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 in various fields due to their lightweight, wide viewing angle, low power consumption, fast response speed, low temperature resistance, high luminous efficiency, and the ability to fabricate flexible displays. To achieve privacy features, existing OLED displays employ different technologies. For example, a privacy film is attached to the display device, but this results in the inability to switch between privacy and shared states. Alternatively, a privacy structure is placed on the light-emitting surface of the display device to adjust between privacy and shared states. However, this privacy structure is often formed using liquid crystal structures, resulting in a relatively large thickness and consequently, a larger display device thickness.

[0003] Therefore, the existing OLED display devices that use a privacy shield structure to switch between privacy and shared states have a significant thickness issue. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the technical problem of large thickness in existing OLED display devices that use a privacy structure to switch between privacy mode and shared mode.

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, the display panel comprising: Substrate; A pixel definition layer is disposed on one side of the substrate. The pixel definition layer includes a plurality of first pixel definition portions and a plurality of second pixel definition portions. The first pixel definition portions have first pixel openings, and the second pixel definition portions have second pixel openings. The light-emitting material layer includes a first type of light-emitting part and a second type of light-emitting part. The first type of light-emitting part is disposed in the first pixel opening, and the second type of light-emitting part is disposed at least in the second pixel opening. The area of ​​the first type of light-emitting part is smaller than the area of ​​the second type of light-emitting part. A black matrix layer is disposed on the side of the pixel definition layer away from the substrate. The black matrix layer includes a first light-shielding part and a second light-shielding part. The first light-shielding part has a first light-filtering opening, and the second light-shielding part has a second light-filtering opening. A color resist layer includes a first type of color resist portion and a second type of color resist portion. The first type of color resist portion is disposed within the first light filter opening, and the second type of color resist portion is disposed at least within the second light filter opening. The first type of color resist portion is disposed corresponding to the first type of light emitting portion, and the second type of color resist portion is disposed corresponding to the second type of light emitting portion. The area of ​​the first type of color resist portion is smaller than the area of ​​the second type of color resist portion. Wherein, the distance between the upper surface of the second pixel definition part and the substrate is smaller than the distance between the upper surface of the second type of light-emitting part and the substrate; And / or, the distance between the upper surface of the second light-shielding portion and the substrate is less than the distance between the upper surface of the second type of color resist portion and the substrate.

[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. By making the area of ​​the first type of light-emitting part smaller than the area of ​​the second type of light-emitting part, the display panel can switch between a privacy mode and a shared mode by using different light-emitting parts to emit light in different display modes, eliminating the need for a privacy structure and reducing the thickness of the display panel. Furthermore, by making the distance between the upper surface of the second pixel defining part and the substrate smaller than the distance between the upper surface of the second type of light-emitting part and the substrate, and / or making the distance between the upper surface of the second light-shielding part and the substrate smaller than the distance between the upper surface of the second type of color resist part and the substrate, the viewing angle of the privacy mode and / or the shared mode can be further adjusted, thereby improving the display effect.

[0008] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0009] To gain a more complete understanding of this application and its beneficial effects, the following description will be provided in conjunction with the accompanying drawings, wherein the same reference numerals in the following description denote the same parts.

[0010] Figure 1 This is a schematic diagram of a comparison display device provided in an embodiment of this application.

[0011] Figure 2 This is a first schematic diagram of a display panel provided in an embodiment of this application.

[0012] Figure 3 This is a second schematic diagram of a display panel provided in an embodiment of this application. Detailed Implementation

[0013] 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.

[0014] To illustrate the principle behind the technical problems in the embodiments of this application, some comparative display devices are provided in the embodiments of this application. It should be understood that these comparative display devices should not be regarded as prior art in the embodiments of this application. Figure 1 As shown, in order to switch between privacy mode and sharing mode without reducing pixel resolution, the comparison display device splits the sub-pixels into privacy sub-pixels 101 and regular sub-pixels 102. The area of ​​regular sub-pixels 102 is larger than that of privacy sub-pixels 101. Regular sub-pixels 102 can emit a second light 152 at a large angle, while privacy sub-pixels 101 can emit a first light 151 at a small angle. Thus, the circuit can control the regular sub-pixels 102 and privacy sub-pixels 101 to selectively turn on and light up, thereby achieving the switching between privacy mode and sharing mode.

[0015] But from Figure 1 As can be seen, in the regular sub-pixel 102 and the privacy sub-pixel 101, the thickness of the barrier 11 is the same as that of the first light-emitting material 121 and the second light-emitting material 122, or the upper surface of the barrier 11 is located on the same plane or substantially on the same plane as the upper surfaces of the first light-emitting material 121 and the second light-emitting material 122. The thickness of the black matrix 13 is the same as that of the first light-filtering material 141 and the second light-filtering material 142, or the upper surface of the black matrix 13 is located on the same plane as the upper surfaces of the first light-filtering material 141 and the second light-filtering material 142, or the substrate is located on the same plane. This means that when adjusting the viewing angle difference between the privacy state and the regular state, it can only be controlled by the area of ​​the regular sub-pixel 102 and the privacy sub-pixel 101. The margin is small, making it difficult to meet the effects of the privacy state and the regular state, resulting in poor display effect.

[0016] Other comparative display devices incorporate a privacy screen on one side of the display panel to adjust between privacy and shared states. However, these privacy screens are often formed using liquid crystal structures, resulting in significant thickness and consequently, a large overall thickness of the display device. Therefore, existing OLED display devices using privacy screens for switching between privacy and shared states suffer from the technical challenge of excessive thickness. Furthermore, controlling the privacy and shared states through area adjustment presents significant difficulties and results in poor display quality.

[0017] This application provides a display panel and a display device to address the aforementioned technical problems.

[0018] like Figure 2 , Figure 3 As shown in the figure, this application embodiment provides a display panel 2, which includes a first type of sub-pixels 201 and a second type of sub-pixels 202. The first type of sub-pixels 201 includes a first type of first sub-pixel, a first type of second sub-pixel, and a first type of third sub-pixel with different emission colors. The second type of sub-pixels 202 includes a second type of first sub-pixel, a second type of second sub-pixel, and a third type of sub-pixel with different emission colors. The emission colors of the first type of first sub-pixel, the first type of second sub-pixel, and the first type of third sub-pixel are the same as the emission colors of the second type of first sub-pixel, the second type of second sub-pixel, and the third type of sub-pixel, respectively. The areas of the first type of first sub-pixel, the first type of second sub-pixel, and the first type of third sub-pixel are smaller than the areas of the second type of first sub-pixel, the second type of second sub-pixel, and the third type of sub-pixel, respectively.

[0019] Specifically, the widths of the first type first sub-pixel, the first type second sub-pixel, and the first type third sub-pixel can be smaller than the widths of the second type first sub-pixel, the second type second sub-pixel, and the second type third sub-pixel, respectively; or the lengths of the first type first sub-pixel, the first type second sub-pixel, and the first type third sub-pixel can be smaller than the lengths of the second type first sub-pixel, the second type second sub-pixel, and the second type third sub-pixel, respectively; or the widths of the first type first sub-pixel, the first type second sub-pixel, and the first type third sub-pixel can be smaller than the widths of the second type first sub-pixel, the second type second sub-pixel, and the second type third sub-pixel, respectively, and the lengths of the first type first sub-pixel, the first type second sub-pixel, and the first type third sub-pixel can be smaller than the lengths of the second type first sub-pixel, the second type second sub-pixel, and the second type third sub-pixel, respectively.

[0020] like Figure 2 , Figure 3As shown, this application embodiment provides a display panel 2, which includes a substrate 21, a pixel definition layer 24, and a light-emitting material layer 25. The pixel definition layer 24 is disposed on one side of the substrate 21 and includes a plurality of first pixel definition portions 241, a plurality of second pixel definition portions 242, a plurality of first pixel openings 331, and a plurality of second pixel openings 332. The first pixel definition portions 241 are disposed around the first pixel openings 331, and the second pixel definition portions 242 are disposed around the second pixel openings 332. The light-emitting material layer 25 includes a first type of light-emitting portion 251 and a second type of light-emitting portion 252. The first type of light-emitting portion 251 is disposed within the first pixel opening 331, and the second type of light-emitting portion 252 is disposed within the second pixel opening 332. The first type of light-emitting part 251 includes a first type of first light-emitting part 251a, a first type of second light-emitting part 251b and a first type of third light-emitting part 251c respectively corresponding to a first type of first sub-pixel, a first type of second sub-pixel and a first type of third sub-pixel; The distance between the upper surface of the first pixel definition portion 241 surrounding the first type of first light-emitting portion 251a and the substrate is greater than the distance between the upper surface of the first type of first light-emitting portion 251a and the substrate; and / or, the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of second light-emitting portion 251b and the substrate is greater than the distance between the upper surface of the first type of second light-emitting portion 251b and the substrate; and / or, the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of third light-emitting portion 251c and the substrate is greater than the distance between the upper surface of the first type of third light-emitting portion 251c and the substrate.

[0021] Specifically, by making the distance between the upper surface of the first pixel defining part surrounding each first type of light-emitting part and the substrate greater than the distance between the upper surface of each first type of light-emitting part and the substrate, the light emission angle can be controlled by the first pixel defining part, thereby reducing the light emission angle of the first type of light-emitting part and thus achieving a better privacy protection effect.

[0022] Specifically, it is understandable that, due to the different light-emitting materials of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c, and the different luminous efficiencies of each light-emitting material, some display panels will have different light-emitting areas for at least two of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c; other display panels will have different thicknesses for the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c; and still other display panels will have different light-emitting surfaces for at least two of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c. Since the areas of the first light-emitting parts 251a, 251b, and 251c are different, and their thicknesses are also different, the distances between the upper surfaces of the first light-emitting parts 251a, 251b, and 251c and the substrate are also different. Therefore, it is necessary to set the distances between the upper surfaces of the first pixel definition portion 241 surrounding the first light-emitting part 251a, the first pixel definition portion 241 surrounding the first light-emitting part 251b, and the first pixel definition portion 241 surrounding the first light-emitting part 251c, and the substrate accordingly, so as to achieve similar or even identical viewing angles for each light-emitting part.

[0023] Specifically, the difference between the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of first light-emitting portion 251a and the substrate and the distance between the upper surface of the first type of first light-emitting portion 251a and the substrate can be equal to the difference between the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of second light-emitting portion 251b and the substrate and the distance between the upper surface of the first type of second light-emitting portion 251b and the substrate; the difference between the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of second light-emitting portion 251b and the substrate and the distance between the upper surface of the first type of second light-emitting portion 251b and the substrate can be equal to the difference between the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of third light-emitting portion 251c and the substrate and the distance between the upper surface of the first type of third light-emitting portion 251c and the substrate. However, the embodiments of this application are not limited to this. For example, the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of first light-emitting portion 251a and the substrate can be equal to the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of second light-emitting portion 251b and the substrate, and the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of first light-emitting portion 251a and the substrate can be equal to the distance between the upper surface of the first pixel definition portion 241 surrounding the first type of third light-emitting portion 251c and the substrate.

[0024] like Figure 2 , Figure 3 As shown, this application embodiment provides a display panel 2, which includes a substrate 21, a pixel definition layer 24, and a light-emitting material layer 25. The pixel definition layer 24 is disposed on one side of the substrate 21 and includes a plurality of first pixel definition portions 241, a plurality of second pixel definition portions 242, a plurality of first pixel openings 331, and a plurality of second pixel openings 332. The first pixel definition portions 241 are disposed around the first pixel openings 331, and the second pixel definition portions 242 are disposed around the second pixel openings 332. The light-emitting material layer 25 includes a first type of light-emitting portion 251 and a second type of light-emitting portion 252. The first type of light-emitting portion 251 is disposed within the first pixel opening 331, and the second type of light-emitting portion 252 is disposed within the second pixel opening 332. The second type of light-emitting part 252 includes a second type of first light-emitting part 252a, a second type of second light-emitting part 252b, and a third type of light-emitting part 252c, which respectively correspond to the second type of first sub-pixel, the second type of second sub-pixel, and the third type of third sub-pixel; The distance between the upper surface of the second pixel defining portion 242 surrounding the second type first light-emitting portion 252a and the substrate is smaller than the distance between the upper surface of the second type first light-emitting portion 252a and the substrate; and / or, the distance between the upper surface of the second pixel defining portion 242 surrounding the second type second light-emitting portion 252b and the substrate is smaller than the distance between the upper surface of the second type second light-emitting portion 252b and the substrate; and / or, the distance between the upper surface of the second pixel defining portion 242 surrounding the second type third light-emitting portion 252c and the substrate is smaller than the distance between the upper surface of the second type third light-emitting portion 252c and the substrate.

[0025] Specifically, by making the distance between the upper surface of the second pixel definition section 242 surrounding each second type of light-emitting part and the substrate smaller than the distance between the upper surface of each second type of light-emitting part and the substrate, the light emission angle can be controlled by the second pixel definition section 242, thereby increasing the light emission angle of the second type of light-emitting part and thus better realizing a wide viewing angle display in normal display mode.

[0026] Specifically, it is understandable that, due to the different light-emitting materials of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c, and the different luminous efficiencies of each light-emitting material, some display panels will have different light-emitting areas for at least two of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c; other display panels will have different thicknesses for the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c; and still other display panels will have different luminous efficiencies for at least two of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c. The light areas are different, and the thicknesses of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c are different, resulting in different distances between the upper surfaces of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c and the substrate. Therefore, it is necessary to set the distances between the upper surfaces of the second pixel definition part 242 surrounding the second type first light-emitting part 252a, the second pixel definition part 242 surrounding the second type second light-emitting part 252b, and the second pixel definition part 242 surrounding the second type third light-emitting part 252c, so as to achieve similar or even the same viewing angles for each light-emitting part.

[0027] Specifically, the difference between the distance between the upper surface of the second pixel definition portion 242 surrounding the second type of first light-emitting portion 252a and the substrate and the distance between the upper surface of the second type of first light-emitting portion 252a and the substrate can be equal to the difference between the distance between the upper surface of the second pixel definition portion 242 surrounding the second type of second light-emitting portion 252b and the substrate and the distance between the upper surface of the second type of second light-emitting portion 252b and the substrate; the difference between the distance between the upper surface of the second pixel definition portion 242 surrounding the second type of second light-emitting portion 252b and the substrate and the distance between the upper surface of the second type of second light-emitting portion 252b and the substrate can be equal to the difference between the distance between the upper surface of the second pixel definition portion 242 surrounding the second type of third light-emitting portion 252c and the substrate and the distance between the upper surface of the third type of light-emitting portion 252c and the substrate. However, the embodiments of this application are not limited to this. For example, the distance between the upper surface of the second pixel definition portion 242 surrounding the second type first light-emitting portion 252a and the substrate can be equal to the distance between the upper surface of the second pixel definition portion 242 surrounding the second type second light-emitting portion 252b and the substrate, and the distance between the upper surface of the second pixel definition portion 242 surrounding the second type first light-emitting portion 252a and the substrate can be equal to the distance between the upper surface of the second pixel definition portion 242 surrounding the second type third light-emitting portion 252c and the substrate.

[0028] Specifically, some of the above embodiments are illustrated by taking the different thicknesses of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c as examples. However, the embodiments of this application are not limited to this. The thicknesses of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c can be the same. The following embodiments are illustrated by taking the same thickness of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c as examples. For cases where the thicknesses of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c are different, corresponding designs can be made.

[0029] Specifically, some of the above embodiments are illustrated by taking the different thicknesses of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c as examples. However, the embodiments of this application are not limited to this. The thicknesses of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c can be the same. The following embodiments are illustrated by taking the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c as examples. For cases where the thicknesses of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c are different, corresponding designs can be made.

[0030] like Figure 2 , Figure 3As shown, this application embodiment provides a display panel 2, which includes a substrate 21, a pixel definition layer 24, a light-emitting material layer 25, a black matrix layer 29, and a color resist layer 31. The pixel definition layer 24 is disposed on one side of the substrate 21 and includes a plurality of first pixel definition portions 241 and a plurality of second pixel definition portions 242. The first pixel definition portions 241 have first pixel openings 331, and the second pixel definition portions 242 have second pixel openings 332. The light-emitting material layer 25 includes first type light-emitting portions 251 and second type light-emitting portions 252. The first type light-emitting portions 251 are disposed within the first pixel openings 331, and the second type light-emitting portions 252 are at least disposed within the second pixel openings 332. The black matrix layer 29... Layer 29 is disposed on the side of the pixel definition layer 24 away from the substrate 21. The black matrix layer 29 includes a first light-shielding part 291 and a second light-shielding part 292. The first light-shielding part 291 has a first light-filtering opening 341, and the second light-shielding part 292 has a second light-filtering opening 342. The color resist layer 31 includes a first type of color resist 311 and a second type of color resist 312. The first type of color resist 311 is disposed at least in the first light-filtering opening 341, and the second type of color resist 312 is disposed in the second light-filtering opening 342. The first type of color resist 311 is disposed corresponding to the first type of light-emitting part 251, and the second type of color resist 312 is disposed corresponding to the second type of light-emitting part 252. The area of ​​the first type of color resist 311 is smaller than the area of ​​the second type of color resist 312. The first type of color resist 311 includes a first type of first color resist 311a, a first type of second color resist 311b, and a first type of third color resist 311c, which respectively correspond to a first type of first sub-pixel, a first type of second sub-pixel, and a first type of third sub-pixel. The distance between the upper surface of the first light-shielding portion 291 surrounding the first type of first color resist portion 311a and the substrate is greater than the distance between the upper surface of the first type of first color resist portion 311a and the substrate; and / or, the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of second color resist portion 311b and the substrate is greater than the distance between the upper surface of the first type of second color resist portion 311b and the substrate; and / or, the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of third color resist portion 311c and the substrate is greater than the distance between the upper surface of the first type of third color resist portion 311c and the substrate.

[0031] Specifically, by making the distance between the upper surface of the first light-shielding part surrounding each first type of color resist part and the substrate greater than the distance between the upper surface of each first type of color resist part and the substrate, the light emission angle can be controlled by the first light-shielding part, thereby reducing the light emission angle of the first type of light-emitting part and thus achieving a better privacy protection effect.

[0032] Specifically, it is understandable that, due to the different light-emitting materials of the first type of first light-emitting portion 251a, the first type of second light-emitting portion 251b, and the first type of third light-emitting portion 251c, and the different luminous efficiencies of each light-emitting material, some display panels will have at least two different areas of the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c; other display panels will have different thicknesses of the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c; and still some display panels will have at least one different area of ​​the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c. The two types of light-emitting parts have different areas, and the thicknesses of the first type of first color resist 311a, the first type of second color resist 311b, and the first type of third color resist 311c are different, resulting in different distances between the upper surfaces of the first type of first color resist 311a, the first type of second color resist 311b, and the first type of third color resist 311c and the substrate. Therefore, it is necessary to set the distances between the upper surfaces of the first light-shielding part 291 surrounding the first type of first color resist 311a, the first light-shielding part 291 surrounding the first type of second color resist 311b, and the first light-shielding part 291 surrounding the first type of third color resist 311c, so as to achieve similar or even the same viewing angles for each light-emitting part.

[0033] Specifically, the difference between the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of first color resist portion 311a and the substrate and the distance between the upper surface of the first type of first color resist portion 311a and the substrate can be equal to the difference between the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of second color resist portion 311b and the substrate and the distance between the upper surface of the first type of second color resist portion 311b and the substrate; the difference between the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of second color resist portion 311b and the substrate and the distance between the upper surface of the first type of second color resist portion 311b and the substrate can be equal to the difference between the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of third color resist portion 311c and the substrate and the distance between the upper surface of the first type of third color resist portion 311c and the substrate. However, the embodiments of this application are not limited to this. For example, the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of first color resist portion 311a and the substrate can be equal to the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of second color resist portion 311b and the substrate, and the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of first color resist portion 311a and the substrate can be equal to the distance between the upper surface of the first light-shielding portion 291 surrounding the first type of third color resist portion 311c and the substrate.

[0034] like Figure 2 , Figure 3As shown, this application embodiment provides a display panel 2, which includes a substrate 21, a pixel definition layer 24, a light-emitting material layer 25, a black matrix layer 29, and a color resist layer 31. The pixel definition layer 24 is disposed on one side of the substrate 21 and includes a plurality of first pixel definition portions 241, a plurality of second pixel definition portions 242, a plurality of first pixel openings 331, and a plurality of second pixel openings 332. The first pixel definition portions 241 are disposed around the first pixel openings 331, and the second pixel definition portions 242 are disposed around the second pixel openings 332. The light-emitting material layer 25 includes a first type of light-emitting portion 251 and a second type of light-emitting portion 252. The first type of light-emitting portion 251 is disposed within the first pixel opening 331, and the second type of light-emitting portion 252 is disposed within the second pixel opening 332. A matrix layer 29 is disposed on the side of the pixel definition layer 24 away from the substrate 21. The black matrix layer 29 includes a first light-shielding part 291, a second light-shielding part 292, a first light-filtering opening 341, and a second light-filtering opening 342. The first light-shielding part 291 is disposed around the first light-filtering opening 341, and the second light-shielding part 292 is disposed around the second light-filtering opening 342. The color resist layer 31 includes a first type of color resist 311 and a second type of color resist 312. The first type of color resist 311 is disposed within the first light-filtering opening 341, and the second type of color resist 312 is disposed within the second light-filtering opening 342. The first type of color resist 311 is disposed corresponding to the first type of light-emitting part 251, and the second type of color resist 312 is disposed corresponding to the second type of light-emitting part 252. The area of ​​the first type of color resist 311 is smaller than the area of ​​the second type of color resist 312. The second type of color resist 312 includes a second type of first color resist 312a, a second type of second color resist 312b, and a third type of color resist 312c, which respectively correspond to the first type of first sub-pixel, the first type of second sub-pixel, and the first type of third sub-pixel. The distance between the upper surface of the second light-shielding portion 292 surrounding the second type of first color resist portion 312a and the substrate is smaller than the distance between the upper surface of the second type of first color resist portion 312a and the substrate; and / or, the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of second color resist portion 312b and the substrate is smaller than the distance between the upper surface of the second type of second color resist portion 312b and the substrate; and / or, the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of third color resist portion 312c and the substrate is smaller than the distance between the upper surface of the second type of third color resist portion 312c and the substrate.

[0035] Specifically, by making the distance between the upper surface of the second light-shielding part surrounding each second type of color resist part and the substrate greater than the distance between the upper surface of each second type of color resist part and the substrate, the light emission angle can be controlled by the second light-shielding part, thereby increasing the light emission angle of the second type of light-emitting part and thus achieving a better normal display effect.

[0036] Specifically, it is understandable that, due to the different light-emitting materials of the second type first light-emitting part 252a, the second type second light-emitting part 252b, and the third type third light-emitting part 252c, and the different luminous efficiencies of each light-emitting material, some display panels will have at least two of the second type first color resist part 312a, the second type second color resist part 312b, and the third type third color resist part 312c having different areas; other display panels will have different thicknesses of the second type first color resist part 312a, the second type second color resist part 312b, and the third type third color resist part 312c; and still other display panels will have at least one of the second type first color resist part 312a, the second type second color resist part 312b, and the third type third color resist part 312c having different thicknesses. The two types of light-emitting parts have different areas, and the thicknesses of the second type of first color resist 312a, the second type of second color resist 312b, and the third type of color resist 312c are different. This results in different distances between the upper surfaces of the second type of first color resist 312a, the second type of second color resist 312b, and the third type of color resist 312c and the substrate. Therefore, it is necessary to set the distances between the upper surfaces of the second light-shielding part 292 surrounding the second type of first color resist 312a, the second light-shielding part 292 surrounding the second type of second color resist 312b, and the second light-shielding part 292 surrounding the second type of third color resist 312c and the substrate, so as to achieve similar or even the same viewing angles for each light-emitting part.

[0037] Specifically, the difference between the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of first color resist portion 312a and the substrate and the distance between the upper surface of the second type of first color resist portion 312a and the substrate can be equal to the difference between the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of second color resist portion 312b and the substrate and the distance between the upper surface of the second type of second color resist portion 312b and the substrate; the difference between the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of second color resist portion 312b and the substrate and the distance between the upper surface of the second type of second color resist portion 312b and the substrate can be equal to the difference between the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of third color resist portion 312c and the substrate and the distance between the upper surface of the second type of third color resist portion 312c and the substrate. However, the embodiments of this application are not limited to this. For example, the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of first color resist portion 312a and the substrate can be equal to the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of second color resist portion 312b and the substrate, and the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of first color resist portion 312a and the substrate can be equal to the distance between the upper surface of the second light-shielding portion 292 surrounding the second type of third color resist portion 312c and the substrate.

[0038] Specifically, some of the above embodiments are illustrated by taking the different thicknesses of the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c as examples. However, the embodiments of this application are not limited to this. The thicknesses of the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c can be the same. The following embodiments are illustrated by taking the same thickness of the first type of first color resist portion 311a, the first type of second color resist portion 311b, and the first type of third color resist portion 311c as examples.

[0048] Specifically, the light emission colors of the first type of first light-emitting part 251a, the first type of second light-emitting part 251b, and the first type of third light-emitting part 251c can be red, green, and blue, respectively. However, the embodiments of this application are not limited to this.

[0049] like Figure 2 , Figure 3As shown in the figure, this application embodiment provides a display panel 2, which includes a substrate 21, a pixel definition layer 24, a light-emitting material layer 25, a black matrix layer 29, and a color resist layer 31. The pixel definition layer 24 is disposed on one side of the substrate 21 and includes a plurality of first pixel definition portions 241 and a plurality of second pixel definition portions 242. The first pixel definition portions 241 have first pixel openings 331, and the second pixel definition portions 242 have second pixel openings 332. The light-emitting material layer 25 includes a first type of light-emitting portion 251 and a second type of light-emitting portion 252. The first type of light-emitting portion 251 is disposed within the first pixel opening 331, and the second type of light-emitting portion 252 is at least disposed within the second pixel opening 332. The area of ​​the first type of light-emitting portion 251 is smaller than that of the second type of light-emitting portion 252. The area of ​​the light-emitting portion 252; the black matrix layer 29 is disposed on the side of the pixel definition layer 24 away from the substrate 21, the black matrix layer 29 includes a first light-shielding portion 291 and a second light-shielding portion 292, the first light-shielding portion 291 has a first light-filtering opening 341, and the second light-shielding portion 292 has a second light-filtering opening 342; the color resist layer 31 includes a first type of color resist 311 and a second type of color resist 312, the first type of color resist 311 is at least disposed in the first light-filtering opening 341, the second type of color resist 312 is disposed in the second light-filtering opening 342, the first type of color resist 311 is correspondingly disposed with the first type of light-emitting portion 251, the second type of color resist 312 is correspondingly disposed with the second type of light-emitting portion 252, and the area of ​​the first type of color resist 311 is smaller than the area of ​​the second type of color resist 312; Wherein, the distance H2 between the upper surface of the second pixel definition part 242 and the substrate 21 is smaller than the distance H3 between the upper surface of the second type of light-emitting part 252 and the substrate 21; And / or, the distance H6 between the upper surface of the second light-shielding part 292 and the substrate 21 is smaller than the distance H7 between the upper surface of the second type of color resist part 312 and the substrate 21.

[0050] This application provides a display panel 2. By making the area of ​​the first type of light-emitting part 251 smaller than the area of ​​the second type of light-emitting part 252, the display panel 2 can switch between a privacy mode and a shared mode by using different light-emitting parts to emit light in different display modes, eliminating the need for a privacy structure and reducing the thickness of the display panel 2. Furthermore, by making the distance between the upper surface of the second pixel definition part 242 and the substrate 21 smaller than the distance between the upper surface of the second type of light-emitting part 252 and the substrate 21, and / or making the distance between the upper surface of the second light-shielding part 292 and the substrate 21 smaller than the distance between the upper surface of the second type of color resist part 312 and the substrate 21, the viewing angle of the privacy mode and / or the shared mode can be further adjusted, thereby improving the display effect.

[0051] In some embodiments, the distance H4 between the upper surface of the first pixel definition portion 241 and the substrate 21 is greater than the distance H1 between the upper surface of the first type of light-emitting portion 251 and the substrate 21, which can further adjust the viewing angle in the privacy mode and / or shared mode, thereby improving the display effect.

[0052] In some embodiments, the distance H8 between the upper surface of the first light-shielding portion 291 and the substrate 21 is greater than the distance H5 between the upper surface of the first color resist portion 311 and the substrate 21; the viewing angle in the privacy mode and / or shared mode can be further adjusted, thereby improving the display effect.

[0053] Specifically, by making the distance between the upper surface of the first pixel definition part 241 and the substrate 21 greater than the distance between the upper surface of the first type of light-emitting part 251 and the substrate 21, the angle of the third light ray 321 emitted by the first type of light-emitting part 251 can be controlled, the light emission angle of the light emitted by the first type of light-emitting part 251 can be reduced, the privacy protection effect can be further improved, and the privacy protection effect can be more easily controlled.

[0054] Specifically, by making the distance between the upper surface of the second pixel definition part 242 and the substrate 21 smaller than the distance between the upper surface of the second type of light-emitting part 252 and the substrate 21, the angle of the fourth light ray 322 emitted by the second type of light-emitting part 252 can be controlled, the light emission angle of the light emitted by the second type of light-emitting part 252 can be expanded, the normal display effect can be further improved, and the viewing angle during normal display can be controlled more easily.

[0055] Specifically, by making the distance between the upper surface of the first light-shielding part 291 and the substrate 21 greater than the distance between the upper surface of the first type of color resist part 311 and the substrate 21, the angle of the third light ray 321 emitted by the first type of light-emitting part 251 can be controlled, the light emission angle of the light emitted by the first type of light-emitting part 251 can be reduced, the privacy protection effect can be further improved, and the privacy protection effect can be more easily controlled.

[0056] Specifically, by making the distance between the upper surface of the second light-shielding part 292 and the substrate 21 smaller than the distance between the upper surface of the second type of color resist part 312 and the substrate 21, the angle of the fourth light ray 322 emitted by the second type of light-emitting part 252 can be controlled, the light emission angle of the light emitted by the second type of light-emitting part 252 can be expanded, the normal display effect can be further improved, and the viewing angle during normal display can be controlled more easily.

[0057] In some embodiments, such as Figure 2 , Figure 3As shown, the thickness L2 of the first pixel defining part 241 is greater than the thickness L1 of the second pixel defining part 242. By making the thickness of the first pixel defining part 241 greater than the thickness of the second pixel defining part 242, the distance between the upper surface of the first pixel defining part 241 and the substrate 21 can be greater than the distance between the upper surface of the first type of light-emitting part 251 and the substrate 21; and / or, the distance between the upper surface of the second pixel defining part 242 and the substrate 21 is less than the distance between the upper surface of the second type of light-emitting part 252 and the substrate 21, thereby controlling the angle of the light emitted by the first type of light-emitting part 251 and / or the second type of light-emitting part 252, further improving the privacy protection effect and / or further improving the normal display effect, and improving the display effect of the display panel.

[0058] Specifically, it is understood that the pixel definition layer 24 is disposed on the pixel electrode layer 23. Therefore, the thickness of the portion of the pixel definition layer 24 located on the pixel electrode layer 23 and the portion of the pixel definition layer 24 located on the driving circuit layer 22 may be different. In this embodiment, the thickness of each pixel definition portion is determined based on the surface of the pixel definition layer 24 closest to the substrate 21. However, this embodiment is not limited to this. The thickness of each pixel definition portion can be determined based on the lower surface of the portion of the pixel definition layer 24 located on the pixel definition layer.

[0059] In some embodiments, such as Figure 2 , Figure 3 As shown, the thickness L3 of the first type of light-emitting part 251 is less than the thickness L4 of the second type of light-emitting part 252, and the second type of light-emitting part 252 extends from the second pixel opening to at least the upper surface of the second pixel defining part 242. By making the thickness of the first type of light-emitting part 251 less than the thickness of the second type of light-emitting part 252, the distance between the upper surface of the first pixel defining part 241 and the substrate 21 can be greater than the distance between the upper surface of the first type of light-emitting part 251 and the substrate 21; and / or, the distance between the upper surface of the second pixel defining part 242 and the substrate 21 is less than the distance between the upper surface of the second type of light-emitting part 252 and the substrate 21, thereby controlling the angle of the light emitted by the first type of light-emitting part 251 and / or the second type of light-emitting part 252, further improving the privacy protection effect and / or further improving the normal display effect, and improving the display effect of the display panel. Furthermore, by making the second type of light-emitting part 252 extend from the second pixel opening to the upper surface of the second pixel defining part 242, the viewing angle of the second type of light-emitting part 252 can be further increased, improving the normal display effect.

[0060] Specifically, when the second type of light-emitting portion 252 extends from the second pixel opening to the upper surface of the second pixel defining portion 242, the widths of the portions of the second type first sub-pixel, the second type second sub-pixel, and the third type third sub-pixel extending to the upper surface of the second pixel defining portion 242 can be different, thereby improving color shift. For example, if the display panel has a greenish tint at wide viewing angles, and assuming the light-emitting colors of the second type first sub-pixel, the second type second sub-pixel, and the third type third sub-pixel are red, green, and blue respectively, then the width of the portion of the second type second sub-pixel extending to the upper surface of the second pixel defining portion 242 can be smaller than the width of the portion of the second type first sub-pixel extending to the upper surface of the second pixel defining portion 242, and the width of the portion of the second type second sub-pixel extending to the upper surface of the second pixel defining portion 242 is smaller than the width of the portion of the second type third sub-pixel extending to the upper surface of the second pixel defining portion 242. However, the embodiments of this application are not limited to this; the widths of the portions of the second type first sub-pixel, the second type second sub-pixel, and the third type third sub-pixel extending to the upper surface of the second pixel defining portion 242 can be the same.

[0061] In some embodiments, such as Figure 2 , Figure 3 As shown, the thickness of the second type of light-emitting part 252 is less than the thickness of the first pixel defining part 241. By making the thickness of the second type of light-emitting part 252 less than the thickness of the first pixel defining part 241, the first pixel defining part 241 can block the second type of light-emitting part 252, preventing the second type of light-emitting part 252 from flowing into the area where the first type of light-emitting part 251 is located. This results in the thickness of the first type of light-emitting part 251 and the second type of light-emitting part 252 becoming uncontrollable, making it easier to control the privacy protection effect and normal display effect of the display panel.

[0062] Specifically, the distance between the upper surface of the first type of light-emitting part 251 and the substrate can be equal to the distance between the upper surface of the second pixel defining part and the substrate.

[0063] Specifically, when the bottom surfaces of the light-emitting part and the pixel definition part are on the same plane, the thickness of the first type of light-emitting part 251 can be equal to the thickness of the second pixel definition part, the thickness of the second pixel definition part is less than the thickness of the second type of light-emitting part, and the thickness of the second type of light-emitting part is less than the thickness of the first pixel definition part.

[0064] In some embodiments, such as Figure 2 , Figure 3As shown, the thickness L6 of the first light-shielding part 291 is greater than the thickness L5 of the second light-shielding part 292. By making the thickness L6 of the first light-shielding part 291 greater than the thickness L5 of the second light-shielding part 292, the distance between the upper surface of the first light-shielding part 291 and the substrate 21 is greater than the distance between the upper surface of the first type of color resist part 311 and the substrate 21; and / or, the distance between the upper surface of the second light-shielding part 292 and the substrate 21 is less than the distance between the upper surface of the second type of color resist part 312 and the substrate 21, the viewing angle in the privacy mode and / or shared mode can be further adjusted, thereby improving the display effect.

[0065] In some embodiments, such as Figure 2 , Figure 3 As shown, the thickness L7 of the first type of color resist 311 is less than the thickness L8 of the second type of color resist 312, and the second type of color resist 312 extends from the second light-filtering opening to at least the upper surface of the second light-shielding part 292. By making the thickness of the first type of color resist 311 less than the thickness of the second type of color resist 312, the distance between the upper surface of the first light-shielding part 291 and the substrate 21 can be greater than the distance between the upper surface of the first type of color resist 311 and the substrate 21; and / or, the distance between the upper surface of the second light-shielding part 292 and the substrate 21 is less than the distance between the upper surface of the second type of color resist 312 and the substrate 21, thereby controlling the angle of the light emitted by the first type of light-emitting part 251 and / or the second type of light-emitting part 252, further improving the privacy protection effect and / or further improving the normal display effect, and improving the display effect of the display panel. Furthermore, by extending the second type of color resist portion 312 from inside the second light filter opening to the upper surface of the second light-shielding portion 292, the viewing angle of the second type of light-emitting portion 252 can be further increased, thereby improving the normal display effect.

[0066] Specifically, when the second type of color resist portion 312 extends from the second light-filtering opening to the upper surface of the second light-shielding portion 292, the widths of the portions of the second type of first color resist portion 312a, the second type of second color resist portion 312b, and the third type of color resist portion 312c extending to the upper surface of the second light-shielding portion 292 can be different, thereby improving color shift. For example, if the display panel has a greenish tint at wide viewing angles, the widths of the portions of the second type of first color resist portion 312a, the second type of second color resist portion 312b, and the third type of color resist portion 312c extending to the upper surface of the second light-shielding portion 292 can be different, thereby improving color shift. Taking the light-transmitting colors of part 312c as red, green, and blue, the width of the portion of the second type of second color resist 312b extending to the upper surface of the second light-shielding part 292 can be smaller than the width of the portion of the second type of first color resist 312a extending to the upper surface of the second light-shielding part 292, and the width of the portion of the second type of second color resist 312b extending to the upper surface of the second light-shielding part 292 can be smaller than the width of the portion of the second type of third color resist 312c extending to the upper surface of the second light-shielding part 292. However, the embodiments of this application are not limited to this, and the widths of the portions of the second type of first color resist 312a, the second type of second color resist 312b, and the third type of third color resist 312c extending to the upper surface of the second light-shielding part 292 can be the same.

[0067] In some embodiments, such as Figure 2 , Figure 3 As shown, the thickness of the first light-shielding portion 291 is greater than the thickness of the first color resist portion 311; and / or, the thickness of the second light-shielding portion 292 is less than the thickness of the second color resist portion 312. By making the thickness of the first light-shielding portion 291 greater than the thickness of the first color resist portion 311, the distance between the upper surface of the first light-shielding portion 291 and the substrate 21 can be greater than the distance between the upper surface of the first color resist portion 311 and the substrate 21, further improving the privacy protection effect and the display effect of the display panel; by making the thickness of the second light-shielding portion 292 less than the thickness of the second color resist portion 312, the distance between the upper surface of the second light-shielding portion 292 and the substrate 21 can be less than the distance between the upper surface of the second color resist portion 312 and the substrate 21, further improving the normal display effect.

[0068] In some embodiments, such as Figure 2 , Figure 3 As shown, the thickness L8 of the second type of color resist 312 is less than the thickness L6 of the first light-shielding part 291. By making the thickness of the second type of color resist 312 less than the thickness of the first light-shielding part 291, the first light-shielding part 291 can block the second type of color resist 312, preventing the second type of color resist 312 from flowing into the area where the first type of color resist 311 is located. This causes the thickness of the first type of color resist 311 and the second type of color resist 312 to become uncontrollable, making it easier to control the privacy protection effect and normal display effect of the display panel.

[0069] Specifically, the thickness L7 of the first type of color resist 311 can be made equal to the thickness L5 of the second light-shielding part 292.

[0070] In some embodiments, the display panel 2 includes a first display mode and a second display mode. When the display panel 2 is configured in the first display mode, the first type of light-emitting part 251 emits light, and when the display panel 2 is configured in the second display mode, the second type of light-emitting part 252 emits light.

[0071] Specifically, when the display panel 2 is configured in the first display mode, the first type of light-emitting part 251 emits light. The area of ​​the first type of light-emitting part 251 is small, and the light emission angle of the first type of light-emitting part 251 is small, so as to achieve the privacy display effect. Furthermore, the viewing angle can be further reduced and the privacy effect can be further improved by adjusting the thickness of the first type of light-emitting part 251, and / or adjusting the thickness of the first pixel definition part 241, and / or adjusting the thickness of the first type of color resist part 311, and / or adjusting the thickness of the first light-shielding part 291.

[0072] Specifically, when the display panel 2 is configured in the second display mode, the second type of light-emitting part 252 emits light. The second type of light-emitting part 252 has a larger area and a larger light-emitting angle, thus achieving a normal display effect. Furthermore, the viewing angle can be further increased and the normal display effect can be further improved by adjusting the thickness of the second type of light-emitting part 252, and / or adjusting the thickness of the second pixel definition part 242, and / or adjusting the thickness of the second type of color resist part 312, and / or adjusting the thickness of the second light-shielding part 292.

[0073] Specifically, by switching between the first display mode and the second display mode, the display panel can be switched between privacy display and normal display.

[0074] Specifically, when the display panel 2 is configured in the first display mode, the second type of light-emitting part 252 may not emit light, and when the display panel 2 is configured in the second display mode, the first type of light-emitting part 251 may not emit light. Independent control of the first type of light-emitting part 251 and the second type of light-emitting part 252 can be achieved through the design of the driving circuit.

[0075] Specifically, it is understandable that the display panel also includes a screen-off mode, in which both the first type of light-emitting part 251 and the second type of light-emitting part 252 may not emit light.

[0076] Specifically, Figure 3The example described uses the case where the lower surfaces of the black matrix layer 29 and the color resist layer 31 are located on the same surface. However, the embodiments of this application are not limited to this. In some display panels, there may be other film layers below the black matrix layer 29, so that the lower surface of different parts of the black matrix layer 29 has different heights. However, the thickness of the black matrix layer 29 is still determined by the plane where the lower surface of the color resist layer 31 is located.

[0077] Specifically, such as Figure 3 As shown in the figure, this application embodiment provides a display panel 2, which includes a substrate 21, a driving circuit layer 22, a pixel electrode layer 23, a pixel definition layer 24, a light-emitting material layer 25, a common electrode layer 26, an encapsulation layer 27, a touch layer 28, a black matrix layer 29, and a color resist layer 31. The display panel 2 may also include a cover plate.

[0078] Specifically, the embodiments of this application do not limit the specific design of the driving circuit layer 22. For example, the driving circuit layer 22 may include an active layer, a gate layer, and a source-drain layer. The driving circuit layer 22 may include various film layers for implementing circuits with low-temperature polysilicon thin-film transistors, or various film layers for implementing circuits with oxide semiconductor transistors, or various film layers for circuits with both low-temperature polysilicon thin-film transistors and oxide semiconductor transistors. The type of thin-film transistor can be a bottom-gate thin-film transistor, a top-gate thin-film transistor, or a top-bottom dual-gate thin-film transistor.

[0079] Specifically, the embodiments of this application do not limit the specific design of the driving circuit layer 22. For example, the touch layer 28 may include two touch metal layers and two touch insulating layers.

[0080] Specifically, it can be understood that the first pixel defining part and the second pixel defining part can be different parts of the same film layer, and there may be no clear boundary between them, only a difference in thickness. Similarly, the first light-blocking part and the second light-blocking part can be different parts of the same film layer, and there may be no clear boundary between them, only a difference in thickness.

[0081] Specifically, when forming the light-emitting material layer, light-emitting parts of different thicknesses can be achieved through multiple printing or vapor deposition; when forming the pixel definition layer, pixel definition parts of different thicknesses can be achieved through multiple exposure processes or semi-transparent processes.

[0082] Specifically, when forming the color resist layer, different thicknesses of color resist can be achieved through multiple exposure processes or semi-transparent processes; when forming the black matrix layer, different thicknesses of light-blocking layers can be achieved through multiple exposure processes or semi-transparent processes.

[0083] Specifically, the embodiments of this application do not limit the shape and size of the first type of sub-pixel 201 and the second type of sub-pixel 202. The shape of the first type of sub-pixel 201 and the second type of sub-pixel 202 can be square, circular or other shapes. At the same time, the shape of the first type of sub-pixel 201 with different light emission colors can be the same or different, and the area of ​​the first type of sub-pixel 201 with different light emission colors can be the same or different. Similarly, the shape of the second type of sub-pixel 202 with different light emission colors can be the same or different, and the area of ​​the second type of sub-pixel 202 with different light emission colors can be the same or different.

[0084] Specifically, the pixel arrangement of the first type of sub-pixel 201 and the second type of sub-pixel 202 is not limited in this application embodiment. The arrangement of the first type of sub-pixel 201 and the second type of sub-pixel 202 can be a diamond arrangement, a RealRGB arrangement, or other similar arrangements.

[0085] Specifically, the above embodiments have provided a detailed description of the display panel from aspects such as the film layer structure of the display panel and the specific design of each layer. It is understood that when there is no conflict between the embodiments, the embodiments can be combined. For example, the distance between the upper surface of the first pixel definition part and the substrate is greater than the distance between the upper surface of the first type of light-emitting part and the substrate; and the distance between the upper surface of the second pixel definition part and the substrate is less than the distance between the upper surface of the second type of light-emitting part and the substrate.
