[0009] In a second aspect, an embodiment of the present invention provides another display panel, including:

Along a first direction, the third display area is located between the first display area and the second display area; the first display area includes at least a plurality of display sub-pixel groups, the second display area includes at least a plurality of anti-peeking sub-pixel groups, and the third display area includes a plurality of display sub-pixel groups and a plurality of anti-peeking sub-pixel groups;

[0011] Each display sub-pixel group includes at least one display sub-pixel, and each anti-peeking sub-pixel group includes at least two anti-peeking sub-pixels; at least along the first direction, the width of the anti-peeking sub-pixel is smaller than the width of the display sub-pixel; wherein, the first direction is parallel to the plane of the display panel;

[0012] The opening area of the display sub-pixels in the first display area is larger than the opening area of the display sub-pixels in the third display area, and the opening area of the anti-peeking sub-pixels in the second display area is larger than the opening area of the anti-peeking sub-pixels in the third display area;

[0016] For the display panel provided by the embodiment of the present invention, by setting the opening area of a plurality of display sub-pixels in the display sub-pixel group to be D1, and the opening area of a plurality of anti-peeking sub-pixels in the anti-peeking sub-pixel group to be D2, wherein, (D1 - D2) / D2 ≤ 50%, so that the opening area of a plurality of display sub-pixels in the display sub-pixel group is approximately equal to the opening area of a plurality of anti-peeking sub-pixels in the anti-peeking sub-pixel group. In this way, when the first display area includes at least a plurality of display sub-pixel groups and the second display area includes at least a plurality of anti-peeking sub-pixel groups, the aperture ratio of the display sub-pixels in the first display area can be approximately equal to the aperture ratio of the anti-peeking sub-pixels in the second display area. Furthermore, when the display sub-pixels in the first display area and the anti-peeking sub-pixels in the second display area are displayed simultaneously, the optical difference and life difference caused by the aperture ratio difference between the display sub-pixels in the first display area and the anti-peeking sub-pixels in the second display area can be reduced, thereby improving the boundary phenomenon between the first display area and the second display area and enhancing the display effect of the display panel.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0037] Figure 1 It is a schematic structural diagram of a display panel provided by an embodiment of the present invention. Refer to Figure 1 , the display panel includes at least two display areas, and the at least two display areas include a first display area AA1 and a second display area AA2. The first display area AA1 includes at least a plurality of display sub-pixel groups 10, and the second display area AA2 includes at least a plurality of anti-peeking sub-pixel groups 20. The display sub-pixel group 10 includes at least one display sub-pixel 110, and the anti-peeking sub-pixel group 20 includes at least two anti-peeking sub-pixels 210. At least along the first direction X, the width of the anti-peeking sub-pixel 210 is less than the width of the display sub-pixel 110, wherein the first direction X is parallel to the direction of the plane where the display panel is located. The opening area of the plurality of display sub-pixels 110 in the display sub-pixel group 10 is D1, and the opening area of the plurality of anti-peeking sub-pixels 210 in the anti-peeking sub-pixel group 20 is D2, wherein, (D1 - D2) / D2 ≤ 50%. In the first display state, at least the plurality of display sub-pixels 110 in the first display area AA1 are displayed, and in the second display state, at least the plurality of anti-peeking sub-pixels 210 in the second display area AA2 are displayed. Along the first direction X, the light-emitting viewing angle in the first display state is greater than the light-emitting viewing angle in the second display state.

[0038] Specifically, as Figure 1As shown, the first display area AA1 can be a shared display area, that is, the first display area AA1 can be a display area that can achieve a sharing function in different states. The second display area AA2 can be a privacy display area, that is, the second display area AA2 can be a display area that can perform a privacy function at least in a specific state. The first display area AA1 at least includes a plurality of display sub-pixel groups 10, and the second display area AA2 at least includes a plurality of privacy sub-pixel groups 20. As Figure 1 In the embodiment shown, only for example, the first display area AA1 only includes a plurality of display sub-pixel groups 10, and the second display area AA2 only includes a plurality of privacy sub-pixel groups 20 for illustration, but it is not limited thereto. In other embodiments, the first display area AA1 may further include privacy sub-pixel groups 20, and the second display area AA2 may further include display sub-pixel groups 10. Those skilled in the art can set according to needs. The display sub-pixel group 10 includes at least one display sub-pixel 110. As Figure 1 In the embodiment shown, the display sub-pixel group 10 includes three display sub-pixels 110, namely a red display sub-pixel 110a, a blue display sub-pixel 110c, and a green display sub-pixel 110b. The red display sub-pixel 110a, the blue display sub-pixel 110c, and the green sub-pixel 110b in the same display sub-pixel group 10 enclose the smallest repeating unit in a triangle, and a plurality of display sub-pixel groups 10 are arranged in an array. The privacy sub-pixel group 20 includes at least two privacy sub-pixels 210, wherein at least two privacy sub-pixels 210 correspond to privacy sub-pixels of the same color. As Figure 1 In the embodiment shown, the privacy sub-pixel group 20 includes six privacy sub-pixels 210, namely two red privacy sub-pixels 210a, two blue privacy sub-pixels 210c, and two green privacy sub-pixels 210b. The privacy sub-pixels 210 of the same color in the same privacy sub-pixel group 20 are taken as a whole, and the privacy sub-pixels 210 of different colors enclose the smallest repeating unit in a triangle, and a plurality of privacy sub-pixel groups 20 are arranged in an array.

[0039] It should be noted that if the privacy display of the privacy sub-pixel 210 is to be realized, it is necessary to set that at least along the first direction X, the width of the privacy sub-pixel 210 is smaller than the width of the display sub-pixel 110. Exemplarily, as Figure 1In the embodiment shown, the first direction X may be a horizontal direction. Further, along the horizontal direction, the width of the anti-peeking sub-pixel 210 is set to be much smaller than the width of the display sub-pixel 110. Thus, in the first direction X, due to the limitation of the pixel width, the light-emitting viewing angle of the anti-peeking sub-pixel 210 is restricted, such that the light-emitting viewing angle of the anti-peeking sub-pixel 210 in the first direction X is smaller than the light-emitting viewing angle of the display sub-pixel 110 in the first direction X, thereby realizing the anti-peeking display of the anti-peeking sub-pixel 210 in the first direction X, i.e., left and right anti-peeking. It can be understood that in other embodiments, up and down anti-peeking may also be set, that is, along the second direction Y, the width of the anti-peeking sub-pixel 210 is smaller than the width of the display sub-pixel 110, and the second direction Y intersects with the first direction X. The present invention does not limit this, and those skilled in the art can set it according to needs.

[0040] It can be understood that when realizing the left and right anti-peeking of the display area, it is necessary to set the anti-peeking sub-pixel group 20 to include two anti-peeking sub-pixels 210. The two anti-peeking sub-pixels 210 are arranged along the first direction X, and a light-shielding structure (not shown in the figure) also needs to be provided between the two anti-peeking sub-pixels 210. Thus, through the light-shielding structure between the two anti-peeking sub-pixels 210, it is further ensured that the light-emitting viewing angle of the anti-peeking sub-pixel 210 is smaller than the light-emitting viewing angle of the display sub-pixel 110.

[0041] Existing display panels need to have both a sharing function and an anti-peeking function in some application scenarios, that is, while realizing shared display in a part of the display area, anti-peeking display is realized in another part of the display area. Currently, a pixel segmentation scheme is usually adopted to divide normal sub-pixels into display sub-pixels and anti-peeking sub-pixels, so as to enable the anti-peeking display area to have the anti-peeking function. However, due to process limitations and various factors, the aperture of the divided anti-peeking sub-pixels is small, resulting in a large difference in aperture ratio between the anti-peeking sub-pixels in the anti-peeking display area and the non-divided sub-pixels in the shared display area. The difference in aperture ratio will cause optical differences and lifespan differences. Thus, when realizing the sharing function and the anti-peeking function simultaneously in different display areas, an obvious boundary will be formed in the transition area between the shared display area and the anti-peeking display area, resulting in a poor display effect of the display panel.

[0042] For this reason, in the embodiment of the present invention, the aperture area of multiple display sub-pixels 110 in the display sub-pixel group 10 is set to D1, and the aperture area of multiple anti-peeking sub-pixels 210 in the anti-peeking sub-pixel group 20 is set to D2, where (D1 - D2) / D2 ≤ 50%, so that the aperture area of multiple display sub-pixels 110 in the display sub-pixel group 10 is approximately equal to the aperture area of multiple anti-peeking sub-pixels 210 in the anti-peeking sub-pixel group 20. Exemplarily, such as Figure 1In the embodiment shown, since it is necessary to ensure that along the first direction X, the width of the anti-peeking sub-pixel 210 is smaller than the width of the display sub-pixel 110 to achieve the anti-peeking display of the anti-peeking sub-pixel 210, when preparing the display sub-pixel group 10, the length of the plurality of display sub-pixels 110 in the second direction Y can be reduced, thereby reducing the size of the display sub-pixel 110, so that the opening area of the display sub-pixel 110 is approximately equal to the opening area of the anti-peeking sub-pixel 210. Furthermore, when the first display area AA1 includes at least a plurality of display sub-pixel groups 10 and the second display area AA2 includes at least a plurality of anti-peeking sub-pixel groups 20, the aperture ratio of the display sub-pixels 110 in the first display area AA1 can be approximately equal to the aperture ratio of the anti-peeking sub-pixels 210 in the second display area AA2. In this way, in the first display state or the second display state, if a plurality of display sub-pixels 110 in the first display area AA1 are displayed while a plurality of anti-peeking sub-pixels 210 in the second display area AA2 are displayed, the optical difference and lifespan difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 can be reduced, thereby improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0043] It can be understood that along the first direction X, the light-emitting viewing angle in the first display state is larger than the light-emitting viewing angle in the second display state, that is, the first display state is a shared display state, and a plurality of display sub-pixels 110 are used for display, and the second display state is an anti-peeking display state, and a plurality of anti-peeking sub-pixels 210 are used for display.

[0044] It should be noted that Figure 1 Only by way of example, reducing the size of the display sub-pixel 110 to make the opening area of the display sub-pixel 110 approximately equal to the opening area of the anti-peeking sub-pixel 210 is taken as an example for illustration, but it is not limited thereto. In other embodiments, a normal sub-pixel can also be only divided into anti-peeking sub-pixels. Furthermore, compared with the solution of dividing a normal sub-pixel into a display sub-pixel and an anti-peeking sub-pixel, the size of the anti-peeking sub-pixel 210 can be increased to make the opening area of the display sub-pixel 110 approximately equal to the opening area of the anti-peeking sub-pixel 210, or while reducing the size of the display sub-pixel 110, the size of the anti-peeking sub-pixel 210 can be increased to further reduce the difference in the opening area between the display sub-pixel 110 and the anti-peeking sub-pixel 210, which can be set by those skilled in the art according to needs.

[0045] In summary, in the embodiments of the present invention, by setting the aperture area of multiple display sub-pixels in the display sub-pixel group to D1 and the aperture area of multiple anti-peeping sub-pixels in the anti-peeping sub-pixel group to D2, where (D1 - D2) / D2 ≤ 50%, the aperture areas of multiple display sub-pixels in the display sub-pixel group and the aperture areas of multiple anti-peeping sub-pixels in the anti-peeping sub-pixel group are approximately equal. The first display area includes at least multiple display sub-pixel groups, and the second display area includes at least multiple anti-peeping sub-pixel groups. Thus, in the first display state or the second display state, if there are multiple display sub-pixel groups in the first display area and multiple anti-peeping sub-pixel groups in the second display area that are simultaneously displaying, the optical difference and lifespan difference caused by the aperture ratio difference between the display sub-pixels in the first display area and the anti-peeping sub-pixels in the second display area can be reduced, thereby improving the demarcation phenomenon between the first display area and the second display area and enhancing the display effect of the display panel.

[0046] Optionally, on the basis of the above embodiments, Figure 2 is a schematic structural diagram of another display panel provided by the embodiments of the present invention. Refer to Figure 2 , the first display area AA1 includes multiple display sub-pixel groups 10, and the second display area AA2 includes multiple display sub-pixel groups 10 and multiple anti-peeping sub-pixel groups 20. In the first display state, multiple display sub-pixels 110 in the first display area AA1 and the second display area AA2 are displayed. In the second display state, multiple display sub-pixels 110 in the first display area AA1 are displayed, and multiple anti-peeping sub-pixels 210 in the second display area AA2 are displayed.

[0047] Specifically, as Figure 2In the embodiment shown, instead of dividing the sub-pixels in the first display area AA1, the size of the display sub-pixels 110 in the first display area AA1 is reduced during preparation, so that the first display area AA1 only includes a plurality of display sub-pixel groups 10. The sub-pixels in the second display area AA2 are divided so that one display sub-pixel group 10 and one anti-peeping sub-pixel group 20 in the second display area AA2 are combined into a minimum repeating unit, and a plurality of minimum repeating units are arranged in an array. In this way, in the first display state (shared display state), a plurality of display sub-pixels 110 in the first display area AA1 are displayed, a plurality of display sub-pixels 110 in the second display area AA2 are displayed, and a plurality of anti-peeping sub-pixels 210 are not displayed, so that both the first display area AA1 and the second display area AA2 realize the sharing function. In the second display state (anti-peeping display state), a plurality of display sub-pixels 110 in the first display area AA1 are displayed, a plurality of anti-peeping sub-pixels 210 in the second display area AA2 are displayed, and a plurality of display sub-pixels 110 are not displayed, that is, the first display area AA1 realizes the sharing function, and at the same time the second display area AA2 realizes the anti-peeping function. Since the opening areas of the plurality of display sub-pixels 110 in the display sub-pixel group 10 are approximately equal to the opening areas of the plurality of anti-peeping sub-pixels 210 in the anti-peeping sub-pixel group 20, the aperture ratio of the display sub-pixels 110 in the first display area AA1 is approximately equal to the aperture ratio of the anti-peeping sub-pixels 210 in the second display area AA2. In this way, the optical difference and life difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeping sub-pixels 210 in the second display area AA2 can be reduced, thereby improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0048] It should be noted that when at least one of the first display area AA1 and the second display area AA2 includes a display sub-pixel group 10 and an anti-peeping sub-pixel group 20, the anti-peeping sub-pixel group 20 and the display sub-pixel group 10 in the same display area are alternately arranged at intervals along the second direction Y, where the second direction Y intersects the first direction X. Exemplarily, as Figure 2 shown, when the second display area AA2 simultaneously includes a display sub-pixel group 10 and an anti-peeping sub-pixel group 20, along the second direction Y, the anti-peeping sub-pixel group 20 and the display sub-pixel group 10 are alternately arranged at intervals. In this way, in a minimum repeating unit composed of one anti-peeping sub-pixel group 20 and one display sub-pixel group 10, the area enclosed by the center connection lines of the plurality of display sub-pixels 110 overlaps with the area enclosed by the center connection lines of the plurality of anti-peeping sub-pixels 210, so that when the second display area AA2 switches between shared display and anti-peeping display, the difference in the display screen is small.

[0049] Optionally, on the basis of the above embodiment, continue to refer to Figure 2, the opening areas of the display sub-pixels 110 with the same color in the first display area AA1 and the second display area AA2 are the same. Specifically, continue to refer to Figure 2 , the sub-pixels in the first display area AA1 are not divided and only include the display sub-pixel group 10. In the second display area AA2, the sub-pixels are cut into two anti-peeping sub-pixels 210 and one display sub-pixel 110. Furthermore, the opening area of the display sub-pixel 110 in the first display area AA1 is reduced to be the same as the opening area of the cut display sub-pixel 110 in the second display area AA2 (for example, the opening area of the red display sub-pixel in the first display area AA1 is the same as the opening area of the red display sub-pixel in the second display area AA2, the opening area of the blue display sub-pixel in the first display area AA1 is the same as the opening area of the blue display sub-pixel in the second display area AA2, and the opening area of the green display sub-pixel in the first display area AA1 is the same as the opening area of the green display sub-pixel in the second display area AA2). The size of the display sub-pixel 110 in the first display area AA1 can be further reduced, so as to reduce the difference in the aperture ratio between the display sub-pixel 110 in the first display area AA1 and the anti-peeping sub-pixel 210 in the second display area AA2 in the second display state, and improve the demarcation phenomenon between the first display area AA1 and the second display area AA2. In addition, since the opening areas of the display sub-pixels 110 with the same color in the first display area AA1 and the second display area AA2 are the same, the aperture ratio of the display sub-pixel 110 in the first display area AA1 is equal to the aperture ratio of the display sub-pixel 110 in the second display area AA2. In the first display state, the display uniformity between the first display area AA1 and the second display area AA2 is achieved.

[0050] Optionally, on the basis of the above embodiment, Figure 3 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 3 , both the first display area AA1 and the second display area AA2 include a plurality of display sub-pixel groups 10 and a plurality of anti-peeping sub-pixel groups 20. In the first display state, the plurality of display sub-pixels 110 in the first display area AA1 and the second display area AA2 are displayed. In the second display state, the plurality of display sub-pixels 110 in the first display area AA1 are displayed, and the plurality of anti-peeping sub-pixels 210 in the second display area AA2 are displayed.

[0051] Specifically, as Figure 3In the embodiment shown, both the first display area AA1 and the second display area AA2 include normal sub-pixels, and the normal sub-pixels in the first display area AA1 and the second display area AA2 are both segmented so that the first display area AA1 includes both the display sub-pixel group 10 and the anti-peeking sub-pixel group 20 at the same time, and the second display area AA2 includes both the display sub-pixels 10 and the anti-peeking sub-pixel group 20 at the same time. In this way, in the first display state (shared display state), multiple display sub-pixels 110 in the first display area AA1 are displayed, and multiple anti-peeking sub-pixels 210 are not displayed. Multiple display sub-pixels 110 in the second display area AA2 are displayed, and multiple anti-peeking sub-pixels 210 are not displayed, so that both the first display area AA1 and the second display area AA2 achieve the sharing function. In the second display state (anti-peeking display state), multiple display sub-pixels 110 in the first display area AA1 are displayed, and multiple anti-peeking sub-pixels 210 are not displayed. Multiple anti-peeking sub-pixels 210 in the second display area AA2 are displayed, and multiple display sub-pixels 110 are not displayed. That is, the first display area AA1 realizes the sharing function, and at the same time the second display area AA2 realizes the anti-peeking function. Since in the first display area AA1, the size of the cut display sub-pixels 110 is smaller than that of the original normal sub-pixels, that is, the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 is reduced, thereby reducing the optical difference and life difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2, improving the boundary phenomenon between the first display area AA1 and the second display area AA2, and enhancing the display effect of the display panel.

[0052] It should be noted that on the basis of the above embodiment, the aperture areas of the display sub-pixels 110 with the same color in the first display area AA1 and the second display area AA2 are the same, and the aperture areas of the anti-peeking sub-pixels 210 with the same color are the same. Furthermore, the aperture ratio of the display sub-pixels 110 in the first display area AA1 is equal to the aperture ratio of the display sub-pixels 110 in the second display area AA2. Then, in the first display state, the display uniformity of the first display area AA1 and the second display area AA2 is achieved.

[0053] Optionally, on the basis of the above embodiment, Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 4 , the first display area AA1 includes multiple display sub-pixel groups 10, and the second display area AA2 includes multiple anti-peeking sub-pixel groups 20. In the first display state and the second display state, multiple display sub-pixels 110 in the first display area AA1 are displayed, and multiple anti-peeking sub-pixels 210 in the second display area AA2 are displayed.

[0054] Exemplarily, such asFigure 4 In the embodiment shown, instead of dividing the sub-pixels in the first display area AA1, the size of the display sub-pixels 110 in the first display area AA1 is reduced during fabrication, so that the first display area AA1 only includes a plurality of display sub-pixel groups 10. The sub-pixels in the second display area AA2 are divided into two anti-peeking sub-pixels 210, so that the second display area AA2 only includes a plurality of anti-peeking sub-pixel groups 20. Furthermore, compared with the solution of dividing the sub-pixels into one display sub-pixel 110 and two anti-peeking sub-pixels 210, the size of the anti-peeking sub-pixels 210 in the second display area AA2 can be increased. And since both the first display area AA1 and the second display area AA2 only include one type of sub-pixels, the first display area AA1 and the second display area AA2 cannot realize the switching between the anti-peeking function and the sharing function. Thus, in the first display state and the second display state, a plurality of display sub-pixels 110 in the first display area AA1 are displayed, and a plurality of anti-peeking sub-pixels 210 in the second display area AA2 are displayed. Since the size of the display sub-pixels 110 is reduced and the size of the anti-peeking sub-pixels 210 is increased in the embodiments of the present invention, that is, the optical difference and the lifetime difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 are further reduced, thereby further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0055] Optionally, on the basis of the above embodiments, Figure 5 is a schematic structural diagram of another display panel provided by the embodiments of the present invention, Figure 6 is Figure 5 a working schematic diagram in the second display state in Figure 5 and 6 , at least two display areas further include a third display area AA3. Along the first direction X, the third display area AA3 is located between the first display area AA1 and the second display area AA2. The third display area AA3 includes anti-peeking sub-pixel groups 20 and display sub-pixel groups 10. In the second display state, the anti-peeking sub-pixels 210 and some of the display sub-pixels 110 in the third display area AA3 are displayed, or the display sub-pixels 110 and some of the anti-peeking sub-pixels 210 in the third display area AA3 are displayed.

[0056] Specifically, as Figure 5In the embodiment shown, instead of dividing the sub-pixels in the first display area AA1, the size of the display sub-pixels 110 in the first display area AA1 is reduced during fabrication, so that the first display area AA1 only includes a plurality of display sub-pixel groups 10. The sub-pixels in the second display area AA2 are divided so that one display sub-pixel group 10 and one anti-peeking sub-pixel group 20 in the second display area AA2 are combined into a minimum repeating unit. A third display area AA3 is also provided between the first display area AA1 and the second display area AA2, and the third display area AA3 is a transition area between the first display area AA1 and the second display area AA2. The sub-pixels in the third display area AA3 are divided so that one display sub-pixel group 10 and one anti-peeking sub-pixel group 20 in the third display area AA3 are combined into a minimum repeating unit. Furthermore, as Figure 6 shown, in the second display state (anti-peeking display state), a plurality of display sub-pixels 110 in the first display area AA1 are displayed, a plurality of anti-peeking sub-pixels 210 in the second display area AA2 are displayed, and display sub-pixels 110 and some anti-peeking sub-pixels 210 in the third display area AA3 are displayed. On the one hand, by reducing the size of the display sub-pixels 110 in the first display area AA1, the optical difference and lifespan difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 are reduced. On the other hand, all the display sub-pixels 110 and some anti-peeking sub-pixels 210 in the third display area AA3 are displayed to create a transition effect between the first display area AA1 and the second display area AA2, further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0057] It should be noted that, as Figure 5 shown in the embodiment, in the third display area AA3, the anti-peeking sub-pixel groups 20 and the display sub-pixel groups 10 are arranged at intervals and alternately in the second direction Y. Then, as Figure 6 shown, in the second display state, some anti-peeking sub-pixels 210 in the third display area AA3 are displayed. In the triangular minimum repeating unit composed of three adjacent anti-peeking sub-pixel groups 20, only the red anti-peeking sub-pixels are displayed in one anti-peeking sub-pixel group, only the blue anti-peeking sub-pixels are displayed in another anti-peeking sub-pixel group, and only the green anti-peeking sub-pixels are displayed in the last anti-peeking sub-pixel group. In this way, the three anti-peeking sub-pixel groups form a minimum repeating unit for arrangement. It can be understood that the embodiments of the present invention do not limit which specific anti-peeking sub-pixels 210 are displayed, and those skilled in the art can set them as needed.

[0058] It should also be noted that in other embodiments, Figure 7 it is Figure 5Another working schematic diagram in the second display state, such as Figure 7 As shown, in the second display state, the third display area AA3 can also display all the anti-peeping sub-pixels 210 and some of the display sub-pixels 110. Among them, the display mode of some of the display sub-pixels 110 can be similar to that of Figure 6 some of the anti-peeping sub-pixels 210 in, and the present invention will not elaborate one by one.

[0059] Optionally, in another embodiment, Figure 8 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 9 is Figure 8 a working schematic diagram of the second display state in Figure 10 Figure 8 Another working schematic diagram of the second display state in. As Figures 8 - 10 In the shown embodiment, the first display area AA1, the second display area AA2, and the third display area AA3 all include normal sub-pixels, and the sub-pixels in the first display area AA1, the second display area AA2, and the third display area AA3 are all segmented so that the first display area AA1, the second display area AA2, and the third display area AA3 all simultaneously include a display sub-pixel group 10 and an anti-peeping sub-pixel group 20. In the first display state, the display sub-pixels 110 in the first display area AA1, the second display area AA2, and the third display area AA3 all perform display, so that the first display area AA1, the second display area AA2, and the third display area AA3 all achieve shared display. As Figure 9 As shown, in the second display state, the display sub-pixels 110 in the first display area AA1 perform display, the anti-peeping sub-pixels 210 in the second display area AA2 perform display, and all the display sub-pixels 110 and some of the anti-peeping sub-pixels 210 in the third display area AA3 perform display. On the one hand, by reducing the size of the display sub-pixels 110 in the first display area AA1, the optical difference and life difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeping sub-pixels 210 in the second display area AA2 are reduced. On the other hand, by setting that all the display sub-pixels 110 and some of the anti-peeping sub-pixels 210 in the third display area AA3 perform display in the second display state, a transition effect is provided between the first display area AA1 and the second display area AA2, further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0060] It should be noted that, as Figure 8 and Figure 9In the embodiment shown, in the third display area AA3, the anti-peeping sub-pixel groups 20 and the display sub-pixel groups 10 are arranged at intervals and alternately in the second direction Y. In the second display state, some of the anti-peeping sub-pixels 210 in the third display area AA3 are displayed. In the smallest triangular repeating unit composed of three adjacent anti-peeping sub-pixel groups 20, only the red anti-peeping sub-pixels are displayed in one anti-peeping sub-pixel group, only the blue anti-peeping sub-pixels are displayed in another anti-peeping sub-pixel group, and only the green anti-peeping sub-pixels are displayed in the last anti-peeping sub-pixel group. In this way, the three anti-peeping sub-pixel groups form the smallest repeating unit for arrangement. It can be understood that the embodiments of the present invention do not limit which specific anti-peeping sub-pixels 210 are displayed, and those skilled in the art can set them as needed.

[0061] It should also be noted that as Figure 10 shown, in the second display state, the third display area AA3 can also display all the anti-peeping sub-pixels 210 and some of the display sub-pixels 110. Among them, the display mode of some of the display sub-pixels 110 can be similar to Figure 9 the display mode of some of the anti-peeping sub-pixels 210 in

[0062] Optionally, in another embodiment, Figure 11 is a schematic structural diagram of another display panel provided by the embodiments of the present invention, Figure 12 is Figure 11 a schematic working diagram in the second display state in Figure 13 is Figure 11 another schematic working diagram in the second display state in Figures 11 - 13 Referring to Figure 12 and Figure 13As shown, in the first display state and the second display state, the display sub-pixels 110 are displayed in the first display area AA1, the anti-peeking sub-pixels 210 are displayed in the second display area AA2, all the anti-peeking sub-pixels 210 and some of the display sub-pixels 110 are displayed in the third display area AA3, or some of the anti-peeking sub-pixels 210 and all of the display sub-pixels 110 are displayed in the third display area AA3. On the one hand, by reducing the size of the display sub-pixels 110 in the first display area AA1 and increasing the size of the anti-peeking sub-pixels 210 in the second display area AA2, the optical difference and lifespan difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 are reduced. On the other hand, all the display sub-pixels 110 and some of the anti-peeking sub-pixels 210 in the third display area AA3 are displayed to create a transitional effect between the first display area AA1 and the second display area AA2, further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0063] It should be noted that when some of the anti-peeking sub-pixels 210 or some of the display sub-pixels 110 are displayed in the third display area AA3, the present invention does not limit which specific anti-peeking sub-pixels 210 or which specific display sub-pixels 110 are displayed, and those skilled in the art can set them as needed.

[0064] Optionally, on the basis of the above embodiments, continue to refer to Figure 1 , the display panel further includes a light extraction structure (not shown in the figure). The light extraction structure is arranged in the light-emitting direction of the display panel, and along the thickness direction of the display panel, the light extraction structure at least partially overlaps with the second display area AA2. Specifically, when multiple display sub-pixels 110 are displayed in the first display area AA1 and multiple anti-peeking sub-pixels 210 are displayed in the second display area AA2, on the one hand, the size of the display sub-pixels 110 in the first display area AA1 can be reduced to reduce the optical difference and lifespan difference caused by the aperture ratio difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2. On the other hand, a light extraction structure can be arranged on the second display area AA2 to increase the light output of the anti-peeking sub-pixels 210 in the second display area AA2, further improving the optical difference between the display sub-pixels 110 in the first display area AA1 and the anti-peeking sub-pixels 210 in the second display area AA2 and enhancing the display effect of the display panel.

[0065] Optionally, on the basis of the above embodiments, continue to refer to Figure 5, at least two display areas further include a third display area AA3. Along the first direction X, the third display area AA3 is located between the first display area AA1 and the second display area AA2. The third display area AA3 includes a privacy sub-pixel group 20 and a display sub-pixel group 10. Along the thickness direction of the display panel, the light extraction structure overlaps at least partially with the second display area AA2 and the third display area AA3 respectively. Specifically, the third display area AA3 is set between the first display area AA1 and the second display area AA2, and the third display area AA3 is a transition area between the first display area AA1 and the second display area AA2. On the one hand, by displaying through some display sub-pixels 110 and all privacy sub-pixels 210 in the third display area AA3, a transition effect is achieved between the first display area AA1 and the second display area AA2, improving the demarcation phenomenon between the first display area AA1 and the second display area AA2. On the other hand, a light extraction structure can also be set on the second display area AA2 and the third display area AA3, thereby increasing the light output of the privacy sub-pixels 210 in the second display area AA2, the privacy sub-pixels 210 in the third display area AA3, and some display sub-pixels 110, further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0066] Figure 14 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 15 is Figure 14 a schematic working diagram in the second display state. Refer to Figure 14 and Figure 15 , the display panel includes a first display area AA1, a second display area AA2, and a third display area AA3. Along the first direction X, the third display area AA3 is located between the first display area AA1 and the second display area AA2. The first display area AA1 at least includes a plurality of display sub-pixel groups 10, the second display area AA2 at least includes a plurality of privacy sub-pixel groups 20, and the third display area AA3 includes a plurality of display sub-pixel groups 10 and a plurality of privacy sub-pixel groups 20. The display sub-pixel group 10 includes at least one display sub-pixel 110, and the privacy sub-pixel group 20 includes at least two privacy sub-pixels 210. At least along the first direction X, the width of the privacy sub-pixel 210 is smaller than the width of the display sub-pixel 110, wherein the first direction X is parallel to the plane direction of the display panel. The opening area of the display sub-pixels 110 in the first display area AA1 is larger than the opening area of the display sub-pixels 110 in the third display area AA3, and the opening area of the privacy sub-pixels 210 in the second display area AA2 is larger than or equal to the opening area of the privacy sub-pixels 210 in the third display area AA3. In the second display state, some privacy sub-pixels 210 and some display sub-pixels 110 in the third display area AA3 are displayed, or some display sub-pixels 110 and some privacy sub-pixels 210 in the third display area AA3 are displayed.

[0067] Specifically, as Figure 14 shown, the first display area AA1 can be a shared display area, and the second display area AA2 can be an anti-peeking display area. The first display area AA1 includes a plurality of display sub-pixel groups 10, and the second display area AA2 includes at least a plurality of anti-peeking sub-pixel groups 20. Figure 14 In the embodiment shown, only the example that the second display area AA2 only includes a plurality of anti-peeking sub-pixel groups 20 is used for illustration, but it is not limited thereto. In other embodiments, the second display area AA2 may further include display sub-pixel groups 10, which can be set by those skilled in the art according to needs. The display sub-pixel group 10 includes at least one display sub-pixel 110. As Figure 14 shown in the embodiment, the display sub-pixel group 10 includes three display sub-pixels 110, namely a red display sub-pixel, a blue display sub-pixel, and a green display sub-pixel. The red display sub-pixel, the blue display sub-pixel, and the green sub-pixel in the same display sub-pixel group 10 enclose the smallest repeating unit in a triangle, and a plurality of display sub-pixel groups 10 are arranged in an array. The anti-peeking sub-pixel group 20 includes at least two anti-peeking sub-pixels 210, wherein at least two anti-peeking sub-pixels 210 correspond to anti-peeking sub-pixels of the same color. As Figure 14 shown in the embodiment, the anti-peeking sub-pixel group 20 includes six anti-peeking sub-pixels 210, namely two red anti-peeking sub-pixels, two blue anti-peeking sub-pixels, and two green anti-peeking sub-pixels. The anti-peeking sub-pixels 210 of the same color in the same anti-peeking sub-pixel group 20 are taken as a whole, and the anti-peeking sub-pixels 210 of different colors enclose the smallest repeating unit in a triangle, and a plurality of anti-peeking sub-pixel groups 20 are arranged in an array.

[0068] It should be noted that if the anti-peeking display of the anti-peeking sub-pixel 210 is to be realized, it is necessary to set that at least along the first direction X, the width of the anti-peeking sub-pixel 210 is smaller than the width of the display sub-pixel 110. Exemplarily, as Figure 14 shown in the embodiment, the first direction X can be the horizontal direction. Then, along the horizontal direction, the width of the anti-peeking sub-pixel 210 is set to be much smaller than the width of the display sub-pixel 110. In this way, in the first direction X, due to the limitation of the pixel width, the light-emitting viewing angle of the anti-peeking sub-pixel 210 will be limited, so that the light-emitting viewing angle of the anti-peeking sub-pixel 210 in the first direction X is smaller than the light-emitting viewing angle of the display sub-pixel 110 in the first direction X, thereby realizing the anti-peeking display of the anti-peeking sub-pixel 210 in the first direction X, that is, left and right anti-peeking. It can be understood that in other embodiments, up and down anti-peeking can also be set, that is, along the second direction Y, the width of the anti-peeking sub-pixel 210 is smaller than the width of the display sub-pixel 110, and the second direction Y intersects with the first direction X. The present invention is not limited thereto, and those skilled in the art can set it according to needs.

[0069] It can be understood that when implementing left and right anti-peeking in the display area, it is necessary to set the anti-peeking sub-pixel group 20 to include two anti-peeking sub-pixels 210. The two anti-peeking sub-pixels 210 are arranged along the first direction X, and a light-shielding structure (not shown in the figure) needs to be set between the two anti-peeking sub-pixels 210. In this way, through the light-shielding structure between the two anti-peeking sub-pixels 210, it is further ensured that the light-emitting viewing angle of the anti-peeking sub-pixel 210 is smaller than the light-emitting viewing angle of the display sub-pixel 110.

[0070] Existing display panels need to have both a sharing function and an anti-peeking function in some application scenarios, that is, while realizing shared display in a part of the display area, anti-peeking display is realized in another part of the display area. Currently, a pixel segmentation scheme is usually adopted to divide normal sub-pixels into display sub-pixels and anti-peeking sub-pixels, so as to make the anti-peeking display area have the anti-peeking function. However, due to process limitations and various factors, the aperture of the divided anti-peeking sub-pixels is small, resulting in a large difference in the aperture ratio between the anti-peeking sub-pixels in the anti-peeking display area and the non-divided sub-pixels in the shared display area. And the difference in aperture ratio will cause optical differences and lifespan differences. Furthermore, when realizing the sharing function and the anti-peeking function in different display areas at the same time, an obvious boundary will be formed in the transition area between the shared display area and the anti-peeking display area, resulting in a poor display effect of the display panel.

[0071] For this reason, in the embodiment of the present invention, a third display area AA3 is set between the first display area AA1 and the second display area AA2. The third display area AA3 is a transition area between the first display area AA1 and the second display area AA2. And the sub-pixels in the third display area AA3 are segmented so that a display sub-pixel group 10 and an anti-peeking sub-pixel group 20 in the third display area AA3 are combined into a minimum repeating unit. Since the display sub-pixels 110 in the first display area AA1 are not segmented and have the same size as normal sub-pixels, the aperture area of the display sub-pixels 110 in the first display area AA1 is larger than the aperture area of the display sub-pixels 110 in the third display area AA3. And the anti-peeking sub-pixels 210 in the second display area AA2 are formed after cutting, so the aperture area of the anti-peeking sub-pixels 210 in the second display area AA2 is larger than or equal to the aperture area of the anti-peeking sub-pixels 210 in the third display area AA3. As Figure 15As shown, in the second display state (privacy display state), multiple display sub-pixels 110 in the first display area AA1 are displayed, multiple privacy sub-pixels 210 in the second display area AA2 are displayed, and display sub-pixels 110 and some privacy sub-pixels 210 in the third display area AA3 are displayed. In this way, when the sharing function is realized in the first display area AA1 and the privacy function is realized in the second display area AA2, by setting all the display sub-pixels 110 and some privacy sub-pixels 210 in the third display area AA3 to be displayed, a transition effect is achieved between the first display area AA1 and the second display area AA2, further improving the demarcation phenomenon between the first display area AA1 and the second display area AA2 and enhancing the display effect of the display panel.

[0072] It should be noted that Figure 15 only for example, all the display sub-pixels 110 and some privacy sub-pixels 210 in the third display area AA3 are displayed for illustration, but it is not limited thereto. In other embodiments, some display sub-pixels 110 and all privacy sub-pixels 210 in the third display area AA3 can also be set to be displayed, and those skilled in the art can set according to needs.

[0073] It should also be noted that Figure 14 only for example, all the sub-pixels in the third display area AA3 are divided for illustration, but it is not limited thereto. In other embodiments, Figure 16 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 16 , in the third display area AA3, only some sub-pixels can also be divided. Exemplarily, the third display area AA3 includes multiple regions, and each region includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The multiple regions include multiple first regions S1, second regions S2, and third regions S3. Then, in the first region S1, the red sub-pixel is divided to form a red display sub-pixel and two red privacy sub-pixels, while the green sub-pixel and the blue sub-pixel are not divided. In the second region S2, the blue sub-pixel is divided to form a blue display sub-pixel and two blue privacy sub-pixels, while the green sub-pixel and the red sub-pixel are not divided. In the third region S3, the green sub-pixel is divided to form a green display sub-pixel and two green privacy sub-pixels, while the red sub-pixel and the blue sub-pixel are not divided. The first region S1, the second region S2, and the third region S3 form a triangular minimum repeating unit and are arranged in an array. It can be understood that the embodiment of the present invention does not limit the cutting method of the sub-pixels in the third display area AA3, as long as it is ensured that the third display area AA3 includes both the privacy sub-pixel group 20 and the display sub-pixel group 10.

[0074] In summary, in the embodiment of the present invention, a third display area is provided between the first display area and the second display area, and the third display area is a transition area between the first display area and the second display area. The third display area includes a privacy sub-pixel group and a display sub-pixel group, and the opening area of the display sub-pixels in the first display area is larger than the opening area of the display sub-pixels in the third display area. The opening area of the privacy sub-pixels in the second display area is greater than or equal to the opening area of the privacy sub-pixels in the third display area. In the second display state (privacy display state), a plurality of display sub-pixels in the first display area are displayed, a plurality of privacy sub-pixels in the second display area are displayed, and the display sub-pixels and some privacy sub-pixels in the third display area are displayed. In this way, when the sharing function is realized in the first display area and the privacy function is realized in the second display area, by setting all the display sub-pixels and some privacy sub-pixels in the third display area to be displayed, a transition effect is achieved between the first display area and the second display area, further improving the demarcation phenomenon between the first display area and the second display area and enhancing the display effect of the display panel.

[0075] Optionally, on the basis of the above embodiment, continue to refer to Figure 14 , the first display area AA1 includes a plurality of display sub-pixel groups 10, and both the second display area AA2 and the third display area AA3 include a plurality of display sub-pixel groups 10 and a plurality of privacy sub-pixel groups 20. In the first display state, a plurality of display sub-pixels 110 in the first display area AA1 and the second display area AA2 are displayed. In the second display state, a plurality of display sub-pixels 110 in the first display area AA1 are displayed, and a plurality of privacy sub-pixels 210 in the second display area AA2 are displayed.

[0076] Specifically, in the embodiment shown in Figure 14 , the sub-pixels in the first display area AA1 are not segmented, and the size of the sub-pixels is kept unchanged, so that the first display area AA1 only includes a plurality of display sub-pixel groups 10. The sub-pixels in the second display area AA2 and the third display area AA3 are segmented, so that one display sub-pixel group 10 and one privacy sub-pixel group 20 in the second display area AA2 are combined into a minimum repeating unit. One display sub-pixel group 10 and one privacy sub-pixel group 20 in the third display area AA3 are combined into a minimum repeating unit. At this time, the size of the privacy sub-pixels 210 in the third display area AA3 can be the same as the size of the privacy sub-pixels 210 in the second display area AA2. As shown in Figure 15As shown, in the second display state (the anti-peeping display state), multiple display sub-pixels 110 in the first display area AA1 display, multiple anti-peeping sub-pixels 210 in the second display area AA2 display, and multiple display sub-pixels 110 do not display, that is, the first display area AA1 realizes a sharing function, and the second display area AA2 realizes an anti-peeping function, and then by setting all the display sub-pixels 110 and part of the anti-peeping sub-pixels 210 in the third display area AA3 to display, there is a transition effect between the first display area AA1 and the second display area AA2, which further improves the boundary phenomenon between the first display area AA1 and the second display area AA2, and enhances the display effect of the display panel.

[0077] It should be noted that when at least one of the first display area AA1, the second display area AA2, and the third display area AA3 includes a display sub-pixel group 10 and an anti-peeping sub-pixel group 20, the anti-peeping sub-pixel group 20 and the display sub-pixel group 10 in the same display area are alternately arranged along the second direction Y, wherein the second direction Y intersects the first direction X. For example, Figure 14 As shown, when the second display area AA2 and the third display area AA3 include both the display sub-pixel group 10 and the anti-peeping sub-pixel group 20, along the second direction Y, the anti-peeping sub-pixel group 20 and the display sub-pixel group 10 are alternately arranged at intervals, so that in the minimum repeating unit consisting of an anti-peeping sub-pixel group 20 and a display sub-pixel group 10, a first area surrounded by the center lines of a plurality of display sub-pixels 110 overlaps with a second area surrounded by the center lines of a plurality of anti-peeping sub-pixels 210, so that when the second display area AA2 switches between shared display or anti-peeping display, the difference in the displayed image is small.

[0078] Optionally, based on the above embodiment, Figure 17 is a structural schematic diagram of another display panel provided by an embodiment of the present invention, Figure 18 yes Figure 17 A working diagram in the second display state. Figures 17 - 18 , the first display area AA1 includes a plurality of display sub-pixel groups 10, and the second display area AA2 includes a plurality of anti-peeping sub-pixel groups 20. In the first display state and the second display state, the plurality of display sub-pixels 110 in the first display area AA1 display, and the plurality of anti-peeping sub-pixels 210 in the second display area AA2 display.

[0079] For example, Figure 17In the illustrated embodiment, the sub-pixels in the first display area AA1 are not divided, and the size of the sub-pixels is kept unchanged, so that the first display area AA1 only includes a plurality of display sub-pixel groups 10. The sub-pixels in the second display area AA2 are divided into two anti-peeping sub-pixels 210, so that the second display area AA2 only includes a plurality of anti-peeping sub-pixel groups 20. The sub-pixels in the third display area AA3 are divided into one display sub-pixel 110 and two anti-peeping sub-pixels 210. Furthermore, the size of the display sub-pixel 110 in the first display area AA1 is larger than the size of the display sub-pixel 110 in the third display area AA3, and the size of the anti-peeping sub-pixel 210 in the second display area AA2 is larger than the size of the anti-peeping sub-pixel 210 in the third display area AA3. As Figure 18 shown, in the first display state and the second display state, a plurality of display sub-pixels 110 in the first display area AA1 are displayed, and a plurality of anti-peeping sub-pixels 210 in the second display area AA2 are displayed. That is, the first display area AA1 realizes the sharing function, and at the same time, the second display area AA2 realizes the anti-peeping function.
