Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel, display screen, electronic device, and display control method. Background Technology

[0002] With the rapid development of mobile terminal technology, the functions of portable electronic devices such as mobile phones have become increasingly rich, and they have been deeply integrated into people's daily lives and work scenarios, leading to a continuous increase in users' reliance on such electronic devices. In crowded places such as subways, buses, elevators, and queuing areas, when users use electronic devices, the personal information displayed on the screen can easily be spied on by those around them, leading to the risk of privacy leaks. Therefore, the need for screen information privacy protection for mobile terminals is becoming increasingly urgent.

[0003] Among related technologies, the mainstream solution is to attach an anti-peeping film to the surface of electronic device screens. This type of anti-peeping film is based on the principle of venetian blinds polarizing light. By blocking the light propagation path at a specific angle, it reduces the visible viewing angle of the screen, thereby preventing people in the vicinity from peeping at the screen information from the side, and thus achieving the purpose of protecting personal privacy and trade secrets.

[0004] However, privacy screen protectors have significant drawbacks, such as low light transmittance leading to degraded device power consumption, reduced display clarity affecting visual experience, excessive thickness interfering with fingerprint recognition, and poor fit when used with curved screens, which seriously affect the user experience. Summary of the Invention

[0005] This application provides a display panel, a display screen, an electronic device, and a display control method to solve the above problems.

[0006] Firstly, this application provides a display panel, including:

[0007] The display layer includes a plurality of first pixel units and a plurality of second pixel units, wherein the first pixel units and the second pixel units are arranged alternately along a target direction; wherein the target direction is the row direction or column direction of the display panel;

[0008] A light-shielding matrix layer is located on the light-emitting side of the display layer; wherein, the orthographic projection of the light-shielding matrix layer toward the display layer is located on the first part side of the first sub-pixel in the first pixel unit; the second sub-pixel of the second pixel unit is located on the second part side of the first sub-pixel; the first part side and the second part side overlap by at most one part.

[0009] Secondly, this application also provides a display screen, including the display panel as described above.

[0010] Thirdly, this application also provides an electronic device, including the display screen as described above.

[0011] Fourthly, this application also provides a display control method applied to a display panel, the display panel comprising: a display layer including a plurality of first pixel units and a plurality of second pixel units, the first pixel units and second pixel units being alternately arranged along a target direction; wherein the target direction is the row direction or column direction of the display panel; a light-shielding matrix layer located on the light-emitting side of the display layer; wherein the orthographic projection of the light-shielding matrix layer toward the display layer is located on a first portion side of a first sub-pixel in the first pixel unit; a second sub-pixel of the second pixel unit is located on a second portion side of the first sub-pixel; the first portion side and the second portion side overlap by at least one portion.

[0012] The method includes:

[0013] Control the first and second pixel units in the display panel to emit light, so as to operate in a first display state; or,

[0014] The first pixel unit is controlled to emit light so that it operates in the second display state.

[0015] The aforementioned display panel, display screen, electronic device, and display control method include a display panel comprising a display layer and a light-shielding matrix layer. The display layer includes multiple first pixel units and multiple second pixel units, which are alternately arranged along a target direction, which is either the row or column direction of the display panel. The light-shielding matrix layer is located on the light-emitting side of the display layer. The orthographic projection of the light-shielding matrix layer toward the display layer is located on the first portion side of the first sub-pixel in the first pixel unit, and the second sub-pixel of the second pixel unit is located on the second portion side of the first sub-pixel. Because the orthographic projection of the light-shielding matrix layer toward the display layer is located on the first portion side of the first sub-pixel, it can effectively block and absorb large-angle light emitted from the first portion side of the first sub-pixel, causing the large-angle light from the first portion side to attenuate rapidly, reducing the large-viewing-angle contrast of the first portion side, thereby achieving a partial privacy protection effect, suitable for privacy protection scenarios. Furthermore, since the second sub-pixel is located on the second part side of the first sub-pixel, and the first part side and the second part side overlap by at most, meaning that the orthographic projection of the light-shielding matrix layer toward the display layer is at least not located on the second part side, the distance between the light-shielding matrix layer and the second sub-pixel is relatively large. This reduces the influence of the light-shielding matrix layer on the large-angle light emitted by the second part side of the second sub-pixel, thereby improving the visibility of the second sub-pixel from a wide viewing angle. This, in turn, improves the display effect in display scenarios based on the second sub-pixel, such as non-peeping scenarios, and thus balances the privacy effect in privacy scenarios and the display effect in non-peeping scenarios.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0031] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the planar structure of the display panel 1000 in one embodiment of this application. Figure 2 This is a schematic diagram of the planar structure of the display panel 1000 in another embodiment of this application. Figure 3 This is a schematic diagram of the cross-sectional structure of a display panel 1000 provided in one embodiment of this application. Figures 1 to 3 As shown, the display panel 1000 includes a display layer 10 and a light-shielding matrix layer 20.

[0032] The display layer 10 includes a plurality of first pixel units 11 and a plurality of second pixel units 12. Each first pixel unit 11 may include a plurality of first sub-pixels 110, and each second pixel unit 12 may include a plurality of second sub-pixels 120. Each pixel unit may include a plurality of sub-pixel units arranged along a vertical target direction; that is, each first pixel unit 11 includes a plurality of first sub-pixel 110 units arranged along a vertical target direction, and each second pixel unit 12 includes a plurality of second sub-pixel 120 units arranged along a vertical target direction. Each sub-pixel unit may include a plurality of sub-pixels; that is, each first sub-pixel 110 unit may include a plurality of first sub-pixels 110, and each second sub-pixel 120 unit may include a plurality of second sub-pixels 120. The number of sub-pixels in each first sub-pixel unit and each second sub-pixel 120 unit is the same. For example, each first pixel unit 11 includes three first sub-pixels 110, and each second pixel unit 12 includes three second sub-pixels 120. The emission color of each sub-pixel in each sub-pixel unit is different. That is, the first sub-pixels 110 in the first sub-pixel unit 110 emit different colors, and the second sub-pixels 120 in the second sub-pixel unit 120 emit different colors. For example, each sub-pixel unit includes three sub-pixels, and the three sub-pixels emit red, blue, and green colors, that is, each sub-pixel unit includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Specifically, the first sub-pixel unit 110 includes a red first sub-pixel 111, a blue first sub-pixel 113, and a green first sub-pixel 112. The second sub-pixel unit 120 includes a red second sub-pixel 121, a blue second sub-pixel 123, and a green second sub-pixel 122. Each sub-pixel (first sub-pixel 110 and second sub-pixel 120) can include an Organic Light Emitting Diode (OLED) display device.

[0033] The first pixel unit 11 and the second pixel unit 12 are alternately arranged along the target direction. The target direction is the row or column direction of the display panel 1000. In this application, the display layer 10 may include a plurality of pixel modules 13 arranged along the target direction, each pixel module 13 including adjacent first pixel units 11 and second pixel units 12. In some embodiments, such as Figure 1 and Figure 2 As shown, the target direction is the column direction of the display panel 1000. The first pixel unit 11 and the second pixel unit 12 are arranged alternately along the column direction, that is, the first pixel unit 11 and the second pixel unit 12 each correspond to a pixel row. The sub-pixels in each pixel unit can be arranged sequentially along the row direction. In other embodiments, the target direction is the row direction of the display panel 1000. The first pixel unit 11 and the second pixel unit 12 are arranged alternately along the row direction, that is, the first pixel unit 11 and the second pixel unit 12 each correspond to a pixel column. The sub-pixels in each pixel unit can be arranged sequentially along the column direction.

[0034] The black matrix (BM) layer is located on the light-emitting side of the display layer 10. The black matrix layer 20 can be used to block and absorb reflected light and emitted light from wide viewing angles, thereby reducing the impact of reflected light on the image and reducing the light emitted from the display panel 1000 from wide viewing angles. The orthographic projection of the black matrix layer 20 toward the display layer 10 is located on the first portion side of the first sub-pixel 110 in the first pixel unit 11. The orthographic projection of the black matrix layer 20 toward the display layer 10 is not located on any of the remaining sides of the first sub-pixel 110 except for the first portion side. That is, the orthographic projection of the black matrix layer 20 toward the display layer 10 partially surrounds the first sub-pixel 110, rather than completely surrounding (or completely enclosing) the first sub-pixel 110. In other words, the orthographic projection of the black matrix layer 20 toward the display layer 10 is located around the first sub-pixel 110, and the orthographic projection forms a semi-enclosed structure around the first sub-pixel 110. Here, "semi-enclosed" does not strictly refer to 180° and can be broadly understood as any non-fully enclosed area.

[0035] In some embodiments, the light-shielding matrix layer 20 includes a plurality of light-shielding matrix structures 210. The plurality of light-shielding matrix structures 210 are arranged along a target direction. Each light-shielding matrix structure 210 is correspondingly disposed with respect to a first pixel unit 11. The orthographic projection of the light-shielding matrix structure 210 toward the display layer 10 is located on a first portion side of each first sub-pixel 110 in the corresponding first pixel unit 11. The orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is not located on the remaining side of each corresponding first sub-pixel 110. Further, the light-shielding matrix structure 210 may include a plurality of sub-light-shielding matrix structures 211, each sub-light-shielding matrix structure 211 being correspondingly disposed with respect to a first sub-pixel 110. The orthographic projection of the sub-light-shielding matrix structure 211 toward the display layer 10 is located on a first portion side of the corresponding first sub-pixel 110. The orthographic projection of the sub-light-shielding matrix structure 211 toward the display layer 10 is not located on the remaining side of the corresponding first sub-pixel 110. Among them, the sub-shading matrix structures 211 of the same shading matrix structure 210 can be arranged at intervals or continuously (i.e., integrated).

[0036] In some embodiments, the distance between the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 and the first sub-pixel 110 ranges from 0 to 6 μm. This distance range is determined by the minimum and maximum distances between the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 and the first sub-pixel 110 in a preset direction, where the preset direction refers to the direction perpendicular to the first portion side of the first sub-pixel 110. The light-shielding matrix layer 20 can extend along the first portion side away from the first sub-pixel 110, and its extension dimensions on different sides can be the same or different. In applications, the relative position between the light-shielding matrix layer 20 and the first sub-pixel 110 can be flexibly set to meet both privacy and display requirements.

[0037] The first sub-pixel 110 comprises multiple sides, and the first part of the sides refers to a portion of all the sides of the first sub-pixel 110. For example, if the first sub-pixel 110 comprises four sides, meaning the orthographic projection of the first sub-pixel 110 onto the light-shielding matrix layer 20 is a quadrilateral, then the first part of the sides may include one, two, or three sides of the first sub-pixel 110. As another example, if the first sub-pixel 110 comprises six sides, meaning the orthographic projection of the first sub-pixel 110 onto the light-shielding matrix layer 20 is a hexagon, then the first part of the sides may include one, two, three, four, or five sides of the first sub-pixel 110. It should be noted that this example only uses four or six sides of the first sub-pixel 110 as illustrations; other numbers are possible in actual applications, and no further limitations are imposed here.

[0038] The second sub-pixel 120 of the second pixel unit 12 is located on the second portion side of the first sub-pixel 110. The second portion side can be understood as the side of the first sub-pixel 110 in the target direction. In some embodiments, the target direction is the column direction, such as... Figure 1 As shown, the second part side is the side of the first sub-pixel 110 in the column direction, that is, the second sub-pixel 120 is located above and below the first sub-pixel 110. In other embodiments, the target direction is the row direction, then the second part side is the side of the first sub-pixel 110 in the row direction, that is, the second sub-pixel 120 is located to the left and right of the first sub-pixel 110.

[0039] The first part side is different from the second part side. The second part side overlaps with the first part side at most. That is, the second part side does not overlap with the first part side or partially overlaps. The remaining side of the first sub-pixel 110 includes at least the second part side. Specifically, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is at least not located on the second part side, or in other words, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is at least not located on the side of the first sub-pixel 110 in the target direction. For example, in Figure 1In the first sub-pixel 110, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the upper left and right sides of the first sub-pixel 110. The first part of the side includes the upper left and right sides, and the second part includes the upper and lower sides, meaning the first part and the second part partially overlap. For example, as... Figure 2 In the middle, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the left and right sides of the first sub-pixel 110, wherein the first part of the side includes the left and right sides, and the second part of the side is the top and bottom sides, that is, the first part of the side and the second part of the side do not overlap.

[0040] The display panel 1000 provided in this application embodiment, because the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the first part side of the first sub-pixel 110, can effectively block and absorb large-angle light emitted from the first part side of the first sub-pixel 110 through the light-shielding matrix layer 20, so that the large-angle light on the first part side can be rapidly attenuated, reducing the contrast of the first part side at a wide viewing angle, thereby achieving a partial privacy protection effect, suitable for privacy protection scenarios. For example, in Figure 1 In this design, a 270° privacy viewing angle is achieved. Furthermore, since the second sub-pixel 120 is located on the second part side of the first sub-pixel 110, and the second part side overlaps with the first part side at most, meaning that the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is at least not located on the second part side, the distance between the light-shielding matrix layer 20 and the second sub-pixel 120 is relatively large. This reduces the impact of the light-shielding matrix layer on the large-angle light emitted from the second part side of the second sub-pixel 120, thereby improving the visibility of the second sub-pixel 120 from a wide viewing angle. Consequently, this improves the display effect in display scenarios based on the second sub-pixel 120, such as non-privacy scenarios, thus balancing the privacy effect in privacy scenarios and the display effect in non-privacy scenarios.

[0041] Please continue reading. Figure 1 and Figure 2 In some embodiments, the second partial side is the side of the first sub-pixel 110 closest to the second sub-pixel 120. The first partial side includes at least one side of the first sub-pixel 110 away from the second sub-pixel 120. Alternatively, the first partial side includes at least one side other than the second partial side. The first sub-pixel 110 includes N sides, and the first partial side includes M sides, where 1 ≤ M ≤ N-1. This achieves 360°*M / N privacy protection and reduces the impact of the light-blocking matrix layer 20 on the visibility of the second sub-pixel 120, thereby improving the display viewing angle range of the second sub-pixel 120 and ultimately enhancing visibility in the second display state.

[0042] For example, such as Figure 1 and Figure 2As shown, the first sub-pixel 110 includes four sides, meaning the orthographic projection of the first sub-pixel 110 onto the display layer 10 is a quadrilateral. The first portion of the sides may include one, two, or three sides other than the second portion of the sides. Alternatively, the first sub-pixel 110 may include six sides, meaning the orthographic projection of the first sub-pixel 110 onto the display layer 10 is a hexagon. The first portion of the sides may include one, two, three, four, or five sides other than the second portion of the sides. In applications, the number of sides included in the first sub-pixel 110 can be other values, and the second portion of the sides can be flexibly set according to the specific structure of the sub-pixel and privacy requirements; no further limitations are imposed here.

[0043] Please continue reading. Figure 1 and Figure 2 In some embodiments, each sub-pixel (first sub-pixel 110 and second sub-pixel 120) includes a first side and a second side disposed opposite to each other along the target direction, and a third side and a fourth side disposed opposite to each other along the perpendicular target direction. The orthographic projection of each sub-pixel toward the display side is a quadrilateral. The second portion of the side is the first side. The first portion of the side includes at least one of the second, third, and fourth sides.

[0044] For example, the first part includes a second side, a third side, and a fourth side, that is, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the second side, the third side, and the fourth side of the first sub-pixel 110. For example, Figure 1 In this configuration, the first side is the bottom side, and the second, third, and fourth sides are the top, left, and right sides, respectively. This achieves 270° privacy protection from both above and below, and also reduces the impact of the light-blocking matrix layer 20 on the visibility of the second sub-pixel 120, thereby increasing the display viewing angle range of the second sub-pixel 120 and ultimately improving visibility in the second display state.

[0045] In another exemplary embodiment, the first part of the side includes a second side and a third side, that is, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the second and third sides of the first sub-pixel 110; or, the first part of the side includes a second side and a fourth side, that is, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the second and fourth sides of the first sub-pixel 110; or, the first part of the side includes a third side and a fourth side, that is, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the third and fourth sides of the first sub-pixel 110. For example, Figure 2 In the first part, the sides include the third and fourth sides, namely the left and right sides. In this way, 180° privacy protection on both sides can be achieved, and the impact of the light-blocking matrix layer 20 on the visibility of the second sub-pixel 120 can be reduced, thereby improving the display viewing angle range of the second sub-pixel 120 and thus improving the visibility in the second display state.

[0046] As another example, the first part of the side includes a second side, a third side, or a fourth side, that is, the orthogonal projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the second side, the third side, or the fourth side of the first sub-pixel 110. In this way, 90° privacy protection on one side can be achieved, and the impact of the light-shielding matrix layer 20 on the visibility of the second sub-pixel 120 can be reduced, thereby improving the display viewing angle range of the second sub-pixel 120 and thus improving the visibility in the second display state.

[0047] Please continue reading. Figures 1 to 3 In some embodiments, the first part of the side includes at least a first target side and a second target side. That is, the first target side and the second target side are different sides of the same first sub-pixel 110. The first relative distance is greater than or equal to the second relative distance. The first relative distance is the minimum distance between the light-shielding matrix layer 20 projected onto the first target side and the first sub-pixel 110, and the second relative distance is the distance between the light-shielding matrix layer 20 projected onto the second target side and the first sub-pixel 110. In other words, the minimum distance between the orthographic projections located on different sides of the first sub-pixel 110 and the first sub-pixel 110 can be the same or different.

[0048] For example, the first target side and the second target side are left and right sides that are set opposite to each other. That is, the orthographic projection of the light-shielding color matrix layer toward the display layer 10 is located on the left and right sides of the first sub-pixel 110. The minimum distance between the left orthographic projection and the first sub-pixel 110 can be greater than the minimum distance between the right orthographic projection and the first sub-pixel 110. In this way, by setting the relative distance between the light-shielding matrix layer 20 and the first sub-pixel 110 on different sides of the first sub-pixel 110, the difference in relative distance (i.e., the difference between the first relative distance and the second relative distance) can be flexibly set according to the color shift requirements, thereby improving the color shift problem and helping to balance the anti-peeping visual trajectory. In addition, the minimum distance between the left orthographic projection and the first sub-pixel 110 can also be the same as the minimum distance between the right orthographic projection and the first sub-pixel 110. In this way, by uniformly setting the relative distance between the light-shielding matrix layer 20 and the first sub-pixel 110 on different sides of the first sub-pixel 110, the uniformity of the display panel 1000 can be improved, thereby improving the display effect.

[0049] Please continue reading. Figure 3In some embodiments, the light-emitting area of ​​the first sub-pixel 110 is smaller than the light-emitting area of ​​the second sub-pixel 120. The light-emitting area refers to the physical area of ​​the portion that can actually emit visible light. The light-emitting area of ​​a sub-pixel is the physical area of ​​the portion of a single sub-pixel that can actually emit visible light. For example, when the sub-pixel is an OLED, the portion that emits visible light is the light-emitting functional layer, meaning the light-emitting area can be the physical area corresponding to the light-emitting functional layer. It is understood that the light-emitting area of ​​a sub-pixel directly affects its display viewing angle, and the two are positively correlated. The display viewing angle refers to the spatial angle range within which the light emitted by the sub-pixel can be perceived. Therefore, by differentiating the light-emitting areas of the first sub-pixel 110 and the second sub-pixel 120, with the light-emitting area of ​​the second sub-pixel 120 being larger than that of the first sub-pixel 110, the display viewing angle of the second sub-pixel 120 is made larger than that of the first sub-pixel 110. This reduces the display viewing angle under the display state based on the first sub-pixel 110, thereby improving the privacy protection effect, and increases the display viewing angle under the display state based on the second sub-pixel 120, thereby improving the display effect.

[0050] Furthermore, the light-emitting area of ​​the first sub-pixel 110 can be smaller than the light-emitting area of ​​the sub-pixel in the related technology, and the light-emitting area of ​​the second sub-pixel 120 can be larger than the light-emitting area of ​​the sub-pixel in the related technology. Thus, compared to the sub-pixels in the related technology, by reducing the light-emitting area of ​​the first sub-pixel 110 and increasing the light-emitting area of ​​the second sub-pixel 120, the difference in light-emitting areas between the first sub-pixel 110 and the second sub-pixel 120 is increased. This improves both the privacy protection effect and the normal display effect in non-privacy scenarios.

[0051] Furthermore, the light-emitting area of ​​the first sub-pixel 110 is smaller than the light-emitting area of ​​the second sub-pixel 120 of the same light-emitting color. For example, both the first pixel unit 11 and the second pixel unit 12 include a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Specifically, the light-emitting area of ​​the red first sub-pixel 111 is smaller than the light-emitting area of ​​the red second sub-pixel 121, the light-emitting area of ​​the blue first sub-pixel 113 is smaller than the light-emitting area of ​​the blue second sub-pixel 123, and the light-emitting area of ​​the green first sub-pixel 112 is smaller than the light-emitting area of ​​the green second sub-pixel 122. This reduces the viewing angle range in the display state based on the first sub-pixel 110, thereby improving the privacy protection effect, and increases the viewing angle range in the display state based on the second sub-pixel 120, thereby improving the display effect.

[0052] Please continue reading. Figure 1 and Figure 2In some embodiments, the light-emitting area of ​​the first sub-pixel 110 is equal to the light-emitting area of ​​the second sub-pixel 120. Further, the light-emitting area of ​​the first sub-pixel 110 is equal to the light-emitting area of ​​the second sub-pixel 120 of the same emitting color. In this way, each sub-pixel can be prepared with a uniform light-emitting area, simplifying the preparation process of each sub-pixel.

[0053] In some embodiments, the luminous areas of multiple sub-pixels within the same pixel unit are not entirely identical. Further, within the same pixel unit, the luminous areas of sub-pixels emitting different colors are different. Even further, within the same pixel unit, the luminous area of ​​a sub-pixel is positively correlated with the decay rate of its luminescent material. For example, the same pixel unit includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel, wherein the luminous area of ​​the blue sub-pixel is larger than that of the red sub-pixel, and the luminous area of ​​the red sub-pixel is larger than that of the green sub-pixel. Since the luminescent material of the blue sub-pixel needs to operate at high energy, its decay is the fastest, resulting in a shorter lifetime for the blue sub-pixel. Therefore, by increasing the luminous area of ​​the blue sub-pixel, i.e., increasing its aperture ratio, the required brightness can be achieved with a lower current density, thus slowing down the decay rate of the blue sub-pixel. Similarly, the light-emitting area of ​​the green sub-pixel can be set to the minimum, and the light-emitting area of ​​the red sub-pixel can be set between that of the blue and green sub-pixels. By differentiating the light-emitting area or aperture ratio of each sub-pixel, the lifespan of sub-pixels of different colors can be balanced, which can improve the color shift problem caused by the difference in lifespan and thus improve the display effect.

[0054] Furthermore, within the same pixel unit, subpixels of different emission colors have the same size in the target direction, but different sizes in at least one other direction. For example, in Figure 1 and Figure 2 In this design, each sub-pixel includes a first and a second side positioned opposite each other along the column direction, and a third and a fourth side positioned opposite each other along the row direction. The target direction is the column direction. Each sub-pixel has the same height in the column direction, but different widths in the row direction. Specifically, the blue sub-pixel is wider than the red sub-pixel, and the red sub-pixel is wider than the green sub-pixel. Thus, by differentiating the dimensions (such as width) of each sub-pixel in a certain direction, the luminous area of ​​sub-pixels of different luminous colors can be differentiated, thereby meeting lifespan and color deviation requirements.

[0055] Please continue reading. Figure 1 and Figure 2In some embodiments, the aperture ratio of the first pixel unit 11 is equal to the aperture ratio of the second pixel unit 12. The aperture ratio of the first pixel unit 11 refers to the total aperture ratio of all first sub-pixels 110 in the first pixel unit 11. The aperture ratio of the second pixel unit 12 refers to the total aperture ratio of all second sub-pixels 120 in the second pixel unit 12. The aperture ratio is the ratio of the light-emitting area to the total area. A pixel unit may include a light-emitting region and a non-light-emitting region. The light-emitting region refers to the physical region in the pixel that achieves effective light output; its boundary can be defined by the pixel aperture, the effective coverage area of ​​the functional layer, and the optical structure, and it is the physical carrier of the pixel's light-emitting area. The non-light-emitting region refers to the physical region in the pixel that does not participate in light output and can be used to set the pixel's peripheral structure, including but not limited to light-shielding matrices, driving circuits, signal lines, etc. The total area refers to the total physical area occupied on the display panel, including the light-emitting area corresponding to the light-emitting region and the non-light-emitting area corresponding to the non-light-emitting region. It can be understood that when the total pixel area is fixed, the larger the light-emitting area, the higher the aperture ratio; that is, the light-emitting area and the aperture ratio are positively correlated. Since the aperture ratio directly determines the luminous efficiency of a pixel unit, this application, by controlling the aperture ratios of the first pixel unit 11 and the second pixel unit 12 to be the same, can make the workload (such as current density and heat generation) of the first pixel unit 11 and the second pixel unit 12 more balanced, avoiding local overheating or accelerated aging of pixel units due to differences in aperture ratio, and extending the lifespan of the panel. Therefore, for screen lifespan, the brightness lifespan of the shared mode is greater than that of the privacy mode, typically 1.5 to 2 times. This minimizes the difference in lifespan between the two modes, making it less likely for the privacy mode pixels to age too quickly and cause screen burn-in, thus improving the overall lifespan. At the same time, the uniform structural design can also improve the performance stability of the panel under different environmental conditions (such as temperature and humidity), reducing fluctuations in display effects.

[0056] Please continue reading. Figure 3In some embodiments, the display layer 10 further includes a pixel definition layer 31 (PDL), which includes multiple first pixel openings and second pixel openings spaced apart from each other. A first sub-pixel 110 is located in a first pixel opening, and a second sub-pixel 120 is located in a second pixel opening. Thus, the shape and light-emitting area of ​​each sub-pixel can be defined by the pixel definition layer 31 to ensure that each sub-pixel functions correctly. Taking an OLED as an example, the pixel definition layer 31 may have multiple openings, each filled with a light-emitting material. The pixel definition layer 31 separates the light-emitting materials of sub-pixels with different light-emitting colors, thereby forming sub-pixels with different light-emitting colors. The shape of the openings in the pixel definition layer 31 can be, but is not limited to, any one of the following: circular, elliptical, square, rectangular, polygonal, or rhomboid. The light-shielding matrix layer 20 can be configured according to the shape of the pixel openings and privacy requirements.

[0057] Please continue reading. Figure 3 In some embodiments, the display viewing angle range of the first sub-pixel 110 is smaller than that of the second sub-pixel 120. In this application, "the display viewing angle range of the first sub-pixel 110 is smaller than that of the second sub-pixel 120" can mean that the display viewing angle range of the first sub-pixel 110 is a portion of the display viewing angle range of the second sub-pixel 120. Specifically, the display viewing angle within the display viewing angle range of each sub-pixel is the angle between the sub-pixel and the normal direction N (N1 or N2) of the pixel opening, and the display viewing angle within the display viewing angle range of each sub-pixel includes a 0° angle. That is, the display viewing angle range of the first sub-pixel 110 is the range including a 0° angle with the normal direction N1 of the first pixel opening, which is also the viewpoint range including the normal direction N1. The display viewing angle range of the second sub-pixel 120 is the range including a 0° angle with the normal direction N2 of the second pixel opening, which is also the viewpoint range including the normal direction N2. For example, Figure 3 In the first sub-pixel 110, the display viewing angle range includes a viewing angle a1 within an angle less than or equal to the normal N1, and the display viewing angle range of the second sub-pixel 120 includes a viewing angle a2 within an angle less than or equal to the normal N2. Because the light-blocking matrix layer 20 largely blocks and absorbs the wide-angle light emitted from the first sub-pixel 110, the display viewing angle range of the first sub-pixel 110 can be made smaller than that of the second sub-pixel 120. Therefore, as... Figure 3 As shown, the included angle a1 is less than the included angle a2, that is, a1 < a2.

[0058] The display viewing angle range of a subpixel refers to the spatial angle range within which the light emitted by the subpixel can be perceived. It is the visible viewing angle range that a viewer can see, specifically the viewing angle range when the viewer is looking directly at the display surface of the display panel 1000. When the viewer is directly in front of the display panel 1000, with their line of sight parallel to the normal direction, the user's viewing angle and display viewing angle are 0°, and the content displayed on the display panel 1000 can be clearly seen by the user. When the user looks at the display panel 1000 from the side, the user's viewing angle is the angle between the user's line of sight to the subpixel position and its normal. When the user's viewing angle is outside the display viewing angle range of the subpixel, the user's eyes cannot receive the emitted light from that subpixel, and therefore the user cannot see the displayed content at the corresponding subpixel position. Therefore, by limiting the display viewing angle of the first sub-pixel 110 to a smaller extent, and by controlling the first sub-pixel 110 to emit light only as needed, such as in a privacy scenario, that is, controlling the first pixel unit 11 to emit light while the second pixel unit 12 does not emit light, it is possible to effectively ensure that the display content of the display panel 1000 cannot be viewed from an angle beyond a certain range from the side, thus effectively achieving privacy protection.

[0059] Please continue reading. Figure 1 and Figure 4 , Figure 1 This is a schematic diagram of the planar structure of the display panel 1000 provided in an embodiment of this application in a second display state. Figure 4 This is a schematic diagram of the planar structure of a display panel 1000 provided in an embodiment of this application in a first display state.

[0060] Combination Figure 1 and Figure 4 In some embodiments, the display panel 1000 includes a first display state and a second display state. For example, Figure 4 As shown, in the first display state, the first pixel unit 11 emits light, while the second pixel unit 12 does not emit light. In the second display state, at least the second pixel unit 12 emits light.

[0061] In the first display state, the first pixel unit 11 of the display panel 1000 emits light, while the second pixel unit 12 does not. Specifically, the wide-angle light emitted by the first sub-pixel 110 of the first pixel unit 11 is blocked and absorbed by the light-shielding matrix layer 20, resulting in brightness attenuation and reduced contrast at wide viewing angles, thus achieving a privacy protection effect. In applications, when privacy protection is required, the display panel 1000 can be controlled to operate in the first display state, or privacy display mode / privacy state.

[0062] In the second display state, at least the second pixel of the display panel 1000 is illuminated. That is, in the second display state, the second pixel unit 12 is illuminated while the first pixel unit 11 is not illuminated; specifically, all second sub-pixels 120 are illuminated while all first sub-pixels 110 are not illuminated. Alternatively, as... Figure 1 As shown, in the second display state, both the first pixel unit 11 and the second pixel unit 12 of the display panel 1000 emit light, that is, both the first sub-pixel 110 and the second sub-pixel 120 emit light. For ease of description, the state in which all sub-pixels emit light is referred to as the normal display state, or the shared mode / shared state. In scenarios where privacy protection is not required, the display panel 1000 can be controlled to operate in the second display state. In applications, the display panel 1000 can be switched between the first display state and the second display state as needed.

[0063] The viewing angle of the display panel 1000 in the first display state is smaller than that in the second display state. The viewing angle of the display panel 1000 refers to the maximum range of angles from the front of the display panel 1000 (reference 0° viewing angle) to a certain direction (up, down, left, or right) where the screen content can still be clearly and accurately seen (with no significant distortion in brightness, contrast, or color). It can be understood that the light-blocking matrix layer 20 can block and absorb large-angle light emitted by the first sub-pixel 110, thereby reducing the viewing angle of the display panel 1000 based on the first sub-pixel 110 operating in the first display state, thus achieving a privacy protection effect.

[0064] Please continue reading. Figure 1 , Figure 2 and Figure 4 In some embodiments, each pixel unit includes sub-pixel units arranged along a vertical target direction. Specifically, the first pixel unit 11 includes a plurality of first sub-pixel 110 units arranged along the vertical target direction. The second pixel unit 12 may include a plurality of second sub-pixel 120 units arranged along the vertical target direction. Each sub-pixel unit includes a plurality of sub-pixels arranged along a vertical target direction. Specifically, the first sub-pixel 110 unit may include a plurality of first sub-pixels 110 arranged along the vertical target direction, and the second sub-pixel 120 unit may include a plurality of second sub-pixels 120 arranged along the vertical target direction. For example, the first sub-pixel 110 unit may include three first sub-pixels 110 arranged along the vertical target direction, and the second sub-pixel 120 unit may include three second sub-pixels 120 arranged along the vertical target direction. The emission color of each sub-pixel in each sub-pixel unit may be different. For example, the emission color of each sub-pixel in each sub-pixel unit may include red, blue, and green, i.e., the three sub-pixels are respectively a red sub-pixel, a blue sub-pixel, and a green sub-pixel.

[0065] In this design, the first pixel size is the same as the second pixel size. The first pixel size is the dimension of the first sub-pixel 110 unit in the vertical target direction, and the second pixel size is the total dimension of adjacent first pixel units 11 and second pixel units 12 in the target direction. For example, Figure 1 In the diagram, the first pixel size is the width W of the first sub-pixel unit 110, which is the sum of the widths of the three sub-pixels w1 + w2 + w3, where w1, w2, and w3 represent the widths of the three sub-pixels in the first sub-pixel unit 110. The second pixel size is the sum of the heights of the first pixel unit 11 and the second pixel unit 12, i.e., H = h1 + h2, where H represents the second pixel size, h1 represents the height of the first pixel unit 11, and h2 represents the height of the second pixel unit 12. Therefore, W = w1 + w2 + w3 = H = h1 + h2.

[0066] For example, both the first pixel size and the second pixel size are Pitch*2, where Pitch represents the straight-line distance between the centers of two adjacent sub-pixels of the same color. That is, in the vertical target direction, the first pixel size is Pitch*2; and, in the target direction, the second pixel size is also Pitch*2. For example, Figure 1 In, W=w1+w2+w3=Pitch*2, H=h1+h2=Pitch*2.

[0067] The display panel 1000 provided in this embodiment ensures that the pixels of the display panel 1000 have a standard square structure by keeping the size of the first pixel and the size of the second pixel consistent. This avoids stretching and distortion of the image in the row and column directions, ensures accurate reproduction of the image proportions, and improves the consistency of visual perception. Furthermore, by designing the size of the first pixel and the size of the second pixel to be Pitch*2, the horizontal and vertical arrangement periods of the pixel array are perfectly matched. This not only optimizes the light emission uniformity of the sub-pixels and reduces color shift and brightness differences in different directions, but also simplifies the photolithography layout, light-shielding matrix design, and driving circuit layout process in the panel manufacturing process, reducing production yield losses caused by improper size adaptation.

[0068] Please continue reading. Figure 1 , Figure 2 and Figure 4In some embodiments, the display panel 1000 includes pixel modules 13 arranged along a target direction, wherein the pixel modules 13 are adjacent first pixel units 11 and second pixel units 12. The pixel modules 13 include alternating first and second repeating units arranged along a direction perpendicular to the target direction. For example, if the target direction is a column direction, the display panel 1000 includes pixel modules 13 arranged along the column direction, and the pixel modules 13 include first pixel units 11 and second pixel units 12 arranged along the column direction; or, the pixel modules 13 include two adjacent pixel rows. In another example, if the target direction is a row direction, the display panel 1000 includes pixel modules 13 arranged along the row direction, and the pixel modules 13 include second pixel units 12 and second pixel units 12 arranged along the row direction; or, the pixel modules 13 include two adjacent pixel columns.

[0069] The first repeating unit includes a first sub-pixel 110 and two adjacent second sub-pixels 120, and the second repeating unit includes two adjacent first sub-pixels 110 and one second sub-pixel 120. The first repeating unit may include one first sub-pixel 110 of the first sub-pixel 110 unit and two adjacent second sub-pixels 120 of the second sub-pixel 120 unit. The second repeating unit may include one second sub-pixel 120 of the two adjacent first sub-pixels 110 and the second sub-pixel 120 unit in the first repeating unit. The six sub-pixels in the adjacent first and second repeating units may be the six sub-pixels of the adjacent first sub-pixel 110 and second sub-pixel 120 units. Three sub-pixels in the first repeating unit can be fitted to form a virtual triangle S1. Three sub-pixels in the second repeating unit can be fitted to form another virtual triangle S2.

[0070] The three sub-pixels in each repeating unit emit different colors. Specifically, the three sub-pixels in the first repeating unit emit different colors. The three sub-pixels in the second repeating unit emit different colors. For example, the three sub-pixels in each repeating unit emit red, green, and blue colors. Specifically, the three sub-pixels in the first repeating unit emit red, green, and blue colors. The three sub-pixels in the second repeating unit emit red, green, and blue colors.

[0071] For example, Figure 1In the first pixel unit 11, the target direction is the column direction. The first pixel unit 11 includes multiple first sub-pixel units 110 arranged along the column direction, each including a red first sub-pixel 111, a green first sub-pixel 112, and a blue first sub-pixel 113 arranged sequentially along the column direction. The second pixel unit 12 includes multiple second sub-pixel units 120 arranged along the column direction, each including a blue second sub-pixel 123, a red second sub-pixel 121, and a green second sub-pixel 122 arranged sequentially along the column direction. The pixel module 13 consists of adjacent first pixel units 11 and second pixel units 12 arranged along the column direction. The pixel module 13 includes multiple first repeating units and multiple second repeating units arranged alternately along the row direction. The first repeating units include red first sub-pixels 111, green first sub-pixels 112, and blue second sub-pixels 123, while the second repeating units include blue first sub-pixels 113, red second sub-pixels 121, and green second sub-pixels 122.

[0072] The display panel 1000 provided in the above embodiment designs the first sub-pixel 110 and the second sub-pixel 120 as Real RGB, so that each sub-pixel is arranged in a regular rectangular grid in the row and column direction. This symmetrical structure helps to achieve a more uniform viewing angle performance, effectively avoids color shift or brightness unevenness at large viewing angles, and improves the uniformity of the display panel 1000.

[0073] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the planar structure of a display panel in related technologies. Figure 6 for Figure 5 A schematic diagram of the cross-sectional structure of the display panel. Combined with... Figure 5 and Figure 6 In the related display panel, the display layer includes Class A subpixels and Class B subpixels. The orthographic projection of the light-shielding matrix layer 20BM' onto the display layer completely surrounds the Class B subpixels, forming a closed structure. Therefore, the light-shielding matrix layer 20BM' blocks and absorbs light from all directions (360°) of the Class B subpixels. Furthermore, the light-shielding matrix layer 20BM' also blocks and absorbs light from the Class A subpixels to a significant extent, resulting in a large brightness attenuation (L-decay) at large viewing angles based on Class A subpixels. In shared-mode scenarios where both Class A and Class B subpixels are displayed, the visibility at large viewing angles is poor, leading to a poor display effect in the shared-mode. The minimum distance L2 between the orthographic projection of the light-shielding matrix layer BM' onto the display layer and the Class A subpixels is relatively close. The display viewing angle range of the Class A subpixels is a3, and the display viewing angle range of the Class B subpixels is a4. To achieve a better anti-spying effect, Figure 5 and Figure 6 The light-shielding matrix layer BM' in the design is relatively wide, typically greater than 6µm. Therefore, in its shared-state mode, the light-shielding matrix layer BM' around the B-type sub-pixels will block the large viewing angle of the shared-state pixels, causing a significant decrease in brightness at a large viewing angle after the shared-state pixels are normally illuminated. In privacy mode, only the B-type sub-pixels are illuminated, and the brightness at a 30° viewing angle is only 6% of that at a 0° viewing angle, achieving a 30° privacy effect. However, in the shared-state mode of this design, the brightness attenuation is significant, affecting the visibility at a large viewing angle in the shared-state mode.

[0074] In contrast, please refer back to this. Figure 1 and Figure 3 In this application, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is only located on the first part of the first sub-pixel 110, spanning 270° from top to bottom and left to right. The orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is not located on the lower side of the first sub-pixel 110. Therefore, compared to... Figure 5 and Figure 6 In the display panel of the related technology shown, the light-shielding matrix layer 20 of this application has less impact on the second sub-pixel 120, which is closer to the first sub-pixel 110. The minimum distance between the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 and the second sub-pixel 120 is L1. The light-emitting area of ​​the first sub-pixel 110 is smaller than that of the B-type sub-pixel, and the distance between the corresponding light-shielding matrix layers 20 on both sides is smaller. Therefore, the display viewing angle range a1 of the first sub-pixel 110 is smaller than that of the B-type sub-pixel, i.e., a1 < a3. The light-emitting area of ​​the second sub-pixel 120 is larger than that of the A-type sub-pixel, and the distance between the corresponding light-shielding matrix layers 20 on both sides is larger, i.e., L1 > L2. Therefore, the display viewing angle range a2 of the second sub-pixel 120 is larger than that of the A-type sub-pixel, i.e., a2 > a4. Therefore, this application, while achieving privacy protection, improves the problem of poor visibility at wide viewing angles in display scenarios based on the second sub-pixel 120, such as in the shared state, increases the display viewing angle range of the second sub-pixel 120, improves the wide viewing angle visibility of the display based on the second sub-pixel 120, and achieves a balance between privacy protection and shared state display effects.

[0075] like Figure 7 As shown, Figure 7 For this application ( Figure 1 The simulation curves of brightness attenuation as a function of angle for display panels in the structure shown below and related technologies are presented. Table 1 below shows the simulation data of brightness attenuation as a function of angle for display panels in this application and related technologies. Figure 7As shown in Table 1, this embodiment features a privacy screen with switchable viewing angles in the left, right, and top directions, improving upon the poor visibility in the shared-mode large-viewing-angle display of related technologies and achieving a balance between privacy protection and shared-mode display effects. Furthermore, it eliminates the need for new manufacturing processes, simplifying the process by optimizing the pixel arrangement and utilizing differentiated pixel arrangement opening sizes. In addition, it effectively improves privacy protection, achieving over 30° privacy in both left and right directions. It also balances the privacy protection mode effect with the normal lighting mode display effect, achieving a small viewing angle in privacy mode and a larger viewing angle in shared mode.

[0076] Table 1

[0077]

[0078] It is understood that the display resolution of the display panel 1000 provided in the above embodiments in the first display state (the first sub-pixel 110 emits light and the second sub-pixel 120 does not emit light) is reduced by half compared to the display resolution in the display state where all sub-pixels emit light. Therefore, under the same inventive concept, this application can further improve the problem of reduced display resolution through the display panel 1000 provided in the following embodiments.

[0079] Please see Figure 8 , Figure 8 This is a schematic diagram of the planar structure of another display panel 1000 provided in one embodiment of this application. (In conjunction with...) Figure 3 and Figure 8 In some embodiments, the first sub-pixel 110 includes a first sub-segment pixel 1101 and a second sub-segment pixel 1102 that are spaced apart from each other. It should be noted that the "segmentation" in this application is a conceptual division and does not represent an actual physical segmentation operation. That is, the "first sub-segment pixel 1101" and "second sub-segment pixel 1102" in this application refer to pixel structures that can emit light independently, and do not mean that a sub-pixel is physically segmented to obtain two sub-segment pixels.

[0080] The first sub-segment pixel 1101 includes a first anode 11001, a first light-emitting functional layer 11002, and a first cathode. In some embodiments, the first anode 11001, the first light-emitting functional layer 11002, and the first cathode are stacked sequentially along a plane perpendicular to the target direction. The first anode 11001 is located away from the light-shielding matrix layer 20 and can be used to receive a first driving signal. The first cathode is located close to the light-shielding matrix layer 20 and can be grounded. The first light-emitting functional layer 11002 can emit light under the driving force of the first anode 11001 and the first cathode. The material of the first light-emitting functional layer 11002 is related to the emission color of the first sub-segment pixel 1101.

[0081] The second sub-segment pixel 1102 includes a second anode 12001, a second light-emitting functional layer 12002, and a second cathode. In some embodiments, the second anode 12001, the second light-emitting functional layer 12002, and the second cathode are sequentially stacked along a plane perpendicular to the target direction. The second anode 12001 is located away from the light-shielding matrix layer 20 and can be used to receive a second driving signal. The second cathode is located close to the light-shielding matrix layer 20 and can be grounded. The second light-emitting functional layer 12002 can emit light under the driving force of the second anode 12001 and the second cathode. The material of the second light-emitting functional layer 12002 is related to the emission color of the second sub-segment pixel 1102.

[0082] The first anode 11001 and the second anode 12001 are mutually insulated, meaning they are independently controlled. The first light-emitting functional layer 11002 and the second light-emitting functional layer 12002 are made of the same material. Specifically, within the same first sub-pixel 110, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 emit the same color. For example, in a red first sub-pixel 111, both the first sub-segment pixel 1101 and the second sub-segment pixel 1102 emit red light; that is, the red first sub-pixel 111 includes a red first sub-segment pixel 1111 and a red second sub-segment pixel 1112. Similarly, in a green first sub-pixel 112, both the first sub-segment pixel 1101 and the second sub-segment pixel 1102 emit green light; that is, the green first sub-pixel 112 includes a green first sub-segment pixel 1121 and a green second sub-segment pixel 1122. The first sub-segment pixel 1101 and the second sub-segment pixel 1102 in the blue first sub-pixel 113 both emit blue light, that is, the blue first sub-pixel 113 includes a blue first sub-segment pixel 1131 and a blue second sub-segment pixel 1132. The first cathode and the second cathode are connected.

[0083] The display panel 1000 provided in this application embodiment can independently control the first anode 11001 and the second anode 12001 because the first anode 11001 and the second anode 12001 are insulated from each other. Therefore, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 can be controlled to emit light independently, thereby improving the display resolution (Pixel Per Inch, PPI) of the display panel 1000.

[0084] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the planar structure of another display panel 1000 provided in a second display state according to an embodiment of this application. Figure 9This is a schematic diagram of the planar structure of another display panel 1000 provided in an embodiment of this application in a first display state (third display state).

[0085] Furthermore, combined Figure 8 and Figure 9 In some embodiments, in a first display state, at least one sub-segment pixel of each first sub-pixel 110 in the first pixel unit 11 emits light, and the second pixel unit 12 does not emit light (i.e., the second sub-pixel 120 does not emit light). Exemplarily, the first display state includes a first sub-display state, a second sub-display state, and a third sub-display state. In the first sub-display state, the first sub-segment pixel 1101 emits light, and both the second sub-segment pixel 1102 and the second sub-pixel 120 do not emit light. In the second sub-display state, the second sub-segment pixel 1102 emits light, and both the first sub-segment pixel 1101 and the second sub-pixel 120 do not emit light. In the third sub-display state, both the first sub-segment pixel 1101 and the second sub-segment pixel 1102 emit light, and the second sub-pixel 120 does not emit light.

[0086] In this configuration, the light-emitting area of ​​the first sub-pixel 1101 is smaller than that of the first sub-pixel 110, and the light-emitting area of ​​the second sub-pixel 1102 is smaller than that of the first sub-pixel 110. Therefore, the display viewing angle range of the display panel 1000 in the first sub-display state is smaller than that in the third sub-display state, and the display viewing angle range of the display panel 1000 in the second sub-display state is smaller than that in the third sub-display state, and the display viewing angle range of the display panel 1000 in the third sub-display state is smaller than that in the aforementioned second display state.

[0087] In applications, in scenarios requiring privacy protection, the display panel 1000 can operate in a first sub-display state, a second sub-display state, or a third sub-pixel state, i.e., in privacy mode or privacy state. Furthermore, in scenarios requiring a higher level of privacy protection, the display panel 1000 can operate in either the first sub-segment pixel 1101 or the second sub-segment pixel 1102 by emitting light, further reducing the wide viewing angle visibility of the display panel 1000 and thus improving the privacy protection effect. In scenarios requiring privacy protection without sacrificing PPI, the display panel 1000 can operate in a third sub-display state by emitting light from the first sub-segment pixel 1101 and the second sub-segment pixel 1102. This achieves privacy protection without sacrificing display resolution; that is, the display resolution of the display panel 1000 in the third sub-display state is the same as described above. Figure 1The display panel 1000 shown has a comparable display resolution in the display state where all sub-pixels are illuminated. It improves the display resolution in privacy mode, greatly enhances visual clarity, and has little impact on lifespan.

[0088] Furthermore, in some embodiments, the aforementioned second display state includes a fourth sub-display state, a fifth sub-display state, and a sixth sub-display state. For example... Figure 8 As shown, in the fourth sub-display state, the first sub-segment pixel 1101, the second sub-segment pixel 1102, and the second sub-pixel 120 all emit light; in this state, the display panel 1000 has the highest display resolution, which is higher than that of the previous state. Figure 1 The display panel 1000, with all sub-pixels emitting light, achieves a 1.5-fold increase in brightness, further enhancing visual clarity and meeting the display requirements for high PPI. In the fifth sub-display state, the second sub-pixel 120 emits light, and one of the first sub-segment pixel 1101 and the second sub-segment pixel 1102 emits light while the other does not. In the sixth sub-display state, the second sub-pixel 120 emits light, while neither the first sub-segment pixel 1101 nor the second sub-segment pixel 1102 emits light. In this embodiment, by ensuring that at least the second sub-pixel 120 emits light, the display panel 1000 can operate in the fourth, fifth, or sixth sub-display states, satisfying different requirements for brightness, clarity, and wide viewing angle visibility, thus demonstrating strong applicability.

[0089] Please see Figure 8 and Figure 9 In some embodiments, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located at least on a first portion side of the first sub-segment pixel 1101 and a first portion side of the second sub-segment pixel 1102. For example, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on a first portion side of the first sub-segment pixel 1101 and a first portion side of the second sub-segment pixel 1102. The first portion side of the first sub-segment pixel 1101 refers to a portion of all sides of the first sub-segment pixel 1101. The first portion side of the second sub-segment pixel 1102 refers to a portion of all sides of the first sub-segment pixel 1101. Furthermore, the first portion side of the first sub-segment pixel 1101, the first portion side of the second sub-segment pixel 1102, and the first portion side of the first sub-pixel 110 are the same. The first portion side includes the upper left and right sides, meaning the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located at least on the upper left and right sides of the first sub-segment pixel 1101 and the upper left and right sides of the second sub-segment pixel 1102. Thus, the light-blocking matrix layer 20 can effectively block and absorb the wide-viewing-angle light of each sub-segmented pixel on the first part side, thereby achieving a privacy protection effect and improving display resolution, thereby improving display clarity.

[0090] Please see Figure 8 and Figure 9 Furthermore, in some embodiments, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is also located between the first sub-segment pixel 1101 and the second sub-segment pixel 1102. That is, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is also located between the first sub-segment pixel 1101 and the second sub-segment pixel 1102 within the same first sub-pixel 110. Specifically, the orthographic projection of the light-shielding matrix layer 20 toward the display layer 10 is located on the first portion side of the first sub-segment pixel 1101, the first portion side of the second sub-segment pixel 1102, and between the first sub-segment pixel 1101 and the second sub-segment pixel 1102. In this way, the light-shielding matrix layer 20 can not only effectively block and absorb the wide-viewing-angle light from each sub-segment pixel on the first portion side, but also effectively block and absorb the light between the first sub-segment pixel 1101 and the second sub-segment pixel 1102, so that the brightness of the light between the first sub-segment pixel 1101 and the second sub-segment pixel 1102 can be rapidly attenuated, further improving the privacy protection effect.

[0091] Please see Figure 8 and Figure 9 In some embodiments, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 are arranged along the target direction. For example, the target direction is a column direction, and the first pixel unit 11 and the second pixel unit 12 are arranged alternately in the column direction, wherein in each first sub-pixel 110 of the first pixel unit 11, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 are arranged along the column direction. In another example, the target direction is a row direction, and the first pixel unit 11 and the second pixel unit 12 are arranged alternately in the row direction, wherein in each first sub-pixel 110 of the first pixel unit 11, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 are arranged along the row direction.

[0092] In this embodiment, arranging the first sub-segment pixels 1101 and the second sub-segment pixels 1102 along the target direction can significantly improve the display resolution and brightness control accuracy in the target direction without changing the overall pixel arrangement, while optimizing color uniformity and dynamic display effects. Thus, the display resolution of the display panel 1000 in the target direction under the aforementioned third sub-display state (each sub-segment pixel emits light and the second sub-pixel 120 does not emit light) is comparable to... Figure 4 The display panel 1000 shown has the same display resolution in the first display state (the first sub-pixel 110 emits light and the second sub-pixel 120 does not emit light), so that the display panel 1000 does not sacrifice display resolution in privacy mode, improving clarity and uniformity of the display panel 1000.

[0093] In applications, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 can also be arranged in other directions. For example, the first sub-segment pixel 1101 and the second sub-segment pixel 1102 can be arranged in a direction perpendicular to the target direction. In this way, the display resolution of the display panel 1000 in the two sub-segment pixel arrangement directions can be improved, thereby improving the display resolution and meeting the requirements of high display resolution.

[0094] Please see Figure 8 and Figure 9 In some embodiments, the first pixel distance G1 is less than the second pixel distance G2, i.e., G1 < G2. The first pixel distance is the minimum pixel distance between the first sub-segment pixel 1101 and the second sub-segment pixel 1102, specifically the minimum pixel distance between the first sub-segment pixel 1101 and the second sub-segment pixel 1102 within the same first sub-pixel 110. The second pixel distance is the minimum pixel distance between two adjacent first sub-pixels 110. The second pixel distance can also be understood as the minimum pixel distance between two adjacent first sub-segment pixels 1101, or the minimum pixel distance between two adjacent second sub-segment pixels 1102. The range of the first pixel distance G1 can be 0~3μm, for example, it can be 1μm, 2μm, 3μm, or other values ​​within the range of 0~3μm. The range of the second pixel distance G2 can be 16~20μm, for example, it can be 16μm, 17μm, 18μm, 19μm, 20μm, or other values ​​within the range of 16~20μm. In this embodiment, by minimizing the minimum pixel distance between the first sub-segment pixel 1101 and the second sub-segment pixel 1102 as much as possible, the aperture ratio of the first sub-pixel 110 is guaranteed, thereby improving the display resolution without sacrificing the aperture ratio of the first sub-pixel 110, which helps to improve the uniformity of the display panel 1000.

[0095] Please see Figure 3 and Figure 8 In some embodiments, the first light-emitting functional layer 11002 and the second light-emitting functional layer 12002 are formed through the same mask opening. That is, in the same first sub-pixel 110, the first light-emitting functional layer 11002 of the first sub-segment pixel 1101 and the second light-emitting functional layer 12002 of the second sub-segment pixel 1102 are formed through the same mask opening. In other words, two sub-segment pixels of the same color in each first sub-pixel 110 correspond to the same mask opening. For example, two sub-segment pixels in the red first sub-pixel 111 share one mask opening, two sub-segment pixels in the blue first sub-pixel 113 share one mask opening, and two sub-segment pixels in the green first sub-pixel 112 share one mask opening.

[0096] A mask is a crucial tooling element used for pattern transfer in display panel manufacturing, such as the Fine Metal Mask (FMM) for OLEDs. A mask opening refers to a cutout area on the mask that allows material deposition; its size, shape, and position directly determine the final pattern of the light-emitting functional layer. For example, when each pixel is an OLED, the mask opening can be an FMM opening. The size of the mask opening is related to the light-emitting area, aperture ratio, and process precision of its corresponding first sub-pixel 110. It can be understood that the formation of the physical boundary of the pixel's light-emitting area is essentially the process of transferring the functional layer pattern through the mask opening during manufacturing. Taking OLED as an example, when using a fine metal mask for organic light-emitting layer evaporation, the FMM opening area allows organic material to be deposited onto the substrate, forming the light-emitting functional layer; the mask's blocking area prevents material deposition, corresponding to the non-light-emitting area of ​​the pixel. Therefore, the size of the FMM opening is directly equal to the effective size of the light-emitting layer; the larger the opening, the larger the light-emitting area, and the higher the aperture ratio, which is positively correlated with the light-emitting area. The mask opening sizes corresponding to the first sub-pixels 110 of different colors can be the same or different, depending on the display requirements.

[0097] Therefore, the first light-emitting functional layer 11002 of the first sub-segment pixel 1101 and the second light-emitting functional layer 12002 of the second sub-segment pixel 1102 can be fabricated simultaneously by sharing a single mask opening. This improves the display resolution while reducing the fabrication difficulty, eliminating the need for new process steps, and avoiding the problems of difficult manufacturing, low yield, and high cost caused by excessively high mask opening density in high-resolution panels.

[0098] Please see Figure 3 and Figure 8 In some embodiments, the display layer 10 further includes a pixel definition layer 31, which includes a plurality of mutually spaced first sub-pixel 110 openings, second sub-pixel 120 openings, and second pixel openings. Specifically, the first sub-segment pixel 1101 corresponds to the first sub-pixel 110 opening, the second sub-segment pixel 1102 corresponds to the second sub-pixel 120 opening, and the second sub-pixel 120 corresponds to the second pixel opening. For example, in the OLED display panel 1000, at least a portion of the first sub-segment pixel 1101's first light-emitting functional layer 11002 may be located at the first sub-pixel 110 opening, at least a portion of the second sub-segment pixel 1102's second light-emitting functional layer 12002 may be located at the second sub-pixel 120 opening, and at least a portion of the second sub-pixel 120's second light-emitting functional layer 12002 may be located at the second pixel opening.

[0099] Therefore, the shape and light-emitting area of ​​each pixel (first sub-segment pixel 1101, second sub-segment pixel 1102, and second sub-pixel 120) can be defined through the pixel definition layer 31 to ensure that each pixel can work correctly. In application, the pixel definition layer 31 can be prepared by a photoluminescence drying process to form the openings of the first sub-pixel 110, the second sub-pixel 120, and the second pixel. The second light-emitting functional layer 12002 of each first sub-pixel 110 is prepared by sharing a mask opening, thereby obtaining each pixel and providing technical support for improving display resolution. Due to the high precision of the exposure process, the range of the aforementioned first pixel distance G1 (i.e., the minimum distance between the first sub-segment pixel 1101 and the second sub-segment pixel 1102) can be reduced to 0~3μm, such as 1μm, ensuring the aperture ratio of the first sub-pixel 110. Thus, while improving display resolution, the aperture ratio of the first sub-pixel 110 is not sacrificed, which helps to improve the uniformity of the display panel 1000. Moreover, no new process is required; the display resolution can be improved simply by optimizing the pixel arrangement.

[0100] Please see Figure 8 In some embodiments, the light-emitting area of ​​the first sub-segment pixel 1101 is the same as the light-emitting area of ​​the second sub-segment pixel 1102. That is, the light-emitting area of ​​the first sub-segment pixel 1101 and the light-emitting area of ​​the second sub-segment pixel 1102 in the same first sub-pixel 110 are the same. In this way, by designing the first sub-segment pixel 1101 and the second sub-segment pixel 1102 to have the same light-emitting area, the display resolution can be improved while the uniformity of the display panel 1000 can also be enhanced.

[0101] Please see Figure 3 In some embodiments, the display panel 1000 further includes an insulating layer 32 located between the anodes of each pixel, which can achieve insulation between the pixels.

[0102] Please see Figure 3 In some embodiments, the display panel 1000 further includes a driving layer 33, which is disposed on the side of the display layer 10 away from the touch layer 35, and is used to drive the pixel units (including the first pixel unit 11 and the second pixel unit 12) of the display layer 10 to emit light, thereby enabling the display function.

[0103] Please see Figure 3In some embodiments, the driving layer 33 may include a TFT thin-film transistor array. The driving layer 33 is connected between the driving circuit and each pixel unit, and is used to apply the driving signal provided by the driving circuit to the corresponding pixel, thereby driving the pixel unit to emit light and display. The sub-pixels included in the pixel unit may be OLEDs. The cathode of the OLED is grounded, and the anode is connected to the driving layer 33. The driving layer 33 is used to control the application of the driving signal provided by the driving circuit to the anode of at least some of the sub-pixels in the corresponding pixel unit, thereby powering on at least some of the sub-pixels in the corresponding pixel unit and causing them to emit light.

[0104] Please see Figure 3 In some embodiments, the driving layer 33 is used to drive only the first sub-pixel 110 of the display layer 10 to emit light, so that the display panel 1000 operates in a first display state. This achieves a privacy protection effect and is suitable for privacy scenarios.

[0105] Furthermore, in some embodiments, the driving layer 33 can also be used to drive only the first sub-segment pixel 1101 of the display layer 10 to emit light, so that the display panel 1000 operates in a first sub-display state. Alternatively, the driving layer 33 can also be used to drive only the second sub-segment pixel 1102 of the display layer 10 to emit light, so that the display panel 1000 operates in a second sub-display state. Alternatively, the driving layer 33 can also be used to drive only the first sub-segment pixel 1101 and the second sub-segment pixel 1102 of the display layer 10 to emit light, so that the display panel 1000 operates in a third sub-display state. In this way, while achieving privacy protection, the display resolution can also be improved, thereby enhancing clarity.

[0106] Please see Figure 3 In some embodiments, the driving layer 33 is used to drive at least the second sub-pixel 120 unit of the display layer 10 to emit light, so that the display panel 1000 operates in a second display state. This improves the display effect and is applicable to non-peeping scenarios or normal display scenarios.

[0107] In some embodiments, the driving layer 33 may also include structural layers such as a planarization layer and a buffer layer 36, which will not be described in detail here.

[0108] Please see Figure 3 In some embodiments, the display panel 1000 further includes a base layer 34, which is disposed on the side of the driving layer 33 opposite to the display layer 10. The base layer 34 serves as the base of the display panel 1000 and carries the other layers of the display panel 1000.

[0109] Please see Figure 3In some embodiments, the display panel 1000 further includes a touch layer 35. The touch layer 35 is located between the display layer 10 and the light-shielding matrix layer 20. The touch layer 35 may be disposed on the side of the display layer 10 closer to the light-shielding matrix layer 20, and the light-shielding matrix layer 20 may be disposed on the side of the touch layer 35 away from the display layer 10. The touch layer 35 may include multiple rows and columns of metal traces, which intersect to form light-transmitting areas for light from each pixel to pass through. Thus, the display panel 1000 can achieve touch functionality through the touch layer 35, and can form light-transmitting areas for light from each pixel to pass through without affecting the pixel's light emission display.

[0110] Please see Figure 3 In some embodiments, the display panel 1000 further includes a buffer layer 36, which may be located in the area between the metal traces of the touch layer 35 to form a co-layer with the touch layer 35. This provides support for the insulation between the metal traces, ensuring touch functionality.

[0111] Please see Figure 3 In some embodiments, the display panel 1000 further includes an encapsulation layer 37 disposed between the display layer 10 and the touch layer 35. The encapsulation layer 37 is used to encapsulate the display layer 10 and to bond and fix the display layer 10 and the touch layer 35 together. The encapsulation layer 37 may be a thin film encapsulation (TFE) layer.

[0112] Please see Figure 3 In some embodiments, the display panel 1000 further includes a first optical adhesive layer 38. The first optical adhesive layer 38 may be located in the region between the light-shielding matrix structures 210 in the light-shielding matrix layer 20 to form an optical adhesive co-layer, and may also be located between the optical adhesive co-layer and the touch layer 35. The light-shielding matrix layer 20 can be fixedly connected to the touch layer 35 by bonding the first optical adhesive layer 38 to it. The material of the first optical adhesive layer 38 is a light-transmitting adhesive, thereby simultaneously achieving the light-shielding function of the light-shielding matrix and the optical adhesive bonding function.

[0113] Please see Figure 3 In some embodiments, the display panel 1000 further includes a polarizer (POL) layer 40 located on the side of the light-shielding matrix layer 20 away from the display layer 10.

[0114] Please see Figure 3In some embodiments, the display panel 1000 further includes a second optical adhesive layer 39, which is located between the polarizer layer 40 and the light-shielding matrix layer 20, and is used to bond and fix the polarizer layer 40 and the light-shielding matrix layer 20. The material of the second optical adhesive layer 39 is an adhesive with light-transmitting properties that allows light to pass through.

[0115] Please see Figure 3 In some embodiments, the display panel 1000 further includes a protective layer 41, which is located on the side of the polarizer layer 40 away from the light-shielding matrix layer 20. This protective layer 41 serves as the outermost layer of the display panel 1000 and provides protection. The protective layer 41 is made of a light-transmitting material, such as PET (polyethylene terephthalate).

[0116] Please see Figure 10 In some embodiments, a display screen 1200 is provided, which includes the display panel 1000 in any of the foregoing embodiments.

[0117] Please continue reading. Figure 10 In some embodiments, the display screen 1200 further includes a cover plate 1100. The cover plate 1100 is located on the light-emitting surface of the display panel 1000, i.e., one side of the display surface, and serves as a protective plate for the display screen 1200. The cover plate 1100 includes, but is not limited to, glass or plastic cover plates. The cover plate 1100 can serve as the outermost structural component of the display screen 1200 and is adhered to the display panel 1000, providing protection for the display panel 1000.
