Description

Display panel and display device Technical Field

[0001] This disclosure relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

[0002] With the wider application of display devices, the privacy of these devices is receiving increasing attention. Active-matrix organic light-emitting diode (AMOLED) is a display technology. AMOLED displays require privacy features (peep mode) in certain privacy scenarios, while also needing to share screen information in certain public scenarios (share mode). This necessitates that AMOLED displays have the ability to switch between privacy and share modes at any time.

[0003] However, currently, external privacy screen protectors are commonly used. When screen privacy needs to be protected, the privacy screen protector must be manually attached to the screen, and when screen privacy does not need to be protected, the privacy screen protector must be manually removed, which is inconvenient.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

Detailed Implementation

[0113] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0114] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0115] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0116] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0117] This disclosure provides a display panel, as shown in Figures 1-36. The display panel may include a light-emitting layer 3 and a light-shielding layer group 6. The light-emitting layer 3 may include a plurality of pixel regions 3a, each pixel region 3a including a shared pixel region 3aX and a privacy pixel region 3aF. A shared sub-pixel 35X is disposed within the shared pixel region 3aX, and a privacy sub-pixel 35F is disposed within the privacy pixel region 3aF. The light-shielding layer group 6 is disposed on the light-emitting side of the light-emitting layer 3. The orthographic projection of the light-shielding layer group 6 onto the light-emitting layer 3 overlaps at least with the privacy pixel region 3aF. The light-shielding layer group 6 is provided with a first opening 6a. The orthographic projection of the first opening 6a onto the light-emitting layer 3 overlaps at least with the privacy pixel region 3aF. The light-shielding layer group 6 is provided with a first opening 6a. The shadow and the privacy sub-pixel 35F at least partially overlap; wherein, the shared sub-pixel 35X may include a first shared sub-pixel 35XR, a second shared sub-pixel 35XG, and a third shared sub-pixel 35XB; the privacy sub-pixel 35F may include a first privacy sub-pixel 35FR, a second privacy sub-pixel 35FG, and a third privacy sub-pixel 35FB; the color of the first shared sub-pixel 35XR is the same as the color of the first privacy sub-pixel 35FR, the color of the second shared sub-pixel 35XG is the same as the color of the first privacy sub-pixel 35FR, and the color of the third shared sub-pixel 35XB is the same as the color of the third privacy sub-pixel 35FB.

[0118] The display panel disclosed herein can block light emitted from the privacy sub-pixel 35F at a large tilt angle through the light-shielding layer group 6, thereby reducing the viewing angle; while the light-shielding layer group 6 does not block or blocks light emitted from the shared sub-pixel 35X at a large tilt angle, thus having a smaller impact on the viewing angle; thus, the display panel can achieve privacy function when displaying through the privacy sub-pixel 35F, and achieve shared function when displaying through the shared sub-pixel 35X or when displaying through both the shared sub-pixel 35X and the privacy sub-pixel 35F, allowing for easy switching of display effects and convenient use.

[0119] The display panel can be an OLED (Organic Electroluminescence Display) panel, a QLED (Quantum Dot Light Emitting Diodes) panel, etc.; the display panel has a light-emitting side and a non-light-emitting side, which are arranged opposite to each other. The image can be displayed on the light-emitting side, and the side that displays the image is the display surface.

[0120] In this exemplary embodiment, referring to FIG1, the display panel may include a substrate 1, a driving layer 2, a light-emitting layer 3, an encapsulation layer group 4, and a touch layer group 5. The driving layer 2 can drive the light-emitting layer 3 to emit light. The driving layer 2 is disposed on one side of the substrate 1, and the light-emitting layer 3 is disposed on the side of the driving layer 2 opposite to the substrate 1. The driving layer 2 may include multiple driving circuits arranged in an array, and the light-emitting layer 3 may include multiple light-emitting devices arranged in an array. The driving circuits can drive the light-emitting devices to emit light. An encapsulation layer group 4 is disposed on the side of the light-emitting layer 3 opposite to the substrate 1.

[0121] In this exemplary embodiment, the material of the substrate 1 may include inorganic materials, such as glass, quartz, or metal. The material of the substrate 1 may also include organic materials, such as resins like polyimide, polycarbonate, polyacrylate, polyetherimide, polyethersulfone, polyethylene terephthalate, and polyethylene naphthalate. The substrate 1 may be formed from multiple material layers; for example, the substrate 1 may include multiple substrate layers, and the substrate layers may be made of any of the materials described above. Of course, the substrate 1 may also be a single layer, and may be any of the materials described above.

[0122] Specifically, referring to Figure 1, a shielding layer 21 can be provided on one side of the substrate 1. Light rays entering the active layer from the substrate 1 will generate photogenerated carriers in the active layer, which will have a significant impact on the characteristics of the thin-film transistor and ultimately affect the display quality of the display device. The shielding layer 21 can block the light rays entering from the substrate 1, thereby avoiding the impact on the characteristics of the thin-film transistor and the display quality of the display device. Depending on the type of thin-film transistor, the shielding layer 21 can be omitted.

[0123] A buffer layer 22 can also be formed on the side of the shielding layer 21 facing away from the substrate 1. The buffer layer 22 serves to block moisture and impurity ions in the substrate 1 (especially organic materials) and to increase hydrogen ions for the subsequently formed active layer. The buffer layer 22 is made of an insulating material to insulate the shielding layer 21 from the active layer. The buffer layer 22 may include silicon nitride, silicon oxide, or silicon oxynitride. Depending on the type of substrate 1 or the process conditions, the buffer layer 22 may be omitted.

[0124] An active layer is provided on the side of the buffer layer 22 facing away from the substrate 1. The active layer may include a channel portion 231 and conductor portions disposed at both ends of the channel portion 231. One of the two conductor portions is a source connection portion 232, and the other is a drain connection portion 233. A gate insulating layer 24 is provided on the side of the active layer facing away from the substrate 1. A gate layer 25 is provided on the side of the gate insulating layer 24 facing away from the substrate 1. The gate layer 25 may include a gate 251 and a gate line (not shown in the figure).

[0125] An interlayer dielectric layer 26 is provided on the side of the gate layer 25 facing away from the substrate 1. A via is provided on the interlayer dielectric layer 26, and the via connects to the source connection portion 232 and the drain connection portion 233. A first connection conductor layer 27 is provided on the side of the interlayer dielectric layer 26 facing away from the substrate 1. The first connection conductor layer 27 may include a source 271, a drain 272 and a data line (not shown in the figure). The data line may be connected to the source 271, or a part of the data line may be used as the source 271. The source 271 is connected to the source connection portion 232 through the via on the interlayer dielectric layer 26, and the drain 272 is connected to the drain connection portion 233 through the via on the interlayer dielectric layer 26.

[0126] In some other exemplary embodiments of this disclosure, a passivation layer is provided on the side of the first connection conductor layer 27 facing away from the substrate 1, and a via is also provided on the passivation layer; a second connection conductor layer is provided on the side of the passivation layer facing away from the substrate 1, and the second connection conductor layer may include a second source and / or a second drain, and the second source and the second drain are respectively connected to the source 271 and the drain 272 through the vias on the passivation layer. Of course, a third connection conductor layer, a fourth connection conductor layer, etc., may also be provided as needed.

[0127] Referring to Figure 1, a first planarization layer 28 is provided on the side of the first connecting conductor layer 27 facing away from the substrate 1. A via is provided on the first planarization layer 28, and the via is connected to the drain 272. The channel portion 231, the gate 251, the source 271, and the drain 272 form a thin-film transistor.

[0128] It should be noted that the thin-film transistor described in this specification is a top-gate thin-film transistor. In other exemplary embodiments of this disclosure, the thin-film transistor may also be a bottom-gate or dual-gate type, and its specific structure will not be described in detail here. Moreover, in cases where thin-film transistors with opposite polarities are used or where the current direction changes during circuit operation, the functions of "source 271" and "drain 272" are sometimes interchanged. Therefore, in this specification, "source 271" and "drain 272" can be interchanged.

[0129] The driving layer 2 may include a shared driving circuit 2a and a privacy driving circuit 2b. The shared driving circuit 2a includes at least two thin-film transistors and a capacitor. Only one thin-film transistor is shown in Figure 1 for illustration. The privacy driving circuit 2b also includes at least two thin-film transistors and a capacitor. Only one thin-film transistor is shown in Figure 1 for illustration. Its specific structure will not be described in detail here.

[0130] Please refer to Figure 1. A light-emitting layer 3 is provided on the side of the first planarization layer 28 that is away from the substrate 1. The light-emitting layer 3 may include a first electrode layer 31, a pixel definition layer 32, a light-emitting layer group 33, and a second electrode layer 34.

[0131] Specifically, a first electrode layer 31 is disposed on the side of the first planarization layer 28 facing away from the substrate 1. The first electrode layer 31 may include a shared electrode 311 and a privacy electrode 312 spaced apart. Moreover, within a pixel region 3a, the first electrode layer 31 may include three shared electrodes 311 and three privacy electrodes 312 spaced apart. The shared electrode 311 is electrically connected to the shared driving circuit 2a. Specifically, the shared electrode 311 is connected to the drain 272 of the switching thin-film transistor of the shared driving circuit 2a through a via. The privacy electrode 312 is electrically connected to the privacy driving circuit 2b. Specifically, the privacy electrode 312 is connected to the drain 272 of the switching thin-film transistor of the privacy driving circuit 2b through a via. The shared electrode 311 and the privacy electrode 312 may be anodes (pixel electrodes).

[0132] A pixel definition layer 32 is disposed on the side of the first electrode layer 31 facing away from the substrate 1. The pixel definition layer 32 has a shared opening 321 and a privacy opening 322. The shared opening 321 is connected to a shared electrode 311, ensuring that at least a portion of the shared electrode 311 is not covered by the pixel definition layer 32. The privacy opening 322 is connected to a privacy electrode 312, ensuring that at least a portion of the privacy electrode 312 is not covered by the pixel definition layer 32. The pixel definition layer 32 can be made of a black material capable of absorbing photons; for example, the pixel definition layer 32 can be made of black ink. The pixel definition layer 32 can absorb stray light, improving the display effect. Alternatively, the pixel definition layer 32 can also be made of a transparent material.

[0133] At least a portion of the light-emitting layer group 33 is located within the shared opening 321 and the privacy opening 322. For example, the light-emitting layer group 33 may be provided only within the shared opening 321 and the privacy opening 322, or the light-emitting layer group 33 may be provided not only within the shared opening 321 and the privacy opening 322, but also on the side of the pixel definition layer 32 facing away from the substrate 1.

[0134] A second electrode 34 is provided on the side of the light-emitting layer group 33 away from the substrate 1. The second electrode 34 can be a cathode (common electrode).

[0135] A shared sub-pixel 35X is formed by a group of light-emitting layers 33 within a shared opening 321, and a privacy sub-pixel 35F is formed by a group of light-emitting layers 33 within a privacy opening 322. The light-emitting layer 3 may include multiple pixel regions 3a, and each pixel region 3a may include a shared pixel region 3aX and a privacy pixel region 3aF. The shared sub-pixel 35X is disposed within the shared pixel region 3aX, and the privacy sub-pixel 35F is disposed within the privacy pixel region 3aF. This allows a single pixel region 3a to achieve both shared display and privacy display.

[0136] Within a pixel region 3a, the first electrode layer 31 may include three shared electrodes 311 and three privacy electrodes 312 spaced apart, such that first shared sub-pixels 35XR belonging to the same pixel region 3a share one shared electrode 311, allowing simultaneous control of all first shared sub-pixels 35XR within the same pixel region 3a; first privacy sub-pixels 35FR belonging to the same pixel region 3a share one privacy electrode 312, allowing simultaneous control of all first privacy sub-pixels 35FR within the same pixel region 3a. Second shared sub-pixels 35XG belonging to the same pixel region 3a share one shared electrode 311, allowing simultaneous control of all second shared sub-pixels 35XG within the same pixel region 3a; second privacy sub-pixels 35FG belonging to the same pixel region 3a share one privacy electrode 312, allowing simultaneous control of all second privacy sub-pixels 35FG within the same pixel region 3a. Third shared sub-pixels 35XB belonging to the same pixel area 3a share a common electrode 311, allowing simultaneous control of all third shared sub-pixels 35XB within the same pixel area 3a; similarly, third privacy sub-pixels 35FB belonging to the same pixel area 3a share a privacy electrode 312, allowing simultaneous control of all third privacy sub-pixels 35FB within the same pixel area 3a. This reduces the number of driving circuits required, which is beneficial for increasing pixel density; furthermore, it ensures the consistency of control over shared sub-pixels 35X and privacy sub-pixels 35F of the same color.

[0137] In some example implementations, within a sub-pixel region, for example, in the first region 3a1, the shared electrode 311 and the privacy electrode 312 are obtained by anodic cutting (where the cutting needs to be disconnected) of the same electrode, i.e., cutting a pixel (e.g., a red pixel) to obtain a shared sub-pixel 35X (e.g., the first shared sub-pixel 35XR in FIG. 18) and a privacy pixel. Then, each privacy pixel is further cut, here by providing at least two privacy openings 322 on the pixel definition layer 32, the at least two privacy openings 322 being connected to the same privacy electrode 312, and by using the light-shielding layer group 6 to cut the privacy pixel into at least two privacy sub-pixels 35F (e.g., the first privacy sub-pixel 35FR in FIG. 18), and the privacy electrode 312 does not need to be disconnected.

[0138] Furthermore, when there are at least two shared sub-pixels, the shared electrode 311 and the privacy electrode 312 are formed by anodizing, i.e., by cutting a pixel (e.g., a red pixel) to obtain the shared pixel and the privacy pixel. Then, each shared pixel is further cut by providing at least two shared openings 321 on the pixel definition layer 32, with each of the at least two shared openings 321 connected to the same shared electrode 311, thereby cutting the shared pixel to form at least two shared sub-pixels 35X (e.g., the first shared sub-pixel 35XR in FIG. 6), and the shared electrode 311 does not need to be disconnected.

[0139] Of course, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB can be set to one, so there is no need to further cut through the pixel definition layer 32.

[0140] The light-emitting layer group 33 may include a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer stacked sequentially. The hole injection layer is in contact with the first electrode, and the electron injection layer is in contact with the second electrode 34. Of course, in other exemplary embodiments of this disclosure, the light-emitting layer group 33 may only include a hole transport layer, a light-emitting layer, and an electron transport layer. The light-emitting layer group 33 may also have other structures, and its specific structure can be set as needed.

[0141] The display panel may also include an encapsulation layer group 4. An encapsulation layer group 4 is disposed on the side of the second electrode 34 facing away from the substrate 1. The encapsulation layer group 4 is used to encapsulate the display panel, preventing external moisture, impurities, etc., from entering the display panel and affecting its display effect. The encapsulation layer group 4 can be multi-layered, including organic and inorganic layers. Specifically, the encapsulation layer group 4 may include a first inorganic layer, an organic layer disposed on the side of the first inorganic layer facing away from the substrate 1, and a second inorganic layer disposed on the side of the organic layer facing away from the substrate 1. The materials of the first inorganic layer, organic layer, and second inorganic layer will not be described further here. Of course, the encapsulation layer group 4 may also include more or fewer layers.

[0142] The thickness of the encapsulation layer group 4 is greater than or equal to 6 μm and less than or equal to 20 μm. For example, the thickness of the encapsulation layer group 4 can be 6.5 μm, 7 μm, 7.5 μm, 8 μm, 8.5 μm, 9 μm, 9.5 μm, 10 μm, 10.5 μm, 11 μm, 11.5 μm, 12 μm, 12.5 μm, 13 μm, 13.5 μm, 14 μm, 14.5 μm, 15 μm, 15.5 μm, 16 μm, 16.5 μm, 17 μm, 17.5 μm, 18 μm, 18.5 μm, 19 μm, 19.5 μm, etc.

[0143] A light-shielding layer group 6 is provided on the light-emitting side of the light-emitting layer 3. The orthographic projection of the light-shielding layer group 6 on the light-emitting layer 3 overlaps at least with the privacy pixel area 3aF. For example, the orthographic projection of the light-shielding layer group 6 on the light-emitting layer 3 may only overlap with the privacy pixel area 3aF, but not with the shared pixel area 3aX. That is, the light-shielding layer group 6 is provided only in the privacy pixel area 3aF, and not in the shared pixel area 3aX. In this case, a first opening 6a is provided on the light-shielding layer group 6. The orthographic projection of the first opening 6a on the light-emitting layer 3 overlaps at least partially with the privacy sub-pixel 35F. For example, the edge line of the privacy sub-pixel 35F may coincide with the edge line of the orthographic projection of the first opening 6a on the light-emitting layer 3, or the orthographic projection of the first opening 6a on the light-emitting layer 3 may cover and be larger than the privacy sub-pixel 35F, so that the orthographic projection of the first opening 6a on the light-emitting layer 3 completely covers the privacy sub-pixel 35F.

[0144] Of course, in some other example embodiments of this disclosure, a portion of the privacy pixel 35F may overlap with a portion of the orthogonal projection of the first sub-opening 611 onto the light-emitting layer 3.

[0145] This design allows light emitted from the privacy sub-pixel 35F at a smaller angle to pass through the first opening 6a, while light emitted at a larger angle is blocked, thus reducing the viewing angle. The light-shielding layer group 6 does not block or only partially blocks light emitted from the shared sub-pixel 35X at a larger angle, thus having a smaller impact on the viewing angle. Consequently, the display panel achieves privacy protection when displaying through the privacy sub-pixel 35F and sharing functionality when displaying through the shared sub-pixel 35X, allowing for easy switching between display effects.

[0146] Of course, in some exemplary embodiments of this disclosure, the orthographic projection of the light-shielding layer group 6 on the light-emitting layer 3 may also overlap with the shared pixel region 3aX, that is, a light-shielding layer group 6 may also be provided in the shared pixel region 3aX. In this case, a second opening 6b is provided on the light-shielding layer group 6, and the orthographic projection of the second opening 6b on the light-emitting layer 3 at least partially overlaps with the shared sub-pixel 35X, so that light emitted from the shared sub-pixel 35X can be emitted through the second opening 6b. For example, the edge line of the shared sub-pixel 35X may coincide with the edge line of the orthographic projection of the second opening 6b on the light-emitting layer 3, or the orthographic projection of the second opening 6b on the light-emitting layer 3 may cover and be larger than the shared sub-pixel 35X, so that the orthographic projection of the second opening 6b on the light-emitting layer 3 completely covers the shared sub-pixel 35X.

[0147] Of course, in some other example embodiments of this disclosure, a portion of the shared sub-pixel 35X may overlap with a portion of the orthogonal projection of the second opening 6b onto the light-emitting layer 3.

[0148] Specifically, a first light-shielding layer 61 is provided on the side of the encapsulation layer group 4 facing away from the substrate 1. The material of the first light-shielding layer 61 can be a black light-shielding or light-absorbing material, such as black ink. The thickness of the first light-shielding layer 61 is greater than or equal to 1 μm and less than or equal to 3 μm, for example, the thickness of the first light-shielding layer 61 can be 1.5 μm, 2 μm, 2.5 μm, etc. The distance between the first light-shielding layer 61 and the light-emitting layer group 33 is greater than or equal to 6 μm and less than or equal to 12 μm, for example, the distance between the first light-shielding layer 61 and the light-emitting layer group 33 can be 6.5 μm, 7 μm, 7.5 μm, 8 μm, 8.5 μm, 9 μm, 9.5 μm, 10 μm, 10.5 μm, 11 μm, 11.5 μm, etc. Optionally, the distance between the first light-shielding layer 61 and the light-emitting layer group 33 is greater than or equal to 8 μm and less than or equal to 10 μm.

[0149] The first light-shielding layer 61 is provided with a first sub-opening 611 and a second sub-opening 612. The privacy pixel 35F is located within the orthographic projection of the first sub-opening 611 on the light-emitting layer 3. For example, the edge line of the privacy pixel 35F may coincide with the edge line of the orthographic projection of the first sub-opening 611 on the light-emitting layer 3, or the orthographic projection of the first sub-opening 611 on the light-emitting layer 3 may cover and be larger than the privacy pixel 35F, so that the orthographic projection of the first sub-opening 611 on the light-emitting layer 3 completely covers the privacy pixel 35F.

[0150] The shared sub-pixel 35X is located within the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3. For example, the edge line of the shared sub-pixel 35X may coincide with the edge line of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3, or the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 may cover and be larger than the shared sub-pixel 35X, such that the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 completely covers the shared sub-pixel 35X.

[0151] Furthermore, the distance between the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F is greater than or equal to 0 and less than or equal to 10 micrometers. For example, the distance between the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F can be 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc. Alternatively, the distance between the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F is greater than or equal to 0 and less than or equal to 6 micrometers.

[0152] The distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 is greater than or equal to 0 and less than or equal to 10 micrometers. For example, the distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 can be 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc. Alternatively, the distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 is greater than or equal to 0 and less than or equal to 6 micrometers.

[0153] In some embodiments, the distance between the edge of the privacy sub-pixel 35F and the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 is a first distance, and the distance between the edge of the shared sub-pixel 35X and the edge of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 is a second distance, the second distance being greater than the first distance; thereby the first light-shielding layer 61 blocks less light from the shared sub-pixel 35X to achieve shared display; while blocking more light from the privacy sub-pixel 35F to achieve privacy display, and after testing, when privacy display is enabled, the side viewing angle brightness attenuation (L Decay) ratio is reduced to less than 0.5% at a 30° viewing angle around the perimeter.

[0154] Of course, in some other exemplary embodiments of this disclosure, the second distance may be equal to the first distance. Alternatively, a portion of the privacy sub-pixel 35F may overlap with a portion of the orthogonal projection of the first sub-opening 611 onto the light-emitting layer 3, and a portion of the shared sub-pixel 35X may overlap with a portion of the orthogonal projection of the second sub-opening 612 onto the light-emitting layer 3.

[0155] Alternatively, the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 may be located within the privacy sub-pixel 35F, and the distance between the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F may be greater than or equal to 0 and less than or equal to 3 micrometers. The orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 may be located within the shared sub-pixel 35X, and the distance between the edge of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 and the edge of the shared sub-pixel 35X may be greater than or equal to 0 and less than or equal to 3 micrometers.

[0156] Alternatively, as shown in FIG1, the first light-shielding layer 61 may not be provided in the shared pixel area 3aX, but may be provided only in the privacy pixel area 3aF.

[0157] In some exemplary embodiments of this disclosure, referring to Figures 1-3, the display panel may further include a touch layer group 5. The touch layer group 5 is disposed on the side of the first light-shielding layer 61 facing away from the substrate 1. The touch layer group 5 enables the display panel to realize touch functionality. The touch layer group 5 may include at least one touch functional layer. For example, referring to Figures 2 and 3, the touch layer group 5 may include one touch functional layer. Referring to Figure 1, the touch layer group 5 may also include two touch functional layers. The material of the touch functional layers may be a conductive material, such as metal, conductive oxide, etc. The touch functional layer may be a single-layer structure or a two-layer or multi-layer structure. For example, the touch functional layer may be used as a second light-shielding layer 62.

[0158] Specifically, referring to FIG1, the touch layer group 5 may include a base layer 51, a first touch functional layer 52, a touch insulating layer 53, and a second touch functional layer 54. The base layer 51 is disposed on the side of the first light-shielding layer 61 away from the substrate 1, the first touch functional layer 52 is disposed on the side of the base layer 51 away from the substrate 1, the touch insulating layer 53 is disposed on the side of the first touch functional layer 52 away from the substrate 1, and the second touch functional layer 54 is disposed on the side of the touch insulating layer 53 away from the substrate 1. Both the first touch functional layer 52 and the second touch functional layer 54 are touch functional layers 56. The touch layer group 5 may also include a protective layer 55, which is disposed on the side of the second touch functional layer 54 away from the substrate 1, and the protective layer 55 can protect the second touch functional layer 54. In some embodiments, the first touch functional layer 52 and the second touch functional layer 54 together serve as the second light-shielding layer 62.

[0159] Of course, in some other example embodiments of this disclosure, one of the first touch function layer 52 and the second touch function layer 54 may also be used as the second light-shielding layer 62.

[0160] Referring to Figures 2 and 3, the touch layer group 5 may include a base layer 51, a touch functional layer 56, and a touch insulating layer 53 stacked sequentially. The touch functional layer 56 serves as a second light-shielding layer 62.

[0161] The second light-shielding layer 62 has a third sub-opening 621 and a fourth sub-opening 622, making the second light-shielding layer 62 a grid shape, that is, the second light-shielding layer 62 is a grid formed by grid lines. The width of the grid lines is greater than or equal to 3μm and less than or equal to 20μm. For example, the width of the grid lines can be 5μm, 8μm, 10μm, 12μm, 15μm, 17μm, etc.

[0162] The thickness of the touch functional layer 56 (second light-shielding layer 62) is greater than or equal to 0.1 μm and less than or equal to 3 μm. For example, the thickness of the touch functional layer 56 can be 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.5 μm, etc. The distance between the touch functional layer 56 and the light-emitting layer group 33 is greater than or equal to 10 μm and less than or equal to 30 μm. For example, the distance between the touch functional layer 56 and the light-emitting layer group 33 can be 13 μm, 15 μm, 17 μm, 20 μm, 23 μm, 25 μm, 28 μm, etc. Optionally, the distance between the touch functional layer 56 and the light-emitting layer group 33 can be greater than or equal to 12 μm and less than or equal to 20 μm.

[0163] The third sub-opening 621 is arranged opposite to the first sub-opening 611 to form the first opening 6a, and the fourth sub-opening 622 is arranged opposite to the second sub-opening 612 to form the second opening 6b; the orthographic projection of the first sub-opening 611 on the light-emitting layer 3 is located within the orthographic projection of the third sub-opening 621 on the light-emitting layer 3, and the orthographic projection of the second sub-opening 612 on the light-emitting layer 3 is located within the orthographic projection of the fourth sub-opening 622 on the light-emitting layer 3.

[0164] In some embodiments, the distance between the edge of the orthographic projection of the first sub-opening 611 onto the light-emitting layer 3 and the edge of the orthographic projection of the third sub-opening 621 onto the light-emitting layer 3 is a third distance, and the distance between the edge of the orthographic projection of the second sub-opening 612 onto the light-emitting layer 3 and the edge of the orthographic projection of the fourth sub-opening 622 onto the light-emitting layer 3 is a fourth distance. The fourth distance is greater than the third distance, so that the second light-shielding layer 62 blocks less light from the shared sub-pixel 35X to achieve shared display; while blocking more light from the privacy sub-pixel 35F to achieve privacy display.

[0165] In addition, in some other exemplary embodiments of this disclosure, the orthographic projection of the privacy pixel 35F and the third sub-opening 621 on the light-emitting layer 3 may overlap. For example, the edge line of the privacy pixel 35F may coincide with the edge line of the orthographic projection of the third sub-opening 621 on the light-emitting layer 3, or the orthographic projection of the third sub-opening 621 on the light-emitting layer 3 may cover and be larger than the privacy pixel 35F, so that the orthographic projection of the third sub-opening 621 on the light-emitting layer 3 completely covers the privacy pixel 35F.

[0166] The orthographic projections of the shared sub-pixel 35X and the fourth sub-aperture 622 onto the light-emitting layer 3 overlap; for example, the edge line of the shared sub-pixel 35X may coincide with the edge line of the orthographic projection of the fourth sub-aperture 622 onto the light-emitting layer 3, or the orthographic projection of the fourth sub-aperture 622 onto the light-emitting layer 3 may cover and be larger than the shared sub-pixel 35X, such that the orthographic projection of the fourth sub-aperture 622 onto the light-emitting layer 3 completely covers the shared sub-pixel 35X.

[0167] In some embodiments, the distance between the edge of the orthographic projection of the third sub-opening 621 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F is greater than or equal to 0 and less than or equal to 10 micrometers. For example, the distance between the edge of the orthographic projection of the third sub-opening 621 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F can be 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc. Alternatively, the distance between the edge of the orthographic projection of the third sub-opening 621 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F is greater than or equal to 0 and less than or equal to 8 micrometers.

[0168] The distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the fourth sub-opening 622 onto the light-emitting layer 3 is greater than or equal to 0 and less than or equal to 10 micrometers. For example, the distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the fourth sub-opening 622 onto the light-emitting layer 3 can be 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc. Alternatively, the distance between the edge line of the shared sub-pixel 35X and the edge line of the orthographic projection of the fourth sub-opening 622 onto the light-emitting layer 3 is greater than or equal to 0 and less than or equal to 8 micrometers.

[0169] Of course, in some other example embodiments of this disclosure, a portion of the privacy sub-pixel 35F may overlap with a portion of the orthogonal projection of the third sub-opening 621 onto the light-emitting layer 3, and a portion of the shared sub-pixel 35X may overlap with a portion of the orthogonal projection of the fourth sub-opening 622 onto the light-emitting layer 3.

[0170] Alternatively, the orthographic projection of the third sub-opening 621 onto the emissive layer 3 may be located within the privacy sub-pixel 35F, and the distance between the edge of the orthographic projection of the third sub-opening 621 onto the emissive layer 3 and the edge of the privacy sub-pixel 35F may be greater than or equal to 0 and less than or equal to 1 micrometer. The orthographic projection of the fourth sub-opening 622 onto the emissive layer 3 may be located within the shared sub-pixel 35X, and the distance between the edge of the orthographic projection of the fourth sub-opening 622 onto the emissive layer 3 and the edge of the shared sub-pixel 35X may be greater than or equal to 0 and less than or equal to 1 micrometer.

[0171] In this example embodiment, a protective layer 55 is provided on the side of the touch functional layer 56 facing away from the substrate 1. The material of the protective layer 55 may include SiOx (silicon oxide), SiNx (silicon nitride), OC (Organic Compound), etc. The protective layer 55 can be a single-layer structure or a multi-layer stacked structure. For example, the protective layer 55 can be OC, SiNx / OC / SiOx, SiNx / SiOx, or SiNx. The thickness of the protective layer 55 is greater than or equal to 0.1 μm and less than or equal to 5 μm. For example, the thickness of the protective layer 55 can be 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, etc. The protective layer 55 makes the base surface for forming the light adjustment layer 7 relatively flat, which is beneficial for the forming of the shared protrusion 71 and the privacy protrusion 72.

[0172] Of course, the touch layer group 5 can be omitted, and a second light-shielding layer 62 can be set separately. The second light-shielding layer 62 can be a single layer, or two or more layers. The two or more layers of the second light-shielding layer 62 can be spaced apart. For example, an insulating layer can be set between the two or more layers of the second light-shielding layer 62. Alternatively, when the touch layer group 5 is provided, the touch function layer 56 in the touch layer group 5 can not be used as a light-shielding layer, but can be set as a separate light-shielding layer. The light-shielding layer can be set on any side or both sides of the touch layer group 5, near or far from the substrate 1.

[0173] Referring to Figures 2 and 3, a light-adjusting layer 7 is provided on the side of the light-shielding layer group 6 away from the light-emitting layer 3. In this example embodiment, the light-adjusting layer 7 is provided on the side of the touch layer group 5 away from the substrate 1, such that the light-adjusting layer 7 is located on the light-emitting side of the light-emitting layer 3. The light-adjusting layer 7 may include a shared protrusion 71 and a privacy protrusion 72. At least a portion of the shared sub-pixel 35X and the orthographic projection of the shared protrusion 71 on the light-emitting layer 3 at least partially overlap. For a shared sub-pixel 35X and a shared protrusion 71, for example, the edge line of the orthographic projection of the shared protrusion 71 on the light-emitting layer 3 may coincide with the edge line of the shared sub-pixel 35X, or the orthographic projection of the shared protrusion 71 on the light-emitting layer 3 may cover and be larger than the shared sub-pixel 35X, such that the orthographic projection of the shared protrusion 71 on the light-emitting layer 3 completely covers the shared sub-pixel 35X. This arrangement ensures that most of the light emitted from the shared sub-pixel 35X can reach the shared protrusion 71.

[0174] In addition, a portion of the shared sub-pixel 35X and the shared protrusion 71 may not overlap on the orthogonal projection of the light-emitting layer 3.

[0175] At least a portion of the privacy sub-pixel 35F and the privacy protrusion 72 have their orthogonal projections on the light-emitting layer 3 at least partially overlapping. For a privacy sub-pixel 35F and a privacy protrusion 72, for example, the edge line of the orthogonal projection of the privacy protrusion 72 on the light-emitting layer 3 may coincide with the edge line of the privacy sub-pixel 35F, or the orthogonal projection of the privacy protrusion 72 on the light-emitting layer 3 may cover and be larger than the privacy sub-pixel 35F, so that the orthogonal projection of the privacy protrusion 72 on the light-emitting layer 3 completely covers the privacy sub-pixel 35F. This arrangement ensures that most of the light emitted from the privacy sub-pixel 35F can reach the privacy protrusion 72.

[0176] In addition, a portion of the privacy pixel 35F and the privacy protrusion 72 may not overlap on the orthogonal projection of the light-emitting layer 3.

[0177] Of course, in some other example embodiments of this disclosure, a portion of the orthographic projection of the shared protrusion 71 on the light-emitting layer 3 may overlap with a portion of the shared sub-pixel 35X, and a portion of the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3 may overlap with a portion of the privacy sub-pixel 35F.

[0178] A planarization layer 8 is provided on the side of the light-adjusting layer 7 facing away from the light-emitting layer 3. The refractive index of the planarization layer 8 is less than that of the light-adjusting layer 7. Specifically, the refractive index of the light-adjusting layer 7 is greater than or equal to 1.5 and less than or equal to 1.8. For example, the refractive index of the light-adjusting layer 7 can be 1.52, 1.55, 1.57, 1.6, 1.63, 1.65, 1.68, 1.7, 1.72, 1.75, 1.77, etc. The refractive index of the planarization layer 8 is greater than or equal to 1.4 and less than or equal to 1.6. For example, the refractive index of the planarization layer 8 can be 1.42, 1.45, 1.47, 1.5, 1.53, 1.55, 1.58, etc.

[0179] When light travels from the light adjustment layer 7 to the planarization layer 8, it travels from a denser medium to a less dense medium. Therefore, the light is refracted at the interface between the privacy protrusion 72 and the planarization layer 8. Moreover, the angle of incidence is smaller than the angle of refraction, changing the angle of the emitted light. This makes the emitted light more focused and allows it to exit from the front of the display panel, improving the light emission efficiency of the front of the display panel. According to experiments, compared to a structure without the privacy protrusion 72, the front brightness is increased by approximately 300% to 500%. The light emission efficiency of the sides of the display panel is reduced, increasing the privacy protection effect.

[0180] Similarly, light will be refracted at the interface between the shared protrusion 71 and the planarization layer 8. Moreover, the angle of incidence is smaller than the angle of refraction, which changes the angle of the emitted light, thereby making the emitted light more focused and emitted from the front of the display panel, improving the light emission efficiency of the front of the display panel. According to the experiment, compared with the structure without the shared protrusion 71, the brightness of the front is increased by about 300% to 500%.

[0181] In some embodiments, referring to Figures 2-5, the height of the privacy protrusion 72 is greater than the height of the shared protrusion 71 in the third direction Z. This arrangement makes the interface between the privacy protrusion 72 and the planarization layer 8 higher, allowing more light to be refracted through the privacy protrusion 72. This allows more light to change its emission angle, resulting in more light emanating from the front of the display panel, further improving the light emission efficiency of the front of the display panel, further reducing the light emission efficiency of the sides of the display panel, and further enhancing the privacy effect.

[0182] It should be noted that the first direction X and the second direction Y are parallel to the light-emitting layer 3, that is, the first direction X and the second direction Y are parallel to the side of the light-emitting layer 3 where the light-adjusting layer 7 is disposed, and the first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y are perpendicular; the third direction Z is perpendicular to the light-emitting layer 3, that is, the third direction Z is perpendicular to the side of the light-emitting layer 3 where the light-adjusting layer 7 is disposed.

[0183] In some exemplary embodiments of this disclosure, referring to Figures 16 and 17, a portion of the privacy sub-pixels 35F do not overlap with the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3; that is, a portion of the privacy sub-pixels 35F are not covered by the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3. This arrangement allows for a larger number of privacy sub-pixels 35F, increasing the pixel density of the privacy sub-pixels 35F.

[0184] In some embodiments, the area of ​​the privacy sub-pixel 35F is smaller than the area of ​​the shared sub-pixel 35X, and the projected area of ​​the privacy protrusion 72 on the light-emitting layer 3 is smaller than the projected area of ​​the shared protrusion 71 on the light-emitting layer 3.

[0185] Alternatively, in the third direction Z, the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 is greater than 1 and less than or equal to 10. For example, the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 can be 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, etc.

[0186] If the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 is too large, the height of the privacy protrusion 72 will be too high, increasing the difficulty of the manufacturing process.

[0187] If the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 is too small, the height of the privacy protrusion 72 will be too small, which will not be able to change more of the light emission angle, thus failing to effectively improve the light emission efficiency of the front of the display panel and thus failing to effectively increase the privacy effect.

[0188] The above-mentioned numerical range will not increase the difficulty of the process; on the contrary, it can change more of the light emission angles, effectively improve the light emission efficiency of the front of the display panel, and effectively increase the privacy protection effect.

[0189] Of course, in some other exemplary embodiments of this disclosure, the height of the privacy protrusion 72 may be the same as the height of the shared protrusion 71. Alternatively, the height of the privacy protrusion 72 may be less than the height of the shared protrusion 71. Specifically, the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 is greater than 0.1 and less than 1. For example, the ratio of the height of the privacy protrusion 72 to the height of the shared protrusion 71 may be 0.2, 0.4, 0.5, 0.6, 0.8, etc.

[0190] In some exemplary embodiments of this disclosure, referring to Figures 6-17, the shared sub-pixel 35X, which is obscured by the shared protrusion 71, is indicated by a dashed line, and the privacy sub-pixel 35F, which is obscured by the privacy protrusion 72, is indicated by a dashed line. The shared sub-pixel 35X can be configured as a strip extending along the first direction X, that is, the shared opening 321 can be configured as a strip extending along the first direction X, such that the shared sub-pixel 35X formed by the light-emitting layer group 33 within the shared opening 321 is configured as a strip extending along the first direction X; this configuration causes the shared sub-pixel 35X to have a second width and a second length, the second length being greater than the second width, and the second length being the dimension along the first direction X. In this case, the shared protrusion 71 can also be configured as a strip extending along the first direction X. That is, the orthogonal projection of the shared protrusion 71 on the light-emitting layer 3 can be configured as a strip extending along the first direction X. Specifically, referring to FIG5, the shared protrusion 71 can be configured as a semi-cylinder or less than a semi-cylinder extending along the first direction X, such that the shared protrusion 71 has a first width and a first length, the first length being greater than the first width, and the first length being the dimension along the first direction X. The first width of the shared protrusion 71 is greater than the second width of the shared sub-pixel 35X. Specifically, the ratio of the first width of the shared protrusion 71 to the second width of the shared sub-pixel 35X is greater than or equal to 2. For example, the ratio of the first width to the second width can be 2.1, 2.2, 2.3, 2.4, 2.5, etc.

[0191] This configuration ensures that light emitted from the shared sub-pixel 35X can reach the shared protrusion 71, and then be refracted by the shared protrusion 71 before exiting from the front of the display panel, thereby increasing the light emission efficiency of the front of the display panel.

[0192] It should be noted that the corners of the strip-shaped shared sub-pixels 35X can be set to right angles, obtuse angles, or acute angles. The corners of the strip-shaped shared sub-pixels 35X can also be chamfered, which can be rounded or beveled.

[0193] The privacy sub-pixel 35F can be set as a dot, that is, the privacy opening 322 can be set as a dot, so that the privacy sub-pixel 35F formed by the light-emitting layer group 33 within the privacy opening 322 can be set as a dot. For example, the privacy sub-pixel 35F can be set as a circle, ellipse, rounded square, rounded rectangle, square, rectangle, rhombus, polygon, etc. Referring to FIG4, the privacy protrusion 72 can also be set as a hemisphere or spherical cap; in this case, the diameter of the privacy protrusion 72 is larger than the diameter of the circumscribed circle of the privacy sub-pixel 35F. Specifically, the ratio of the diameter of the privacy protrusion 72 to the diameter of the circumscribed circle of the privacy sub-pixel 35F is greater than or equal to 2. For example, the ratio of the diameter of the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3 to the diameter of the circumscribed circle of the privacy sub-pixel 35F can be 2.1, 2.2, 2.3, 2.4, 2.5, etc.

[0194] Of course, in some other exemplary embodiments disclosed, the first opening 6a on the light-shielding layer group 6 may be configured as a dot, such that the privacy sub-pixel 35F defined by the first opening 6a may be configured as a dot. Similarly, the second opening 6b on the light-shielding layer group 6 may be configured as a dot, such that the shared sub-pixel 35X defined by the second opening 6b may be configured as a strip extending along the first direction X.

[0195] Setting the shared sub-pixel 35X as a strip and making the shared sub-pixels 35X in each pixel area 3a extend in the same direction can expand the field of view of the shared sub-pixels 35X in the extension direction (first direction X) and limit the field of view in the direction perpendicular to the extension direction of the shared sub-pixels 35X (second direction Y), so that the display panel can share display information in a directional manner and avoid information leakage in other directions of the display panel. Setting the privacy sub-pixel 35F as a dot can make the field of view of the display panel basically the same in all directions when the privacy display is in the privacy display state, that is, the privacy effect can be achieved in all directions, ensuring that the light emission effect between each pixel area 3a is relatively uniform, so that users within the light emission range of the privacy sub-pixel 35F can obtain clearer and more stable display information.

[0196] Taking an in-vehicle display panel as an example, the shared sub-pixel 35X in the display panel can be set as a strip, and the shared sub-pixel 35X can extend along the first direction X. When the shared sub-pixel 35X is lit, the emitted light from the shared sub-pixel 35X can illuminate the driver's seat and the passenger seat, so that the users in the driver's seat and the passenger seat can obtain the display information shared by the display panel. However, the user in the second direction Y of the display panel will not obtain the shared display information, thus avoiding the display panel from casting a reflection on the windshield and affecting the user's driving vision. This gives the display panel a better directional sharing effect. At the same time, the privacy sub-pixel 35F of the display panel can be set as a dot, so that the display panel has a stable field of view facing the driver's seat. This ensures that the light emission effect of the display panel in all directions is relatively uniform in the privacy display state, so that the user in the driver's seat can obtain relatively clear and stable display information.

[0197] The diameter of the orthogonal projection of the privacy protrusion 72 onto the light-emitting layer 3 is greater than or equal to 6 μm and less than or equal to 40 μm. For example, the diameter of the orthogonal projection of the privacy protrusion 72 onto the light-emitting layer 3 can be 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, etc. The specific value needs to be determined in conjunction with the size of the privacy sub-pixel 35F.

[0198] This configuration ensures that the light emitted from the privacy sub-pixel 35F can reach the privacy protrusion 72, and then be refracted by the privacy protrusion 72 before exiting from the front of the display panel. This increases the light emission efficiency of the front of the display panel and reduces the light emission efficiency of the sides of the display panel, thereby enhancing the privacy effect.

[0199] In some other exemplary embodiments of this disclosure, the orthographic projection of the privacy protrusion 72 onto the light-emitting layer 3 completely covers the privacy sub-pixel 35F, and the distance between the edge of the orthographic projection of the privacy protrusion 72 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F is greater than or equal to 0 and less than or equal to 6 micrometers. For example, the distance between the edge of the orthographic projection of the privacy protrusion 72 onto the light-emitting layer 3 and the edge of the privacy sub-pixel 35F can be 0.5 micrometers, 1 micrometer, 1.5 micrometers, 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, etc.

[0200] The orthographic projection of the shared protrusion 71 onto the light-emitting layer 3 completely covers the shared sub-pixel 35X, and the distance between the edge of the orthographic projection of the shared protrusion 71 onto the light-emitting layer 3 and the edge of the shared sub-pixel 35X is greater than or equal to 0 and less than or equal to 6 micrometers. For example, the distance between the edge of the orthographic projection of the shared protrusion 71 onto the light-emitting layer 3 and the edge of the shared sub-pixel 35X can be 0.5 micrometers, 1 micrometer, 1.5 micrometers, 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, etc.

[0201] In some exemplary embodiments of this disclosure, the shared sub-pixel 35X is configured as a strip extending along a first direction X, such that the shared sub-pixel 35X has a second width and a second length, the second length being greater than the second width, and the second length being a dimension along the first direction X. The privacy sub-pixel 35F is configured as a dot, and the second width of the shared sub-pixel 35X is equal to the diameter of the circumscribed circle of the privacy sub-pixel 35F. Alternatively, the width of the shared sub-pixel 35X may differ from the diameter of the circumscribed circle of the privacy sub-pixel 35F.

[0202] It should be noted that setting the privacy pixel 35F as a dot means that the ratio of the minimum size to the maximum size of the orthographic projection of the privacy pixel 35F on the substrate is greater than or equal to 0.7 and less than or equal to 1. For example, if the privacy pixel 35F is set as an ellipse, the maximum size of the orthographic projection of the privacy pixel 35F on the substrate is the major axis of the ellipse, and the minimum size of the orthographic projection of the privacy pixel 35F on the substrate is the minor axis of the ellipse. That is, the length and width of the privacy pixel 35F are basically the same.

[0203] The shared sub-pixel 35X may include a first shared sub-pixel 35XR, a second shared sub-pixel 35XG, and a third shared sub-pixel 35XB; the privacy sub-pixel 35F may include a first privacy sub-pixel 35FR, a second privacy sub-pixel 35FG, and a third privacy sub-pixel 35FB; the color of the first shared sub-pixel 35XR is the same as the color of the first privacy sub-pixel 35FR, for example, both are red; the color of the second shared sub-pixel 35XG is the same as the color of the first privacy sub-pixel 35FR, for example, both are green; the color of the third shared sub-pixel 35XB is the same as the color of the third privacy sub-pixel 35FB, for example, both are blue.

[0204] Of course, in some other exemplary embodiments of this disclosure, the shared sub-pixel 35X may also include a fourth shared sub-pixel, and the privacy sub-pixel 35F may also include a fourth privacy sub-pixel. The fourth shared sub-pixel and the fourth privacy sub-pixel have the same color, for example, both are white. The second shared sub-pixel 35XG and the second privacy sub-pixel 35FG can be set as two groups to form a pixel arrangement of GGRB, that is, the number of green sub-pixels is twice the number of red sub-pixels, and the number of green sub-pixels is also twice the number of blue sub-pixels; specifically, multiple red sub-pixels and multiple blue sub-pixels can be alternately arranged along the second direction Y to form a first column, and multiple green sub-pixels can be arranged along the second direction Y to form a second column. The gaps between the green sub-pixels in the second column and the red and blue sub-pixels in the first column are basically opposite to each other; multiple first columns and multiple second columns are alternately arranged along the first direction X.

[0205] The following explains the various pixel arrangements.

[0206] Referring to Figures 6-20, pixel region 3a may include a first region 3a1, a second region 3a2, and a third region 3a3. The first region 3a1 and the second region 3a2 are arranged along a first direction X, and the third region 3a3 is located on one side of the first region 3a1 and the second region 3a2 along a second direction Y. A first shared sub-pixel 35XR and a first privacy sub-pixel 35FR are located in the first region 3a1, a second shared sub-pixel 35XG and a second privacy sub-pixel 35FG are located in the second region 3a2, and a third shared sub-pixel 35XB and a third privacy sub-pixel 35FB are located in the second region 3a2.

[0207] The first region 3a1, the second region 3a2, and the third region 3a3 are all set as rectangles extending along the first direction X; in the first direction X, the length of the third region 3a3 is greater than the length of the second region 3a2, and the length of the second region 3a2 is greater than the length of the first region 3a1. Thus, the pixel area 3a formed by splicing the first region 3a1, the second region 3a2, and the third region 3a3 is approximately rectangular.

[0208] Specifically, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are set to at least one line. For example, as shown in Figures 18-20, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are set to one line. Since the requirements for the privacy protection performance of the shared sub-pixel 35X are low, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are not further segmented. Referring to Figures 6-17, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are configured as two lines, with the two first shared sub-pixels 35XR arranged along the second direction Y, the two second shared sub-pixels 35XG arranged along the second direction Y, and the two third shared sub-pixels 35XB also arranged along the second direction Y. This configuration can expand the field of view of the shared sub-pixels 35X in the first direction X and limit the field of view of the shared sub-pixels 35X in the second direction Y, so that the display panel can directionally share the displayed information in the first direction X, avoiding information leakage in other directions of the display panel (e.g., avoiding imaging on the windshield of a vehicle, affecting driving). Of course, in some other exemplary embodiments of this disclosure, the first shared sub-pixels 35XR, the second shared sub-pixels 35XG, and the third shared sub-pixels 35XB can also be configured as three or more lines, and the first shared sub-pixels 35XR, the second shared sub-pixels 35XG, and the third shared sub-pixels 35XB can also extend along other directions, which will not be described in detail here.

[0209] Multiple first privacy sub-pixels 35FR are arranged on the side of the first shared sub-pixel 35XR near the third region 3a3. Specifically, the multiple first privacy sub-pixels 35FR are arranged along the first direction X as at least one column of first privacy sub-pixel 35FRL. For example, the multiple first privacy sub-pixels 35FR can be arranged along the first direction X as one column, two columns or more columns of first privacy sub-pixel 35FRL, and one column, two columns or more columns of first privacy sub-pixel 35FRL are arranged along the second direction Y.

[0210] Multiple second privacy sub-pixels 35FG are arranged on the side of the second shared sub-pixel 35XG near the third region 3a3. Specifically, the multiple second privacy sub-pixels 35FG are arranged along the first direction X as at least one column of second privacy sub-pixel 35FGL. For example, the multiple second privacy sub-pixels 35FG can be arranged along the first direction X as one column, two columns or more columns of second privacy sub-pixel 35FGL, and one column, two columns or more columns of second privacy sub-pixel 35FGL are arranged along the second direction Y.

[0211] Multiple third privacy sub-pixels 35FB are arranged on the side of the third shared sub-pixel 35XB near the first region 3a1. Specifically, the multiple third privacy sub-pixels 35FB are arranged along the first direction X as at least one column of third privacy sub-pixel 35FBL. For example, the multiple third privacy sub-pixels 35FB can be arranged along the first direction X as one column, two columns or more columns of third privacy sub-pixel 35FBL, and one column, two columns or more columns of third privacy sub-pixel 35FBL are arranged along the second direction Y.

[0212] This configuration ensures that within a pixel area 3a, the first privacy sub-pixel 35FR, the second privacy sub-pixel 35FG, and the third privacy sub-pixel 35FB are located in the middle of the second direction Y of pixel area 3a, while the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are located at the opposite edges of pixel area 3a in the second direction Y. In this configuration, during privacy display, the first privacy sub-pixel 35FR, the second privacy sub-pixel 35FG, and the third privacy sub-pixel 35FB within pixel area 3a can be displayed together to form a single privacy pixel. Furthermore, the close proximity of the first privacy sub-pixel 35FR, the second privacy sub-pixel 35FG, and the third privacy sub-pixel 35FB is beneficial for the privacy display effect.

[0213] Referring to Figure 36, multiple pixel areas 3a are configured and arranged in an array. The arrangement of sub-pixels within each pixel area 3a can be identical. In this case, during shared display, the first shared sub-pixel 35XR and the second shared sub-pixel 35XG in one of two adjacent pixel areas 3a in the second direction Y, together with the third shared sub-pixel 35XB in the other pixel area 3a, can be displayed together to form a shared pixel. This ensures that the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB in two adjacent pixel areas 3a in the second direction Y are close to each other and displayed together to form a shared pixel, which is beneficial for the shared display effect.

[0214] It should be noted that when there are multiple pixel areas 3a in the pixel arrangement structure shown in Figures 7-22, the multiple pixel areas 3a are also arranged in an array, and the arrangement of sub-pixels within each pixel area 3a can be the same. That is, the pixel arrangement structure in Figures 7-22 can also be arranged in an array according to the structure shown in Figure 36. Moreover, the privacy display state and shared display state in Figures 7-20 can also be implemented as described above, with the aforementioned beneficial effects, which will not be elaborated further here.

[0215] In some embodiments, in the first direction X, the length of the first shared sub-pixel 35XR is shorter than the length of the second shared sub-pixel 35XG, and the length of the second shared sub-pixel 35XG is shorter than the length of the third shared sub-pixel 35XB. In the first direction X, the length of the first privacy sub-pixel column 35FRL is shorter than the length of the second privacy sub-pixel column 35FGL, and the length of the second privacy sub-pixel column 35FGL is shorter than the length of the third privacy sub-pixel column 35FBL. The first shared sub-pixel 35XR and the second shared sub-pixel 35XG are arranged in a row in the first direction X, and the first privacy sub-pixel column 35FRL and the second privacy sub-pixel column 35FGL are arranged in a row in the first direction X. Joining two shorter pixel regions 3a together helps to increase pixel density.

[0216] This configuration brings the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB closer to the adjacent pixel region 3a. With the corners of the shared opening 321 set as right angles, the corners of the opening of the Fine Metal Mask (FMM) used in etching to form the shared opening 321 are rounded. This results in a smaller distance L1 between the two corners of the shared opening 321 forming the first shared sub-pixel 35XR and the two corners of the first opening FMM1 of the Fine Metal Mask FMM, a smaller distance L2 between the two corners of the shared opening 321 forming the second shared sub-pixel 35XG and the two corners of the second opening FMM2 of the Fine Metal Mask FMM, and a smaller distance L3 between the two corners of the shared opening 321 forming the third shared sub-pixel 35XB and the two corners of the third opening FMM3 of the Fine Metal Mask FMM. This can easily lead to the risk of sub-pixel corner color mixing.

[0217] Referring to Figure 18, the corner of the first shared sub-pixel 35XR away from the first privacy sub-pixel 35FR is provided with a first chamfer. Specifically, the two corners of the first shared sub-pixel 35XR away from the first privacy sub-pixel 35FR are provided with a first chamfer, which can be a rounded chamfer. The corner of the second shared sub-pixel 35XG away from the second privacy sub-pixel 35FG is provided with a second chamfer. Specifically, the two corners of the second shared sub-pixel 35XG away from the second privacy sub-pixel 35FG are provided with a second chamfer, which can also be a rounded chamfer. The corner of the third shared sub-pixel 35XB away from the third privacy sub-pixel 35FB is provided with a third chamfer. Specifically, the two corners of the third shared sub-pixel 35XB away from the third privacy sub-pixel 35FB are provided with a third chamfer, which can also be a rounded chamfer.

[0218] This configuration increases the distance L1 between the two corners of the first shared sub-pixel 35XR and the corner of the fine metal mask FMM, increases the distance L2 between the two corners of the second shared sub-pixel 35XG and the corner of the fine metal mask FMM, and increases the distance L3 between the two corners of the third shared sub-pixel 35XB and the corner of the fine metal mask FMM, thereby reducing the risk of corner color mixing.

[0219] The difference between the radius R1-2 of the chamfer of the first opening FMM1 of the fine metal mask FMM and the radius R1-1 of the first chamfer (R1-2)-(R1-1) is the distance L1 between the corner of the first shared sub-pixel 35XR and the corner of the first opening FMM1 of the fine metal mask FMM. L1 is greater than or equal to the distance H1 between the edge of the first opening FMM1 of the fine metal mask FMM and the edge of the first shared sub-pixel 35XR. H1 is half the width of the pixel definition layer 32 between two adjacent shared sub-pixels 35X (one of which is the first shared sub-pixel 35XR).

[0220] The difference between the radius R2-2 and the radius R2-1 of the second chamfer of the fine metal mask FMM (R2-2)-(R2-1) is the distance L2 between the corner of the second shared sub-pixel 35XG and the corner of the second opening FMM2 of the fine metal mask FMM. L2 is greater than or equal to the distance H2 between the edge of the second opening FMM2 of the fine metal mask FMM and the edge of the second shared sub-pixel 35XG. H2 is half the width of the pixel definition layer 32 between two adjacent shared sub-pixels 35X (one of which is the second shared sub-pixel 35XG).

[0221] The difference between the radius R3-2 and the radius R3-1 of the third chamfer of the fine metal mask FMM (R3-2)-(R3-1) is the distance L3 between the corner of the third shared sub-pixel 35XB and the corner of the third opening FMM3 of the fine metal mask FMM. L3 is greater than or equal to the distance H3 between the edge of the third opening FMM3 of the fine metal mask FMM and the edge of the third shared sub-pixel 35XB. H3 is half the width of the pixel definition layer 32 between two adjacent shared sub-pixels 35X (one of which is the third shared sub-pixel 35XB).

[0222] Of course, in some other exemplary embodiments of this disclosure, the chamfer described above can also be a beveled chamfer.

[0223] Optionally, four first privacy pixels 35FR can be configured, and the center points of the four first privacy pixels 35FR are connected to form a virtual trapezoid XT. That is, the center points of the four first privacy pixels 35FR are located at the four vertices of the virtual trapezoid XT, and the two bases of the virtual trapezoid XT are parallel to the first direction X. That is, the upper and lower bases of the virtual trapezoid XT are both parallel to the first direction X. The virtual trapezoid XT can be an isosceles trapezoid or a non-isosceles trapezoid.

[0224] To meet the proportional requirements of the total area of ​​the first privacy pixel 35FR, the total area of ​​the second privacy pixel 35FG, and the total area of ​​the third privacy pixel 35FB, the area of ​​the first privacy pixel 35FR can be set to be larger (for example, the diameter of the first privacy pixel 35FR can be set to be larger). This results in a smaller distance between two adjacent first privacy pixels 35FR, which cannot meet the process requirements (such as the precision requirements of the mask) and the width requirements of the light-shielding layer group 6. Since there is more space in the first direction X, the distance between two adjacent first privacy pixels 35FR can be appropriately increased to meet the process requirements and the width requirements of the light-shielding layer group 6.

[0225] By placing the center points of the four first privacy pixels 35FR at the four vertices of the dummy trapezoid XT, the distance between two adjacent first privacy pixels 35FR can be increased to meet the process requirements and the width requirements of the light-shielding layer group 6.

[0226] Referring to FIG19, in some exemplary embodiments of this disclosure, a light adjustment layer 7 can be provided based on FIG18, and a planarization layer 8 can be provided on the side of the light adjustment layer 7 facing away from the substrate 1. The specific structures of the light adjustment layer 7 and the planarization layer 8 have been described in detail above, so they will not be repeated here.

[0227] Alternatively, when a shared protrusion 71 and a privacy protrusion 72 are provided, the center point of the orthographic projection of the shared protrusion 71 onto the light-emitting layer 3 can be set at the same point as the center point of the shared sub-pixel 35X, and the center point of the orthographic projection of the privacy protrusion 72 onto the light-emitting layer 3 can be set at the same point as the center point of the privacy sub-pixel 35F. Since the privacy protrusion 72 also has certain size requirements, which have been described in detail above, they will not be repeated here. If the area of ​​the first privacy sub-pixel 35FR is set to be large (for example, the diameter of the first privacy sub-pixel 35FR is set to be large), resulting in a small distance between two adjacent first privacy sub-pixels 35FR, then there will be a large number of interconnected portions between two adjacent privacy protrusions 72. This will prevent the sidewalls of the privacy protrusion 72 from converging light and thus improving light emission efficiency.

[0228] By placing the center points of the four first privacy sub-pixels 35FR at the four vertices of the dummy trapezoid XT, the distance between two adjacent privacy protrusions 72 can be increased, the connection between two privacy protrusions 72 can be reduced, or the two privacy protrusions 72 can be spaced apart, thereby enabling the sidewalls of the privacy protrusions 72 to converge light and improve light emission efficiency.

[0229] Alternatively, two adjacent privacy protrusions 72 can be spaced apart, two adjacent shared protrusions 71 can also be spaced apart, and the privacy protrusions 72 and adjacent shared protrusions 71 can also be spaced apart. This arrangement is beneficial to the forming of the privacy protrusions 72 and the shared protrusions 71, and the peripheral sidewalls of the privacy protrusions 72 and the shared protrusions 71 can both serve to converge light and thus improve light emission efficiency.

[0230] Of course, in some other exemplary embodiments of this disclosure, two adjacent privacy protrusions 72 can be connected to each other. For example, the orthographic projections of two adjacent privacy protrusions 72 on the light-emitting layer 3 can be mutually tangent, so that the diameter of the privacy protrusions 72 can be set to be larger, which is beneficial to the convergence of light and thus improve the light emission efficiency. Moreover, the two adjacent privacy protrusions 72 do not overlap, so as not to reduce the area of ​​the sidewall of the privacy protrusions 72, and to maximize the convergence of light and thus improve the light emission efficiency.

[0231] Adjacent shared protrusions 71 can also be connected to each other. For example, the short sides of the orthographic projections of adjacent shared protrusions 71 on the light-emitting layer 3 can be connected to each other, so that the short side of the privacy protrusion 72 cannot converge the light, but the length of the privacy protrusion 72 can be set to be longer, which is beneficial to converge the light and thus improve the light emission efficiency, and can make up for the deficiency that the short side cannot converge the light; moreover, there is no privacy requirement on the short side perpendicular to the first direction X, so the light does not need to be converged to ensure the sharing requirement.

[0232] The privacy protrusion 72 can also be connected to the adjacent shared protrusion 71. For example, the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3 and the orthographic projection of the adjacent shared protrusion 71 on the light-emitting layer 3 can be tangent, so that the diameter of the privacy protrusion 72 can be set to be larger and the width of the shared protrusion 71 can be set to be wider, which is beneficial to the convergence of light and thus improve the light output efficiency. Moreover, the privacy protrusion 72 and the adjacent shared protrusion 71 do not overlap, so the area of ​​the sidewalls of the privacy protrusion 72 and the shared protrusion 71 will not be reduced, thus maximizing the convergence of light and thus improving the light output efficiency.

[0233] When there are multiple pixel areas 3a, they are arranged in an array. The arrangement of sub-pixels in each pixel area 3a can be the same, as shown in Figure 36 (only the arrangement of sub-pixels in each pixel area 3a is slightly different). Therefore, the specific structure and beneficial effects of multiple pixel areas 3a will not be described in detail here.

[0234] The second privacy pixel 35FG of the two adjacent columns of the second privacy pixel column 35FGL is set relative to each other, and the third privacy pixel 35FB of the two adjacent columns of the third privacy pixel column 35FBL is set relative to each other.

[0235] Referring to Figures 6-15, in some exemplary embodiments of this disclosure, a plurality of first privacy pixels 35FR are arranged along the first direction X to form two columns of first privacy pixels 35FRL, each column including two first privacy pixels 35FR; a plurality of second privacy pixels 35FG are arranged along the first direction X to form two columns of second privacy pixels 35FGL, each column including five second privacy pixels 35FG; a plurality of third privacy pixels 35FB are arranged along the first direction X to form two columns of third privacy pixels 35FBL, each column including five third privacy pixels 35FB. The first privacy pixels 35FR in adjacent columns of first privacy pixels 35FRL are positioned opposite each other. The second privacy pixels 35FG in adjacent columns of second privacy pixels 35FGL are positioned opposite each other. The staggered setting of the third privacy pixel 35FB of two adjacent columns of third privacy pixel 35FBL can reduce the total width of the two adjacent columns of third privacy pixel 35FBL in the second direction Y while maintaining the spacing between the two adjacent third privacy pixel 35FB, thereby reducing the total width of the pixel area 3a in the second direction Y, which is beneficial to improving pixel density.

[0236] It should be noted that "relative setting" refers to the line connecting the center points of two identically ordered privacy pixels 35F (e.g., first privacy pixel 35FR, second privacy pixel 35FG) in two adjacent privacy pixel columns (e.g., first privacy pixel column 35FRL, second privacy pixel column 35FGL) being perpendicular to the first direction X. "Offset setting" refers to the line connecting the center points of two identically ordered privacy pixels 35F (e.g., third privacy pixel 35FB) in two adjacent privacy pixel columns (e.g., third privacy pixel column 35FBL) forming an acute angle with the first direction X.

[0237] Of course, in some other example embodiments of this disclosure, the first privacy pixels 35FR of two adjacent columns of first privacy pixel columns 35FRL may be misaligned, the second privacy pixels 35FG of two adjacent columns of second privacy pixel columns 35FGL may be misaligned, and the third privacy pixels 35FB of two adjacent columns of third privacy pixel columns 35FBL may be relatively aligned.

[0238] Alternatively, referring to Figures 6-17, the lengths of the two third shared sub-pixels 35XB can be different in the first direction X. Specifically, the two third shared sub-pixels 35XB are the third long shared sub-pixel 35XBC and the third short shared sub-pixel 35XBD. In the first direction X, the length of the third short shared sub-pixel 35XBD is less than the length of the third long shared sub-pixel 35XBC. Moreover, the third shared sub-pixel 35XB closer to the first region 3a1 is shorter in the first direction X, that is, the third shared sub-pixel 35XB closer to the first region 3a1 is the third short shared sub-pixel 35XBD. With this setting, the third region 3a3 also has a spare position 3a3K (represented by the thick black solid line in the figure), and the third short shared sub-pixel 35XBD and the spare position 3a3K are set opposite each other in the first direction X. It can also be said that the spare position 3a3K is formed because the length of the third short shared sub-pixel 35XBD is set shorter. In addition to the two columns of third privacy sub-pixels 35FBL, there is also an independent third privacy sub-pixel 35FBD. This independent third privacy sub-pixel 35FBD occupies a portion of the empty position 3a3K, that is, this independent third privacy sub-pixel 35FBD occupies the empty position formed by the third short shared sub-pixel 35XBD.

[0239] There are requirements for the total area of ​​the third privacy sub-pixel 35FB. If only two columns of the third privacy sub-pixel 35FBL are set, the total area of ​​the third privacy sub-pixel 35FB is too small to meet the requirements. Setting an independent third privacy sub-pixel 35FBD can ensure that the total area of ​​the third privacy sub-pixel 35XB meets the requirements, while also ensuring that the total area of ​​the third privacy sub-pixel 35FB meets the requirements.

[0240] Of course, in some other example embodiments of this disclosure, the independent third privacy pixel 35FBD may not occupy the empty position 3a3K. The empty position 3a3K may be set to meet process requirements (e.g., the accuracy requirements of the mask) and the width requirements of the light-shielding layer group 6.

[0241] With the pixel arrangement described above, referring to Figures 6 and 7, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular, allowing them to fit into the privacy protrusion 72, thereby improving light emission efficiency and ensuring uniformity of light emission from all directions. The diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 10μm. For example, the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc.

[0242] In this case, in the second direction Y, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 10μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc.

[0243] With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5 μm, the privacy pixel aperture ratio is approximately 3.29%. With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 6 μm, the privacy pixel aperture ratio is approximately 4.74%.

[0244] Referring to FIG6, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG7, adjacent shared protrusions 71 may be connected to each other, adjacent privacy protrusions 72 may be connected to each other, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap each other, adjacent privacy protrusions 72 may overlap each other, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap each other.

[0245] Referring to Figures 8 and 9, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all set as rounded squares, allowing for a larger area of ​​these pixels, increasing light extraction efficiency, and facilitating fabrication. The distance between opposite sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the distances between opposite sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0246] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0247] With a distance of 5 μm between the two opposite sides of the first privacy pixel 35FR, the two opposite sides of the second privacy pixel 35FG, and the two opposite sides of the third privacy pixel 35FB, the privacy pixel aperture ratio is approximately 3.87%.

[0248] Referring to FIG8, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG9, adjacent shared protrusions 71 may be connected to each other, adjacent privacy protrusions 72 may be connected to each other, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap each other, adjacent privacy protrusions 72 may overlap each other, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap each other.

[0249] Referring to Figures 10 and 11, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all set to an ellipse shape, allowing for a larger area and increasing light emission efficiency. The minor axis lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the minor axis lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0250] Optionally, the minor axis of the first privacy pixel 35FR, the minor axis of the second privacy pixel 35FG, and the minor axis of the third privacy pixel 35FB are parallel to the first direction X, and the major axis of the first privacy pixel 35FR, the major axis of the second privacy pixel 35FG, and the major axis of the third privacy pixel 35FB are parallel to the second direction Y. In the second direction Y, the major axes of two adjacent first privacy pixels 35FR are on the same straight line, and their minor axes are parallel to each other; the major axes of two adjacent second privacy pixels 35FG are on the same straight line, and their minor axes are parallel to each other; the third privacy pixels 35FB of two adjacent columns of third privacy pixels 35FBL are staggered, and the major axes and minor axes of multiple third privacy pixels 35FB are parallel to each other.

[0251] Since five second privacy pixels 35FG are set in the first direction X, and two second privacy pixels 35FG are set in the second direction Y, the distance between two adjacent second privacy pixels 35FG in the second direction Y can be set to be wider, without occupying a large space in the pixel area 3a, which is beneficial to pixel arrangement and improves pixel density.

[0252] Of course, in some other exemplary embodiments of this disclosure, the minor axis of the first privacy pixel 35FR, the minor axis of the second privacy pixel 35FG, and the minor axis of the third privacy pixel 35FB may be parallel to the second direction Y, and the major axis of the first privacy pixel 35FR, the major axis of the second privacy pixel 35FG, and the major axis of the third privacy pixel 35FB may be parallel to the first direction X.

[0253] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0254] With the minor axis lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5 μm, the aperture ratio of the privacy pixel is approximately 5.27%.

[0255] Referring to FIG10, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG11, adjacent shared protrusions 71 may be connected to each other, adjacent privacy protrusions 72 may be connected to each other, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap each other, adjacent privacy protrusions 72 may overlap each other, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap each other.

[0256] Referring to Figures 12 and 13, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all set as rounded rectangles, which allows for a larger area of ​​the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB, increasing light extraction efficiency and facilitating fabrication. The short side lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the short side lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0257] Optionally, the short sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are parallel to the first direction X, while the long sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are parallel to the second direction Y. In the first direction X, the short sides of adjacent first privacy pixels 35FR are on the same straight line, and their long sides are parallel to each other. In the second direction Y, the long sides of adjacent first privacy pixels 35FR are on the same straight line, and their short sides are parallel to each other. In the first direction X, the short sides of adjacent second privacy pixels 35FG are on the same straight line, and their long sides are parallel to each other. In the second direction Y, the long sides of adjacent second privacy pixels 35FG are on the same straight line, and their short sides are parallel to each other. The third privacy pixels 35FB of two adjacent columns of third privacy pixels 35FBL are staggered, and the long axes and short axes of multiple third privacy pixels 35FB are parallel to each other.

[0258] Since five second privacy pixels 35FG are set in the first direction X, and two second privacy pixels 35FG are set in the second direction Y, the distance between two adjacent second privacy pixels 35FG in the second direction Y can be set to be wider, without occupying a large space in the pixel area 3a, which is beneficial to pixel arrangement and improves pixel density.

[0259] Of course, in some other exemplary embodiments of this disclosure, the short side of the first privacy pixel 35FR, the short side of the second privacy pixel 35FG, and the short side of the third privacy pixel 35FB may be parallel to the second direction Y, and the long side of the first privacy pixel 35FR, the long side of the second privacy pixel 35FG, and the long side of the third privacy pixel 35FB may be parallel to the first direction X.

[0260] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0261] With the short side lengths of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5μm, the privacy pixel aperture ratio is approximately 6.38%.

[0262] Referring to FIG12, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG13, adjacent shared protrusions 71 may be connected to each other, adjacent privacy protrusions 72 may be connected to each other, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap each other, adjacent privacy protrusions 72 may overlap each other, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap each other.

[0263] Referring to Figures 6-13, the center point of the first privacy sub-pixel 35FR and the center point of the orthogonal projection of its corresponding privacy protrusion 72 on the light-emitting layer 3 are set at the same center point; the center point of the second privacy sub-pixel 35FG and the center point of the orthogonal projection of its corresponding privacy protrusion 72 on the light-emitting layer 3 are set at the same center point; and the center point of the third privacy sub-pixel 35FB and the center point of the orthogonal projection of its corresponding privacy protrusion 72 on the light-emitting layer 3 are set at the same center point.

[0264] Referring to Figures 14 and 15, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all set as rounded squares. The distance between the opposite sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the distance between the opposite sides of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0265] Alternatively, the first privacy pixel 35FR and the privacy protrusion 72 are not set to share a common center point on the orthogonal projection of the first privacy pixel 35FRL onto the light-emitting layer 3. Instead, the two columns of first privacy pixel 35FRL are close to each other, that is, the two columns of first privacy pixel 35FRL are offset towards each other along the second direction Y, so that the multiple center points of multiple first privacy pixel 35FR of the two columns of first privacy pixel 35FRL are located between the multiple center points of the orthogonal projection of the two columns of privacy protrusion 72 onto the light-emitting layer 3. The second privacy pixel 35FG and the privacy protrusion 72 are also not set to share a common center point on the orthogonal projection of the second privacy pixel 35FGL onto the light-emitting layer 3. Instead, the two columns of second privacy pixel 35FGL are close to each other, that is, the two columns of second privacy pixel 35FGL are offset towards each other. Both columns of the second privacy pixel 35FB and the privacy protrusion 72 are offset towards each other along the second direction Y, such that the center points of the multiple second privacy pixel 35FG of the two columns of the second privacy pixel 35FGL are located between the center points of the orthogonal projections of the two columns of privacy protrusions 72 on the light-emitting layer 3; the third privacy pixel 35FB and the orthogonal projections of the privacy protrusions 72 on the light-emitting layer 3 are not set to share a center point, but the two columns of the third privacy pixel 35FBL are close to each other, that is, both columns of the third privacy pixel 35FBL are offset towards each other along the second direction Y, such that the center points of the multiple third privacy pixel 35FB of the two columns of the third privacy pixel 35FBL are located between the center points of the orthogonal projections of the two columns of privacy protrusions 72 on the light-emitting layer 3.

[0266] The center points of a column of first privacy pixels 35FR are aligned on a straight line, and the center points of a column of privacy protrusions 72 opposite to the first privacy pixels 35FR are also aligned on a straight line. The center points of a column of second privacy pixels 35FG are aligned on a straight line, and the center points of a column of privacy protrusions 72 opposite to the second privacy pixels 35FG are also aligned on a straight line. The center points of a column of third privacy pixels 35FB are aligned on a straight line, and the center points of a column of privacy protrusions 72 opposite to the third privacy pixels 35FB are also aligned on a straight line.

[0267] Of course, in some other exemplary embodiments of this disclosure, the two first privacy pixel columns 35FRL can be offset away from each other along the second direction Y, and the two second privacy pixel columns 35FGL can be offset away from each other along the second direction Y. Alternatively, the first privacy pixel 35FR can also be offset relative to the privacy protrusion 72 along the first direction X, the second privacy pixel column 35FGL can also be offset relative to the privacy protrusion 72 along the first direction X, and the third privacy pixel column 35FBL can also be offset relative to the privacy protrusion 72 along the first direction X. Alternatively, the two first privacy pixel columns 35FRL can be offset away from or near each other along the first direction X, and the two second privacy pixel columns 35FGL can be offset away from or near each other along the first direction X.

[0268] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0269] With a distance of 5 μm between the two opposite sides of the first privacy pixel 35FR, the distance between the two opposite sides of the second privacy pixel 35FG, and the distance between the two opposite sides of the third privacy pixel 35FB, the privacy pixel aperture ratio is approximately 5.12%.

[0270] Referring to FIG14, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG15, adjacent shared protrusions 71 may be interconnected, and adjacent privacy protrusions 72 may be interconnected. For example, the orthographic projections of adjacent privacy protrusions 72 on the light-emitting layer 3 may be externally tangent to each other, while adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap, adjacent privacy protrusions 72 may overlap, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap.

[0271] It should be noted that the diameters of the first privacy sub-pixel 35FR, the second privacy sub-pixel 35FG, and the third privacy sub-pixel 35FB can be the same or different; the widths of the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB can be the same or different.

[0272] Referring to Figures 16 and 17, in some exemplary embodiments of this disclosure, the first privacy pixel column 35FRL can be configured as three columns, with the first privacy pixels 35FR of adjacent columns of the first privacy pixel column 35FRL being staggered; the second privacy pixel column 35FGL can be configured as three columns, with the second privacy pixels 35FG of adjacent columns of the second privacy pixel column 35FGL being staggered; for example, a first privacy pixel column 35FRL can be added between adjacent columns of the first privacy pixel column 35FRL and a second privacy pixel column 35FGL can be added between adjacent columns of the second privacy pixel column 35FGL in the structure shown in Figures 6–15 above. The third privacy pixel column 35FBL can be set to two columns, with the third privacy pixels 35FB of the two columns of third privacy pixel columns 35FBL arranged opposite each other. For example, a third privacy pixel 35FB can be added between two adjacent third privacy pixels 35FB in the structure shown in Figures 6-15. A third privacy pixel 35FB can be added at the beginning of one column of third privacy pixel columns 35FBL and at the end of the other column of third privacy pixel columns 35FBL. In this way, the number of third privacy pixels 35FB included in one column of third privacy pixel columns 35FBL shown in Figures 16 and 17 is twice the number of third privacy pixels 35FB included in one column of third privacy pixel columns 35FBL shown in Figures 6-15.

[0273] In this configuration, the middle column of first privacy pixel array 35FRL is not covered by the orthogonal projection of the privacy protrusion 72 onto the light-emitting layer 3, and the middle column of second privacy pixel array 35FGL is also not covered by the orthogonal projection of the privacy protrusion 72 onto the light-emitting layer 3. In other words, neither the aforementioned additional first privacy pixel array 35FRL nor the additional privacy pixel array 35FGL is covered by the orthogonal projection of the privacy protrusion 72 onto the light-emitting layer 3. This configuration increases the pixel density of the first privacy pixel 35FR and the second privacy pixel 35FG, thereby improving light extraction efficiency.

[0274] The privacy protrusions 72, positioned opposite to the two columns of third privacy sub-pixels 35FBL, are misaligned. Because the third privacy sub-pixels 35FB of the two columns of third privacy sub-pixels 35FBL are positioned opposite each other, a portion of the third privacy sub-pixels 35FB are not covered by the orthogonal projection of the privacy protrusions 72 onto the light-emitting layer 3. In other words, the aforementioned additional third privacy sub-pixels 35FB are not covered by the orthogonal projection of the privacy protrusions 72 onto the light-emitting layer 3. This arrangement increases the pixel density of the third privacy sub-pixels 35FB, thereby improving light extraction efficiency.

[0275] Alternatively, referring to Figures 16-17, the lengths of the two third shared sub-pixels 35XB can be different in the first direction X. The two third shared sub-pixels 35XB are the third long shared sub-pixel 35XBC and the third short shared sub-pixel 35XBD. In the first direction X, the length of the third short shared sub-pixel 35XBD is less than the length of the third long shared sub-pixel 35XBC. Moreover, the third shared sub-pixel 35XB closer to the first region 3a1 is shorter in the first direction X, that is, the third shared sub-pixel 35XB closer to the first region 3a1 is the third short shared sub-pixel 35XBD. With this setting, the third region 3a3 also has a spare position 3a3K (represented by the thick black solid line in the figure), and the third short shared sub-pixel 35XBD and the spare position 3a3K are set opposite each other in the first direction X. It can also be said that the spare position 3a3K is formed because the length of the third short shared sub-pixel 35XBD is set shorter. In addition to the two columns of third privacy sub-pixels 35FBL, there is also an independent third privacy sub-pixel 35FBD. This independent third privacy sub-pixel 35FBD occupies part of the empty position 3a3K, that is, the independent third privacy sub-pixel 35FBD occupies the empty position 3a3K formed by the third short shared sub-pixel 35XBD.

[0276] There are requirements for the total area of ​​the third privacy sub-pixel 35FB. If only two columns of the third privacy sub-pixel 35FBL are set, the total area of ​​the third privacy sub-pixel 35FB is too small to meet the requirements. Setting an independent third privacy sub-pixel 35FBD can ensure that the total area of ​​the third privacy sub-pixel 35XB meets the requirements, while also ensuring that the total area of ​​the third privacy sub-pixel 35FB meets the requirements.

[0277] Of course, in some other example embodiments of this disclosure, the independent third privacy pixel 35FBD may not occupy the empty position 3a3K. The empty position 3a3K may be set to meet process requirements (e.g., the accuracy requirements of the mask) and the width requirements of the light-shielding layer group 6.

[0278] The first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular. The diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0279] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0280] With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5 μm, the privacy pixel aperture ratio is approximately 4.34%.

[0281] Of course, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can also be set to various shapes described above, or other shapes not described above, which will not be described one by one here.

[0282] Referring to FIG16, adjacent shared protrusions 71 may be spaced apart, adjacent privacy protrusions 72 may be spaced apart, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Referring to FIG17, adjacent shared protrusions 71 may be connected to each other, adjacent privacy protrusions 72 may be connected to each other, and adjacent shared protrusions 71 and privacy protrusions 72 may be spaced apart. Of course, in some other exemplary embodiments of this disclosure, adjacent shared protrusions 71 may overlap each other, adjacent privacy protrusions 72 may overlap each other, and adjacent shared protrusions 71 and privacy protrusions 72 may overlap each other.

[0283] Referring to Figures 6, 8, 10, 12, 14, and 16, adjacent privacy protrusions 72 can be spaced apart, adjacent shared protrusions 71 can also be spaced apart, and privacy protrusions 72 and adjacent shared protrusions 71 can also be spaced apart. This arrangement facilitates the forming of privacy protrusions 72 and shared protrusions 71, and the peripheral sidewalls of privacy protrusions 72 and shared protrusions 71 can both converge light and improve light emission efficiency.

[0284] Referring to Figures 7, 9, 11, 13, 15, and 17, two adjacent privacy protrusions 72 can be connected to each other. For example, the orthographic projections of two adjacent privacy protrusions 72 on the light-emitting layer 3 can be mutually tangent, so that the diameter of the privacy protrusions 72 can be set to be larger, which is beneficial to the convergence of light and thus improve the light emission efficiency. Moreover, the two adjacent privacy protrusions 72 do not overlap, so the area of ​​the sidewall of the privacy protrusions 72 will not be reduced, and the convergence of light can be maximized to improve the light emission efficiency.

[0285] Adjacent shared protrusions 71 can also be connected to each other. For example, the short sides of the orthographic projections of adjacent shared protrusions 71 on the light-emitting layer 3 can be connected to each other, so that the short side of the privacy protrusion 72 cannot converge the light, but the length of the privacy protrusion 72 can be set to be longer, which is beneficial to converge the light and thus improve the light emission efficiency, and can make up for the deficiency that the short side cannot converge the light; moreover, there is no privacy requirement on the short side perpendicular to the first direction X, so the light does not need to be converged to ensure the sharing requirement.

[0286] The privacy protrusion 72 can also be connected to the adjacent shared protrusion 71. For example, the orthographic projection of the privacy protrusion 72 on the light-emitting layer 3 and the orthographic projection of the adjacent shared protrusion 71 on the light-emitting layer 3 can be tangent, so that the diameter of the privacy protrusion 72 can be set to be larger and the width of the shared protrusion 71 can be set to be wider, which is beneficial to the convergence of light and thus improve the light output efficiency. Moreover, the privacy protrusion 72 and the adjacent shared protrusion 71 do not overlap, so the area of ​​the sidewalls of the privacy protrusion 72 and the shared protrusion 71 will not be reduced, thus maximizing the convergence of light and thus improving the light output efficiency.

[0287] Alternatively, the first privacy sub-pixel column 35FRL can be aligned with the second privacy sub-pixel column 35FGL in the first direction X, and the first shared sub-pixel 35XR can be aligned with the second shared sub-pixel 35XG in the first direction X; such an arrangement can facilitate process fabrication and computational design.

[0288] Of course, the first privacy sub-pixel column 35FRL and the second privacy sub-pixel column 35FGL can also be misaligned, as can the first shared sub-pixel 35XR and the second shared sub-pixel 35XG. Such a setting can improve the aperture ratio.

[0289] Referring to FIG20, a plurality of first privacy pixels 35FR are arranged into at least two columns of first privacy pixel columns 35FRL extending along the first direction X, and the first privacy pixels 35FR of adjacent columns of first privacy pixel columns 35FRL are staggered, with the stagger angle α1 being greater than 0° and less than 90°. For example, the stagger angle α1 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0290] Multiple second privacy pixels 35FG are arranged into at least two columns of second privacy pixel columns 35FGL extending along the first direction X, and the second privacy pixels 35FG of adjacent columns of second privacy pixel columns 35FGL are staggered, with a stagger angle α2 greater than 0° and less than 90°. For example, the stagger angle α2 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0291] Multiple third privacy pixels 35FB are arranged into at least two columns of third privacy pixel columns 35FBL extending along the first direction X. The third privacy pixels 35FB in adjacent columns of third privacy pixel columns 35FBL are staggered, with a stagger angle α3 greater than 0° and less than 90°. For example, the stagger angle α3 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. This arrangement reduces the mutual interference of light emitted by adjacent privacy pixels 35F in the first direction X and the second direction Y.

[0292] It should be noted that the misalignment angle can be the angle between the connecting line between the center points of two first privacy pixels 35FR in the same order in two adjacent columns of first privacy pixel 35FRL and the second direction Y.

[0293] The misalignment angles α1, α2, and α3 can be the same, which facilitates design and manufacturing processes. Of course, the misalignment angles α1, α2, and α3 can also be different.

[0294] Referring to FIG21, a plurality of first privacy sub-pixels 35FR are disposed on opposite sides of the first shared sub-pixel 35XR, a plurality of second privacy sub-pixels 35FG are disposed on opposite sides of the second shared sub-pixel 35XG, and a plurality of third privacy sub-pixels 35FB are disposed on opposite sides of the third shared sub-pixel 35XB.

[0295] Specifically, the first shared sub-pixel 35XR is configured as a rectangle extending along the first direction X. A column of first privacy sub-pixels 35FRL is provided on one side of the second direction Y of the first shared sub-pixel 35XR, and a column of first privacy sub-pixels 35FRL is provided on the opposite side of the second direction Y of the first shared sub-pixel 35XR. A column of first privacy sub-pixels 35FRL may include at least two first privacy sub-pixels 35FR.

[0296] The second shared sub-pixel 35XG may include a first part 35XG1, a second part 35XG2, and a third part 35XG3 connected in sequence, i.e., the first part 35XG1 and the third part 35XG3 are connected to the opposite ends of the second part 35XG2; the second part 35XG2 extends along the second direction Y, and the first part 35XG1 and the third part 35XG3 extend along the first direction X, and the first part 35XG1 and the third part 35XG3 are located on opposite sides of the second part 35XG2 in the first direction X, i.e., the first part 35XG1 and the third part 35XG3 extend one-to-one in the first direction X away from the second part 35XG2, so that the second shared sub-pixel 35XG forms a roughly stepped structure; and the third part 35XG3 is set closer to the third region 3a3 than the first part 35XG1.

[0297] The third shared sub-pixel 35XB may include a fourth part 35XB1, a fifth part 35XB2, and a sixth part 35XB3 connected in sequence, that is, the fourth part 35XB1 and the sixth part 35XB3 are connected to the opposite ends of the fifth part 35XB2; the fifth part 35XB2 extends along the second direction Y, and the fourth part 35XB1 and the sixth part 35XB3 extend along the first direction X, and the fourth part 35XB1 and the sixth part 35XB3 are located on opposite sides of the fifth part 35XB2 in the first direction X, that is, the fourth part 35XB1 and the sixth part 35XB3 extend one-to-one along the first direction X away from the fifth part 35XB2, so that the third shared sub-pixel 35XB forms a roughly stepped structure, and the fourth part 35XB1 is set closer to the first region 3a1 than the sixth part 35XB3.

[0298] A portion of the second privacy pixels 35FG are located on the side of the first portion 35XG1 closer to the third region 3a3. This portion of the second privacy pixels 35FG can be four in number, arranged in an array. Another portion of the second privacy pixels 35FG are located on the side of the third portion 35XG3 furthest from the third region 3a3. This portion of the second privacy pixels 35FG can also be four in number, arranged in an array. A portion of the third privacy pixels 35FB are located on the side of the fourth portion 35XB1 furthest from the first region 3a1. This portion of the third privacy pixels 35FB can be six in number, arranged in an array. Another portion of the third privacy pixels 35FB are located on the side of the sixth portion 35XB3 closer to the second region 3a2. This portion of the third privacy pixels 35FB can also be six in number, arranged in an array.

[0299] This configuration increases the total width of the second shared sub-pixel 35XG and the third shared sub-pixel 35XB in the second direction Y, and also brings the light-emitting centers of the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB closer together, which is beneficial to the display effect. Similarly, this configuration increases the total width of multiple first privacy sub-pixels 35FR, multiple second privacy sub-pixels 35FG, and multiple third privacy sub-pixels 35FB in the second direction Y, and also brings the light-emitting centers of the multiple first privacy sub-pixels 35FR, the multiple second privacy sub-pixels 35FG, and the multiple third privacy sub-pixels 35FB closer together, which is also beneficial to the display effect.

[0300] Of course, in some other exemplary embodiments of this disclosure, the second shared sub-pixel 35XG and the third shared sub-pixel 35XB can also be configured as rectangles extending along the first direction X, with at least two second privacy sub-pixels 35FG provided on each side of the second shared sub-pixel 35XG in the second direction Y, and at least two third privacy sub-pixels 35FB provided on each side of the third shared sub-pixel 35XB in the second direction Y. The second shared sub-pixel 35XG and the third shared sub-pixel 35XB can also be configured as curved structures, with the curved structure generally extending along the first direction X; with at least two second privacy sub-pixels 35FG provided on each side of the second shared sub-pixel 35XG in the second direction Y, and at least two third privacy sub-pixels 35FB provided on each side of the third shared sub-pixel 35XB in the second direction Y.

[0301] It should be noted that the second shared sub-pixel 35XG is defined by the shape of the shared opening 321 on the pixel definition layer 32; the shared electrode 311 of the second shared sub-pixel 35XG is set to a shape that matches the second shared sub-pixel 35XG, and the shared electrode 311 of the second shared sub-pixel 35XG is larger than the shared opening 321 of the second shared sub-pixel 35XG, so that the shared opening 321 of the second shared sub-pixel 35XG is located within the edge line of the shared electrode 311 of the second shared sub-pixel 35XG. Similarly, the third shared sub-pixel 35XB is defined by the shape of the shared opening 321 on the pixel definition layer 32; the shared electrode 311 of the third shared sub-pixel 35XB is set to a shape that matches the third shared sub-pixel 35XB, and the shared electrode 311 of the third shared sub-pixel 35XB is larger than the shared opening 321 of the third shared sub-pixel 35XB, so that the shared opening 321 of the third shared sub-pixel 35XB is located within the edge line of the shared electrode 311 of the third shared sub-pixel 35XB.

[0302] Referring to Figure 22, the first shared sub-pixel 35XR can be set to two, with at least two first privacy sub-pixels 35FR located between the two first shared sub-pixels 35XR; the second shared sub-pixel 35XG can be set to two, with at least two second privacy sub-pixels 35FG located between the two second shared sub-pixels 35XG; the third shared sub-pixel 35XB can be set to two, with at least two third privacy sub-pixels 35FB located between the two third shared sub-pixels 35XB.

[0303] Specifically, the first shared sub-pixel 35XR is set as a rectangle extending along the first direction X, and two first shared sub-pixels 35XR are arranged along the second direction Y; two first privacy sub-pixels 35FR are set between the two first shared sub-pixels 35XR, and the two first privacy sub-pixels 35FR are arranged in a column along the first direction X. Of course, three or more first privacy sub-pixels 35FR can be set between the two first shared sub-pixels 35XR, and the three or more first privacy sub-pixels 35FR can be arranged in two or more columns along the first direction X.

[0304] Two second shared sub-pixels 35XG are located at two opposite corners of the second region 3a2. One second shared sub-pixel 35XG is located at the corner closer to the first region 3a1 and farther from the third region 3a3, while the other second shared sub-pixel 35XG is located at the corner farther from the first region 3a1 and closer to the third region 3a3. The corners where the two second shared sub-pixels 35XG are close to each other are rounded to avoid interference with the second privacy sub-pixel 35FG.

[0305] Multiple second privacy sub-pixels 35FG are arranged in a zigzag structure between two second shared sub-pixels 35XG. Specifically, the multiple second privacy sub-pixels 35FG are arranged in three columns of second privacy sub-pixels 35FGL. The two columns at both ends of the three columns of second privacy sub-pixels 35FGL are set perpendicular to the middle column, so that the multiple second privacy sub-pixels 35FG are connected to form a roughly stepped shape. The middle column of second privacy sub-pixels 35FGL is inclined relative to the first direction X and the second direction Y between the two second shared sub-pixels 35XG. That is, the middle column of second privacy sub-pixels 35FGL has a set angle with both the first direction X and the second direction Y.

[0306] Two third shared sub-pixels 35XB are located at two opposite corners of the third region 3a3, with one third shared sub-pixel 35XB located at the corner closest to the second region 3a2 and the other second shared sub-pixel 35XG located at the corner furthest from the second region 3a2. The two third shared sub-pixels 35XB are configured as right-angled trapezoids, with the shorter upper base of the trapezoid closer to the center of the third region 3a3. The corners where the two third shared sub-pixels 35XB are close to each other are rounded to avoid interference with the third privacy sub-pixel 35FB.

[0307] Multiple third privacy sub-pixels 35FB are arranged in a zigzag structure between two third shared sub-pixels 35XB. Specifically, the multiple third privacy sub-pixels 35FB are arranged in three columns of third privacy sub-pixels 35FBL. The three columns of third privacy sub-pixels 35FBL are parallel to each other, and the two columns at both ends are offset from the middle column, so that the multiple third privacy sub-pixels 35FB are connected to form a step shape with approximately two steps. The middle column of third privacy sub-pixels 35FBL is inclined relative to the first direction X and the second direction Y between the two third shared sub-pixels 35XB. That is, the middle column of third privacy sub-pixels 35FBL has a set angle with both the first direction X and the second direction Y.

[0308] This configuration increases the total width of the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB in the second direction Y, and also brings the light-emitting centers of the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB closer together, which is beneficial to the display effect. Similarly, this configuration increases the total width of multiple first privacy sub-pixels 35FR, multiple second privacy sub-pixels 35FG, and multiple third privacy sub-pixels 35FB in the second direction Y, and also brings the light-emitting centers of the multiple first privacy sub-pixels 35FR, the multiple second privacy sub-pixels 35FG, and the multiple third privacy sub-pixels 35FB closer together, which is also beneficial to the display effect.

[0309] Of course, in some other exemplary embodiments of this disclosure, the second shared sub-pixel 35XG and the third shared sub-pixel 35XB may also be configured as rectangles extending along the first direction X, with one, two or more columns of second privacy sub-pixel columns 35FGL between the two second shared sub-pixels 35XG, and one, two or more columns of third privacy sub-pixel columns 35FBL between the two third shared sub-pixels 35XB.

[0310] Referring to FIG23, in some exemplary embodiments of this disclosure, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are configured as strips extending along the first direction X.

[0311] Multiple first privacy pixels 35FR are arranged along the first direction X to form at least one column of first privacy pixels 35FRL, for example, multiple first privacy pixels 35FR are arranged along the first direction X to form two columns of first privacy pixels 35FRL. Multiple second privacy pixels 35FG are arranged along the first direction X to form at least one column of second privacy pixels 35FGL, for example, multiple second privacy pixels 35FG are arranged along the first direction X to form two columns of second privacy pixels 35FGL. Multiple third privacy pixels 35FB are arranged along the first direction X to form at least one column of third privacy pixels 35FBL, for example, multiple third privacy pixels 35FB are arranged along the first direction X to form two columns of third privacy pixels 35FBL.

[0312] A column of first privacy sub-pixel column 35FRL and a column of second privacy sub-pixel column 35FGL arranged along the first direction X form a privacy group 35FZ. Therefore, two columns of first privacy sub-pixel columns 35FRL and two columns of second privacy sub-pixel columns 35FGL arranged along the first direction X form two privacy groups 35FZ. A first shared sub-pixel 35XR and a second shared sub-pixel 35XG arranged along the first direction X form a shared group 35XZ. Therefore, two first shared sub-pixels 35XR and two second shared sub-pixels 35XG arranged along the first direction X form two shared groups 35XZ. The privacy group 35FZ, the third privacy sub-pixel column 35FBL, the third shared sub-pixel 35XB, and the shared group 35XZ are arranged sequentially along the second direction Y. For example, two columns of privacy groups 35FZ, two columns of third privacy sub-pixel columns 35FBL, two third shared sub-pixels 35XB, and two columns of shared group 35XZ are arranged sequentially along the second direction Y.

[0313] The first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular. The diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0314] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0315] With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5 μm, the pixel aperture ratio is approximately 16.8%.

[0316] Of course, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can also be set to various shapes described above, or other shapes not described above, which will not be described in detail here. Moreover, the number of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be set as needed, as can the number of the first privacy pixel column 35FRL, the second privacy pixel column 35FGL, and the third privacy pixel column 35FBL.

[0317] Referring to FIG24, in some exemplary embodiments of this disclosure, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are configured as strips extending along the first direction X.

[0318] Multiple first privacy pixels 35FR are arranged along the first direction X to form at least one column of first privacy pixels 35FRL, for example, multiple first privacy pixels 35FR are arranged along the first direction X to form two columns of first privacy pixels 35FRL. Multiple second privacy pixels 35FG are arranged along the first direction X to form at least one column of second privacy pixels 35FGL, for example, multiple second privacy pixels 35FG are arranged along the first direction X to form three columns of third privacy pixels 35FBL. Multiple third privacy pixels 35FB are arranged along the first direction X to form at least one column of third privacy pixels 35FBL, for example, multiple third privacy pixels 35FB are arranged along the first direction X to form two columns of third privacy pixels 35FBL.

[0319] Pixel region 3a may include a first region 3a1 and a second region 3a2 connected along the first direction X, and the boundary line between the first region 3a1 and the second region 3a2 may be a curve, for example, the boundary line between the first region 3a1 and the second region 3a2 may be a zigzag line (dashed line in the figure).

[0320] The second shared sub-pixel 35XG, the second privacy sub-pixel column 35FGL, and the first privacy sub-pixel column 35FRL are arranged sequentially along the second direction Y and located in the first region 3a1; for example, three second shared sub-pixels 35XG, three columns of second privacy sub-pixels 35FGL, and two columns of first privacy sub-pixels 35FRL are arranged sequentially along the second direction Y and located in the first region 3a1.

[0321] The first shared sub-pixel 35XR, the third shared sub-pixel 35XB, and the third privacy sub-pixel column 35FBL are arranged sequentially along the second direction Y and located in the second region 3a2; for example, two first shared sub-pixels 35XR, four third shared sub-pixels 35XB, and two columns of third privacy sub-pixels 35FBL are arranged sequentially along the second direction Y and located in the second region 3a2.

[0322] The first privacy sub-pixel column 35FRL and the first shared sub-pixel 35XR are located at opposite corners of pixel area 3a, resulting in a relatively large distance between the first privacy sub-pixel column 35FRL and the first shared sub-pixel 35XR.

[0323] Furthermore, the lengths of the two first shared sub-pixels 35XR can be different; for example, the length of the first shared sub-pixel 35XR increases with the increase of its distance from the third shared sub-pixel 35XB. Similarly, the lengths of the two first privacy sub-pixel columns 35FRL can be different; for example, the length of the first privacy sub-pixel column 35FRL increases with the increase of its distance from the second privacy sub-pixel column 35FGL. The lengths of the three second shared sub-pixels 35XG can also be different; for example, the length of the second shared sub-pixel 35XG decreases with the increase of its distance from the second privacy sub-pixel column 35FGL. The lengths of the three second privacy sub-pixel columns 35FGL can be different. For example, the length of the second privacy sub-pixel column 35FGL decreases as the distance from the second shared sub-pixel 35XG increases. The lengths of the four third shared sub-pixels 35XB can be different. For example, the length of the third shared sub-pixel 35XB decreases as the distance from the third privacy sub-pixel column 35FBL increases. The lengths of the two third privacy sub-pixel columns 35FBL can be different. For example, the length of the third privacy sub-pixel column 35FBL decreases as the distance from the third shared sub-pixel 35XB increases.

[0324] Of course, in some other example embodiments of this disclosure, the lengths of the two first shared sub-pixels 35XR can be the same, the lengths of the two columns of first privacy sub-pixels 35FRL can be the same; the lengths of the three second shared sub-pixels 35XG can be the same, the lengths of the three columns of second privacy sub-pixels 35FGL can be the same, the lengths of the four third shared sub-pixels 35XB can be the same, and the lengths of the two columns of third privacy sub-pixels 35FBL can be the same.

[0325] The two adjacent rows of pixel areas 3a in the second direction Y can be staggered, so that the first area 3a1 of the first row and the second area 3a2 of the second row are basically opposite to each other. A pixel arrangement of the second area 3a2 can be added at one end of the second row, and a pixel arrangement of the first area 3a1 can be added at the other end of the second row.

[0326] This configuration results in two first shared sub-pixels 35XR and two columns of first privacy sub-pixels 35FRL forming a first pixel group 35R; three second shared sub-pixels 35XG and three columns of second privacy sub-pixels 35FGL forming a second pixel group 35G; and four third shared sub-pixels 35XB and two columns of third privacy sub-pixels 35FBL forming a third pixel group 35B. The second pixel group 35G, the first pixel group 35R, and the third pixel group 35B are arranged along the second direction Y to form a first unit, and multiple first units are arranged along the second direction Y to form a first column. The third pixel group 35B, the second pixel group 35G, and the first pixel group 35R are arranged along the second direction Y to form a second unit, and multiple second units are arranged along the second direction Y to form a second column. Multiple first columns and multiple second columns are arranged alternately along the first direction X. The pixel groups in the first column and the pixel groups in the second column are staggered. For example, the third pixel group 35B of the second column is partially opposite to the second pixel group 35G and the first pixel group 35R of the first column, and is opposite to the gap between the second pixel group 35G and the first pixel group 35R of the first column.

[0327] When displayed, the first pixel group 35R in the first column, together with the second pixel group 35G and the third pixel group 35B in the adjacent second column, form a pixel, as shown by the area circled in black in Figure 24, which is a triangle-like display area. The adjacent pixels form a triangle display area that is complementary to this triangle.

[0328] The first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular. The diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0329] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0330] With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5μm, the pixel aperture ratio is approximately 20.8%.

[0331] Of course, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can also be set to various shapes described above, or other shapes not described above, which will not be described in detail here. Moreover, the number of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be set as needed, as can the number of the first privacy pixel column 35FRL, the second privacy pixel column 35FGL, and the third privacy pixel column 35FBL.

[0332] Referring to FIG25, in some exemplary embodiments of this disclosure, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are configured as strips extending along the first direction X.

[0333] Pixel region 3a can be set as a rectangle extending along the fourth direction M, which is parallel to the light-emitting layer 3 and forms a first angle with the second direction Y. The first angle is an acute angle, specifically greater than or equal to 30° and less than or equal to 60°. For example, the first angle can be 35°, 40°, 45°, 50°, 55°, etc. The fourth direction M forms a second angle with the first direction X, for example, the first angle and the second angle are complementary angles.

[0334] Pixel region 3a may include a first region 3a1, a second region 3a2, and a third region 3a3 connected sequentially along the fourth direction M; the first region 3a1, the second region 3a2, and the third region 3a3 may all be set as rectangles.

[0335] The first privacy sub-pixel 35FR and the first shared sub-pixel 35XR are located in the first region 3a1, and the first privacy sub-pixel 35FR is located on one side of the second direction Y of the first shared sub-pixel 35XR; for example, all the first privacy sub-pixels 35FR may be located on one side of the second direction Y of all the first shared sub-pixels 35XR.

[0336] The second privacy sub-pixel 35FG and the second shared sub-pixel 35XG are located in the second region 3a2, and the second privacy sub-pixel 35FG is located on one side of the second direction Y of the second shared sub-pixel 35XG; for example, all the second privacy sub-pixels 35FG may be located on one side of the second direction Y of all the second shared sub-pixels 35XG.

[0337] The third privacy sub-pixel 35FB and the third shared sub-pixel 35XB are located in the third region 3a3, and the third privacy sub-pixel 35FB is located on one side of the second direction Y of the third shared sub-pixel 35XB; for example, all the third privacy sub-pixels 35FB may be located on one side of the second direction Y of all the third shared sub-pixels 35XB.

[0338] Of course, in some other exemplary embodiments of this disclosure, the first privacy sub-pixel 35FR and the first shared sub-pixel 35XR may be alternately arranged in the second direction Y, the second privacy sub-pixel 35FG and the second shared sub-pixel 35XG may be alternately arranged in the second direction Y, and the third privacy sub-pixel 35FB and the third shared sub-pixel 35XB may be alternately arranged in the second direction Y.

[0339] Multiple first privacy pixels 35FR are arranged along the first direction X to form at least one column of first privacy pixels 35FRL, for example, multiple first privacy pixels 35FR are arranged along the first direction X to form two columns of first privacy pixels 35FRL. Multiple second privacy pixels 35FG are arranged along the first direction X to form at least one column of second privacy pixels 35FGL, for example, multiple second privacy pixels 35FG are arranged along the first direction X to form three columns of third privacy pixels 35FBL. Multiple third privacy pixels 35FB are arranged along the first direction X to form at least one column of third privacy pixels 35FBL, for example, multiple third privacy pixels 35FB are arranged along the first direction X to form three columns of third privacy pixels 35FBL.

[0340] Alternatively, the length of the first privacy sub-pixel column 35FRL in the first direction X increases as the distance to the first shared sub-pixel 35XR in the second direction Y decreases, and the length of the first shared sub-pixel 35XR in the first direction X increases as the distance to the first privacy sub-pixel column 35FRL in the second direction Y decreases. Since the fourth direction M intersects with the second direction Y, the first privacy sub-pixel column 35FRL and the first shared sub-pixel 35XR will be located at the corner of the first region 3a1. Setting the length of the first privacy sub-pixel column 35FRL and the first shared sub-pixel 35XR at the corner is shorter, which is beneficial to improving the pixel density.

[0341] The length of the second privacy sub-pixel column 35FGL in the first direction X increases as the distance to the second shared sub-pixel 35XG in the second direction Y decreases, and the length of the second shared sub-pixel 35XG in the first direction X increases as the distance to the second privacy sub-pixel column 35FGL in the second direction Y decreases. Since the fourth direction M intersects with the second direction Y, the second privacy sub-pixel column 35FGL and the second shared sub-pixel 35XG will be located at the corner of the second region 3a2. Setting the length of the second privacy sub-pixel column 35FGL and the second shared sub-pixel 35XG at the corner is shorter, which is beneficial to improving the pixel density.

[0342] The length of the third privacy sub-pixel column 35FBL in the first direction X increases as the distance to the third shared sub-pixel 35XB in the second direction Y decreases, and the length of the third shared sub-pixel 35XB in the first direction X increases as the distance to the third privacy sub-pixel column 35FBL in the second direction Y decreases. Since the fourth direction M intersects with the second direction Y, the third privacy sub-pixel column 35FBL and the third shared sub-pixel 35XB will be located at the corner of the third region 3a3. Setting the length of the third privacy sub-pixel column 35FBL and the third shared sub-pixel 35XB at the corner is shorter, which is beneficial to improving the pixel density.

[0343] The first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular. The diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the diameter of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0344] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0345] With the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB all being 5 μm, the pixel aperture ratio is approximately 17.3%.

[0346] Of course, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can also be set to various shapes described above, or other shapes not described above, which will not be described in detail here. Moreover, the number of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be set as needed, as can the number of the first privacy pixel column 35FRL, the second privacy pixel column 35FGL, and the third privacy pixel column 35FBL.

[0347] Referring to Figures 26–34, in some exemplary embodiments of this disclosure, a first privacy sub-pixel 35FR and a first shared sub-pixel 35XR form a first pixel group 35R; a second privacy sub-pixel 35FG and a second shared sub-pixel 35XG form a second pixel group 35G; and a third privacy sub-pixel 35FB and a third shared sub-pixel 35XB form a third pixel group 35B. The first pixel group 35R and the third pixel group 35B are arranged alternately along the second direction Y to form a first pixel column 35L1, meaning that a third pixel group 35B is disposed between two adjacent first pixel groups 35R, and a first pixel group 35R is disposed between two adjacent third pixel groups 35B. The second pixel group 35G is arranged along the second direction Y to form a second pixel column 35L2. The first pixel column 35L1 and the second pixel column 35L2 are arranged alternately along the first direction X, meaning that a second pixel column 35L2 is disposed between two adjacent first pixel columns 35L1, and a first pixel column 35L1 is disposed between two adjacent second pixel columns 35L2. The gaps between the second pixel group 35G, the first pixel group 35R, and the third pixel group 35B are set relative to each other, so that the second pixel group 35G, the first pixel group 35R, and the third pixel group 35B are all staggered. Moreover, the first pixel group 35R and the third pixel group 35B are also arranged alternately in the first direction X. That is, in the first direction X, a third pixel group 35B is set between two adjacent first pixel groups 35R, and a first pixel group 35R is set between two adjacent third pixel groups 35B.

[0348] This configuration ensures that the number of pixels in the second pixel group 35G is twice that of the first pixel group 35R, and the number of pixels in the second pixel group 35G is also twice that of the third pixel group 35B. This achieves a high PPI (Pixels Per Inch) display through the SPR (Sub-Pixel Rendering) algorithm. The second pixel group 35G can form a pixel with the adjacent first pixel group 35R and third pixel group 35B. Specifically, referring to Figures 27 and 30 (where black indicates illumination), multiple first privacy sub-pixels 35FR, multiple second privacy sub-pixels 35FG, and multiple third privacy sub-pixels 35FB within a thick black dashed frame form a privacy pixel. This allows multiple second privacy sub-pixels 35FG to form a privacy pixel with the multiple first privacy sub-pixels 35FR and multiple third privacy sub-pixels 35FB on either side. The multiple first privacy sub-pixels 35FR and multiple third privacy sub-pixels 35FB are borrowed pixels. Either of the two sets of second privacy sub-pixels 35FG on both sides can be combined for display. Referring to Figures 28 and 31, the black fill indicates that the display is lit. The first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB within a thick black dashed box form a shared pixel. This allows the second shared sub-pixel 35XG to form a shared pixel with the first shared sub-pixels 35XR and the third shared sub-pixels 35XB on both sides. The first shared sub-pixels 35XR and the third shared sub-pixels 35XB are borrowed pixels and can be combined for display with either of the two second shared sub-pixels 35XG on both sides.

[0349] Specifically, as shown in Figure 26, the first shared sub-pixel 35XR can be set as a rounded rectangle, and the length and width of the first shared sub-pixel 35XR are basically the same; the second shared sub-pixel 35XG can be set as a rounded rectangle, and the length and width of the second shared sub-pixel 35XG are basically the same; the third shared sub-pixel 35XB can be set as a rounded square, so that the length and width of the third shared sub-pixel 35XB are the same.

[0350] At least two first privacy sub-pixels 35FR are arranged along the first direction X to form at least one column of first privacy sub-pixels 35FRL. For example, two first privacy sub-pixels 35FR are arranged along the first direction X to form a column of first privacy sub-pixels 35FRL. The first privacy sub-pixel column 35FRL is located between the first shared sub-pixel 35XR and the third shared sub-pixel 35XB.

[0351] Multiple third privacy sub-pixels 35FB are arranged as at least two columns of third privacy sub-pixel columns 35FBL extending along the first direction X. For example, multiple third privacy sub-pixels 35FB are arranged as three columns of third privacy sub-pixel columns 35FBL extending along the first direction X, and the lengths of the three columns of third privacy sub-pixel columns 35FBL are successively smaller in the direction away from the third shared sub-pixel 35XB, such that the three columns of third privacy sub-pixel columns 35FBL surround and form a triangular third privacy region 3aF3; the three columns of third privacy sub-pixel columns 35FBL are located between the first shared sub-pixel 35XR and the third shared sub-pixel 35XB.

[0352] At least two second privacy pixels 35FG are arranged in a column of second privacy pixels 35FGL. Multiple third privacy pixels 35FB surround a region forming a third privacy area 3aF3. The second privacy pixel column 35FGL and the third privacy area 3aF3 are adjacent to and parallel to one edge, that is, the second privacy pixel column 35FGL and the triangular third privacy area 3aF3 are adjacent to and parallel to one edge. This arrangement avoids interference between the second privacy pixel column 35FGL and the third privacy pixel column 35FBL.

[0353] In this case, the pixel density can reach approximately 413 PPI (Pixels Per Inch), which is a significant increase compared to the 150 PPI to 300 PPI structure of the example implementation shown in Figures 6-25.

[0354] Referring to Figure 29, optionally, based on the arrangement in Figure 26, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are all set as rounded rectangles extending along the first direction X. At least one column of third privacy sub-pixel 35FBL is also provided between the third shared sub-pixel 35XB and the first privacy sub-pixel column 35FRL; for example, one, two, or more columns of third privacy sub-pixel 35FBL are provided between the third shared sub-pixel 35XB and the first privacy sub-pixel column 35FRL. The three first privacy sub-pixels 35FR are arranged along the first direction X to form two columns of first privacy sub-pixel 35FRL. A second privacy pixel 35FG is provided on the side of the second privacy sub-pixel column 35FGL away from the third privacy region 3aF3, such that the three second privacy pixels 35FG are arranged to form a triangle.

[0355] In this case, the pixel density can reach approximately 353 PPI (Pixels Per Inch), which is a significant increase compared to the 150 PPI to 300 PPI structure of the example embodiments shown in Figures 6-25. The aperture ratio is increased by 50% compared to the example embodiment shown in Figure 26.

[0356] In the example embodiments shown in Figures 26 and 29, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB are all circular. The diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be greater than or equal to 4μm and less than or equal to 10μm. For example, the diameters of the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm, 9.5μm, etc.

[0357] In this case, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be greater than or equal to 4μm and less than or equal to 8μm. For example, the width of the first shared sub-pixel 35XR, the width of the second shared sub-pixel 35XG, and the width of the third shared sub-pixel 35XB can be 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, etc.

[0358] The aperture ratio of the red, green, and blue subpixels can be 1:2:3, or other ratios.

[0359] Referring to Figures 32-34, the center points of two adjacent first pixel groups 35R and the center points of two adjacent third pixel groups 35B are connected to form a virtual rectangle XJ, and the center point of the second pixel group 35G is located at the center point of the virtual rectangle XJ; specifically, the center points of two adjacent first pixel groups 35R and the center points of two adjacent third pixel groups 35B are connected to form a virtual square, and the center point of the second pixel group 35G is located at the center point of the virtual square.

[0360] Of course, in some other example embodiments of this disclosure, the center points of two adjacent first pixel groups 35R and the center points of two adjacent third pixel groups 35B may be connected to form a dummy rectangle and a dummy rhombus, and the center point of the second pixel group 35G may be located at the center point of the dummy rectangle and the dummy rhombus.

[0361] Referring to Figures 32 and 33, in some exemplary embodiments of this disclosure, a plurality of first privacy sub-pixels 35FR surround the periphery of a first shared sub-pixel 35XR, a plurality of second privacy sub-pixels 35FG surround the periphery of a second shared sub-pixel 35XG, and a plurality of third privacy sub-pixels 35FB surround the periphery of a third shared sub-pixel 35XB.

[0362] Specifically, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB can all be set as squares. Multiple first privacy sub-pixels 35FR are spaced apart and arranged in a square ring around the first shared sub-pixel 35XR. Multiple second privacy sub-pixels 35FG are spaced apart and arranged in a square ring around the second shared sub-pixel 35XG. Multiple third privacy sub-pixels 35FB are spaced apart and arranged in a square ring around the third shared sub-pixel 35XB.

[0363] Of course, in some other exemplary embodiments of this disclosure, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB can all be configured as circles, ellipses, rectangles, etc. In this case, a plurality of first privacy sub-pixels 35FR are spaced apart and arranged to form a circular, elliptical, rectangular, etc. ring around the outer periphery of the first shared sub-pixel 35XR. A plurality of second privacy sub-pixels 35FG are spaced apart and arranged to form a circular, elliptical, rectangular, etc. ring around the outer periphery of the second shared sub-pixel 35XG. A plurality of third privacy sub-pixels 35FB are spaced apart and arranged to form a circular, elliptical, rectangular, etc. ring around the outer periphery of the third shared sub-pixel 35XB.

[0364] Referring to Figure 32, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can all be set to circles. Referring to Figure 33, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can all be set to squares. Of course, the first privacy pixel 35FR, the second privacy pixel 35FG, and the third privacy pixel 35FB can also be set to the various shapes described above, or other shapes not described above, which will not be described in detail here.

[0365] Referring to FIG34, in some exemplary embodiments of this disclosure, the first shared sub-pixel 35XR, the second shared sub-pixel 35XG, and the third shared sub-pixel 35XB are all set as rectangles, and the first shared sub-pixel 35XR extends along the fourth direction M, and the third shared sub-pixel 35XB extends along the fifth direction N; the fourth direction M and the first direction X are provided with a set angle, which is greater than or equal to 30° and less than or equal to 60°. For example, the set angle can be 35°, 40°, 45°, 50°, 55°, etc., and the fifth direction N is set perpendicular to the fourth direction M.

[0366] A plurality of second privacy sub-pixels 35FG are disposed around the second shared sub-pixel 35XG. The plurality of second privacy sub-pixels 35FG are spaced apart and arranged to form a square ring around the second shared sub-pixel 35XG. Of course, in some other exemplary embodiments of this disclosure, the second shared sub-pixel 35XG can be configured as a circle, ellipse, rectangle, etc. In this case, the plurality of second privacy sub-pixels 35FG are spaced apart and arranged to form a circle, ellipse, rectangle, etc., around the outer periphery of the second shared sub-pixel 35XG.

[0367] The first privacy sub-pixel 35FR is located on the side of the first shared sub-pixel 35XR near the second shared sub-pixel 35XG. Specifically, an array of multiple first privacy sub-pixels 35FR is arranged on the side of the first shared sub-pixel 35XR near the second shared sub-pixel 35XG. For example, the multiple first privacy sub-pixels 35FR can be arranged into one, two, or more columns of first privacy sub-pixel columns 35FRL extending along the fourth direction M, and the length of the first privacy sub-pixel column 35FRL in the fourth direction M can be substantially the same as the length of the first shared sub-pixel 35XR in the fourth direction M.

[0368] The third privacy sub-pixel 35FB is located on the side of the third shared sub-pixel 35XB that is close to the second shared sub-pixel 35XG. Specifically, an array of multiple third privacy sub-pixels 35FB is arranged on the side of the third shared sub-pixel 35XB that is close to the second shared sub-pixel 35XG. For example, the multiple third privacy sub-pixels 35FB can be arranged into one, two or more columns of third privacy sub-pixel columns 35FBL extending along the fifth direction N, and the length of the third privacy sub-pixel column 35FBL in the fifth direction N can be substantially the same as the length of the third shared sub-pixel 35XB in the fifth direction N.

[0369] Of course, in some other exemplary embodiments of this disclosure, the first privacy sub-pixel 35FR may be located on the side of the first shared sub-pixel 35XR away from the second shared sub-pixel 35XG, and the third privacy sub-pixel 35FB may be located on the side of the third shared sub-pixel 35XB away from the second shared sub-pixel 35XG.

[0370] In the example implementation shown in Figures 32-34, multiple second privacy pixels 35FG can be combined with multiple first privacy pixels 35FR and multiple third privacy pixels 35FB at the two vertices of the dummy rectangle XJ to form a privacy pixel. The multiple first privacy pixels 35FR and multiple third privacy pixels 35FB are borrowed pixels, and can be combined with any one of the two sets of second privacy pixels 35FG on both sides for display.

[0371] The second shared sub-pixel 35XG can form a shared pixel with the first shared sub-pixel 35XR and the third shared sub-pixel 35XB at the two vertices of the dummy rectangle XJ. The first shared sub-pixel 35XR and the third shared sub-pixel 35XB are borrowed pixels, and can be combined with any one of the two second shared sub-pixels 35XG on both sides for display.

[0372] This configuration allows both the privacy display and the shared display to have green subpixels centered, improving the display effect.

[0373] Referring to FIG35, in some exemplary embodiments of this disclosure, pixel region 3a can be set as a rectangle, for example, pixel region 3a can be set as a square; pixel region 3a can include a middle region 3aZ, a first region 3a1, a second region 3a2, a third region 3a3 and a fourth region 3a4; the middle region 3aZ is located in the middle of pixel region 3a, and the middle region 3aZ can be set as a rectangle, for example, the middle region 3aZ can be set as a square.

[0374] The first region 3a1, the second region 3a2, the third region 3a3, and the fourth region 3a4 are connected end to end in sequence and surround the middle region 3aZ. Specifically, the first region 3a1, the second region 3a2, the third region 3a3, and the fourth region 3a4 are connected end to end in a counterclockwise direction to form a square ring that surrounds the middle region 3aZ. Moreover, the first region 3a1, the second region 3a2, the third region 3a3, and the fourth region 3a4 occupy the four corners of the pixel area 3a one by one, so that the first region 3a1, the second region 3a2, the third region 3a3, and the fourth region 3a4 are all set in an "L" shape, with the first region 3a1 and the third region 3a3 facing each other, and the second region 3a2 and the fourth region 3a4 facing each other.

[0375] Of course, in some other example embodiments of this disclosure, the pixel area 3a can be set as a circle, and the first area 3a1, the second area 3a2, the third area 3a3 and the fourth area 3a4 are connected end to end in a counterclockwise direction to form a ring, surrounding the outer periphery of the middle area 3aZ.

[0376] Both the second region 3a2 and the fourth region 3a4 are provided with a first shared sub-pixel 35XR and a first privacy sub-pixel 35FR. That is, the first shared sub-pixel 35XR and the first privacy sub-pixel 35FR are provided in both the second region 3a2 and the fourth region 3a4. Both the first region 3a1 and the third region 3a3 are provided with a third shared sub-pixel 35XB and a third privacy sub-pixel 35FB. That is, the third shared sub-pixel 35XB and the third privacy sub-pixel 35FB are provided in both the first region 3a1 and the third region 3a3.

[0377] The first shared sub-pixel 35XR and the third shared sub-pixel 35X are arranged alternately in two columns along the second direction Y. Specifically, the third shared sub-pixel 35XB located in the first region 3a1 and the first shared sub-pixel 35XR located in the fourth region 3a4 are arranged alternately in one column along the second direction Y, and the first shared sub-pixel 35XR located in the second region 3a2 and the third shared sub-pixel 35XB located in the third region 3a3 are arranged alternately in one column along the second direction Y.

[0378] Multiple first privacy sub-pixels 35FR are arranged in an array and located on the side of the first shared sub-pixel 35XR near the central region 3aZ. For example, the multiple first privacy sub-pixels 35FR are arranged as four columns of first privacy sub-pixel 35FRL extending along the second direction Y. Multiple third privacy sub-pixels 35FB are arranged in an array and located on the side of the third shared sub-pixel 35XB near the central region 3aZ. For example, the multiple third privacy sub-pixels 35FB are arranged as four columns of third privacy sub-pixel 35FBL extending along the second direction Y.

[0379] The second shared sub-pixel 35XG and the second privacy sub-pixel 35FG are located in the middle region 3aZ; and the second shared sub-pixel 35XG extends along the second direction Y, and a plurality of second privacy sub-pixels 35FG arrays are arranged on opposite sides of the second shared sub-pixel 35XG in the first direction X. For example, the plurality of second privacy sub-pixels 35FG are arranged as four columns of second privacy sub-pixel columns 35FGL extending along the second direction Y, and two columns of second privacy sub-pixel columns 35FGL are provided on one side of the second shared sub-pixel 35XG in the first direction X.

[0380] Of course, in some other exemplary embodiments of this disclosure, the second shared sub-pixel 35XG may extend along the first direction X, and a plurality of second privacy sub-pixels 35FG arrays may be arranged on opposite sides of the second shared sub-pixel 35XG in the second direction Y.

[0381] This configuration allows multiple second privacy pixels 35FG to form a privacy pixel together with multiple third privacy pixels 35FB in the first region 3a1 (or the third region 3a3) and multiple first privacy pixels 35FR in the second region 3a2 (or the fourth region 3a4). The multiple second privacy pixels 35FG are borrowed pixels, and can be combined with any one of the two sets of third privacy pixels 35FB on both sides for display, and can also be combined with any one of the two sets of first privacy pixels 35FR on both sides for display.

[0382] The second shared sub-pixel 35XG can form a shared pixel with the first shared sub-pixel 35XR of the second region 3a2 (or the fourth region 3a4) and the third shared sub-pixel 35XB of the first region 3a1 (or the third region 3a3). The second shared sub-pixel 35XG is a borrowed pixel, and it can be combined with either of the two first shared sub-pixels 35XR on its two sides for display, and at the same time, it can be combined with either of the two third shared sub-pixels 35XB on its two sides for display. Moreover, this allows both the privacy display and the shared display to achieve a centered distribution of green sub-pixels, improving the display effect.

[0383] Furthermore, when two or more columns of first privacy pixel arrays 35FRL are provided, the first privacy pixel 35FR of two adjacent columns of first privacy pixel arrays 35FRL can be staggered. When two or more columns of second privacy pixel arrays 35FGL are provided, the second privacy pixel 35FG of two adjacent columns of second privacy pixel arrays 35FGL can be staggered. When two or more columns of third privacy pixel arrays 35FBL are provided, the third privacy pixel 35FB of two adjacent columns of third privacy pixel arrays 35FBL can be staggered.

[0384] Of course, the first privacy pixel 35FR of the two adjacent columns of the first privacy pixel column 35FRL can also be set relative to each other. The second privacy pixel 35FG of the two adjacent columns of the second privacy pixel column 35FGL can also be set relative to each other. The third privacy pixel 35FB of the two adjacent columns of the third privacy pixel column 35FBL can also be set relative to each other.

[0385] Alternatively, in the example embodiments shown in Figures 20-36, a light adjustment layer 7 and a planarization layer 8 may also be provided. The specific structures and refractive index requirements of the light adjustment layer 7 and the planarization layer 8 have been described in detail above, and therefore will not be repeated here. The light adjustment layer 7 may include a shared protrusion 71 and a privacy protrusion 72. The specific structures of the shared protrusion 71 and the privacy protrusion 72, as well as the correspondence between the shared protrusion 71 and the shared sub-pixel 35X, and the correspondence between the privacy protrusion 72 and the privacy sub-pixel 35F, have been described in detail above, and therefore will not be repeated here.

[0386] Based on the same inventive concept, this disclosure provides a display device that may include the display panel described in any of the above-described embodiments. The specific structure of the display panel has been described in detail above, and therefore will not be repeated here.

[0387] The specific type of display device is not particularly limited; any type of display device commonly used in the field is acceptable, such as mobile devices like mobile phones, wearable devices like watches, VR devices, etc. Those skilled in the art can make the appropriate selection based on the specific purpose of the display device, which will not be elaborated further here.
