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, the display effect of these panels has been found to be poor.

[0003] Therefore, existing OLED display devices suffer from poor display performance. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the technical problem of poor display effect 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 a plurality of privacy-protecting sub-pixels and a plurality of non-privacy-protecting sub-pixels, the display panel comprising: Substrate; A light-emitting material layer is disposed on one side of the substrate, and the light-emitting material layer includes a privacy light-emitting part corresponding to the privacy sub-pixel; A first light-shielding layer is disposed on the side of the light-emitting material layer away from the substrate, and the first light-shielding layer includes a plurality of first light-shielding portions; A second light-shielding layer is disposed on the side of the first light-shielding layer away from the light-emitting material layer, and the second light-shielding layer includes a plurality of second light-shielding portions; In the projection on the substrate, in the first direction, the first light-shielding part and the second light-shielding part are provided on both sides of the privacy light-emitting part; in the second direction, at least one side of the privacy light-emitting part is not provided with the first light-shielding part and the second light-shielding part; 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, through projection on a substrate, ensures that at least one side of at least one privacy light-emitting part is not provided with a first light-shielding part and a second light-shielding part in a second direction. This allows the user to use the display panel without the first and second light-shielding parts blocking the side or sides where privacy is not required, reducing the brightness attenuation of the privacy light-emitting part and improving the display effect. In the first direction, the privacy light-emitting part is provided with a first light-shielding part and a second light-shielding part on both sides, still achieving the privacy effect on the sides where privacy is required, thereby balancing the privacy effect and display effect of the display panel.

[0022] 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.

[0023] To illustrate the principle behind the technical problem in this application, a contrast display device is provided. It should be understood that this contrast display device is 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 mode, both the privacy unit 142 and the non-privacy unit 141 are lit. In privacy mode, only the privacy unit 142 is lit to achieve privacy display.

[0024] like 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, and 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. In terms of film structure, a first black matrix film 151 is set around both the privacy sub-pixel and the non-privacy sub-pixel, and a second black matrix film 152 is also set around the privacy sub-pixel. The first black matrix film 151 and the second black matrix film 152 are extended outward relative to the pixel definition film 153. Thus, the light emission angle of the non-privacy unit 141 is controlled by the first black matrix film 151, and the large viewing angle and wide viewing angle of the privacy unit 142 are blocked by the first black matrix film 151 and the second black matrix film 152, so as to achieve 360-degree omnidirectional privacy.

[0025] However, in actual use, such as Figure 2 As shown, it was found that the top (161), bottom (162), left (163), and right (164) positions of the contrast display device 16 all entered privacy mode, resulting in a decrease in brightness over a wide viewing angle. When a user uses the contrast display device 16, the angle created by holding or tilting it, along with the varying angles between the user's eye and the device, negatively impacts the user experience. For example, when a user holds the device, the brightness reduction caused by privacy mode at both the top and bottom negatively affects the user's experience, diminishes the subjective aesthetic appeal of the display, and leads to poor display quality. Therefore, existing OLED display devices suffer from a technical problem of poor display performance.

[0026] This application provides a display panel and a display device to address the aforementioned technical problems.

[0027] 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.

[0028] 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.

[0029] 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 to bond the driving chip.

[0030] Specifically, such as Figure 3 , Figures 6 to 8 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Specifically, the arrangement of sub-pixels in non-spy pixel 11 and spy pixel 12 is not limited in this application embodiment. The following embodiments use realRGB, SPR or other arrangement of sub-pixels as examples for illustration.

[0036] 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.

[0037] Specifically, such as Figure 4 , Figure 9 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.

[0038] Specifically, such as Figure 4 , Figure 9 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.

[0039] 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.

[0040] Specifically, the dimming function layer may include a first refractive index layer and a second refractive index layer. The refractive index of the second refractive index layer is greater than that of the first refractive index layer. The first refractive index layer is disposed between the touch layer and the second refractive index layer. The first refractive index layer has an opening in the area of ​​the corresponding sub-pixel. The second refractive index layer is disposed on the first refractive index layer and fills the opening.

[0041] Specifically, the refractive index of the first refractive index layer ranges from 1.45 to 1.55, and the refractive index of the second refractive index layer ranges from 1.6 to 1.8.

[0042] Specifically, such as Figure 4 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.

[0043] Specifically, the first planarization layer 28 can serve as the first refractive index layer.

[0044] 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.

[0045] Specifically, such as Figure 9As 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 9 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 9 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 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 9 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] Specifically, when a first light-blocking layer 291 and a second light-blocking layer 294 are provided on the second direction Y of the privacy pixel 12, the brightness of the privacy pixel 12 is 1% to 10% of the brightness of the normal viewing angle (which can be regarded as a 0-degree viewing angle) on the second direction Y at a viewing angle of 30 degrees to 45 degrees.

[0059] Specifically, to illustrate the relative positions of the first light-blocking layer 291, the second light-blocking layer 294, and each sub-pixel, the following is provided: Figure 5 , Figure 5 (a) in the middle is Figure 3 An exploded view of the relative positions of the first light-blocking layer 291 and each sub-pixel on the plane. Figure 5 (b) in the middle is Figure 3 The decomposition diagram of the second light-blocking layer 294 and the relative positions of each sub-pixel on the plane. Similarly, it can be determined that... Figure 6 , Figure 7 , Figure 8 The structure and relative positions of the first light-shielding layer 291, the second light-shielding layer 294, and each sub-pixel on the plane are not described in detail here.

[0060] like Figures 3 to 9 As shown, this application embodiment provides a display panel 1, which includes a plurality of privacy-protected sub-pixels 15 and a plurality of non-privacy-protected sub-pixels 14. The display panel 1 includes a substrate 21, a light-emitting material layer 253, a first light-shielding layer 291, and a second light-shielding layer 294. The light-emitting material layer 253 is disposed on one side of the substrate 21, and the light-emitting material layer 253 includes a privacy-protected light-emitting portion 253b corresponding to the privacy-protected sub-pixels 15. The first light-shielding layer 291 is disposed on the side of the light-emitting material layer 253 away from the substrate 21, and the first light-shielding layer 291 includes a plurality of first light-shielding portions 291a. The second light-shielding layer 294 is disposed on the side of the first light-shielding layer 291 away from the light-emitting material layer 253, and the second light-shielding layer 294 includes a plurality of second light-shielding portions 294a. In the projection onto the same plane, in the first direction X, the first light-shielding part 291a and the second light-shielding part 294a are provided on both sides of the privacy light-emitting part 253b; in the second direction Y, at least one side of at least one of the privacy light-emitting part 253b is not provided with the first light-shielding part 291a and the second light-shielding part 294a; 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 1 in which, in the projection on the same plane, at least one side of at least one privacy light-emitting part 253b is not provided with a first light-shielding part 291a and a second light-shielding part 294a in the second direction Y. This ensures that when the user uses the display panel, the side or sides that do not require privacy are not blocked by the first and second light-shielding parts, reducing the brightness attenuation of the privacy light-emitting part and improving the display effect. In the first direction X, both sides of the privacy light-emitting part 253b are provided with a first light-shielding part 291a and a second light-shielding part 294a, so that the privacy effect on the sides that require privacy can still be achieved, thereby taking into account both the privacy effect and the display effect of the display panel.

[0062] Specifically, since the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting material layer 253 are different film layers and are located on different planes in the thickness direction of the display panel, when explaining the positional relationship of the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting material layer 253 in the first direction X and the second direction Y, it is necessary to make the first light-shielding layer 291, the second light-shielding layer 294, and the light-emitting material layer 253 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 material layer 253 on the same plane.

[0063] It is understood that this plane can be a substrate, a ground plane, or other films or interfaces thereof. The following embodiments use a projection on a substrate as an example for illustration.

[0064] Specifically, regarding the projection onto the same plane, in the first direction X, the first light-blocking part 291a and the second light-blocking part 294a are provided on both sides of the projection of the privacy light-emitting part 253b onto a plane. That is, in the first direction X, the first light-blocking part 291a and the second light-blocking part 294a are provided on both sides of the projection of the privacy light-emitting part 253b onto a plane. Similarly, the meaning of other relative positions can be determined, which will not be elaborated here.

[0065] 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.

[0066] Specifically, in the comparison display device, the privacy pixel is provided with a first light-blocking part 291a and a second light-blocking part 294a on all four sides. This makes the brightness attenuation of the wide viewing angle of the comparison display device faster in privacy mode. However, users often hold the display panel, mainly at the bottom of the display panel, and the display panel is tilted to a certain extent. Therefore, the bottom of the display panel usually does not need to be protected against privacy.

[0067] Meanwhile, in actual use, privacy protection for 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. Therefore, based on this discovery, this application embodiment provides a first light-shielding part 291a and a second light-shielding part 294a on at most one side of at least one privacy-protecting light-emitting part 253b in the second direction Y. This eliminates the need for privacy protection on one or both sides of the display panel, improves the display effect, and does not affect the privacy protection function.

[0068] In some embodiments, the light-emitting material layer 253 further includes a non-peeping light-emitting portion 253a corresponding to the non-peeping sub-pixel 14.

[0069] In some embodiments, in the first direction X, a first light-shielding part 291a is provided between two adjacent non-privacy light-emitting parts 253a, and no second light-shielding part 294a is provided between two adjacent non-privacy light-emitting parts 253a; thereby, the second light-shielding part 294a can be prevented from blocking the light of the non-privacy light-emitting parts 253a, and the brightness symmetry of the non-privacy pixels can be balanced by the first light-shielding part 291a.

[0070] In some embodiments, such as Figure 8 As shown, in the projection on the substrate 21, in the second direction Y, at least one side of the privacy light-emitting part 253b is provided with the first light-shielding part 291a and the second light-shielding part 294a, which extend along the first direction X; thereby enabling light with a wide viewing angle to be emitted from the lower side of the display panel 1, and the lower side of the display panel 1 does not need to be privacy-protected, thus improving the display effect.

[0071] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, in the projection on the substrate 21, in the second direction Y, neither the first light-shielding part 291a nor the second light-shielding part 294a is provided on either side of the privacy-protecting light-emitting part 253b. The first light-shielding part 291a and the second light-shielding part 294a extend along the second direction Y. This allows the display panel to emit light with a wide viewing angle in the vertical direction, and the display effect in the vertical direction of the display panel is not affected. Meanwhile, privacy protection can still be achieved in the horizontal direction, which is mainly required to protect against privacy, thus improving the display effect.

[0072] Specifically, such as Figure 3 , Figures 6 to 8As shown, the display panel 1 includes a binding area 102a. In the projection on the same plane, in the second direction Y, at least one of the privacy light-emitting parts 253b is provided with the first light-shielding part 291a and the second light-shielding part 294a on the side away from the binding area 102a.

[0073] Specifically, such as Figure 8 As shown, in the second direction Y, the upper side of the first privacy pixel 121, the second privacy pixel 122 and the third privacy pixel 123 are provided with a first light-blocking part 291a and a second light-blocking part 294a.

[0074] Specifically, such as Figure 8 As shown, in the second direction Y, there is no first light-blocking portion 291a and second light-blocking portion 294a between the first privacy sub-pixel 121 and the second non-privacy sub-pixel 112, but there is a first light-blocking portion 291a and second light-blocking portion 294a between the second privacy sub-pixel 122 and the first non-privacy sub-pixel 111. Furthermore, it can be seen that when the privacy pixel 12 is closer to the bonding area than the adjacent non-privacy pixel 11, there is a first light-blocking portion 291a and second light-blocking portion 294a between the third non-privacy sub-pixel 113 and the third privacy pixel 123. When the non-peeping pixel 11 is closer to the bonding area than the adjacent peeping pixel 12, the first light-shielding part 291a and the second light-shielding part 294a are not provided between the third non-peeping sub-pixel 113 and the third peeping sub-pixel 123, while the first light-shielding sub-pixel 121 and the second peeping sub-pixel 122 are provided with the first light-shielding part 291a and the second light-shielding part 294a. This allows light with a wide viewing angle to be emitted from the lower side of the display panel 1, and the lower side of the display panel 1 does not need to be peeping, thus improving the display effect.

[0075] Specifically, such as Figure 8 As shown, the distance between the first light-blocking portion 291a and the second privacy pixel 122 between the first privacy pixel 121 and the second privacy pixel 122 is greater than the distance between the first light-blocking portion 291a and the first privacy pixel 121 between the first privacy pixel 121 and the second privacy pixel 122.

[0076] Specifically, such as Figure 8 As shown, the distance between the second light-blocking portion 294a and the second privacy pixel 122 between the first privacy pixel 121 and the second privacy pixel 122 is greater than the distance between the second light-blocking portion 294a and the first privacy pixel 121 between the first privacy pixel 121 and the second privacy pixel 122.

[0077] Specifically, in Figure 3 , Figures 6 to 8In this context, the structure of each sub-pixel can be viewed as the structure of the light-emitting part of each sub-pixel, and the structure of each sub-pixel can be viewed as the structure of the opening of the pixel definition layer.

[0078] Specifically, the positions of the first light-shielding part 291a and the second light-shielding part 294a can be adjusted to allow light from the upper side of the display panel 1 to be emitted from a wide angle, and the upper side of the display panel is not protected from privacy, thereby improving the display effect.

[0079] Specifically, Figure 8 The following explanation uses the arrangement of sub-pixels in privacy pixel 12 and non-privacy pixel 11 as an example of realRGB arrangement. When the arrangement of sub-pixels in privacy pixel 12 and non-privacy pixel 11 is SPR arrangement, it is also possible to achieve that the top or bottom of the display panel is not privacy-protected, thus improving the display effect. This will not be elaborated further here.

[0080] Specifically, such as Figure 3 , Figure 6 , Figure 7 As shown, the display panel 1 includes a bonding area 102a, which is disposed on one side of the display panel 1 along the second direction Y. In the projection on the substrate 21, the first light-shielding part 291a and the second light-shielding part 294a extend along the second direction Y. This allows the display panel to emit light with a wide viewing angle in the vertical direction, and the display effect in the vertical direction of the display panel is not affected, while the privacy protection in the horizontal direction, which is mainly required, can still be achieved, thus improving the display effect.

[0081] Specifically, such as Figure 3 , Figure 6 , Figure 7 As shown, the display panel 1 includes a binding area 102a, which is disposed on one side of the display panel 1 along the second direction Y. In the projection on the same plane, in the second direction Y, neither the first light-shielding part 291a nor the second light-shielding part 294a is disposed on either side of the privacy-proof light-emitting part 253b; thereby, the display panel can emit light with a wide viewing angle in the vertical direction, and the display effect in the vertical direction of the display panel is not affected, while privacy can still be achieved in the horizontal direction where privacy is mainly required, thus improving the display effect.

[0082] Specifically, such as Figure 3 , Figure 6 , Figure 7 As shown, in the second direction Y, there is no first light-blocking part 291a and second light-blocking part 294a between each sub-pixel, so that the display panel can emit light normally in the vertical direction, thereby improving the display effect.

[0083] In some embodiments, such as Figure 3 , Figure 8 As shown, the multiple privacy pixels 15 include a first privacy pixel 121, a second privacy pixel 122, and a third privacy pixel 123 with different light-emitting colors. One first privacy pixel 121, one second privacy pixel 122, and one third privacy pixel 123 constitute one privacy pixel 12. Thus, when the display panel adopts a real RGB layout, by adjusting the positions of the first light-blocking part 291a and the second light-blocking part 294a, the brightness in at least one direction can be increased, thereby improving the display effect of the display panel.

[0084] In some embodiments, such as Figure 3 , Figure 8 As shown, the plurality of non-privacy sub-pixels 14 include a first non-privacy sub-pixel 111, a second non-privacy sub-pixel 112, and a third non-privacy sub-pixel 113 with different light-emitting colors. One first non-privacy sub-pixel 111, one second non-privacy sub-pixel 112, and one third non-privacy sub-pixel 113 constitute a non-privacy pixel. Thus, when the display panel adopts a real RGB layout, by adjusting the positions of the first light-blocking part 291a and the second light-blocking part 294a, the brightness in at least one direction can be improved, thereby improving the display effect of the display panel.

[0085] In some embodiments, such as Figure 6 , Figure 7 As shown, the multiple privacy pixels 15 include a first privacy pixel 121, a second privacy pixel 122, and a third privacy pixel 123 with different light-emitting colors. One first privacy pixel 121, two second privacy pixels 122, and one third privacy pixel 123 constitute a privacy pixel 12. Thus, when the display panel adopts an SPR arrangement, by adjusting the positions of the first light-blocking part 291a and the second light-blocking part 294a, the brightness in at least one direction can be increased, thereby improving the display effect of the display panel.

[0086] In some embodiments, such as Figure 6 , Figure 7 As shown, the plurality of non-privacy sub-pixels 14 include a first non-privacy sub-pixel 111, a second non-privacy sub-pixel 112, and a third non-privacy sub-pixel 113 with different light-emitting colors. One first non-privacy sub-pixel 111, two second non-privacy sub-pixels 112, and one third non-privacy sub-pixel 113 constitute a non-privacy pixel. Thus, when the display panel adopts an SPR arrangement, by adjusting the positions of the first light-blocking part 291a and the second light-blocking part 294a, the brightness in at least one direction can be improved, thereby improving the display effect of the display panel.

[0087] In some embodiments, such as Figure 3 , Figure 7, Figure 8 As shown, the privacy pixel 12 and the non-privacy pixel 11 are alternately arranged along the first direction X, and the privacy pixel 12 and the non-privacy pixel 11 are alternately arranged along the second direction Y, thereby improving the display effect.

[0088] In some embodiments, such as Figure 6 As shown, a plurality of privacy pixels 12 are arranged in the same column along the second direction Y, and a plurality of non-privacy pixels 11 are arranged in the same column along the second direction Y. The privacy pixels 12 and the non-privacy pixels 11 are alternately arranged along the first direction X, thereby reducing the difficulty of the manufacturing process.

[0089] In some embodiments, such as Figure 3 As shown, in the second direction Y, the second non-peeping sub-pixel 112, the first non-peeping sub-pixel 111, the second peeping sub-pixel 122, and the first peeping sub-pixel 121 are sequentially arranged along the second direction Y. The third non-peeping sub-pixel 113 and the third peeping sub-pixel 123 are alternately arranged along the second direction Y to form a first sub-pixel column 131. In two adjacent first sub-pixel columns 131, the projections of the third non-peeping sub-pixel 113 and the third peeping sub-pixel 123 in the first direction X are misaligned. Thus, the display effect can be improved by the misalignment of the peeping sub-pixel 12 and the non-peeping sub-pixel 111. Furthermore, the misalignment of the peeping sub-pixel 123 and the non-peeping sub-pixel 113 in two adjacent first sub-pixel columns 131 can leave space for structures such as support columns.

[0090] Specifically, such as Figure 3 , Figure 8 As shown, privacy pixel 12 and non-privacy pixel 11 are alternately arranged along the first direction X, and privacy pixel 12 and non-privacy pixel 11 are alternately arranged along the second direction Y. The second non-privacy sub-pixel 112, the first non-privacy sub-pixel 111, the second privacy pixel 122, and the first privacy sub-pixel 121 are arranged sequentially along the second direction Y. The third non-privacy sub-pixel 113 and the third privacy pixel 123 are alternately arranged along the second direction Y. In two adjacent first sub-pixel columns 131, the projections of the third non-privacy pixel 113 and the third privacy pixel 123 on the first direction X are misaligned.

[0091] Specifically, multiple privacy pixels 12 can be arranged in the same column along the second direction Y, and multiple non-privacy pixels 11 can be arranged in the same column along the second direction Y. The privacy pixels 12 and the non-privacy pixels 11 can be arranged alternately along the first direction X. The second non-privacy sub-pixel 112, the first non-privacy sub-pixel 111, the second privacy pixel 122, and the first privacy sub-pixel 121 can be arranged sequentially along the second direction Y. The third non-privacy sub-pixel 113 and the third privacy pixel 123 can be arranged alternately along the second direction Y.

[0092] In some embodiments, such as Figure 6 , Figure 7 As shown, in the second direction Y, the third non-peeping pixel 113, the first non-peeping pixel 111, the third peeping pixel 123, and the first peeping pixel 121 are sequentially arranged along the second direction Y. The first non-peeping pixel 111 and the third peeping pixel 123 are alternately arranged along the first direction X, and the third non-peeping pixel 113 and the first peeping pixel 121 are alternately arranged along the first direction X. Every two second non-peeping pixels 112 and every two second peeping pixels 122 are arranged along the second direction Y. The second direction Y is alternately set; the projections of the first non-peeping sub-pixel 111, the second non-peeping sub-pixel 112, and the third non-peeping sub-pixel 113 in the first direction X do not overlap; the projections of the first privacy sub-pixel 121, the second privacy sub-pixel 122, and the third privacy sub-pixel 123 in the first direction do not overlap; by setting the sub-pixels in a staggered manner, the width occupied by the privacy sub-pixel 12 can be narrowed, the distance between the privacy sub-pixel 12 and the non-peeping sub-pixel 11 can be increased, the occupancy of the non-peeping sub-pixel 11 can be reduced, and the display effect can be improved.

[0093] Specifically, such as Figure 6As shown, multiple privacy pixels 12 are arranged in the same column along the second direction Y, and multiple non-privacy pixels 11 are arranged in the same column along the second direction Y. A third non-privacy sub-pixel 113, a first non-privacy sub-pixel 111, a third privacy sub-pixel 123, and a first privacy sub-pixel 121 are arranged sequentially along the second direction Y. The first non-privacy sub-pixel 111 and the third privacy sub-pixel 123 are alternately arranged along the first direction X. The third non-privacy sub-pixel 113 and the first privacy sub-pixel 121 are alternately arranged along the first direction X. Every two second non-privacy pixels 112 and every two second privacy pixels 122 are alternately arranged along the second direction Y. The projections of the first non-privacy pixel 111, the second non-privacy pixel 112, and the third non-privacy pixel 113 on the first direction X do not overlap. The projections of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 on the first direction do not overlap.

[0094] Specifically, such as Figure 7 As shown, privacy pixels 12 and non-privacy pixels 11 are alternately arranged along the first direction X, and privacy pixels 12 and non-privacy pixels 11 are alternately arranged along the second direction Y. The third non-privacy sub-pixel 113, the first non-privacy sub-pixel 111, the third privacy sub-pixel 123, and the first privacy sub-pixel 121 are arranged sequentially along the second direction Y. The first non-privacy sub-pixel 111 and the third privacy sub-pixel 123 are alternately arranged along the first direction X, and the third non-privacy sub-pixel 113 and the first privacy sub-pixel 121 are alternately arranged along the first direction X. Every two second non-privacy sub-pixels 112 and every two second privacy sub-pixels 122 are alternately arranged along the second direction Y. The projections of the first non-privacy pixel 111, the second non-privacy pixel 112, and the third non-privacy pixel 113 on the first direction X do not overlap. The projections of the first privacy pixel 121, the second privacy pixel 122, and the third privacy pixel 123 on the first direction do not overlap.

[0095] In some embodiments, such as Figures 3 to 4 , Figures 6 to 8 The display panel further includes a pixel definition layer 252, which is disposed between the light-emitting material layer 253 and the substrate 21. In the first direction X, the width A2 of the portion of the pixel definition layer 252 located between adjacent privacy sub-pixels 15 is equal to the width A1 of the portion of the pixel definition layer 252 located between the non-privacy sub-pixels 14, thereby improving the uniformity of display at the viewing angle.

[0096] Specifically, in the first direction X, the width of the portion of the pixel definition layer 252 located between adjacent privacy sub-pixels 15 is not equal to the width of the portion of the pixel definition layer 252 located between the non-privacy sub-pixels 14.

[0097] In some embodiments, such as Figures 3 to 4 , Figures 6 to 8 In the first direction X, the width B of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 is greater than or equal to the width A2 of the portion of the pixel definition layer 252 located between adjacent privacy sub-pixels 15; thereby reducing the obstruction of the second light-shielding portion 294a above the privacy pixel 12 on the non-privacy pixel 11, increasing the brightness of the non-privacy pixel 11, and improving the display effect.

[0098] Specifically, the width B of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 can be greater than or equal to the width A1 of the portion of the pixel definition layer 252 located between adjacent non-privacy sub-pixels 14.

[0099] In some embodiments, such as Figure 3 , Figure 8 As shown, in the first direction X, the width of the portion of the pixel definition layer 252 located between adjacent privacy sub-pixels 15 ranges from 16 micrometers to 19 micrometers, that is, the value of A2 ranges from 16 micrometers to 19 micrometers, thereby providing sufficient space to set the first light-blocking part 291a and the second light-blocking part 294a, and the first light-blocking part 291a and the second light-blocking part 294a can effectively block light and improve the privacy effect.

[0100] Specifically, such as Figure 3 , Figure 8 As shown, in the first direction X, the width of the portion of the pixel definition layer 252 located between adjacent non-peeping sub-pixels 14 ranges from 16 micrometers to 19 micrometers, that is, the value range of A1 is from 16 micrometers to 19 micrometers.

[0101] Specifically, the width of the portion of the pixel definition layer 252 located between adjacent non-peeping sub-pixels 14 can be 16 micrometers, 17 micrometers, 18 micrometers, or 19 micrometers, and the width of the portion of the pixel definition layer 252 located between adjacent peeping sub-pixels 15 can be 16 micrometers, 17 micrometers, 18 micrometers, or 19 micrometers.

[0102] In some embodiments, such as Figure 3 , Figure 8As shown, in the first direction X, the width of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 ranges from 17 micrometers to 22 micrometers; that is, the value of B ranges from 17 micrometers to 22 micrometers, thereby reducing the obstruction of the second light-shielding portion 294a above the privacy pixel 12 on the non-privacy pixel 11, increasing the brightness of the non-privacy pixel 11, and improving the display effect.

[0103] Specifically, the width of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 can be 17 micrometers, 18 micrometers, 19 micrometers, 20 micrometers, 21 micrometers, or 22 micrometers.

[0104] In some embodiments, such as Figure 6 , Figure 7 As shown, in the first direction X, the width of the portion of the pixel definition layer 252 located between adjacent privacy sub-pixels 15 ranges from 12 micrometers to 14 micrometers, that is, the value of A2 ranges from 12 micrometers to 14 micrometers, thereby providing sufficient space to set the first light-blocking part 291a and the second light-blocking part 294a, and the first light-blocking part 291a and the second light-blocking part 294a can effectively block light and improve the privacy effect.

[0105] Specifically, such as Figure 6 , Figure 7 As shown, in the first direction X, the width of the portion of the pixel definition layer 252 located between adjacent non-peeping sub-pixels 14 ranges from 12 micrometers to 14 micrometers, that is, the value range of A1 is from 12 micrometers to 14 micrometers.

[0106] Specifically, the width of the portion of the pixel definition layer 252 located between adjacent non-peeping sub-pixels 14 can be 12 micrometers, 13 micrometers, or 14 micrometers, and the width of the portion of the pixel definition layer 252 located between adjacent peeping sub-pixels 15 can be 12 micrometers, 13 micrometers, or 14 micrometers.

[0107] In some embodiments, such as Figure 6 , Figure 7 As shown, the width of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 ranges from 22 to 27 micrometers; that is, the value of B ranges from 22 to 27 micrometers, thereby reducing the obstruction of the second light-shielding part 294a above the privacy pixel 12 on the non-privacy pixel 11, increasing the brightness of the non-privacy pixel 11, and improving the display effect.

[0108] Specifically, the width of the portion of the pixel definition layer 252 located between the privacy pixel 12 and the non-privacy pixel 11 can be 22 micrometers, 23 micrometers, 24 micrometers, 25 micrometers, 26 micrometers, or 27 micrometers.

[0109] Specifically, such as Figure 3 , Figures 6 to 8 As shown, from Figure 3 and Figure 8 As can be seen, in the privacy pixel 12 and the non-privacy pixel 11, the projections of sub-pixels located in different columns overlap in the first direction. For example, the projections of the first privacy sub-pixel 121 and the third privacy sub-pixel 123 overlap in the first direction X, and the projections of the first non-privacy sub-pixel 111 and the third non-privacy sub-pixel 113 overlap in the first direction X, resulting in a relatively large spacing between adjacent privacy sub-pixels and a relatively large spacing between adjacent non-privacy sub-pixels.

[0110] And from Figure 6 , Figure 7 As can be seen, in a column of privacy pixels 12, the projections of the privacy sub-pixels located in the two columns are staggered in the first direction X. Similarly, in a column of non-privacy pixels 11, the projections of the non-privacy sub-pixels located in the two columns are staggered in the first direction X. This allows for narrowing the spacing between adjacent privacy sub-pixels 15 when setting the distance between them, and also narrowing the distance between adjacent non-privacy sub-pixels 14 when setting the distance between them. Consequently, the distance between privacy pixels 12 and non-privacy pixels 11 can be increased, reducing the obstruction of the second light-shielding portion 294a above the privacy pixels 12 on the non-privacy pixels 11, increasing the brightness of the non-privacy pixels 11, and improving the display effect.

[0111] In some embodiments, such as Figure 3 , Figure 4 , Figures 6 to 8 As shown, the light-emitting material layer 253 also includes a non-privacy light-emitting part 253a corresponding to the non-privacy sub-pixel. In the first direction X, the distance C between the first light-shielding part 291a and the privacy light-emitting part 253b is smaller than the distance E between the first light-shielding part 291a and the non-privacy light-emitting part 253a. This allows the first light-shielding part 291a to block the large-angle light emission of the privacy sub-pixel 15, reducing the large-angle light emission of the non-privacy sub-pixel 14 and improving the display effect.

[0112] Specifically, when setting the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part 253b, the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part 253b is made as small as possible to improve the privacy protection effect. When setting the distance between the first light-shielding part 291a and the non-privacy-protecting light-emitting part 253a, the distance between the first light-shielding part 291a and the non-privacy-protecting light-emitting part 253a is made relatively large to avoid excessive brightness attenuation in the sharing mode and improve the display effect.

[0113] In some embodiments, such as Figure 3 , Figure 8 As shown, in the first direction X, the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a located between the privacy pixel 12 and the non-peeping pixel 11 ranges from 7 micrometers to 15.5 micrometers; that is, the value of F ranges from 7 micrometers to 15.5 micrometers, so that the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a is relatively large, avoiding excessive brightness attenuation in the sharing mode and improving the display effect.

[0114] Specifically, the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a can be 7 micrometers, 8 micrometers, 9 micrometers, 10 micrometers, 11 micrometers, 12 micrometers, 13 micrometers, 14 micrometers and 15.5 micrometers.

[0115] In some embodiments, in the first direction X, the distance between the first light-shielding part 291a and the non-privacy light-emitting part 253a is in the range of 4 micrometers to 6 micrometers, that is, the value of E is in the range of 4 micrometers to 6 micrometers; making the distance between the first light-shielding part 291a and the non-privacy light-emitting part 253a relatively large, avoiding excessive brightness attenuation in the sharing mode, and improving the display effect.

[0116] Specifically, the distance between the first light-shielding part 291a and the non-peeping light-emitting part 253a can be 4 micrometers, 5 micrometers, and 6 micrometers.

[0117] In some embodiments, such as Figure 6 , Figure 7 As shown, in the first direction X, the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a located between the privacy pixel 12 and the non-peeping pixel 11 ranges from 12 micrometers to 20.5 micrometers; that is, the value of F ranges from 12 micrometers to 20.5 micrometers, so that the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a is relatively large, avoiding excessive brightness attenuation in the sharing mode and improving the display effect.

[0118] Specifically, the distance between the second light-shielding part 294a and the non-peeping light-emitting part 253a can be 12 micrometers, 13 micrometers, 14 micrometers, 15 micrometers, 16 micrometers, 17 micrometers, 18 micrometers, 19 micrometers, 20 micrometers and 20.5 micrometers.

[0119] Specifically, compared to Figure 3 , Figure 8 The projections of sub-pixels located in different columns in the first direction will overlap, such as... Figure 6 , Figure 7As shown, since the projections of the two columns of privacy sub-pixels in a column of privacy pixels 12 are staggered in the first direction X, and the projections of the two columns of non-privacy sub-pixels in a column of non-privacy pixels 11 are also staggered in the first direction X, the spacing between adjacent privacy sub-pixels 15 and adjacent non-privacy sub-pixels 14 can be narrowed. Correspondingly, increasing the spacing between the privacy pixels 12 and non-privacy pixels 11 can simultaneously increase the spacing between the first light-blocking portion and the non-privacy light-emitting portion in the first direction; and / or, increasing the spacing between the second light-blocking portion and the non-privacy light-emitting portion located between the privacy pixels and non-privacy pixels reduces the obstruction of the non-privacy pixels 11 by the second light-blocking portion 294a above the privacy pixels 12, increasing the brightness of the non-privacy pixels 11 and improving the display effect.

[0120] In some embodiments, such as Figure 3 , Figure 8 As shown, when the privacy pixel 12 and the non-privacy pixel 11 are alternately arranged along the first direction X, and the privacy pixel 12 and the non-privacy pixel 11 are alternately arranged along the second direction Y, the distance H between one end of the second light-blocking part 294a located between adjacent privacy sub-pixels 15 and the privacy sub-pixel 15 is 8 micrometers to 12 micrometers; thereby, the light emitted by the privacy sub-pixel 15 can be blocked, while the second light-blocking part 294a is prevented from blocking the light emitted by the non-privacy sub-pixel 14, thus balancing the privacy effect and the display effect.

[0121] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, the width L1 of the privacy pixel 15 in the first direction X is less than or equal to the width L2 of the privacy pixel 15 in the second direction Y; thereby improving the privacy effect.

[0122] Specifically, when the opening area of ​​the privacy sub-pixel 15 is fixed to ensure sufficient brightness lifespan and color lifespan, the smaller the sub-pixel opening size, the better the privacy effect under the same amount of light-shielding expansion. Therefore, when a display panel needs privacy in the first direction, compressing the pixel width in the first direction as much as possible can improve the privacy effect. Since the opening area of ​​the pixel is fixed, the width of the privacy sub-pixel 15 in the first direction X can be less than or equal to the width of the privacy sub-pixel 15 in the second direction Y.

[0123] Specifically, the width of the first privacy pixel 121 in the first direction X is less than or equal to the width of the first privacy pixel 121 in the second direction Y.

[0124] Specifically, the width of the second privacy pixel 122 in the first direction X is less than or equal to the width of the second privacy pixel 122 in the second direction Y.

[0125] Specifically, the width of the third privacy pixel 123 in the first direction X is less than or equal to the width of the third privacy pixel 123 in the second direction Y.

[0126] Specifically, the width of the privacy pixel 15 in the first direction X can be greater than the width of the privacy pixel 15 in the second direction Y.

[0127] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, the width L3 of the non-peeping sub-pixel 14 in the first direction X is less than or equal to the width L4 of the non-peeping sub-pixel 14 in the second direction Y; thereby maintaining pixel consistency and improving display uniformity.

[0128] Specifically, the width of the first non-peeping pixel 111 in the first direction X is less than or equal to the width of the first non-peeping pixel 111 in the second direction Y.

[0129] Specifically, the width of the second non-peeping pixel 112 in the first direction X is less than or equal to the width of the second non-peeping pixel 112 in the second direction Y.

[0130] Specifically, the width of the third non-peeping pixel 113 in the first direction X is less than or equal to the width of the third non-peeping pixel 113 in the second direction Y.

[0131] Specifically, the width of the non-peeping pixel 14 in the first direction X can be made greater than the width of the non-peeping pixel 14 in the second direction Y.

[0132] In some embodiments, in the first direction X, the distance between the first light-shielding part 291a and the privacy light-emitting part 253b is less than or equal to the distance between the second light-shielding part 294a and the privacy light-emitting part 253b.

[0133] Specifically, such as Figure 12 As shown, the distance between the first light-blocking portion 291a and the privacy sub-pixel 15 can be equal to the distance between the second light-blocking portion 294a and the privacy sub-pixel 15, or, as... Figure 3 , Figure 7 , Figure 8 As shown, the distance between the first light-shielding part 291a and the privacy pixel can be smaller than the distance between the second light-shielding part 294a and the privacy pixel.

[0134] In some embodiments, such as Figure 3, Figures 6 to 8 As shown, in the first direction X, the distance between the first light-shielding part 291a and the privacy-preventing light-emitting part 253b ranges from 0.5 micrometers to 1.5 micrometers; the distance between the first light-shielding part 291a and the privacy-preventing light-emitting part 253b is kept as small as possible to improve the privacy effect.

[0135] Specifically, in the first direction X, the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part can be 0.5 micrometers, 0.6 micrometers, 0.7 micrometers, 0.8 micrometers, 0.9 micrometers, 1.0 micrometers, 1.1 micrometers, 1.2 micrometers, 1.3 micrometers, 1.4 micrometers and 1.5 micrometers.

[0136] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, in the first direction X, the distance between the second light-shielding part 294a and the privacy-preventing light-emitting part 253b ranges from 0.5 micrometers to 2 micrometers; the distance between the second light-shielding part 294a and the privacy-preventing light-emitting part 253b is kept as small as possible to improve the privacy effect.

[0137] Specifically, in the first direction X, the distance between the second light-shielding part 294a and the privacy-protecting light-emitting part 253b can be 0.5 micrometers, 0.6 micrometers, 0.7 micrometers, 0.8 micrometers, 0.9 micrometers, 1.0 micrometers, 1.1 micrometers, 1.2 micrometers, 1.3 micrometers, 1.4 micrometers, 1.5 micrometers, 1.6 micrometers, 1.7 micrometers, 1.8 micrometers, 1.9 micrometers, and 2.0 micrometers.

[0138] In some embodiments, such as Figure 8 As shown, in the second direction Y, the distance K1 between the first light-shielding part 291a and the privacy-preventing light-emitting part 253b is 0.5 micrometers to 1.5 micrometers; so that the distance between the first light-shielding part 291a and the privacy-preventing light-emitting part 253b is as small as possible, thereby improving the privacy-preventing effect.

[0139] Specifically, in the second direction Y, the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part can be 0.5 micrometers, 0.6 micrometers, 0.7 micrometers, 0.8 micrometers, 0.9 micrometers, 1.0 micrometers, 1.1 micrometers, 1.2 micrometers, 1.3 micrometers, 1.4 micrometers and 1.5 micrometers.

[0140] In some embodiments, such as Figure 8 As shown, in the second direction Y, the distance K2 between the second light-shielding part 294a and the privacy-preventing light-emitting part 253b is 0.5 micrometers to 2 micrometers, so that the distance between the second light-shielding part 294a and the privacy-preventing light-emitting part 253b is as small as possible, thereby improving the privacy-preventing effect.

[0141] Specifically, in the second direction Y, the distance between the second light-shielding part 294a and the privacy-protecting light-emitting part 253b can be 0.5 micrometers, 0.6 micrometers, 0.7 micrometers, 0.8 micrometers, 0.9 micrometers, 1.0 micrometers, 1.1 micrometers, 1.2 micrometers, 1.3 micrometers, 1.4 micrometers, 1.5 micrometers, 1.6 micrometers, 1.7 micrometers, 1.8 micrometers, 1.9 micrometers, and 2.0 micrometers.

[0142] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, a plurality of privacy-protecting sub-pixels 15 form a privacy-protecting pixel 12, and a plurality of non-privacy-protecting sub-pixels 14 form a non-privacy-protecting pixel 11. The privacy-protecting pixel 12 and the non-privacy-protecting pixel 11 are alternately arranged along the first direction X, and the privacy-protecting pixel 12 and the non-privacy-protecting pixel 11 are alternately arranged along the second direction Y, thereby improving the display effect.

[0143] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the first direction X, the width G1 of the second light-blocking portion 294a located between the privacy pixel 12 and the non-privacy pixel 11 is smaller than the width G2 of the second light-blocking portion 294a located between adjacent privacy sub-pixels 15. This makes the second light-blocking portion 294a have a better light-blocking effect on the large-angle light emission of the privacy pixel, and avoids the second light-blocking portion 294a blocking the large-angle light emission of the non-privacy pixel, thereby realizing the switching between sharing mode and privacy mode.

[0144] Specifically, since the non-spy pixel 11 needs to emit light at a wide angle, while the wide-angle light emission of the privacy pixel needs to be blocked, the width of the second light-blocking portion 294a between the privacy pixel 12 and the non-spy pixel 11 can be smaller than the width of the second light-blocking portion 294a located between adjacent privacy sub-pixels 15, thereby taking into account both blocking the wide-angle light emission of the privacy pixel and avoiding blocking the wide-angle light emission of the non-spy pixel.

[0145] In some embodiments, such as Figure 3 , Figure 4 , Figures 6 to 8As shown, in the projection on the substrate 21, in the first direction X, the distance D between the second light-shielding part 294a and the privacy light-emitting part 253b located between the privacy pixel 12 and the non-privacy pixel 11 is smaller than the distance F between the second light-shielding part 294a and the non-privacy light-emitting part 253a located between the privacy pixel 12 and the non-privacy pixel 11; thereby, the second light-shielding part 294a blocks the large-angle light emission of the privacy sub-pixel 15 and reduces the large-angle light emission of the non-privacy sub-pixel 14, thus balancing the blocking of light from the privacy sub-pixel and the light emission of the non-privacy sub-pixel, achieving both privacy and sharing effects, and improving the display effect.

[0146] Specifically, when setting the distance between the second light-shielding part 294a and the privacy-protecting light-emitting part 253b, the distance between the second light-shielding part 294a and the privacy-protecting light-emitting part 253b is made as small as possible to improve the privacy protection effect. When setting the distance between the second light-shielding part 294a and the non-privacy-protecting light-emitting part 253a, the distance between the second light-shielding part 294a and the non-privacy-protecting light-emitting part 253a is made relatively large to avoid excessive brightness attenuation in the sharing mode and improve the display effect.

[0147] In some embodiments, such as Figure 3 , Figure 8 As shown, in the first direction X, the distance between the first light-shielding part 291a and the non-privacy light-emitting part 253a is 3 micrometers to 5 micrometers, that is, the value of E is 3 micrometers to 5 micrometers; making the distance between the first light-shielding part 291a and the non-privacy light-emitting part 253a relatively large avoids excessive brightness attenuation in the sharing mode and improves the display effect.

[0148] Specifically, the distance between the first light-shielding part 291a and the non-peeping light-emitting part 253a can be 3 micrometers, 4 micrometers, and 5 micrometers.

[0149] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the second light-shielding portion 294a located between the privacy pixel 12 and the non-privacy pixel 11 includes a first segment 311 and a second segment 312. The first segment 311 is disposed between the privacy pixel 12 and the non-privacy pixel 11, and the second segment connects two adjacent first segments 311.

[0150] Specifically, the width G4 of the second segment 312 can be greater than the width G1 of the first segment 311; thereby enabling the second segment to connect better with the first segment and block the light emitted by the privacy pixel; however, the embodiments of this application are not limited to this, and the width of the second segment 312 can also be equal to the width of the first segment.

[0151] Specifically, such as Figure 3 As shown, the spacing between the second light-shielding part 294a and the privacy pixel and the non-privacy pixel is not equal, which makes the edges of two adjacent first segments 311 not on a straight line. It is necessary to use a second segment 312 to connect the adjacent first segments 311. The width of the second segment 312 is relatively large, which makes it easier to connect the first segments and avoids light leakage.

[0152] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the first segment 311 extends along the second direction Y, and the extension direction of the second segment 312 forms an acute angle with the first direction X. The extension direction of the second segment 312 forms an acute angle with the second direction Y. This allows the second segment 312 to have a gap in the direction corresponding to the non-peeping sub-pixel, preventing the second light-shielding part 294a from blocking the light of the non-peeping sub-pixel and improving the display effect.

[0153] Specifically, when setting the second light-shielding part 294a between the privacy pixel 12 and the non-privacy pixel 11, in order to balance blocking the light from the privacy pixel 12 from a wide viewing angle and not blocking the light emitted from the non-privacy pixel 11 from a wide viewing angle, the sides of two adjacent first segments 311 need to be on different straight lines, so that the distance between the first segment 311 and the privacy sub-pixel is smaller than the distance between the first segment 311 and the non-privacy sub-pixel, thereby balancing the privacy effect and the sharing display effect.

[0154] Furthermore, considering that disconnecting the two first segments 311 would cause light leakage at some angles (such as 45 degrees and 135 degrees), resulting in poor privacy protection, a second segment 312 is set to connect the adjacent first segment 311.

[0155] Furthermore, since the second segment 312 is relatively close to the non-privacy pixel, the extension direction of the second segment 312 forms an acute angle with the first direction X and an acute angle with the second direction Y, so that the second segment 312 is tilted and forms a gap in the area of ​​the second segment 312 facing the non-privacy pixel. This can reduce the obstruction of light emitted by the second segment 312 to the non-privacy pixel. Since the area of ​​the second segment 312 is reduced, the transmittance of the display panel can also be improved, thus improving the display effect.

[0156] Specifically, it can be understood that the extension direction of the second segment 312 can also form an obtuse angle with the first direction X, and the extension direction of the second segment 312 can also form an obtuse angle with the second direction Y. In this embodiment, an acute angle is used as an example for explanation. Similarly, the following embodiments are also explained using acute angles.

[0157] In some embodiments, such as Figure 3 , Figure 4 , Figures 6 to 8As shown, the light-emitting material layer 253 also includes a non-privacy light-emitting portion 253a corresponding to the non-privacy sub-pixel. In the projection on the substrate 21, in the first direction X, the distance C between the first light-shielding portion 291a and the privacy light-emitting portion 253b is smaller than the distance E between the first light-shielding portion 291a and the non-privacy light-emitting portion 253a. This allows the first light-shielding portion 291a to block the large-angle light emission of the privacy sub-pixel 15, reducing the large-angle light emission of the non-privacy sub-pixel 14 and improving the display effect.

[0158] Specifically, when setting the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part 253b, the distance between the first light-shielding part 291a and the privacy-protecting light-emitting part 253b is made as small as possible to improve the privacy protection effect. When setting the distance between the first light-shielding part 291a and the non-privacy-protecting light-emitting part 253a, the distance between the first light-shielding part 291a and the non-privacy-protecting light-emitting part 253a is made relatively large to avoid excessive brightness attenuation in the sharing mode and improve the display effect.

[0159] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the first light-shielding portion 291a located between the privacy pixel 12 and the non-privacy pixel 11 includes a light-shielding segment 315 and a first connecting segment 316. The light-shielding segment 315 is disposed between the privacy pixel 12 and the non-privacy pixel 11, and the first connecting segment 316 connects two adjacent light-shielding segments 315. The light-shielding segment 315 extends along the second direction Y, and the extension direction of the first connecting segment 316 forms an acute angle with the first direction X and the second direction Y. This ensures that the first light-shielding portion does not block the light from the non-privacy sub-pixels, thereby improving the display effect.

[0160] Specifically, when setting the first light-shielding part 291a located between the privacy pixel 12 and the non-privacy pixel 11, in order to balance blocking the light from the privacy pixel 12 from a wide viewing angle and not blocking the light emitted from the non-privacy pixel 11 from a wide viewing angle, the sides of two adjacent light-shielding sections 315 need to be on different straight lines, so that the distance between the light-shielding section 315 and the privacy sub-pixel is smaller than the distance between the light-shielding section 315 and the non-privacy sub-pixel, thereby balancing the privacy effect and the sharing display effect.

[0161] Furthermore, considering that when the two light-shielding sections 315 are disconnected, light leakage will occur at some angles (such as 45 degrees and 135 degrees), resulting in poor privacy protection, a first connecting section 316 will be set to connect the adjacent light-shielding section 315.

[0162] Furthermore, since the first connecting segment 316 is relatively close to the non-privacy sub-pixel, the extension direction of the first connecting segment 316 forms an acute angle with the first direction X and an acute angle with the second direction Y, so that the first connecting segment 316 is tilted and forms a notch in the area of ​​the first connecting segment 316 facing the non-privacy sub-pixel. This can reduce the obstruction of light emitted by the first connecting segment 316 to the non-privacy sub-pixel. Since the area of ​​the first connecting segment 316 is reduced, the transmittance of the display panel can also be improved, thereby improving the display effect.

[0163] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the first direction X, there is no second light-blocking part 294a between two adjacent non-peeping sub-pixels 14. The second light-blocking part 294a located between adjacent peeping sub-pixels 15 includes a third segment 313 and a fourth segment 314 connected together. The width of the third segment G2 is greater than the width of the fourth segment G4. This makes the viewing angle symmetry of the non-peeping sub-pixels better and blocks less light from the non-peeping sub-pixels, thus improving the display effect.

[0164] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the second direction Y, the fourth segment 314 has a notch on the side facing the non-peeping pixel 14, and the widths of the two ends of the fourth segment 314 are not equal.

[0165] Specifically, by creating a notch in the fourth segment 314 facing the non-privacy sub-pixel, the notch on the fourth segment 314 achieves a certain symmetry with the notch on the second segment 312. This results in better viewing angle symmetry for the non-privacy sub-pixel and reduces light obstruction from the non-privacy sub-pixel over its wide viewing angle, thus improving the display effect. Furthermore, the notch on the fourth segment 314 avoids the light-transmitting hole, thereby increasing the transmittance of the display panel.

[0166] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the first light-shielding portion 291a further includes a second connecting segment 317, which connects the first light-shielding portion 291a located between adjacent non-peeping sub-pixels 14 and the first light-shielding portion 291a located between adjacent peeping sub-pixels 15. In the second direction Y, the second connecting segment 317 has a notch on the side facing the non-peeping sub-pixels 14, and the widths of the two ends of the second connecting segment 317 are unequal, which makes the viewing angle symmetry of the non-peeping sub-pixels better and the light blocking of the non-peeping sub-pixels less, thus improving the display effect.

[0167] Specifically, by forming a notch in the second connecting segment 317 towards the non-privacy pixel, the notch on the second connecting segment 317 and the notch on the first connecting segment 316 can have a certain degree of symmetry. This allows the non-privacy pixel to have better viewing angle symmetry and reduces some of the obstruction of light from the non-privacy pixel at a wide viewing angle, thus improving the display effect. Furthermore, the notch on the second connecting segment 317 can avoid the light-transmitting hole, thereby increasing the transmittance of the display panel.

[0168] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, in the first direction X, the width of the first light-blocking portion 291a located between adjacent non-spy sub-pixels 14 is smaller than the width of the first light-blocking portion 291a located between adjacent spy sub-pixels 15; this makes the first light-blocking portion 291a have a better light-blocking effect on the large-angle light emission of the spy pixels, and avoids the first light-blocking portion 291a blocking the large-angle light emission of the non-spy pixels, thereby realizing the switching between sharing mode and spy mode.

[0169] Specifically, since the non-spy pixel 11 needs to emit light at a wide angle, while the wide-angle light emission of the privacy pixel needs to be blocked, the width of the first light-blocking portion 291a between the privacy sub-pixels can be smaller than the width of the first light-blocking portion 291a located between adjacent privacy pixels, thereby taking into account the blocking of the wide-angle light of the privacy sub-pixels and avoiding excessive blocking of the wide-angle light of the non-spy pixel.

[0170] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the second direction Y, the distance H between one end of the second light-shielding portion 294a located between adjacent privacy sub-pixels 15 and the privacy sub-pixel 15 is smaller than the distance I between the privacy sub-pixel 15 and the non-privacy sub-pixel 14; thereby avoiding blocking the light from the non-privacy sub-pixel at a large angle, and being able to block the light from the privacy sub-pixel to avoid bluish or pinkish discoloration.

[0171] Specifically, the distance between one end of the second light-shielding portion 294a located between adjacent privacy pixels 15 and the privacy pixel 15 may be less than or equal to half the distance between the privacy pixel 15 and the non-privacy pixel 14.

[0172] Specifically, the distance between one end of the second light-shielding portion 294a located between adjacent privacy sub-pixels 15 and the privacy sub-pixel 15 may be greater than half the distance between the privacy sub-pixel 15 and the non-privacy sub-pixel 14.

[0173] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the first direction X, the second light-shielding part 294a located between the privacy pixel 12 and the non-privacy pixel 11 includes a first segment 311 and a second segment 312. The second segment 312 connects two adjacent first segments 311. The width range G1 of the first segment 311 is 6 micrometers to 8 micrometers, thereby reducing the impact of the second light-shielding part 294a on the non-privacy pixel and improving the display effect.

[0174] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the width of the second segment ranges from 12 micrometers to 18 micrometers, which allows the second segment to connect well with the first segment and block the light emitted by the privacy pixel.

[0175] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, in the first direction X, the second light-shielding portion 294a located between adjacent privacy sub-pixels 15 includes a third segment 313 and a fourth segment 314 connected together. The width range G2 of the third segment 313 is 12 micrometers to 18 micrometers, and the shape of the fourth segment 314 is trapezoidal. The width range G3 of one end of the fourth segment 314 is 8 micrometers to 17 micrometers. This makes the second light-shielding portion 294a have a better blocking effect on the light emitted by the privacy sub-pixels, and reduces the blocking effect of the second light-shielding portion 294a on the light emitted by non-privacy sub-pixels, thus balancing the privacy effect and the display effect.

[0176] In some embodiments, such as Figure 8 As shown, in the second direction Y, the width range G5 of the second light-shielding portion 294a located between the privacy pixel 12 and the non-privacy pixel 11 is 6 micrometers to 8 micrometers; thereby reducing the influence of the second light-shielding portion 294a on the non-privacy pixel and improving the display effect.

[0177] Specifically, in the first direction X, the width of the first light-blocking portion located between the privacy sub-pixels is greater than the width of the first light-blocking portion located between the non-privacy sub-pixels.

[0178] In some embodiments, the thickness of the first light-shielding layer 291 ranges from 0.9 micrometers to 1.2 micrometers, enabling the first light-shielding layer 291 to block light from a wide viewing angle.

[0179] In some embodiments, the thickness of the second light-shielding layer ranges from 0.9 micrometers to 1.2 micrometers, enabling the second light-shielding layer 294 to block light from a wide viewing angle.

[0180] In some embodiments, such as Figure 4 As shown, the display panel 1 also includes a first planarization layer 28, which is disposed between the first light-shielding layer 291 and the light-emitting functional layer 25. The thickness of the first planarization layer 28 ranges from 4 micrometers to 6 micrometers. This can raise the first light-shielding layer 291 and the second light-shielding layer 294, blocking light from a wide viewing angle and achieving a privacy protection effect. Furthermore, the thickness of the organic layer can be reduced while keeping the height of the first light-shielding layer 291 and the second light-shielding layer 294 unchanged.

[0181] In some embodiments, such as Figure 4 As shown, the display panel 1 further includes a second planarization layer 292 and a third planarization layer 293. The second planarization layer 292 is disposed between the first light-shielding layer 291 and the second light-shielding layer 294, and the third planarization layer 293 is located between the second planarization layer 292 and the second light-shielding layer 294. The thickness of the second planarization layer 292 ranges from 4 micrometers to 5 micrometers, and the thickness of the third planarization layer 293 ranges from 3 micrometers to 4 micrometers. This ensures privacy protection and reduces light leakage between the first light-shielding layer and the second light-shielding layer.

[0182] Specifically, the thickness of the second planarization layer 292 and the third planarization layer 293 ranges from 7 micrometers to 9 micrometers.

[0183] Specifically, the thickness of the first inorganic encapsulation layer 261 ranges from 1 micrometer to 1.5 micrometers; the thickness of the organic layer 262 ranges from 7 micrometers to 11 micrometers; and the thickness of the second inorganic encapsulation layer 263 ranges from 0.6 micrometers to 0.8 micrometers.

[0184] Specifically, the materials of the first touch insulating layer 271, the second touch insulating layer 273, and the third touch insulating layer can be silicon nitride or silicon oxynitride; the thickness of the first touch insulating layer 271, the second touch insulating layer 273, and the third touch insulating layer ranges from 0.2 micrometers to 0.4 micrometers.

[0185] In some embodiments, the angle of light blocked by the first light-shielding layer 291 is greater than the angle of light blocked by the second light-shielding layer 294.

[0186] Specifically, the thickness of the fourth planarization layer 295 ranges from 3 micrometers to 5 micrometers.

[0187] Specifically, the width of the first non-peeping sub-pixel 111 in the second direction Y ranges from 10 micrometers to 14 micrometers, the width of the second non-peeping sub-pixel 112 in the second direction Y ranges from 10 micrometers to 14 micrometers, and the width of the third non-peeping sub-pixel 113 in the second direction Y ranges from 24 micrometers to 28 micrometers; the width of the first privacy sub-pixel 121 in the second direction Y ranges from 10 micrometers to 14 micrometers, the width of the second privacy sub-pixel 122 in the second direction Y ranges from 10 micrometers to 14 micrometers, and the width of the third privacy sub-pixel 123 in the second direction Y ranges from 24 micrometers to 28 micrometers.

[0188] In some embodiments, the width of the privacy sub-pixel in the first direction is equal to the width of the non-privacy sub-pixel in the first direction.

[0189] In some embodiments, the width of the first privacy pixel 121 in the first direction X is equal to the width of the third privacy pixel 123 in the first direction X, and the width of the second privacy pixel 122 in the first direction X is equal to the width of the third privacy pixel 123 in the first direction X; thereby improving the privacy protection effect.

[0190] In some embodiments, the width of the first non-peeping sub-pixel 111 in the first direction X is equal to the width of the second non-peeping sub-pixel 112 in the first direction X, and the width of the third non-peeping sub-pixel 113 in the first direction X is equal to the width of the second non-peeping sub-pixel 112 in the first direction X.

[0191] 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.

[0192] Specifically, the shape of the privacy pixel can be square, rectangular, rounded rectangle, circular, elliptical, etc. Correspondingly, the shape of the first light-blocking part 291a and the second light-blocking part 294a on the side opposite to the privacy pixel is adapted. For example, the shape of the privacy pixel is circular, and the side of the first light-blocking part 291a and the second light-blocking part 294a near the privacy pixel is arc-shaped. This will not be elaborated further here.

[0193] Specifically, the shape of non-peeping pixels can be square, rectangle, rounded rectangle, circle, ellipse, etc.

[0194] 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.

[0195] Specifically, the above embodiments have described the display panel in detail from aspects such as pixel arrangement and film structure. It is understood that when there is no conflict between the embodiments, the embodiments can be combined. For example, in the first direction, the distance between the first light-shielding part and the privacy-proof light-emitting part is smaller than the distance between the first light-shielding part and the non-privacy-proof light-emitting part; and / or, in the first direction, the distance between the second light-shielding part located between the privacy-proof pixel and the non-privacy-proof pixel and the privacy-proof light-emitting part is smaller than the distance between the second light-shielding part located between the privacy-proof pixel and the non-privacy-proof pixel and the non-privacy-proof light-emitting part.

[0196] Specifically, with Figure 1 Taking the comparison display device shown as an example, the brightness at different positions was tested, and the results were obtained. Figure 10 ,by Figure 3 Taking the displayed panel as an example, the brightness of the display panel at different positions was tested, and the results were obtained. Figure 11 , Figure 10 , Figure 11 The horizontal axis represents the viewing angle, which can be the left, right, top, or bottom view. 0 indicates a direct view of the display panel, and 20 indicates a viewing angle of 20 degrees. The vertical axis represents the ratio of brightness to the viewing angle. The brightness at the viewing angle is 1, meaning the brightness at 0 degrees is 100% of the brightness at the viewing angle, and 80% means the brightness is 80% of the brightness at the viewing angle.

[0197] from Figure 10 As can be seen, Figure 10 Curve 1 in the diagram represents both the brightness curves from different viewing angles on the left and right sides of the display device, and the brightness curves from different viewing angles on the top and bottom sides of the display device. Figure 10 As can be seen, the brightness decays at the same rate from different angles. When users view the comparison display device from a non-direct viewing angle, the brightness decays rapidly, resulting in a poor display effect.

[0198] from Figure 11 As can be seen, Figure 11 Curve 1 in the diagram represents the brightness curves of the display panel from different viewing angles along the first direction, and curve 2 represents the brightness curves of the display panel from different viewing angles along the second direction. Figure 11As can be seen, the brightness decay in the second direction of the display panel is slower than that in the first direction. When the user holds the phone in privacy mode, even if there is a certain viewing angle between the user and the display panel, it is always an angle in the second direction. The brightness decay is slow and will not affect the display effect, thus improving the display effect.
