Furthermore, the multiple sub-pixels in the second-type sub-pixel group are all sub-pixels from the second pixel. In privacy mode, since the sub-pixels in the second pixel do not emit light, the data voltage of the data lines electrically connected to the multiple sub-pixels in the second-type sub-pixel group can be a zero-brightness voltage. This reduces the power consumption caused by voltage jumps between the zero-brightness voltage and the privacy display brightness voltage, thus reducing the power consumption of the display panel in privacy mode.

[0049] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0050] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” “third,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “comprising” and similar terms mean that the element or object preceding “comprising” encompasses the element or object listed following “comprising” and its equivalents, and do not exclude other elements or objects. The terms “connection” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” “right,” “top,” and “bottom,” etc., are used only to indicate relative positional relationships, which may change accordingly when the absolute position of the described object changes. Furthermore, “A and / or B” indicates the presence of three cases: A and B, and A and B.

[0051] In related technologies, there exists a display panel with a privacy protection function. This display panel includes a substrate, multiple pixels, and multiple data lines. Multiple pixel arrays are arranged on the substrate. Each pixel includes multiple sub-pixels, and the multiple pixels include multiple first pixels and multiple second pixels. The maximum light emission angle of a sub-pixel in a first pixel is smaller than the maximum light emission angle of a sub-pixel in a second pixel. The sub-pixels in the multiple pixels include multiple sub-pixel groups arranged sequentially along a row direction. Each sub-pixel group includes multiple sub-pixels arranged sequentially along a column direction. Each sub-pixel group includes sub-pixels from both the first and second pixels. Multiple data lines are located on the substrate, and each data line extends along a column direction. Each data line is electrically connected to multiple sub-pixels in a sub-pixel group. The data lines control the light emission of sub-pixels in the first and second pixels respectively, enabling the display panel to switch between a privacy protection mode and a sharing mode.

[0052] However, in privacy mode, it is necessary to control the emission of sub-pixels in the first pixel while keeping the emission of sub-pixels in the second pixel off. Each sub-pixel group includes sub-pixels in the first pixel and sub-pixels in the second pixel. Each data line is electrically connected to multiple sub-pixels in a sub-pixel group. Thus, in privacy mode, the data voltage of each data line needs to switch between a no-brightness voltage and a privacy display brightness voltage, resulting in higher power consumption of the data lines and higher power consumption of the display panel in privacy mode.

[0053] To this end, embodiments of this disclosure provide a display panel that can switch between a privacy mode and a sharing mode, and can reduce power consumption in privacy mode.

[0054] Figure 1 is a schematic diagram of the pixel arrangement of a display panel according to an embodiment of the present disclosure. As shown in Figure 1, the display panel includes a substrate 10 and a plurality of pixels 2. The plurality of pixels 2 are arranged in an array on the substrate 10. Each pixel 2 includes a plurality of sub-pixels 21. The plurality of pixels 2 includes a plurality of first pixels 2a and a plurality of second pixels 2b. The maximum light emission angle of the sub-pixels 21 in the first pixels 2a is smaller than the maximum light emission angle of the sub-pixels 21 in the second pixels 2b. The sub-pixels 21 in the plurality of pixels 2 include a plurality of sub-pixel groups 20 arranged sequentially along a first direction x. Each sub-pixel group 20 includes a plurality of sub-pixels 21 arranged sequentially along a second direction y. The first direction x and the second direction y are perpendicular. The plurality of sub-pixel groups 20 include at least one first type sub-pixel group 20a and at least one second type sub-pixel group 20b. The first type sub-pixel group 20a includes a plurality of sub-pixels 21 in the first pixels 2a and a plurality of sub-pixels 21 in the second pixels 2b arranged alternately along the second direction y. The plurality of sub-pixels 21 in the second type sub-pixel group 20b are all sub-pixels 21 in the second pixels 2b.

[0055] Figure 2 is a schematic diagram of data line connections for a display panel according to an embodiment of this disclosure. As shown in Figure 2, the display panel further includes multiple data lines 30 located on the substrate 10, and each data line 30 extends along a second direction y. Each data line 30 is electrically connected to multiple sub-pixels 21 in a sub-pixel group 20. That is, all sub-pixels 21 in a sub-pixel group 20 are electrically connected to the same data line 30, and sub-pixels 21 connected to different data lines 30 belong to different sub-pixel groups 20.

[0056] In this embodiment of the present disclosure, each data line 30 is electrically connected to a plurality of sub-pixels 21 in a sub-pixel group 20. The plurality of sub-pixel groups 20 include at least one first type sub-pixel group 20a and at least one second type sub-pixel group 20b. The first type sub-pixel group 20a includes a plurality of sub-pixels 21 in a plurality of first pixels 2a and a plurality of sub-pixels 2b arranged alternately along the second direction y. In this way, the data line 30 can control the sub-pixels 21 in the first type sub-pixel group 20a to realize the switching of the display panel between the privacy mode and the sharing mode and ensure that the display panel has a better display effect in the privacy mode. Furthermore, the multiple sub-pixels 21 in the second type sub-pixel group 20b are all sub-pixels 21 in the second pixel 2b. In the privacy mode, since the sub-pixels 21 in the second pixel 2b do not emit light, the data voltage of the data line 30 electrically connected to the multiple sub-pixels 21 in the second type sub-pixel group 20b can be a no-brightness voltage. This can reduce the power consumption caused by the voltage jump between the no-brightness voltage and the privacy display brightness voltage of the data line, thereby reducing the power consumption of the display panel in the privacy mode.

[0057] Optionally, the first direction x is one of the row direction and the column direction, and the second direction y is the other of the row direction and the column direction. This facilitates the setting of wiring along the row and column directions to control the emission of sub-pixels 21 in the first pixel 2a and the second pixel 2b, thereby enabling the display panel to switch between privacy mode and sharing mode.

[0058] In this embodiment of the disclosure, the first direction x is the row direction and the second direction y is the column direction. In other embodiments, the first direction x can be the column direction and the second direction y can be the row direction.

[0059] In one possible implementation, sub-pixel 21 can be electrically connected to data line 30 via a via connection point. The center of the orthographic projection of the via connection point of sub-pixel 21 on substrate 10 and the center of the orthographic projection of sub-pixel 21 on substrate 10 are located at different positions. Since the display panel can illuminate sub-pixels 21 row by row in sequence to display the image, in any two adjacent sub-pixel groups 20, the via connection points of corresponding sub-pixels 21 can be arranged in the same row to facilitate illuminating sub-pixels 21 row by row.

[0060] Parts (a) and (b) in Figure 2 can both represent the connection relationship between the sub-pixels 21 and the data lines 30 in the display panel shown in Figure 1. Referring to Figures 1 and 2, the sub-pixels 21 in each pixel 2 include a first-color sub-pixel 21a, a second-color sub-pixel 21b, and a third-color sub-pixel 21c. Multiple sub-pixels 21 in the first-type sub-pixel group 20a are all second-color sub-pixels 21b, and the second-type sub-pixel group 20b includes multiple first-color sub-pixels 21a and multiple third-color sub-pixels 21c arranged alternately along the second direction y.

[0061] The display panel illuminates sub-pixels 21 row by row in sequence. Each data line 30 provides data voltage to sub-pixels 21 in a sub-pixel group 20 in the second direction y at different time periods to control the brightness of sub-pixels 21 in the sub-pixel group 20. In privacy mode, in the first type of sub-pixel group 20a, sub-pixels 21 in the first pixel 2a need to emit light for privacy display, while sub-pixels 21 in the second pixel 2b need not emit light. This allows sub-pixels 21 in the first pixel 2a and the second pixel 2b in the first type of sub-pixel group 20a to be sub-pixels 21b of the second color. In privacy mode, only the sub-pixels 21b of the second color in the first type of sub-pixel group 20a need to switch between no brightness and privacy brightness. Since the brightness voltage required for different colors of sub-pixels 21 when emitting light may be different, compared with the fact that sub-pixels 21 of two colors in the first type of sub-pixel group 20a need to switch between no brightness and privacy brightness, the power consumption of the data line 30 electrically connected to multiple sub-pixels 21 in the first type of sub-pixel group 20a due to data voltage switching can be reduced in privacy mode, thereby further reducing the power consumption of the display panel in privacy mode.

[0062] Optionally, the plurality of sub-pixel groups 20 further includes at least one third type sub-pixel group 20c, wherein the plurality of sub-pixels 21 in the third type sub-pixel group 20c are all sub-pixels 21 in the first pixel 2a. Thus, in privacy mode, the plurality of sub-pixels 21 in the third type sub-pixel group 20c need to emit light for privacy display, and the data line 30 electrically connected to the plurality of sub-pixels 21 in the third type sub-pixel group 20c only needs to provide privacy display brightness voltage, without the need for voltage switching between no brightness voltage and privacy display brightness voltage, thereby reducing the power consumption of the data line 30 due to data voltage switching.

[0063] Optionally, the number of colors of the plurality of sub-pixels 21 in the third type sub-pixel group 20c is the same as the number of colors of the plurality of sub-pixels 21 in the second type sub-pixel group 20b. For example, the plurality of sub-pixels 21 in the second type sub-pixel group 20b includes sub-pixels 21 of two colors, and the plurality of sub-pixels 21 in the third type sub-pixel group 20c also includes sub-pixels 21 of two colors; or, the plurality of sub-pixels 21 in the second type sub-pixel group 20b includes sub-pixels 21 of one color, and the plurality of sub-pixels 21 in the third type sub-pixel group 20c also includes sub-pixels 21 of one color.

[0064] For example, the third type of subpixel group 20c includes a plurality of first color subpixels 21a and a plurality of third color subpixels 21c arranged alternately along the second direction y. This can improve the uniformity of the display effect of the display panel in privacy mode and sharing mode.

[0065] Optionally, the plurality of subpixel groups 20 include a plurality of first subpixel groups 20d and a plurality of second subpixel groups 20e arranged alternately along a first direction x. Each first subpixel group 20d includes a plurality of first color subpixels 21a and a plurality of third color subpixels 21c arranged alternately along a second direction y. Each second subpixel group 20e includes a plurality of second color subpixels 21b arranged sequentially along the second direction y. Arranging subpixels 21 of different colors in this manner can improve the display effect of the display panel.

[0066] It should be noted that subpixel groups 20 can be divided into first subpixel group 20d and second subpixel group 20e based on the color of subpixel 21, or they can be divided into first type subpixel group 20a, second type subpixel group 20b, and third type subpixel group 20c based on the light emission of subpixel 21 in privacy mode and sharing mode. For example, in the display panel shown in Figures 1 and 2, the first four subpixel groups 20 from left to right are first subpixel group 20d, second subpixel group 20e, first subpixel group 20d and second subpixel group 20e, and are respectively second type subpixel group 20b, first type subpixel group 20a, third type subpixel group 20c and first type subpixel group 20a.

[0067] For example, the first color sub-pixel 21a is a red (R) sub-pixel, the second color sub-pixel 21b is a green (G) sub-pixel, and the third color sub-pixel 21c is a blue (B) sub-pixel. Setting the red and blue sub-pixels in the first sub-pixel group 20d and the green sub-pixel in the second sub-pixel group 20e can ensure a better display effect of the display panel.

[0068] In other embodiments, the first color sub-pixel 21a can be a blue sub-pixel, the second color sub-pixel 21b can be a green sub-pixel, and the third color sub-pixel 21c can be a red sub-pixel; this disclosure does not limit this.

[0069] For example, multiple first pixels 2a and multiple second pixels 2b are alternately arranged in the third direction m and the fourth direction n, where the third direction m and the fourth direction n intersect, and the third direction m intersects both the first direction x and the second direction y, while the fourth direction n intersects both the first direction x and the second direction y. This makes the distribution of the first pixels 2a and the second pixels 2b on the substrate 10 more uniform, thereby improving the display effect of the display panel in privacy mode and sharing mode.

[0070] Optionally, in any pixel 2, at least one sub-pixel 21 is a sub-pixel 21 in the first type of sub-pixel group 20a. This can further improve the uniformity of the distribution of the first pixel 2a and the second pixel 2b, which is beneficial to improving the display effect.

[0071] Referring to Figures 1 and 2, in any first pixel 2a and any second pixel 2b, the number of sub-pixels 21 of each color is equal. This reduces the difference in display effect between the privacy mode and the sharing mode, ensuring better uniformity of the display effect between the privacy mode and the sharing mode.

[0072] For example, each sub-pixel 21 in pixel 2 includes a first color sub-pixel 21a, two second color sub-pixels 21b, and a third color sub-pixel 21c.

[0073] Optionally, in any pixel 2, the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c intersects the line connecting the centers of the two second color sub-pixels 21b. The extension direction of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c is one of the first direction x and the second direction y, and the extension direction of the line connecting the centers of the two second color sub-pixels 21b is the other of the first direction x and the second direction y. Arranging the sub-pixels 21 of each color in each pixel 2 in this way can improve the display effect of the display panel.

[0074] As shown in Figure 1, in any pixel 2, the extension direction of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c is the second direction y, and the extension direction of the line connecting the centers of the two second color sub-pixels 21b is the first direction x. In Figure 2, each data line 30 provides data voltage to a sub-pixel 21 in a sub-pixel group 20 in the second direction y to control the light emission brightness of the sub-pixel 21 in the sub-pixel group 20. This allows the first sub-pixel group 20d to be either a second type sub-pixel group 20b or a third type sub-pixel group 20c, and the second sub-pixel group 20e to be a first type sub-pixel group 20a. That is, in the privacy mode, only the second color sub-pixel 21b in the second sub-pixel group 20e needs to switch between no brightness and privacy brightness, while the first sub-pixel group 20d maintains privacy brightness or no brightness. Therefore, the power consumption of the data line 30 electrically connected to multiple sub-pixels 21 in the second sub-pixel group 20e due to data voltage switching can be reduced in the privacy mode.

[0075] As shown in Figure 1, in any pixel 2, the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c passes through the midpoint of the line connecting the centers of the two second color sub-pixels 21b. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from bottom to top, and the two second color sub-pixels 21b are arranged from left to right. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c are arranged in a diamond-like pattern. The connection method between sub-pixels 21 and the data lines in Figure 1 can adopt the connection method shown in Figure 2.

[0076] As shown in Figure 2, in any pixel 2, the line connecting two second-color sub-pixels 21b passes through either the first-color sub-pixel 21a or the third-color sub-pixel 21c. Here, the line connecting two sub-pixels 21 can refer to the line connecting the via connection points of the two sub-pixels 21. This facilitates control of the sub-pixels 21 through control signals in the row and column directions, simplifying the control algorithm. In Figure 2, in odd-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged sequentially in the order of first-color sub-pixel 21a, second-color sub-pixel 21b, third-color sub-pixel 21c, second-color sub-pixel 21b; in even-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged sequentially in the order of third-color sub-pixel 21c, second-color sub-pixel 21b, first-color sub-pixel 21a, second-color sub-pixel 21b. In other embodiments, the line connecting two sub-pixels 21 can also refer to the line connecting the centers of the two sub-pixels 21; this disclosure does not limit this.

[0077] As shown in part (a) of Figure 2, in any pixel 2, the line connecting two second-color sub-pixels 21b passes through the third-color sub-pixel 21c. The first-color sub-pixels 21a and the third-color sub-pixels 21c are arranged from bottom to top, and the two second-color sub-pixels 21b are arranged from left to right. Furthermore, in any pixel 2, one first-color sub-pixel 21a, two second-color sub-pixels 21b, and one third-color sub-pixel 21c are arranged in a similar T-shape. As shown in part (b) of Figure 2, in any pixel 2, the line connecting two second-color sub-pixels 21b passes through the first-color sub-pixel 21a. The first-color sub-pixels 21a and the third-color sub-pixels 21c are arranged from bottom to top, and the two second-color sub-pixels 21b are arranged from left to right. Furthermore, in any pixel 2, one first-color sub-pixel 21a, two second-color sub-pixels 21b, and one third-color sub-pixel 21c are arranged in a similar inverted T-shape.

[0078] Since the light-emitting efficiency of sub-pixels 21 in the first pixel 2a is different from that of sub-pixels 21 in the second pixel 2b, different gamma voltages can be provided for sub-pixels 21 of the same color in the first pixel 2a and the second pixel 2b in the sharing mode. This ensures that the display brightness of sub-pixels 21 of the same color is the same in the sharing mode and guarantees the white balance of the sharing mode. As shown in part (a) of Figure 2, in the sharing mode, a second gamma voltage can be provided for the first color sub-pixels 21a located in odd-numbered rows, and a first gamma voltage can be provided for the first color sub-pixels 21a located in even-numbered rows; a first gamma voltage can be provided for the second color sub-pixels 21b located in odd-numbered rows, and a second gamma voltage can be provided for the second color sub-pixels 21b located in even-numbered rows; a first gamma voltage can be provided for the third color sub-pixels 21c located in odd-numbered rows, and a second gamma voltage can be provided for the third color sub-pixels 21c located in even-numbered rows. Here, the first gamma voltage and the second gamma voltage are the gamma voltages of sub-pixels 21 of the same color in the first pixel 2a and the second pixel 2b in the shared mode, respectively. The voltage values ​​of the first gamma voltage and the second gamma voltage are different. Furthermore, for sub-pixels 21 of different colors, the voltage values ​​of the first gamma voltage and the second gamma voltage are also different.

[0079] As shown in part (b) of Figure 2, in the sharing mode, a second gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a first gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; a second gamma voltage can be provided to the second color sub-pixel 21b located in odd-numbered rows, and a first gamma voltage can be provided to the second color sub-pixel 21b located in even-numbered rows; a first gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a second gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows.

[0080] In shared mode, both sub-pixels 21 in the first pixel 2a and the second pixel 2b emit light, while in privacy mode, only sub-pixels 21 in the first pixel 2a emit light. The arrangement of the emitted sub-pixels 21 differs between shared mode and privacy mode. Therefore, different gamma voltages can be provided for sub-pixels 21 of the same color in the first pixel 2a in shared mode and privacy mode to ensure white balance in both modes.

[0081] For example, in privacy mode, a third gamma voltage can be provided to sub-pixels 21 in the second pixel 2a. This third gamma voltage is different from the first gamma voltage. Here, the first gamma voltage and the third gamma voltage are respectively the gamma voltages of sub-pixels 21 of the same color in the first pixel 2a in shared mode and privacy mode, and the voltage values ​​of the first gamma voltage and the third gamma voltage are different. Furthermore, for sub-pixels 21 of different colors, the voltage values ​​of the first gamma voltage and the third gamma voltage are also different.

Parts (a) and (b) in Figure 4 can both represent the connection relationship between sub-pixels 21 and data lines 30 in the display panel shown in Figure 3. The arrangement of sub-pixel group 20 in Figure 3 is the same as that in Figure 1, and the arrangement of sub-pixel group 20 in Figure 4 is the same as that in Figure 2. The difference between the display panel shown in Figure 3 and the display panel shown in Figure 1 is that in any pixel 2 shown in Figure 3, the first color sub-pixel 21a and the third color sub-pixel 21c are arranged from top to bottom.

[0083] The difference between the display panel shown in Figure 4 and the display panel shown in Figure 2 is that in Figure 4, the sub-pixels 21 in the odd-numbered rows 21 are arranged in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b from left to right, while the sub-pixels 21 in the even-numbered rows 21 are arranged in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b from left to right. As shown in part (a) of Figure 4, in any pixel 2, the line connecting two second color sub-pixels 21b passes through the first color sub-pixel 21a. The first color sub-pixels 21a and third color sub-pixels 21c are arranged from top to bottom, and the two second color sub-pixels 21b are arranged from left to right. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c are arranged in a similar T-shape. As shown in part (b) of Figure 4, in any pixel 2, the line connecting the two second-color sub-pixels 21b passes through the third-color sub-pixel 21c. The first-color sub-pixels 21a and the third-color sub-pixels 21c are arranged from top to bottom, and the two second-color sub-pixels 21b are arranged from left to right. In any pixel 2, one first-color sub-pixel 21a, two second-color sub-pixels 21b, and one third-color sub-pixel 21c are arranged in a similar inverted T-shape.

[0084] As shown in part (a) of Figure 4, in the sharing mode, a first gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a second gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; a first gamma voltage can be provided to the second color sub-pixel 21b located in odd-numbered rows, and a second gamma voltage can be provided to the second color sub-pixel 21b located in even-numbered rows; a second gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a first gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows. As shown in part (b) of Figure 4, in the sharing mode, a first gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a second gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; a second gamma voltage can be provided to the second color sub-pixel 21b located in odd-numbered rows, and a first gamma voltage can be provided to the second color sub-pixel 21b located in even-numbered rows; a second gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a first gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows. The voltage values ​​of the first gamma voltage and the second gamma voltage are different, and the voltage values ​​of the first gamma voltage and the second gamma voltage are different for sub-pixels 21 of different colors.

[0085] Figure 5 is a schematic diagram of pixel arrangement of another display panel provided in an embodiment of the present disclosure, and Figure 6 is a schematic diagram of data line connection of another display panel provided in an embodiment of the present disclosure. Parts (a) and (b) in Figure 6 can both represent the connection relationship between sub-pixels 21 and data lines 30 in the display panel shown in Figure 5. Referring to Figures 5 and 6, the first type of sub-pixel group 20a may include a plurality of first color sub-pixels 21a and a plurality of third color sub-pixels 21c arranged alternately along the second direction y. The plurality of sub-pixels 21 in the second type of sub-pixel group 20b may all be second color sub-pixels 21b, and the plurality of sub-pixels 21 in the third type of sub-pixel group 20c may all be second color sub-pixels 21b. Thus, in the privacy mode, the two colors of sub-pixels 21 in the first type of sub-pixel group 20a need to switch between no brightness and privacy brightness.

[0086] In the display panel shown in part (a) of Figures 5 and 6, the first four sub-pixel groups 20 from left to right are the first sub-pixel group 20d, the second sub-pixel group 20e, the first sub-pixel group 20d and the second sub-pixel group 20e, and are respectively the first type sub-pixel group 20a, the third type sub-pixel group 20c, the first type sub-pixel group 20a and the second type sub-pixel group 20b. In the display panel shown in part (b) of Figure 6, the first four sub-pixel groups 20 from left to right are the first sub-pixel group 20d, the second sub-pixel group 20e, the first sub-pixel group 20d and the second sub-pixel group 20e, and are respectively the first type sub-pixel group 20a, the second type sub-pixel group 20b, the first type sub-pixel group 20a and the third type sub-pixel group 20c.

[0087] As shown in Figure 5, in any pixel 2, the extension direction of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c is the first direction x, and the extension direction of the line connecting the centers of the two second color sub-pixels 21b is the second direction y. In Figure 6, each data line 30 provides data voltage to the sub-pixel 21 in a sub-pixel group 20 in the second direction y to control the light emission brightness of the sub-pixel 21 in the sub-pixel group 20. This allows the first sub-pixel group 20d to be the first type sub-pixel group 20a, and the second sub-pixel group 20e to be either the second type sub-pixel group 20b or the third type sub-pixel group 20c. That is, in the privacy mode, the first color sub-pixel 21a and the third color sub-pixel 21c in the first sub-pixel group 20d need to switch between no brightness and privacy brightness, while the second sub-pixel group 20e maintains privacy brightness or no brightness.

[0088] As shown in Figure 5, in any pixel 2, the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c passes through the midpoint of the line connecting the centers of the two second color sub-pixels 21b. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from left to right, and the two second color sub-pixels 21b are arranged from top to bottom, with one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c arranged in a similar diamond shape. The connection method between sub-pixels 21 and the data lines in Figure 5 can adopt the connection method shown in Figure 6.

[0089] As shown in Figure 6, in any pixel 2, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through a second color sub-pixel 21b. In Figure 6, in odd-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, second color sub-pixel 21b, while in even-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, second color sub-pixel 21b.

[0090] As shown in part (a) of Figure 6, in any pixel 2, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through the upper second color sub-pixel 21b of the two second color sub-pixels 21b. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from left to right, and the two second color sub-pixels 21b are arranged from top to bottom. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c are arranged in a similar T-shape. As shown in part (b) of Figure 6, in any pixel 2, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through the lower second color sub-pixel 21b of the two second color sub-pixels 21b. The first color sub-pixel 21a and the third color sub-pixel 21c are arranged from left to right, and the two second color sub-pixels 21b are arranged from top to bottom. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b and one third color sub-pixel 21c are arranged in a similar inverted T shape.

[0091] As shown in part (a) of Figure 6, in the shared mode, a first gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a second gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; the second color sub-pixels 21b are all located in even-numbered columns, and the second sub-pixel groups 20e are all located in even-numbered columns. A first gamma voltage can be provided to the second color sub-pixels 21b in the odd-numbered second sub-pixel groups 20e from left to right, and a second gamma voltage can be provided to the second color sub-pixels 21b in the even-numbered second sub-pixel groups 20e; a first gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a second gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows. Here, from left to right, the second column of sub-pixels 21 is the first second sub-pixel group 20e, the fourth column of sub-pixels 21 is the second second sub-pixel group 20e, the sixth column of sub-pixels 21 is the third second sub-pixel group 20e, and the eighth column of sub-pixels 21 is the fourth second sub-pixel group 20e. As shown in part (b) of Figure 6, in the sharing mode, a second gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a first gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; a second gamma voltage can be provided to the second color sub-pixel 21b in the odd-numbered second sub-pixel group 20e from left to right, and a first gamma voltage can be provided to the second color sub-pixel 21b in the even-numbered second sub-pixel group 20e; a first gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a second gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows. The voltage values ​​of the first gamma voltage and the second gamma voltage are different, and the voltage values ​​of the first gamma voltage and the second gamma voltage are different for sub-pixels 21 of different colors.

[0092] Figure 7 is a schematic diagram of pixel arrangement of another display panel provided in an embodiment of the present disclosure, and Figure 8 is a schematic diagram of data line connection of another display panel provided in an embodiment of the present disclosure. Parts (a) and (b) in Figure 8 can both represent the connection relationship between sub-pixels 21 and data lines 30 in the display panel shown in Figure 7. The arrangement of sub-pixel group 20 in Figure 7 is the same as that in Figure 5, and the arrangement of sub-pixel group 20 in parts (a) and (b) of Figure 8 is the same as that in parts (a) and (b) of Figure 6, respectively. The difference between the display panel shown in Figure 7 and the display panel shown in Figure 5 is that in any pixel 2 shown in Figure 7, the first color sub-pixel 21a and the third color sub-pixel 21c are arranged from right to left.

[0093] The difference between the display panel shown in Figure 8 and the display panel shown in Figure 6 is that in Figure 8, the sub-pixels 21 in the odd-numbered rows 21 are arranged in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b from left to right, while the sub-pixels 21 in the even-numbered rows 21 are arranged in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b from left to right. As shown in part (a) of Figure 8, in any pixel 2, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through the upper second color sub-pixel 21b of the two second color sub-pixels 21b. The first color sub-pixel 21a and the third color sub-pixel 21c are arranged from right to left, and the two second color sub-pixels 21b are arranged from top to bottom. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c are arranged in a similar T-shape. As shown in part (b) of Figure 8, in any pixel 2, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through the lower of the two second color sub-pixels 21b. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from right to left, and the two second color sub-pixels 21b are arranged from top to bottom. In any pixel 2, one first color sub-pixel 21a, two second color sub-pixels 21b, and one third color sub-pixel 21c are arranged in a similar inverted T-shape.

[0094] As shown in part (a) of Figure 8, in the sharing mode, a first gamma voltage can be provided to the first color sub-pixel 21a located in the odd-numbered row, and a second gamma voltage can be provided to the first color sub-pixel 21a located in the even-numbered row; a first gamma voltage can be provided to the second color sub-pixel 21b in the odd-numbered second sub-pixel group 20e from left to right, and a second gamma voltage can be provided to the second color sub-pixel 21b in the even-numbered second sub-pixel group 20e; a first gamma voltage can be provided to the third color sub-pixel 21c located in the odd-numbered row, and a second gamma voltage can be provided to the third color sub-pixel 21c located in the even-numbered row. As shown in part (b) of Figure 8, in the sharing mode, a second gamma voltage can be provided to the first color sub-pixel 21a located in odd-numbered rows, and a first gamma voltage can be provided to the first color sub-pixel 21a located in even-numbered rows; a second gamma voltage can be provided to the second color sub-pixel 21b in the odd-numbered second sub-pixel group 20e from left to right, and a first gamma voltage can be provided to the second color sub-pixel 21b in the even-numbered second sub-pixel group 20e; a first gamma voltage can be provided to the third color sub-pixel 21c located in odd-numbered rows, and a second gamma voltage can be provided to the third color sub-pixel 21c located in even-numbered rows. The voltage values ​​of the first gamma voltage and the second gamma voltage are different, and the voltage values ​​of the first gamma voltage and the second gamma voltage are different for sub-pixels 21 of different colors.

[0095] Figure 9 is a schematic diagram of pixel arrangement of another display panel provided in an embodiment of the present disclosure, and Figure 10 is a schematic diagram of data line connection of another display panel provided in an embodiment of the present disclosure. Parts (a) and (b) in Figure 10 can both represent the connection relationship between sub-pixels 21 and data lines 30 in the display panel shown in Figure 9. Referring to Figures 9 and 10, the number of sub-pixels 21 in the first pixel 2a is less than the number of sub-pixels 21 in the second pixel 2b. This can reduce the number of sub-pixels 21 in the first pixel 2a and reduce the power consumption of the display panel in privacy mode. For example, in Figures 1 to 8, in privacy mode, four sub-pixels 21 can be used to emit light together to form a first pixel 2a, and in Figures 9 and 10, in privacy mode, three sub-pixels 21 can be used to emit light together to form a first pixel 2a.

[0096] For example, each sub-pixel 21 in the first pixel 2a includes a first color sub-pixel 21a, a second color sub-pixel 21b, and a third color sub-pixel 21c.

[0097] Optionally, in any first pixel 2a, the second color sub-pixel 21b is located on the first side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c, and the extension direction of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c is either the first direction x or the second direction y. This ensures a better display effect of the display panel in privacy mode.

[0098] As shown in Figure 9, in any first pixel 2a, the extension direction of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c is the second direction y, and the second color sub-pixel 21b is located on the first side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c. In the display panel, all sub-pixels 21 except those in the first pixel 2a are sub-pixels in the second pixel 2b.

[0099] As shown in Figure 9, in any first pixel 2a, the extension direction of the line connecting the center of the second color sub-pixel 21b and the center of the first color sub-pixel 21a intersects both the first direction x and the second direction y. Similarly, the extension direction of the line connecting the center of the second color sub-pixel 21b and the center of the third color sub-pixel 21c intersects both the first direction x and the second direction y. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from bottom to top. In any first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in a similar triangular pattern. The connection method between the sub-pixels 21 and the data lines in Figure 9 can adopt the connection method shown in Figure 10.

[0100] In Figure 10, in odd-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b. In even-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b. As shown in part (a) of Figure 10, in any first pixel 2a, the extension direction of the line connecting the second color sub-pixel 21b and the third color sub-pixel 21c is the first direction x. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from bottom to top, and the second color sub-pixels 21b and the third color sub-pixels 21c are arranged from left to right. In any first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in a figure-7 shape. As shown in part (b) of Figure 10, in any first pixel 2a, the extension direction of the line connecting the second color sub-pixel 21b and the first color sub-pixel 21a is the first direction x. The first color sub-pixel 21a and the third color sub-pixel 21c are arranged from bottom to top, and the second color sub-pixel 21b and the first color sub-pixel 21a are arranged from right to left. In any first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in an L-shape.

[0101] As shown in Figure 10, in shared mode, all sub-pixels 21 in the first pixel 2a and the second pixel 2b emit light, and the arrangement of the sub-pixels 21 is a sub-pixel rendering (SPR) arrangement. In privacy mode, only the sub-pixels 21 in the first pixel 2a emit light, and the arrangement is a traditional sub-pixel (Real RGB) arrangement. The arrangement of the emitted sub-pixels 21 differs between shared mode and privacy mode. Therefore, different gamma voltages can be provided for sub-pixels 21 of the same color in the first pixel 2a in shared mode and privacy mode to ensure white balance in both modes.

[0102] The display panel shown in Figure 9 can be based on the display panel shown in Figure 1, except that a second color sub-pixel 21b on the second side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c in each first pixel 1a in Figure 1 is replaced with a sub-pixel 21 in the second pixel 2b. The display panel shown in part (a) of Figure 10 can be based on the display panel shown in part (a) of Figure 2, except that a second color sub-pixel 21b on the second side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c in each first pixel 1a in part (a) of Figure 2 is replaced with a sub-pixel 21 in the second pixel 2b. The display panel shown in part (b) of Figure 10 can be based on the display panel shown in part (b) of Figure 2, except that a second color sub-pixel 21b on the second side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21 in each first pixel 1a in part (b) of Figure 2 is replaced with a sub-pixel 21 in the second pixel 2b.

[0103] In the display panel shown in part (a) of Figures 9 and 10, the first four sub-pixel groups 20 from left to right are the first sub-pixel group 20d, the second sub-pixel group 20e, the first sub-pixel group 20d and the second sub-pixel group 20e, respectively, and are the second type sub-pixel group 20b, the first type sub-pixel group 20a, the third type sub-pixel group 20c and the second type sub-pixel group 20b, respectively. In the display panel shown in part (b) of Figure 10, the first four sub-pixel groups 20 from left to right are the first sub-pixel group 20d, the second sub-pixel group 20e, the first sub-pixel group 20d and the second sub-pixel group 20e, respectively, and are the second type sub-pixel group 20b, the second type sub-pixel group 20b, the third type sub-pixel group 20c and the first type sub-pixel group 20a, respectively.

[0104] Figure 11 is a schematic diagram of a data cable connection for another display panel provided in an embodiment of this disclosure. The arrangement of sub-pixel group 20 in part (a) of Figure 11 is the same as that in part (b) of Figure 10.

[0105] The difference between the display panel shown in Figure 11 and the display panel shown in Figure 10 is that in Figure 11, the sub-pixels 21 in the odd-numbered rows 21 are arranged sequentially from left to right in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b, while the sub-pixels 21 in the even-numbered rows 21 are arranged sequentially from left to right in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b. As shown in part (a) of Figure 11, in any first pixel 2a, the extension direction of the line connecting the second color sub-pixel 21b and the first color sub-pixel 21a is the first direction x. The first color sub-pixel 21a and the third color sub-pixel 21c are arranged from top to bottom, and the second color sub-pixel 21b and the first color sub-pixel 21a are arranged from right to left. In any given first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in a "7" shape, mirrored in the left-right direction. As shown in part (b) of Figure 11, in any given first pixel 2a, the extension direction of the line connecting the second color sub-pixel 21b and the third color sub-pixel 21c is the first direction x. The first color sub-pixel 21a and the third color sub-pixel 21c are arranged from top to bottom, and the second color sub-pixel 21b and the third color sub-pixel 21c are arranged from left to right. In any given first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in an L-shape, mirrored in the left-right direction.

[0106] The display panel shown in part (a) of Figure 11 can be based on the display panel shown in part (a) of Figure 4, except that a second color sub-pixel 21b on the second side of the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c in each first pixel 1a of Figure 4 (a) is replaced with a sub-pixel 21 in the second pixel 2b. Similarly, the display panel shown in part (b) of Figure 11 can be based on the display panel shown in part (b) of Figure 4, except that a second color sub-pixel 21b on the second side of the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c in each first pixel 1a of Figure 4 (b) is replaced with a sub-pixel 21 in the second pixel 2b.

[0107] Figure 12 is a schematic diagram of pixel arrangement of another display panel provided in an embodiment of the present disclosure, and Figure 13 is a schematic diagram of data line connection of another display panel provided in an embodiment of the present disclosure. Figure 13 shows the connection relationship between sub-pixels 21 and data lines 30 in the display panel shown in Figure 12. Referring to Figures 12 and 13, the number of sub-pixels 21 in the first pixel 2a is less than the number of sub-pixels 21 in the second pixel 2b. For example, in privacy mode, three sub-pixels 21 can emit light together to form a first pixel 2a.

[0108] As shown in Figures 12 and 13, each sub-pixel 21 in the first pixel 2a includes a first color sub-pixel 21a, a second color sub-pixel 21b, and a third color sub-pixel 21c.

[0109] As shown in Figure 12, in any first pixel 2a, the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c extends in the first direction x, and the second color sub-pixel 21b is located on the first side of the line connecting the centers of the first color sub-pixel 21a and the third color sub-pixel 21c. In the display panel, all sub-pixels 21 except those in the first pixel 2a are sub-pixels in the second pixel 2b.

[0110] As shown in Figure 12, in any first pixel 2a, the extension direction of the line connecting the center of the second color sub-pixel 21b and the center of the first color sub-pixel 21a intersects both the first direction x and the second direction y. Similarly, the extension direction of the line connecting the center of the second color sub-pixel 21b and the center of the third color sub-pixel 21c intersects both the first direction x and the second direction y. The first color sub-pixels 21a and the third color sub-pixels 21c are arranged from left to right. In any first pixel 2a, one first color sub-pixel 21a, one second color sub-pixel 21b, and one third color sub-pixel 21c are arranged in a similar triangular pattern. The connection method between the sub-pixels 21 and the data lines in Figure 12 can adopt the connection method shown in Figure 13.

[0111] In Figure 13, in odd-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b. In even-numbered rows of sub-pixels 21, the sub-pixels 21 from left to right repeat and are arranged in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b. As shown in Figure 13, in any first pixel 2a, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through a second color sub-pixel 21b, and the extension direction of the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c is the first direction x. That is, in any first pixel 2a, the line connecting the second color sub-pixel 21b and the first color sub-pixel 21a extends in the first direction x, and the line connecting the second color sub-pixel 21b and the third color sub-pixel 21c extends in the first direction x. The first color sub-pixel 21a, the second color sub-pixel 21b, and the third color sub-pixel 21c are arranged in a rectangle from left to right.

[0112] The display panel shown in Figure 12 can be based on the display panel shown in Figure 5, except that in each first pixel 1a in Figure 5, one of the second-color sub-pixels 21b on the second side of the line connecting the centers of the first-color sub-pixels 21a and the third-color sub-pixels 21c is replaced with a sub-pixel 21 in the second pixel 2b. The display panel shown in Figure 13 can be based on the display panel shown in part (a) of Figure 6, except that in each first pixel 1a in part (a), one of the second-color sub-pixels 21b outside the line connecting the first-color sub-pixels 21a and the third-color sub-pixels 21c is replaced with a sub-pixel 21 in the second pixel 2b. That is, in each first pixel 1a, one of the second-color sub-pixels 21b located in a different row from the other three sub-pixels 21 is replaced with a sub-pixel 21 in the second pixel 2b.

[0113] In the display panel shown in Figures 12 and 13, the first four sub-pixel groups 20 from left to right are the first sub-pixel group 20d, the second sub-pixel group 20e, the first sub-pixel group 20d and the second sub-pixel group 20e, and are respectively the first type sub-pixel group 20a, the first type sub-pixel group 20a, the first type sub-pixel group 20a and the second type sub-pixel group 20b. No third type sub-pixel group is set.

[0114] Figure 14 is a schematic diagram of data line connection for another display panel provided in an embodiment of this disclosure. The display panel shown in Figure 14 differs from the display panel shown in Figure 13 in that, in Figure 14, the sub-pixels 21 in the odd-numbered rows 21 are arranged sequentially from left to right in the order of third color sub-pixel 21c, second color sub-pixel 21b, first color sub-pixel 21a, and second color sub-pixel 21b; while the sub-pixels 21 in the even-numbered rows 21 are arranged sequentially from left to right in the order of first color sub-pixel 21a, second color sub-pixel 21b, third color sub-pixel 21c, and second color sub-pixel 21b. As shown in Figure 14, in any first pixel 2a, the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c passes through a second color sub-pixel 21b, and the extension direction of the line connecting the first color sub-pixel 21a and the third color sub-pixel 21c is the first direction x. That is, in any first pixel 2a, the extension direction of the line connecting the second color sub-pixel 21b and the first color sub-pixel 21a is the first direction x, and the extension direction of the line connecting the second color sub-pixel 21b and the third color sub-pixel 21c is also the first direction x. The third color sub-pixel 21c, the second color sub-pixel 21b, and the first color sub-pixel 21a are arranged in a rectangle from left to right. The difference between part (a) and part (b) of Figure 14 is that in part (a) of Figure 14, the sub-pixels 21 in the first pixel 2a are all located in odd-numbered rows, while in part (b) of Figure 14, the sub-pixels 21 in the first pixel 2a are all located in even-numbered rows.

[0115] The display panel shown in part (a) of Figure 14 can be based on the display panel shown in part (a) of Figure 8, by changing one second-color sub-pixel 21b outside the line connecting the first-color sub-pixel 21a and the third-color sub-pixel 21c in each first pixel 1a of Figure 8 to a sub-pixel 21 in the second pixel 2b. That is, in each first pixel 1a, the second-color sub-pixel 21b located in a different row from the other three sub-pixels 21 is changed to a sub-pixel 21 in the second pixel 2b. The display panel shown in part (b) of Figure 14 can be based on the display panel shown in part (b) of Figure 8, by changing one second-color sub-pixel 21b outside the line connecting the first-color sub-pixel 21a and the third-color sub-pixel 21c in each first pixel 1a of Figure 8 to a sub-pixel 21 in the second pixel 2b. That is, in each first pixel 1a, the second-color sub-pixel 21b located in a different row from the other three sub-pixels 21 is changed to a sub-pixel 21 in the second pixel 2b.

[0116] The arrangement of subpixel group 20 in part (a) of Figure 14 is the same as that in part (b) of Figure 14. In the display panel shown in part (b) of Figure 14, the first four subpixel groups 20 from left to right are the first subpixel group 20d, the second subpixel group 20e, the first subpixel group 20d and the second subpixel group 20e, and are respectively the first type subpixel group 20a, the second type subpixel group 20b, the first type subpixel group 20a and the first type subpixel group 20a. No third type subpixel group is provided.

[0117] As shown in Figures 1 to 14, the substrate 10 has a plurality of pixel regions arranged in an array. The plurality of pixel regions include a plurality of first pixel regions 10a and a plurality of second pixel regions 10b. Each first pixel 2a is located in a first pixel region 10a, and each second pixel 2b is located in a second pixel region 10b.

[0118] Figure 15 is a partial structural schematic diagram of a display panel in the first pixel region according to an embodiment of the present disclosure. As shown in Figure 15, each sub-pixel 21 includes a light-emitting unit 22 and a color resist block 23 sequentially stacked along a direction away from the substrate 10. The display panel also includes a plurality of dimming structures 40, each dimming structure 40 being located in a first pixel region and between the light-emitting unit 22 and the color resist block 23. The side of the dimming structure 40 away from the substrate 10 has a plurality of first openings 401. A portion of each color resist block 23 in the first pixel region is located in one of the first openings 401, and the refractive index of the dimming structure 40 is less than the refractive index of the color resist block 23.

[0119] The arrows in Figure 15 indicate the propagation path of the light emitted by the light-emitting unit 22 at the edge of the first opening 401, as shown in Figure 15. In the first pixel area, when the light emitted by the light-emitting unit 22 is directed from the color resist block 23 to the dimming structure 40 at the edge of the first opening 401, since the refractive index of the dimming structure 40 is less than that of the color resist block 23, total internal reflection is easily generated when the light enters the film layer with a lower refractive index from the film layer with a higher refractive index. Therefore, total internal reflection is easily generated at the interface between the color resist block 23 and the dimming structure 40, thereby causing this part of the light to converge towards the center of the first opening 401 through the dimming structure 40, and exiting with a smaller viewing angle range, achieving the purpose of privacy display and improving the light emission efficiency of the sub-pixel 21 in the first pixel.

[0120] For example, the dimming structure 40 is made of an organic insulating material or an inorganic insulating material. For example, the dimming structure 40 can be made of polyimide (PI) or silicon dioxide, etc.

[0121] In other embodiments, the display panel can also change the viewing angle range of light emission through other structures as needed. For example, a black matrix or the like can be set as a light-shielding structure, and the area and thickness of the orthogonal projection of the light-shielding structure on the substrate 10 can be set to absorb light with a large viewing angle range to achieve privacy display. This disclosure does not limit this.

[0122] In this embodiment of the present disclosure, the depth of the first opening 401 in a direction perpendicular to the surface of the substrate 10 is equal to the thickness of the dimming structure 40. In other embodiments, the depth of the first opening 401 may be less than the thickness of the dimming structure 40, and this disclosure does not impose any limitations on this.

[0123] Optionally, the outer contour of the orthographic projection of the first opening 401 onto the substrate 10 is a rounded rectangle, a rectangle, or a circle.

[0124] Optionally, the orthographic projection of the end of the first opening 401 closest to the substrate 10 onto the substrate 10 is located inside the orthographic projection of the end of the first opening 401 furthest from the substrate 10 onto the substrate 10. Thus, the shape of the first opening 401 in a cross-section perpendicular to the surface of the substrate 10 can be trapezoidal. When the light emitted by the light-emitting unit 22 is directed by the color resist block 23 towards the sidewall of the first opening 401, the light is more likely to converge towards the center of the first opening 401, thereby effectively reducing the viewing angle range of the emitted light and improving the light emission efficiency of the sub-pixel 21 in the first pixel.

[0125] For example, the outer contour of the orthographic projection of the first opening 401 onto the substrate 10 is a rounded rectangle.

[0126] For example, the display panel also includes a pixel definition layer 41, which has a plurality of pixel openings 411, and a light-emitting unit 22 is disposed in each pixel opening 411.

[0127] Figure 16 is a partial structural diagram of a display panel in the second pixel region according to an embodiment of the present disclosure. Referring to Figures 1, 15 and 16, the plurality of pixel openings 411 include a plurality of second openings 411a and a plurality of third openings 411b, the second openings 411a being located in the first pixel region 10a and the third openings 411b being located in the second pixel region 10b.

[0128] Optionally, in the pixel opening 411 where the light-emitting unit 22 of the sub-pixel 21 of the same color is located, the opening area of ​​the second opening 411a is greater than or less than the opening area of ​​the third opening 411b. Here, the opening area can refer to the area of ​​the orthographic projection of the end of the pixel opening 411 closest to the substrate 10 onto the substrate 10.

[0129] The lifespan of the light-emitting unit 22 is related to its usage time and current density during use. The longer the usage time, the shorter the lifespan. Similarly, the higher the current density during use, the shorter the lifespan. The current density is directly proportional to the current and inversely proportional to the opening area. The color resist block 23 of the sub-pixel 21 in the first pixel area 10a is equipped with a dimming structure 40. The light-emitting efficiency of the sub-pixel 21 in the first pixel area 10a is relatively high. In order to ensure that the display brightness of the sub-pixels 21 of the same color in the first pixel area 10a and the sub-pixels 21 of the same color in the second pixel area 10b is the same in the sharing mode, the current of the light-emitting unit 22 of the sub-pixel 21 in the first pixel area 10a is relatively small, and the current density is relatively small. Meanwhile, in privacy mode, the light-emitting unit 22 in the first pixel area 10a emits light, while the light-emitting unit 22 in the second pixel area 10b does not emit light. In shared mode, the light-emitting units 22 in both the first pixel area 10a and the second pixel area 10b emit light. Therefore, the area of ​​the second opening 411a and the third opening 411b can be adjusted to adjust the current density of the light-emitting units in different pixel areas. Combined with their respective usage time, the lifespan of the light-emitting units 22 in the first pixel area 10a and the second pixel area 10b can be better matched, thereby improving the reliability of the display panel.

[0130] For example, the opening areas of the pixel openings 411 where the light-emitting units 22 of the sub-pixels 21 of different colors are located are different.

[0131] For example, in the same sub-pixel 21, the orthogonal projection of the light-emitting unit 22 on the substrate 10 is located inside the orthogonal projection of the color resist block 23 on the substrate 10.

[0132] As shown in Figures 15 and 16, the display panel further includes an encapsulation layer 42, a touch metal layer 43, a black matrix 44, and a cover layer 45. The encapsulation layer 42 is located between the plurality of light-emitting units 22 and the plurality of color resist blocks 23. The touch metal layer 43 is located between the encapsulation layer 42 and the plurality of color resist blocks 23, and in the first pixel area, the dimming structure 40 covers the surface of the touch metal layer 43 away from the substrate 10 and the sidewalls of the touch metal layer 43. The black matrix 44 is located on the surface of the plurality of color resist blocks 23 away from the substrate 10, and the orthographic projection of the touch metal layer 43 on the substrate 10 is located inside the orthographic projection of the black matrix 44 on the substrate 10. In the first pixel area, the orthographic projection of the black matrix 44 on the substrate 10 is located inside the orthographic projection of the dimming structure 40 on the substrate 10. The cover layer 45 is located on the surface of the black matrix 44 and the plurality of color resist blocks 23 away from the substrate 10.

[0133] The encapsulation layer 42 protects multiple light-emitting units 22, blocking external water and oxygen and improving the reliability of the display panel. Touch functionality is achieved through the touch metal layer 43, and the dimming structure 40 protects the touch metal layer 43 within the first pixel area. The black matrix 44 increases color contrast and prevents light leakage. The orthographic projection of the black matrix 44 onto the substrate 10 is located inside the orthographic projection of the dimming structure 40 onto the substrate 10, reducing the absorption of light reflected by the dimming structure 40 by the black matrix 44, thereby improving the display brightness in privacy mode and sharing mode. The cover layer 45 protects the black matrix 44 and multiple color resist blocks 23.

[0134] Optionally, the display panel further includes a touch protection layer 46, which is located in the second pixel area and covers the surface of the touch metal layer 43 away from the substrate 10 and the sidewalls of the touch metal layer 43. A plurality of color resist blocks 23 in the second pixel area are located on the surface of the touch protection layer 46 away from the substrate 10. In this way, the touch protection layer 46 can protect the touch metal layer 43 in the second pixel area and facilitates planarization between the plurality of color resist blocks 23 and the touch metal layer 43 in the second pixel area.

[0135] For example, the surface of the touch protection layer 46 away from the substrate 10 is planar.

[0136] Optionally, the dimming structure 40 and the touch protection layer 46 are in the same layer. Here, "in the same layer" means formed by the same patterning process, or in contact with the same surface of the same film layer. This simplifies the process flow for fabricating the dimming structure 40.

[0137] Figure 17 is a partial structural diagram of the second pixel area of ​​another display panel provided in an embodiment of this disclosure. As shown in Figure 17, a touch protection layer may not be provided in the second pixel area of ​​the display panel.

[0138] Alternatively, the display panel may be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, a micro light-emitting diode (Micro LED) display panel, or a liquid crystal (LC) display panel, etc.

[0139] The following explanation uses an OLED display panel as an example.

[0140] Optionally, the substrate 10 can be a drive backplane.

[0141] Optionally, the drive backplane can be a low-temperature polycrystalline oxide (LTPO) backplane or a low-temperature polycrystalline silicon (LTPS) backplane.

[0142] For example, the substrate 10 includes a substrate driving circuit layer that is stacked sequentially along the direction close to the plurality of light-emitting units 22.

[0143] Optionally, the driving circuit layer includes multiple thin-film transistors (TFTs).

[0144] Taking LTPO backplane as an example, multiple TFTs include low-temperature polycrystalline silicon TFTs and metal oxide TFTs.

[0145] Optionally, the driving circuit layer further includes a bottom light-shielding layer, a buffer layer, a first active layer, a first gate insulating layer, a first gate layer, a first insulating layer, a second gate layer, a second gate insulating layer, a second active layer, a third gate insulating layer, a third gate layer, an interlayer dielectric layer, a first source-drain layer, a passivation layer, a first planarization layer, a second source-drain layer, and a second planarization layer, stacked sequentially along the direction close to the plurality of light-emitting units 22.

[0146] For example, the data line is on the same layer as at least one of the first source-drain layer and the second source-drain layer.

[0147] As shown in Figures 15 to 17, the light-emitting unit 22 includes an anode 221, a light-emitting layer 222 and a cathode 223 stacked sequentially in a direction away from the substrate 10. A portion of the light-emitting layer 222 of the light-emitting unit 22 is located in the corresponding pixel opening 411, and the cathodes 223 of multiple light-emitting units 22 are connected.

[0148] For example, the light-emitting layer 222 may include an electron injection layer (EIL), an electron transport layer (ETL), a hole block layer (HBL), a light-emitting material layer, a hole transport layer (HTL), a hole injection layer (HIL), and an electron blocking layer (EBL) stacked sequentially in a direction away from the anode 221.

[0149] It should be noted that the film layer structure of the above-described display panel is only an example. In other embodiments, the display panel may include more or fewer film layer structures, which can be adjusted according to actual needs. This disclosure does not limit this.

[0150] Figure 18 is a flowchart of a control method for a display panel according to an embodiment of this disclosure. This control method can be used to control any of the aforementioned display panels. As shown in Figure 18, the control method includes:

[0151] In step S501, when the display panel is in shared mode, the sub-pixels in the first pixel and the second pixel are controlled to emit light.

[0152] In step S502, when the display panel is in privacy mode, the sub-pixels in the first pixel are controlled to emit light.

[0153] It should be noted that the steps S501 to S502 above are not in any particular order.

[0154] The beneficial effects of the embodiments disclosed herein are shown in Figures 1 to 17, and will not be repeated here.

[0155] Optionally, each sub-pixel includes a light-emitting unit, and the light-emitting efficiency of the sub-pixel in the first pixel is greater than that of the sub-pixel in the second pixel. The above step S501 may include: when the display panel is in a shared mode, controlling the light-emitting unit in the first pixel to emit light at a first brightness, and controlling the light-emitting unit in the second pixel to emit light at a second brightness, wherein the second brightness is greater than the first brightness, and the first brightness and the second brightness are respectively the brightness of the light-emitting units of the sub-pixels of the same color in the first pixel and the second pixel.

[0156] Since the light-emitting efficiency of the sub-pixels in the first pixel is greater than that in the second pixel, the light-emitting unit of the sub-pixels in the first pixel can achieve a higher display brightness with a lower light-emitting brightness. The second brightness is greater than the first brightness, which is beneficial to ensure that the display brightness of each sub-pixel of the same color is the same in the shared mode, thereby improving the display effect of the shared mode.

[0157] Optionally, step S502 may include: when the display panel is in privacy mode, controlling the light-emitting unit in the first pixel to emit light at a third brightness, the third brightness being different from the first brightness, wherein the first brightness and the third brightness are respectively the brightness of the light-emitting units of the same color sub-pixels in the first pixel in sharing mode and privacy mode.

[0158] Since the light-emitting units of the sub-pixels in the first pixel emit light in both the privacy mode and the sharing mode, the first brightness and the third brightness are different, which helps to ensure the white balance of the privacy mode and thus improves the display effect of the privacy mode.

[0159] Figure 19 is a structural block diagram of a control device for a display panel according to an embodiment of this disclosure. This control device can be used to control any of the aforementioned display panels. As shown in Figure 19, the control device 1000 includes a first control module 1001 and a second control module 1002. The first control module 1001 is used to control the emission of sub-pixels in the first pixel and the second pixel when the display panel is in a shared mode. The second control module 1002 is used to control the emission of sub-pixels in the first pixel when the display panel is in a privacy mode.

[0160] It should be noted that the control device for the display panel provided in the above embodiments is only illustrated by the division of the above functional modules and units when controlling the display panel. In practical applications, the above functions can be assigned to different functional modules and units as needed, that is, the internal structure of the device can be divided into different functional modules and units to complete all or part of the functions described above.
