Description

Pixel arrangement structure, display panel and display device Technical Field

[0001] The present disclosure relates to, but is not limited to, the field of display technology, and in particular to a pixel arrangement structure, a display panel, and a display device. Background Art

[0002] Active matrix organic light emitting diode (AMOLED) displays require an anti-spying function in certain privacy scenarios, known as an anti-spying mode, but require sharing screen information in certain public scenarios, known as a sharing mode. This requires AMOLED displays to have both an anti-spying and a sharing mode, with the ability to switch between these modes at any time. For example, when viewing information in public, especially when presenting a payment code or entering a password, the mobile phone display can be switched to an anti-spying mode, and to a sharing mode in other situations. Furthermore, for in-vehicle application displays, the display can be switched to an anti-spying mode when the co-pilot is viewing entertainment information, and to a sharing mode in other situations.

[0003] Current display panels cannot be directly switched between an anti-peeping state and a sharing state, or the display effect is poor in the anti-peeping state or the sharing state.

[0048] Details

[0049] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other in any manner.

[0050] Please refer to Figures 1 to 12 for the pixel arrangement structure of the embodiment of the present disclosure. This pixel arrangement structure includes multiple regular display areas S1 and multiple anti-peeping display areas S2. The regular display areas S1 and the anti-peeping display areas S2 are configured to be independently controlled to light up and extinguish. The regular display areas S1 and the anti-peeping display areas S2 both extend along a first direction. The multiple regular display areas S1 and the multiple anti-peeping display areas S2 are arranged alternately along a second direction, with the first and second directions intersecting. As can be seen from the above, the regular display areas S1 and the anti-peeping display areas S2 are effectively separated, facilitating the light shielding structure 20 to shield the regular display areas S1 and the anti-peeping display areas S2 from light, thereby preventing the influence of the shielding effects of the two, and achieving a better display effect.

[0051] In some exemplary embodiments, as shown in FIG1 , the regular display area S1 may include a plurality of first repeating units 1, each of which is arranged sequentially along a first direction. The anti-peeping display area S2 may include a plurality of second repeating units 2, each of which is also arranged sequentially along the first direction. All first repeating units 1 within the regular display area S1 and all second repeating units 2 within the anti-peeping display area S2 are arranged together to form an array. The first direction may be perpendicular to the second direction, the row direction of the array may be aligned with the first direction, and the column direction of the array may be aligned with the second direction. A row of first repeating units 1 and a row of second repeating units 2 are arranged alternately. Within a single column, the first repeating units 1 and the second repeating units 2 are arranged alternately, i.e., the second repeating units 2 and the first repeating units 1 are arranged alternately along the second direction. The regular display area S1 and the anti-peeping display area S2 can be independently controlled to illuminate and deactivate, allowing the pixel arrangement structure to illuminate and deactivate only the regular display area S1, only the anti-peeping display area S2, or both the regular display area S1 and the anti-peeping display area S2. When the normal display area S1 and the anti-peeping display area S2 are lit at the same time, the display device is in a display state; when only the anti-peeping display area S2 is lit, the display device is in an anti-peeping state.

[0052] In some exemplary embodiments, as shown in FIG2 , the first repeating unit 1 may include a plurality of regular sub-pixels 3. The regular sub-pixels 3 may be a first regular sub-pixel 5, a second regular sub-pixel 6, and a third regular sub-pixel 7. The colors of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 are different. The color of the first regular sub-pixel 5 may be green, the color of the second regular sub-pixel 6 may be red, and the color of the third regular sub-pixel 7 may be blue. The number of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 may all be one, but are not limited thereto. The number may be greater than or equal to one. For example, there may be two first regular sub-pixels 5, one second regular sub-pixel 6, and one third regular sub-pixel 7. For another example, there may be one first regular sub-pixel 5, one second regular sub-pixel 6, and two third regular sub-pixels 7. As shown in FIG2 , the outer contours of the first, second, and third regular sub-pixels 5, 6, and 7 can all be rectangular, i.e., first rectangles, but are not limited thereto. The outer contours of the regular sub-pixels 3 can also all be circular, rhombus-shaped, or the like, or a portion of the regular sub-pixels 3 can be rectangular, while another portion can be other shapes. The outer contours of the first, second, and third regular sub-pixels 5, 6, and 7, i.e., the outer edges of the first rectangles, each have two long sides and two short sides. All long sides can extend in a first direction, and all short sides can extend in a second direction, but are not limited thereto. The directions in which the long sides extend may not be in the first direction. The long sides of the outer contours of the first, second, and third regular sub-pixels 5, 6, and 7 can be the same length. The short sides of the outer contours of the first and second regular sub-pixels 5 and 6 can be the same length. The short sides of the outer contours of the third regular sub-pixel 7 can be longer than the long sides of the first and second regular sub-pixels 5 and 6, but are not limited thereto. The lengths of the short and long sides of the first, second, and third regular sub-pixels 5, 6, and 7 are not subject to the above limitations. The first regular sub-pixel 5 and the second regular sub-pixel 6 can be spaced apart in the second direction, and the third regular sub-pixel 7 is set on one side of the first regular sub-pixel 5 and the second regular sub-pixel 6 and the first direction. The line connecting the centers of the first regular sub-pixel 5, the second regular sub-pixel 6 and the third regular sub-pixel 7 is a triangle, but not limited to this. The positions of the first regular sub-pixel 5, the second regular sub-pixel 6 and the third regular sub-pixel 7 can be randomly changed.

[0053] In some exemplary embodiments, as shown in Figures 2 and 3, the second repeating unit 2 may include a plurality of anti-peeping pixel groups 4, and the anti-peeping pixel group 4 may be a first anti-peeping pixel group 8, a second anti-peeping pixel group 9 and a third anti-peeping pixel group 10. The colors of the first anti-peeping pixel group 8, the second anti-peeping pixel group 9 and the third anti-peeping pixel group 10 may be different. The color of the first anti-peeping pixel group 8 may be red, the color of the second anti-peeping pixel group 9 may be green, and the color of the third anti-peeping pixel group 10 may be blue. The color of the second anti-peeping pixel group 9 may be the same as the color of the first regular sub-pixel 5, the color of the first anti-peeping pixel group 8 may be the same as the color of the second regular sub-pixel 6, and the color of the third anti-peeping pixel group 10 may be the same as the color of the third regular sub-pixel 7, but is not limited to this. The colors of the first anti-peeping pixel group 8, the second anti-peeping pixel group 9 and the third anti-peeping pixel group 10 may be interchanged. The number of the first privacy protection pixel group 8, the second privacy protection pixel group 9, and the third privacy protection pixel group 10 can all be one, but is not limited to this. The number can be greater than or equal to one. For example, there can be two first privacy protection pixel groups 8, one second privacy protection pixel group 9, and one third privacy protection pixel group 10. For another example, there can be one first privacy protection pixel group 8, one second privacy protection pixel group 9, and two third privacy protection pixel groups 10. The number of privacy protection pixel groups 4 in the second repeating unit 2 can be the same as the number of regular sub-pixels 3 in the first repeating unit 1. The number of first privacy protection pixel groups 8 is equal to the number of second regular sub-pixels 6, the number of second privacy protection pixel groups 9 is equal to the number of first regular sub-pixels 6, and the number of third privacy protection pixel groups 10 is equal to the number of third regular sub-pixels 7, but is not limited to this. The number of privacy protection pixel groups 4 in the second repeating unit 2 may not be equal to the number of regular sub-pixels 3 in the first repeating unit 1.

[0054] In some exemplary embodiments, as shown in Figures 2 and 3, each anti-peeping pixel group 4 in at least one second repeating unit 2 can be set to correspond to the regular sub-pixel 3 of the same color in two adjacent first repeating units 1, but this is not limited to this. The regular sub-pixels 3 and anti-peeping pixel groups 4 of the same color may not correspond to each other. In a second repeating unit 2, a first anti-peeping pixel group 8 can be close to the first repeating unit 1 on the upper side, and the first anti-peeping pixel group 8 can be correspondingly adjacent to the second regular sub-pixel 6 of the same color in the first repeating unit 1 on the upper side, that is, the first anti-peeping pixel group 8 and the regular sub-pixel 3 of the same color in the adjacent first repeating unit 1 are arranged correspondingly; a second anti-peeping pixel group 9 can be close to the first repeating unit 1 on the lower side, and the second anti-peeping pixel group 9 can be correspondingly adjacent to the first regular sub-pixel 5 of the same color in the first repeating unit 1 on the lower side, that is, the second anti-peeping pixel group 9 and the regular sub-pixel 3 of the same color in another adjacent first repeating unit 1 are arranged correspondingly; a third anti-peeping pixel group 10 can be close to the first repeating unit 1 on the lower side, and the third anti-peeping pixel group 10 can be correspondingly adjacent to the third regular sub-pixel 7 of the same color in the first repeating unit 1 on the lower side, that is, the third anti-peeping pixel group 10 and the third regular sub-pixel 7 of the same color in the adjacent first repeating unit 1 are arranged correspondingly. In a first repeating unit 1, the first regular sub-pixel 5 can be close to the second repeating unit 2 on the upper side, and the first regular sub-pixel 5 can be correspondingly adjacent to the second anti-peeping pixel group 9 of the same color in the second repeating unit 2 on the upper side, that is, the first regular sub-pixel 5 and the anti-peeping pixel group 4 of the same color in the adjacent second repeating unit 2 are arranged correspondingly; the second regular sub-pixel 6 can be close to the second repeating unit 2 on the lower side, and the second regular sub-pixel 6 can be correspondingly adjacent to the first anti-peeping pixel group 8 of the same color in the second repeating unit 2 on the lower side, that is, the second regular sub-pixel 6 and the anti-peeping pixel group 4 of the same color in another adjacent second repeating unit 2 are arranged correspondingly; the third regular sub-pixel 7 can be close to the second repeating unit 2 on the upper side, and the third regular sub-pixel 7 can be correspondingly adjacent to the third anti-peeping pixel group 10 of the same color in the second repeating unit 2 on the upper side, that is, the third regular sub-pixel 7 and the third anti-peeping pixel group 10 of the same color in the adjacent second repeating unit 2 are arranged correspondingly; each regular sub-pixel 3 in each first repeating unit 1 can find a corresponding anti-peeping pixel group 4 of the same color in two adjacent first repeating units 1. It can be seen that the regular sub-pixels 3 and the anti-peeping pixel group 4 of the same color are close to each other, which is beneficial to circuit wiring, simplifies the structure, facilitates production, and reduces production costs.

[0055] In some exemplary embodiments, as shown in FIG8 , the positions of the multiple privacy protection pixel groups 4 in the second repeating unit 2 can be randomly arranged. In one second repeating unit 2, the first privacy protection pixel group 8 is located near the lower first repeating unit 1 and is adjacent to the first regular sub-pixel 5 of a different color. The second privacy protection pixel group 9 is located near the upper first repeating unit 1 and is adjacent to the second regular sub-pixel 6 of a different color. In another second repeating unit 2, the third privacy protection pixel group 10 is located near the upper first repeating unit 1 and is adjacent to the second regular sub-pixel 6 of a different color. The second privacy protection pixel group 9 is located near the lower first repeating unit 1 and is adjacent to the third regular sub-pixel 7 of a different color. It can be seen that the regular sub-pixels 3 and anti-peeping pixel groups 4 of the same color are not positioned close to each other, or the adjacent regular sub-pixels 3 and anti-peeping pixel groups 4 may be different colors, or the adjacent second repeating units 2 and first repeating units 1 may not have regular sub-pixels 3 and anti-peeping pixel groups 4 set in corresponding positions. The relative positions of the various anti-peeping pixel groups 4 are not limited to the positions in Figure 8 and can be arranged randomly.

[0056] In some exemplary embodiments, as shown in Figures 2 and 3, at least one anti-peeping pixel group 4 may include multiple anti-peeping sub-pixels 11, each of which is spaced apart. The anti-peeping pixel group 4 may include two anti-peeping sub-pixels 11, each of which may be spaced apart in the first direction. The first anti-peeping pixel group 8 may include two first anti-peeping sub-pixels 13, the second anti-peeping pixel group 9 may include two second anti-peeping sub-pixels 14, and the third anti-peeping pixel group 10 may include two third anti-peeping sub-pixels 15. The two first anti-peeping sub-pixels 13 may be spaced apart in the first direction, the two second anti-peeping sub-pixels 14 may be spaced apart in the first direction, and the two third anti-peeping sub-pixels 15 may be spaced apart in the first direction. Separating the anti-peeping pixel group 4 into two parts can ensure an aperture ratio and prevent an excessively long extension length in the first direction. The positions of the multiple anti-peeping sub-pixels 11 are not limited to being arranged sequentially along the first direction and may be randomly distributed without a regular pattern. The outer contours of the two anti-peeping sub-pixels 11 can be rectangles of the same size, that is, the second rectangle, but are not limited to this. For example, one of the outer contours of the two anti-peeping sub-pixels 11 can be a rectangle, and the other can be other shapes. For example, the outer contours of the two anti-peeping sub-pixels 11 can both be other shapes. For example, the outer contours of the two anti-peeping sub-pixels 11 can both be rectangles, but the sizes can be different.

[0057] In some exemplary embodiments, as shown in Figure 5, at least one anti-peeping pixel group 4 may be an inseparable anti-peeping sub-pixel 11, the first anti-peeping pixel group 8 may be a first anti-peeping sub-pixel 13, the second anti-peeping pixel group 9 may be a second anti-peeping sub-pixel 14, and the third anti-peeping pixel group 10 may be a third anti-peeping sub-pixel 15. The first anti-peeping sub-pixel 13, the second anti-peeping sub-pixel 14 and the third anti-peeping sub-pixel 15 are all rectangular, but are not limited to this. For example, the outer contour of the anti-peeping sub-pixel 11 may be other shapes, or part of the anti-peeping pixel group 4 may be rectangular, and another part of the anti-peeping pixel group 4 may be other shapes.

[0058] In some exemplary embodiments, as shown in FIG4 , the privacy protection pixel group 4 includes three privacy protection sub-pixels 11, which are spaced apart in a first direction. The first privacy protection pixel group 8 includes three first privacy protection sub-pixels 13, the second privacy protection pixel group 9 includes three second privacy protection sub-pixels 14, and the third privacy protection pixel group 10 includes three third privacy protection sub-pixels 15. The three first privacy protection sub-pixels 13 are spaced apart in the first direction, the three second privacy protection sub-pixels 14 are spaced apart in the first direction, and the three third privacy protection sub-pixels 15 are spaced apart in the first direction. The privacy protection pixel group 4 is divided into three sections. The positions of the three privacy protection sub-pixels 11 are not limited to being arranged sequentially along the first direction; they can be randomly distributed without a regular pattern, and the number of privacy protection sub-pixels 11 can be greater than three. The outer contours of the three anti-peeping sub-pixels 11 can be rectangles of the same size, but are not limited thereto. For example, one of the outer contours of the three anti-peeping sub-pixels 11 can be a rectangle, and the others can be other shapes. For another example, the outer contours of all three anti-peeping sub-pixels 11 can be other shapes. For another example, the outer contours of all three anti-peeping sub-pixels 11 can be rectangles, but the sizes can be different.

[0059] In some exemplary embodiments, as shown in FIG6 , each privacy protection pixel group 4 in at least one second repeating unit 2 may include two privacy protection sub-pixels 11, and each privacy protection pixel group 4 in at least one second repeating unit 2 may include one privacy protection sub-pixel 11, forming two types of second repeating units 2. The two types of second repeating units 2 may be arranged according to a certain pattern or randomly. For example, in FIG6 , in the second repeating unit 2 on the left, the first privacy protection pixel group 8 may include one first privacy protection sub-pixel 13, the second privacy protection pixel group 9 may include one second privacy protection sub-pixel 14, and the third privacy protection pixel group 10 may include one third privacy protection sub-pixel 15; in the second repeating unit 2 on the right, the first privacy protection pixel group 8 includes two first privacy protection sub-pixels 13, the second privacy protection pixel group 9 includes two second privacy protection sub-pixels 14, and the third privacy protection pixel group 10 includes two third privacy protection sub-pixels 15. But not limited to this, the pixel arrangement structure may include multiple second repeating units 2, and different types of second repeating units 2 are distinguished according to the number of anti-peeping sub-pixels 11 in the anti-peeping pixel group 4. Different types of second repeating units 2 can be arranged according to a certain rule or randomly.

[0060] In some exemplary embodiments, as shown in FIG7 , some privacy protection pixel groups 4 in the second repeating unit 2 may include two privacy protection sub-pixels 11, and some privacy protection pixel groups 4 may include one privacy protection sub-pixel 11. For example, in the second repeating unit 2, the first privacy protection pixel group 8 may include one first privacy protection sub-pixel 13, the second privacy protection pixel group 9 may include one second privacy protection sub-pixel 14, and the third privacy protection pixel group 10 may include two third privacy protection sub-pixels 15, resulting in different numbers of privacy protection sub-pixels 11 between different privacy protection pixel groups 4 in a second repeating unit 2. However, this is not limiting. For example, in a second repeating unit 2, the first privacy protection pixel group 8 may include two first privacy protection sub-pixels 13, the second privacy protection pixel group 9 may include one second privacy protection sub-pixel 14, and the third privacy protection pixel group 10 may include two third privacy protection sub-pixels 15. The number of first privacy protection sub-pixels 13, second privacy protection sub-pixels 14, and third privacy protection sub-pixels 15 is not limited.

[0061] In some exemplary embodiments, as shown in FIG1 , in the shared mode, all anti-peeping sub-pixels 11 and all regular sub-pixels 3 are illuminated, forming an S-stripe arrangement. A regular display area S1 can form a single horizontal line of display pixels with an adjacent anti-peeping display area S2. A single horizontal line of display pixels refers to a pixel combination consisting of multiple repeating pixel units arranged horizontally and in a straight line. Triangle T2 represents a white dot pixel structure, which is a line connecting the centers of multiple pixels in the repeating unit that constitutes a single horizontal line of display pixels. In the anti-peeping mode, all anti-peeping sub-pixels 11 are illuminated, all regular sub-pixels 3 are off, the anti-peeping display area S2 forms a single horizontal line of display pixels, and triangle T1 represents a white dot pixel structure.

[0062] In some exemplary embodiments, as shown in Figures 9 to 12, in this pixel arrangement structure, the regular display area S1 may be divided into a first repeating unit 1 as shown in Figure 11, and the anti-peeping display area S2 may be divided into a second repeating unit 2 as shown in Figure 12, but this is not limited to this. The first repeating unit 1 and the second repeating unit 2 may be combined in other combinations different from the above-described combination. The first repeating unit 1 may include a plurality of regular sub-pixels 3. The regular sub-pixels 3 may be a first regular sub-pixel 5, a second regular sub-pixel 6, and a third regular sub-pixel 7. The first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 may have different colors. The first regular sub-pixel 5 may be green, the second regular sub-pixel 6 may be red, and the third regular sub-pixel 7 may be blue. The number of first regular sub-pixels 5 may be two, and the number of second regular sub-pixels 6 and third regular sub-pixels 7 may both be one, but this is not limited to this. Any number greater than or equal to one is sufficient. As shown in FIG2 , the outer contours of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 can all be triangular, i.e., first triangles, but are not limited thereto. The outer contours of the regular sub-pixels 3 can also all be circular, rhombus, rectangular, etc., or the outer contours of some regular sub-pixels 3 can be triangular, while the outer contours of others can be other shapes. The outer contours of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 can all be right triangles. The outer contours of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 each include two right-angled sides and a hypotenuse. The hypotenuses in the outer contours of the second regular sub-pixel 6 and the third regular sub-pixel 7 can face one side of the second direction, and the hypotenuses in the outer contours of the two first regular sub-pixels 5 can both face the other side of the second direction, but are not limited thereto. The orientations of the hypotenuses in the outer contours of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 can be random and unrestricted. The two first regular sub-pixels 5 may be of the same size, and the sizes of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 may be different, but are not limited thereto. For example, two of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 may be the same. The two first regular sub-pixels 5 may be spaced apart in the first direction, and the second regular sub-pixel 6 and the third regular sub-pixel 7 may be spaced apart in the first direction, but are not limited thereto. The positions of the first regular sub-pixel 5, the second regular sub-pixel 6, and the third regular sub-pixel 7 may be adjusted.

[0063] In some exemplary embodiments, as shown in Figures 9 to 12, the privacy protection pixel group 4 includes two privacy protection sub-pixels 11, which are arranged to be spaced apart in the first direction. The first privacy protection pixel group 8 includes two first privacy protection sub-pixels 13, the second privacy protection pixel group 9 includes two second privacy protection sub-pixels 14, and the third privacy protection pixel group 10 includes two third privacy protection sub-pixels 15. The two first privacy protection sub-pixels 13 are spaced apart in the first direction, the two second privacy protection sub-pixels 14 are spaced apart in the first direction, and the two third privacy protection sub-pixels 15 are spaced apart in the first direction. The privacy protection pixel group 4 is divided into two parts to ensure the aperture ratio and avoid excessive extension in the first direction. The positions of the multiple privacy protection sub-pixels 11 are not limited to being arranged sequentially along the first direction and can be randomly distributed without a regular pattern. The outer contours of the two privacy sub-pixels 11 can be triangles of equal size, i.e., two second triangles of equal size, but are not limited thereto. For example, one of the outer contours of the two privacy sub-pixels 11 can be a triangle, and the other can be another shape. Another example is that the outer contours of both privacy sub-pixels 11 can be another shape. Another example is that the outer contours of both privacy sub-pixels 11 can be triangles, but of different sizes. As shown in FIG10 , the hypotenuses in the outer contours of the two privacy sub-pixels 11 can be arranged in opposite directions, and one of the right-angled edges in the outer contour of the privacy sub-pixel 11 can face the other privacy sub-pixel 11. The outer contours of both privacy sub-pixels 11 can have a right-angled edge facing the adjacent regular sub-pixel 3, and the hypotenuse of the outer contour of the regular sub-pixel 3 can face the adjacent privacy pixel group 4.

[0064] In some exemplary embodiments, as shown in FIG13 , a portion of the privacy protection pixel groups 4 may include two privacy protection sub-pixels 11, while another portion of the privacy protection pixel groups 4 may include a single, inseparable privacy protection sub-pixel 11. For example, a portion of the third privacy protection pixel group 10 may include two third privacy protection sub-pixels 15 spaced apart in the first direction, while another portion of the third privacy protection pixel group 10 may include a single, inseparable third privacy protection sub-pixel 15. However, this is not limiting. For example, if one or both of the first privacy protection pixel group 8 and the second privacy protection pixel group 9 have different numbers of privacy protection sub-pixels 11, the number of privacy protection sub-pixels 11 in each privacy protection pixel group 4 is not limited to one or two, and may be three or more.

[0065] In some exemplary embodiments, as shown in FIG9 , in the shared state, all anti-peeping sub-pixels 11 and all regular sub-pixels 3 are illuminated, forming a blue diamond-like arrangement. A regular display area S1 and an adjacent anti-peeping display area S2 form a single horizontal line of display pixels, with rectangle T2 representing a white dot pixel structure. In the anti-peeping state, all anti-peeping sub-pixels 11 are illuminated, all regular sub-pixels 3 are off, the anti-peeping display area S2 forms a single horizontal line of display pixels, and triangle T1 represents a white dot pixel structure.

[0066] In some exemplary embodiments, as shown in Figures 14 to 18, a display panel includes a substrate 19, a pixel definition layer 21, and a light shielding structure 20, and also includes the aforementioned pixel arrangement structure 18. The pixel definition layer 21 is disposed on the substrate 19 and has an opening area 22. The pixel arrangement structure 18 is disposed corresponding to the opening area 22. The light shielding structure 20 is disposed on the side of the pixel definition layer 21 facing away from the substrate 19. The pixel definition layer 21 can be made of a black material (PDL). The opening area 22 is a plurality of holes that penetrate the pixel definition layer 21. The anti-peeping sub-pixels 11 and the regular sub-pixels 3 are correspondingly arranged within the holes to form the pixel arrangement structure 18. Adjacent anti-peeping sub-pixels 11 and regular sub-pixels 3, as well as two adjacent anti-peeping sub-pixels 11 and two adjacent regular sub-pixels 3, are separated by the PDL. Between the pixel definition layer 21 and the light-shielding structure 20 lies a thin-film encapsulation layer (TFE layer) 23 and a first coating layer (On-Cell Touch layer) 24. The TFE layer 23 can employ a three-layer or multi-layer structure (e.g., inorganic / organic / inorganic) and can be 8 to 20 μm thick. The touch layer can consist of one or more layers of metal mesh. To reduce stray light, the metal traces are blackened underneath and then coated with a 2 to 5 μm thick coating.

[0067] In some exemplary embodiments, as shown in Figures 14 to 18, the shading structure 20 includes a first black matrix layer 25 and a second black matrix layer 30. The second black matrix layer 30 may be located on the side of the first black matrix layer 25 facing away from the pixel definition layer 21. The distance between the first black matrix layer 25 and the second black matrix layer 30 is greater than 0. Both the first black matrix layer 25 and the second black matrix layer 30 can be made of a black light-shielding material (BM). The first black matrix layer 25 can have a first opening area 26, which includes a plurality of first openings 33. The number and dimensions of the first openings 33 are configured to match the anti-peeping sub-pixel 11 and the conventional sub-pixel 3. A filter layer 27 is installed in the first opening 33, and the filter layer 27 is made of a filter material (CF). The second black matrix layer 30 can have a second opening area 31 and a third opening area 32. The second opening area 31 includes second openings 34 extending in a transverse strip shape. The third opening area 32 includes a plurality of third openings 35. The second openings 34 are arranged corresponding to the conventional display area S1, so that light from the conventional sub-pixel 3 is not blocked by the second black matrix layer 30. The number and dimensions of the plurality of third openings 35 are configured to match the anti-peeping sub-pixel 11. The second black matrix layer 30 blocks light from the anti-peeping sub-pixel 11 to the left and right sides, thereby achieving an anti-peeping function. A second coating layer 28 and an organic layer 29 (IJP) may be provided between the first black matrix layer 25 and the second black matrix layer 30. The thickness of the second coating layer 28 may be 3 to 8 um, the thickness of the organic layer 29 may be 20 to 40 um, and the thickness of the first black matrix layer 25 and the second black matrix layer 30 may be 3 to 5 um.

[0068] In some exemplary embodiments, as shown in FIG19 , the display panel includes a light control film 36 having an LCF (Light Control Film) structure. The light control film 36 may extend from the pixel definition layer 21 to the second black matrix layer 30. The light control film 36 penetrates the structure between the pixel definition layer 21 and the second black matrix layer 30, and penetrates the first black matrix layer 25, the second coating layer 28, the organic layer 29, the first coating layer 24, and the like. The light control film 36 may be formed using a multiple-coating exposure method or an etching method. The light control film 36 may be disposed between two adjacent privacy sub-pixels 11, i.e., a light control film 36 may be disposed between two privacy sub-pixels 11 of the same color. This effectively controls light and enhances display quality. For example, a light control film 36 may be disposed between two second privacy sub-pixels 9 of the same green color. The position of the light control film 36 is not limited thereto. For example, some anti-peeping sub-pixels 11 of the same color may have the light control film 36 between them, while another part of the anti-peeping sub-pixels 11 of the same color may have the light control film 36 between them.

[0069] In some exemplary embodiments, a display device includes the above-mentioned display panel.
