Description

  The present invention relates to a portable display device. The display device of the present invention is also intended for a device having a function as a computer, a television receiver, a telephone function, an automatic ticket gate, a mobile communication function such as ETC, RFID, DSRC, etc. It also means a device.

  In recent years, portable information processing apparatuses such as portable personal computers and cellular phones have become increasingly sophisticated. However, personal computers are not yet excellent in portability in terms of weight and size. In addition, mobile phones have problems such as small screens that are difficult to see and poor operability.

  On the other hand, in the flat display, the colored particles provided in the microcapsule are displayed by being displaced or inverted by an electric field, and the display state is maintained when the electric field is not applied. There is an organic EL (organic LED) that emits light by being injected into it and recombined. The following patent documents 1 to 3 are documents related to electronic paper, and the following patent documents 4 to 9 are documents related to organic EL. The following Patent Documents 10 to 12 are documents relating to folding and storage of the display.

JP-A-11-327470 USP 4,143,103 USP 4,126,854 JP 2002-305077 A JP 2002-260855 A Japanese Patent Laid-Open No. 10-340781 Japanese Patent Laid-Open No. 10-237439 Japanese Patent Laid-Open No. 10-289785 JP 2003-147345 A JP 2002-300506 A JP 2004-32196 A JP-A-7-230250

  However, thin-film flat displays have been developed, but these are made on a glass substrate, and flexibility is not considered at all. The technique described in Japanese Patent Application Laid-Open No. 7-230250 of Patent Document 12 improves the portability of the information processing apparatus by dividing the display and folding or assembling it. However, in the method of assembling divided panels using liquid crystal or the like, there is necessarily a frame that does not have pixels around each panel, so even if it is expanded on the entire screen, the frame line is difficult to see on the screen. It becomes a screen. In addition, the technique of Japanese Patent Application Laid-Open No. 2004-32196 of Patent Document 11 has proposed a display of a method of winding a liquid crystal sheet when stored, but has a rigidity that can be held flat when the liquid crystal sheet is spread on a plane, The liquid crystal sheet is required to have two characteristics that contradict the softness for winding in a columnar shape, and it can be said that the feasibility is poor.

Therefore, an object of the present invention is to improve the portability and operability of the information display device by allowing the screen to be stored compactly.
Another object of the present invention is to provide an information display device which is a portable information processing device having a screen that can be stored compactly and can be widely deployed when used.

A computer system such as a CPU 40 for information processing, a DSP 41 that is an arithmetic unit for screen control, a ROM 42 and RAM 43 for storing data, and a keyboard 22 for inputting data is provided. Further, a thin film flat display 30 on which a display image is created by the DSP 41, a thin film flat display 18 controlled by the CPU 40, a television receiver circuit 50, an audio / data transmitting / receiving circuit 51, a speaker 52 connected to the circuit 51, and A microphone 53 is provided. In addition, a USB terminal 25 and a LAN terminal 26 for performing wired data communication with the outside are connected to the CPU 40, and an audio and data communication antenna 36 is connected to the audio / data transmission / reception circuit 51 to receive TV radio waves. The antenna 56 is connected to the television receiver circuit 50.

  The mounting location of each of these devices will be described. The computer system such as the CPU 40, DSP 41, ROM 42, and RAM 43, the television receiver circuit 50, and the audio / data transmission / reception circuit 51 are provided as an integrated circuit 70 in the main bone 12a. The speaker 52 is provided at the upper end of the main bone 12a, and the microphone 53 is provided at the base of the main bone 12a.

In addition, the main bone 12a is provided with a digital camera and a digital sound recorder (not shown).

  In this embodiment, the fan surface 14 is a thin film organic EL display formed on a thin flexible resin film. As shown in FIG. 4, the organic EL display has a cathode 110, an electron injection layer 112, an electron transport layer 114, a hole blocking layer 116, and a light emitting element, which are made of Mg, Li alloy or the like in this order on a thin film 100. A layer 118, a hole transport layer 120, a hole injection layer 122, and an anode 124 made of ITO (indium tin oxide) are provided. The cathode 110 is a large number of strip-shaped (parallel to the paper surface) electrodes, and the anode 124 is a large number of strip-shaped (perpendicular to the paper surface) electrodes. A transparent resin film 126 is formed on the entire surface of the organic EL display to protect the display. In FIG. 4, only two pixels are displayed. These layers are formed by a vacuum evaporation method using a metal mask. Further, it is possible to use a thin film forming method using ions or radicals using a plasma of a source gas. In addition, Japanese paper can be used instead of the thin film 100.

  The organic material may be a low molecular organic material or a high molecular organic material. In the case of using a low molecular weight organic material, it is formed by a vacuum deposition method. However, in the case of a high molecular weight organic material, after the molten polymer is dropped on the substrate, the substrate is rotated to be uniform on the substrate. A spin coating method for forming a thick film can be used. When a polymer organic material is used, an organic EL display can be configured with only the light emitting layer or only the light emitting layer and the hole injection layer.

  In order to achieve full color, an organic material to which dyes of R, G, and B are added may be separately deposited for each display unit using a mask (shadow mask method). For example, if FIG. 4 is a full-color display, only two of the R, G, and B light emitting regions are illustrated in FIG. In the case of a full-color display device using a polymer material, a method of forming a film at a predetermined light emitting point by using an organic substance to which dyes of R, G, and B are added as a liquid and by ink jetting is used. An ink printing method can also be used.

  As the material of the light emitting layer 118, a metal complex, for example, a heavy metal ion such as iridium or platinum, or a rare earth metal ion such as terbium, europium, or cerium is arranged at the center, and an organic substance (ligand) is disposed around the metal complex. What was combined can be used.

  Since other organic EL display materials and manufacturing methods thereof are described in detail in Patent Documents 4 to 9 described above, the methods described therein can be used. On the other hand, the thin film flat display used in the information display device of the present invention is characterized in that an organic EL thin film flat display is formed on a flexible flexible thin film 100. Therefore, for the detailed explanation of the production of the organic EL display, it is sufficient to list Patent Documents 4 to 9 describing the production method, thereby satisfying the enablement requirement of the specification.

  In FIG. 1, the screen is designed in a rectangular area indicated by area A. In portions other than the rectangular area A, signal lines 32 and 34 for connecting the master bones 12a and 12b and the electrodes of the rectangular area A and controlling the display of pixels are formed. With this configuration, an image is displayed in the image area A under the control of the DSP 41. Further, the CPU 40 detects an operation input from the keyboard 22 and executes a process corresponding to the operation. In addition, an antenna 36 is provided in the main bone 12b, and it is possible to transmit and receive audio and data with respect to the outside. Further, the television signal can be received by the antenna 56 formed of the middle bone, and the video can be displayed in the image area A.

  Further, a keyboard 71 may be provided at the root of the middle bone 15. In this case, a keyboard is formed by forming a recess in the surface of the middle bone 15 so that the surface of the keyboard 71 does not protrude from the surface of the middle bone 15 and providing a membrane switch or the like in the recess. desirable.

  Further, as shown in FIG. 5, the root portions 150a and 150b of the middle bones 15a and 15b are thickened so that the folded fan surface 14 is sufficiently stored between the adjacent middle bones 15a and 15b. It is desirable to form thin portions 151a and 151b to which 14 is joined. Thereby, opening and closing of the fan surface 14 can be made smooth. Moreover, when the fan surface 14 is unfolded, it has a fan shape as shown in FIG. 1, but the upper side of the fan surface 14 may be a straight line when unfolded. That is, it may be formed such that the length in the central direction of the fan surface increases from the center of the fan surface 14 toward both ends. In this way, when the fan surface 14 is expanded, a large rectangular area can be obtained, and the area of the image area A can be increased. Further, although the fan surface 14 itself is an organic EL flat display, a rectangular organic EL display may be joined to the screen area A on the fan surface 14 so that it can be folded together with the fan surface 14.

  According to the information display device 10 of the present embodiment, the screen can be folded and convenient for carrying, and when used, the screen can be developed in a flat shape, so that a large screen can be obtained and the usability is improved. First, the apparatus of this embodiment can be used as a computer capable of Internet communication. Second, it can be used as a television receiver. Third, it can be used as a mobile phone. Fourth, the IC tag 60 is used as an automatic settlement at a ticket gate of a transportation facility, an automatic settlement at a bank account, an electronic money card, a Juki card, a card for an automatic ticket gate of a transportation facility, a distribution tag, or the like. It is possible. Fifth, it can be used for imaging with a digital camera, recording with a digital recorder, and the like, and the data can be easily edited using a large screen. Thus, this apparatus can be used as an intelligent terminal apparatus with improved portability and usability.

  In this embodiment, an organic EL flat display is joined to the mountain of the fan surface 14 in the first embodiment. 6 is a perspective view, and FIG. 7 is a cross-sectional view taken along the arc of FIG. As shown in FIG. 6, the fan-shaped organic EL flat display 80 manufactured by the above-described method is provided so as to be bonded to all the ridge lines 141 a of the fan surface 14. The image area A is the same as that in the first embodiment. The rear surface of the organic EL flat display 80 is connected to the valley 141 b of the fan surface 14 by the thread 81. The thread 81 may be provided at a plurality of locations along the length direction of the middle bone 15. The yarn 81 is in a state of being stretched in a straight line with the fan surface 14 being developed in a flat shape. When the fan surface 14 is folded, as shown in FIG. 8, the valley 141b is deepened. Therefore, the thread 81 pulls the organic EL flat display 80 from the back surface in the direction of the valley 141b. As a result, the organic EL flat display 80 is folded toward the valley 141b in the initial stage of folding, and is smoothly folded into the valley portion of the fan surface 14 by the subsequent folding operation.

  As shown in FIGS. 9 and 12, the information display apparatus of this embodiment is provided with a case 90 as a main body, and a keyboard 22 is formed on the upper surface of the case 90 as shown in FIG. . In the case 90, the same devices as those mounted in the main bones 12a and 12b shown in the first embodiment are arranged. These devices are collectively indicated by 91 in FIG. As shown in FIG. 10, substrates 92 made of a large number of strip-shaped rigid resins are arranged adjacent to each other in a flat plate shape. A rectangular organic EL flat display 93 is joined on the flat plate.

  Moreover, as shown in FIG. 11, the recessed part 92a and the convex part 92b are formed in the side surfaces 921 and 922 of two adjacent board | substrates 92 and 92, respectively. The concave portion 92a and the convex portion 92b are arranged in an arc shape so that the rotation is smooth when the substrate is rotated with the line of intersection between the substrate 92 and the substrate 92 on the organic EL flat display 93 side inward. It is configured. Due to the engaging action of the concave portions 92a and the convex portions 92b, the organic EL flat display 93 is difficult to bend upward (convex in the anti-vertical direction) in a state where the organic EL flat display 93 is unfolded. Thereby, the organic EL flat display 93 becomes stable in a planar shape at the time of use, and usability is improved.

  Further, the organic EL flat display 93 is housed in the case 90 by winding the organic EL flat display 93 around the rotation shaft 96 with the rotating force of the motor 95 with the organic EL flat display 93 as an inner surface. A pair of rollers 94a and 94b are provided at the entrance of the case 90, and the substrate 92 and the organic EL flat display 93 bonded thereto are sandwiched between the pair of rubber rollers 94a and 94b to provide elasticity. It is configured to grant. With this configuration, when wound, the engagement between the concave portion 92a and the convex portion 92b of the substrate 92 is easily relaxed. When the organic EL flat display 93 is developed in a flat shape, the concave portions 92a and the convex portions 92b of the substrate 92 are engaged by the pressing force of the rollers 94a and 94b.

  Parts having the same functions as those in Example 1 are denoted by the same reference numerals. In this embodiment, when the fan surface 14 is unfolded, it is configured to be a plane instead of a wavefront. The outer peripheral portion 201 and the inner peripheral portion 202 of the fan surface 14 are concentric arcs centering on the penetrating shaft 16 constituting the main part. And all the broken lines 203 of the fan surface 14 are comprised in the direction which goes to the penetration axis | shaft 16. As shown in FIG. By comprising in this way, it can be made into a plane when the fan surface 14 is expand | deployed. As a result, the image displayed in the image area A becomes easier to see. Other configurations are the same as those in the first embodiment.

  The present embodiment has the same configuration as that of the third embodiment. A large number of strip-shaped rigid substrates 92 are arranged adjacent to each other in a flat plate shape, and a rectangular organic EL flat display 93 is bonded on the flat plate. Magnets 97a and 97b are fixed at two locations on the side surfaces adjacent to each other of the adjacent substrates 92 made of resin. These magnets 97a and 97b are embedded in recesses formed in the opposing side walls of the respective substrates 92 and 92. The surfaces of the side walls of the substrates 92 and 92 and the surfaces of the magnets 97a and 97b constitute the same surface, respectively. These opposing magnets 97a and 97b are composed of magnetic poles having different opposing surfaces, and are configured such that an attractive force acts on each other. As a result, when the organic EL flat display 93 is deployed outside the case 90, the plurality of substrates 92 are held flat by the action of these magnets. That is, a series of the plurality of substrates 92 can be flat and can be bent neither upward nor downward.

  When the organic EL flat display 93 is wound inside the case 90, the magnets 97a and 97b are bent in a direction perpendicular to the attractive force by the action of the rollers 94a and 94b and the rotating shaft 96 shown in FIG. Because the force acts, these magnets can easily bend against the attractive force. That is, since the magnet force does not reach the direction orthogonal to the magnet attractive force, the directions of the two magnets 97a and 97b can be easily changed. The substrate 92 may be made of a magnetic material such as stainless steel instead of resin. If it does so, even if the magnetic force of magnet 97a, 97b is weak, the joining force between adjacent board | substrates will improve. Further, although the magnets 97a and 97b are used for a part of the substrate, they may be attached to the entire side wall of the substrate. Further, an anisotropic rare earth bonded magnet (plastic magnet) may be used as the magnet. In this case, a small amount of light weight and a large holding force can be obtained.

  The present embodiment has the same configuration as that of the third embodiment. In this embodiment, the organic EL flat display 99 is configured as a shape memory resin film 100 instead of the thin film resin film 100 of FIG. The organic EL flat display 99 does not have the substrate 92. Then, as shown in FIG. 15, the two rollers 98a and 98b and the rotating shaft 96 are heating rollers. A nichrome wire, a lamp, or a Peltier effect element can be used for this heating. In this embodiment, the lamps 85 are used to heat the two rollers 98a and 98b, the rotating shaft 96, and the thin film resin film 100. When unfolding or winding up the organic EL flat display 99, the shape memory resin film 100 is heated to the transition point temperature by heating the rotating shaft 96 and the rollers 98a and 98b. Then, the shape memory resin film 100 is softened by heating, and easily changes its shape along the circular shape of the roller 98a and the rotating shaft 96. In this manner, the shape memory resin film 100 can be wound around and stored around the rotation shaft 96 while changing the shape of the shape memory resin film 100.

  Further, when the shape memory resin film 100 is extended, similarly, the shape memory resin film 100 is easily deformed by heating the rotating shaft 96 and the rollers 98a and 98b, and is flattened by human power. Can be deployed. The shape memory resin film 100 is developed into a flat plate shape and cooled to hold this state. Due to this action, the organic EL flat display 99 can be a fixed flat plate, thereby greatly improving the visibility of the image and facilitating handling when the display is used. Further, at the time of storage, the organic EL flat display 99 easily changes its shape, so that winding becomes easy.

  Instead of the shape memory resin film 100, a thin plate of shape memory alloy may be used. When a thin plate of shape memory alloy is used, the organic EL flat display 99 can be easily developed and stored because it is flexible at room temperature. And it can be set as the planar shape which the thin plate of the shape memory alloy memorize | stored by supplying with electricity and heating in the state which expand | deployed the organic electroluminescent flat display 99. FIG. Thereafter, even if the current is cut off and the temperature drops to room temperature, the shape memory alloy thin plate maintains the planar shape unless an excessive external force is applied, so that the planar retainability is improved. Therefore, it is possible to provide a flat image that is easy to see. When the shape memory alloy is heated by the rotating shaft and the roller as described above, the shape memory alloy is heated only when it is developed on a plane. Further, in the case of adopting a configuration in which a heater is provided on the back surface of the shape memory alloy thin plate and power is supplied to the heater, the shape memory alloy thin plate is heated in a flat shape and then heated.

  Instead of the take-up and storage of the sixth embodiment, this embodiment uses a folding storage. As shown in FIGS. 16A and 16B, inside the case 90, there are four shaft-like fixed rollers 87, three shaft-like moving rollers 88, and 3 for urging the moving rollers 88 in the X-axis direction. Two springs 89 and a heating device 86 are provided. The organic EL flat display 99 is alternately engaged with each roller as shown in the figure. The moving roller 88 is guided by a groove (not shown) formed in the X-axis direction on the inner wall of the case 90, and is arranged to be movable in the X-axis direction by the biasing force of the spring 89. The left end of the organic EL flat display 99 is bonded to the leftmost fixed roller 87. Thereby, when the organic EL flat display 99 is developed, the organic EL flat display 99 is configured not to move in the developing direction. The heating device 86 is an arbitrary heating device such as a heater or a lamp, but is disposed on the inner wall at the upper end of the case 90. FIG. 16-A shows the storage state, and FIG. 16-B shows the unfolded state. When the heating device 86 is energized and the organic EL flat display 99 is heated, the thin film made of the shape memory resin as the base softens, and the urging force of the spring 89 causes the three moving rollers 88 to move in the X-axis direction. Move to. Thereby, the organic EL flat display 99 is folded in a bellows shape. Thereafter, when the energization of the heating device 86 is interrupted, the organic EL flat display 99 is cooled and maintains the shape of FIG.

  In use, when the organic EL flat display 99 is developed into a flat surface, the heating device 86 is energized to heat and soften the organic EL flat display 99. In this state, when the organic EL flat display 99 is pulled to the outside by holding the handle 79 provided at the right end of the organic EL flat display 99 by human power, the moving roller 88 resists the biasing force of the spring 89. Move in the axial direction. Next, when the energization of the heating device 86 is interrupted, the organic EL flat display 99 is cooled and hardened, and the developed flat shape is maintained as shown in FIG. 16-B. At this time, the degree of curing of the thin film is superior to the biasing force of the spring 89, and the moving roller 88 does not move in the X-axis direction. Thereby, since the organic EL flat display 99 is fixed in a flat state, a clear flat image can be obtained.

  Further, using a shape memory alloy for the thin film, the state stored in the bellows shape of FIG. At room temperature, this shape memory alloy is soft, and as shown in FIG. 16-B, the organic EL flat display 99 can be developed in a flat shape. Since this planar state is maintained unless an excessive force is applied, the organic EL flat display 99 maintains the planar state, so that a clear planar image can be obtained. At the time of storage, when the heating device 86 is energized, it returns to the stored shape of FIG. 16-A and the organic EL flat display 99 is stored in the case 90.

  Conversely, the shape memory state at a high temperature may be a developed planar shape as shown in FIG. In this case, when the organic EL flat display 99 is developed on a plane, the stored shape can be restored and developed on the plane by heating the heating device 86. Then, the organic EL flat display 99 is used while the heating device 86 is kept energized or is turned off and at room temperature. In the case of interrupting energization, a stopper for stopping the movement of the moving roller 88 may be provided so that the biasing force of the spring 89 in the X-axis direction does not act on the moving roller 88. That is, it is configured to be able to advance and retreat from the inner side wall of the case 90, and the recess formed on the end surface of the moving roller 88 and the stopper are engaged. When storing, do not heat. The engagement between the stopper and the moving roller 88 is released, and the moving roller 88 is moved in the X-axis direction by the urging force of the spring 89, so that the organic EL flat display 99 has a bellows shape as shown in FIG. Can be folded and stored.

  Instead of the thin film 100 of Examples 1, 2, and 4, a shape memory resin film or a shape memory alloy thin film may be used. Then, the fan surface may be heated by providing heater wiring on the fan surface 14 and energizing it. Further, the fan surface 14 can be heated by energizing the middle bone 15 as a heater. As a result, the fan surface 14 can be extended to a memorized plane by energizing and heating the fan surface 14 in a state of being flattened by human power, and the fan surface 14 can transition from a corrugated shape to a flat surface. . That is, the fold of the fan surface 14 disappears. In this state, energization is stopped to stop heating, and the fan surface 14 is used as a display. Even if the temperature falls, unless the external force is applied, the fan surface 14 maintains a certain flat shape unless the fan surface 14 is folded, and there is no obstacle to using the fan surface 14 as a display. .

  Next, when the use is finished and the fan surface 14 is stored in a bellows shape, the fan surface 14 may be folded by applying an external force to the main bones 12a and 12b so as to store the fan surface 14 of the fan. Since the shape memory resin film and the shape alloy thin film are flexible at room temperature, they can be easily folded. In this manner, a planar shape in which the waveform disappears when the fan surface 14 is developed can be obtained, and the image quality can be improved.

  Further, when the thin film 100 is used as a shape memory resin and its superelasticity is used, the fan surface 14 is developed in a flat shape so that the waveform disappears in a heated state, and then cooled to develop the flat shape. The thin film 100 is solidified and fixed. At the time of storage, the fan can be stored by folding it in a bellows shape in a heated state. In this way, it is possible to solve the problems of bending storage and flatness during deployment.

  The use modes such as the shape memory alloy, the shape memory resin, the shape memory alloy fiber, and the shape memory resin fiber described above are merely examples, and are not limited to this use mode. According to the characteristics of these functional materials, it is only necessary to realize a transition between two shapes of bending and plane.

  The present invention can be used as a portable display device or intelligent terminal device.
