Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] With the continuous development of display technology, display panels have been widely used in people's production and daily life. However, there are still some technical problems in existing display panels that need to be solved. For example, in existing display panels that combine privacy and shared display modes, the aperture ratio of the display panel is relatively low, which affects the display effect (such as brightness) and lifespan of the display panel. Summary of the Invention

[0003] This invention provides a display panel and a display device to improve the aperture ratio of the display panel, optimize the display effect, and extend the service life of the display panel while taking into account both privacy protection and shared display modes.

[0004] According to one aspect of the present invention, a display panel is provided, comprising: a plurality of first pixel units and a plurality of second pixel units; the first pixel units and the second pixel units are arranged in an array along a first direction and a second direction; the first direction and the second direction intersect. The first pixel unit includes at least one shared pixel group; the shared pixel group includes the first pixel group; in the first pixel group, the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the second color sub-pixel are arranged sequentially along the first direction; The second pixel unit includes at least one privacy pixel group; the privacy pixel group includes a second pixel group; in the second pixel group, the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the second color sub-pixel are arranged sequentially along the first direction; Shared pixel groups and privacy pixel groups are arranged alternately along the second direction; in the i-th shared pixel group and the j-th privacy pixel group, sub-pixels of the same color overlap along the second direction; i=j≥1 and are positive integers; The display panel includes a sharing mode and a privacy mode; in sharing mode, at least the first pixel unit is illuminated; in privacy mode, the second pixel unit is illuminated, and the first pixel unit is not illuminated.

[0005] According to another aspect of the present invention, a display device is provided, comprising a display panel provided in any embodiment of the present invention.

[0006] The technical solution of this invention optimizes pixel arrangement by setting the first pixel unit that emits light in shared mode to include at least one shared pixel group, and the second pixel unit that emits light in privacy mode to include at least one privacy pixel group. Along the second direction, the shared pixel group and the privacy pixel group are arranged alternately. In the i-th shared pixel group and the j-th (j=i) privacy pixel group, the sub-pixels of the same color overlap along the second direction. For example, the shared pixel group in the first pixel unit includes at least the first pixel group, and the privacy pixel group in the second pixel unit includes at least the second pixel group. The sub-pixels in the first pixel group and the second pixel group are arranged sequentially in the first direction in the order of first color sub-pixel, second color sub-pixel, third color sub-pixel, and second color sub-pixel. In this way, adjacent pixels can share the first color sub-pixel and / or the third color sub-pixel, reducing the number of sub-pixels in the display panel, increasing the aperture ratio, increasing brightness, optimizing the display effect, and extending the service life of the display panel. It can also make the privacy sub-pixels and shared sub-pixels evenly distributed in the display panel, ensuring the display effect of both shared mode and privacy mode.

Detailed Implementation

[0010] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0011] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0012] First, it should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. The terms "comprising" and similar terms mean that the element or object preceding the word encompasses the element or object listed after the word and its equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described object changes. Furthermore, the shapes and sizes of the components in the accompanying drawings do not reflect actual proportions and are only intended to illustrate the content of this invention.

[0013] In existing display panels, such as medium and large-sized display panels, the R, G, and B (red, green, and blue) subpixels often adopt a real arrangement such as π arrangement, meaning that each pixel P independently has one R subpixel, one G subpixel, and one B subpixel. With this pixel arrangement, if the display panel has both shared and privacy display modes, the privacy subpixels typically require light-blocking structures to block light from escaping at wide viewing angles to achieve the privacy function. This results in a larger spacing between adjacent pixels, a lower aperture ratio for the display panel, and consequently affects the display effect and lifespan.

[0014] This invention provides a display panel and a display device that, while supporting both shared and privacy display modes, optimizes pixel arrangement to increase the aperture ratio of the display panel, thereby improving display performance and extending the lifespan of the display panel. The technical solutions in this invention will be explained below with reference to the accompanying drawings.

[0015] For example, Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 The diagram shown illustrates the display panel in shared mode. Figure 3 yes Figure 1 The diagram shown illustrates the display panel in privacy mode. (Refer to...) Figure 1 The display panel 100 provided in this embodiment of the invention includes a plurality of first pixel units 110 and a plurality of second pixel units 120; the first pixel units 110 and the second pixel units 120 are both arranged in an array along a first direction X and a second direction Y; the first direction X and the second direction Y intersect; the first pixel unit 110 includes at least one shared pixel group 10; the shared pixel group 10 includes a first pixel group 10a; in the first pixel group 10a, a first color sub-pixel 101, a second color sub-pixel 102, a third color sub-pixel 103, and a second color sub-pixel 102 are arranged sequentially along the first direction X; the second pixel... Unit 120 includes at least one privacy pixel group 20; the privacy pixel group 20 includes a second pixel group 20a; in the second pixel group 20a, a first color sub-pixel 101, a second color sub-pixel 102, a third color sub-pixel 103, and the second color sub-pixel 102 are arranged sequentially along a first direction X; the shared pixel group 10 and the privacy pixel group 20 are arranged alternately along a second direction Y; in the i-th shared pixel group 10-i and the j-th privacy pixel group 20-j, sub-pixels of the same color overlap along the second direction Y; i=j≥1 and are positive integers; the display panel 100 includes a shared mode and a privacy mode; see reference Figure 2 In shared mode, at least the first pixel unit 110 emits light; refer to Figure 3 In privacy mode, the second pixel unit 120 emits light, while the first pixel unit 110 does not emit light.

[0016] The privacy mode refers to a mode where the displayed content is clearly visible only from a small, frontal angle, and not visible from a large side angle, preventing others from peeping at the displayed content. In privacy mode, only the second pixel unit 120 emits light, while the first pixel unit 110 does not. The sharing mode, however, does not actively prevent others from peeping at the displayed content. In sharing mode, only the first pixel unit 110 may emit light, or both the first pixel unit 110 and the second pixel unit 120 may emit light to increase brightness in sharing mode. This embodiment of the invention only illustrates the example of the first pixel unit 110 emitting light and the second pixel unit 120 not emitting light in sharing mode.

[0017] Reference Figure 1 and Figure 2 The first pixel unit 110 refers to a minimum repeating unit of all shared sub-pixels (sub-pixels that emit light in the shared mode). The first pixel unit 110 is arranged in a periodic array along the first direction X and the second direction Y.

[0018] Specifically, the first pixel unit 110 includes one or more shared pixel groups 10, and the sub-pixels in each shared pixel group 10 are arranged along the first direction X. When the first pixel unit 110 includes two or more shared pixel groups 10, each shared pixel group 10 in the first pixel unit 110 is arranged along the second direction Y.

[0019] For example, Figure 1 and Figure 2 Taking the first pixel unit 110 as an example, which includes a shared pixel group 10 (first pixel group 10a), the first pixel group 10a includes a first color sub-pixel 101, two second color sub-pixels 102 and a third color sub-pixel 103. Along the first direction X, these four sub-pixels are arranged in the order of first color sub-pixel 101, second color sub-pixel 102, third color sub-pixel 103 and second color sub-pixel 102.

[0020] Reference Figure 1 and Figure 3 The second pixel unit 120 refers to a minimum repeating unit of all privacy sub-pixels (sub-pixels that emit light in privacy mode). The second pixel unit 120 is arranged in a periodic array along the first direction X and the second direction Y.

[0021] Specifically, the second pixel unit 120 includes one or more privacy pixel groups 20, and the sub-pixels in each privacy pixel group 20 are arranged along the first direction X. When the second pixel unit 120 includes two or more privacy pixel groups 20, the privacy pixel groups 20 in the second pixel unit 120 are arranged along the second direction Y.

[0022] For example, Figure 1 and Figure 3 Taking the second pixel unit 120 as an example, which includes a privacy pixel group 20 (second pixel group 20a), the second pixel group 20a includes a first color sub-pixel 101, two second color sub-pixels 102 and a third color sub-pixel 103. Along the first direction X, these four sub-pixels are arranged in the order of first color sub-pixel 101, second color sub-pixel 102, third color sub-pixel 103 and second color sub-pixel 102.

[0023] In this sub-pixel, the first color sub-pixel emits the first color, the second color sub-pixel emits the second color, and the third color sub-pixel emits the third color. The first, second, and third colors are all different, and their color combinations can be any combination of colors that can be mixed to produce white, such as a combination of red, green, and blue. Following the pixel arrangement described above, refer to... Figure 2 In shared mode, the SPR (Sub-Pixel Rendering) algorithm can be used to allow two adjacent shared pixels P1 to share either the first color sub-pixel 101 or the third color sub-pixel 103, while each shared pixel P1 independently contains a second color sub-pixel 102. Similarly, refer to... Figure 3 In privacy mode, the SPR algorithm can be used to allow two adjacent privacy pixels P2 to share either the first color sub-pixel 101 or the third color sub-pixel 103, while each privacy pixel P2 independently contains a second color sub-pixel 102. In this way, the display effect can be guaranteed through software algorithms, while a larger number of pixels P can be achieved with a smaller number of sub-pixels in the hardware. The space saved by subtracting sub-pixels can be used to increase the aperture area of ​​the remaining sub-pixels, thereby improving the aperture ratio, enhancing the display effect, and extending the lifespan of the display panel.

[0024] In other embodiments, the SPR algorithm can also involve two adjacent shared pixels P1 sharing the first color sub-pixel 101 and the third color sub-pixel 103, and two adjacent privacy pixels P2 sharing the first color sub-pixel 101 and the third color sub-pixel 103. In summary, the pixel arrangement provided in this embodiment of the invention can use the SPR algorithm for display driving, reducing the number of sub-pixels and increasing the aperture ratio.

[0025] Optionally, one of the first color sub-pixel 101 and the third color sub-pixel 103 is a red sub-pixel, and the other is a blue sub-pixel; the second color sub-pixel 102 is a green sub-pixel. Since the human eye is more sensitive to green, by setting the second color sub-pixel 102 to a green sub-pixel, each pixel P can independently have a green sub-pixel, which helps to ensure the display effect.

[0026] Furthermore, Figure 1In the attached figures “10-1”, “10-2”, “10-3”, and “10-4”, the number after “10-” indicates the sequence number i of the shared pixel group 10. Similarly, in the attached figures “20-1”, “20-2”, “20-3”, and “20-4”, the number after “20-” indicates the sequence number j of the privacy pixel group 20 (the same applies below). Figure 1 In the entire display panel 100, along the second direction Y, shared pixel group 10 and privacy pixel group 20 are arranged alternately, and in the i-th shared pixel group 10-i and the j-th (j=i) privacy pixel group 20-j, sub-pixels of the same color overlap along the second direction Y.

[0027] Specifically, the number of shared pixel groups 10 in the first pixel unit 110 is greater than or equal to 1, and the number of privacy pixel groups 20 in the second pixel unit 120 is greater than or equal to 1. The number of shared pixel groups 10 in the first pixel unit 110 is equal to the number of privacy pixel groups 20 in the second pixel unit 120. Furthermore, regardless of how many shared pixel groups 10 the first pixel unit 110 includes, the shared pixel groups 10 and privacy pixel groups 20 are arranged alternately in the second direction Y. If the shared pixel groups 10 and privacy pixel groups 20 in the display panel 100 are sorted separately along the second direction Y, the sub-pixels of the same color in the shared pixel groups 10 and privacy pixel groups 20 with the same sequence number overlap along the second direction Y. This setting allows the shared sub-pixels and privacy sub-pixels to be evenly distributed in the display panel, ensuring that the display effects of both the shared mode 10 and the privacy mode 20 are taken into account.

[0028] For example, Figure 1 Taking the example of the first pixel unit 110 including a shared pixel group 10 (first pixel group 10a) and the second pixel unit 120 including a privacy pixel group 20 (second pixel group 20a), the first pixel group 10a and the second pixel group 20a are arranged alternately along the second direction Y. The sub-pixels in the first pixel group 10a and the second pixel group 20a have the same color arrangement in the first direction X, and the sub-pixels of the same color overlap along the second direction Y.

[0029] In summary, the technical solution of this invention optimizes pixel arrangement by setting the first pixel unit that emits light in shared mode to include at least one shared pixel group, and the second pixel unit that emits light in privacy mode to include at least one privacy pixel group. Along the second direction, the shared pixel group and the privacy pixel group are arranged alternately. Furthermore, in the i-th shared pixel group and the j-th (j=i) privacy pixel group, sub-pixels of the same color overlap along the second direction. For example, the shared pixel group in the first pixel unit includes at least the first pixel group, and the privacy pixel group in the second pixel unit includes at least the second pixel group. The sub-pixels in the first pixel group and the second pixel group are arranged sequentially in the first direction in the order of first color sub-pixel, second color sub-pixel, third color sub-pixel, and second color sub-pixel. In this way, adjacent pixels can share the first color sub-pixel and / or the third color sub-pixel, reducing the number of sub-pixels in the display panel, increasing the aperture ratio, increasing brightness, and optimizing the display effect. It can also make the privacy sub-pixels and shared sub-pixels evenly distributed in the display panel, ensuring that the display effect of both shared mode and privacy mode is taken into account.

[0030] Next, taking the example of the first pixel unit 110 including two or more shared pixel groups 10 and the second pixel unit 120 including two or more privacy pixel groups 20, we will further illustrate the pixel arrangement method.

[0031] For example, Figure 4 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 5 yes Figure 4 The diagram shown illustrates the display panel in shared mode. Figure 6 yes Figure 4 The diagram shown illustrates the display panel in privacy mode. (Refer to...) Figures 4-6 Optionally, the first pixel unit 110 includes at least two shared pixel groups 10 arranged along the second direction Y. Each shared pixel group 10 includes a first color sub-pixel 101, two second color sub-pixels 102, and a third color sub-pixel 103 arranged along the first direction X. The second color sub-pixels 102 in adjacent shared pixel groups 10 are staggered in the first direction X. The second pixel unit 120 includes at least two privacy pixel groups 20 arranged along the second direction Y. Each privacy pixel group 20 includes a first color sub-pixel 101, two second color sub-pixels 102, and a third color sub-pixel 103 arranged along the first direction X. The second color sub-pixels 102 in adjacent privacy pixel groups 20 are staggered in the first direction X.

[0032] Reference Figure 4 and Figure 5When the first pixel unit 110 includes two or more shared pixel groups 10, the shared pixel groups 10 in the first pixel unit 110 are arranged in the second direction Y. Each shared pixel group 10 includes a first color sub-pixel 101, two second color sub-pixels 102 and a third color sub-pixel 103 arranged in the first direction X, and the second color sub-pixels 102 in two adjacent shared pixel groups 10 are staggered in the first direction X.

[0033] Specifically, in each shared pixel group 10, the number of sub-pixels of each color is the same, but their arrangement order in the first direction X is different, so that in two adjacent shared pixel groups 10 in the second direction Y, the second color sub-pixels 102 are misaligned in the first direction X. (Refer to...) Figure 5 For two adjacent shared pixel groups 10 in the second direction Y, the second color sub-pixel 102 in one shared pixel group 10 and the second color sub-pixel 102 in the other shared pixel group 10 do not overlap in the second direction Y (any virtual straight line extending along the second direction Y will not pass through two second color sub-pixels 102 in the two adjacent shared pixel groups 10 at the same time). The center line L1 connecting the two adjacent second color sub-pixels 102 in the two adjacent shared pixel groups 10 in the second direction Y intersects both the first direction X and the second direction Y. Multiple center lines L1 form a triangular wave shape.

[0034] Reference Figure 5 Alternatively, along the second direction Y, a second color sub-pixel 102 in a shared pixel group 10 overlaps with a first color sub-pixel 101 or a third color sub-pixel 103 in another adjacent shared pixel group 10 in the second direction Y. In this way, the coordinate ranges of adjacent shared pixel groups 10 in the first direction X are basically the same, which can reduce space waste and ensure space utilization.

[0035] Reference Figure 4 and Figure 6 When the second pixel unit 120 includes two or more privacy pixel groups 20, the privacy pixel groups 20 in the second pixel unit 120 are arranged in the second direction Y. Each privacy pixel group 20 includes a first color sub-pixel 101, two second color sub-pixels 102 and a third color sub-pixel 103 arranged in the first direction X, and the second color sub-pixels 102 in two adjacent privacy pixel groups 20 are staggered in the first direction X.

[0036] Specifically, in each privacy pixel group 20, the number of sub-pixels of each color is the same, but their arrangement order in the first direction X is different, so that in two adjacent privacy pixel groups 20 in the second direction Y, the second color sub-pixels 102 are misaligned in the first direction X. (Refer to...) Figure 6For two adjacent privacy pixel groups 20 in the second direction Y, the second color sub-pixel 102 in one privacy pixel group 20 and the second color sub-pixel 102 in the other privacy pixel group 20 do not overlap in the second direction Y (any virtual straight line extending along the second direction Y will not pass through the two second color sub-pixels 102 in the two adjacent privacy pixel groups 20 at the same time). The center line L2 of the two adjacent second color sub-pixels 102 in the two adjacent privacy pixel groups 20 along the second direction Y intersects both the first direction X and the second direction Y. Multiple center lines L2 form a triangular wave shape.

[0037] Reference Figure 6 Alternatively, along the second direction Y, the second color sub-pixel 102 in one privacy pixel group 20 overlaps with the first color sub-pixel 101 or the third color sub-pixel 103 in another adjacent privacy pixel group 20 in the second direction Y. In this way, the coordinate range of the adjacent privacy pixel groups 20 in the first direction X is basically the same, which can reduce space waste and ensure space utilization.

[0038] Reference Figure 4 When the first pixel unit 110 includes two or more shared pixel groups 10 and the second pixel unit 120 includes two or more privacy pixel groups 20, in the entire display panel 100, along the second direction Y, the shared pixel groups 10 and privacy pixel groups 20 are alternately arranged. At this time, the area where the first pixel unit 110 is located and the area where the second pixel unit 120 is located overlap each other in the thickness direction of the display panel (the shared pixel groups 10 and privacy pixel groups 20 do not overlap).

[0039] Reference Figure 4 The arrangement of three different colored sub-pixels in the first direction X effectively improves the color shift problem at the edge of the display panel in the second direction Y. Furthermore, by setting both the first pixel unit 110 and the second pixel unit 120 to include two or more pixel groups, and by setting the second-colored sub-pixels 102 in two adjacent shared pixel groups (spy pixel groups) to be staggered in the first direction X, the display panel can arrange at least two colored sub-pixels in the second direction Y, which helps to improve the color shift problem at the edge of the display panel in the first direction X.

[0040] As one possible implementation method, refer to Figures 4-6Optionally, in addition to the first pixel group 10a, the shared pixel group 10 in the first pixel unit 110 also includes a third pixel group 10b; in the third pixel group 10b, the second color sub-pixel 102, the first color sub-pixel 101, the second color sub-pixel 102 and the third color sub-pixel 103 are arranged sequentially along the first direction X; in addition to the second pixel group 20a, the privacy pixel group 20 in the second pixel unit 120 also includes a fourth pixel group 20b; in the fourth pixel group 20b, the second color sub-pixel 102, the first color sub-pixel 101, the second color sub-pixel 102 and the third color sub-pixel 103 are arranged sequentially along the first direction X; the first pixel group 10a, the second pixel group 20a, the third pixel group 10b and the fourth pixel group 20b are arranged sequentially along the second direction Y.

[0041] Reference Figure 5 The first pixel group 10a and the third pixel group 10b, two shared pixel groups arranged along the second direction Y, serve as a minimum repeating unit (first pixel unit 110) in the shared mode, and are periodically arrayed in the first direction X and the second direction Y. In the third pixel group 10b, four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, first color sub-pixel 101, second color sub-pixel 102, and third color sub-pixel 103. The second color sub-pixel 102 in the first pixel group 10a and the second color sub-pixel 102 in the third pixel group 10b do not overlap in the second direction Y. In the first pixel group 10a, one second color sub-pixel 102 overlaps with the first color sub-pixel 101 in the third pixel group 10b, and another second color sub-pixel 102 overlaps with the third color sub-pixel 103 in the third pixel group 10b, and vice versa.

[0042] Similarly, refer to Figure 6 The second pixel group 20a and the fourth pixel group 20b, arranged along the second direction Y, serve as a minimum repeating unit (second pixel unit 120) in the privacy mode, and are periodically arrayed in the first direction X and the second direction Y. In the fourth pixel group 20b, four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, first color sub-pixel 101, second color sub-pixel 102, and third color sub-pixel 103. The second color sub-pixel 102 in the second pixel group 20a and the second color sub-pixel 102 in the fourth pixel group 20b do not overlap in the second direction Y. In the second pixel group 20a, one second color sub-pixel 102 overlaps with the first color sub-pixel 101 in the fourth pixel group 20b in the second direction Y, and another second color sub-pixel 102 overlaps with the third color sub-pixel 103 in the fourth pixel group 20b, and vice versa.

[0043] Reference Figure 4 In the entire display panel 100, the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, and the fourth pixel group 20b are arranged sequentially along the second direction Y. That is, in the second direction Y, the pixel groups are arranged in the order of first pixel group 10a, second pixel group 20a, third pixel group 10b, and fourth pixel group 20b, with one arrangement cycle from the first pixel group 10a, second pixel group 20a, third pixel group 10b to the fourth pixel group 20b. In this scheme, the display panel 100 arranges two colors of sub-pixels (first color sub-pixel 101 and second color sub-pixel 102, or third color sub-pixel 103 and second color sub-pixel 102) in the second direction Y, thereby improving the color shift problem at the edges of the display panel in the first direction X.

Figures 7-9 Optionally, in addition to the first pixel group 10a, the shared pixel group 10 in the first pixel unit 110 also includes a seventh pixel group 10d; in the seventh pixel group 10d, the second color sub-pixel 102, the third color sub-pixel 103, the second color sub-pixel 102 and the first color sub-pixel 101 are arranged sequentially along the first direction X; in addition to the second pixel group 20a, the privacy pixel group 20 in the second pixel unit 120 also includes an eighth pixel group 20d; in the eighth pixel group 20d, the second color sub-pixel 102, the third color sub-pixel 103, the second color sub-pixel 102 and the first color sub-pixel 101 are arranged sequentially along the first direction X; the first pixel group 10a, the second pixel group 20a, the seventh pixel group 10d and the eighth pixel group 20d are arranged sequentially along the second direction Y.

[0045] Reference Figure 8The first pixel group 10a and the seventh pixel group 10d, two shared pixel groups 10 arranged along the second direction Y, serve as a minimum repeating unit (first pixel unit 110) in the shared mode, and are periodically arrayed in the first direction X and the second direction Y. In the seventh pixel group 10d, four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, third color sub-pixel 103, second color sub-pixel 102, and first color sub-pixel 101. The second color sub-pixel 102 in the first pixel group 10a does not overlap with the second color sub-pixel 102 in the seventh pixel group 10d in the second direction Y. In the first pixel group 10a, one second color sub-pixel 102 overlaps with the first color sub-pixel 101 in the seventh pixel group 10d in the second direction Y, and another second color sub-pixel 102 overlaps with the third color sub-pixel 103 in the seventh pixel group 10d, and vice versa.

[0046] Similarly, refer to Figure 9 The second pixel group 20a and the eighth pixel group 20d, arranged along the second direction Y, serve as a minimum repeating unit (second pixel unit 120) in the privacy mode, and are periodically arrayed in the first direction X and the second direction Y. In the eighth pixel group 20d, four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, third color sub-pixel 103, second color sub-pixel 102, and first color sub-pixel 101. The second color sub-pixel 102 in the second pixel group 20a does not overlap with the second color sub-pixel 102 in the eighth pixel group 20d in the second direction Y. In the second pixel group 20a, one second color sub-pixel 102 overlaps with the first color sub-pixel 101 in the eighth pixel group 20d in the second direction Y, and another second color sub-pixel 102 overlaps with the third color sub-pixel 103 in the eighth pixel group 20d, and vice versa.

[0047] Reference Figure 7 In the entire display panel 100, the first pixel group 10a, the second pixel group 20a, the seventh pixel group 10d, and the eighth pixel group 20d are arranged sequentially along the second direction Y. That is, in the second direction Y, the pixel groups are arranged in the order of the first pixel group 10a, the second pixel group 20a, the seventh pixel group 10d, and the eighth pixel group 20d, with one arrangement cycle from the first pixel group 10a, the second pixel group 20a, the seventh pixel group 10d to the eighth pixel group 20d. In this scheme, the display panel 100 also arranges two colors of sub-pixels (first color sub-pixel 101 and second color sub-pixel 102, or third color sub-pixel 103 and second color sub-pixel 102) in the second direction Y, thereby improving the color shift problem at the edge of the display panel in the first direction X.

[0048] Figures 4-6 and Figures 7-9 Both schemes involve the first pixel unit 110 comprising two shared pixel groups 10, the difference being the arrangement order of the sub-pixels in the second shared pixel group. (Refer to...) Figures 4-6 In shared mode or privacy mode, adjacent pixels P can share either the first color sub-pixel 101 or the third color sub-pixel 103 in the first direction X. (See reference...) Figures 7-9 In shared mode or privacy mode, adjacent pixels P can share the first color sub-pixel 101 and the third color sub-pixel 103 in the first direction X and the second direction Y. For example, refer to Figure 8 In a first pixel unit 110, two adjacent shared pixel groups 10, two adjacent second color sub-pixels (such as 102a and 102b) share an adjacent first color sub-pixel 101a and a third color sub-pixel 103a, forming two pixels P. It should be noted that for... Figures 7-9 In other embodiments, the pixel arrangement shown may also involve adjacent pixels P sharing the first color sub-pixel 101 or the third color sub-pixel 103 in the first direction X. This embodiment of the invention does not limit this.

Figures 10-12Optionally, in addition to the first pixel group 10a, the shared pixel group 10 in the first pixel unit 110 also includes a third pixel group 10b, a fifth pixel group 10c, and a seventh pixel group 10d; in the third pixel group 10b, the second color sub-pixel 102, the first color sub-pixel 101, the second color sub-pixel 102, and the third color sub-pixel 103 are arranged sequentially along the first direction X; in the fifth pixel group 10c, the third color sub-pixel 103, the second color sub-pixel 102, the first color sub-pixel 101, and the second color sub-pixel 102 are arranged sequentially along the first direction X; in the seventh pixel group 10d, the second color sub-pixel 102, the third color sub-pixel 103, the second color sub-pixel 102, and the first color sub-pixel 101 are arranged sequentially along the first direction X; in addition to the second pixel group 20a, the privacy pixel group 20 in the second pixel unit 120 also includes a fourth pixel group 2 0b, sixth pixel group 20c and eighth pixel group 20d; in fourth pixel group 20b, second color sub-pixel 102, first color sub-pixel 101, second color sub-pixel 102 and third color sub-pixel 103 are arranged sequentially along the first direction X; in sixth pixel group 20c, third color sub-pixel 103, second color sub-pixel 102, first color sub-pixel 101 and second color sub-pixel 102 are arranged sequentially along the first direction X; in eighth pixel group 20d, second color sub-pixel 102, third color sub-pixel 103, second color sub-pixel 102 and first color sub-pixel 101 are arranged sequentially along the first direction X; first pixel group 10a, second pixel group 20a, third pixel group 10b, fourth pixel group 20b, fifth pixel group 10c, sixth pixel group 20c, seventh pixel group 10d and eighth pixel group 20d are arranged sequentially along the second direction Y.

[0050] Reference Figure 11Four shared pixel groups 10—first pixel group 10a, third pixel group 10b, fifth pixel group 10c, and seventh pixel group 10d—are arranged sequentially along the second direction Y, serving as first pixel units 110, and are periodically arrayed in the first direction X and the second direction Y. The sub-pixels in these four shared pixel groups 10 are arranged in different orders, and the second color sub-pixels 102 in any two adjacent shared pixel groups 10 along the second direction Y do not overlap in the second direction Y. Specifically, in the first pixel group 10a, the four sub-pixels are arranged sequentially in the first direction X in the order of first color sub-pixel 101, second color sub-pixel 102, third color sub-pixel 103, and second color sub-pixel 102; in the third pixel group 10b, the four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, first color sub-pixel 101, second color sub-pixel 102, and third color sub-pixel 103; in the fifth pixel group 10c, the four sub-pixels are arranged sequentially in the first direction X in the order of third color sub-pixel 103, second color sub-pixel 102, first color sub-pixel 101, and second color sub-pixel 102; and in the seventh pixel group 10d, the four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, third color sub-pixel 103, second color sub-pixel 102, and first color sub-pixel 101.

[0051] Reference Figure 12 The four privacy pixel groups 20—second pixel group 20a, fourth pixel group 20b, sixth pixel group 20c, and eighth pixel group 20d—are arranged sequentially along the second direction Y, serving as second pixel units 120, and are periodically arrayed in the first direction X and the second direction Y. The sub-pixels in these four privacy pixel groups 20 are arranged in different orders, and the second color sub-pixels 102 in any two adjacent privacy pixel groups 20 along the second direction Y do not overlap in the second direction Y. Specifically, in the second pixel group 20a, the four sub-pixels are arranged sequentially in the first direction X in the order of first color sub-pixel 101, second color sub-pixel 102, third color sub-pixel 103, and second color sub-pixel 102; in the fourth pixel group 20b, the four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, first color sub-pixel 101, second color sub-pixel 102, and third color sub-pixel 103; in the sixth pixel group 20c, the four sub-pixels are arranged sequentially in the first direction X in the order of third color sub-pixel 103, second color sub-pixel 102, first color sub-pixel 101, and second color sub-pixel 102; and in the eighth pixel group 20d, the four sub-pixels are arranged sequentially in the first direction X in the order of second color sub-pixel 102, third color sub-pixel 103, second color sub-pixel 102, and first color sub-pixel 101.

[0052] Reference Figure 10In the entire display panel 100, the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, the fourth pixel group 20b, the fifth pixel group 10c, the sixth pixel group 20c, the seventh pixel group 10d, and the eighth pixel group 20d are arranged sequentially along the second direction Y. That is to say, in the second direction Y, each pixel group is arranged in the order of the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, the fourth pixel group 20b, the fifth pixel group 10c, the sixth pixel group 20c, the seventh pixel group 10d, and the eighth pixel group 20d, forming one arrangement cycle from the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, the fourth pixel group 20b, the fifth pixel group 10c, the sixth pixel group 20c, the seventh pixel group 10d, to the eighth pixel group 20d. The display panel 100 has three colors of sub-pixels (first color sub-pixel 101, second color sub-pixel 102 and third color sub-pixel 103) arranged in the second direction Y, which can further improve the color shift problem at the edge of the display panel in the first direction X.

[0053] As another feasible implementation method Figure 13 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 14 yes Figure 13 The diagram shown illustrates the display panel in shared mode. Figure 15 yes Figure 13 The diagram shown illustrates the display panel in privacy mode. (Refer to...) Figures 13-15 When the first pixel unit 110 includes a first pixel group 10a, a third pixel group 10b, a fifth pixel group 10c, and a seventh pixel group 10d, and the second pixel unit 120 includes a second pixel group 20a, a fourth pixel group 20b, a sixth pixel group 20c, and an eighth pixel group 20d, optionally, the first pixel group 10a, the second pixel group 20a, the seventh pixel group 10d, the eighth pixel group 20d, the fifth pixel group 10c, the sixth pixel group 20c, the third pixel group 10b, and the fourth pixel group 20b are arranged sequentially along the second direction Y.

[0054] In this embodiment, the arrangement order of sub-pixels in each pixel group along the first direction X is the same as... Figure 10 The illustrated embodiments use the same arrangement, differing only in the order in which the pixel groups are arranged in the second direction Y. This scheme also allows the display panel to have three colors of sub-pixels arranged in the second direction Y, thereby further improving the color shift problem at the edges of the display panel in the first direction X.

[0055] Regarding pixel rendering methods Figures 10-12 In the scheme shown, in the sharing mode or the privacy mode, adjacent pixels P can be shared by the first color sub-pixel 101 or the third color sub-pixel 103 in the first direction X. Figures 13-15 In the scheme shown, in the sharing mode or the privacy mode, adjacent pixels P can share the first color sub-pixel 101 and the third color sub-pixel 103 in the first direction X and the second direction Y, or adjacent pixels P can share the first color sub-pixel 101 or the third color sub-pixel 103 in the first direction X.

[0056] Figure 16 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 17 yes Figure 16 The diagram shown illustrates the display panel in shared mode. Figure 18 yes Figure 16 The diagram shown illustrates the display panel in privacy mode. (Refer to...) Figures 16-18When the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, the fourth pixel group 20b, the fifth pixel group 10c, the sixth pixel group 20c, the seventh pixel group 10d, and the eighth pixel group 20d are arranged sequentially along the second direction Y, optionally, the display panel 100 further includes a first compensation sub-pixel 1001, a second compensation sub-pixel 1002, a third compensation sub-pixel 1003, a fourth compensation sub-pixel 1004, a fifth compensation sub-pixel 1005, a sixth compensation sub-pixel 1006, a seventh compensation sub-pixel 1007, and an eighth compensation sub-pixel 1008; the first compensation... Compensation sub-pixels 1001, 1002, 1007, and 1008 all have the same emission color as the first color sub-pixel 101; compensation sub-pixels 1003, 1004, 1005, and 1006 all have the same emission color as the third color sub-pixel 103; along the first direction X: the first compensation sub-pixel 1001 is located on one side of all first pixel groups 10a and is adjacent to the outermost second color sub-pixel 102 in all first pixel groups 10a; the second compensation sub-pixel 1001... Compensation sub-pixel 1002 is located on one side of all second pixel groups 20a and is adjacent to the outermost second color sub-pixel 102 in all second pixel groups 20a; the third compensation sub-pixel 1003 is located on one side of all third pixel groups 10b and is adjacent to the outermost second color sub-pixel 102 in all third pixel groups 10b; the fourth compensation sub-pixel 1004 is located on one side of all fourth pixel groups 20b and is adjacent to the outermost second color sub-pixel 102 in all fourth pixel groups 20b; the fifth compensation sub-pixel 1005 is located on one side of all fifth pixel groups 10c and is adjacent to the outermost second color sub-pixel 102 in all fifth pixel groups 10a. The fifth pixel group 10c is adjacent to the outermost second color sub-pixel 102; the sixth compensation sub-pixel 1006 is located on one side of all the sixth pixel groups 20c and is adjacent to the outermost second color sub-pixel 102 of all the sixth pixel groups 20c; the seventh compensation sub-pixel 1007 is located on one side of all the seventh pixel groups 10d and is adjacent to the outermost second color sub-pixel 102 of all the seventh pixel groups 10d; the eighth compensation sub-pixel 1008 is located on one side of all the eighth pixel groups 20d and is adjacent to the outermost second color sub-pixel 102 of all the eighth pixel groups 20d.

[0057] Specifically, refer to Figure 17In the sharing mode, when adjacent shared pixels P1 share a first color sub-pixel 101 or a third color sub-pixel 103 in the first direction X, a compensation sub-pixel is set outside the outermost second color sub-pixel 102, and the color of the compensation sub-pixel is consistent with the color of the outermost sub-pixel on the other side. This allows the outermost second color sub-pixel 102, the compensation sub-pixel, and the shared sub-pixel on the side of the second color sub-pixel 102 away from the compensation sub-pixel to form a shared pixel P1 (such as shared pixels P1a and shared pixels P1b). For example, refer to... Figure 17 In the first direction X, one edge of all first pixel groups 10a is a first color sub-pixel 101, and the other edge is a second color sub-pixel 102. By setting a first compensation sub-pixel 1001 with the same color as the first color sub-pixel 101 outside the second color sub-pixel 102 at this edge, the first compensation sub-pixel 1001, the outermost second color sub-pixel 102, and the third color sub-pixel 103 adjacent to the outermost second color sub-pixel 102 can form a shared pixel P1a. Similarly, one edge of all third pixel groups 10b is a third color sub-pixel 103, and the other edge is a second color sub-pixel 102. By setting a third compensation sub-pixel 1003 with the same color as the third color sub-pixel 103 outside the second color sub-pixel 102 at this edge, the third compensation sub-pixel 1003, the outermost second color sub-pixel 102, and the first color sub-pixel 101 adjacent to the outermost second color sub-pixel 102 can form a shared pixel P1b. This allows for further optimization of the display effect at the edge of the display panel in the first direction X.

[0058] Similarly, refer to Figure 18 In privacy mode, when adjacent privacy pixels P2 share a first color sub-pixel 101 or a third color sub-pixel 103 in the first direction X, a compensation sub-pixel is set outside the outermost second color sub-pixel 102, and the color of this compensation sub-pixel is set to be consistent with the color of the outermost sub-pixel on the other side. This allows the outermost second color sub-pixel 102, the compensation sub-pixel, and the privacy sub-pixel on the side of the second color sub-pixel 102 away from the compensation sub-pixel to form a privacy pixel P2 (such as privacy pixels P2a and privacy pixels P2b). For example, refer to... Figure 18In the first direction X, one edge of all second pixel groups 20a is a first color sub-pixel 101, and the other edge is a second color sub-pixel 102. By setting a second compensation sub-pixel 1002 with the same color as the first color sub-pixel 101 outside the second color sub-pixel 102 at this edge, the second compensation sub-pixel 1002, the outermost second color sub-pixel 102, and the third color sub-pixel 103 adjacent to the outermost second color sub-pixel 102 can form a privacy pixel P2a. One edge of all fourth pixel groups 20b is a third color sub-pixel 103, and the other edge is a second color sub-pixel 102. By setting a fourth compensation sub-pixel 1004 with the same color as the third color sub-pixel 103 outside the second color sub-pixel 102 at this edge, the fourth compensation sub-pixel 1004, the outermost second color sub-pixel 102, and the first color sub-pixel 101 adjacent to the outermost second color sub-pixel 102 can form a privacy pixel P2b. This allows for further optimization of the display effect at the edge of the display panel in the first direction X.

[0059] It should be noted that when the SPR algorithm uses adjacent pixels to share the first color sub-pixel 101 or the third color sub-pixel 103 in the first direction X for display driving, the above scheme of setting compensation sub-pixels is applicable to all pixel arrangement methods, and will not be explained in detail here.

[0060] Figure 19 yes Figure 13 Enlarged schematic diagram of region Q1 in the middle area. Figure 20 It is along Figure 19 A cross-sectional view of the display panel, captured by UU'. Figure 21 It is along Figure 19 The cross-sectional structural diagram of the display panel, taken from section VV', is shown below. Figure 13 , Figures 19-21Optionally, in the first pixel unit 110 (shared pixel group 10), the first color sub-pixel 101 has a first light-emitting area S1, the second color sub-pixel 102 has a second light-emitting area S2, and the third color sub-pixel 103 has a third light-emitting area S3; in the second pixel unit 120, the first color sub-pixel 101 has a fourth light-emitting area S4, the second color sub-pixel 102 has a fifth light-emitting area S5, and the third color sub-pixel 103 has a sixth light-emitting area S6; along the first direction X, the first light-emitting area S1 includes a first boundary E1 and a second boundary E2, the second light-emitting area S2 includes a third boundary E3 and a fourth boundary E4, and the third light-emitting area S3 includes a fifth boundary E5 and a sixth boundary E6; the fourth light-emitting area S4 is located between the extension lines of the first boundary E1 and the second boundary E2 in the second direction Y, the fifth light-emitting area S5 is located between the extension lines of the third boundary E3 and the fourth boundary E4 in the second direction Y, and the sixth light-emitting area S6 is located between the extension lines of the fifth boundary E5 and the sixth boundary E6 in the second direction Y.

[0061] Specifically, refer to Figure 20 The display panel 100 includes a substrate 30, an array layer 40, a pixel defining layer 50, and a light-emitting element 60. A pixel circuit 410 is disposed in the array layer 40, and the pixel circuit 410 is electrically connected to the light-emitting element 60 to drive the light-emitting element 60 to emit light. The pixel circuit 410 is typically composed of a thin-film transistor and a storage capacitor. Figure 20 Only one thin-film transistor in the pixel circuit is shown; the specific circuit structure can be designed independently. The pixel defining layer 50 has a pixel opening 501. The light-emitting element 60 includes an anode 601, a light-emitting functional layer 602, and a cathode 603. The pixel opening 501 exposes the anode 601, at least a portion of the light-emitting functional layer 602 is located within the pixel opening 501, and the cathode 603 covers the light-emitting functional layer 602. The pixel opening 501 can define the shape, size, and arrangement of the light-emitting area of ​​the light-emitting element 60. A sub-pixel includes a light-emitting element and a pixel circuit. The light-emitting area of ​​each sub-pixel specifically refers to the area defined by the pixel opening 501 where the corresponding light-emitting element 60 is located.

[0062] Furthermore, referring to Figure 19 It should be noted that the fourth light-emitting area S4 is located between the extension lines of the first boundary E1 and the second boundary E2 in the second direction Y, the fifth light-emitting area S5 is located between the extension lines of the third boundary E3 and the fourth boundary E4 in the second direction Y, and the sixth light-emitting area S6 is located between the extension lines of the fifth boundary E5 and the sixth boundary E6 in the second direction Y. This applies to the corresponding color sub-pixels in any group of shared pixel groups 10 and privacy pixel groups 20 with the same serial number, and is applicable to any pixel arrangement scheme provided in the above embodiments.

[0063] Specifically, for any set of shared pixel group 10 and privacy pixel group 20 with the same serial number, the light emission colors of two sub-pixels that overlap along the second direction Y in shared pixel group 10 and privacy pixel group 20 are the same and correspond to each other. The light emission area of ​​each color sub-pixel in privacy pixel group 20 is located within the boundary range of the corresponding color sub-pixel in shared pixel group 10 in the first direction X.

[0064] The material of the light-emitting functional layer is usually formed by vapor deposition. Specifically, different masks are used when vapor-depositing different colored light-emitting materials. By using masks with different openings in sequence, the light-emitting materials of different colors are vapor-deposited into the corresponding pixel openings. For shared pixel group 10 and privacy pixel group 20 with the same serial number, this embodiment sets the light-emitting area of ​​each color sub-pixel in privacy pixel group 20 to be located within the boundary range of the corresponding color sub-pixel in shared pixel group 10 in the first direction X. In this way, the corresponding shared sub-pixels and privacy sub-pixels can share a mask opening for the deposition of light-emitting materials. For example, the first light-emitting area S1 and the fourth light-emitting area S4 can be deposited with the first color light-emitting material through the same mask opening; the second light-emitting area S2 and the fifth light-emitting area S5, which overlap along the second direction Y, can be deposited with the second color light-emitting material through the same mask opening; and the third light-emitting area S3 and the sixth light-emitting area S6 can be deposited with the third color light-emitting material through the same mask opening. This helps to reduce the distance between shared pixel group 10 and privacy pixel group 20 with the same serial number in the second direction Y, improves space utilization, reduces the difficulty of mask manufacturing, improves yield, and reduces costs and increases efficiency.

[0065] Reference Figure 19 and Figure 20 Optionally, the display panel 100 further includes a light-shielding structure 70, which is located on the side of the film layer where the second pixel unit 120 is located away from the substrate 30; any one of the light-emitting areas in the second pixel unit 120 has a first orthographic projection on the substrate 30, and the light-shielding structure 70 has a second orthographic projection on the substrate 30, with the second orthographic projection and the first orthographic projection alternating along the first direction X; the light-emitting areas include a fourth light-emitting area S4, a fifth light-emitting area S5, and a sixth light-emitting area S6.

[0066] Specifically, the fourth light-emitting area S4, the fifth light-emitting area S5, and the sixth light-emitting area S6 are arranged along the first direction X. Along the first direction X, light-shielding structures 70 are provided on both sides of the light-emitting area (fourth light-emitting area S4, fifth light-emitting area S5, or sixth light-emitting area S6) of any privacy-protecting sub-pixel. A light-shielding structure 70 is located between any two adjacent light-emitting areas S4, S5, and S6. Further, the light-shielding structure 70 is specifically located on the side of the film layer where the light-emitting element 60 is located, away from the substrate 30, and the light-shielding structure 70 does not overlap with the pixel opening 501. (Comparison) Figure 19 and Figure 20 By setting the light-blocking structure 70 for the corresponding privacy sub-pixel, the viewing angle (β) in privacy mode can be smaller than the viewing angle (α) in sharing mode, thus achieving privacy function.

[0067] It should be noted that the accompanying drawings of this embodiment are only used as an example to illustrate that each sub-pixel in the privacy pixel group 20 has a light-shielding structure 70 on both sides of the opposite side in the first direction X. In other embodiments, each sub-pixel in the privacy pixel group 20 may also have a light-shielding structure on both sides of the opposite side in the second direction Y to achieve an all-round privacy effect.

[0068] Continue to refer to Figure 19 Optionally, in the second pixel unit 120 (spy pixel group 20), the first color sub-pixel 101 has a fourth light-emitting area S4, the second color sub-pixel 102 has a fifth light-emitting area S5, and the third color sub-pixel 103 has a sixth light-emitting area S6; along the first direction X, the length X4 of the fourth light-emitting area S4 is less than or equal to the length X1 of the first light-emitting area S1, the length X5 of the fifth light-emitting area S5 is less than or equal to the length X2 of the second light-emitting area S2, and the length X6 of the sixth light-emitting area S6 is less than or equal to the length X3 of the third light-emitting area S3.

[0069] For example, Figure 19 Taking the example where the length x4 of the fourth light-emitting area S4 is less than the length x1 of the first light-emitting area S1, the length x5 of the fifth light-emitting area S5 is less than the length x2 of the second light-emitting area S2, and the length x6 of the sixth light-emitting area S6 is less than the length x3 of the third light-emitting area S3, this arrangement helps to reduce the manufacturing precision requirements of the light-shielding structure 70, ensuring a certain distance between the light-shielding structure 70 and the pixel opening 501, thus avoiding excessive light shading and affecting the brightness of the front light output. Of course, in other embodiments, the length x4 of the fourth light-emitting area S4 can also be set to be equal to the length x1 of the first light-emitting area S1, the length x5 of the fifth light-emitting area S5 to be equal to the length x2 of the second light-emitting area S2, and the length x6 of the sixth light-emitting area S6 to be equal to the length x3 of the third light-emitting area S3. Under the condition that the process meets the standards, this arrangement helps to improve the privacy protection effect.

[0070] Furthermore, continue to refer to Figure 19Optionally, along the second direction Y, the center of the fourth light-emitting area S4 and the center of the first light-emitting area S1 are both located on the first virtual line K1, the center of the fifth light-emitting area S5 and the center of the second light-emitting area S2 are both located on the second virtual line K2, and the center of the sixth light-emitting area S6 and the center of the third light-emitting area S3 are both located on the third virtual line K3; the first virtual line K1, the second virtual line K2, and the third virtual line K3 are all parallel to the second direction Y. This configuration helps avoid image displacement or ghosting when switching between anti-peeping mode and sharing mode; when the second pixel unit 120 and the first pixel unit 110 are jointly lit to execute the sharing mode, it helps ensure the uniformity of in-plane brightness and guarantee the display effect; in addition, it also facilitates the regular arrangement of the light-shielding structure 70, reduces process difficulty, and improves process yield.

[0071] Figure 22 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 23 yes Figure 22 An enlarged schematic diagram of region Q2 in the middle area, see reference. Figure 22 and Figure 23 Optionally, in the second pixel unit 120, along the first direction X, the first color sub-pixel 101 has at least two fourth light-emitting areas S4, the second color sub-pixel 102 has one fifth light-emitting area S5, and the third color sub-pixel 103 has at least two sixth light-emitting areas S6; along the first direction X, the length X4 of the fourth light-emitting area S4 is less than the length X1 of the first light-emitting area S1, the length X5 of the fifth light-emitting area S5 is less than the length X2 of the second light-emitting area S2, and the length X6 of the sixth light-emitting area S6 is less than the length X3 of the third light-emitting area S3.

[0072] Specifically, in comparison Figure 23 and Figure 19In this embodiment, the first color sub-pixel 101 and the third color sub-pixel 103 in the second pixel unit 120 are further divided, dividing a large fourth light-emitting area S4 into two or more smaller fourth light-emitting areas S4, and dividing a large sixth light-emitting area S6 into two or more smaller sixth light-emitting areas S6. After the division, all the fourth light-emitting areas S4 corresponding to the first color sub-pixel 101 in the privacy pixel group 20 overlap with the first light-emitting area S1 corresponding to the first color sub-pixel 101 in the shared pixel group 10 along the second direction Y (for example, all are located within the boundary range of the first light-emitting area S1 in the first direction X). All the sixth light-emitting areas S6 corresponding to the third color sub-pixel 103 in the privacy pixel group 20 overlap with the third light-emitting area S3 corresponding to the third color sub-pixel 103 in the shared pixel group 10 along the second direction Y (for example, all are located within the boundary range of the third light-emitting area S3 in the first direction X). Moreover, a light-shielding structure 70 is provided between adjacent fourth light-emitting areas S4 after the division, and a light-shielding structure 70 is provided between adjacent sixth light-emitting areas S6 after the division. This setting helps to further reduce the light emission angle of the privacy sub-pixels and optimize the privacy protection effect.

[0073] It should be noted that, Figure 22 Taking the arrangement of the first pixel group 10a, the second pixel group 20a, the third pixel group 10b, the fourth pixel group 20b, the fifth pixel group 10c, the sixth pixel group 20c, the seventh pixel group 10d, and the eighth pixel group 20d along the second direction Y as an example, this illustrates the design of dividing the first color sub-pixel 101 and the third color sub-pixel 103 in the second pixel unit 120. The pixel arrangement schemes provided in other embodiments can also be designed in this way, and will not be illustrated one by one here.

[0074] Furthermore, Figure 24 It is along Figure 23 A cross-sectional structural diagram of a display panel, taken from the image below (DD'). Figure 23 and Figure 24 Optionally, in the second pixel unit 120: the first color sub-pixel 101 includes a first light-emitting element 61 and a first pixel circuit 411, the first light-emitting element 61 and the fourth light-emitting area S4 are in one-to-one correspondence, and all the first light-emitting elements 61 are connected to the same first pixel circuit 411; the third color sub-pixel 103 includes a third light-emitting element 63 and a third pixel circuit 413, the third light-emitting element 63 and the sixth light-emitting area S6 are in one-to-one correspondence, and all the third light-emitting elements 63 are connected to the same third pixel circuit 413.

[0075] As described above, any light-emitting area refers to the region defined by the corresponding pixel opening 501. One pixel opening 501 can define one light-emitting element 60. Therefore, there is a one-to-one correspondence between the light-emitting areas and the light-emitting elements 60. Specifically, in this embodiment, the first color sub-pixel 101 in the second pixel unit 120 includes at least two fourth light-emitting areas S4, and the third color sub-pixel 103 in the second pixel unit 120 includes at least two sixth light-emitting areas S6. Correspondingly, the first color sub-pixel 101 includes at least two first light-emitting elements 61, and the fourth light-emitting areas S4 correspond one-to-one with the first light-emitting elements 61. The third color sub-pixel 103 includes at least two third light-emitting elements 63, and the sixth light-emitting areas S6 correspond one-to-one with the third light-emitting elements 63.

[0076] Furthermore, in this embodiment, all the first light-emitting elements 61 corresponding to a first color sub-pixel 101 in the second pixel unit 120 are connected to the same first pixel circuit 411 and can be lit up simultaneously. All the third light-emitting elements 63 corresponding to a third color sub-pixel 103 are connected to the same third pixel circuit 413 and can be lit up simultaneously. At this time, the above-mentioned SPR algorithm can still be used to control the display driver in the privacy mode.

[0077] Reference Figure 23 and Figure 24 Optionally, all first light-emitting elements 61 corresponding to a first color sub-pixel 101 in the second pixel unit 120 share a common anode 601, and all third light-emitting elements 63 corresponding to a third color sub-pixel 103 in the second pixel unit 120 share a common anode 601. In this way, all first light-emitting elements 61 can be connected to the same first pixel circuit 411, and all third light-emitting elements 63 can be connected to the same third pixel circuit 413.

[0078] It should be noted that, Figure 23 Taking the example of the first color sub-pixel 101 in the second pixel unit 120 including two fourth light-emitting areas S4 and the third color sub-pixel 103 including two sixth light-emitting areas S6, in the case that all first light-emitting elements 61 are connected to the same first pixel circuit 411 and all third light-emitting elements 63 are connected to the same third pixel circuit 413, the first color sub-pixel 101 in the second pixel unit 120 may also include more fourth light-emitting areas S4 and the third color sub-pixel 103 may also include more sixth light-emitting areas S6, so as to further reduce the viewing angle of the privacy sub-pixel and optimize the privacy effect. The specific number can be designed according to the own process level, and the embodiments of the present invention do not limit this.

[0079] Figure 25 It is along Figure 23 A cross-sectional view of another display panel, taken from the diagram in DD', for reference. Figure 23 and Figure 25 In other embodiments, optionally, in the second pixel unit 120: the first color sub-pixel 101 includes two first light-emitting elements 61 and two first pixel circuits 411, the first light-emitting elements 61 and the fourth light-emitting area S4 are in one-to-one correspondence and are electrically connected to the first pixel circuits 411 in one-to-one correspondence; the third color sub-pixel 103 includes two third light-emitting elements 63 and two third pixel circuits 413, the third light-emitting elements 63 and the sixth light-emitting area S6 are in one-to-one correspondence and are electrically connected to the third pixel circuits 413 in one-to-one correspondence.

[0080] Specifically, in this embodiment, the first color sub-pixel 101 in the second pixel unit 120 includes two first light-emitting elements 61, and the third color sub-pixel 103 includes two third light-emitting elements 63. Correspondingly, the first color sub-pixel 101 in the second pixel unit 120 includes two fourth light-emitting areas S4, and the third color sub-pixel 103 includes two sixth light-emitting areas S6. The fourth light-emitting areas S4 correspond one-to-one with the first light-emitting elements 61, and the sixth light-emitting areas S6 correspond one-to-one with the third light-emitting elements 63.

[0081] Furthermore, in this embodiment, the two first light-emitting elements 61 corresponding to the first color sub-pixel 101 in the second pixel unit 120 are respectively connected to different first pixel circuits 411, and the two first light-emitting elements 61 can be lit independently. Similarly, the two third light-emitting elements 63 corresponding to the third color sub-pixel 103 are respectively connected to different third pixel circuits 413, and the two third light-emitting elements 63 can be lit independently. In this case, in the privacy mode, any second light-emitting element 62 corresponding to a second color sub-pixel 102 can form a light-emitting unit with the first light-emitting elements 61 and the third light-emitting elements 63 on both sides. Different second light-emitting elements 62 do not need to share the first light-emitting element 61 or the third light-emitting element 63. That is, in the privacy mode, the SPR algorithm is not required for display driving. In the sharing mode, the SPR algorithm is still required for display driving.

[0082] Figure 26 yes Figure 22 Another enlarged schematic diagram of the middle region Q2, see reference. Figure 26 Optionally, along the second direction Y, the length Y4 of the fourth light-emitting area S4 is greater than the length Y1 of the first light-emitting area S1, the length Y5 of the fifth light-emitting area S5 is greater than the length Y2 of the second light-emitting area S2, and the length Y6 of the sixth light-emitting area S6 is greater than the length Y3 of the third light-emitting area S3.

[0083] Specifically, in order to ensure the privacy protection effect, the fourth light-emitting area S4, the fifth light-emitting area S5, and the sixth light-emitting area S6 have a smaller length in the first direction X. By setting the fourth light-emitting area S4, the fifth light-emitting area S5, and the sixth light-emitting area S6 to have a larger length in the second direction Y, the light-emitting area of ​​the privacy protection sub-pixel can be guaranteed, thus ensuring the display effect in privacy protection mode.
