When the first casing and the second casing are fully opened by 180 °, one three-dimensional image is displayed on both the first display device and the second display device. It can be switched to.

  According to said structure, when opening and closing a 1st housing | casing and a 2nd housing | casing by a hinge part, the surface side corner | angular part of a 1st display apparatus and the surface side corner | angular part of a 2nd display apparatus Are controlled so as to move along a linear locus with respect to the hinge portion without interfering with each other. For this reason, even if the surface (cover) of the first display device and the surface (cover) of the second display device each have a thickness, the fully closed operation can be performed smoothly while maintaining a contact state with each other. It becomes possible. When viewing a 3D image in a portable place, if you do not want to be seen by the people around you, the 3D image is deepened by reducing the opening / closing angle between the first and second housings. Because it is displayed in position, you can watch without worrying about the gaze around you. On the other hand, if it can be seen by surrounding people, the viewing angle can be increased while gradually increasing the open / close angle and the 3D image can be viewed in a more pop-up state, so that it can be viewed with a higher sense of reality. And, when you want to show it to the people around you or appreciate it on a screen as large as possible, the function of the hinge part allows the 3D image by the first display device and the 3D image at night to be continuously displayed on the second display device during the fully open operation. By doing so, it is possible to display the largest and pop-out 3D image.

In the three-dimensional display mode, at the time of opening / closing operation for opening and closing the first casing with respect to the second casing, only the first display device displays a three-dimensional image, and the first display device As the opening / closing angle with respect to the second display device increases, the three-dimensional display gradually changes from a small image to a large image,
When the first casing and the second casing are fully opened by 180 °, one three-dimensional image is displayed on both the first display device and the second display device. It can be switched to.

  According to said structure, when opening and closing a 1st housing | casing and a 2nd housing | casing by a hinge part, the surface side corner | angular part of a 1st display apparatus and the surface side corner | angular part of a 2nd display apparatus Are controlled so as to move along a linear locus with respect to the hinge portion without interfering with each other. For this reason, even if the surface (cover) of the first display device and the surface (cover) of the second display device each have a thickness, the fully closed operation can be performed smoothly while maintaining a contact state with each other. It becomes possible. When viewing a 3D image in a portable place, if you do not want to be seen by people around you, you can display a small 3D image by reducing the opening / closing angle between the first and second housings. You can watch without worrying about the gaze around you. On the other hand, if it can be seen by surrounding people, the viewing angle can be increased while gradually increasing the opening / closing angle, and viewing with a larger three-dimensional image can be performed while obtaining a more realistic feeling. And, when you want to show it to the people around you or appreciate it on a screen as large as possible, the function of the hinge part allows the 3D image by the first display device and the 3D image at night to be continuously displayed on the second display device during the fully open operation. By doing so, the most realistic 3D image can be displayed.

In the third invention, in the first or second invention,
The hinge part is
First and second guide pins respectively coupled to opposing side surfaces of the first housing;
A first guide hole extending in the first direction and restricting the movement locus of the first guide pin and a second guide hole extending in a second direction different from the first direction and restricting the movement locus of the second guide pin. When,
Third and fourth guide pins respectively coupled to the opposing side surfaces of the second housing;
A third guide hole extending in the third direction and restricting the movement locus of the third guide pin and a fourth guide hole extending in a fourth direction different from the third direction and restricting the movement locus of the fourth guide pin And.

  According to said structure, the movement locus | trajectory of each surface side corner | angular part can be adjusted appropriately by regulating the movement locus | trajectory of each guide pin by adjusting the shape of the 1st-4th guide hole. For this reason, it is possible to restrict the movement so that each surface side corner is not too close and not too far away. For this reason, it is possible to enjoy a large two-dimensional image that is continuous during opening and closing.

In a fourth invention, in any one of the first to third inventions,
When the opening angle of the first and second housings reaches 180 degrees, the back surfaces of the first and second housings become flat and can be locked in this state.

  According to said structure, since a back surface side is completely flat at the time of 180 degrees full open, it does not wobble on a desk etc. and operation is easy. Further, since it is fixed in the fully opened state, a continuous large screen can be more easily seen when displaying either a two-dimensional image or a three-dimensional image if tilted appropriately.

It is comprised so that it may contact in a side edge part.

  That is, when each display module is arranged on the back side of each fixed plate fixed to each case, the first and second cases can be opened and closed so that the interval between the fixed plates is not opened. However, the interval between the display modules is widened, and the images of the display modules cannot be displayed continuously. However, according to the above configuration, each module slides toward the hinge side end portion within each housing in accordance with the opening / closing operation of the first and second housings. It is possible to maintain a state in which the end of each display module is brought into contact with the hinge portion side end. Thus, it is possible to display a continuous two-dimensional image during the opening / closing operation.

  That is, a typical liquid crystal panel as a display panel has a display area in which a plurality of pixels are arranged and a frame area around the display area. In the frame area, a pair of glass substrates are opposed to each other and a liquid crystal layer is formed. There are provided a seal portion for hermetically holding and a drive circuit mounting portion for driving the pixels. For this reason, since there is a frame area that does not contribute to display on the liquid crystal display panel, when a large screen is formed by arranging a plurality of liquid crystal display panels, a seam is generated in the image. This problem is not limited to liquid crystal display devices, but is a common problem for direct-view display devices such as PDPs, organic EL display devices, and electrophoretic display devices. However, according to the above configuration, the display area is expanded to the full extent of the hinge-side end portions of the first and second display panels by the light guide elements provided on the hinge-side surface end portions of the first and second display panels. Therefore, each display area can be shown to be completely continuous. For this reason, it is possible to enjoy a continuous two-dimensional image while the first and second casings are opened and closed, and in the fully opened state, there is no seam in which the two images are continuous in both the two-dimensional image and the three-dimensional image. A large screen can be realized.

In the seventh invention, in the fifth or sixth invention,
The first and second display modules are urged by the urging members so as to contact each other.

  According to the above configuration, the display modules can be slid and moved in contact with each other in accordance with the opening / closing operation of the first and second housings with a simple configuration. For this reason, it is possible to reliably display a continuous image both in the middle of opening and closing and in the fully opened state.

In an eighth invention, in any one of the fifth to seventh inventions,
The first and second display panels are made of parallax barrier liquid crystal.

  According to the above configuration, since 3D display can be performed with a simple configuration without using glasses, a 3D image can be easily enjoyed anytime and anywhere.

In a ninth invention, in any one of the fifth to seventh inventions,
The first and second display panels have a switch panel that makes the parallax barrier transparent during two-dimensional display and causes the parallax barrier to appear during three-dimensional display,
The direction in which the parallax barriers of the switch panel are arranged can be switched to either perpendicular or parallel to the axial direction of the hinge portion.

  According to the above configuration, by arranging the images corresponding to the parallax barrier and the left and right eyes according to how to hold the foldable mobile terminal, even if you hold it up and down, if you hold it up and down However, a realistic 3D display is displayed.

  As described above, according to the present invention, when the first casing and the second casing are opened and closed by the hinge portion connecting the first casing and the second casing. In addition, while restricting the movement trajectory between the surface side corner of the first display device and the surface side corner of the second display device in a side view, the projection state of the three-dimensional image according to the open / close angle, The size can be adjusted, and the three-dimensional images of the first display device and the second display device are continuously displayed when fully opened, so that a three-dimensional display image can be displayed according to the user's viewing situation. It is possible to change and enjoy a 3D video comfortably, and when performing 2D display, it is possible to smoothly perform opening and closing operations while continuing 2D images on two screens in the middle of opening and closing.

Of course you can also. As will be described in detail later, the first display device and the second display device are configured to be able to select and display either a two-dimensional image or a three-dimensional image.

  As shown in FIGS. 7 to 12, the first and second housings 3 and 5 are made of, for example, a hollow resin molded product, a metal molded product, or the like, and the first on the observer side (surface side). And the second main cavities 3a and 5a, and the first and second rear cavities 3b and 5b on the back surface side, respectively. First and second fixing plates 7 and 8 each including a transparent resin sheet, a resin panel, etc. are fitted on the surface sides of the first and second main cabinets 3a and 5a, respectively, and are fixed by a double-sided tape or the like. Each of the first and second fixing plates 7 and 8 includes a touch panel 9 on the back surface side. The back surfaces of the first and second rear cabinets 3b and 5b are flat.

  First and second display modules 11 and 12 are disposed inside the first and second fixing plates 7 and 8, respectively. The first display module 11 includes a first liquid crystal panel 13 as a first display panel on the surface side. A first backlight 15 is provided on the back side of the first liquid crystal panel 13. The first display module 11 is arranged to be slidable in the vertical direction (vertical direction) with respect to the hinge portion 6 with respect to the first housing 3. Similarly, the second display module 12 includes a second liquid crystal panel 14 as a second display panel on the surface side. A backlight 16 is also provided on the back side of the second liquid crystal panel 14. The second display module 12 is arranged to be slidable in the vertical direction (vertical direction) with respect to the hinge portion 6 with respect to the second housing 5.

  Although not shown in detail, the first and second liquid crystal panels 13 and 14 may be arbitrary known liquid crystal display panels, for example, TFT type VA mode liquid crystal display panels. The first and second liquid crystal panels 13 and 14 each have a TFT substrate and a counter substrate, and a liquid crystal layer is provided between the TFT substrate and the counter substrate. The TFT substrate is provided with TFTs and pixel electrodes, and the counter substrate is provided with color filters and counter electrodes. The liquid crystal layer is held between the TFT substrate and the counter substrate by the seal portion.

The optical film layer includes a polarizing plate and a retardation plate provided as necessary. In the present embodiment, the first and second liquid crystal panels 13 and 14 are configured to be able to select and display either a two-dimensional image or a three-dimensional image. In the parallax barrier method that enables three-dimensional display, as shown in FIG. 18, the left-eye image L and the right-eye image R are arranged on the liquid crystal panel with an interval, and a parallax barrier is provided on the front side thereof. Thus, the left eye image L is displayed on the left eye, and the right eye image R is displayed on the right eye, so that a three-dimensional three-dimensional image can be displayed. In order to use this principle, as shown in FIGS. 10 and 19, the switch liquid crystal 19 is provided on the backlights 15 and 16 side of the first and second liquid crystal panels 13 and 14, respectively. Yes. Thus, as shown in FIG. 19A, in the case of two-dimensional display, the parallax barrier of the switch liquid crystal 19 is made transparent to display a planar image as it is, and as shown in FIG. In the case of three-dimensional display, a stereoscopic image can be displayed by separating light by causing a parallax barrier to emit light. For the left-eye image L and the right-eye image R, for example, images that are respectively captured by cameras that are arranged with an appropriate distance between the left and right may be used.

  On the other hand, by providing the folding portable terminal 1 with the opening / closing direction detection unit 62, the user holds the folding portable terminal 1 in a direction that opens up and down like a notebook computer, or a direction that opens left and right like a newspaper.

Then, the folding mobile phone in which the opening / closing direction detection unit 62 detects the arrangement direction of the parallax barrier of the switch liquid crystal 19 and the arrangement direction of the left-eye image L and the right-eye image R on the first and second liquid crystal panels 13 and 14. By changing according to how the terminal 1 is held, three-dimensional display can be performed both when the opening operation is performed up and down and when the opening operation is performed left and right.

  Although not shown in detail, the first rear cabinet 3b is provided with a first substrate 17, and the second rear cabinet 5b is provided with a second substrate 18 (both shown only in FIG. 7). The second rear cabinets 3b and 5b are provided with batteries. The first substrate 17 and the second substrate 18 are connected to each other by a flexible substrate or the like. As shown in FIG. 20, for example, a CPU 70 is provided on the first substrate 17 or the second substrate 18, and each component is connected to the CPU 70 via a system bus 71. The first and second display modules 11 and 12 are controlled by the display module controller 72.

  As shown in FIG. 10, each of the first and second liquid crystal panels 13 and 14 has a display area 20 in which a plurality of pixels are arranged, and a frame area 21 around the display area 20. The frame region 21 is provided with a seal portion for holding a pair of glass substrates facing each other and holding the liquid crystal layer in a sealed state, a drive circuit mounting portion (none of which is shown) for driving the pixels, and the like. It has been. For this reason, the first and second liquid crystal panels 13 and 14 have a frame region 21 that does not contribute to display.

  The surfaces of the first and second liquid crystal panels 13 and 14 of this embodiment are each covered with a light guide panel 24, and a light guide element 25 is provided at the end of the light guide panel 24 on the hinge 6 side. Yes. With this light guide element 25, the image in the vicinity of the frame region 21 in the display region 20 is expanded to the full end of the first liquid crystal panel 13 on the hinge 6 side. Although the light guide element 25 is not illustrated in detail, for example, a stacked body in which a plurality of transparent layers and a plurality of metal layers are stacked can be used. The light incident on the light guide element 25 from the incident surface propagates in the transparent layer in parallel with the side surface, and is emitted from the emission surface toward the observer side. At this time, the light incident on the transparent layer propagates in the transparent layer while being reflected by the adjacent metal layer. Although light is incident on the incident surface from various angles, the sheet laminated body uses metal reflection in the metal layer, and thus can guide all light regardless of the incident angle. In addition, as the light guide element 25, one having a plurality of light guide parts including a substantially cylindrical transparent part in which at least a part of the side surface is covered with a metal part can be used. Further, as the light guide element 25, a sheet laminate in which a plurality of light transmissive layers are laminated can be used. In addition, the seam processing is performed by the image processor 73, and the three-dimensional display is also controlled by the three-dimensional graphic engine.

  For example, as shown in FIG. 13, the first and second housings 3 and 5 have rectangular housing recesses 3c and 5c in which the first and second display modules 11 and 12 are respectively housed. The left and right side walls are formed as a pair of slide side walls 3d and 5d extending in the vertical direction perpendicular to the longitudinal direction of the hinge portion 6, respectively. Further, the first and second display modules 11 and 12 are pressed toward the hinge portion 6 by a leaf spring 27 as an urging member disposed on the wall surface of the housing recesses 3c and 5c opposite to the hinge portion 6 respectively. Are biased so as to abut against each other. Accordingly, the left and right side surfaces of the first and second display modules 11 and 12 are slidably contacted with the slide side walls 3d and 5d, respectively, and slide along the slide side walls 3d and 5d. Since the leaf spring 27 is selected as the urging member, it is lightweight and strong, and a large stroke is ensured even in a narrow gap.

  For example, as shown in FIG. 14, stop concave portions 28 a that are recessed left and right are formed in the slide side walls 3 d and 5 d of the first and second casings 3 and 5, respectively. The first and second backlights 15 and 16 of the first and second display modules 11 and 12 are formed with protrusions 28b that protrude outward in the left and right directions, corresponding to the stop recesses 28a. When the opening / closing angle α of the first and second casings 3 and 5 is equal to or less than a predetermined angle due to the combination of the stop recesses 28a and the corresponding projections 28b, the first and second display modules 11 and 12 slide. It plays the role of a stopper 28 that regulates movement. Specifically, for example, when the opening / closing angle α becomes 90 ° (α = 90 °), the projection 28b comes into contact with the inner wall 28c in the sliding direction of the stop recess 28a and the first and second display modules 11, 12 slide movements are restricted.

  As shown in FIGS. 10 to 12, when the hinge 6 opens and closes the first housing 3 and the second housing 5, the hinge 6 is on the surface side of the first display device 2 in a side view. The corner, that is, the hinge-side corner 7a of the first fixed plate 7 and the surface-side corner of the second display device 4, that is, the hinge-side corner 8a of the second fixed plate 8 are in contact with each other. The first housing 3 and the second housing 5 are connected so as to move in a linear locus with respect to the hinge portion 6 in a state of contact. Furthermore, when the first casing 3 and the second casing 5 are fully closed by the hinge section 6, the hinge section side corner section 7 a of the first fixing plate 7 and the hinge section side of the second fixing plate 8 are used. The corner portion 8a is arranged with a predetermined gap c therebetween.

  As shown in FIGS. 15 to 17, the hinge portion 6 is made of metal or reinforced to cover the left and right side surfaces 3 e and 5 e of the opposite ends of the first and second housings 3 and 5 from the outside, respectively. A guide plate 30 made of fiber resin or the like is provided. In addition, the hinge portion 6 includes first and second guide pins 31 and 32 that are connected to the left and right side surfaces 3e of the first housing 3 that are opposed to each other with a space therebetween, and the second housing 5 is opposed to the hinge portion 6. Third and fourth guide pins 41 and 42 connected to the left and right side surfaces 5e with a space therebetween are provided.

  The guide plate 30 includes a first guide hole 33 that extends in the first direction and restricts the movement trajectory of the first guide pin 31. A 1st direction shows the thickness direction (up-down direction of FIG. 7), when the folding portable terminal 1 is fully opened at 180 degrees. Although it is not clear in FIG. 15 and the like, for example, the end portion of the first guide hole 33 is slightly curved leftward in FIG. The second guide pin 32 has a flange 32 a having a diameter larger than that of the second guide hole 34, and is prevented from coming off from the second guide hole 34. Further, the guide plate 30 is formed with a second guide hole 34 that extends in a second direction different from the first direction and regulates the movement locus of the second guide pin 32. Similarly, the second direction indicates a horizontal direction when the foldable portable terminal 1 is fully opened at 180 °. In the present embodiment, the second guide hole 34 has a linear shape substantially perpendicular to the first guide hole 33, but may be inclined or curved with respect to the first guide hole 33.

  Similarly, the guide plate 30 includes a third guide hole 43 that extends in the third direction and restricts the movement trajectory of the third guide pin 41. A 3rd direction shows the thickness direction when the foldable portable terminal 1 is fully opened to 180 degrees. Although not obvious in FIG. 15 and the like, the end of the third guide hole 43 is also slightly curved to the right in FIG. The fourth guide pin 42 also has a flange 42 a having a diameter larger than that of the fourth guide hole 44, and is prevented from being detached from the fourth guide hole 44. Further, the guide plate 30 is formed with a fourth guide hole 44 that extends in a fourth direction different from the third direction and restricts the movement trajectory of the fourth guide pin 42. The fourth direction indicates the horizontal direction when the folding portable terminal 1 is fully opened at 180 °. In the present embodiment, the fourth guide hole 44 has a linear shape substantially perpendicular to the third guide hole 43, but may be inclined or curved with respect to the third guide hole 43.

  The shapes of the first and third guide holes 33 and 43 and the first and third guide holes 34 and 44 are plane loci determined by three points together with the corners of the first and second housings 3 and 5, respectively. The trajectories of the corners of the first and second casings 3 and 5 can be arbitrarily set.

  As seen from the front side of FIG. 7, the first direction and the third direction are bilaterally symmetric, and similarly, the second direction and the fourth direction are bilaterally symmetric.

  The first and third guide pins 31 and 41 are connected to each other by a connecting portion 51 on the guide plate 30 opposite to the first and second housings 3 and 5. The connection part 51 consists of a resin molded product, a metal molded product, etc., and may have flexibility like an elastomer.

  A linear fifth guide hole 50 is formed between the first and third guide holes 33 and 43 on the guide plate 30. In the state shown in FIG. 7, the fifth guide hole 50 is disposed slightly shifted downward from the first and third guide holes 32 and 42. A fifth guide pin 52 coupled to the connecting portion 51 of the first and third guide pins 31 and 41 is inserted into the fifth guide hole 50.

  With such a simple configuration, the movement of each guide pin 31, 32, 41, 42 can be restricted.

  The hinge portion 6 includes a protective cover 60 that covers the hinge portion 6 side ends of the first and second casings 3 and 5. Specifically, the protective cover 60 is connected to the left and right guide plates 30 and is made of a flexible material having a rectangular frame shape equivalent to the outer periphery of the guide plates 30. The protective cover 60 prevents the inside of the first and second casings 3 and 5 from appearing in the appearance. The protective cover 60 may be formed of a metal molded product, or the guide plate 30 and the protective cover 60 may be integrally formed to reduce the number of parts.

  With such a configuration of the hinge portion 6, during the folding opening / closing operation, the first fixed plate 7 and the second fixed plate 8 are in contact with each other at the hinge portion 6 side end, and the first and second display modules 11, 12 is configured to slide so as to come into contact with each other and to contact at the end of the hinge 6 side. When the opening angle α of the first and second casings 3 and 5 reaches 180 degrees (α = 180 °), the first and second rear cabinets 3b and 5b and the protective cover 60 are flat. It has become. In this flat state, the first and second casings 3 and 5 are configured so as to be able to be locked so as not to be opened and closed from a state where the opening / closing angle α is 180 ° by a mechanical locking means or the like (not shown).

  Although not shown in detail, the hinge portion 6 is provided with an opening / closing angle detection portion 63 that detects an opening / closing angle α between the first housing 3 and the second housing 5. The configuration of the opening / closing angle detection unit 63 is not particularly limited, and may be configured with various contact sensors and non-contact sensors.

-How to use a foldable mobile terminal-
Next, an example of the usage method of the foldable portable terminal 1 according to the present embodiment will be described.

  As shown in FIG. 21, first, the power is turned on in step S01.

  Next, in step S02, selection of an image to be displayed is selected.

  In step S03, a three-dimensional image or a two-dimensional image on an external or internal storage medium or by wireless or wired communication is selected. If a two-dimensional image is selected, the process proceeds to step S04.

  In step S04, it is selected whether the two-dimensional image is displayed as it is as a two-dimensional image or whether the two-dimensional image is displayed as a pseudo three-dimensional image.

  When displaying as a two-dimensional image, it progresses to step S05 and a two-dimensional image is displayed.

<2D display>
When displaying a two-dimensional image, first, when the folding portable terminal 1 shown in FIG. 1 is fully opened at 180 °, the first and second fixed plates 7 and 8 are completely continuously connected to one plate-like terminal. looks like.

  At this time, as shown in FIG. 15, the first, third, and fifth guide pins 31, 41, 52 are the thicknesses of the hinge portions 6 in the first, third, and fifth guide holes 33, 43, 50, respectively. Located at the top of the direction. The second and fourth guide pins 32 and 42 are located at the ends of the left and right center sides of the second and fourth guide holes 34 and 44, respectively. In this fully open posture, the protective cover 60 covers the hinge 6 side ends of the first and second casings 3 and 5, so that the interiors of the first and second casings 3 and 5 are not exposed. , Looks good. Moreover, since the entire back surface side including the protective cover 60 is completely flat, it can be operated comfortably without wobbling on a desk or the like. As shown in FIG. 13, the first and second display modules 11 and 12 are urged by the leaf springs 27 to contact each other on the hinge part 6 side and are continuous. In addition, as shown in FIG. 10, the display area 20 of the first and second liquid crystal panels 13, 14 is formed by the light guide element 25 provided at the hinge end side surface ends of the first and second liquid crystal panels 13, 14. The hinge part 6 is widened to the full end. Then, by performing the seam processing with the image processor 73, it is possible to make each display region 20 appear to be completely continuous. Therefore, it is possible to realize a seamless large screen in which two two-dimensional images are continuous. Further, since the first and second fixing plates 7 and 8 each include the touch panel 9, a finger is continuously moved between the first and second housings 3 and 5 while viewing continuous images. The smooth touch panel 9 can be operated. In addition, since it is fixed in the fully opened state, a large two-dimensional image becomes easier to see if it is tilted appropriately.

  From the fully opened state, as shown in FIGS. 2 and 3, the first and second casings 3 and 5 are gradually closed. Then, as shown in FIG. 16, the first, third, and fifth guide pins 31, 41, 52 are in the thickness direction of the hinge portion 6 in the first, third, and fifth guide holes 33, 43, 50, respectively. Move to the center. At the same time, the second and fourth guide pins 32 and 42 move away from the end portions on the left and right center sides of the second and fourth guide holes 34 and 44, respectively. At this time, the fifth guide pin 52 is further coupled to the connecting portion 51 of the first and third guide pins 31 and 41, and the fifth guide pin 52 is connected to the straight line between the first and third guide holes 33 and 43. The first and third guide pins 31 and 41 are surely linear with respect to the hinge part 6 without moving separately in an unstable direction by being inserted into the fifth guide hole 50 and restricting movement. The first housing 3 and the second housing 5 can be opened and closed smoothly. And if a flexible material is used for the connection part 51, it can connect so that expansion-contraction is possible, and when the shape of the 1st and 3rd guide hole is curvilinear, the space | interval of the 1st and 3rd guide pins 31 and 41 is sufficient. The opening / closing operation of the first housing 3 and the second housing 5 is smoothly performed even when the first housing 3 spreads. In this way, when the first housing 3 and the second housing 5 are opened and closed by the hinge portion 6, the hinge portion side corner portion 7 a of the first fixing plate 7 and the second fixing plate 8 The hinge part side corner part 8a is regulated so as to move along a linear locus with respect to the hinge part 6 without interfering with each other. For this reason, even if the first and second fixing plates 7 and 8 have a thickness, the hinge side corner portions 7a and 8a are kept in contact with each other.

  As shown in FIG. 3, when the opening / closing angle α of the first and second casings 3 and 5 is 90 ° (α = 90 °), the slide side walls 3d of the first and second casings 3 and 5 are provided. , 5d is in contact with the inner wall 28c in the sliding direction of the recess 28a for stopping, and the projections 28b provided on the first and second backlights 15 and 16, respectively. This restricts the subsequent slide movement of the first and second display modules 11 and 12. That is, at an angle smaller than this angle, the user is unlikely to use the screen while looking at the screen. Therefore, the first and second display modules 11 and 12 are restricted to move at the opening / closing angle α smaller than the first and second display modules 11 and 12. There is no inconvenience even if a gap occurs in the display area 20 between the second display modules 11 and 12. As described above, since the first and second display modules 11 and 12 need not be moved more than necessary by the stopper 28, the structure can be simplified.

  Next, the foldable portable terminal 1 is further closed as shown in FIGS. Since the shapes of the first and third guide holes 33 and 43 slightly expand toward the end portion, the hinge portion side corner portion 7a of the first fixing plate 7 and the second fixing plate 8 before the fully closed state. The hinge part side corner part 8a is separated and a gap is generated.

  When the folding portable terminal 1 shown in FIG. 6 is fully closed at 0 °, as shown in FIG. 17, the first, third, and fifth guide pins 31, 41, 52 are respectively the first, third, The fifth guide holes 33, 43, 50 are located at the lower end in the thickness direction of the hinge portion 6. The second and fourth guide pins 32 and 42 are returned to the ends on the left and right center sides of the second and fourth guide holes 34 and 44, respectively. As shown in FIG. 12, when fully closed, the hinge portion side corner portion 7a of the first fixed plate 7 and the hinge portion side corner portion 8a of the second fixed plate 8 are separated from each other to form a gap c.

  In this fully closed posture, the protective cover 60 covers the hinge 6 side ends of the first and second casings 3 and 5, so that the interiors of the first and second casings 3 and 5 are It is not exposed and looks good. Further, the first and second display modules 11, 12 whose sliding movement has been stopped by the stopper 28 are slightly pushed back by the protective cover 60 and fit in the protective cover 60.

  By adjusting the shape of the first to fourth guide holes 33, 34, 43, 44, and restricting the movement trajectory of each guide pin 31, 32, 41, 42, each of the surface side corners 7a, 8a The movement trajectory can be adjusted appropriately. For this reason, it is possible to restrict movement so that the front side corner portions 7a and 8a do not approach each other and do not interfere with each other while being in contact with each other without interfering with each other.

  By such an action of the hinge portion 6, the hinge portion side corner portion 7 a of the first fixed plate 7 and the hinge portion side corner portion 8 a of the second fixed plate 8 maintain a linear locus with respect to the hinge portion 6. Therefore, there is no need to leave a space between the corners on the surface side during opening and closing by restricting movement so as to leave a gap c when fully closed. Since the modules 11 and 12 slide in the casings 3 and 5 in accordance with the opening / closing operation of the first and second casings 3 and 5, the end of the display modules 11 and 12 on the hinge 6 side. The state which made the part contact is maintained. As a result, continuous images can be displayed.

  Therefore, when the first housing 3 and the second housing 5 are opened and closed by the hinge portion 6, the hinge portion side corner portion 7 a of the first fixing plate 7 and the second fixing plate 8 in the side view are viewed. By restricting the movement trajectory with the hinge side corner 8a, the first and second casings 3, 5 connecting the first casing 3 and the second casing 5 are connected. In the middle of opening and closing, the display devices 2 and 4 can be fully closed while the surfaces of the display devices 2 and 4 are continuous.

  Further, the display modules 11 and 12 are slidably moved in contact with each other inside the fixing plates 7 and 8 fixed to the casings 3 and 5, so that the first and second casings can be obtained. A large two-dimensional image in which the display area 20 is continuous can be displayed in the middle of opening and closing 3 and 5.

<3D display>
In step S06, the opening / closing direction detection unit 62 detects whether the user holds the foldable portable terminal 1 so as to open in the vertical direction or in the horizontal direction. In normal use, the first casing 3 is opened second with respect to the casing 5 in the vertical direction by being placed on a desk. When holding with left and right hands as in an electronic book, the first housing 3 and the second housing 5 are opened so as to open to each other. Here, the case of the direction of opening up and down will be described, but three-dimensional display can be performed in the same way when opening up and down. In the case of the direction of opening up and down, the parallax barrier extends up and down (that is, perpendicular to the axis of the hinge portion 6), and the left-eye image L and the right-eye image R are arranged side by side. The parallax barrier extends up and down (that is, parallel to the axis of the hinge portion 6) in the state of being held right and left, and the left-eye image L and the right-eye image R are arranged side by side.

  Next, in step S07, the opening / closing angle α detected by the opening / closing angle detector 63 is read. For example, when the opening / closing angle α is opened from 0 ° (0 <α <180 °), the display module controller 72 performs control so that only the first display module 11 performs three-dimensional display. On the other hand, in the second display module 12, no display is performed or two-dimensional display that does not disturb the three-dimensional display of the first display module 11 is performed.

  In step S08, the 3D display graphic engine 74 and the display module controller 72 change the size of the 3D image displayed in accordance with the open / close angle α.

  Thus, in step S09, the three-dimensional image is displayed larger as the opening / closing angle α increases.

  In step S07, the pop-out feeling or depth feeling of the three-dimensional display may be changed according to the opening / closing angle α. The principle of feeling this pop-out feeling or depth feeling will be briefly described. For example, by adjusting the shift interval between the left-eye image L and the right-eye image R captured by the left and right cameras, FIG. As shown in a), if the left and right images cross in front of the screen, the left and right eyes of the human brain cross in front of the screen and are recognized as a three-dimensional image as if they jumped out of the screen. . Also, as shown in FIG. 23B, if the left and right images cross behind the screen, the left and right lines of sight of the human brain cross behind the screen and the three-dimensional image is located at the back of the screen. Recognized as there is. Using this principle, control is performed such that when the opening / closing angle α is small, a three-dimensional image is displayed in a deeper position, and is displayed so as to pop out toward the near side as the opening / closing angle α increases.

  By controlling in this way, a small three-dimensional image is displayed when the opening / closing angle α between the first housing 3 and the second housing 5 is reduced, so that viewing can be performed without worrying about the surrounding line of sight. On the other hand, if it can be seen by the surrounding people, viewing can be performed with a greater sense of realism by gradually increasing the opening / closing angle α and viewing with a larger three-dimensional image.

  When the opening / closing angle α is 180 °, that is, during a full opening operation (α = 180 °), both the first display device 2 and the second display device 4 perform three-dimensional display. The image processor 73 performs the seam processing, and the three-dimensional display graphic engine 74 and the display module controller 72 cause the left-eye image L and the right-eye image R to be displayed in both the first display module 11 and the second display module 12. And are projected in a continuous manner up and down. Any switch liquid crystal 19 is turned ON. Thus, the most realistic 3D image using the two display modules 11 and 12 can be enjoyed. In addition, images can be viewed by a plurality of people around. In addition, since it is fixed in the fully opened state, a large three-dimensional image becomes easier to see if tilted appropriately.

  On the contrary, during the opening / closing operation (0 <α <180 °) from the fully open operation, the three-dimensional image is displayed smaller as the opening / closing angle α decreases, or the three-dimensional image decreases as the opening / closing angle α decreases. Appears behind the screen.

(Embodiment 2)
24 to 32 show a second embodiment of the present invention, which differs from the first embodiment in that the configuration of the hinge portion 106 is different. In the present embodiment, the same portions as those in FIGS. 1 to 23 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In other words, in the mobile terminal 101 of the present embodiment, the hinge unit 106 has the first casing so that the central axis comes to the mating surface when the first casing 3 and the second casing 5 are fully closed. 3 and the second casing 5 are formed with boss portions 106a and 106b, respectively. By inserting a hinge shaft 106c as a central axis into the left and right boss portions 106a and 106b, the first housing 3 and the second housing 5 are connected so as to be rotatable around the hinge portion 106. Although not shown, for example, if an urging mechanism is provided in the hinge shaft 106c, it can be easily held at a predetermined angle, and the opening / closing operation can be assisted.

  In the first embodiment, the stopper 28 includes the stop recess 28 a that is recessed in the slide side walls 3 d and 5 d of the first and second casings 3 and 5, and the protrusion 28 b of the first and second backlights 15 and 16. In this embodiment, the same stopper 28 as in the first embodiment may be provided. In the present embodiment, as shown in FIG. 31, the sliding movement of the first and second display modules 11 and 12 may be stopped by the stopper 28 around 50 °.

  Since other components are the same as those in the first embodiment, the description thereof is omitted.

  Next, the operation of the foldable portable terminal 101 according to the present embodiment will be described with a focus on differences from the first embodiment.

  First, also in the present embodiment, when the folding mobile terminal 1 shown in FIGS. 24, 25 and 29 is fully opened at 180 °, the first and second fixing plates 7 and 8 are completely continuous to form a single plate. Looks like a terminal.

  In the present embodiment, the first housing 3 and the second housing 5 perform only a rotating operation with respect to the hinge portion 106. The positions of the hinge side corners 7a and 8a of the first and second fixed plates 7 and 8 coincide with the center of the hinge shaft 106c.

  For this reason, as shown in FIGS. 29 to 32, the positions of the hinge-side corners 7a and 8a of the first and second fixing plates 7 and 8 are always set at the hinge shaft 106c even when changing from fully open to fully closed. Is consistent with the center of

  On the other hand, the first and second display modules 11 and 12 are urged so as to abut against each other toward the hinge portion 106 as in the first embodiment, respectively, and the first and second liquid crystals having the light guide element 25. Since the hinge side end portions of the panels 13 and 14 are always in contact with each other, the images are continuous.

  As shown in FIG. 31, when the closing angle reaches about 50 °, the projections 28b of the first and second backlights 15 and 16 come into contact with the inner wall 28c in the sliding direction, so that the first and second display modules 11 , 12 stops moving. For this reason, the first and second display modules 11 and 12 do not slide any further.

  When fully closed as shown in FIG. 32, the surfaces of the first and second fixing plates 7 and 8 are joined together. In the present embodiment, for example, the protective cover 60 is made of a stretchable material. For this reason, as in the first embodiment, the first and second display modules 11 and 12 whose sliding movement has been stopped by the stopper 128 are slightly pushed back by the protective cover 60 so as to be accommodated in the protective cover 60. In this case, the structure is simple and looks good. Note that the configuration of the protective cover 60 is not limited to this, and is not illustrated in detail. For example, the protective cover 60 is configured by three members whose cross section viewed from the side extends along the arcuate hinge portion 106, and is opened and closed. You may comprise so that it may overlap or leave. In this case, the back surface side can be flattened by retracting from the back surfaces of the first and second housings 3 and 5 when fully opened. Further, a mechanism for pushing back the first and second display modules 11 and 12 when fully closed may be provided separately.

  When a thin protective film is applied to the surfaces of the first and second fixing plates 7 and 8, the hinge shaft 106c and the hinge side corner 7a, What is necessary is just to adjust the positional relationship with 8a.

  Therefore, also in the folding portable terminal 101 according to the present embodiment, a large screen with a continuous display area can be displayed while the first and second casings 3 and 5 are being opened and closed.

  When performing the three-dimensional display, as in the first embodiment, when the opening / closing angle α is 0 ° <α <180 °, the size and depth of the three-dimensional image are changed in accordance with the opening / closing operation. When the angle α is 180 (α = 180 °), one large three-dimensional image can be enjoyed by two display modules.

(Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

  That is, in the above embodiment, the three-dimensional display is performed using the parallax barrier method, but the three-dimensional image is displayed by the lenticular method in which the left and right images are viewed using the light refraction of the kamaboko type lens. May be. However, in this case, since switching to the two-dimensional display is not possible, when the opening / closing angle α is 0 ° <α <180 °, a three-dimensional image can be displayed only by either the first display module 11 or the second display module 12. The other is not displayed, and the three-dimensional image may be continuously displayed by both modules when the open / close angle α is 180 ° (α = 180 °). Further, a three-dimensional display using glasses may be used.

  In the above embodiment, the urging member is the leaf spring 27. However, a compression coil spring is provided at the same position as the leaf spring 27, and the first and second display modules 11 and 12 are pressed against the hinge portion 6 side. Alternatively, the projection 28b may be pulled toward the hinge part 6 by a tension coil spring, and the first and second display modules 11 and 12 may be pulled toward the hinge part 6. Also in this case, since the first and second display modules 11 and 12 are always urged by the compression coil spring or the tension coil spring and pressed against each other with an appropriate force, continuous images can be displayed during opening and closing with a simple configuration. It becomes possible.

  In each of the above embodiments, the stopper 28 includes the stop recess 28a that is recessed in the slide side walls 3d and 5d of the first and second casings 3 and 5, and the protrusion 28b of the first and second backlights 15 and 16. However, the present invention is not limited to this. For example, as shown in FIG. 33, as a stopper 128, a locking projection 128a protruding rightward on the right side of the hinge 106 side end of the first backlight 15 and a hinge portion of the second backlight 16 are provided. A locking protrusion 128a protruding in the left direction may be provided on the left side of the end portion on the 106 side. An L-shaped projection 128b is provided on the first housing 3 so as to project toward the hinge portion 106 in correspondence with the right locking projection 128a, and a second housing is formed in correspondence with the left locking projection 128a. An L-shaped projection 128b is provided on the body 5 so as to project toward the hinge portion 106 side. The second housing 5 facing the right L-shaped projection 128b has a contact preventing recess 128c recessed so as to accommodate the L-shaped projection 128b, and faces the left L-shaped projection 128b. The first housing 3 is provided with a contact preventing recess 128c so that the L-shaped projection 128b is accommodated. Also in this stopper 128, the effect similar to the stopper 28 of each said embodiment is acquired. The stopper 128 does not necessarily have to be provided with the locking projections 128a at the hinge 106 side ends of the first and second backlights 15 and 16, and the first and second casings 3 and 5 are not provided. When the opening / closing angle α is equal to or smaller than the predetermined angle, the L-shaped protrusion 128b abuts against the hinge 106 side ends of the first and second backlights 15 and 16, and the first and second display modules 11 and 12 slide. You may comprise so that a movement may be controlled. In this case, if the L-shaped projection 128b is configured to be pushed in, the protective cover 60 can be pushed in when fully closed.

  In each of the above embodiments, the first and second display modules 11 and 12 are provided with the first and second liquid crystal panels 13 and 14. However, the present invention is not limited to such a liquid crystal display device, but a PDP, an organic EL display device, An electrophoretic display device may be provided. Also in this case, if a similar light guide element 25 is provided, continuous screen display is possible.
