Description

Technical Field

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

[0002] OLED (Organic Light-Emitting Diode) displays are widely used due to their advantages such as self-illumination and flexibility. To achieve privacy protection, existing OLED displays use both privacy-protecting and non-privacy-protecting pixels. Privacy protection is achieved by blocking light from the privacy-protecting pixels across a wide viewing angle, combined with different display modes. However, in practical use, it has been found that the transmittance and field of view performance of the display panel decrease.

[0003] Therefore, existing OLED display devices suffer from technical problems such as reduced transmittance and field of view performance of the display panel. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the technical problems of reduced transmittance and field of view performance in existing OLED display devices.

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, the display panel including privacy pixels and non-privacy pixels, the display panel comprising: Substrate; A first light-shielding layer is disposed on one side of the substrate, and the first light-shielding layer includes a first light-shielding portion; A second light-shielding layer is disposed on the side of the first light-shielding layer away from the substrate, and the second light-shielding layer includes a second light-shielding portion; Among them, a plurality of privacy-protecting pixels are arranged along a first direction to form a privacy-protecting pixel row, a plurality of non-privacy-protecting pixels are arranged along the first direction to form a non-privacy-protecting pixel row, and the privacy-protecting pixel row and the non-privacy-protecting pixel row are alternately arranged along a second direction; On the projection of the same plane, in the first direction, the privacy pixel is provided with the first light-blocking part and the second light-blocking part on both sides; in the first direction, the non-privacy pixel is not provided with the first light-blocking part and the second light-blocking part on both sides; the angle between the first direction and the second direction is greater than 0 and less than or equal to 90 degrees.

[0006] According to a second aspect of this application, a display device is provided, the display device including a display panel as described in any of the above embodiments.

[0007] This application provides a display panel and a display device. The display panel can achieve privacy display by providing a first light-blocking part and a second light-blocking part on both sides of the privacy pixel in a first direction. In addition, the first light-blocking part and the second light-blocking part are not provided on both sides of the non-privacy pixel in the first direction, thereby avoiding the decrease in the transmittance of the display panel due to the excessive area of ​​the first light-blocking part and the second light-blocking part, thereby improving the transmittance of the display panel and improving the viewing angle performance of the display panel.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] To illustrate the principle behind the technical problems in this application, some comparative display devices are provided. It should be understood that these comparative display devices are not considered prior art in the embodiments of this application. Figure 1 As shown, the comparison display device 16 includes a privacy unit 142 and a non-privacy unit 141. In normal display mode, both the privacy unit 142 and the non-privacy unit 141 are illuminated. In privacy mode, only the privacy unit 142 is illuminated, achieving privacy display. Figure 1 As shown, the privacy unit 142 includes a red privacy sub-pixel, a green privacy sub-pixel, and a blue privacy sub-pixel, while the non-privacy unit 141 includes a red non-privacy sub-pixel, a green non-privacy sub-pixel, and a blue non-privacy sub-pixel.

[0021] In terms of membrane structure, such as Figure 1 As shown in (a), a contrast display device has a first black matrix film 151 around both the privacy sub-pixel and the non-privacy sub-pixel, and a second black matrix film 152 around the privacy sub-pixel. The first black matrix film 151 and the second black matrix film 152 are slightly extended outward relative to the pixel definition film 153. The first black matrix film 151 controls the light emission angle of the non-privacy unit 141, and the first black matrix film 151 and the second black matrix film 152 block the light from the privacy unit 142 at a wide viewing angle, achieving 360-degree omnidirectional privacy. Figure 2 As shown, the privacy mode can be entered from four positions: the top 161, the bottom 162, the left 163, and the right 164 of the display device 16.

[0022] like Figure 1 As shown in (b), another contrast display device has a first black matrix film 151 on both sides of the privacy sub-pixel and the non-privacy sub-pixel, and a second black matrix film 152 on both sides of the privacy sub-pixel. The first black matrix film 151 controls the light emission angle of the non-privacy unit 141, while the first black matrix film 151 and the second black matrix film 152 block light from the privacy unit 142 at both wide and large viewing angles. Figure 2 As shown, the comparison display device can achieve privacy protection for the left side 163 and the right side 164.

[0023] However, in actual use, such as Figure 1 As shown, it was found that regardless of whether it is 360-degree omnidirectional privacy protection or lateral privacy protection, a first black matrix film 151 is set on both sides of the non-privacy-protected sub-pixels. This first black matrix film 151 blocks light, leading to a decrease in the transmittance and FOV (Field of View) performance of the display device. Furthermore, the first black matrix film 151 on both sides of the non-privacy-protected sub-pixels will significantly increase the brightness attenuation in the normal display mode of the display device. Therefore, existing OLED display devices suffer from technical problems related to reduced transmittance and FOV performance of the display panel.

[0024] This application provides a display panel and a display device to address the aforementioned technical problems.

[0025] like Figure 3 As shown, this application embodiment provides a display panel 1, which includes a display area 101 and a non-display area 102. Sub-pixels can be set in the display area 101, and structures such as gate driving circuits and bonding terminals can be set in the non-display area 102.

[0026] Specifically, Figure 1 The example described uses a non-display area 102 surrounding a display area 101, but this embodiment is not limited to this. The non-display area 102 can be located on one, two, or three sides of the display area 101. Furthermore, when the display panel in this embodiment needs to accommodate under-display sensors (e.g., an under-display camera), the display panel can also have a punch-hole area within the display area 101, which may or may not be displayed. When the display panel in this embodiment uses a full-screen display, the non-display area 102 can be bent or folded to the back of the display panel 1.

[0027] Specifically, the non-display area 102 may include a left border area, a right border area, an upper border area, and a lower border area respectively disposed on the left, right, upper, and lower sides of the display area 101. Gate driving circuits may be disposed in the left and right border areas to input signals, and bonding terminals may be disposed in the lower border area for bonding driving chips. The lower border area includes a bonding area 102a.

[0028] Specifically, such as Figure 3 , Figure 6 , Figure 7 As shown, the display area 101 is provided with multiple non-peeping pixels 11 and peeping pixels 12. The non-peeping pixels 11 may include a first non-peeping sub-pixel 111, a second non-peeping pixel 112 and a third non-peeping pixel 113 with different light emission colors. The peeping pixels 12 may include a first peeping sub-pixel 121, a second peeping pixel 122 and a third peeping pixel 123 with different light emission colors.

[0029] Specifically, the emission color of one of the first non-peeping sub-pixels 111, the second non-peeping sub-pixels 112, and the third non-peeping sub-pixels 113 is one of red, green, and blue; the emission color of another of the first non-peeping sub-pixels 111, the second non-peeping sub-pixels 112, and the third non-peeping sub-pixels 113 is one of red, green, and blue; and the emission color of the remaining one of the first non-peeping sub-pixels 111, the second non-peeping sub-pixels 112, and the third non-peeping sub-pixels 113 is the remaining one of red, green, and blue. For example, the emission colors of the first non-peeping sub-pixels 111, the second non-peeping sub-pixels 112, and the third non-peeping sub-pixels 113 are red, green, or blue, respectively. Of course, the emission colors of the first non-peeping sub-pixels 111, the second non-peeping sub-pixels 112, and the third non-peeping sub-pixels 113 can be other combinations, which will not be elaborated here.

[0030] Specifically, one of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 emits light in a color that is one of red, green, and blue; another of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 emits light in a color that is one of red, green, and blue; and the remaining one of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 emits light in a color that is one of red, green, and blue. For example, the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 emit light in a color that is red, green, or blue, respectively. Of course, the light emission colors of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 can be other combinations, which will not be elaborated here.

[0031] Specifically, the emission colors of the first non-peeping sub-pixel 111, the second non-peeping sub-pixel 112, and the third non-peeping sub-pixel 113 can be the same as those of the first privacy sub-pixel 121, the second privacy sub-pixel 122, and the third privacy sub-pixel 123, respectively.

[0032] Specifically, by making the light emission colors of the first non-peeping sub-pixel 111, the second non-peeping sub-pixel 112, and the third non-peeping sub-pixel 113 different, the light emission colors of the light-emitting parts corresponding to each non-peeping sub-pixel can be different. Similarly, by making the light emission colors of the first privacy sub-pixel 121, the second privacy sub-pixel 122, and the third privacy sub-pixel 123 different, the light emission colors of the light-emitting parts corresponding to each privacy sub-pixel can be different.

[0033] Specifically, the arrangement of sub-pixels in non-spy pixel 11 and spy pixel 12 is not limited in this embodiment. The following embodiments use realRGB as an example for illustration.

[0034] Specifically, the arrangement of the non-spy pixel 11 and the spy pixel 12 is not limited in this application embodiment. In the following embodiment, some arrangement of the non-spy pixel 11 and the spy pixel 12 will be used as examples for illustration.

[0035] Specifically, such as Figure 4 , Figure 5 , Figure 8 As shown, the display panel 1 includes a substrate 21, a driving circuit layer 22, a light-emitting functional layer 25, and an encapsulation layer 26. The driving circuit layer 22 is disposed on one side of the substrate 21, the light-emitting functional layer 25 is disposed on the side of the driving circuit layer 22 away from the substrate 21, and the encapsulation layer 26 is disposed on the side of the light-emitting functional layer 25 away from the driving circuit layer 22.

[0036] Specifically, such as Figure 4 , Figure 5 , Figure 8 As shown, the display panel 1 also includes a touch layer 27, which is disposed on the side of the encapsulation layer 26 away from the light-emitting functional layer 25.

[0037] Specifically, the display panel 1 may also include a dimming function layer, which is located on the side of the touch layer away from the encapsulation layer.

[0038] Specifically, the dimming function layer may include a first microlens layer and a second microlens layer. The refractive index of the second microlens layer is greater than that of the first microlens layer. The first microlens layer is disposed between the touch layer and the second microlens layer. The first microlens layer has an opening in the region of the corresponding sub-pixel, and the second microlens layer is disposed within the opening.

[0039] Specifically, the refractive index of the first microlens layer ranges from 1.45 to 1.55, and the refractive index of the second microlens layer ranges from 1.6 to 1.8.

[0040] Specifically, such as Figure 4 , Figure 5 As shown, the display panel 1 also includes a first flattening layer 28, a first light-shielding layer 291, a second flattening layer 292, a third flattening layer 293, a second light-shielding layer 294, and a fourth flattening layer 295 arranged sequentially.

[0041] Specifically, the materials of the first light-shielding layer 291 and the second light-shielding layer 294 can be black photoresist, that is, the first light-shielding layer 291 and the second light-shielding layer 294 can be black matrix layers.

[0042] Specifically, the first planarization layer 28 can serve as the first microlens layer.

[0043] Specifically, the display panel 1 may also include a third light-shielding layer and a color resist layer, which may be disposed between the touch layer 27 and the first planarization layer 28.

[0044] Specifically, the material of the third light-shielding layer can be black photoresist, that is, the third light-shielding layer can be a black matrix layer.

[0045] Specifically, such as Figure 8 As shown, the driving circuit layer 22 includes a first barrier layer 221, a light-shielding layer 222, a second barrier layer 223, a buffer layer 224, an active layer 225, a first gate insulating layer 226, a first gate layer 227, a second gate insulating layer 228, a second gate layer 229, a first interlayer insulating layer 231, a semiconductor layer 232, a third gate insulating layer 233, a third gate layer 234, a second interlayer insulating layer 235, a first source-drain layer 236, a first planarization layer 237, a second source-drain layer 238, and a second planarization layer 242.

[0046] Specifically, the active layer can be made of silicon semiconductor, and the semiconductor layer can be made of oxide semiconductor.

[0047] Specifically, Figure 8 The driving circuit layer 22 shown in the illustration is illustrated with an example of an active layer, a semiconductor layer, three gate layers, and two source / drain layers arranged sequentially. However, the embodiments of this application are not limited to this. For example, the driving circuit layer 22 may have one or two gate layers. When two gate layers are present, they may be disposed on opposite sides of the active layer or on the same side of the active layer. One gate layer forms a gate, and the other forms a capacitor and / or a signal line. Alternatively, the driving circuit layer 22 may include one active layer, and may also have one or three source / drain layers. The film structure of the driving circuit layer 22 described in this application embodiment is merely an example. The structure of the driving circuit layer 22 in this application embodiment may also be other structures, which will not be elaborated here.

[0048] Specifically, such as Figure 8 As shown, the light-emitting functional layer 25 includes a pixel electrode layer 251, a pixel definition layer 252, a light-emitting material layer 253, and a common electrode layer 254.

[0049] Specifically, the pixel definition layer 252 may consist of only one film layer, which may be a transparent material or contain a light-blocking material; or the pixel definition layer 252 may consist of two film layers. For example, the pixel definition layer 252 may include a first pixel definition layer and a second pixel definition layer, where the light transmittance of the first pixel definition layer is greater than that of the second pixel definition layer. Both the first and second pixel definition layers are formed using light-transmitting photoresist, the difference being that the second pixel definition layer contains a light-blocking material. The hydrophilicity of the first pixel definition layer may be greater than that of the second pixel definition layer. The positions of the first and second pixel definition layers can be set according to requirements.

[0050] Specifically, when the material of the pixel definition layer 252 contains a light-shielding material, a third light-shielding layer and a color resist layer can be used; when the material of the pixel definition layer 252 is a transparent material, a polarizer can be used to reduce reflection.

[0051] Specifically, such as Figure 4 , Figure 5 As shown, the encapsulation layer 26 includes a first inorganic encapsulation layer 261, an organic layer 262, and a second inorganic encapsulation layer 263.

[0052] Specifically, such as Figure 8 As shown, the touch layer 27 includes a first touch insulating layer 271, a first touch metal layer 272, a second touch insulating layer 273, and a second touch metal layer 274. However, the embodiments of this application are not limited to this. The number of touch metal layers and touch insulating layers can be other numbers, and the order of the film layers of touch metal layers and touch insulating layers can be other orders. For example, the touch layer 27 may also include a third touch insulating layer, which is disposed on the second touch metal layer 274.

[0053] Specifically, the pixel definition layer 252 includes multiple openings corresponding to the first non-peeping pixel 111, the second non-peeping pixel 112, and the third non-peeping pixel 113, respectively, and the area of ​​each opening may be the same or different.

[0054] Specifically, the pixel definition layer 252 includes multiple openings corresponding to the first privacy sub-pixel 121, the second privacy sub-pixel 122, and the third privacy sub-pixel 123, respectively. The area of ​​each opening can be the same or different. The width of each opening in the first direction can be made similar, thereby ensuring that the JNCD (Just Noticeable Color Difference, used to characterize color difference) of the privacy pixels under different viewing angles is similar or even the same.

[0055] Specifically, the opening in pixel definition layer 252 corresponding to the first non-peeping pixel 111 can have the same area as the opening in pixel definition layer 252 corresponding to the first peeping pixel 121. The opening in pixel definition layer 252 corresponding to the second non-peeping pixel 112 can have the same area as the opening in pixel definition layer 252 corresponding to the second peeping pixel 122. The opening in pixel definition layer 252 corresponding to the third non-peeping pixel 113 can have the same area as the opening in pixel definition layer 252 corresponding to the third peeping pixel 123.

[0056] In some embodiments, when the display panel 1 is configured in sharing mode, both the non-spy pixel 11 and the privacy pixel 12 emit light; when the display panel 1 is configured in privacy mode, the non-spy pixel 11 does not emit light, and the privacy pixel 12 emits light.

[0057] In some embodiments, in the first direction X, at a viewing angle of 30 degrees to 45 degrees, the brightness of the privacy pixel 12 is 1% to 10% of the brightness of the normal viewing angle (which can be considered as a 0-degree viewing angle); at a viewing angle of 60 degrees, the brightness of the non-privacy pixel 11 is 20% to 30% of the brightness of the normal viewing angle (which can be considered as a 0-degree viewing angle).

[0058] like Figures 3 to 8 As shown, this application embodiment provides a display panel 1, which includes privacy pixels 12 and non-privacy pixels 11. A plurality of privacy pixels 12 are arranged along a first direction X to form a privacy pixel row 32, and a plurality of non-privacy pixels 11 are arranged along the first direction X to form a non-privacy pixel row 31. The privacy pixel row 32 and the non-privacy pixel row 31 are alternately arranged along a second direction Y.

[0059] This application provides a display panel 1 in which multiple privacy pixels 12 are arranged in the same row and multiple non-privacy pixels 11 are arranged in another row. When a light-shielding structure is set to block light, the light-shielding structure does not need to be set between the non-privacy pixels, thereby reducing the area of ​​the light-shielding structure, improving the transmittance of the display panel, and improving the viewing angle performance of the display panel.

[0060] like Figures 3 to 8 As shown, this application embodiment provides a display panel 1, which includes privacy pixels 12 and non-privacy pixels 11. The display panel 1 includes a substrate 21, a first light-shielding layer 291 and a second light-shielding layer 294. The first light-shielding layer 291 is disposed on one side of the substrate 21 and includes a first light-shielding portion 291a. The second light-shielding layer 294 is disposed on the side of the first light-shielding layer 291 away from the first light-shielding layer 291 and includes a second light-shielding portion 294a. Among them, a plurality of privacy pixels 12 are arranged along the first direction X to form a privacy pixel row 32, a plurality of non-privacy pixels 11 are arranged along the first direction X to form a non-privacy pixel row 31, and the privacy pixel row 32 and the non-privacy pixel row 31 are alternately arranged along the second direction Y. On the same plane, in the first direction X, the privacy pixel 12 is provided with the first light-blocking part 291a and the second light-blocking part 294a on both sides; in the first direction X, the non-privacy pixel 11 is not provided with the first light-blocking part 291a and the second light-blocking part 294a on both sides; the angle between the first direction X and the second direction Y is greater than 0 and less than or equal to 90 degrees.

[0061] This application provides a display panel; the display panel 1 has a first light-blocking part 291a and a second light-blocking part 294a on both sides of the privacy pixel 12 in the first direction X, thereby achieving privacy display of the display panel. In addition, the first light-blocking part 291a and the second light-blocking part 294a are not provided on both sides of the non-privacy pixel 11 in the first direction X, thereby avoiding the decrease in the transmittance of the display panel due to the excessive area of ​​the first light-blocking part 291a and the second light-blocking part 294a, thereby improving the transmittance of the display panel and improving the viewing angle performance of the display panel.

[0062] Specifically, compared to the comparison display device, since privacy pixels and non-privacy pixels are arranged alternately in the horizontal and vertical directions, in order to balance the brightness symmetry of the second light-shielding part 294a on both sides of the privacy pixel with respect to the non-privacy pixel, a first light-shielding part is added between the non-privacy pixels to block light. However, this will lead to an increase in the area of ​​the light-shielding part, a decrease in the transmittance of the display panel, a decrease in FOV performance, and a significant increase in brightness attenuation in normal display mode.

[0063] In this embodiment, since neither the first light-shielding part 291a nor the second light-shielding part 294a is provided on both sides of the non-peeping pixel 11, the space occupied by the light-shielding part can be reduced, the transmittance of the display panel can be improved, and the FOV performance can be improved. Also, since neither the first light-shielding part 291a nor the second light-shielding part 294a is provided on both sides of the non-peeping pixel 11, the brightness decay of the display panel will be slower in the sharing mode. And since both sides of the privacy pixel 12 are provided with the first light-shielding part 291a and the second light-shielding part 294a, the privacy effect can still be achieved.

[0064] Specifically, since the pixels are formed by light-emitting functional layers, the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting functional layer 25 are different film layers located on different planes in the thickness direction of the display panel. Therefore, when explaining the positional relationship between the first light-shielding layer 291, the second light-shielding layer 294, and the pixels in the first direction X and the second direction Y, it is necessary to ensure that the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting functional layer 25 are located on the same plane. Therefore, the relative positions of the structures of each film layer can be explained based on the projection of the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting functional layer 25 onto the same plane.

[0065] Understandably, this plane can be the plane where the substrate is located, the ground, or other films or interfaces.

[0066] Specifically, regarding the projection onto the same plane, in the first direction X, the privacy pixel has a first light-blocking part 291a and a second light-blocking part 294a on both sides. That is, in the first direction X, the projection of the light-emitting part corresponding to the privacy pixel onto a plane has the first light-blocking part 291a and the second light-blocking part 294a projected onto the same plane on both sides. Similarly, the meaning of other relative positions can be determined, which will not be elaborated here.

[0067] Specifically, in the following embodiments, when different structures are located in different film layers, the relative positions of multiple structures in the first direction X and the second direction Y are described based on their projections onto the same plane, and will not be repeated in the following embodiments.

[0068] In some embodiments, such as Figure 3 , Figure 7 As shown, in the second direction Y, neither the first light-blocking part 291a nor the second light-blocking part 294a is provided on either side of the privacy pixel 12 and the non-privacy pixel 11. The first light-blocking part 291a and the second light-blocking part 294a extend along the second direction Y; thus, the vertical direction of the display panel is not blocked, improving the display effect of the display panel.

[0069] In some embodiments, such as Figure 3 , Figure 7 As shown, the display panel 1 also includes a bonding area 102a, which is disposed on one side of the display panel 1 along the second direction Y, so that the non-peeping pixel 11 does not have a first light-blocking part 291a and a second light-blocking part 294a on the upper and lower sides, thereby slowing down the brightness decay of the upper and lower sides of the display panel, improving the transmittance of the display panel, and improving the viewing angle performance of the display panel.

[0070] Specifically, during the use of the display panel, privacy protection mainly targets the left and right sides. Therefore, when privacy protection is designed in a certain direction in a comparative display device, a first light-blocking part is set on the left and right sides of the non-privacy pixel. However, in the embodiment of this application, the first light-blocking part 291a and the second light-blocking part 294a are not set on the sides of the non-privacy pixel 11 in the first direction, thereby slowing down the brightness decay of the left and right sides of the display panel, improving the transmittance of the display panel, and improving the viewing angle performance of the display panel.

[0071] Specifically, such as Figure 3 , Figure 7 As shown, in the second direction Y, neither the first light-blocking part 291a nor the second light-blocking part 294a is provided on either side of the privacy pixel 12, so that the sides that do not need privacy are not blocked by the first light-blocking part and the second light-blocking part, reducing the brightness attenuation of the privacy pixel and improving the display effect.

[0072] Specifically, such as Figure 3 , Figure 7 As shown, in the second direction Y, neither the first light-blocking part 291a nor the second light-blocking part 294a is provided on either side of the non-peeping pixel 11, so that the sides that do not need to be protected from peeping are not blocked by the first light-blocking part and the second light-blocking part, reducing the brightness attenuation of the non-peeping pixel and improving the display effect.

[0073] Specifically, in the actual use of the display panel, the privacy protection of the display panel mainly targets the left and right sides. Since the top and bottom sides of the display panel are tilted at a certain angle when held, privacy protection is often not required for the top and bottom sides of the display panel. Therefore, in this embodiment, by ensuring that the first light-blocking part 291a and the second light-blocking part 294a are not provided on both sides of the privacy pixel and the non-privacy pixel in the second direction Y, privacy protection is not required for the top and bottom sides of the display panel, thereby improving the display effect without affecting the privacy protection function.

[0074] In some embodiments, such as Figure 7 As shown, the privacy pixel 12 includes a first privacy sub-pixel 121, a second privacy sub-pixel 122, and a third privacy sub-pixel 123 with different light-emitting colors. The first privacy sub-pixel 121 and the third privacy sub-pixel 123 are alternately arranged along a first direction X, and the first privacy sub-pixel 121 and the second privacy sub-pixel 122 are alternately arranged along a second direction Y. This allows the privacy pixel 12 to be arranged repeatedly in the first direction, thereby improving the transmittance and field of view performance of the display panel and reducing the brightness attenuation in the sharing mode of the display panel by adjusting the setting positions of the first light-blocking part 291a and the second light-blocking part 294a.

[0075] In some embodiments, such as Figure 7As shown, the non-privacy pixel 11 includes a first non-privacy sub-pixel 111, a second non-privacy sub-pixel 112, and a third non-privacy pixel 113 with different emitting colors. The first non-privacy sub-pixel 111 and the third non-privacy sub-pixel 113 are alternately arranged along a first direction X, and the first non-privacy sub-pixel 111 and the second non-privacy sub-pixel 112 are alternately arranged along a second direction Y. This allows the non-privacy pixel 11 to be repeatedly arranged in the first direction, and by adjusting the positions of the first light-blocking part 291a and the second light-blocking part 294a, the transmittance and field of view performance of the display panel can be improved, and the brightness attenuation in the sharing mode of the display panel can be reduced.

[0076] In some embodiments, such as Figure 7 As shown, in two adjacent rows of privacy pixels 12, the distance between the third privacy sub-pixel 123 and the third non-privacy sub-pixel 113 in one row of privacy pixels 12 is greater than the distance between the third privacy pixel 123 and the third non-privacy sub-pixel 113 in the other row of privacy pixels 12; thus, space can be reserved to set up structures such as support columns.

[0077] Specifically, the spacing between the third privacy sub-pixel 123 and the third non-privacy sub-pixel 113 in one row of privacy pixels 12 can be equal to the spacing between the third privacy sub-pixel 123 and the third non-privacy sub-pixel 113 in another row of privacy pixels 12.

[0078] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the width of the plurality of first light-blocking portions 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 is equal in the second direction Y; so that the privacy effect on both sides of the privacy sub-pixel is similar or even the same, thereby achieving brightness symmetry.

[0079] Specifically, the widths of the multiple first light-blocking portions 291a located between the first privacy pixel 121 and the third privacy pixel 123 can be unequal in the second direction Y.

[0080] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the width of the plurality of first light-blocking portions 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 is equal in the first direction X; so that the privacy effect on both sides of the privacy sub-pixel is similar or even the same, thereby achieving brightness symmetry.

[0081] Specifically, the widths of the multiple first light-blocking portions 291a located between the first privacy pixel 121 and the third privacy pixel 123 can be unequal in the first direction X.

[0082] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the widths of the multiple second light-blocking portions 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 are equal in the second direction Y; this makes the privacy protection effects on both sides of the privacy sub-pixel similar or even the same, thereby achieving brightness symmetry.

[0083] Specifically, the widths of the multiple second light-blocking portions 294a located between the first privacy pixel 121 and the third privacy pixel 123 can be unequal in the second direction Y.

[0084] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the width of the plurality of second light-blocking portions 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 is equal in the first direction X; so that the privacy effect on both sides of the privacy sub-pixel is similar or even the same, thereby achieving brightness symmetry.

[0085] Specifically, the widths of the multiple second light-blocking portions 294a located between the first privacy pixel 121 and the third privacy pixel 123 can be unequal in the first direction X.

[0086] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the first light-shielding part 291a and the first privacy pixel 121 is equal to the distance between the first light-shielding part 291a and the third privacy pixel 123, so that the light-shielding part 291a has a similar or even the same blocking effect on the light emitted by privacy pixels of different light-emitting colors, thereby improving brightness uniformity.

[0087] Specifically, the distance between the first light-blocking part 291a and the first privacy pixel 121 can be different from the distance between the first light-blocking part 291a and the third privacy pixel 123.

[0088] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the first light-shielding part 291a and the second privacy pixel 122 is equal to the distance between the first light-shielding part 291a and the third privacy pixel 123, so that the blocking effect of the first light-shielding part 291a on the light emitted by privacy pixels of different light-emitting colors is similar or even the same, thereby improving the brightness uniformity.

[0089] Specifically, the distance between the first light-blocking part 291a and the second privacy pixel 122 can be different from the distance between the first light-blocking part 291a and the third privacy pixel 123.

[0090] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the first light-shielding part 291a and the first privacy pixel 121 is equal to the distance between the first light-shielding part 291a and the second privacy pixel 122, so that the light-shielding part 291a has a similar or even the same blocking effect on the light emitted by privacy pixels of different light-emitting colors, thereby improving the brightness uniformity.

[0091] Specifically, two or three of the following can be made different: the distance between the first light-blocking part 291a and the first privacy pixel 121, the distance between the first light-blocking part 291a and the second privacy pixel 122, and the distance between the first light-blocking part 291a and the third privacy pixel 123.

[0092] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the spacing between the first privacy pixel 121 of the second light-shielding part 294a is equal to the spacing between the second light-shielding part 294a and the third privacy pixel 123, so that the blocking effect of the second light-shielding part 294a on the light emitted by privacy pixels of different light-emitting colors is similar or even the same, thereby improving the brightness uniformity.

[0093] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the second light-shielding part 294a and the second privacy pixel 122 is equal to the distance between the second light-shielding part 294a and the third privacy pixel 123, so that the blocking effect of the second light-shielding part 294a on the light emitted by privacy pixels of different light-emitting colors is similar or even the same, thereby improving the brightness uniformity.

[0094] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the second light-shielding part 294a and the first privacy pixel 121 is equal to the distance between the second light-shielding part 294a and the second privacy pixel 122, so that the blocking effect of the second light-shielding part 294a on the light emitted by privacy pixels of different light-emitting colors is similar or even the same, thereby improving the brightness uniformity.

[0095] Specifically, the spacing between the second light-blocking part 294a and the first privacy pixel 121, the spacing between the second light-blocking part 294a and the second privacy pixel 122, and the spacing between the second light-blocking part 294a and the third privacy pixel 123 can be different for two or three of them.

[0096] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the first privacy pixel 121 and the first light-blocking portions 291a on both sides is equal, so that the light-blocking effect on both sides of the first privacy pixel 121 is similar or even the same, thereby improving the display symmetry.

[0097] Specifically, the first privacy pixel 121 can be symmetrically arranged with the first light-blocking portions 291a on both sides.

[0098] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the second privacy pixel 122 and the first light-blocking portion 291a on both sides is equal, so that the light-blocking effect on both sides of the second privacy pixel 122 is similar or even the same, thereby improving the display symmetry.

[0099] Specifically, the second privacy pixel 122 can be symmetrically arranged with the first light-blocking portions 291a on both sides.

[0100] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the third privacy pixel 123 and the first light-blocking part 291a on both sides is equal, so that the light-blocking effect on both sides of the third privacy pixel 123 is similar or even the same, thereby improving the display symmetry.

[0101] Specifically, the third privacy pixel 123 can be symmetrically arranged with the first light-blocking portions 291a on both sides.

[0102] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the first privacy pixel 121 and the second light-shielding part 294a on both sides is equal, so that the light emitted from both sides of the first privacy pixel 121 is blocked in a similar or even the same way, thereby improving the display symmetry.

[0103] Specifically, the first privacy pixel 121 can be symmetrically arranged with the second light-blocking portions 294a on both sides.

[0104] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the second privacy pixel 122 and the second light-shielding portions 294a on both sides is equal, so that the light-shielding effect on both sides of the second privacy pixel 122 is similar or even the same, thereby improving the display symmetry.

[0105] Specifically, the second privacy pixel 122 can be symmetrically arranged with the second light-shielding parts 294a on both sides.

[0106] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the first direction X, the distance between the third privacy pixel 123 and the second light-shielding part 294a on both sides is equal, so that the light-shielding effect on both sides of the third privacy pixel 123 is similar or even the same, thereby improving the display symmetry.

[0107] Specifically, the third privacy pixel 123 can be symmetrically arranged with the second light-shielding parts 294a on both sides.

[0108] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the projection of the first light-shielding part 291a on the substrate 21 coincides with the projection of the second light-shielding part 294a on the substrate 21, thereby reducing the space occupied by the first light-shielding part 291a and the second light-shielding part 294a and improving the transmittance of the display panel.

[0109] Specifically, considering that the first light-shielding part 291a and the second light-shielding part 294a may be offset due to process deviations during the actual manufacturing process, it is still assumed that the projection of the first light-shielding part 291a on the substrate 21 coincides with the projection of the second light-shielding part 294a on the substrate 21.

[0110] Specifically, Figure 3 , Figure 6 , Figure 7 The example given is that the projection of the first light-shielding part 291a on the substrate 21 coincides with the projection of the second light-shielding part 294a on the substrate 21, thereby reducing the space occupied by the first light-shielding part 291a and the second light-shielding part 294a and improving the transmittance of the display panel; however, the embodiments of this application are not limited to this.

[0111] In some embodiments, the projection of the first light-shielding part 291a on the substrate 21 does not coincide with the projection of the second light-shielding part 294a on the substrate 21, thereby preventing process deviations from causing the light-shielding part to block the forward light emission and improving the brightness of the display panel.

[0112] Specifically, the distance between the second light-shielding part 294a and the light-emitting part of the privacy pixel can be made greater than the distance between the first light-shielding part 291a and the light-emitting part of the non-privacy pixel; thereby avoiding the offset of the second light-shielding part 294a during the manufacturing process, which would block the light at the front viewing angle or a small angle, and improve the front viewing brightness of the display panel.

[0113] Specifically, the distance between the second light-shielding part 294a and the light-emitting part of the privacy pixel can be made smaller than the distance between the first light-shielding part 291a and the light-emitting part of the non-privacy pixel.

[0114] In some embodiments, such as Figure 7 As shown, the first light-shielding portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a notch on the side facing the first non-privacy sub-pixel 111, thereby preventing the first light-shielding portion 291a from blocking the non-privacy sub-pixel, reducing the area of ​​the first light-shielding portion, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0115] Specifically, such as Figure 7 As shown, the oblique light emission of the first non-privacy pixel 111 may be affected by the first light-blocking portion 291a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the first light-blocking portion 291a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the first non-privacy pixel 111 to reduce the obstruction of the light emission of the first non-privacy pixel 111 by the first light-blocking portion 291a and improve the display effect of the display panel.

[0116] In some embodiments, such as Figure 7 As shown, the first light-shielding portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a notch on the side facing the second non-privacy sub-pixel 112, thereby preventing the first light-shielding portion 291a from blocking the light of the second non-privacy sub-pixel, reducing the area of ​​the first light-shielding portion, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the second non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0117] Specifically, such as Figure 7As shown, the oblique light emission of the second non-privacy pixel 112 may be affected by the first light-blocking portion 291a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the first light-blocking portion 291a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the second non-privacy pixel 112 to reduce the obstruction of the light emission of the second non-privacy pixel 112 by the first light-blocking portion 291a and improve the display effect of the display panel.

[0118] In some embodiments, such as Figure 7 As shown, the first light-shielding portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a notch on the side facing the third non-privacy sub-pixel 113, thereby preventing the first light-shielding portion 291a from blocking the light of the third non-privacy sub-pixel 113, reducing the area of ​​the first light-shielding portion, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the third non-privacy sub-pixel 113 similar or even the same at different angles, improving the brightness symmetry of different directions.

[0119] Specifically, such as Figure 7 As shown, the oblique light emission of the third non-privacy pixel 113 may be affected by the first light-blocking portion 291a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the first light-blocking portion 291a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the third non-privacy pixel 113 to reduce the obstruction of the light emission of the third non-privacy pixel 113 by the first light-blocking portion 291a and improve the display effect of the display panel.

[0120] In some embodiments, such as Figure 7 As shown, the second light-shielding portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a notch on the side facing the first non-privacy sub-pixel 111, thereby preventing the second light-shielding portion 294a from blocking the non-privacy sub-pixel, reducing the area of ​​the second light-shielding portion 294a, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0121] Specifically, such as Figure 7As shown, the oblique light emission of the first non-privacy pixel 111 may be affected by the second light-shielding part 294a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the second light-shielding part 294a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the first non-privacy pixel 111 to reduce the obstruction of the light emission of the first non-privacy pixel 111 by the second light-shielding part 294a and improve the display effect of the display panel.

[0122] In some embodiments, such as Figure 7 As shown, the second light-shielding portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a notch on the side facing the second non-privacy sub-pixel 112, thereby preventing the second light-shielding portion 294a from blocking the light of the second non-privacy sub-pixel, reducing the area of ​​the second light-shielding portion 294a, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the second non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0123] Specifically, such as Figure 7 As shown, the oblique light emission of the second non-privacy pixel 112 may be affected by the second light-shielding portion 294a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the second light-shielding portion 294a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the second non-privacy pixel 112 to reduce the obstruction of the light emission of the second non-privacy pixel 112 by the second light-shielding portion 294a and improve the display effect of the display panel.

[0124] In some embodiments, such as Figure 7 As shown, the second light-shielding portion 294a located between the first privacy pixel 121 and the third privacy pixel 123 has a notch on the side facing the third non-privacy pixel 113, thereby preventing the second light-shielding portion 294a from blocking the light of the third non-privacy pixel 113, reducing the area of ​​the second light-shielding portion 294a, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the third non-privacy pixel 113 similar or even the same at different angles, improving the brightness symmetry of different directions.

[0125] Specifically, such as Figure 7As shown, the oblique light emission of the third non-privacy pixel 113 may be affected by the second light-shielding portion 294a between the first privacy pixel 121 and the third privacy pixel 123. Therefore, the second light-shielding portion 294a located between the first privacy pixel 121 and the third privacy pixel 123 can be provided with a notch on the side facing the third non-privacy pixel 113 to reduce the obstruction of the light emission of the third non-privacy pixel 113 by the second light-shielding portion 294a and improve the display effect of the display panel.

[0126] In some embodiments, such as Figure 3 , Figure 6 As shown, each of the privacy pixels 12 includes a first privacy sub-pixel 121, a second privacy sub-pixel 122, and a third privacy sub-pixel 123 of different luminous colors. Two privacy pixels 12 form a privacy repeating unit 12a. In the privacy repeating unit 12a, the first privacy sub-pixel 121 and the second privacy sub-pixel 122 are arranged along the second direction Y, one third privacy sub-pixel 123 is sandwiched between two first privacy pixels 121 along the first direction X, and another third privacy pixel 123 is sandwiched between two second privacy pixels 122 along the first direction X. This allows the positions of the privacy sub-pixels and non-privacy sub-pixels to be adjusted, reducing the overlap area between the light-blocking part and the light-transmitting hole, thereby increasing the light-transmitting area of ​​the light-transmitting hole and further improving the transmittance of the display panel.

[0127] Specifically, compared to current display devices, the overlap area between the first light-blocking portion 291a and the second light-blocking portion 294a and the light-transmitting hole is relatively large, resulting in a smaller light-transmitting area and lower transmittance of the display panel. In this embodiment, by arranging one third privacy pixel 123 opposite to the first privacy pixel 121 along the first direction X, and another third privacy pixel 123 opposite to the second privacy pixel 122 along the first direction X, the overlap area between the first light-blocking portion 291a and the second light-blocking portion 294a and the light-transmitting hole can be reduced, thereby increasing the light-transmitting area of ​​the display panel and improving its transmittance.

[0128] In some embodiments, such as Figure 3 , Figure 6 As shown, each of the non-peeping pixels 11 includes a first non-peeping sub-pixel 111, a second non-peeping pixel 112, and a non-third non-peeping pixel 113 with different light emission colors, and two of the non-peeping pixels 11 form a non-peeping repeating unit 11a; In the non-peeping repeating unit 11a, the first non-peeping sub-pixel 111 and the second non-peeping sub-pixel 112 are alternately arranged along the second direction Y. One third non-peeping sub-pixel 113 is sandwiched between two first non-peeping sub-pixels 111 along the first direction X, and another third non-peeping sub-pixel 113 is sandwiched between two second non-peeping sub-pixels 112 along the first direction X. This allows the positions of the peeping sub-pixels and non-peeping sub-pixels to be adjusted, reducing the overlap area between the light-blocking part and the light-transmitting hole, thereby increasing the light-transmitting area of ​​the light-transmitting hole and further improving the transmittance of the display panel.

[0129] In some embodiments, the first privacy pixel 121, the second privacy pixel 122, the first non-privacy pixel 111, and the second non-privacy pixel 112 are arranged sequentially along the second direction Y; In the projection in the second direction Y, the third non-peeping sub-pixel 113 is located between adjacent anti-peeping repeating units 12a; the third anti-peeping sub-pixel 123 is located between adjacent non-peeping repeating units 11a; thereby, the positions of the anti-peeping sub-pixels and non-peeping sub-pixels can be adjusted, reducing the overlap area between the light-blocking part and the light-transmitting hole, thereby increasing the light-transmitting area of ​​the light-transmitting hole and further improving the transmittance of the display panel.

[0130] Specifically, such as Figure 3 , Figure 6 As shown, in the first direction X, there are no sub-pixels between the two first light-shielding portions 291a located between two adjacent privacy repeating units 12a, and no sub-pixels are provided between the two second light-shielding portions 294a located between two adjacent privacy repeating units 12a. However, in the privacy repeating unit 12a, there are two third privacy sub-pixels 123 between the two first light-shielding portions 291a and between the two second light-shielding portions 294a. This adjusts the positions of the privacy sub-pixels and non-privacy sub-pixels, reduces the overlap area between the light-shielding portions and the light-transmitting holes, thereby increasing the light-transmitting area of ​​the light-transmitting holes and further improving the transmittance of the display panel.

[0131] Specifically, such as Figure 3 , Figure 6 As shown, in the second direction Y, no sub-pixels in the non-spy pixel 11 are set in the column where the third privacy sub-pixel is located, and no sub-pixels in the privacy pixel 12 are set in the column where the third non-spy sub-pixel is located. This adjusts the positions of the privacy sub-pixels and non-spy sub-pixels, reduces the overlap area between the light-blocking part and the light-transmitting hole, thereby increasing the light-transmitting area of ​​the light-transmitting hole and further improving the transmittance of the display panel.

[0132] In some embodiments, such as Figure 3 , Figure 6As shown, the first light-shielding portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a first notch 411 on the side facing the non-privacy repeating unit 11a, thereby preventing the first light-shielding portion 291a from blocking the non-privacy sub-pixel, reducing the area of ​​the first light-shielding portion, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0133] Specifically, such as Figure 3 , Figure 6 As shown, the oblique light emission of the first non-privacy sub-pixel 111 may be affected by the first light-shielding portions 291a on both sides of the first privacy sub-pixel 121. Therefore, the first light-shielding portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 can be provided with a first notch 411 on the side facing the non-privacy repeating unit 11a to reduce the obstruction of the light emission of the first non-privacy sub-pixel 111 by the first light-shielding portion 291a and improve the display effect of the display panel.

[0134] Specifically, such as Figure 3 , Figure 6 As shown, the width of the first light-blocking portion 291a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the second direction Y is smaller than the width of the first light-blocking portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 in the second direction Y. This results in different blocking effects of the first light-blocking portion 291a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 and the first light-blocking portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 on the light emitted from the first non-privacy sub-pixel 111. In this embodiment, by providing a first notch 411 on the side of the first light-blocking portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 facing the non-privacy repeating unit 11a, the symmetry and uniformity of the light emitted from different directions of the first non-privacy sub-pixel 111 can be improved, thereby improving the display effect.

[0135] In some embodiments, such as Figure 3 , Figure 6 As shown, the second light-shielding portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 has a second notch 412 on the side facing the non-privacy repeating unit 11a, thereby preventing the second light-shielding portion 294a from blocking the non-privacy sub-pixel, reducing the area of ​​the second light-shielding portion 294a, and increasing the light-transmitting area of ​​the display panel; and making the brightness of the non-privacy sub-pixel similar or even the same at different angles, improving the brightness symmetry of different directions.

[0136] Specifically, such as Figure 3 , Figure 6 As shown, the oblique light emission of the first non-privacy sub-pixel 111 may be affected by the second light-shielding portions 294a on both sides of the first privacy sub-pixel 121. Therefore, the second light-shielding portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 can be provided with a first notch 411 on the side facing the non-privacy repeating unit 11a to reduce the obstruction of the light emission of the first non-privacy sub-pixel 111 by the second light-shielding portion 294a and improve the display effect of the display panel.

[0137] Specifically, such as Figure 3 , Figure 6 As shown, the width of the second light-blocking portion 294a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the second direction Y is smaller than the width of the second light-blocking portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 in the second direction Y. This results in different blocking effects of the second light-blocking portion 294a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 and the second light-blocking portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 on the light emitted from the first non-privacy sub-pixel 111. In this embodiment, by providing a second notch 412 on the side of the second light-blocking portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 facing the non-privacy repeating unit 11a, the symmetry and uniformity of the light emitted from different directions of the first non-privacy sub-pixel 111 can be improved, thereby improving the display effect.

[0138] In some embodiments, such as Figure 3 , Figure 6 As shown, the first light-shielding part 291a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 has a third notch 413 on the side facing the third non-privacy sub-pixel 113; thereby, the first light-shielding part 291a can be prevented from blocking the third non-privacy sub-pixel, reducing the area of ​​the first light-shielding part 291a and increasing the light-transmitting area of ​​the display panel; and the brightness of the non-privacy sub-pixel at different angles can be similar or even the same, improving the brightness symmetry of different directions.

[0139] Specifically, such as Figure 3 , Figure 6As shown, the oblique light emission of the third non-privacy sub-pixel 113 may be affected by the first light-shielding part 291a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123, and will also be affected by the two privacy repeating units 12a. Therefore, the first light-shielding part 291a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 may be provided with a third notch 413 on the side facing the third non-privacy sub-pixel 113, thereby reducing the obstruction of the light emission of the third non-privacy sub-pixel 113 by the first light-shielding part 291a and improving the display effect of the display panel.

[0140] In some embodiments, such as Figure 3 , Figure 6 As shown, the second light-shielding part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 has a fourth notch 414 on the side facing the third non-privacy sub-pixel 113; thereby, the second light-shielding part 294a can be prevented from blocking the third non-privacy sub-pixel 113, reducing the area of ​​the second light-shielding part 294a and increasing the light-transmitting area of ​​the display panel; and the brightness of the non-privacy sub-pixel at different angles can be similar or even the same, improving the brightness symmetry of different directions.

[0141] Specifically, such as Figure 3 , Figure 6 As shown, the oblique light emission of the third non-privacy sub-pixel 113 may be affected by the second light-shielding part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123, and will also be affected by the two privacy repeating units 12a. Therefore, the second light-shielding part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 may be provided with a fourth notch 414 on the side facing the third non-privacy sub-pixel 113, thereby reducing the obstruction of the light emission of the third non-privacy sub-pixel 113 by the second light-shielding part 294a and improving the display effect of the display panel.

[0142] In some embodiments, such as Figure 3 , Figure 6 As shown, the first light-shielding portions 291a on both sides of the privacy repeating unit 12a are symmetrically arranged; and the axis of symmetry can be the central axis of the third privacy sub-pixel 123.

[0143] In some embodiments, such as Figure 3 , Figure 6 As shown, the second light-shielding portions 294a on both sides of the privacy repeating unit 12a are symmetrically arranged; and the axis of symmetry can be the central axis of the third privacy sub-pixel 123.

[0144] In some embodiments, such as Figure 3 , Figure 6As shown, the first light-blocking portions 291a on both sides of the third privacy pixel 123 are symmetrically arranged; and the axis of symmetry can be the central axis of the third privacy pixel 123.

[0145] In some embodiments, such as Figure 3 , Figure 6 As shown, the second light-blocking portions 294a on both sides of the third privacy pixel 123 are symmetrically arranged; and the axis of symmetry can be the central axis of the third privacy pixel 123.

[0146] In some embodiments, such as Figure 3 , Figure 6 As shown, in two adjacent privacy repeating units 12a, the first light-blocking portion 291a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in one privacy repeating unit 12a is opposite to and symmetrically arranged with the first light-blocking portion 291a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the other privacy repeating unit 12a; and the axis of symmetry can be the central axis of the third non-privacy sub-pixel 113.

[0147] In some embodiments, such as Figure 3 , Figure 6 As shown, in two adjacent privacy repeating units 12a, the second light-blocking part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in one privacy repeating unit 12a is opposite to and symmetrically arranged with the second light-blocking part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the other privacy repeating unit 12a; and the axis of symmetry can be the central axis of the third non-privacy sub-pixel 113.

[0148] In some embodiments, such as Figure 3 , Figure 6 As shown, two adjacent privacy repeating units 12a can be symmetrically arranged; and the axis of symmetry can be the central axis of the third non-privacy sub-pixel 113.

[0149] In some embodiments, such as Figure 3 , Figure 6 As shown, two adjacent non-spyware repeating units 11a can be symmetrically arranged; and the axis of symmetry can be the central axis of the third spyware sub-pixel 123.

[0150] In some embodiments, such as Figure 3 , Figure 6As shown, the display panel 1 also includes an array of light-transmitting holes 33. In two adjacent rows of light-transmitting holes 33, the projection of one row of light-transmitting holes 33 onto the substrate 21 is located between one row of the first non-privacy pixel 111 and one row of the second non-privacy pixel 112, and the projection of one row of light-transmitting holes 33 onto the substrate 21 is located outside the projection range of the first light-shielding part 291a and the second light-shielding part 294a onto the substrate 21. This ensures that some light-transmitting holes 33 do not overlap with the first light-shielding part 291a and the second light-shielding part 294a, preventing the first light-shielding part 291a and the second light-shielding part 294a from blocking the light-transmitting holes, thereby increasing the effective light-transmitting area of ​​the light-transmitting holes and improving the transmittance of the display panel.

[0151] Specifically, compared to the contrast display device, the projections of each light-transmitting hole on the substrate overlap with the projection of the first light-shielding part on the substrate, such as... Figure 3 , Figure 6 As shown, in this embodiment of the application, by adjusting the position of each sub-pixel, the projection of some light-transmitting holes 33 on the substrate 21 does not overlap with the projection of the first light-shielding part 291a and the second light-shielding part 294a on the substrate 21, thereby increasing the effective light-transmitting area of ​​the light-transmitting holes and improving the transmittance of the display panel.

[0152] In some embodiments, such as Figure 3 , Figure 6 As shown, the projection of the other row of light-transmitting holes 33 on the substrate 21 is between the first row of privacy sub-pixels 121 and the second row of privacy sub-pixels 122, and the projection of the other row of light-transmitting holes 33 on the substrate 21 overlaps with the projection of the first light-shielding layer 291 and the second light-shielding layer 294 on the substrate 21. Wherein, the overlap area of ​​the light-transmitting hole 33 with the first light-blocking portion 291a and the second light-blocking portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 is greater than the overlap area of ​​the light-transmitting hole 33 with the first light-blocking portion 291a and the second light-blocking portion 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123.

[0153] Specifically, such as Figure 3 , Figure 6As shown, when setting the light-transmitting hole, some light-transmitting holes 33 cannot avoid the first light-shielding part 291a and the second light-shielding part 294a, causing the light-transmitting hole 33 to overlap with the first light-shielding part 291a and the second light-shielding part 294a. Since the gap between two adjacent privacy repeating units 12a is relatively large, when setting the light-transmitting hole 33, the overlap area between the light-transmitting hole and the first light-shielding part 291a and the second light-shielding part 294a located on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 can be made smaller than the overlap area between the light-transmitting hole 33 and the first light-shielding part 291a and the second light-shielding part 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123. This increases the effective light-transmitting area of ​​the light-transmitting hole and improves the transmittance of the display panel.

[0154] In some embodiments, such as Figure 3 , Figure 6 As shown, the width H1 of the first privacy sub-pixel 121 in the second direction Y is smaller than the width H3 of the third privacy sub-pixel 123 in the second direction Y, the width of the second privacy sub-pixel 122 in the second direction Y is smaller than the width H3 of the third privacy sub-pixel 123 in the second direction Y, and the width L1 of the first light-blocking portion 291a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 in the second direction Y is greater than the width L2 of the first light-blocking portion 291a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the second direction Y. This makes the light-blocking effect of the first light-blocking portion 291a better for each sub-pixel, and can minimize the occupied area of ​​the first light-blocking portion 291a, improve the transmittance of the display panel, improve the viewing angle performance of the display panel, and slow down the brightness decay of the display panel.

[0155] Specifically, such as Figure 3 , Figure 6 As shown, the width of the third privacy pixel 123 in the second direction Y is greater than the width of the first privacy pixel 121 in the second direction Y, and the width of the third privacy pixel 123 in the second direction Y is greater than the width of the second privacy pixel 122 in the second direction Y. This makes the width of the first light-blocking portion 291a on both sides of the third privacy pixel 123 greater than the width of the first light-blocking portion 291a on the side of the first privacy pixel 121 away from the third privacy pixel 123. This can block the light from each privacy pixel at a large angle, thus improving the privacy effect.

[0156] In some embodiments, such as Figure 3 , Figure 6As shown, the width H1 of the first privacy sub-pixel 121 in the second direction Y is smaller than the width H3 of the third privacy sub-pixel 123 in the second direction Y, the width of the second privacy sub-pixel 122 in the second direction Y is smaller than the width H3 of the third privacy sub-pixel 123 in the second direction Y, and the width L3 of the second light-blocking portion 294a located between the first privacy sub-pixel 121 and the third privacy sub-pixel 123 in the second direction Y is greater than the width L4 of the second light-blocking portion 294a on the side of the first privacy sub-pixel 121 away from the third privacy sub-pixel 123 in the second direction Y. This makes the second light-blocking portion 294a have a better light-blocking effect on each sub-pixel, and can minimize the area occupied by the second light-blocking portion 294a, improve the transmittance of the display panel, improve the viewing angle performance of the display panel, and slow down the brightness decay of the display panel.

[0157] Specifically, such as Figure 3 , Figure 6 As shown, the width of the third privacy pixel 123 in the second direction Y is greater than the width of the first privacy pixel 121 in the second direction Y, and the width of the third privacy pixel 123 in the second direction Y is greater than the width of the second privacy pixel 122 in the second direction Y. This makes the width of the second light-blocking portion 294a on both sides of the third privacy pixel 123 greater than the width of the second light-blocking portion 294a on the side of the first privacy pixel 121 away from the third privacy pixel 123. This can block the light from each privacy pixel at a large angle, thus improving the privacy effect.

[0158] Specifically, the width of the first non-peeping sub-pixel 111 in the first direction X ranges from 10 micrometers to 13 micrometers, the width of the second non-peeping sub-pixel 112 in the first direction X ranges from 10 micrometers to 13 micrometers, and the width of the third non-peeping sub-pixel 113 in the first direction X ranges from 10 micrometers to 13 micrometers; the width of the first privacy sub-pixel 121 in the first direction X ranges from 10 micrometers to 13 micrometers, the width of the second privacy sub-pixel 122 in the first direction X ranges from 10 micrometers to 13 micrometers, and the width of the third privacy sub-pixel 123 in the first direction X ranges from 10 micrometers to 13 micrometers.

When the pixel arrangement of the display panel is other pixel arrangements, a first light-shielding layer 291 and a second light-shielding layer 294 can be set accordingly. For example, if the pixel arrangement of the display panel is SPR, the privacy pixels in the display panel include one first privacy sub-pixel, two second privacy sub-pixels, and one third privacy pixel. The first privacy sub-pixel and the third privacy sub-pixel are alternately arranged in the same column and the first privacy sub-pixel and the third privacy sub-pixel are alternately arranged in the same row.

The brightness is 49.8 on the left, 32 on the top, and 38.6 on the bottom. In contrast, the brightness of the display device in the sharing mode at 30-degree, 45-degree, and 60-degree viewing angles is 37.4%, 10.7%, and 3.6% of the normal viewing brightness, respectively. However, in the sharing mode of the display panel in this embodiment, the brightness is 63.4%, 27.7%, and 10.2% of the normal viewing brightness, respectively. Therefore, the display panel provided in this embodiment increases the transmittance of the display panel, improves the field of view performance, and reduces brightness attenuation.
