It is possible to provide a novel information processing device that can display on a large, seamless screen. In this specification, an image includes information that can be perceived visually, such as characters and symbols. do.

[0052] The arithmetic device 110 described as an example in this embodiment includes an input / output interface 11 5 and a transmission path 114.

[0053] The input / output interface 115 can provide information to the input / output device 120. The information is provided by the force device 120 .

[0062] <Bending position sensor> The folding position sensor 123 detects the position at which the display unit 122 is folded. For example, if the bending position is predetermined, If there are multiple bending positions, multiple sensors are placed at that position. By arranging them in a line or matrix, the coordinates of the folded position can be identified. It is possible.

[0063] The folding position sensor 123 can be provided, for example, along the outer periphery of the display unit 122 . In the case of the information processing device 100 illustrated in FIG. 1B-1, the folding position sensor 123 displays The ribs 122 are provided along the longitudinal direction of the portion 122. good.

[0064] The folding position sensor 123 provided to surround the display unit 122 It is possible to detect the bending position in various directions across the board, for example, horizontally, vertically or diagonally. This allows the display unit 122 to be divided at various positions.

[0065] The bending position sensor 123 may be, for example, a switch, a MEMS pressure sensor, or a pressure sensor. It can be constructed using:

[0066] Specifically, a switch having a mechanical contact, a magnetic switch, or the like is used by folding the display unit 122. The display unit 122 may be arranged so as to open and close in response to bending and unfolding movements.

[0067] Alternatively, a plurality of pressure sensors may be provided on the display unit 122. A piezoelectric element in the shape of a cylinder can be attached to the display unit 122. The bending position can be determined by detecting the increase in pressure that accompanies the bending operation. .

[0068] As the piezoelectric element, for example, an organic piezoelectric film can be used. Acid-containing piezoelectric film, polyvinylidene fluoride-containing piezoelectric film, polyester or a piezoelectric film containing a chiral polymer, etc. can be used.

[0069] The piezoelectric element may be used in combination with the bending position sensor 123 and a pressure-sensing touch panel. stomach.

[0071] For example, the user of the information processing device 100 may input a display end command or an image end command from the input means 121. It is possible to input an operation command including a command to select an area. Or, a page turning command or the like can be input.

[0072] The bending position information SENS may also be inputted in a pseudo manner using the input means 121. As a result, one display unit is divided into two with the position information input using the input means 121 as the boundary. As a result, for example, different images can be displayed in each area. .

[0082] For example, in games, accurately predicting the movement of a character moving between two areas It is possible.

[0083] <Variation 1> An information processing device exemplified in Modification 1 of this embodiment will be described with reference to FIG. .

[0084] FIG. 3 shows a modified example of the program executed by the calculation unit 111 of the information processing device according to one embodiment of the present invention. FIG.

[0085] The information processing device exemplified in the first modification of this embodiment is a program executed by the calculation unit 111. The interrupt processing of this system is different from that of the information processing device described with reference to FIG. Here, the different parts will be described in detail, and the parts that can use the same configuration will be described in the above. The explanation is cited.

[0086] A first modification of this embodiment has the following interrupt processing instead of the above interrupt processing: In the sixth step, the display end command and the folding position information SENS are received. (See Figure 3(U6)).

[0087] In the seventh step, if the bending position information SENS was not provided in the sixth step, If the bending position information SENS is provided, proceed to the 8th step. Proceed to step (see Figure 3 (U7)).

[0088] In the eighth step, an image is selected from the plurality of images. For example, in the first step, A plurality of pieces of image information are read in and displayed in tiles on the display unit 122 as initial images. Then, the user may select one of the images using the input means 121 (see FIG. 3(U)). See 8).

[0089] In the ninth step, the part to be displayed on the display unit is selected from the one image selected in the eighth step. Generate an undivided image (see Figure 3 (U9)).

[0090] In the tenth step, two images are selected from the plurality of images. For example, in the first step, A plurality of image information read by the app is displayed in tiles, and the user can input the image information by using the input means 121. Two images may be selected (see Figure 3 (U10)).

[0091] In the eleventh step, the first region 122(a) and the second region 122(b) are separated by the folded position. The image divided into regions 122(b) is generated from the two images selected in the tenth step. (See Figure 3 (U11)).

[0092] In the twelfth step, the process returns from the interrupt process (see (U12) in FIG. 3).

[0093] The information processing device described in the modified example of this embodiment has one display area at a folded position. The image to be displayed on the display unit 122 can be selected by dividing it into two.

[0094] <Variation 2> An information processing device exemplified in Modification 2 of this embodiment will be described with reference to FIG. 6. .

[0095] FIG. 6 shows a modified example of the program executed by the calculation unit 111 of the information processing device according to one embodiment of the present invention. Illustrative flow diagrams and schematic diagrams.

[0096] The information processing device exemplified in the second modification of this embodiment is a program executed by the calculation unit 111. The interrupt processing of this system is different from that of the information processing device described with reference to FIG. Here, the different parts will be described in detail, and the parts that can use the same configuration will be described in the above. The explanation is cited.

[0097] The second modification of this embodiment has the following interrupt processing instead of the above interrupt processing: In the sixth step, the display end command and the folding position information SENS are received. (See Figure 6(A)(V6)).

[0098] In the seventh step, if the bending position information SENS was not provided in the sixth step, If the bending position information SENS is supplied, proceed to step 8. Proceed to step (see Figure 6(A)(V7)).

[0099] In the eighth step, if the display unit 122 is not folded in a mountain fold, proceed to the eleventh step. If the folding is mountain-folded, proceed to the ninth step (see FIG. 6(A)(V8)).

[0100] Whether the display unit 122 is folded in a mountain fold or a valley fold can be determined by, for example, an acceleration sensor. This can be determined using a shear force sensor or a shear force sensor.

[0101] Specifically, the acceleration sensors 100S provided at the four corners of the display unit 122 are used to measure the speed of the display unit 122. The acceleration applied to the four corners of the display unit 122 when the display unit 122 is bent is detected, and the trajectory drawn by the four corners of the display unit is calculated. (See FIG. 6(B-1)). This allows us to determine whether the display section is mountain-folded or valley-folded. It is possible to know whether the paper has been folded (see Figure 6(B-2)).

[0102] In addition, a shear force sensor provided on the display unit 122 is used to detect the shear force of the display unit 122 when the display unit 122 is folded in a mountain fold. You can see whether the paper has been folded or not.

[0103] In the ninth step, the folding position F closest to the center C of the display unit 122 is identified ( See Figure 6(A)(V9)).

[0243] FIG. 9 is a cross-sectional view illustrating the configuration of touch panel 400B.

[0245] <Display section> The display unit 401 includes a plurality of pixels arranged in a matrix. It includes a pixel circuit that drives the element.

[0246] 《Pixel configuration》 The pixel includes a sub-pixel 402R, which comprises a light-emitting module 480R.

[0248] The light emitting module 480R includes a first light emitting element 450R and an optical element (e.g., a first color layer 467R).

[0249] The first light emitting element 450R includes a lower electrode, an upper electrode, and a light emitting active layer between the lower electrode and the upper electrode. The layer includes an organic compound.

[0250] The light emitting module 480R has a first colored layer 467R in the direction in which light is extracted. The light emitting element may transmit light having a specific wavelength, such as red, green, or blue.
