[0005] Patent Document 1: Japanese Patent Application Publication No. 2013-231745 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] In the display device described in Patent Document 1, multiple colored pixels of various colors are arranged along the arrangement direction of the multiple viewpoints, with a width greater than the width in the arrangement direction of the multiple viewpoints in a direction orthogonal to the arrangement direction of the multiple viewpoints. In such a structure, sometimes the color of light reaching each viewpoint from the colored pixels becomes different. In this case, undesirable coloring is produced in the image visually recognized at each viewpoint.

[0036] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Furthermore, the disclosure is merely an example, and appropriate modifications that maintain the spirit of the invention and are readily conceived by those skilled in the art are naturally included within the scope of this disclosure. Additionally, to make the description clearer, the drawings may sometimes schematically represent the width, thickness, shape, etc., of various parts compared to the actual form; however, this is merely an example and does not limit the interpretation of the present disclosure. Furthermore, in this specification and the various drawings, the same reference numerals are used for elements that are the same as those described in the previously presented drawings, and detailed descriptions are sometimes appropriately omitted.

[0037] Figure 1 as well as Figure 2This is a schematic diagram illustrating the basic idea of ​​a method for outputting individual images to multiple viewpoints via the display device of this disclosure. In the following description, the arrangement direction of the multiple viewpoints E(n), E(n+1), the length direction of the pixel Spix (e.g., the first pixel Rpix, the second pixel Gpix, and the third pixel Bpix), i.e., the arrangement direction of the multiple pixel Spixes, or the extension direction of the scan lines described later, is defined as the first direction Dx. Furthermore, the direction orthogonal to the first direction Dx and along the display output surface of the image is defined as the second direction Dy. Additionally, the direction orthogonal to both the first direction Dx and the second direction Dy is defined as the third direction Dz.

[0038] The display device of the present invention includes a pixel Spix, whose width in a first direction Dx is larger than its width in a second direction Dy, and a light-shielding portion SM. Figure 1 Within the accompanying drawings based on this disclosure, as examples of pixels (Spix), a first pixel Rpix, a second pixel Gpix, and a third pixel Bpix are illustrated. In the first pixel Rpix, the peak of the output light spectrum is visually perceived as red. In other words, from the user's perspective, the first pixel Rpix is ​​a red pixel (Spix). In the second pixel Gpix, the peak of the output light spectrum is visually perceived as green. In other words, from the user's perspective, the second pixel Gpix is ​​a green pixel (Spix). In the third pixel Bpix, the peak of the output light spectrum is visually perceived as blue. In other words, from the user's perspective, the third pixel Bpix is ​​a blue pixel (Spix). The pixel (Spix) is not limited to this; it can also be a spectrum of colors other than red, green, and blue, where the peak of the output light spectrum is visually perceived as red. For example, from the user's perspective, a white pixel (Spix) can also be further provided. Furthermore, these adjacent first pixels Rpix, second pixels Gpix, and third pixels Bpix form a unit pixel in the display area AA (refer to...). Figure 5 In this context, the unit pixels are arranged in a matrix.

[0039] The pixel Spix is ​​arranged in two dimensions along a plane orthogonal to the third direction Dz. Figure 1 The example illustrates pixel columns A(n) and A(n+1) arranged from one side of the second direction Dy towards the other in the order of first pixel Rpix, second pixel Gpix, and third pixel Bpix. Pixel columns A(n) and A(n+1) are arranged in the first direction Dx. In the example of this disclosure, pixels of the same color are arranged in the first direction Dx, but this is not a limitation; pixels of different colors can also be arranged in the first direction Dx.

[0040] The light-shielding part SM blocks a portion of the light emitted from pixel Spix in a manner that defines the ray of light emitted from pixel Spix as a defined viewpoint. Specifically, as... Figure 2 As shown, the light-blocking section SM blocks the light LL(n) from pixel column A(n) toward viewpoint E(n+1). Additionally, the light-blocking section SM blocks the light LL(n+1) from pixel column A(n+1) toward viewpoint E(n). On the other hand, the light L(n) from pixel column A(n) toward viewpoint E(n) and the light L(n+1) from pixel column A(n+1) toward viewpoint E(n+1) pass through the slit SL between the two light-blocking sections SM. In this way, the image output from pixel column A(n) can be visually recognized at viewpoint E(n), and the image output from pixel column A(n+1) can be visually recognized at viewpoint E(n+1). Furthermore, the pixels Spix of pixel columns A(n) and A(n+1) are positioned opposite viewpoint E(n) and viewpoint E(n+1) in the third direction Dz, separated by the light-blocking sections SM. The positional relationship of pixel column A(n) and pixel column A(n+1) in the first direction Dx is the opposite of the positional relationship of viewpoint E(n) and viewpoint E(n+1) in the first direction Dx.

[0041] In addition, Figure 1 In the example shown, the slit SL, which allows light to pass between the light-blocking portions SM, is tilted relative to the first direction Dx and the second direction Dy. Conversely, the pixel spixes of pixel column A(n) and pixel column A(n+1) are arranged along the second direction Dy. Thus, by tilting the slit SL relative to the pixel spix arrangement direction, moiré fringes can be suppressed.

[0042] In addition, refer to Figure 1 as well as Figure 2 The method for outputting individual images for the two most basic viewpoints (viewpoints E(n), E(n+1)) has been described. However, according to the display device of this disclosure, it is also possible to output individual images for three or more viewpoints. Hereinafter, refer to... Figures 3 to 14 The structure and control examples of a display device for outputting individual images for three or more viewpoints will be described.

[0043] Figure 3 This is a schematic diagram illustrating a structural example of a display system capable of outputting a single image for a viewpoint r. The display system includes a display device 1 and a light source device 2. The display device 1 includes a display panel 10 and a dimming panel 20. When viewed from a third party to Dz, the display panel 10 and the dimming panel 20 overlap.

[0044] The display panel 10 is a transmissive liquid crystal display panel. The display panel 10 has a display area AA (see reference) with multiple pixel spixes such as the first pixel Rpix, the second pixel Gpix, and the third pixel Bpix. Figure 5 The dimming panel 20 functions as the aforementioned light-shielding part SM. The specific structure of the dimming panel 20 will be described later.

[0045] The light source device 2 is positioned on the opposite side of viewpoints E(1), E(2), E(3), ..., E(r) across the display device 1. The light source device 2 has a light source that emits light toward the display device 1. The display device 1 allows light from the light source device 2 to pass through, outputting light L(1), L(2), L(3), ..., L(r) toward viewpoints E(1), E(2), E(3), ..., E(r). r is a natural number. Furthermore, viewpoints E(1), E(2), E(3), ..., E(r) can be viewpoints of different users, or multiple viewpoints arising from changes in the relative position between the display device 1 and the user, such as movement of the user relative to the display device 1.

[0046] Figure 4 This is a block diagram illustrating the structure related to the signal input system for the display panel 10. The display panel 10 is connected to the signal processing unit 30. The signal processing unit 30 generates an output image OP based on the input image IP input from an external device (host). The signal processing unit 30 outputs the output image OP toward the display panel 10. Each pixel of the display panel 10 performs an output corresponding to the output image OP.

[0047] Figure 5 This is a schematic diagram illustrating an example of the relationship between the arrangement of pixels (first pixel Rpix, second pixel Gpix, third pixel Bpix) in the display area AA and the viewpoint E, which is the object of the individual images output by each pixel. Figures 5 to 14 And the following Figure 21 In this context, individual images output by each pixel of the Spix are distinguished by numbers and used as the viewpoint E of the object. For example, in... Figure 5 In the diagram, each pixel (Spix) is labeled with any natural number from 1 to 13. Pixels with the same Spix number output light for the same viewpoint. Pixels with different Spix numbers output light for different viewpoints (E). Therefore, in... Figure 5 The example shown illustrates the output of individual images for 13 viewpoints. In other words, in Figure 5 In the example shown, Figure 3 The value of r in the equation is 13.

[0048] Specifically, the first pixel Rpix, the second pixel Gpix, and the third pixel Bpix, marked with "1", are the pixels Spix that output a separate image for viewpoint E(1). Similarly, the first pixel Rpix, the second pixel Gpix, and the third pixel Bpix, marked with "2", are the pixels Spix that output a separate image for viewpoint E(2). Following the same logic, the first pixel Rpix, the second pixel Gpix, and the third pixel Bpix, marked with "t", are the pixels Spix that output a separate image for viewpoint E(t). Light emitted from the light source device 2 and passing through the pixels Spix that output a separate image for viewpoint E(t) reaches viewpoint E(t) as light L(t). t is a natural number less than or equal to r.

[0049] In the display device of the present invention, pixels Spix that output individual images for the same viewpoint E are arranged continuously in the second direction Dy. Figure 5 In the example shown, there are four consecutive pixels Spix labeled with the same number (any one of 1 to 13) arranged in the second direction Dy.

[0050] Furthermore, in the display device based on this disclosure, a portion of region P (refer to...) Figure 6 The number and configuration of the pixels Spix contained in the region P are constant in relation to the individual images allocated to each pixel Spix in the partial region P.

[0051] Figure 6 It is a graph representing the relationship between the number and configuration of the pixels Spix contained in a partial region P and the individual images allocated to each pixel Spix in the partial region P. Figure 6 The shown region P contains the pixel Spix, which has a resolution of Dx × Dy = 4 × 13. (Referring to...) Figure 6 In the description, to distinguish the position of pixel Spix within a certain region P, the coordinates h, (h+1), (h+2), (h+3) on the first direction Dx and the coordinates v, (v+1), (v+2), (v+3), (v+4), (v+5), (v+6), (v+7), (v+8), (v+9), (v+10), (v+11), (v+12) on the second direction Dy are used. Furthermore, when the position of pixel Spix is ​​described by a combination of the coordinates on the first direction Dx and the coordinates on the second direction Dy, it may be recorded as (Dx, Dy) = (h, v).

[0052] exist Figure 6In the shown region P, the four Spix pixels located at (Dx, Dy) = (h, v), (h, (v+1)), (h, (v+2)), (h, (v+3)) are labeled with the number "1". That is, these four Spix pixels output a separate image for viewpoint E(1). In addition, the four Spix pixels located at (Dx, Dy) = (h, (v+4)), (h, (v+5)), (h, (v+6)), (h, (v+7)) output a separate image for viewpoint E(2). In addition, the four Spix pixels located at (Dx, Dy) = (h, (v+8)), (h, (v+9)), (h, (v+10)), (h, (v+11)) output a separate image for viewpoint E(3).

[0053] Thus, in principle, the pixels Spix of the output image for a single viewpoint E(t) are also continuously arranged in the second direction Dy within a partial region P. Figure 6 In the example shown, in addition to the viewpoints E(1), E(2), and E(3) mentioned above, the pixel Spix of the individual images output for viewpoints E(5), E(6), E(8), E(9), E(11), E(12), and E(13) is also arranged continuously in the second direction Dy within a portion of the region P.

[0054] Here, Figure 6 The number of pixel Spixes arranged in the second direction Dy of the partial region P shown is 13. Furthermore, the number of consecutive pixel Spixes output for a single image at a viewpoint E(t) is 4. Therefore, the arrangement of having four consecutive pixel Spixes output for a single image at a viewpoint E(t) within this partial region P is not possible for all viewpoints E(t). Therefore, the pixel Spixes output for a single image at a subset of viewpoints E(t) (e.g., viewpoints E(4), E(7), and E(10)) are distributed dispersedly within the partial region P.

[0055] Specifically, the four-pixel Spix output at positions (Dx, Dy) = (h, (v+12)), ((h+1), v), ((h+1), (v+1)), ((h+1), (v+2)) is a separate image relative to viewpoint E(4). Additionally, the four-pixel Spix output at positions (Dx, Dy) = ((h+1), (v+11)), ((h+1), (v+12)), ((h+2), v), ((h+2), (v+1)) is a separate image for viewpoint E(7). Furthermore, the four-pixel Spix output at positions (Dx, Dy) = ((h+2), (v+10)), ((h+2), (v+11)), ((h+2), (v+12)), ((h+3), v) is a separate image for viewpoint E(10).

[0056] Here, it can be said that the range of pixel Spixes configured for the individual image output for viewpoint E(4) is divided into the range SpA4a of (Dx, Dy) = (h, (v+12)) and the range SpA4b of (Dx, Dy) = ((h+1), v), ((h+1), (v+1)), ((h+1), (v+2)). Additionally, it can be said that the range of pixel Spixes configured for the individual image output for viewpoint E(7) is divided into the range SpA7a of (Dx, Dy) = ((h+1), (v+11)), ((h+1), (v+12)) and the range SpA7b of (Dx, Dy) = ((h+2), v), ((h+2), (v+1)). In addition, it can be said that the range of the pixel Spix of the configuration output for the individual image of viewpoint E(10) is divided into the range SpA10a of (Dx, Dy) = ((h+2), (v+10)), ((h+2), (v+11)), ((h+2), (v+12)) and the range SpA10b of (Dx, Dy) = ((h+3), v).

[0057] Range SpA4a contains pixel spixes of (h, (v+12)). Range SpA4b contains pixel spixes of ((h+1), v). Range SpA7a contains pixel spixes of ((h+1), (v+12)). Range SpA7b contains pixel spixes of ((h+2), v). Range SpA10a contains pixel spixes of ((h+2), (v+12)). Range SpA10b contains pixel spixes of ((h+3), v). Thus, it can be said that the pixel spixes output for a portion of viewpoints E(t) (e.g., viewpoints E(4), E(7), and E(10)) dispersed within a partial region P are distributed into range SpA(t)a containing pixel spixes of (Dx, Dy) = (j, kma) and range SpA(t)b containing pixel spixes of (Dx, Dy) = (j+1, kma). Here, j and j+1 are the coordinates on the adjacent first direction Dx (e.g., Figure 6 (as shown by h and (h+1), etc.). Additionally, kmax is the coordinate of the end point in the second direction Dy (e.g., Figure 6 As shown in (v+12)). Additionally, kmin is the starting coordinate on the second direction Dy (e.g., Figure 6 As shown in v). Therefore, it can be said that the range SpA(t)b is located relative to the range SpA(t)a at a position that causes the coordinates on the first direction Dx to be +1 and thus turn back. The position that turns back refers to the position relative to one end (kmax side) and the other end (kmin side) on the second direction Dy.

[0058] Figure 5 The rectangular regions P1, P2, P3, P11, P12, P13, P21, P22, and P23 shown are references respectively. Figure 6 The description refers to the region P. Figure 5 The diagram contains labels (M1, M2, M3, M11, M12, M13, M21, M22, M23) representing the position of one of the four vertices in each partial region P (partial regions P1, P2, P3, P11, P12, P13, P21, P22, P23). The positions of the labels in each partial region P are... Figure 6 The location of marker M in the partial region P shown.

[0059] Regions P1 and P2 are adjacent in the first direction Dx. Regions P2 and P3 are adjacent in the first direction Dx. Regions P11 and P12 are adjacent in the first direction Dx. Regions P12 and P13 are adjacent in the first direction Dx. Regions P21 and P22 are adjacent in the first direction Dx. Regions P22 and P23 are adjacent in the first direction Dx. Regions P1 and P11 are adjacent in the second direction Dy. Regions P11 and P21 are adjacent in the second direction Dy. Regions P2 and P12 are adjacent in the second direction Dy. Regions P12 and P22 are adjacent in the second direction Dy. Regions P2 and P12 are adjacent in the second direction Dy. In this way, the individual image for each pixel Spix is ​​allocated in the display area AA by arranging it in a way that fills multiple partial areas P.

[0060] Although not illustrated, the same reference is also applied to the region on the opposite side from the regions P2, P12, P22, separated by parts P3, P13, P23. Figure 6 The same approach applies to the allocation of individual images for pixel Spix within region P. Additionally, although not labeled in the accompanying drawings, the region on the opposite side from regions P2, P12, and P22, separated by regions P1, P11, and P21, also applies the same principle. Figure 6 The same approach applies to the allocation of individual images for pixel Spix within the region P described below.

[0061] Figure 7 It means Figure 5 This diagram illustrates the positional relationships of four adjacent sub-regions P (sub-regions P1, P2, P11, and P12) within a plurality of sub-regions P. Figure 5 as well as Figure 7 As shown, in the display device of the present invention, the positions of two adjacent partial regions P in the second direction Dy are offset in the first direction Dx. For example... Figure 5 as well as Figure 7 As shown, regions P1 and P11 are adjacent in the second direction Dy. The position of region P1 in the first direction Dx is offset from the position of region P11 in the first direction Dx. Similarly, regions P2 and P12 are adjacent in the second direction Dy. The position of region P2 in the first direction Dx is offset from the position of region P12 in the first direction Dx.

[0062] Similarly, as Figure 5As shown, regions P11 and P21 are adjacent in the second direction Dy. The position of region P11 in the first direction Dx is offset from the position of region P21 in the first direction Dx. Similarly, regions P12 and P22 are adjacent in the second direction Dy. The position of region P12 in the first direction Dx is offset from the position of region P22 in the first direction Dx. Regions P3 and P13 are adjacent in the second direction Dy. The position of region P3 in the first direction Dx is offset from the position of region P13 in the first direction Dx. Figure 5 In the example shown, the position of two adjacent partial regions P in the second direction Dy is offset from the width by one pixel Spix in the first direction Dx by the width D4 (refer to...). Figure 6 ).

[0063] Because the positions of two adjacent partial regions P in the second direction Dy are offset in the first direction Dx, the range SpA(t)b of one of these two partial regions P (refer to...) Figure 6 The range SpA(t)a of the other side of the two partial regions P is continuous in the second direction Dy. Figure 5 The range StA4 shown is formed by the continuation of the ranges SpA4b and SpA4a of a portion of region P1 and P11, respectively. Similarly, range StA7 is formed by the continuation of the ranges SpA7b and SpA7a of a portion of region P1 and P11, respectively. Furthermore, range StA10 is formed by the continuation of the ranges SpA10b and SpA10a of a portion of region P1 and P11, respectively. Figure 5 The example shows the ranges StA4, StA7, and StA10 that are valid through partial regions P1 and P11, but the same state is valid through two adjacent partial regions P in the second direction Dy.

[0064] Because the positions of two adjacent partial regions P in the second direction Dy are offset in the first direction Dx, multiple partial regions P are arranged along a straight line forming an acute angle θ1 with the first direction Dx. Figure 5In the diagram, the arrangement of partial regions P1, P11, and P21, forming an acute angle θ1 with respect to line Lx along the first direction Dx, is shown by the dashed line DL1 connecting markers M1, M11, and M21. Similarly, the arrangement of partial regions P2, P12, and P22, forming an acute angle θ1 with respect to line Lx, is shown by the dashed line DL2 connecting markers M2, M12, and M22. Furthermore, the arrangement of partial regions P3, P13, and P23, forming an acute angle θ1 with respect to line Lx, is shown by the dashed line DL3 connecting markers M3, M13, and M23.

[0065] Since the positions of two adjacent partial regions P in the second direction Dy are offset in the first direction Dx, the arrangement of multiple partial regions P along a straight line forming an acute angle θ1 with the first direction Dx can also be described as the arrangement of multiple partial regions P along a straight line forming an acute angle θ2 with the second direction Dy. Figure 5 The diagram only shows the acute angle θ2 formed between line DL1 and line Ly along the second direction Dy, but other lines DL2 and DL3 also form an acute angle θ2 with the second direction Dy.

[0066] Furthermore, a portion of a partial region P is configured in the area where a partial region is not fully included due to the offset between adjacent partial regions P. That is, the pixel spix in the pixel spix contained in partial region P that is not fully included in the display area AA is omitted.

[0067] Acute angles θ1 and θ2 are based on "the deviation of adjacent regions P in the second direction Dy from each other in the first direction Dx" and "the width D4 of pixel Spix in the first direction Dx (refer to...)". Figure 6 ) and the width D3 in the second direction Dy (refer to Figure 6 The ratio of θ1 to θ2 is determined by the number of pixels (α) in the second direction Dy of the region P containing the pixels (Spix). Furthermore, the deviation of adjacent regions P in the first direction Dx from each other in the second direction Dy is represented by the number of pixels (Spix), q. Specifically, tan(θ1) = (q × D4) / (α × D3) holds. θ2 = 90° - θ1. Additionally, when q = 1, θ2 = atan{(D4 / D3) / α}. When q = 1 and D4:D3 = 3:1, θ2 = atan{3 / α}.

[0068] Furthermore, θ2 is preferably in the range of 10° to 20°, but is not limited to this; it can also be an acute angle not included in this angle range. Additionally, when the number (α) of the plurality of pixels Spix contained in the partial area P arranged in the second direction Dy is a prime number, there is a tendency to more reliably suppress moiré fringes. Furthermore, in this embodiment, a pixel refers to an area surrounded by scan lines and signal lines. More specifically, in such a display device, a plurality of scan lines are typically provided in the first direction Dx, and a plurality of signal lines are provided in the second direction Dy. Pixel electrodes and color filters are provided between these scan lines and signal lines to form a pixel. Then, in this embodiment, an area defined by the center lines of the adjacent scan lines G1 and G2 and the center lines of the adjacent signal lines S1 and S2 is defined as a pixel. Furthermore, the center line of each wiring refers to an imaginary line that passes through the center of the specified width and extends in the specified width portion (usually the portion that occupies most of the width as a wiring). Even if the width is locally increased or decreased due to each wiring, the line formed by directly extending the center line of the specified width portion before and after it is also called the center line.

[0069] In addition, in reference Figure 6 In the region P described, the number of pixels Spix arranged in the second direction Dy is 13. Additionally, in... Figure 5 In the example shown, the pixels Spix are arranged from one side of the second direction Dy towards the other in the order of first pixel Rpix, second pixel Gpix, and third pixel Bpix. Additionally, in Figure 5 In the example shown, the pixels Spx arranged along the first direction Dx are of the same type. Therefore, in regions P1, P11, and P21, the pixel Spx with coordinate v along the second direction Dy is the first pixel Rpix. Furthermore, in regions P2, P12, and P22, the pixel Spx with coordinate v along the second direction Dy is the second pixel Gpix. Additionally, in regions P3, P13, and P23, the pixel Spx with coordinate v along the second direction Dy is the third pixel Bpix. Regions P (not shown) are arranged in the same manner along the second direction Dy in the order of pixel Spx with coordinate v along the second direction Dy being the first pixel Rpix, pixel Spx with coordinate v along the second direction Dy being the second pixel Gpix, and pixel Spx with coordinate v along the second direction Dy being the third pixel Bpix.

[0070] Figure 8 This is a diagram illustrating an example of a plurality of light-shielding portions 21 disposed on the dimming panel 20 and a slit 21a formed between the plurality of light-shielding portions 21. Figure 3The dimming panel 20 shown has multiple light-shielding portions 21. For example... Figure 8 As shown, a plurality of light-shielding portions 21 are arranged in the first direction Dx. The light-shielding portions 21 serve as a reference. Figure 1 as well as Figure 2 The SM section of the light-shielding unit has the same function as described.

[0071] A slit 21a is formed between two light-shielding portions 21 arranged adjacently along the first direction Dx. The edges of the light-shielding portions 21 facing each other across the slit 21a form an acute angle θ1 with the first direction Dx. Therefore, the slit 21a is inclined at an acute angle θ1 with respect to the first direction Dx. In other words, the slit 21a is inclined at an acute angle θ2 with respect to the second direction Dy. In view of this, the dimming panel 20 can be referred to as a "light-shielding barrier", "light-shielding barrier panel", or "barrier panel".

[0072] The width D1 of the slit 21a in the first direction Dx is determined such that, as described later... Figure 22 as well as Figure 23 The "proportion of light L(t) passing through slit 21a" described herein should be as large as possible. Specifically, the width D1 is, for example, less than the width D4 in the first direction Dx of one pixel Spix (see reference). Figure 6 The width D2 of the light-shielding portion 21 between two adjacent slits 21a in the first direction Dx corresponds to the width of a partial region P in the first direction Dx. The width of a partial region P in the first direction Dx corresponds to the number of pixels Spix contained in the partial region P arranged in the first direction Dx and the width D4 of each pixel Spix in the first direction Dx.

[0073] The reference was applied. Figures 5 to 7 The display panel 10 of the display area AA of the output pixel Spix is ​​described and has a reference. Figure 8 The display device 1 formed by overlapping the light-shielding part 21 and the dimming panel 20, which are arranged in the manner of the slit 21a described above (see reference). Figure 3 It receives light from the light source device 2 and outputs an image. Thus, it is possible to... Figure 3 The viewpoints E(1), E(2), E(3), ..., E(r) shown each visually identify the individual image corresponding to their respective viewpoints.

[0074] Figure 9 This is a schematic diagram showing the output of display device 1 as observed from viewpoint E(1). Figure 10 This is a schematic diagram showing the output of display device 1 as observed from viewpoint E(2). Figure 11 This is a schematic diagram showing the output of display device 1 as observed from viewpoint E(3). For example... Figure 9 , Figure 10as well as Figure 11 As shown, when observing the output of the display device 1 from viewpoint E(t), the positional relationship between the light-shielding part 21 and the slit 21a and the pixel Spix of the display area AA is such that all the pixel Spixes that output a single image for viewpoint E(t) overlap with the slit 21a. In other words, when observing from each of the predetermined viewpoints E(1), E(2), E(3), ..., E(r) for the display device 1, the output of each pixel Spix of the display area AA and the positions of the light-shielding part 21 and the slit 21a are determined such that all the pixel Spixes that output a single image corresponding to each viewpoint overlap with the slit 21a.

[0075] In addition, such as Figure 9 , Figure 10 as well as Figure 11 As illustrated in the example, when observing the output of display device 1 from viewpoint E(t), not only the pixel Spix outputting a single image for viewpoint E(t), but also the pixel Spix outputting a single image within the range from viewpoint E(t-β) to viewpoint E(t+β) overlaps with slit 21a. B is determined based on the width D1 of slit 21a, the value of r, and other conditions. Figure 9 , Figure 10 as well as Figure 11 In the example provided, β is 2.

[0076] Furthermore, following the approach of considering the range from viewpoint E(t-β) to viewpoint E(t+β), when t-β is 0, its value is replaced by r. Additionally, when t-β is negative, its value is replaced by r+(t-β). For a specific example, when t = 1 and β = 2, t-β = -1. Therefore, when t-β is negative, its value is replaced by r+(t-β), so when r = 13, t-β is 13 + (-1) = 12.

[0077] exist Figure 9 In the example shown, the output of display device 1 is observed from viewpoint E(t), where t = 1. Additionally, β = 2. Therefore, the display area AA overlaps with slit 21a in such a way that the pixel Spix of the output for a single image of viewpoint E(1) occupies the maximum area within slit 21a. Furthermore, the pixel Spix of the output for a single image of viewpoint E(t-β) to viewpoint E(t+β), i.e., viewpoints E(12), E(13), E(1), E(2), and E(3), is located within slit 21a. With the same configuration, in Figure 10In the example shown, t = 2, so the display area AA overlaps with slit 21a in such a way that the pixel Spix of the output for a single image of viewpoint E(2) occupies the maximum range within slit 21a. Additionally, the pixel Spix of the output for a single image of viewpoints from viewpoint E(t-β) to viewpoint E(t+β), i.e., viewpoints E(13), E(1), E(2), E(3), and E(4), is located within slit 21a.

[0078] Furthermore, when observing the output of the display device 1 from viewpoint E(t), within the slit 21a, the display area AA overlaps with the slit 21a in such a way that the pixel spix that outputs a separate image for viewpoint E(t) occupies the maximum area within the slit 21a. Additionally, among the pixel spixes that output a separate image for viewpoints other than E(t), the viewpoint-facing pixel spix positioned closer to the pixel spix that outputs a separate image for viewpoint E(t) occupies a larger area within the slit 21a.

[0079] Given that t-β≥1 and t+β≤r holds, then "t-β, t-(β-1), ..., t, ..., t+(β-1), t+β" are within the range of t-β to t+β. Figure 11 In the example shown, since t = 3, the display area AA overlaps with slit 21a in such a way that the pixel Spix of the output for a single image of viewpoint E(3) occupies the maximum range within slit 21a. Additionally, the pixel Spix of the output for a single image of viewpoints E(t-β) to E(t+β), i.e., viewpoints E(1), E(2), E(3), E(4), and E(5), is located within slit 21a.

[0080] Furthermore, when t+β is a negative value exceeding r, the value of t+β is replaced with t+β-r. Although not illustrated, for example, in the case of t=13, the display area AA overlaps with slit 21a in such a way that the pixel Spix of the output for a single image of viewpoint E(13) occupies the maximum range within slit 21a. Additionally, the pixel Spix of the output for a single image of viewpoints E(t-β) to E(t+β), i.e., viewpoints E(11), E(12), E(13), E(1), and E(2), is located within slit 21a.

[0081] The above was conducted with reference to Figure 6The description is based on the premise of the partial region P, but the number and configuration of the pixel Spix contained in the partial region containing the pixel Spix of the individual images for each viewpoint E(1), E(2), E(3), ..., E(r) are not limited to the specific pattern of the partial region P.

[0082] Figure 12 It is a representation and a reference Figure 6 The diagram illustrates examples of different regions P31 and P32 within region P. Figure 12 The shown regions P31 and P32 contain 36 × 4 = 144 pixels (Spix). Therefore, in... Figure 12 In the example shown, r = 36.

[0083] Furthermore, regarding the following cases: the number of pixels Spix contained in partial regions P31 and P32 arranged in the second direction Dy is 13; there are four consecutive pixels Spix that output a single image for a viewpoint E(t) in the second direction Dy; the configuration of pixels Spix that output a single image for a viewpoint E(t) is folded back when there are not four consecutive pixels Spix that output a single image for a viewpoint E(t) in the second direction Dy; and the amount (width D4) by which adjacent partial regions P31 and P32 in the second direction Dy are offset from a pixel Spix in the first direction Dx, partial regions P31 and P32 are the same as the aforementioned partial region P.

[0084] exist Figure 12 In the regions P31 and P32 shown, a single pixel Spix of the output image for viewpoint E(36) protrudes towards one end in the first direction Dx. Therefore, in Figure 12 In the example shown, the positions of adjacent regions in the first direction Dx are offset from each other by one pixel Spix (width D3) in the second direction Dy. Furthermore, it is not limited to... Figure 12 The regions P31 and P32 shown are configured such that a portion of the pixel Spix protrudes to one end in the first direction Dx and becomes a non-rectangular shape. Similarly, in the second direction Dy, the positions of adjacent regions in the first direction Dx are offset from each other.

[0085] As mentioned above, the number of pixels Spix arranged in the second direction Dy within regions P31 and P32 is 13, which is the same as in region P. Therefore, Figure 12The inclination relative to the first direction Dx resulting from the arrangement of partial regions P31 and P32 along the second direction Dy is the same as the inclination relative to the first direction Dx resulting from the arrangement of the aforementioned partial regions P1, P11, P21, ... along the second direction Dy. Specifically, lines DL4 and DL5, passing through the common vertices of partial regions P31 and P32, form an acute angle θ1 with line Lx. Furthermore, lines DL4 and DL5 naturally form an acute angle θ2 with line Ly.

[0086] The width D5 of each region P31 and P32 in the first direction Dx corresponds to the number of pixels Spix contained in each region P31 and P32 in the first direction Dx (12) and the width D4 of each pixel Spix in the first direction Dx. When using... Figure 12 In the case of the partial regions P31 and P32 shown, refer to Figure 8 The width of the light-shielding portion 21 located between the two slits 21a in the first direction Dx is described as the width corresponding to the width D5.

[0087] Next, refer to Figure 13 as well as Figure 14 For reference Figure 5 The construction of the output of the display area AA is explained.

[0088] Figure 13 This is a schematic diagram illustrating the relationship between the subject SUB and the imaging devices C(1), C(2), ... C(r). For example... Figure 13 As shown, the image data used to enable the output of the display area AA is generated by capturing images of the subject SUB using multiple capturing devices C(1), C(2), ... C(r). The capturing devices C(1), C(2), ... C(r) capture images of the subject SUB from different angles. Preferably, the capturing devices C(1), C(2), ... C(r) are arranged sequentially along an arc centered on point AoR within the subject SUB.

[0089] Furthermore, the image data used to establish the output of the display area AA can also be generated using fewer than r number of imaging devices. For example, one imaging device C(1) takes a picture of the subject SUB once. Then, the subject SUB is rotated by a predetermined angle in the rotation direction VR with point AoR as the center, and then the imaging device C(1) takes another picture of the subject SUB, repeating this process (r-1) times. The predetermined angle corresponds to the angle difference between the imaging devices C(1) and C(2) relative to point AoR. Thus, the same imaging result as that generated by using multiple imaging devices C(1), C(2), ... C(r) to take pictures of the subject SUB can be obtained. In addition, instead of rotating the subject SUB, by deviating the shooting angle of the imaging device C(1) relative to the subject SUB from the predetermined angle, the same imaging result as that generated by using multiple imaging devices C(1), C(2), ... C(r) to take pictures of the subject SUB can also be obtained.

[0090] Figure 14 It indicates a reference. Figure 13 This diagram illustrates the relationship between the input image IP and the output image OP. The input image IP comprises a number of input images IP(1), ..., IP(r) corresponding to the number of viewpoints E(r). Figure 14 The example shown is for r=13. The output image OP is image data that can be output to the display area AA of a display panel 10. (Refer to...) Figure 14 In the explanation, prioritizing ease of understanding, it is assumed that the resolution of the input images IP(1), ..., IP(r), as well as the color and configuration of the pixel Spix, are the same as the resolution of the output image OP, as well as the color and configuration of the pixel Spix. Specifically, in Figure 14 In, to include and refer to Figure 6 The example shown is the pixel region of Spix, which corresponds to a Dx×Dy=4×13 pixel region P.

[0091] Reference Figure 4 The signal processing unit 30 described herein extracts a portion from each of the input images IP(1), ..., IP(r), which correspond to the number of viewpoints E (r). The signal processing unit 30 generates an output image OP by combining the portions extracted from each of the input images IP(1), ..., IP(r). Furthermore, it pre-determines which pixel Spix in the output image OP is assigned to the pixel Spix contained in each portion of the input images IP(1), ..., IP(r). (Refer to...) Figure 14 In the description, it is assumed that the annotation is based on the reference. Figure 6 The numbering of the viewpoint E(t) of the partial region P (any one of 1 to 13) indicates a predetermined assignment.

[0092] In the process of generating the output image OP based on the input image IP, firstly, the signal processing unit 30 performs a setting process, in which t is set with an initial value (1). Next, the signal processing unit 30 performs a determination process, in which the coordinates of the pixel Spix assigned to the viewpoint E(t) in the output image OP are determined. Then, the signal processing unit 30 performs an acquisition process, in which a grayscale value is acquired in the input image IP(t) corresponding to the input image (t) that has the same coordinates as those determined in the determination process. Finally, the signal processing unit 30 performs an application process, in which the grayscale value acquired in the acquisition process is applied to the output image OP. In the application step, the grayscale value is applied in such a way that the coordinates of the pixel Spix of the input image IP, which serves as the source of the grayscale value, are consistent with the coordinates of the pixel Spix of the output image OP to which the grayscale value is applied.

[0093] For example, in Figure 14 In the output image OP shown, the coordinates of the pixel Spix assigned for viewpoint E(1) are (Dx, Dy) = (h, v), (h, (v+1)), (h, (v+2)), (h, (v+3)). Therefore, the signal processing unit 30 obtains the grayscale value set for each pixel Spix in the extraction range PU(1) containing (Dx, Dy) = (h, v), (h, (v+1)), (h, (v+2)), (h, (v+3)) of the input image IP(1), and applies the obtained grayscale value to (Dx, Dy) = (h, v), (h, (v+1)), (h, (v+2)), (h, (v+3)) of the output image OP.

[0094] After the application process is completed, the signal processing unit 30 performs an addition operation by adding 1 to t. After the addition operation, the determination, acquisition, and application processes are performed again. The signal processing unit 30 repeatedly performs the addition operation until t after the addition operation becomes the same value as r. By completing the determination, acquisition, and application processes performed after the last addition operation, the generation process of the output image OP based on the input image IP is completed.

[0095] For example, in Figure 14In the output image OP shown, the coordinates of the pixel Spix assigned for viewpoint E(2) are (Dx, Dy) = (h, (v+4)), (h, (v+5)), (h, (v+6)), (h, (v+7)). Therefore, the signal processing unit 30 obtains the grayscale value set for each pixel Spix of the extraction range PU(2) containing the input image IP(2) (Dx, Dy) = (h, (v+4)), (h, (v+5)), (h, (v+6)), (h, (v+7)), and applies the obtained grayscale value to the output image OP (Dx, Dy) = (h, (v+4)), (h, (v+5)), (h, (v+6)), (h, (v+7)). Based on the same approach, the signal processing unit 30 obtains the grayscale value set for each pixel Spix of the extraction range PU(3) containing the input image IP(3) (Dx, Dy) = (h, (v+8)), (h, (v+9)), (h, (v+10)), (h, (v+11)), and applies the obtained grayscale value to the output image OP (Dx, Dy) = (h, (v+8)), (h, (v+9)), (h, (v+10)), (h, (v+11)). Subsequently, the signal processing unit 30 obtains the grayscale value set for a portion of the pixels Spix of the input image IP(t) up to the extraction range PU(13) of the input image IP(13), and applies the obtained grayscale value to the corresponding coordinates of the output image OP.

[0096] exist Figure 14 In, to include and refer to Figure 6 Taking the pixel region of the region P corresponding to the pixel region Spix of Dx×Dy=4×13 as an example, however, in reality, the resolution of the input image IP and the output image OP is mostly large. In the case of input image IP and output image OP with even larger resolutions, the signal processing unit 30 refers to... Figure 5 as well as Figure 7 The description specifies multiple partial regions (e.g., partial regions P1, P2, P3, P11, P12, P13, P21, P22, P23, ...), each with its own reference. Figure 14 The following describes the generation process of the output image OP based on the input image IP. Specifically, the signal processing unit 30 applies the same partial regions (e.g., partial regions P1, P2, P3, P11, P12, P13, P21, P22, P23, ...) applied to the display area AA to both the input image IP and the output image OP. Then, the signal processing unit 30 applies a reference to each partial region. Figure 14 This describes the process of generating an output image OP based on an input image IP.

[0097] Furthermore, the resolution, pixel spix color, and configuration of the output image OP are the same as the number (display resolution), color, and configuration of pixel spixes contained in the display area AA. On the other hand, the resolution, pixel spix color, and configuration of the input image IP are not necessarily the same as the resolution, pixel spix color, and configuration of the output image OP at the input time point for the signal processing unit 30. When the resolution, pixel spix color, and configuration of the input image IP are different from those of the output image OP, the signal processing unit 30 performs a conversion process to make the resolution, pixel spix color, and configuration of the input image IP match those of the output image OP. As specific content of image processing performed in the conversion process, for example, other image completion processes such as nearest neighbor completion and linear completion can be applied.

[0098] The signal processing unit 30 is a circuit that performs the various processes included in the generation process of the output image OP based on the input image IP, as well as the conversion process. The signal processing unit 30 can be composed of a single circuit having all of these functions, or it can be composed of a combination of multiple circuits having some of these functions. The signal processing unit 30 can be mounted on the substrate of the display panel 10, or it can be mounted on another substrate (e.g., a flexible substrate) connected to the display panel 10. Furthermore, processes other than the acquisition process performed by the signal processing unit 30 can be performed by an external device (host). The signal processing unit 30 only needs to perform at least the application process.

[0099] Next, refer to Figure 15 For reference Figure 3 A more detailed structural example of the display device 1 will be described below.

[0100] Figure 15 It means Figure 3A more detailed structural example of the display device 1 shown is illustrated. The display panel 10 includes a first substrate 11, a second substrate 12, a first polarizing layer 13, and a first polarizing layer 14. The first substrate 11 is a light-transmitting substrate on which the following components are mounted: a pixel electrode individually disposed on a pixel Spx; a switching element, either a source or a drain, connected to the pixel electrode; a signal line connected to the other of the source or drain of the switching element; a scan line that transmits a drive signal to the gate of the switching element; a source driver that outputs a pixel signal corresponding to the output image OP to each pixel Spx to the signal line; and a gate driver that outputs the drive signal to the scan line according to the output timing of the pixel signal. The second substrate 12 is a light-transmitting substrate on which a color filter, etc., is provided to transmit light of a color corresponding to the peak value of the spectrum of light output from each pixel Spx, is provided. Alternatively, a structure in which the color filter is disposed on the first substrate 11 side may also be adopted. Furthermore, a common electrode, which is shared by multiple pixel Spx and represents a constant potential, is disposed on either the first substrate 11 or the second substrate 12. Although not shown, liquid crystal is sealed between the first substrate 11 and the second substrate 12. The first polarizing layer 13 and the first polarizing layer 14 are polarizing plates or polarizing films that allow light in a predetermined deflection direction to pass through and block light in other deflection directions. The first polarizing layer 13 is disposed on the side of the light source device 2 relative to the first substrate 11. The first polarizing layer 14 is disposed on the side of the dimming panel 20 relative to the second substrate 12. By controlling the deflection direction of light based on liquid crystal molecules according to the pixel signal orientation, and by combining the deflection directions of light transmitted through the first polarizing layer 13 and the first polarizing layer 14, the brightness of the light transmitted through the display panel 10 is controlled in units of pixels (Spix).

[0101] The dimming panel 20 includes a light-shielding portion 21, a substrate 22, and an adhesive layer 23. The light-shielding portion 21 is a reference... Figures 8 to 11 The light-shielding portion 21 is described. Furthermore, the light-shielding portion 21 can be formed, for example, using black synthetic resin or chromium (Cr) processed to reduce light reflectivity based on the outer peripheral surface, but is not limited to these; other materials with light-shielding properties can also be used. The substrate 22 is a substrate that fixes the light transmittance of the light-shielding portion 21. Furthermore, the substrate 22, as well as the first substrate 11 and the second substrate 12, can be, for example, a glass substrate, but can also be a substrate with light transmittance based on other materials. The adhesive layer 23 is an adhesive layer that bonds one side of the substrate 22 where the light-shielding portion 21 is provided to one side of the display panel 10 where the first polarizing layer 14 is provided. The adhesive layer 23 preferably uses an adhesive with excellent light transmittance. The adhesive layer 23 can also be formed from a light-transmitting film with double-sided adhesion, such as OCA (Optical Clear Adhesive).

[0102] Above, refer to Figure 15 A specific structural example of display device 1 has been described, but the specific structure of the display device based on this disclosure is not limited to that described above. Figure 3 as well as Figure 15 The structure of the explanation. Refer to the following text for further details. Figures 16 to 20 Other examples of display devices based on this disclosure are described.

[0103] Figure 16 This is a schematic diagram illustrating a structural example of display device 1A. Display device 10A can also be provided as in display device 1A, replacing the combination of light source device 2 and display panel 10 in display device 1. Display device 10A is a self-emissive display panel. Specifically, display device 10A may be, for example, an OLED (Organic Light Emitting Diode) panel or a micro-LED (Light Emitting Diode) panel, but is not limited to any of these panels; it may also be a self-emissive display panel based on other methods. Unless otherwise specified, display device 1A is identical to display device 1.

[0104] Figure 17 This is a schematic diagram illustrating a structural example of display device 1B. Display device 1B is identical to display device 1 except that the positional relationship of the display panel 10 and the dimming panel 20 relative to the light source device 2 is reversed. Thus, the positional relationship of the display panel 10 and the dimming panel 20 relative to the light source device 2 can be described as follows: Figure 15 As shown in the display device 1, the display panel 10 is located on the side of the light source device 2, or it can be as follows: Figure 17 As shown in the display device 1B, the dimming panel 20 is located on the side of the light source device 2. Unless otherwise specified, the display device 1B is the same as the display device 1.

[0105] Figure 18This is a schematic diagram showing a structural example of the display device 1C. As a replacement for the dimming panel 20 of the display device 1, the display device 1C includes a dimming panel 20A. The dimming panel 20A has an adhesive layer 23 and a lens 24. The lens 24 is an optical component with a convex lens-shaped curved shape formed on one side facing the user. The lens 24, through its convex lens-shaped curved shape on one side, refracts light emitted from the light source device 2 and passing through the display panel 10 in a manner that converges at the viewpoint E(t). Thus, the lens 24 produces the same light arrival and non-arrival relationship as the pixel Spix and viewpoint E(t) generated by the light blocking (non-arrival) based on the light blocking (non-arrival) based on the light transmission (arrival) based on the slit 21a. That is, the lens 24 achieves substantially the same effect as the light blocking 21 and the slit 21a. The adhesive layer 23 of the display device 1C is the same as the adhesive layer 23 described above, except that it bonds the other side of the lens 24 to the first polarizing layer 14. Unless otherwise specified, display device 1C is the same as display device 1.

[0106] Figure 19 This is a schematic diagram illustrating a structural example of a display device 1D. (As an alternative reference...) Figure 18 The display device 1C describes the structure of its dimming panel 20A, while the display device 1D includes a dimming panel 20B. The lens 24 of the dimming panel 20B is identical to that of the dimming panel 20A, except that its user side is flat and its opposite side has a convex lens-like curved shape. The side of the lens 24 of the dimming panel 20B with the convex lens-like curved shape is bonded to the first polarizing layer 14 via an adhesive layer 23A. The adhesive layer 23A has an adhesive area formed in a way that borders the lens 24 when viewed from the front in a plane orthogonal to the third direction Dz. The adhesive layer 23A is identical to that of the dimming panel 20A, except that the inner side of this adhesive area is hollow. Except for the matters specifically described above, the display device 1D is identical to the display device 1C.

[0107] Figure 20This is a schematic diagram illustrating a structural example of display device 1E. As a replacement for the dimming panel 20 in display device 1, display device 1E includes a dimming panel 20C. The dimming panel 20C is a liquid crystal display panel configured to form a shielding area that blocks light in the same way as the light-shielding portion 21 and a transmission area that allows light to pass through in the same way as the slit 21a. The dimming panel 20C includes a first substrate 25, a second substrate 26, and a polarizing layer 27. The first substrate 25 is the same as the first substrate 11 described above. The second substrate 26 is the same as the second substrate 12 described above, except that it does not have a color filter. Although not shown, liquid crystal is sealed between the first substrate 25 and the second substrate 26. The polarizing layer 27 has the same structure as the first polarizing layers 13 and 14 described above. The polarizing layer 27 is disposed on the opposite side of the first polarizing layer 14, separated from the first substrate 25 and the second substrate 26. By controlling the deflection direction of light based on liquid crystal molecules according to the pixel signal orientation, and combining the deflection directions of light transmitted through the first polarization layer 14 and polarization layer 27, the blocking and transmission of light to be transmitted through the dimming panel 20C are controlled at the pixel units provided on the dimming panel 20C. Furthermore, it is preferable to provide a pixel Spix with a width less than a certain value in the first direction Dx of the pixel on the dimming panel 20C. Except as otherwise specifically stated, the display device 1E is the same as the display device 1.

[0108] Furthermore, in the above description, the number of pixels Spix that output a single image for a viewpoint E(t) is four consecutive in the second direction Dy. However, the number of pixels Spix that output a single image for a viewpoint E(t) that are consecutively arranged in the second direction Dy can be more than 5 or less than 3.

[0109] Figure 21 It is a representation and a reference Figure 6 as well as Figure 12 The diagram illustrates examples of different regions P41 within region P. Figure 21 The shown region P41 contains 144 Spix pixels. Additionally, in... Figure 21 In the example shown, r = 87.

[0110] exist Figure 21 In the example shown, individual images for each viewpoint E(1), ..., E(87) are output in 144 pixel Spixes. Since 144 / 87 ≈ 1.655..., the number of pixel Spixes assigned to a viewpoint E(t) is either 1 or 2. However, by referring to... Figure 13The method for obtaining the image data (input image IP) described herein, when capturing images from multiple viewpoints such as r = 87, results in an image captured by the capturing device C(t ± η) that becomes very similar to the image captured by the capturing device C(t) as the value of η decreases. Therefore, even if the number of pixels Spix assigned to a single viewpoint E(t) is as small as 1 or 2, by operating in a manner that complements the pixel Spix assigned to viewpoint E(t ± η) with the output image, it is possible to output an image for viewpoint E(t).

[0111] Furthermore, considering the accuracy of the image output, the aforementioned η is preferably 2 or less. Hereinafter, refer to... Figure 22 as well as Figure 23 An example of a visually recognized image at viewpoint E(t) will be described, generated based on the relationship between the proportion of pixels Spix allocated to viewpoint E(t) and the proportion of pixels Spix allocated to viewpoint E(t±η) within the pixel Spix located within slit 21a. Furthermore, as described above, the light passing through the pixel Spix allocated to viewpoint E(t) within the pixel Spix located within slit 21a is light L(t). Additionally, the light passing through the pixel Spix allocated to viewpoint E(t±η) within the pixel Spix located within slit 21a is naturally light L(t±η).

[0112] Figure 22 This is a graph showing the ratio of light L(t) to light L(t±η) in the output examples F1, F2, F3, F4, and F5 of five different modes, representing the relationship between the ratio of light L(t) to light L(t±η) in the light passing through slit 21a.

[0113] Compared to output examples F2, F3, F4, and F5, output example F1 has a higher proportion of light L(t) and a higher proportion of light L(t±1). Particularly in output example F1, the light up to light L(t±2) accounts for approximately 100% of the light transmitted through slit 21a. Output example F2 has a higher proportion of light L(t) and a higher proportion of light L(t±1) compared to output examples F3, F4, and F5. Output example F3 has a higher proportion of light L(t) and a higher proportion of light L(t±1) compared to output examples F4 and F5. Output example F4 has a higher proportion of light L(t) and a higher proportion of light L(t±1) compared to output example F5.

[0114] Figure 23 The output examples F1, F2, F3, F4, and F5 are used to represent the values ​​based on... Figure 22 The diagram shows the relationship between the proportion of light L(t) and the proportion of light L(t±η) in each of the five output modes F1, F2, F3, F4, and F5, and the resulting visual recognition image at viewpoint E(t). Figure 23 As the example shows, the higher the proportion of light L(t), the clearer the image outline can be recognized at the viewpoint E(t). Even if the proportion of light L(t) decreases, since light L(t±η) also functions to complement light L(t) through the mutual complementation described above, the image accuracy is maintained to a minimum in every output example. However, in output examples where light L(t±3 or more) accounts for the majority (e.g., output example F5), the image is still blurry compared to output examples where light L(t±3 or more) is less abundant.

[0115] Considering the reference Figure 22 as well as Figure 23 The phenomenon described indicates that a higher proportion of light L(t) passes through slit 21a. For example, refer to... Figures 5 to 11 The example described is roughly equivalent to output example F1. Furthermore, when the proportion of light L(t) in the light passing through slit 21a is 9.1% or more, excessive blurring can be suppressed. Moreover, by making the proportion of light L(t) in the light passing through slit 21a 16.7% or more, a more accurate visual recognition image can be obtained.

[0116] Furthermore, if reference is taken Figure 8 The width D1 of the slit 21a in the first direction Dx is set to, for example, the width D4 of the first direction Dx of a pixel Spix (see reference). Figure 6 If the width D1 is less than the width D4, the proportion of light L(t) in the light passing through slit 21a decreases. Therefore, by making the width D1 less than the width D4, the proportion of light L(t) in the light passing through slit 21a can be further increased. However, if the width D1 is set to be greater than or equal to the width D4, the total amount of light passing through slit 21a increases compared to the case where the width D1 is less than the width D4, thus improving the brightness of the visually recognized image.

[0117] As described above, according to the structure of this disclosure, it includes: a display panel (e.g., display panel 10) having a plurality of pixels (pixels) configured in a matrix; and a dimming panel (e.g., dimming panel 20) such that the light from the display panel toward a plurality of viewpoints (e.g., viewpoints E(n) and E(n+1) or viewpoints E(1), ..., E(r)) is different on a viewpoint basis, the plurality of pixels including a first pixel (e.g., first pixel Rpix) that outputs light of a first color and a second pixel (e.g., second pixel Gpix) that outputs light of a second color, the first pixel and the second pixel being arranged in a column direction (second direction Dy) orthogonal to the arrangement direction of the plurality of viewpoints, the width (e.g., width D4) of the pixel in the row direction (first direction Dx) along the arrangement direction of the plurality of viewpoints is greater than the width (e.g., width D3) in the column direction.

[0118] Therefore, even if light from multiple pixels (pixels) arranged in the row direction (first direction Dx) reaches different viewpoints, since first pixels (e.g., first pixel Rpix) and second pixels (e.g., second pixel Gpix) are arranged in the column direction (second direction Dy), light of various colors from multiple pixels (pixels) can reach each viewpoint more reliably. Thus, undesirable shading can be further suppressed.

[0119] Furthermore, since there are multiple pixels (pixels) of the output image assigned to a viewpoint (viewpoint E(t)) in a column direction (second direction Dy), it is possible to further increase the proportion of light L(t) in the light passing through slit 21a.

[0120] Furthermore, the dimming panel (e.g., dimming panel 20) has a light-shielding portion (light-shielding portion 21) for blocking light and a slit (slit 21a) provided in the light-shielding portion. As a result, the dimming panel can be constructed with a simple structure.

[0121] Furthermore, the slit (slit 21a) is tilted relative to the row direction (first direction Dx) and the column direction (second direction Dy), and the tilt angle (acute angle θ2) relative to the column direction is smaller than the tilt angle (acute angle θ1) relative to the row direction. As a result, moiré fringes can be suppressed more reliably.

[0122] Furthermore, the dimming panel (dimming panel 20A, 20B) has a lens (lens 24) that converges light from pixels (pixels) that are assigned the output of an image for a viewpoint (viewpoint E(t)) to that viewpoint. This further improves the utilization efficiency of light from that pixel.

[0123] Furthermore, the dimming panel (dimming panel 20C) has a liquid crystal panel that is configured to form a light-blocking area and a light-transmitting area. This allows the display panel (e.g., display panel 10) to switch between a first mode that outputs individual images to multiple viewpoints as described above, and a second mode that outputs a single image across the entire surface of the display area AA without limiting the viewpoints. In the second mode, the liquid crystal panel of the dimming panel is controlled to use its entire surface as a light-transmitting area.

[0124] In addition, a signal processing unit (signal processing unit 30) is provided, which distributes data to multiple pixels in such a way that the light arriving at each of the multiple viewpoints (viewpoints E(1), ..., E(r)) becomes light from a pixel (pixel Spix) that outputs light constituting an image corresponding to each of the multiple viewpoints. The signal processing unit provides an output image (output image OP) generated based on multiple input images (input images IP(1), ..., input images IP(r)) corresponding to each of the multiple viewpoints to a display panel (e.g., display panel 10). The output image includes multiple partial regions (e.g., partial regions P), which are formed by rearranging data (e.g., extraction ranges PU(1), PU(2), PU(3), ...) corresponding to a portion of each of the multiple input images in the column direction (second direction Dy) according to the arrangement order of the multiple viewpoints. Thus, if the multiple input images are prepared, the image corresponding to the multiple viewpoints can be output through the display panel.

[0125] Furthermore, r can be any natural number greater than 2. Additionally, η is a natural number.

[0126] Furthermore, any other effects resulting from the configuration described in this embodiment should be understood as being derived from this disclosure, based on the explicit content of this specification or as that which can be reasonably conceived by those skilled in the art.
