Description

Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular to a display screen and a display terminal. Background Art

[0002] With the continuous development of display technology, three-dimensional (3D) display screens are increasingly widely used to display images. Compared with traditional flat-panel display screens, the sub-pixels of 3D display screens not only have three different colors: red (red, R), green (green, G) and blue (blue, B), but also the sub-pixels have angle selectivity in luminescence, and different sub-pixels correspond to different luminescence angles. When an observer watches a 3D display screen, the positions and angles of the left and right eyes are different relative to the 3D display screen, or when the observer's position and angle of viewing the 3D display screen are different, different images can be observed. Different images correspond to the information observed at different angles of the same display content (such as an object), giving people a 3D sense of space.

[0003] However, in the related two-dimensional 3D display screen, the optical structure is mainly covered on the display screen. In this way, the sub-pixels covered by different optical structures can emit light through the corresponding optical structures, and the light beams point to different directions, while the light beams of the sub-pixels covered by different optical structures at relatively the same position all point to the same direction. In other words, the sub-pixels with light beams pointing to the same direction are sub-pixels with the same color and the same light-emitting angle, while the sub-pixels with light beams pointing to different directions are sub-pixels with different colors. This will cause color deviation or color stripes when observers view the same display screen at different angles.

[0004] Therefore, how to prevent an observer from observing color shift changes and color stripes when viewing the display screen at different angles has become a problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a display screen and a display terminal, and an observer can observe an image corresponding to the complete RGB colors from viewing angles corresponding to different viewpoints without any color loss or stripes.

[0006] In a first aspect, an embodiment of the present application provides a display screen. The display screen includes a preset sub-pixel array composed of a first sub-pixel unit including M×N sub-pixels in a repeated order, and the preset sub-pixel array is divided into K second sub-pixel units, each second sub-pixel unit includes U×V sub-pixels, wherein U is not equal to an integer multiple of M or V is not equal to an integer multiple of N, M, N, U, and V are all positive integers, and K≥3. The sub-pixel at the first position of the second sub-pixel unit is mapped to a first viewpoint in a preset visible area, and the first viewpoint is a viewpoint in the preset visible area. The color of the sub-pixel at the first position in the second sub-pixel unit is any one of the red, green, blue, and RGB colors, and the colors of the K sub-pixels at the first position constitute the RGB color. In the embodiment of the present application, by re-dividing the preset sub-pixel array constituting the display screen into units, for the K second sub-pixel units obtained after the division, U×V sub-pixels in each second sub-pixel unit are respectively mapped to viewpoints in the preset visible area, so that the sub-pixels at the first position in each second sub-pixel unit can be mapped to the same viewpoint, and the colors of the sub-pixels at the first position in the K second sub-pixel units can form a complete RGB color. In this way, at different viewpoints, the observer can observe the image corresponding to the complete RGB color from the observation angle or observation position corresponding to the different viewpoints, without color loss or stripes.

[0007] In some possible implementations, the display screen further includes a first optical structure, and the second sub-pixel unit is covered by the first optical structure.

[0008] In some possible implementations, the display screen further includes a second optical structure, and each sub-pixel in the second sub-pixel unit is covered by the second optical structure.

[0009] In some possible implementations, central light beams of light emitted by sub-pixels at the first position of the second sub-pixel unit intersect at the first viewpoint.

[0010] In some possible implementations, a central light beam emitted by a sub-pixel at a first position of the second sub-pixel unit points in parallel to the first viewpoint.

[0011] In some possible implementations, the preset visible area includes a visible plane, a visible spherical surface, or a visible curved surface.

[0012] In some possible implementations, the preset sub-pixel array includes a zigzag sub-pixel arrangement Rainbow RGB, a staggered sub-pixel arrangement Pentile RGGB, a triangle sub-pixel arrangement RGB Delta, or a stripe sub-pixel arrangement RGBstrip. The arrangement of multiple preset sub-pixel arrays such as the Rainbow RGB screen, the Pentile RGGB screen, the RGB Delta screen, and the RGB strip screen can be applied to a wide range of screen types.

[0013] In a second aspect, an embodiment of the present application provides a display terminal, which includes at least one processor and a display screen as described in the first aspect and any possible implementation of the first aspect.

[0014] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:

[0015] In the embodiment of the present application, by re-dividing the preset sub-pixel array constituting the display screen into units, for the K second sub-pixel units obtained after the division, U×V sub-pixels in each second sub-pixel unit are respectively mapped to viewpoints in the preset visible area, so that the sub-pixels at the first position in each second sub-pixel unit can be mapped to the same viewpoint, and the colors of the sub-pixels at the first position in the K second sub-pixel units can form a complete RGB color. In this way, at different viewpoints, the observer can observe the image corresponding to the complete RGB color from the viewing angle corresponding to the different viewpoints, and there will be no color loss or stripes.

[0034] The embodiments of the present application provide a display screen and a display terminal, and an observer can observe an image corresponding to complete RGB colors from viewing angles corresponding to different viewpoints without any color loss or stripes.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the implementation of the application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. In this application, "at least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following items (individuals)" or similar expressions thereof refer to any combination of these items, including any combination of single items (individuals) or plural items (individuals). For example, at least one of a, b or c can mean: a, b, c, a and b, a and c, b and c or a and b and c, where a, b and c can be single or multiple. It is worth noting that "at least one" can also be interpreted as "one or more".

[0037] With the continuous development of display technology, display screens are increasingly used to display images. Figure 1 This is a schematic diagram of an application scenario provided by this application. Figure 1As shown, the display screen 10 is located in the x, y plane of z=0, and the light beams emitted by the sub-pixels constituting the display screen 10 have angle selectivity, and the observer can only observe the corresponding sub-pixels within a certain angle range. These observation positions can be understood as certain viewpoints 201 (such as; viewpoint 1, viewpoint 2...) at different angles (θ, ψ) with the display screen 10 in the preset visible area 20 in the z>0 space. The observer can see the image composed of sub-pixels based on the observation positions or observation angles corresponding to these viewpoints. When the observer views the display screen 10, the positions and angles of the left and right eyes are different relative to the display screen 10, or when the observer views the display screen 10 at different positions and angles, different images can be observed. Different images correspond to the information observed at different angles of the same display content (such as an object), so that people have a 3D sense of space.

[0038] However, in the related two-dimensional 3D display screen 10, the optical structure 101 is mainly covered on the display screen 10, so that the sub-pixels 102 on the display screen can emit light through the optical structure 101. Figure 2 , is a schematic diagram of a light beam pointing of a sub-pixel 102 provided in a related solution. Figure 2 It can be seen that the display screen 10 can be composed of sub-pixels 102 that are repeatedly arranged according to a certain rule. For example, the three sub-pixels 102 of R, G, and B form the smallest repeating unit, and are repeatedly arranged in sequence. Every two repeating units can be divided into one unit, and an optical structure 101 is used to cover the sub-pixels 102 under one unit. In this way, the sub-pixels 102 covered by different optical structures 101 can emit light through the corresponding optical structures 101, and the light beams point to different directions. For the sub-pixels 102 at the same position in each unit, since the colors of the sub-pixels 102 are the same, the light beams enabled by different optical structures 101 all point to the same direction. Figure 2As shown in the figure, for example, the three sub-pixels 102 of R, G, and B form the smallest repeating unit, and are repeatedly arranged in the horizontal direction. Each divided unit a and unit b can include 6 sub-pixels 102. The optical structure 101 covers the 6 sub-pixels 102 in unit a, and the light beams emitted by these 6 sub-pixels 102 point to directions ① to ⑥ respectively. The optical structure 101 covers the 6 sub-pixels 102 in unit b, and the light beams emitted by these 6 sub-pixels 102 also point to directions ① to ⑥ respectively. It can be clearly seen that for the sub-pixel 102 at the first position in unit a (i.e., R) and the sub-pixel 102 at the first position in unit b (i.e., R), the light beams emitted by these two sub-pixels 102 point to the same direction ⑥. The directions pointed to by the sub-pixels 102 at the remaining positions in units a and b can also be understood with reference to the sub-pixel 102 at the first position.

[0039] In other words, in the relevant two-dimensional 3D display screen 10, the sub-pixels 102 with light beams pointing in the same direction are sub-pixels with the same color and the same light-emitting angle, while the sub-pixels 102 with light beams pointing in different directions are sub-pixels with different colors. This will result in color deviation or color stripes when observers view the same display screen 10 at different angles.

[0040] In order to solve the above-mentioned problems such as color deviation or color stripes when viewed at different angles, the present application provides a display screen 10. The display screen 10 can be applied to a display terminal, and the display screen 10 also includes at least one processor. For example, the display terminal can be a user equipment (UE), a mobile station (MS), a mobile terminal (mobile terminal), a computer, a television, a projector, a mobile phone (or a "cellular" phone), a mobile computer, a computer with a mobile terminal, a smart watch, a mobile device mounted on a vehicle, etc.

[0041] Figure 3 A schematic diagram of the structure of a display screen provided in an embodiment of the present application.

[0042] like Figure 3As shown, the display screen 10 includes a preset sub-pixel array 104 composed of a first sub-pixel unit 103 including M×N sub-pixels 102 that are repeatedly arranged. The preset sub-pixel array 104 is divided into K second sub-pixel units 105, each of which includes U×V sub-pixels 102, wherein U is not equal to an integer multiple of M or V is not equal to an integer multiple of N, M, N, U, and V are all positive integers, and K≥3. The sub-pixel 102 at the first position of the second sub-pixel unit 105 is mapped to a first viewpoint in the preset visible area 20, and the first viewpoint is a viewpoint 201 in the preset visible area 20. The color of the sub-pixel 102 at the first position in the second sub-pixel unit 105 is any one of the red, green, blue, and RGB colors, and the colors of the K sub-pixels 102 at the first position constitute the RGB color.

[0043] In this example, the first sub-pixel unit 103 includes M×N sub-pixels 102, that is, the first sub-pixel unit 103 sequentially arranges M sub-pixels 102 in the horizontal direction and N sub-pixels 102 in the vertical direction. In this way, the first sub-pixel unit 103 is used as the minimum repeating unit constituting the preset sub-pixel array 104, and the preset sub-pixel array 104 is obtained by repeatedly arranging in the horizontal direction and the vertical direction. For example, from Figure 3 As can be seen from the portion (A) shown, the first sub-pixel unit 103 includes 3×6 sub-pixels 102, and 8 first sub-pixel units 103 are repeatedly arranged in the horizontal direction (eg, x), and 2 first sub-pixel units 103 are repeatedly arranged in the vertical direction (eg, y). It should be noted that Figure 3 The preset sub-pixel array 104 composed of 8×2 first sub-pixel units 103 shown in part (A) is only a schematic description. In practical applications, there is no limit on the number of first sub-pixel units 103 that are repeatedly arranged in the horizontal direction x and the vertical direction y of the preset sub-pixel array 104.

[0044] For each first sub-pixel unit 103, since the colors of the sub-pixels 102 at the same position in each first sub-pixel unit 103 are the same color in RGB, such as R (red), G (green) or B (blue), if the sub-pixels 102 at the same position in each first sub-pixel unit 103 are continuously mapped to the same viewpoint 201, the above-mentioned Figure 2 The problem of color deviation or stripes observed at the same angle as described in Figure 3It can be seen from the portion (A) shown that in the preset sub-pixel array 104 composed of 8×2 first sub-pixel units 103, for each first sub-pixel unit 103, the color of the sub-pixel 102 at the same sorting position a is R, i.e., red; or the color of the sub-pixel 102 at the same sorting position b is G, i.e., green. By analogy, it can be known that the color of the sub-pixel 102 at the same first position (such as sorting position a or sorting position b, etc.) of each first sub-pixel unit 103 is only one of the RGB colors.

[0045] Therefore, on the basis of the preset sub-pixel array 104, the preset sub-pixel array 104 is re-divided into sub-pixel units, that is, the preset sub-pixel array 104 is divided into K second sub-pixel units 105, and each second sub-pixel unit 105 contains U×V sub-pixels 102. The size of the second sub-pixel unit 105 is neither equal to the size of the first sub-pixel unit 103 nor equal to a multiple of the size of the first sub-pixel unit 103, that is, U is not equal to an integer multiple of M or V is not equal to an integer multiple of N, and M, N, U, and V are all positive integers. For different display screens 10, the M×N sub-pixels 102 contained in the first sub-pixel unit 103 may also be different. Therefore, the mentioned U is not equal to an integer multiple of M or V is not equal to an integer multiple of N can be further understood as:

[0046]

[0047] For example, from the Figure 3 As can be seen from part (B), the Figure 3 The preset sub-pixel array 104 shown can be divided into 9 second sub-pixel units 105, and each second sub-pixel unit 105 includes 8×4 sub-pixels 102. Specifically, it is divided into 3 second sub-pixel units 105 in the horizontal direction x, and divided into 3 second sub-pixel units 105 in the vertical direction y. Each second sub-pixel unit 105 includes 8×4 sub-pixels 102, that is, the second sub-pixel unit 105 has 8 sub-pixels 102 arranged in sequence in the horizontal direction x, and 4 sub-pixels 102 arranged in sequence in the vertical direction y. It should be noted that for Figure 3 The predetermined sub-pixel array 104 shown in part (A) of FIG. 1 is composed of a first sub-pixel unit 103 including 3×6 sub-pixels 102 repeatedly arranged, except that the first sub-pixel unit 103 is divided into Figure 3 In addition to the second sub-pixel unit 105 including 8×4 sub-pixels 102 shown in part (B), it can also be divided into other second sub-pixel units 105 including U×V sub-pixels 102, as long as U is not equal to an integer multiple of 3 and V is not equal to an integer multiple of 6. For details, please refer to the contents of the following Table 1:

[0048] Table 1

[0049]

[0050] It can be seen from Table 1 that the second sub-pixel unit 105 may include not only 8×4 sub-pixels 102, but also 14×7 sub-pixels 102, or 16×8 sub-pixels 102, or 7×8 sub-pixels 102, etc., which is not limited here.

[0051] In addition, the preset visible area 20 described is composed of U×V viewpoints 201, which means that the number of viewpoints 201 is the same as the number of sub-pixels 102 in each second sub-pixel unit 105. Moreover, the observer can see the complete image on the display screen 10 from the observation positions or observation angles corresponding to different viewpoints 201. For example, Figure 4 FIG. 1 shows a schematic diagram of viewpoint arrangement in a preset visual area provided by an embodiment of the present application. Figure 4 As shown, the preset visual area 20 includes 8×4 viewpoints 201 (i.e., viewpoint 1 to viewpoint 32), that is, 8 viewpoints 201 are arranged in the horizontal direction x, and 4 viewpoints 201 are arranged in the vertical direction y. It should be noted that the first viewpoint mentioned is a viewpoint in the U×V viewpoints 201, but the first viewpoint is not limited to Figure 4 The viewpoint 1 shown in FIG. 1 may also be other viewpoints 201 in practical applications, such as viewpoint 2, viewpoint 10, etc., which are not limited here.

[0052] In addition, the aforementioned preset visible area 20 can be understood as the observation position and angle range in which the observer can observe the complete image on the display screen 10 in the design, that is, the position range where the aforementioned viewpoint 201 is located. The preset visible area 20 can correspond to a visible plane, a visible sphere or a visible curved surface. This is not limited in the embodiments of the present application. It should be noted that when the observer is not observing at the viewpoint 201 position within the preset visible area 20, for example: when observing at a position closer or farther from the preset visible area 20, it is still possible to observe the image on the display screen 10.

[0053] The first position in each second sub-pixel unit 105 is the same, which can be understood as the same sorting position of the sub-pixel 102 in each second sub-pixel unit 105. Moreover, the sorting position can be understood as the position arranged in the horizontal direction x and the vertical direction y. For example, Figure 3The sorting position c shown in part (B) can be understood as the first position mentioned above. It should be noted that in practical applications, the first position in each second sub-pixel unit 105 is not limited to the first sorting position (i.e., sorting position c) of the sub-pixels 102 arranged in the horizontal direction x and the vertical direction y, and may also include but is not limited to other sorting positions.

[0054] In this way, after the preset sub-pixel array 104 is divided into K second sub-pixel units 105, the colors of the sub-pixels 102 at the first positions of the second sub-pixel units 105 are all any one of the RGB colors, and the colors of all the sub-pixels 102 at the first positions constitute a complete RGB color. Then, the sub-pixels 102 at the first positions of the K second sub-pixel units 105 are mapped to the first viewpoint in the preset visible area 20, and the observer can observe the image corresponding to the complete RGB color at the first viewpoint.

[0055] For example, from the Figure 3 As can be seen from the (B) part, in the divided 9 second sub-pixel units 105, each second sub-pixel unit 105 includes 8×4 sub-pixels 102. The colors of the sub-pixels 102 at the same sorting position c of these 9 second sub-pixel units 105 are all one of the RGB colors, and constitute a complete RGB color. For details, please refer to Figure 5A , which is a schematic diagram of mapping a sub-pixel 102 to an image observed at a first viewpoint, provided in an embodiment of the present application. Figure 5A It can be seen that if in each second sub-pixel unit 105, Figure 3 The sort position c shown in part (B) is taken as the first position, Figure 4 Taking the middle viewpoint 1 as the first viewpoint as an example, the sub-pixels 102 at the sorting position c in the 3×3 second sub-pixel units 105 can all be mapped to the above Figure 4 See also Viewpoint 1 in Figure 5B , is a schematic diagram of an image observed at a first viewpoint provided by the present application. Figure 5B It can be seen that when viewpoint 1 is used as the first viewpoint, the light beams emitted by the sub-pixels 102 at the sorting position c in the nine second sub-pixel units 105 can be seen at viewpoint 1, and the colors of the sub-pixels 102 at the nine sorting positions c are R, B, G, G, R, B, G, R, B from left to right. That is, the complete image composed of the sub-pixels 102 at the nine sorting positions c can be seen at viewpoint 1.

[0056] That is to say, the present application re-divides the preset sub-pixel array 104 into units, and for the K second sub-pixel units 105 obtained after the division, the U×V sub-pixels 102 in each second sub-pixel unit 105 are respectively mapped to U×V viewpoints 201, so that the sub-pixels 102 at the first position in the second sub-pixel unit 105 can be mapped to the same viewpoint 201, and the sub-pixels 102 at different positions are mapped to different viewpoints 201, and the colors of the sub-pixels 102 at different positions in the K second sub-pixel units 105 can form a complete RGB color. In this way, at different viewpoints 201, the observer can observe the image corresponding to the complete RGB color from the observation angles corresponding to the different viewpoints 201, and there will be no color loss or stripes.

[0057] In some optional examples, the display screen 10 may further include a first optical structure 106. The second sub-pixel unit 105 is covered by the first optical structure 106. That is, in the above Figure 3 On the basis of the display screen 10 described above, a first optical structure 106 can be provided for each second sub-pixel unit 105 to achieve beam convergence and deflection. In this way, each first optical structure 106 can refract the central light beam (chief ray) emitted by the sub-pixel 102 at the first position in the second sub-pixel unit 105 covered by each of them to the same viewpoint 201, and refract the central light beam emitted by the sub-pixel 102 at different positions to different viewpoints 201.

[0058] For example, Figure 6 The structure of the display screen 10 shown in FIG. 1 illustrates the relationship between the second sub-pixel unit 105 and the first optical structure 106. Figure 6 It can be seen that the display screen 10 includes three first optical structures 106 (i.e., 1061, 1062, and 1063) and three second sub-pixel units 105 (i.e., 1051, 1052, and 1053), and each second sub-pixel unit 105 includes 4×1 sub-pixels 102. Among them, 1061 covers 1051, 1062 covers 1052, and 1063 covers 1053. And, from Figure 6It can also be seen that after the sub-pixels 102 (i.e., R, G, B) at the first position of 1051, 1052, and 1053 are refracted by 1061, 1062, and 1063, the central light beams emitted by each of them point to the direction ④. That is, the sub-pixels 102 (i.e., R, G, B) at the first position of 1051, 1052, and 1053 can be mapped to the viewpoint 201 corresponding to the direction ④ after being enabled by 1061, 1062, and 1063. Similarly, after the sub-pixels 102 (i.e., G, B, R) at the second position of 1051, 1052, and 1053 are refracted by 1061, 1062, and 1063, the central light beams emitted by each of them point to the direction ③. By analogy, the sub-pixels 102 at different positions can be mapped to different viewpoints 201 through different first optical structures 106.

[0059] It should be noted that for the above Figure 3 The nine second sub-pixel units 105 described in part (B) may also be configured with corresponding nine first optical structures 106. Figure 6 The contents described above can be understood and will not be elaborated here. Figure 6 The first optical structure 106 described includes but is not limited to a microlens array, a pinhole array, a barrier, a directional backlight source, etc., which are not limited here.

[0060] In some other optional examples, the display screen 10 may further include a second optical structure 107. Each sub-pixel 102 in the second sub-pixel unit 105 is covered by the second optical structure 107. That is, in the above Figure 3 On the basis of the display screen 10 described above, a second optical structure 107 may be separately matched for each sub-pixel 102 in the second sub-pixel unit 105. In this way, in the second sub-pixel unit 105, the central light beam emitted by the sub-pixel 102 at the corresponding first position may be refracted to the same viewpoint 201 through each second optical structure 107, and the central light beam emitted by the sub-pixel 102 at different positions may be refracted to different viewpoints 201.

[0061] For example, Figure 7 The structure of the display screen 10 shown in FIG. 1 illustrates the relationship between the second sub-pixel unit 105 and the second optical structure 107. Figure 7It can be seen that the display screen 10 includes three second sub-pixel units 105 (i.e., 1051, 1052, and 1053), and each second sub-pixel unit 105 includes 4×1 sub-pixels 102. That is, 1051 includes four sub-pixels 102, namely, R1, G1, B1, and R2, 1052 includes four sub-pixels 102, namely, G2, B2, R3, and G3, and 1053 includes four sub-pixels 102, namely, B3, R4, G4, and B4. Moreover, the display screen 10 also includes 12 second optical structures 107 (i.e., 1071 to 10712). Among them, 1071 covers R1, 1072 covers G1, and so on according to the arrangement order of the sub-pixels 102, and 10712 covers B4. Moreover, from Figure 7 It can also be seen that after the sub-pixels 102 (i.e., R1, G2, B3) at the first position in 1051, 1052, and 1053 are refracted by 1071, 1075, and 1079, the central light beams emitted by each of them point to the direction ①. That is, the three sub-pixels 102 R1, G2, and B3 can be mapped to the viewpoint 201 corresponding to the direction ① under the enabling action of 1071, 1075, and 1079, respectively. Similarly, after the sub-pixels 102 (i.e., G1, B2, R4) at the second position in 1051, 1052, and 1053 are refracted by 1072, 1076, and 10710, the central light beams emitted by each of them point to the direction ②. By analogy, the sub-pixels 102 at different positions can be mapped to different viewpoints 201 through different second optical structures 107.

[0062] Regarding the aforementioned Figure 3 Each sub-pixel 102 in the second sub-pixel unit 105 described in part (B) may also be configured with a corresponding second optical structure 107. Figure 7 The contents described above can be understood and will not be elaborated here. Figure 7 The second optical structure 107 described includes but is not limited to a refractive structure or a diffractive structure.

[0063] In some optional examples, since the observer can observe the complete image on the display screen 10 at the viewpoint 201 of the preset visual area 20. The viewpoint 201 in the preset visual area 20 can be located at infinity and corresponds to a corresponding observation angle; it can also be a corresponding observation position in space that can be observed by the human eye. Different viewpoints 201 correspond to different observation angles or observation positions. Therefore, when the first viewpoint is located at an observation position visible to the human eye, the central light beams of the sub-pixels 102 at the first position of the second sub-pixel unit 105 intersect at the first viewpoint, thereby realizing the mapping of the sub-pixels 102 at the first position of the second sub-pixel unit 105 to the first viewpoint. Alternatively, when the first viewpoint is located at a certain observation angle at infinity, the central light beams of the sub-pixels 102 at the first position of the second sub-pixel unit 105 can be parallel to the first viewpoint.

[0064] from Figure 3 As can be seen from part (A), 3×6 sub-pixels 102 are used as the first sub-pixel unit 103 (i.e., understood as the minimum repeating unit), and the first sub-pixel unit 103 is repeatedly arranged in the horizontal direction x and the vertical direction y, which only describes the preset sub-pixel array 104 corresponding to the display screen 10 when it is a Rainbow RGB screen, i.e., the zigzag sub-pixel arrangement Rainbow RGB. In actual applications, the display screen 10 is not limited to only including Figure 3 The preset sub-pixel array 104 shown in part (A) may also include, but is not limited to, a preset sub-pixel array 104 corresponding to a Pentile RGGB screen, an RGB Delta screen, or an RGB strip screen, that is, a staggered sub-pixel arrangement PentileRGGB corresponding to a Pentile RGGB screen, a triangular sub-pixel arrangement RGB Delta corresponding to an RGB Delta screen, or a stripe line sub-pixel arrangement RGB strip corresponding to an RGB strip screen, which is not limited here. It should be noted that the staggered sub-pixel arrangement PentileRGGB mentioned may be just a Chinese name for the sub-pixel array corresponding to the Pentile RGGB screen. In actual applications, other Chinese names may be used instead, which is not limited here. Similarly, other Chinese names may also be used to replace the zigzag sub-pixel arrangement Rainbow RGB, the triangular sub-pixel arrangement RGB Delta, or the stripe line sub-pixel arrangement RGB strip, which is not limited here.
