Description

Technical Field

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

[0002] OLED (Organic Light-Emitting Diode) displays are widely used due to their self-emissive nature and flexibility. To achieve privacy protection, existing OLED displays use both privacy pixels and non-privacy pixels. Privacy protection works by blocking light from the privacy pixels' wide viewing angle and combining this with different display modes. Furthermore, to reduce manufacturing costs and improve efficiency, inkjet printing is used to form OLED displays. However, inkjet printing can result in excessively large openings for the privacy pixels, leading to poor privacy protection.

[0003] Therefore, existing OLED display devices have a technical problem where the openings of the privacy pixels are too large, resulting in poor privacy protection. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the technical problem that existing OLED display devices have excessively large openings for privacy pixels, resulting in poor privacy protection.

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, comprising a plurality of privacy-protecting sub-pixels and a plurality of non-privacy-protecting sub-pixels, wherein the privacy-protecting sub-pixels and the non-privacy-protecting sub-pixels of the same emission color are alternately arranged along a first direction, and the privacy-protecting sub-pixels of different emission colors are arranged in the same row along a second direction, and the non-privacy-protecting sub-pixels of different emission colors are arranged in the same row along the second direction, wherein the first direction and the second direction are different, and the display panel comprises: Substrate; A pixel definition layer is disposed on one side of the substrate, the pixel definition layer including a first pixel opening corresponding to the privacy sub-pixel and a second pixel opening corresponding to the non-privacy sub-pixel; Wherein, the width of the first pixel opening along the second direction is smaller than the width of the second pixel opening along the second direction.

[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 reduces the area of ​​the privacy sub-pixel by making the pixel definition layer include a first pixel opening corresponding to the privacy sub-pixel and a second pixel opening corresponding to the non-privacy sub-pixel, and making the width of the first pixel opening along the second direction smaller than the width of the second pixel opening along the second direction. The large-angle light emission of the privacy sub-pixel is blocked by the pixel definition layer, thereby reducing the light emission angle of the privacy sub-pixel and improving the privacy effect.

[0026] 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.

[0027] To illustrate the principle behind the technical problems in the embodiments of 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. Figures 1 to 3 As shown, Figure 2 for Figure 1 The comparison shows exploded views of the various film layers of the device. Figure 2 (a) in the middle is Figure 1 The comparison display shows an exploded view of the first pixel defining the film of the device. Figure 2 (b) in the middle is Figure 1 An exploded view of the second pixel definition film of the contrast display device. Figure 2 (c) in the middle is Figure 1 The comparison shows an exploded view of the light-emitting film of the display device. Figure 2 (d) in the middle is Figure 1 An exploded view of the first light-shielding film of the contrast display device. Figure 2 (e) in the middle is Figure 1 An exploded view of the second light-shielding film of the contrast display device. Figure 3 for Figure 1 The comparison shows cross-sectional schematic diagrams of different positions of the display device. Figure 3 (a) in the middle is Figure 1 A schematic diagram of the A1-A2 cross-section of the display device. Figure 3 (b) in the middle is Figure 1 A schematic diagram of the B1-B2 cross-section of the contrast display device. Figure 3 (c) in the middle is Figure 1 A schematic diagram of the C1-C2 cross section of the contrast display device.

[0028] like Figures 1 to 3 As shown, the contrast display device includes a first pixel definition film 131, a second pixel definition film 132, a light-emitting film 133, an encapsulation film 134, a first planarization film, a first light-blocking film 135, a second planarization film 136, and a second light-blocking film 137. The contrast display device may also include a color resist film 138. Specifically, the light-emitting film 133 includes red privacy light-emitting portions 134a, green privacy light-emitting portions 134b, blue privacy light-emitting portions 134c, red non-privacy light-emitting portions 133a, green non-privacy light-emitting portions 133b, and blue non-privacy light-emitting portions 133c corresponding to the red privacy sub-pixel 121, green privacy sub-pixel 122, blue privacy sub-pixel 123, red non-privacy light-emitting portions 111, green non-privacy light-emitting portions 112, and blue non-privacy light-emitting portions 113.

[0029] To improve the fabrication efficiency of contrast display devices, such as Figure 1 , Figure 2 As shown, inkjet printing is used to prepare a contrast display device. When inkjet printing is used, the first pixel definition film 131 includes a plurality of horizontal first pixel limiting portions 131a, and the second pixel definition film 132 includes a plurality of vertical second pixel limiting portions 131b. The height of the second pixel limiting portion 131b is greater than the height of the first pixel limiting portion 131a, so that the ink of inkjet printing can flow between adjacent sub-pixels in the same column.

[0030] Therefore, as Figure 1 As shown, red privacy pixel 121 and red non-privacy pixel 111 are arranged in the same column, green privacy pixel 122 and green non-privacy pixel 112 are arranged in the same column, and blue privacy pixel 123 and blue non-privacy pixel 113 are arranged in the same column.

[0031] Meanwhile, in order to balance the wide-angle light emission in sharing mode and the privacy protection effect in privacy mode, the area of ​​the privacy sub-pixel will be smaller than the area of ​​the non-privacy sub-pixel. Specifically, the width of the light-emitting part of the privacy sub-pixel of the same light-emitting color will be equal to the width of the light-emitting part of the non-privacy sub-pixel, and the length of the light-emitting part of the privacy sub-pixel of the same light-emitting color will be less than the length of the light-emitting part of the non-privacy sub-pixel. For example, the width L1 of the red privacy light-emitting part 134a will be equal to the width L2 of the red non-privacy light-emitting part 133a, and the length H1 of the red privacy light-emitting part 134a will be less than the length H2 of the red non-privacy light-emitting part 133a.

[0032] Specifically, such as Figures 1 to 3 As shown, the width L3 of the first hole 135a of the first light-shielding film 135 is equal to the width L4 of the second hole 137a of the second light-shielding film 137, the width L3 of the first hole 135a of the first light-shielding film 135 is equal to the length H3 of the first hole 135a, the width L4 of the second hole 137a is equal to the length H4 of the second hole 137a, and the width L3 of the first hole 135a of the first light-shielding film 135 is smaller than the width L1 of the red privacy light-emitting part 134a, and the length H3 of the first hole 135a is smaller than the length H1 of the red privacy light-emitting part 134a, thereby further reducing the light-emitting area of ​​the privacy sub-pixel and realizing privacy display. The size of the hole corresponding to the non-privacy sub-pixel in the first light-shielding film 135 is the same as the size of the hole in the pixel definition film, realizing shared display.

[0033] But from Figures 1 to 3 As can be seen, because inkjet printing requires printing sub-pixels of the same luminous color vertically, the width of the privacy-protected luminous portion and the non-privacy-protected luminous portion are equal. This results in the privacy-protected sub-pixels emitting light at excessively large angles to both sides, leading to poor privacy protection. Furthermore, a large area of ​​the privacy-protected sub-pixels is blocked by the light-shielding film, resulting in lower power consumption. Therefore, existing OLED display devices suffer from the technical problem of excessively large openings in the privacy-protected pixels, leading to poor privacy protection.

[0034] This application provides a display panel and a display device to address the aforementioned technical problems.

[0035] like Figure 4 As shown, this application embodiment provides a display panel 2, which includes a display area 201 and a non-display area 202. Sub-pixels can be set in the display area 201, and structures such as gate driving circuits and bonding terminals can be set in the non-display area 202.

[0036] Specifically, Figure 4The example described uses a non-display area 202 surrounding a display area 201, but this embodiment is not limited to this. The non-display area 202 can be located on one, two, or three sides of the display area 201. 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 201, which may or may not be displayed. When the display panel in this embodiment uses a full-screen display, the non-display area 202 can be bent or folded to the back of the display panel 2.

[0037] Specifically, the non-display area 202 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 201. The left and right border areas are disposed on both sides of the display area 201 along a second direction X, and the upper and lower border areas are disposed on both sides of the display area 201 along a first direction Y. The angle between the second direction X and the first direction Y is greater than 0 and less than or equal to 90 degrees, for example, it can be an angle of 89 degrees, 85 degrees, 80 degrees, etc. Gate driving circuits can be disposed in the left and right border areas to input signals, and bonding terminals can be disposed in the lower border area for bonding driving chips. The lower border area includes a bonding area 202a.

[0038] Specifically, such as Figure 5 , Figure 13 As shown, the display area 201 is provided with multiple non-peeping pixels 31 and peeping pixels 32. The non-peeping pixels 31 may include a first non-peeping sub-pixel 311, a second non-peeping sub-pixel 312 and a third non-peeping sub-pixel 313 with different light emission colors. The peeping pixels 32 may include a first peeping sub-pixel 321, a second peeping sub-pixel 322 and a third peeping sub-pixel 323 with different light emission colors.

[0039] Specifically, multiple non-peeping pixels 34 and multiple privacy pixels 35 can be set in the display area 201. The multiple non-peeping pixels 34 may include a first non-peeping pixel 311, a second non-peeping pixel 312 and a third non-peeping pixel 313 with different light emission colors. The privacy pixels 35 may include a first privacy pixel 321, a second privacy pixel 322 and a third privacy pixel 323 with different light emission colors.

[0040] Specifically, the emission color of one of the first non-privacy pixel 311, the second non-privacy pixel 312, and the third non-privacy pixel 313 is one of red, green, and blue; the emission color of another of the first non-privacy pixel 311, the second non-privacy pixel 312, and the third non-privacy pixel 313 is one of red, green, and blue; and the emission color of the remaining one of the first non-privacy pixel 311, the second non-privacy pixel 312, and the third non-privacy pixel 313 is the remaining one of red, green, and blue. For example, the emission colors of the first non-privacy pixel 311, the second non-privacy pixel 312, and the third non-privacy pixel 313 are red, green, or blue, respectively. Of course, the emission colors of the first non-privacy pixel 311, the second non-privacy pixel 312, and the third non-privacy pixel 313 can be other combinations, which will not be elaborated here.

[0041] Specifically, one of the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323 emits light in a color that is one of red, green, and blue; another of the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323 emits light in a color that is one of red, green, and blue; and the remaining one of the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323 emits light in a color that is one of red, green, and blue. For example, the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323 emit light in a color that is red, green, or blue, respectively. Of course, the light emission colors of the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323 can be other combinations, which will not be elaborated here.

[0042] Specifically, the emission colors of the first non-peeping pixel 311, the second non-peeping pixel 312, and the third non-peeping pixel 313 can be the same as those of the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323, respectively.

[0043] Specifically, by making the light emission colors of the first non-peeping sub-pixel 311, the second non-peeping sub-pixel 312, and the third non-peeping sub-pixel 313 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 321, the second privacy sub-pixel 322, and the third privacy sub-pixel 323 different, the light emission colors of the light-emitting parts corresponding to each privacy sub-pixel can be different.

[0044] Specifically, the arrangement of sub-pixels in non-spy pixel 31 and spy pixel 32 is not limited in this embodiment. The following embodiments use realRGB as an example for illustration.

[0045] Specifically, the arrangement of the non-spy pixel 31 and the spy pixel 32 is not limited in this application embodiment. In the following embodiment, some arrangement of the non-spy pixel 31 and the spy pixel 32 will be used as examples for illustration.

[0046] Specifically, within the display area 201, multiple privacy pixels 32 can be arranged in the same row along the second direction X, multiple non-privacy pixels 31 can be arranged in the same row along the second direction X, and privacy pixels 32 and non-privacy pixels 31 can be alternately arranged along the first direction Y.

[0047] Specifically, the first non-peeping pixel 311 and the first peeping pixel 321 can be alternately arranged in the same column along the first direction Y, the second non-peeping pixel 312 and the second peeping pixel 322 can be alternately arranged in the same column along the first direction Y, the third non-peeping pixel 313 and the third peeping pixel 323 can be alternately arranged in the same column along the first direction Y, the first non-peeping pixel 311, the second non-peeping pixel 312, and the third non-peeping pixel 313 can be alternately arranged along the second direction X, and the first peeping pixel 321, the second peeping pixel 322, and the third peeping pixel 323 can be alternately arranged along the second direction X.

[0048] Specifically, such as Figures 9 to 12 , Figure 14 , Figure 15 As shown, the display panel 2 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.

[0049] Specifically, the substrate 21 can be a flexible substrate or a rigid glass substrate.

[0050] Specifically, the display panel 2 can be formed by inkjet printing to create the light-emitting functional layer 25, or by vapor deposition to create the light-emitting functional layer 25.

[0051] Specifically, such as Figures 9 to 12 , Figure 14 , Figure 15 As shown, the display panel 2 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.

[0052] Specifically, the display panel 2 may also include a dimming function layer, which is located on the side of the touch layer away from the encapsulation layer.

[0053] 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.

[0054] 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.

[0055] Specifically, such as Figures 9 to 11 , Figure 14 , Figure 15 As shown, the display panel 2 also includes a first flattening layer 28, a first light-shielding layer 291, a second flattening layer 292, a second light-shielding layer 294, and a third flattening layer 295 arranged sequentially.

[0056] Specifically, the display panel 2 may also include a fourth planarization layer, which is disposed between the second planarization layer 292 and the second light-shielding layer 294.

[0057] 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.

[0058] Specifically, the first planarization layer 28 can serve as the first microlens layer.

[0059] Specifically, such as Figure 5 , Figures 9 to 11 , Figure 14 , Figure 15 As shown, the display panel 2 may also include a color resist layer 296, which is disposed between the first light-shielding layer 291 and the second planarization layer 292.

[0060] Specifically, the color resist layer 296 may include a first color resist 296a, a second color resist (not shown), a third color resist (not shown), a fourth color resist 296d, a fifth color resist (not shown), and a sixth color resist (not shown) corresponding to the first non-peeping pixel 311, the second non-peeping pixel 312, the third non-peeping pixel 313, the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323, respectively. The first color resist, the second color resist, and the third color resist may have the same light-transmitting color as the fourth color resist, the fifth color resist, and the sixth color resist, respectively, and the first color resist, the second color resist, and the third color resist may be prepared simultaneously with the fourth color resist, the fifth color resist, and the sixth color resist, respectively.

[0061] Specifically, the display panel 2 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.

[0062] 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.

[0063] Specifically, such as Figure 12 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.

[0064] Specifically, the active layer can be made of silicon semiconductor, and the semiconductor layer can be made of oxide semiconductor.

[0065] Specifically, Figure 12 The driving circuit layer 22 shown in the illustration is illustrated with an example of one active layer, one 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 only one active layer or one semiconductor layer. The thin-film transistor may be a top-gate transistor or a bottom-gate transistor. It may be a low-temperature polycrystalline silicon thin-film transistor or a polycrystalline silicon thin-film transistor formed by solid-state crystallization. The driving circuit layer 22 may have one gate layer or two gate layers. When there are two gate layers, the two gate layers are disposed on both sides of the active layer or on the same side of the active layer. One gate layer forms the gate, and the other gate layer forms a capacitor and / or a signal line. Alternatively, the driving circuit layer 22 may include one active layer, and the driving circuit layer 22 may also have one or three source-drain layers. The film layer structure of the driving circuit layer 22 described in the embodiments of this application is only an example. The structure of the driving circuit layer 22 in the embodiments of this application may also be other structures, which will not be described in detail here.

[0066] Specifically, such as Figure 12 As shown, the light-emitting functional layer 25 includes a pixel electrode layer 251, a pixel definition layer 25a, a light-emitting material layer 253, and a common electrode layer 254.

[0067] Specifically, the pixel definition layer 25a may include a first pixel definition layer 252 and a second pixel definition layer 255.

[0068] Specifically, the materials of the first pixel definition layer 252 and the second pixel definition layer 255 can be the same, or they can be made of different materials. For example, the light transmittance of the first pixel definition layer 252 can be greater than that of the second pixel definition layer 255. Both the first pixel definition layer 252 and the second pixel definition layer 255 can be formed using light-transmitting photoresist, the difference being that the second pixel definition layer 255 contains light-blocking material. The hydrophilicity of the first pixel definition layer 252 can be greater than that of the second pixel definition layer 255.

[0069] Specifically, when the material of the pixel definition layer 25a contains a light-shielding material, a third light-shielding layer and a color resist layer can be used, or a first light-shielding layer combined with a color resist layer can be used; when the material of the pixel definition layer 25a is a transparent material, a polarizer can be used to reduce reflection.

[0070] Specifically, the encapsulation layer 26 may include a first inorganic encapsulation layer, an organic layer, and a second inorganic encapsulation layer.

[0071] Specifically, such as Figure 12 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.

[0072] Specifically, the pixel definition layer 25a includes multiple openings corresponding to the first non-peeping pixel 311, the second non-peeping pixel 312, and the third non-peeping pixel 313, respectively, and the area of ​​each opening may be the same or different.

[0073] Specifically, the pixel definition layer 25a includes multiple openings corresponding to the first privacy pixel 321, the second privacy pixel 322, and the third privacy pixel 323, respectively, and the area of ​​each opening may be the same or different.

[0074] Specifically, for ease of explanation, Figures 9 to 11 , Figure 14 , Figure 15 The specific structure of the touch layer 27 is not shown.

[0075] In some embodiments, when the display panel 2 is configured in sharing mode, both the non-spy pixel 31 and the privacy pixel 32 emit light; when the display panel 2 is configured in privacy mode, the non-spy pixel 31 does not emit light, and the privacy pixel 32 emits light.

[0076] Specifically, when the display panel 2 is configured in sharing mode, the non-peeping pixel 31 emits light, while the peeping pixel 32 does not emit light.

[0077] In some embodiments, in any direction, at a viewing angle of 30 degrees to 45 degrees, the brightness of the privacy pixel 32 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 31 is 20% to 30% of the brightness of the normal viewing angle (which can be considered as a 0-degree viewing angle).

[0078] like Figures 4 to 15 As shown, this application embodiment provides a display panel 2, which includes a plurality of privacy sub-pixels 35 and a plurality of non-privacy sub-pixels 34. Privacy sub-pixels 35 and non-privacy sub-pixels 34 of the same emission color are alternately arranged along a first direction Y. The display panel 2 includes a substrate 21 and a pixel definition layer 25a. The pixel definition layer 25a is disposed on one side of the substrate 21. The pixel definition layer 25a includes a first pixel opening 411 corresponding to the privacy sub-pixels 35 and a second pixel opening 412 corresponding to the non-privacy sub-pixels 34. Wherein, the width K1 of the first pixel opening 411 along the second direction X is less than the width K2 of the second pixel opening 412 along the second direction X; the angle between the first direction Y and the second direction X is greater than 0 and less than or equal to 90 degrees.

[0079] like Figures 4 to 15 As shown, this application embodiment provides a display panel 2, which includes a plurality of privacy sub-pixels 35 and a plurality of non-privacy sub-pixels 34. Privacy sub-pixels 35 and non-privacy sub-pixels 34 of the same emission color are alternately arranged along a first direction Y. Privacy sub-pixels 35 of different emission colors are arranged in the same row along a second direction X. The first direction Y is different from the second direction X. Non-privacy sub-pixels 34 of different emission colors are arranged in the same row along the second direction X. The display panel 2 includes a substrate 21 and a pixel definition layer 25a. The pixel definition layer 25a is disposed on one side of the substrate 21. The pixel definition layer 25a includes a first pixel opening 411 corresponding to the privacy sub-pixels 35 and a second pixel opening 412 corresponding to the non-privacy sub-pixels 34. Wherein, the width K1 of the first pixel opening 411 along the second direction X is smaller than the width K2 of the second pixel opening 412 along the second direction X.

[0080] This application embodiment provides a display panel; the display panel 2 includes a pixel definition layer 25a comprising a first pixel opening 411 corresponding to a privacy sub-pixel 35 and a second pixel opening 412 corresponding to a non-privacy sub-pixel 34, and the width of the first pixel opening 411 along the second direction X is smaller than the width of the second pixel opening 412 along the second direction X, thereby reducing the area of ​​the privacy sub-pixel. The pixel definition layer blocks the large-angle light emission of the privacy sub-pixel, reducing the light emission angle of the privacy sub-pixel, thereby improving the privacy effect.

[0081] Specifically, the angle between the first direction Y and the second direction X is greater than 0 and less than or equal to 90 degrees. For example, the angle between the first direction Y and the second direction X is 89 degrees, 85 degrees, 80 degrees, 75 degrees, etc.

[0082] Specifically, compared to the situation in contrast display devices where inkjet printing of sub-pixels of the same luminous color results in equal widths for each sub-pixel, leading to poor privacy protection and high power consumption, this embodiment reduces the light emission angle of the privacy-protecting sub-pixels by making the width of the first pixel opening 411 along the second direction smaller than the width of the second pixel opening 412 along the second direction. This improves the privacy protection effect, reduces power consumption, and still allows the display panel to be formed using inkjet printing.

[0083] In some embodiments, such as Figures 5 to 13 As shown, the pixel definition layer 25a includes a first pixel definition layer 252 and a second pixel definition layer 255. The first pixel definition layer 252 includes a plurality of first pixel definition portions 252a, which are spaced apart along the first direction Y. The second pixel definition layer 255 is disposed on the side of the first pixel definition layer 252 away from the substrate 21, and the second pixel definition layer 255 includes a plurality of second pixel definition portions 255a, which are spaced apart along the second direction X. In this design, at least one of the first pixel definition layer 252 and the second pixel definition layer 255 includes an extension portion 252b. The boundary of the extension portion 252b is located on the side of the second pixel definition portion 255a near the privacy sub-pixel 35. The extension portion 252b and the adjacent first pixel definition portion 252a enclose each other to form the first pixel opening 411. By including the extension portion 252b in at least one of the first pixel definition layer 252 and the second pixel definition layer 255, and by having the extension portion 252b and the adjacent first pixel definition portion 252a enclose each other to form the first pixel opening 411, the width of the first pixel opening 411 along the second direction can be reduced, thereby reducing the area of ​​the privacy sub-pixel, improving the privacy effect, and reducing power consumption.

[0084] Specifically, when determining the width of each opening or structure, the same reference is used to determine the width of each opening or structure. For example, the width of the lower side of the opening is used as the width of the opening, or the width of the center line of the opening is used as the width of the opening.

[0085] Specifically, the second pixel opening 412 is formed by the first pixel defining part 252a and the second pixel defining part 255a.

[0086] In some embodiments, such as Figures 5 to 8 As shown, the first pixel definition layer 252 includes the extension portion 252b, which extends along the first direction Y and is spaced apart along the second direction X. The extension portion 252b connects two adjacent first pixel definition portions 252a. By including the extension portion 252b in the first pixel definition layer 252, and connecting the extension portion 252b to adjacent first pixel definition portions 252a, the width of the first pixel opening 411 can be reduced, thereby reducing the area of ​​the privacy sub-pixel and improving the privacy effect.

[0087] Specifically, compared to the contrast display device where adjacent first pixel definition portions 252a are spaced apart, in some embodiments of this application, the extension portion 252b is connected to the adjacent first pixel definition portions 252a, and the light-emitting area of ​​the privacy sub-pixel is reduced by the extension portion 252b, thereby improving the privacy effect.

[0088] Specifically, when the extension 252b is formed using the first pixel definition layer 252, during inkjet printing to form the luminescent material, the ink flows above the extension 252b and the first pixel definition layer 252a, thereby improving the leveling of the luminescent material and enhancing the display effect.

[0089] In some embodiments, such as Figure 5 , Figure 6 As shown, the first pixel definition portions 252a located on both sides of the privacy sub-pixel 35 are connected by the extension portion 252b, and the first pixel definition portions 252a located on both sides of the non-privacy sub-pixel 34 are spaced apart. By connecting the first pixel definition portions 252a located on both sides of the privacy sub-pixel 35 by the extension portion 252b, the area of ​​the privacy sub-pixel can be reduced, thereby improving the privacy effect. Furthermore, by spaced apart the first pixel definition portions 252a on both sides of the non-privacy sub-pixel 34, the area of ​​the non-privacy sub-pixel is larger, and the light emission angle is larger, which can improve the wide viewing angle effect in the sharing mode.

[0090] Specifically, such as Figure 6As shown in (a), the first pixel definition portions 252a on both sides of the privacy pixel 35 are connected by the extension portion 252b, while the first pixel definition portions 252a on both sides of the non-privacy pixel 34 are not connected. This allows for differentiation of the opening areas of the privacy pixel 35 and the non-privacy pixel 34, balancing privacy protection and wide viewing angle in sharing mode, while still allowing the display panel to be formed using inkjet printing.

[0091] In some embodiments, such as Figure 13 As shown, the second pixel definition layer 255 includes the extension portion 252b, which is connected to the second pixel definition portion 255a and disposed on both sides of the second pixel definition portion 255a along the second direction X. By including the extension portion 252b in the second pixel definition layer 255 and connecting the extension portion 252b to the second pixel definition portion 255a, the width of the first pixel opening 411 can be reduced through the extension portion 252b, thereby reducing the area of ​​the privacy sub-pixel and improving the privacy effect.

[0092] Specifically, compared to the contrast display device where adjacent second pixel definition portions 255a are spaced apart and the widths of each portion of the second pixel definition portion 255a are equal, in some embodiments of this application, by connecting the extension portion 252b to the second pixel definition portion 255a, the width of the area in the second pixel definition layer with the extension portion 252b is greater than the width of the area without the extension portion 252b. The extension portion 252b reduces the light-emitting area of ​​the privacy sub-pixel, thereby improving the privacy effect.

[0093] Specifically, when the extension 252b is formed using the second pixel definition layer 255, the viewing angle of the privacy sub-pixel can be narrowed through the extension 252b, thereby improving the privacy effect.

[0094] In some embodiments, such as Figure 13 As shown, the projection of the extension 252b on the substrate 21 does not overlap with the projection of the first pixel definition portion 252a on the substrate 21. By ensuring that the projections of the extension 252b and the first pixel definition portion 252a on the substrate 21 do not overlap, it is possible to avoid the first pixel definition portion 252a and the second pixel definition portion 255a stacking in the middle area, which would increase the difficulty of ink flow, and also avoid reducing the area of ​​the non-peeping sub-pixels, thereby balancing the privacy effect and the wide viewing angle effect in the sharing mode.

[0095] Specifically, in the projection on the substrate, the two ends of the extension 252b can contact the edge of the adjacent first pixel definition portion 252a.

[0096] In some embodiments, the extension 252b includes a first extension and a second extension, the first pixel definition layer 252 includes the first extension, and the second pixel definition layer 255 includes the second extension. The first pixel opening can be reduced by the first extension and the second extension, thereby achieving both privacy protection and a wide viewing angle in sharing mode.

[0097] Specifically, the first extension and the second extension can be disposed on both sides of the privacy pixel, or the projections of the first extension and the second extension on the substrate can overlap.

[0098] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the display panel 2 further includes a first light-shielding layer 291, which is disposed on the side of the pixel definition layer 25a away from the substrate 21. The first light-shielding layer 291 includes a first light-shielding opening 421 corresponding to the privacy sub-pixel 35. Wherein, the width K3 of the first light-shielding opening 421 along the second direction X is smaller than the width K1 of the first pixel opening 411 along the second direction X. By making the width of the first light-shielding opening 421 along the second direction X smaller than the width of the first pixel opening 411 along the second direction X, the light emission angle of the privacy sub-pixel can be further reduced, thereby improving the privacy effect.

[0099] Specifically, such as Figure 9 As shown, the width of the first light-shielding opening 421 along the second direction X is smaller than the width of the first pixel opening 411 along the second direction X. This allows light emitted from the light-emitting material to be blocked by the first light-shielding layer, thereby reducing the light emission angle of the privacy sub-pixel and improving the privacy effect.

[0100] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the display panel 2 further includes a second light-shielding layer 294, which is disposed on the side of the first light-shielding layer 291 away from the substrate 21. The second light-shielding layer 294 includes a second light-shielding opening 422 corresponding to the privacy pixel 35. Wherein, the width K4 of the second light-shielding opening 422 along the second direction X is smaller than the width K1 of the first pixel opening 411 along the second direction X. By making the width of the second light-shielding opening 422 along the second direction X smaller than the width of the first pixel opening 411 along the second direction X, the light emission angle of the privacy sub-pixel can be further reduced, thereby improving the privacy effect.

[0101] Specifically, such as Figure 9As shown, the width of the second light-shielding opening 422 along the second direction X is smaller than the width of the first pixel opening 411 along the second direction X. This allows light emitted from the light-emitting material to be blocked by the second light-shielding layer, thereby reducing the light emission angle of the privacy sub-pixel and improving the privacy effect.

[0102] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the width K4 of the second light-shielding opening 422 along the second direction X is smaller than the width K3 of the first light-shielding opening 421 along the second direction X. By making the width of the second light-shielding opening 422 along the second direction X smaller than the width K3 of the first light-shielding opening 421 along the second direction X, the light emission angle of the privacy sub-pixel can be further reduced, thereby improving the privacy effect.

[0103] Specifically, such as Figure 9 As shown, the widths of the first pixel opening 411 along the second direction X, the first light-blocking opening 421 along the second direction X, and the second light-blocking opening 422 along the second direction X decrease sequentially, thereby reducing the angle of light emitted by the privacy sub-pixel, thus improving the light-blocking effect and the privacy protection effect.

[0104] In some embodiments, such as Figure 15 As shown, the pixel definition layer 25a includes a first pixel definition layer 252 and a second pixel definition layer 255. The second pixel definition layer 255 is disposed on the side of the first pixel definition layer 252 away from the substrate 21. The second pixel definition layer 255 includes a plurality of second pixel definition portions 255a, which are spaced apart along the second direction X. The display panel 2 also includes a first light-shielding layer 291, which is disposed on the side of the pixel definition layer 25a away from the substrate 21. The first light-shielding layer 291 includes a first light-shielding opening 421 corresponding to the privacy pixel 35. The width K3 of the first light-shielding opening 421 along the second direction X is greater than the spacing K6 between adjacent second pixel definition portions 255a.

[0105] Specifically, by making the width of the first light-shielding opening 421 along the second direction X greater than the spacing between adjacent second pixel definition portions 255a, the light-emitting area of ​​the privacy sub-pixel can be reduced by narrowing the width of the first pixel opening 411, thereby reducing the power consumption and light emission angle of the privacy sub-pixel. Furthermore, by making the first light-shielding opening 421 larger, a certain amount of light can be present at a wide viewing angle in the sharing mode, thus balancing the privacy effect in the privacy mode and the display effect in the sharing mode.

[0106] In some embodiments, the display panel 2 further includes a first light-shielding layer 291, which is disposed on the side of the pixel definition layer 25a away from the substrate 21, and the first light-shielding layer 291 includes a first light-shielding opening 421 corresponding to the privacy sub-pixel 35; Wherein, the width K3 of the first light-shielding opening 421 along the second direction X is greater than the width K2 of the second pixel opening 412 along the second direction X. By making the width of the first light-shielding opening 421 along the second direction X greater than the width of the second pixel opening 412 along the second direction X, the light-emitting area of ​​the privacy sub-pixel can be reduced by decreasing the width of the first pixel opening 411, thereby reducing the power consumption and light emission angle of the privacy sub-pixel. Furthermore, by making the first light-shielding opening 421 larger, a certain amount of light can be allowed to remain at a wide viewing angle in sharing mode, thus balancing the privacy effect in privacy mode and the display effect in sharing mode.

[0107] Specifically, compared to other display devices where the width of the first light-blocking opening is smaller than the width of the first pixel opening, potentially leading to uneven brightness and significant image quality loss in sharing mode, this embodiment reduces the area of ​​the privacy sub-pixel by making the width of the first pixel opening 411 smaller than the width of the second pixel opening 412, thereby improving the privacy effect. Furthermore, making the first light-blocking opening 421 relatively large allows for some light to be present at a wide viewing angle in sharing mode, thus balancing the privacy effect in privacy mode with the display effect in sharing mode.

[0108] In some embodiments, the display panel 2 further includes a second light-shielding layer 294, which is disposed on the side of the first light-shielding layer 291 away from the substrate 21, and the second light-shielding layer 294 includes a second light-shielding opening 422 corresponding to the privacy pixel 35. Wherein, the width K4 of the second light-shielding opening 422 along the second direction X is greater than the width K2 of the second pixel opening 412 along the second direction X, and the width K4 of the second light-shielding opening 422 along the second direction X is less than the width K3 of the first light-shielding opening 421 along the second direction X.

[0109] Specifically, by making the width of the second light-shielding opening 422 along the second direction X greater than the width K2 of the second pixel opening 412 along the second direction X, the light-emitting area of ​​the privacy sub-pixel can be reduced by shrinking the width of the first pixel opening 411, thereby reducing the power consumption and light emission angle of the privacy sub-pixel. Furthermore, by making the second light-shielding opening 422 larger, a certain amount of light can be present at a wide viewing angle in the sharing mode, thus balancing the privacy effect in the privacy mode and the display effect in the sharing mode.

[0110] In some embodiments, such as Figure 15As shown, the display panel 2 further includes a second light-shielding layer 294, which is disposed on the side of the first light-shielding layer 291 away from the substrate 21. The second light-shielding layer 294 includes a second light-shielding opening 422 corresponding to the privacy pixel 35. The width K4 of the second light-shielding opening 422 along the second direction X is greater than the spacing K6 between adjacent second pixel definition portions 255a, and the width K4 of the second light-shielding opening 422 along the second direction X is less than the width K3 of the first light-shielding opening 421 along the second direction X.

[0111] Specifically, by making the width of the second light-shielding opening 422 along the second direction X greater than the spacing between adjacent second pixel definition portions 255a, the light-emitting area of ​​the privacy sub-pixel can be reduced by narrowing the width of the first pixel opening 411, thereby reducing the power consumption and light emission angle of the privacy sub-pixel. Furthermore, by making the second light-shielding opening 422 larger, a certain amount of light can be present at a wide viewing angle in the sharing mode, thus balancing the privacy effect in the privacy mode and the display effect in the sharing mode.

[0112] Specifically, compared to other display devices where the width of the second light-blocking opening is smaller than the width of the first pixel opening, potentially leading to uneven brightness and significant image quality loss in sharing mode, this embodiment reduces the area of ​​the privacy sub-pixel by making the width of the first pixel opening 411 smaller than the width of the second pixel opening 412, thereby improving the privacy effect. Furthermore, the relatively larger second light-blocking opening 422 allows for some light to be present at a wide viewing angle in sharing mode, thus balancing the privacy effect in privacy mode with the display effect in sharing mode.

[0113] Specifically, by making the width of the second light-shielding opening 422 along the second direction X smaller than the width of the first light-shielding opening 421 along the second direction X, the light emission angle of the privacy sub-pixel can be further reduced, thereby improving the privacy effect.

[0114] In some embodiments, such as Figures 5 to 11 , Figure 13As shown, the first light-shielding layer 291 further includes a third light-shielding opening 423 corresponding to the non-spy sub-pixel 34. The width K5 of the third light-shielding opening 423 along the second direction X is greater than the width K3 of the first light-shielding opening 421 along the second direction X. By making the width of the third light-shielding opening 423 along the second direction X greater than the width of the first light-shielding opening 421 along the second direction X, the light emission angle of the non-spy sub-pixel 34 can be larger, enabling wide-angle light emission in sharing mode. At the same time, by making the width of the first light-shielding opening 421 smaller, the light emission angle of the spy sub-pixel 35 can be limited, reducing the light emission angle of the spy sub-pixel 35 and enabling small-angle light emission in spy mode, thus balancing the spy-proof effect in spy mode and the wide-angle effect in sharing mode.

[0115] Specifically, such as Figure 5 As shown, the third light-blocking opening 423 can expose part of the second pixel definition section 255a, while the first light-blocking opening 421 is located between adjacent second pixel definition sections 255a, which makes the light emission angle of the privacy sub-pixel 35 smaller and the light emission angle of the non-privacy sub-pixel 34 larger, thus taking into account both the privacy effect in privacy mode and the wide viewing angle effect in sharing mode.

[0116] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the first light-shielding layer 291 also includes a third light-shielding opening 423 corresponding to the non-peeping pixel 34. The width K5 of the third light-shielding opening 423 along the second direction X is greater than or equal to the width K2 of the second pixel opening 412 along the second direction X. By making the width of the third light-shielding opening 423 along the second direction X greater than or equal to the width of the second pixel opening 412 along the second direction X, the light emission angle of the non-peeping pixel 34 is larger, which can realize a wide viewing angle light emission in the sharing mode and improve the display effect in the sharing mode.

[0117] Specifically, in the non-peeping pixel 34, making the width of the third light-blocking opening 423 greater than or equal to the width of the second pixel opening 412 can increase the angle of light emitted by the non-peeping pixel 34, thereby improving the light emission angle in the sharing mode and achieving a wide viewing angle display effect.

[0118] Specifically, from Figure 9 As can be seen, the angle range of the light emitted by the privacy pixel 35 is 174°, from Figure 10 As can be seen, the angle range of the light emitted by the non-peeping pixel 34 is b, from Figure 9 , Figure 10As can be seen, the angle range of the light emitted by the non-spy sub-pixel 34 is greater than that of the light emitted by the spy sub-pixel 35, thus achieving both the spy-proof effect in spy mode and the wide viewing angle effect in sharing mode.

[0119] In some embodiments, such as Figure 14 As shown, the second light-shielding layer 294 also includes a fourth light-shielding opening 424 corresponding to the non-peeping sub-pixel 34. The width K7 of the fourth light-shielding opening 424 along the second direction X is greater than the width K5 of the third light-shielding opening 423 along the second direction X. By making the width of the fourth light-shielding opening 424 along the second direction X greater than the width of the third light-shielding opening 423 along the second direction X, the light emission angle of the non-peeping sub-pixel 34 is larger, which can realize a wide viewing angle light emission in the sharing mode and improve the display effect in the sharing mode.

[0120] In some embodiments, such as Figure 10 As shown, the second light-shielding layer 294 can also be placed outside the non-peeping pixel 34, thereby further improving the light emission angle of the non-peeping pixel 34, enabling wide-angle light emission in sharing mode and improving the display effect in sharing mode.

[0121] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the first light-shielding layer 291 further includes a third light-shielding opening 423 corresponding to the non-privacy pixel 34. The width K5 of the third light-shielding opening 423 along the second direction X is smaller than the width N5 of the third light-shielding opening 423 along the first direction Y. By making the width of the third light-shielding opening 423 along the second direction X smaller than the width of the third light-shielding opening 423 along the first direction Y, the light emission angle of the non-privacy pixel 34 in the first direction Y can be increased, thereby improving the light emission angle of the non-privacy pixel 34 and achieving a wide viewing angle display effect.

[0122] Specifically, such as Figure 5 As shown, the third light-blocking opening 423 exposes the first pixel definition part 252a, which makes the light emission angle of the non-peeping sub-pixel 34 larger.

[0123] Specifically, when privacy protection is implemented on the display panel 2, privacy protection can be implemented on the left and right sides of the display panel 2. At this time, the width of the non-privacy sub-pixel 34 along the first direction Y can be increased, thereby increasing the light-emitting area of ​​the non-privacy sub-pixel 34. Furthermore, the width of the third light-blocking opening 423 along the second direction X is smaller than the width of the third light-blocking opening 423 along the first direction Y, resulting in a larger viewing angle of the non-privacy sub-pixel 34 in the first direction Y, thus improving the display effect in the sharing mode.

[0124] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the first light-shielding layer 291 further includes a third light-shielding opening 423 corresponding to the non-peeping sub-pixel 34. The width N5 of the third light-shielding opening 423 along the first direction Y is greater than the width N2 of the second pixel opening 412 along the first direction Y. By making the width N5 of the first direction Y greater than the width N2 of the second pixel opening 412 along the first direction Y, the light emission angle of the non-peeping sub-pixel 34 can be improved, thereby achieving a wide viewing angle display effect.

[0125] Specifically, such as Figure 5 As shown, the third light-blocking opening 423 exposes the first pixel definition part 252a, which makes the light emission angle of the non-peeping sub-pixel 34 larger.

[0126] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the width N2 of the second pixel opening 412 along the first direction Y is greater than the width K2 of the second pixel opening 412 along the second direction X. By making the width of the second pixel opening 412 along the first direction Y greater than the width of the second pixel opening 412 along the second direction X, the light-emitting area of ​​the non-peeping sub-pixel 34 can be increased, resulting in a larger viewing angle in the sharing mode and improving the display effect in the sharing mode.

[0127] Specifically, since the non-peeping pixel 34 and the peeping pixel 35 are set in the same column, it is difficult to increase the width of the non-peeping pixel 34 along the second direction X. Therefore, the area of ​​the non-peeping pixel 34 can be increased by increasing the width of the non-peeping pixel 34 along the first direction Y, thereby increasing the light-emitting area of ​​the non-peeping pixel 34, making the viewing angle larger in the sharing mode, and improving the display effect in the sharing mode.

[0128] In some embodiments, such as Figures 5 to 11 , Figure 13 As shown, the width N2 of the second pixel opening 412 along the first direction Y is greater than the width N1 of the first pixel opening 411 along the first direction Y; this makes the width of the second pixel opening 412 along the first direction Y greater than the width of the first pixel opening 411 along the first direction Y, resulting in a smaller light-emitting area of ​​the privacy sub-pixel 35, reducing the power consumption of the display panel, improving the privacy effect of the display panel, and making the light-emitting area of ​​the non-privacy sub-pixel 34 larger, resulting in a larger viewing angle in the sharing mode, and improving the display effect in the sharing mode.

[0129] In some embodiments, the width K3 of the first light-blocking opening 421 along the second direction X is equal to the width N3 of the first light-blocking opening 421 along the first direction Y, thereby making the light emission angle of the privacy sub-pixel 35 smaller in all directions, thus improving the privacy effect.

[0130] In some embodiments, the width K4 of the second light-shielding opening 422 along the second direction X is equal to the width N4 of the second light-shielding opening 422 along the first direction Y, thereby making the light emission angle of the privacy sub-pixel 35 smaller in all directions, thereby improving the privacy effect.

[0131] In some embodiments, the width N3 of the first light-blocking opening 421 in the first direction Y is smaller than the width N1 of the first pixel opening 411 along the first direction Y, thereby further reducing the light emission angle of the privacy sub-pixel and improving the privacy effect.

[0132] In some embodiments, the width N4 of the second light-shielding opening 422 along the first direction Y is smaller than the width N3 of the first light-shielding opening 421 along the first direction Y. By making the width of the second light-shielding opening 422 along the first direction Y smaller than the width of the first light-shielding opening 421 along the first direction Y, the light emission angle of the privacy sub-pixel can be further reduced, thereby improving the privacy effect.

[0133] In some embodiments, the spacing K6 between adjacent second pixel definition portions 255a is equal to the width K2 of the second pixel opening 412 along the second direction X.

[0134] Specifically, such as Figure 5 , Figure 6 As shown, the structure of the first pixel definition layer 252 and the second pixel definition layer 255 can be seen, as follows: Figure 5 , Figure 6 As shown in (a), the first pixel definition layer 252 includes multiple first pixel definition portions 252a and multiple extension portions 252b. The extension portions 252b are connected to the first pixel definition portions 252a to form a first pixel opening 411.
