It is arranged.

  The display panel 300 is formed in a substantially thin rectangular shape that is long in the left-right direction, which is the horizontal direction, and is configured to be able to bend and deform at least in the left-right direction. Examples of the display panel 300 include a flexible and bendable configuration such as a liquid crystal display panel, an electroluminescence (EL) panel, and an electrophoretic display panel. Furthermore, the display panel 300 is formed in a state in which the flexibility is increased according to the peripheral edge, that is, the display panel 300 is easily bent. As this configuration, for example, as shown in FIG. 2, a configuration in which the thickness dimension is reduced according to the peripheral edge, a configuration in which the thickness dimension is soft according to the peripheral edge, or a reinforcing material (not shown) is provided so as to increase rigidity according to the center. For example, it can be provided. The display panel 300 has a display surface of the display panel 310 so that the display panel 300 can be accommodated in the accommodation space 213 on the support portion 260 provided to be able to advance and retreat in the accommodation space 213 of the armrest portion 210 of the chair 200. The backrest 230 is supported so as to be substantially opposed to the backrest surface 231. Further, as shown in FIGS. 2 and 3, the support portion 260 has a variable distance between the display surface of the display panel 300 and the user X sitting on the chair 200 serving as a reference point. Moving means 261 such as an electric motor for moving in the direction is provided. The moving means 261 is driven by a control signal output from the reproduction processing device 500 in response to an input operation of the operation means 510 such as an adjustment knob (not shown) of the reproduction processing device 500 provided in the armrest portion 210, for example. 300 is moved back and forth.

  As described above, the speaker 400 is disposed on the backrest 230 of the chair 200 so as to be able to advance and retreat. The speaker 400 is connected to the reproduction processing device 500, and is advanced / retreated from the backrest unit 230 by a control signal from the reproduction processing device 500, and the sound data output from the reproduction processing device 500 is output as sound.

  The reproduction processing device 500 is disposed on the chair 200 and outputs or reproduces image data as a video or outputs or reproduces sound data as a sound. The reproduction processing device 500 includes the operation unit 510, the reproduction processing unit 520, and the display adjustment device 530 described above.

  The operation means 510 has various operation buttons and operation knobs (not shown) that are arranged to face the upper end surface of the reproduction processing apparatus 500 and are operated for input. The contents of the input operation of these operation buttons and operation knobs are setting items such as the setting of the operation contents of the reproduction processing apparatus 500, for example. Specifically, setting of forward / backward movement of the display panel 300 and the speaker 400, setting of reproduction start / stop request of sound data and image data, setting of sound characteristics of reproduced sound, display of video reproduced as a screen display Examples of setting of characteristics can be given. Then, the operation unit 510 appropriately outputs and sets a predetermined signal to the reproduction processing unit 520 and the display adjustment device 530 by an input operation of setting items. The operation unit 510 is not limited to an input operation such as an operation button or an operation knob, and various setting items such as an input operation using a touch panel provided on the display panel 300 and an input operation using voice can be set and input.

Here, the sound data is data output as sound from the speaker 400, such as sound data or music data. The image data is data that is output as a video image on the display panel 310, such as image data or video data. The reproduction processing unit 520 acquires, for example, image data and sound data input via a drive operation control provided in the armrest unit 210 or a terminal (not shown) provided in the chair 200, and the display panel 300. Then, the screen output or the sound output from the speaker 400 is performed. Here, as the drive, for example, image data and sound data stored in various recording media such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a magnetic disk, a magneto-optical disk, and a memory card are read and output as appropriate. Either configuration can be used. As a configuration for acquiring image data and sound data, for example, any configuration in which data acquired based on broadcast waves, data is acquired via a network such as the Internet or an intranet, and appropriately processed and output can be used. In addition, the reproduction processing unit 520 operates the moving unit 261 and moves the display panel 300 and the speaker 400 forward and backward according to a setting input signal corresponding to the input operation by the operation unit 510.

  The display adjustment device 530 bends and deforms the display panel 300 so that the display surface side is concave. As shown in FIGS. 2 and 3, the display adjustment device 530 includes a distance sensor 531 as a distance recognition unit, a bending unit 532, and a calculation unit 533 as an out-of-range region recognition unit.

  The distance sensor 531 is, for example, a clearance sonar, and is disposed at the approximate center of the upper edge of the display panel 300. This distance sensor 531 is connected to the calculation means 533, measures the separation distance between the user sitting on the chair 200 and the display surface of the display panel 300, and outputs a signal related to the separation distance as a measurement result to the calculation means 533. To do.

  For example, the bending unit 532 is disposed on the support portion 260 that supports the display panel 300 and is connected to the calculation unit 533, and the display panel 300 is bent under the control of the calculation unit 533. As shown in FIG. 3, the bending means 532 includes a pair of drive parts 532A and a link mechanism part 532B as a moving means. For example, a solenoid or an electric motor is used as the driving unit 532A, and the driving unit 532A is symmetrically disposed in the left-right direction at the center of the display panel 300 on the back surface of the display panel 300. The link mechanism portion 532B includes a moving portion 532B1 that is long in the left-right direction and is disposed in the driving portion 532A so as to be movable in the left-right direction by driving of the driving portion 532A. One end of a longitudinal urging portion 532B2 is rotatably connected to a distal end portion in the left-right direction of the moving portion 532B1. Further, the tip of the urging portion 532B2 is pivotally connected to the approximate center of the vertically extending reinforcing member 532B3 disposed along the left and right edges of the display panel 300. Has been. The link mechanism unit 532B moves the moving unit 532B1 in the left-right direction with respect to the driving unit 532A by driving of the driving unit 532A whose driving is controlled by the calculation unit 533, and the biasing unit 532B2 by the movement of the moving unit 532B1. Thus, the reinforcing member 532B3 side rotates in the front-rear direction. Due to the operation of the bending means 532, due to the difference in flexibility in the horizontal direction of the display panel 300, the horizontal edge of the display panel 300 is bent in the front-rear direction and bent in a state where the radius of curvature decreases along both edge sides. Is done.

  The calculation means 533 is a CPU (Central Processing Unit), for example, and a stereoscopic field at the reference point G based on a signal related to the separation distance output from the distance sensor 531 and a preset size of the display surface of the display panel 300. An operation for recognizing the area of the display surface located outside the range as the out-of-range area is performed. As shown in FIG. 4, the out-of-range region to be calculated is a region in which the center angle in the left-right direction is located outside the range of 60 degrees around the reference point G that is outside the stereoscopic field of the user X. is there. Specifically, the value of the tangent at 60 degrees with respect to the separation distance D (D × tan 60 °), that is, the distance from the center of the display panel 310 that is the center in the facing direction of the user X and the display panel 310 to the left and right direction. The outside is the out-of-range region.

  Then, the calculation means 533 performs processing for bending the out-of-range area to the reference point G side by the bending means 532 by the calculation for recognizing the out-of-range area of the display surface, that is, the moving part 532B1 of the link mechanism part 532B Control is performed to drive the drive unit 532A so as to advance to a predetermined amount. Specifically, as shown in FIG. 4, when the display panel 300 is at a position A away from the reference point G, the entire surface of the display panel 300 is within the stereoscopic field range. 300 is not bent. At the position B where the display panel 300 approaches the reference point G, both side portions of the display panel 300 in the left-right direction are out-of-range regions outside the stereoscopic field range. Accordingly, at least the out-of-range region is bent toward the reference point G, that is, the driving unit is driven to a state where the moving unit 532B1 of the link mechanism unit 532B advances a predetermined amount in the left-right direction corresponding to the separation distance, The left and right ends of the display panel 300 are bent toward the reference point G so that the radius of curvature decreases along both ends of the display panel 300. Furthermore, at the position C where the display panel 300 approaches the reference point G, the out-of-range region outside the stereoscopic field range becomes wide. As a result, the driving unit 532A is driven so that the moving unit 532B1 of the link mechanism unit 532B further advances by a predetermined amount in the left-right direction corresponding to the separation distance D, and the both end sides of the display panel 300 are moved closer to the reference point G side. Control to bend. In this way, the amount of biasing the both end sides of the display panel 300 toward the reference point G side is controlled corresponding to the separation distance D, that is, the both end sides are set to the reference point G side in a distance relationship inversely proportional to the length of the separation distance D. If the display panel 300 is controlled to be biased, the display panel 300 is formed so as to be easily bent along both end sides. Therefore, the display panel 300 is bent so that the radius of curvature decreases along both end sides. For example, according to the separation distance D, the movement amount of the moving unit 532B1 and the driving time of the driving unit 532A which are set in advance are recognized, and the driving unit 532A is driven to a state where the moving amount and the driving time are reached. Corresponding to the length of the separation distance D, the amount of movement of both ends of the display panel 300 toward the reference point G is changed, and the bent state is changed.

(Operation of playback system)
Next, the operation of the playback system 100 will be described.

  First, when the user X sitting on the chair 200 turns the armrest plate portion 212 of the armrest portion 210 to open the upper surface of the regeneration processing device 500 disposed in the accommodation space 213 and turns on the power, the regeneration processing device. 500 performs the initial setting and enters an input standby state. In this state, when the user X sets and inputs a reproduction request for various data such as predetermined sound data and image data by an input operation with the operation unit 510, the speaker 400 is placed on the back when the reproduction processing unit 520 is sound data. In the case of image data, the display panel 300 is advanced to a position facing the backrest portion 230. Further, the reproduction processing unit 520 acquires the requested data from a predetermined storage location or distribution source, for example, reads it from a drive, acquires it by processing a broadcast wave, or acquires it via a network. To process. Then, a reproduction process for outputting the processed sound data as sound from the speaker 400 is performed, and a reproduction process for displaying the processed image data on the display panel 300 is performed.

  Further, when the image data in the reproduction process is displayed on the screen, the distance sensor 531 measures the separation distance D and outputs the measurement result to the calculation means 533. Thus, the calculation means 533 performs a calculation for recognizing an out-of-range region that is outside the stereoscopic field range of the display surface of the display panel 300 based on the separation distance D and the preset size of the display panel 300. . Then, the calculation unit 533 appropriately drives the drive unit 532A based on the separation distance D. For example, the drive unit 532A is appropriately driven according to the length of the separation distance D. By driving the driving unit 532A, the moving unit 532B1 of the link mechanism unit 532B moves a predetermined distance in the left-right direction corresponding to the length of the separation distance D, and the reinforcing member 532B3 side of the biasing unit 532B2 rotates a predetermined amount in the front-rear direction. The both ends of the left and right direction of the display panel 300 are urged toward the reference point G by a predetermined amount, and the both ends of the display panel 300 in the left and right direction are bent by a predetermined amount.

  In a state where the display panel 300 is bent, an image in an out-of-range region outside the stereoscopic field range on the display panel 300 is visually recognized in a state where it is felt close to the user X. That is, the user X feels that the viewing distance of the image in the region outside the stereoscopic field range is closer to the viewing distance of the image in the region within the stereoscopic field range. For this reason, the user X becomes a sensation wrapped in video, and a sense of realism is obtained.

(Operational effects of the playback system)
As described above, in the above-described embodiment, a state in which an image of an area that is visually recognized outside the stereoscopic field range at the reference point G is a viewing distance that is closer to the visual distance in the image of the area that is recognized within the stereoscopic field range. Is controlling. For this reason, since the image of the area that is visually recognized by the user X outside the range of the stereoscopic field of view is felt nearby, the width dimension in the vertical direction at the both ends in the left-right direction is a substantially drum shape that becomes wider according to both ends. As a result, the user can get a feeling of being wrapped in the video, and the video can be focused easily and clearly, thereby improving the sense of reality.

  The distance between the display surface of the bendable display panel 300 and the visual reference point G for the user X is set as a distance closer to the visual recognition of the image of the region visually recognized outside the stereoscopic field of view. The distance D is measured by the distance sensor 531. Based on the separation distance D and the size of the display surface of the display panel 300, the out-of-range region located outside the stereoscopic field range of the display surface has a curvature radius smaller than the curvature radius in the stereoscopic field range as another region. In the state, the outside area outside the stereoscopic field range is bent toward the reference point G by the bending means. For this reason, the structure from which a sense of reality is obtained is easily obtained.

  In addition, as a region outside the stereoscopic field range, the calculation means 533 recognizes the region as a region outside the center angle within the range of 60 degrees in the left-right direction from the opposite center generally within the stereoscopic field range. is doing. For this reason, it is possible to easily recognize a region where the display panel 300 is bent so that a realistic sensation can be appropriately obtained.

  Further, the display panel 300 is bent in a state in which the radius of curvature is continuously reduced along both side edges in the left-right direction. For this reason, it is possible to easily obtain a feeling of being wrapped in an image, and to improve the sense of reality more easily.

  The display panel 300 is formed so as to be highly flexible, i.e., to be easily bent, at least along both edge sides. For this reason, the structure bent to the state where a curvature radius becomes small continuously according to both ends is easily obtained.

  In addition, the display panel 300 is used which is highly flexible along both left and right end edges, that is, is easily bent along both end edges. For this reason, it can be easily bent with a simple configuration in such a manner that the radius of curvature continuously decreases in accordance with both end edges.

  Furthermore, both end edges of the display panel 300 formed so as to be easily bent along both left and right end edges are urged toward the reference point G. Therefore, for example, as described above, the link mechanism 532B can be operated by driving the drive unit 532A to urge both end edges, and a realistic feeling can be easily obtained with a simple configuration, and the device can be made compact. And improvement of manufacturability can be easily achieved.

  Further, as a process of urging both left and right edges of the display panel 300 to the reference point G side, a control for urging the display panel 300 in accordance with the length of the separation distance, that is, in a distance relationship inversely proportional to the length of the separation distance. is doing. For this reason, the control for bending the curvature radius to be continuously reduced along both edge sides can be easily obtained by the simple control of the drive unit 532A for operating the link mechanism unit 532B in the bending means 532 having a simple configuration. Simplification of configuration and speeding up of processing can be easily obtained.

  Then, by using a liquid crystal display panel, an EL panel, an electrophoretic display panel, or the like as the display panel 300, a thin configuration with a bendable configuration can be obtained, so that a configuration with a simple configuration can be easily obtained. be able to. Further, the display device 600 can be easily downsized.

  In particular, the region outside the stereoscopic field range is bent in a wide left-right direction. For this reason, compared with the structure which bends the circumference | surroundings, the structure which can obtain a realistic feeling easily with a simple structure can be obtained.

[Modification of Embodiment]
In addition, this invention is not limited to each embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

  In other words, the playback system 100 in which the display device 600 and the audio device 700 are built in the chair 200 has been described as an example. However, a display adjustment device that only has the display device 600 or bends the display panel 300, such as a television. Any usage form is applicable, such as a configuration in which 530 is mounted on the display panel 300 as an independent configuration.

  In the above description, the display panel 300 is bent in the left-right direction, but the periphery of the display panel 300 may be bent in a concave shape. With this configuration, the sensation of being wrapped in video is improved, and the sense of reality can be further improved.

  Further, the configuration of the bending means 532 to be bent is not limited to the configuration including the above-described link mechanism portion 532B, and may be configured to be urged as shown in FIG. Specifically, as shown in FIG. 5, the drive unit 532 </ b> A is disposed substantially opposite to the reinforcing member 532 </ b> B <b> 3 provided on the periphery of the display panel 300. Further, the moving part 532B1 is disposed so as to be able to advance and retreat along a direction facing the reinforcing member whose longitudinal direction is the front-rear direction, and is connected to the reinforcing member 532B3 to constitute the bending means 550. And when bending the display panel 300, it is good also as a structure which advances the moving part 532B1 and urges | biases directly.

  Furthermore, the bending configuration is not limited to the configuration shown in the embodiment shown in FIGS. 1 to 4 or the embodiment shown in FIG. 5 described above. For example, the approximate center of the display surface is set to the reference point G. It is good also as a structure which is moved and bent in the state which moves away. Specifically, for example, as shown in FIG. 6, an opening surface having substantially the same shape as the outer shape of the display panel 300 is opened on one surface side, and a guide portion 561 in a state of expanding toward the opening surface is provided with a support portion 260. Secure to. A duct 562 communicating with an intake device as a moving means such as a compressor is provided in a suction hole provided substantially at the center of the guide portion 561 to constitute a bending means 560. In addition, the guide part 561 is formed in a state in which the inner peripheral surface is in substantially airtight contact with the peripheral edge of the display panel and the entire peripheral edge of the display panel 300 slides equally. When the display panel 300 is bent, the suction device is driven to suck the air in the guide portion 561 that is substantially airtightly closed by the display panel 300. As a result, the air pressure in the guide portion 561 becomes smaller than the atmospheric pressure, the display surface side of the display panel 300 is pushed to the atmospheric pressure, and the bending radius is bent along the periphery. With this configuration, it is possible to obtain a simple configuration that bends not only the left-right direction but also the substantially entire periphery. The amount to be bent may be determined by detecting the amount of air to be sucked in or the atmospheric pressure in the guide portion 561 and controlling the bending state based on the detection results. In addition, it may be bent by any method.

  In the above description, the curvature radius is bent continuously in accordance with both end edges. However, only the region outside the stereoscopic field range may be bent. In this case, as the display panel 300, for example, as shown in the embodiment shown in FIG. 5 and the embodiment shown in FIG. A reinforcing member may be provided. The bending state can be easily set by setting the partial flexibility in the display panel 300 as described above.

  Furthermore, although the display panel 300 is bent and controlled so that the viewing distances within and outside the stereoscopic field range are different, the present invention is not limited to this configuration. For example, as shown in FIG. 7, a Fresnel lens 800 having a size corresponding to the outer diameter of the display surface of the display panel 310 is supported on the support portion 260 on the front surface of the display panel 310 in a substantially parallel manner. A configuration may be adopted in which at least both ends in the left-right direction of the Fresnel lens 800 are bent to the reference point G side by a bending means 550 similar to the form. In addition, the bending means 550 is disposed so as not to interfere with the display panel 310 as a configuration in which the both ends in the vertical direction of the Fresnel lens 800 are urged. In the configuration shown in FIG. 7, both ends in the left-right direction of the Fresnel lens 800 are bent based on the distance between the Fresnel lens 800 and the reference point G. As a result, both ends of the Fresnel lens 800 are separated from the display surface, and the magnification in that region is increased in accordance with both ends. For this reason, the viewing distance of the image area visually recognized by the Fresnel lens 800 outside the stereoscopic field of view becomes a state close to both bent portions, and the operational effect of improving the sense of reality as in the above-described embodiments. Is obtained. In addition, since the Fresnel lens 800 is used, an enlarged image can be visually recognized, so that the display panel 310 having a relatively small display surface can be used. Furthermore, non-flexible display means such as PDP (Plasma Display Panel) and CRT (Cathode-Ray Tube) can be used, and versatility can be improved. Note that the embodiment shown in FIG. 7 is not limited to the configuration in which the Fresnel lens 800 is bent similarly to the embodiment shown in FIGS. 1 to 4 described above, and for example, the entire periphery is bent or the bending means 550 is bent. It may be bent with a configuration other than the above. Further, although the separation distance between the Fresnel lens 800 and the reference point G is measured, the separation distance between the display surface and the reference point G may be measured.

  Furthermore, in addition to using the Fresnel lens 800, for example, using a lens whose magnification can be changed or using a configuration in which the magnification can be changed by a plurality of lenses, the viewing distance inside and outside the stereoscopic field range is different. The configuration is available.

  Further, as a display surface of the display means, for example, a screen on which an image is projected by a projector may be used as a display surface, and the screen may be bent.

  In addition, the specific structure and procedure for carrying out the present invention can be changed as appropriate to other structures and the like within the scope of achieving the object of the present invention.

[Effect of the embodiment]
As described above, the image of the region visually recognized outside the stereoscopic field range at the reference point G is controlled to be a viewing distance closer to the visual distance in the region image recognized within the stereoscopic field range. For this reason, since the image of the area that is visually recognized outside the stereoscopic field of view is felt by the user X, the screen is displayed like a substantially drum shape in which the width dimension in the vertical direction at both ends in the horizontal direction is wide. This makes it possible to improve the sense of presence by providing a sense of being wrapped in the image.

  Further, based on the distance between the reference point G and the display surface of the display panel 310 and the size of the display surface, the reference point G is set with the opposing direction in the Fresnel lens disposed between the display surface and the reference point G as the central axis. A region corresponding to a region that is visually recognized as a center in the left-right direction and a region outside the range of 60 degrees in the center angle is recognized, and the region is bent toward the reference point G to be smaller than another radius of curvature. For this reason, the magnification in the region outside the stereoscopic field range outside the range of 60 degrees is increased, and the image of the region visually recognized outside the stereoscopic field range by the user X is felt nearby, and the feeling of being wrapped in the image is felt. It can be obtained and the presence can be improved.

  Then, the region of the display surface of the display panel 300 that can be bent and deformed located outside the stereoscopic field range at the reference point G is bent toward the reference point G in a state smaller than another radius of curvature. For this reason, an image in a region outside the stereoscopic field range outside the range of 60 degrees can be felt closer to the user X, so that a sense of being wrapped in the image can be obtained and the sense of reality can be improved.

  Further, based on the separation distance between the reference point G and the display surface of the display panel 310 and the size of the display surface, the central angle in the left-right direction with the reference point G as the center axis and the reference point G as the center axis, respectively. The area of the display surface that can be bent and deformed on the display panel 300 located outside the range of 60 degrees is bent toward the reference point G in a state smaller than the other curvature radius. For this reason, an image in a region outside the stereoscopic field range outside the range of 60 degrees can be felt closer to the user X, so that a sense of being wrapped in the image can be obtained and the sense of reality can be improved.
