to the horizontal end of the display unit 300. Further, the upper end of the arm unit 200 may be connected to the vicinity of the center of the display display unit 300 in the horizontal direction, and the lower end may be connected to the end of the main body stand unit 100 as shown in FIG.

  A circuit board (O board), a circuit board (B-CAS board) that performs signal processing for driving the display display unit 300, a cooling fan, a heat sink (heat spreader), etc. are compact in the main body stand unit 100. It has been incorporated. The main body stand unit 100 incorporates tuners for satellite broadcasting (BS, CS), terrestrial digital waves, etc., and various terminals such as LAN, HDMI, USB, etc., on the back side for receiving terrestrial digital waves. A rod antenna 104 (see FIG. 1B) is provided. The main body stand unit 100 incorporates a speaker box, operation buttons, and the like.

  In the case of a liquid crystal display, since a backlight is necessary, the thickness of the display display unit is increased and the weight is also increased. In particular, as in the present embodiment, when it is assumed that the display is not a computer display but a TV image display, in order to ensure image quality as a television receiver, more than a computer display. It is necessary to arrange a backlight. In addition to the backlight, the liquid crystal display also requires an inverter for controlling the backlight. For this reason, in the case of a liquid crystal display, in order to support the display display unit in a cantilevered manner, it is necessary to greatly increase the rigidity of the display unit including the arm unit. An increase is assumed. Therefore, it is not realistic to support the liquid crystal display in a cantilever manner in consideration of user convenience, manufacturing cost, and the like.

  On the other hand, since the organic EL panel is composed of an organic EL element which is a self-luminous element, no components such as a backlight or an inverter associated therewith are required, and the organic EL panel is configured to be lightweight only with a thin glass panel. Can do. Therefore, according to the present embodiment, the display display unit 300 itself can be configured to be very lightweight, and the display display unit 300 can be supported in a cantilever manner.

  The display display unit 300 is pivotable in the direction of arrow A1 in FIG. 2 around the connecting portion with the arm unit 200, and the user sets the tilt position of the display display unit 300 to a desired angle. Can do.

  In the conventional display panel, the member that supports the display panel supports the central portion in the horizontal direction of the display panel from the lower side in the case of one-point support. In the case of two-point support, the vicinity of both ends in the horizontal direction of the display panel is supported from below. In the present embodiment, the arm unit 200 is arranged so as to be shifted from the lateral central portion of the display display unit 300 and the display display unit 300 is supported in a cantilevered manner. Thus, only the display screen 300a can be recognized independently. Thereby, an impression can be given to the user as if the display display unit 300 is floating on the main body stand unit 100 without the arm unit 200 interposed therebetween. Therefore, by supporting the display display unit 300 in a cantilever manner, it becomes possible for the user to gaze at the display screen 300a independently.

  Moreover, it is not necessary to connect the base of the arm part 200 to the center of the main body stand part 100, and the freedom degree of installation of the arm part 200 improves. Therefore, it is possible to determine the installation position of the arm unit 200 with respect to the main body stand unit 100 in consideration of the internal structure of the main body stand unit 100, the arrangement of the substrates, and the like, and the degree of design freedom can be increased. Accordingly, it is possible to arrange the constituent members most efficiently in consideration of the internal structure of the main body stand unit 100, and it is possible to minimize the size of the display device 1000. In addition, since the arm unit 200 is not installed at the center of the main body stand unit 100, an effective space can be widened on the upper surface of the main unit stand unit 100, and a display unit, operation buttons, LED indicator lamps are provided on the upper surface of the main unit stand unit 100. Etc. can be arranged freely.

  As shown in FIGS. 1 and 2, the arm part 200 is provided to be inclined from the rear of the main body stand part 100 toward the back surface of the display display part 300. In FIG. 2, the inclination angle θ of the arm unit 200 with respect to the vertical direction is a value of about 45 ° to 60 °. Accordingly, when the display display unit 300 is viewed from the front, the arm unit 200 is hidden behind the display display unit 300, and the arm unit 200 is suppressed from being recognized within the user's field of view. Therefore, it is possible to reliably suppress the arm unit 200 from being recognized in the user's field of view due to a synergistic effect with the arrangement of the arm unit 200 shifted from the center of the display display unit 300.

  For this reason, only the display display unit 300 and the main unit stand unit 100 are shown in the user's visual field, and the arm unit 200 hardly enters the visual field, so that the user can directly change the connection state between the display display unit 300 and the main unit stand unit 100. It is suppressed to recognize. Therefore, the user feels as if the display display unit 300 is floating in the space.

  In addition, as described above, in the configuration of the present embodiment, the thickness of the display display unit 300 is very thin, such as several millimeters, so that the lightweight feeling of the display display unit 300 is emphasized and recognized by the user. The Therefore, for the user, the display display unit 300 having a very floating feeling and light weight is provided by a synergistic effect with the feeling that the display display unit 300 is floating in the space.

  Thereby, the user can watch the display content of the display display unit 300 recognized as floating in the space, and concentrate the display content without being concerned about other structures. Can see. Accordingly, it is possible to provide a display device 1000 that can maintain a good design while producing a feeling that the display screen 300a is floating for the user, and greatly improve the visibility of the display screen 300a. Is possible.

  As shown in FIG. 2, the tip of the arm unit 200 on the display display unit 300 side is inclined downward by an angle α from the horizontal plane toward the display display unit 300. According to such a configuration, the receiving surface 202 of the arm part 200 with respect to the shaft 366 of the hinge part 360 described later can be set to a lower position. Accordingly, the position of the display display unit 300 can be lowered relative to the arm unit 200, and the arm unit 200 can be made less visible to the user.

  Furthermore, as shown in FIG. 3, the arm unit 200 may be configured by only the first arm unit 210. In this case, when the display device 1000 is viewed from the front side, the display arm 300 is supported only by the first arm unit 210 located on the far side by eliminating the second arm unit 220 located on the near side. be able to. Therefore, it can be set as the structure which makes a user not be aware of the presence of the arm part 200 more.

[Configuration of arm part]
FIG. 4 is a schematic diagram showing the configuration of the arm unit 200. As shown in FIG. 4, the arm part 200 has an opening 230 penetrating the side surface along the longitudinal direction thereof, and has a hollow structure. And by setting it as such a hollow structure, the arm part 200 is comprised from the 1st arm part 210 located in the upper part, and the 2nd arm part 220 located in the lower part. The first arm part 210 and the second arm part 220 are formed in a thin flat plate shape and face each other with the opening 230 interposed therebetween, and the thickness of the first arm part 210 and the second arm part 220 is minimal. Is suppressed.

  As described above, the display display unit 300 is very thin and has a light weight feeling and a floating feeling. Therefore, the arm unit 200 that supports the display display unit 300 can also be configured to have a light and floating feeling like the display display unit 300 by minimizing the thickness as a hollow structure. As a whole, the display device 1000 can emphasize lightness and floating feeling.

  As described above, since the liquid crystal display is heavy, it is difficult to make the arm portion a hollow structure and to have a light and light feeling in order to ensure strength. In the present embodiment, since the display unit 300 is configured by the organic EL panel 320, the required strength can be ensured even when the arm unit 200 has a hollow structure. Therefore, it is possible to reliably support the display display unit 300 and to secure a good design that is light and light.

  A cover 240 is placed on the upper surface of the first arm part 210. A flexible printed circuit board 250 that electrically connects the main body stand unit 100 and the display display unit 300 is built in between the upper surface of the first arm unit 210 and the cover 240.

  FIG. 5 is a schematic diagram showing the configuration of the arm unit 200 in detail. Here, FIG. 5 (A) is a front view showing a state in which the arm unit 200 is viewed from the front side of the display unit 300, FIG. 5 (B) is a left side view, and FIG. 5 (C) is a right side view. 5D is a top view, FIG. 5E is a bottom view, FIG. 5F is a rear view, and FIG. 5G is a cross section taken along the alternate long and short dash line II ′ in FIG. 5C. FIG. The main body portion of the arm portion 200 with the cover 240 removed can be configured as an integral block by casting or cutting, for example, using a metal such as aluminum.

  As described above, by configuring the display display unit 300 from the organic EL panel 320, it is possible to minimize the weight of the display display unit 300, and ensure the necessary strength even if the arm unit 200 has a hollow structure. can do. In addition, the arm unit 200 has a hollow structure, and the volume of the arm unit 200 is minimized, so that the user can be caused to feel floating and light with the light and thin display display unit 300. . In addition, since the flexible printed circuit board 250 is built in the first arm unit 210, the user can be prevented from being aware of the presence of the wiring.

  Further, the arm portion 200 may be made of a transparent resin material such as polycarbonate or acrylic, or transparent glass. By making the arm part 200 transparent, it is possible to make the user less aware of the presence of the arm part 200. Therefore, it is possible to make the user gaze at the display screen 300a, and to make the user feel more floating and lightness of the display device 1000.

  FIG. 6 is a schematic view showing another aspect of the display device 1000 of the present embodiment. In the ideographic apparatus 1000 shown in FIG. 6, the opening 230 of the arm unit 200 is provided so as to penetrate through the display apparatus 1000.

  FIG. 7 is a schematic diagram showing the configuration of the arm unit 200 of the display device 1000 of FIG. As shown in FIG. 7, the arm part 200 has a hollow structure by an opening 230 formed in the front-rear direction. In such a configuration of the arm part 200 as well, the thickness can be minimized by forming the opening 230 to have a hollow structure. Therefore, similarly to the display display unit 300, the arm unit 200 can be configured to have a light feeling and floating feeling, and the display apparatus 1000 as a whole can emphasize the light feeling and floating feeling.

  Various other shapes of the arm part 200 are conceivable. For example, you may provide the opening 230 for setting it as a hollow structure in several places. Further, in the configuration of FIG. 1, the arm unit 200 is configured by dividing the first arm unit 210 and the second arm unit 220 by providing the opening 230, but may be divided into more arm units.

  FIG. 8 is a schematic diagram showing another aspect of the display device 1000 of the present embodiment. In the ideographic apparatus 1000 shown in FIG. 8, the arm unit 200 is erected from the side surface of the main body stand unit 100. It is attached to. According to such a configuration, since the arm unit 200 is not erected from the upper surface of the main body stand unit 100, the presence of the arm unit 200 can be more reliably removed from the user's field of view. Therefore, the lightness and floating feeling of the display device 1000 can be emphasized.

  FIG. 9 shows an aspect of the display device 1000 in which a shaft 366 of a hinge portion 360 described later is disposed above the display device 1000 of FIG. 1 and the arm portion 200 is connected to the shaft 366. According to such a configuration, since the arm unit 200 is connected to the upper part of the display display unit 300, when the display device 1000 is viewed from the front, a larger range of the arm unit 200 is included in the display display unit 300. Hidden behind. Therefore, it can be set as the structure which does not make a user conscious of presence of the arm part 200, and can produce the feeling of lightness of a display apparatus 1000 and a floating feeling more.

  FIG. 10 shows an example in which the lower end of the arm unit 200 is connected to the front right side of the main body stand unit 100 and the upper end of the arm unit 200 is connected to the front left side of the display display unit 300. Since the organic EL panel is very light, such a connection is also possible by making the arm part 200 long. Even in this case, the thickness of the arm part 200 can be minimized, and the display device 1000 can have a light feeling and a floating feeling.

[Configuration of display unit]
FIG. 11 is a schematic diagram showing the configuration of the display display unit 300, and shows an exploded perspective view of the display display unit 300.

  The base plate 340 is a member constituting a main skeleton of the display display unit 300, and the arm unit 200 is connected to the base plate 340 via the hinge unit 360. Further, main components such as the organic EL panel 320, the T substrate 350, and the hinge part 360 are fixed to the base plate 340. Main members constituting the display unit 300 such as the organic EL panel 320, the T substrate 350, the hinge part 360, the rear cover 420, and the T cover 430 are all attached with the base plate 340 as a reference.

  A graphite sheet 330 is attached to the back surface of the organic EL panel 320. The organic EL panel 320 is fixed to the base plate 340 with an adhesive tape with the surface on which the graphite sheet 330 is attached facing the base plate 340.

  The T substrate 350 is made of a hard substrate, and is connected to a power line and a signal line connected to the organic EL panel 320. The size of the T substrate 350 corresponds to the size of the base plate 340, and the T substrate 350 is fixed to the opposite side of the surface to which the organic EL panel 320 is fixed with respect to the base plate 340.

  The hinge part 360 is a structural member that connects the arm part 200 and the base plate 340. The hinge part 360 is configured to include components such as a metal first hinge plate 362 and a second hinge plate 364 having a triangular planar shape, a metal shaft 366, and the like. The shaft 366 is horizontally disposed along the lower end of the display display unit 300. The first hinge plate 362 and the second hinge plate 364 are fixed to the base plate 340 and attached to the shaft 366 so as to be rotatable. On the other hand, the shaft 366 is fixed to the arm portion 200. Accordingly, the base plate 340 can be rotated with respect to the shaft 366 fixed to the arm portion 200, and at this time, the rotation center axis becomes the center axis of the shaft 366. Thereby, as described above, the display display unit 300 can be rotated in the direction of the arrow A1 in FIG. 2, and the tilt angle of the display display unit 300 can be varied.

  The bezel 310 is a member that is attached to the edge of the organic EL panel 320 and configures the appearance of the edge of the display display unit 300. The rear cover 420 and the T cover 430 are metal covers that cover the back surface of the display display unit 300. The rear cover 420 is provided with an opening 422 in a portion corresponding to the position of the T substrate 350 and the hinge part 360 and mainly covers the upper part of the back surface of the display display part 300. On the other hand, the T cover 430 is attached corresponding to the position of the opening 422 and is configured to cover the T substrate 350 and the hinge part 360.

  The base plate 340, the T substrate 350, and the hinge 360 part are all provided only in the area below the lower half of the display display unit 300, and the base plate 340, T substrate is compared to the entire area of the display display unit 300. The area occupied by 350 and the hinge 360 part is minimized. On the other hand, except for the region where the base plate 340, the T substrate 350, and the hinge 360 portion are disposed, the thickness of the display display portion 300 is mainly determined only for the three members of the organic EL panel 320, the graphite sheet 330, and the rear cover 420. Therefore, particularly in the region including the upper half of the display display unit 300, the thickness of the display display unit 300 can be made extremely thin, and the thickness can be suppressed to about 3 mm as described above.

  Usually, since the display device 1000 is arranged on a desk or the like, the user hardly sees the display display unit 300 from the lower side, and the thickness of the display display unit 300 is recognized from the upper side. Therefore, the members such as the base plate 340, the T substrate 350, and the hinge part 360 are disposed below the display display unit 300, and the thickness on the upper side of the display display unit 300 is minimized to display to the user. The thinness of the display unit 300 can be emphasized. Therefore, it is possible to maintain a good design while producing the floating feeling and the light feeling as described above.
