Description

Technical Field

[0001] This application relates to the field of displays, and in particular to a display panel and display device. Background Technology

[0002] With the development of display technology, under-display camera (CUP) technology has been widely used in display devices. CUP technology places the camera below the display screen; the area where the camera is located is called the CUP transparent area, and the other area is called the normal display area. However, at wide viewing angles, such as greater than 30°, the brightness of the normal area and the CUP transparent area differs, making the CUP transparent area visible and affecting the user experience. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a display panel and display device that improves the display consistency between the first display area and the second display area, avoids the first display area being too bright and easily visible, and improves the user experience. The specific solution is as follows:

[0004] In a first aspect, this application provides a display panel, the display panel including a first display area and a second display area, wherein the light transmittance of the first display area is greater than the light transmittance of the second display area, the display panel comprising:

[0005] A substrate, a pixel definition layer, and a raised structure layer are stacked sequentially along the display direction of the display panel; the pixel definition layer has multiple openings arranged in an array, the openings are used to set sub-pixels, and within the first display area, the multiple openings include adjacent first openings and second openings, with at least one raised structure between the first opening and the second opening.

[0006] Secondly, embodiments of this application also provide a display device, including the aforementioned display panel.

[0007] This application provides a display panel and a display device. The display panel includes a first display area and a second display area. The light transmittance of the first display area is greater than that of the second display area. The display panel includes a substrate, a pixel definition layer, and a raised structure layer stacked sequentially along the display direction of the display panel. The pixel definition layer has multiple openings arranged in an array. The openings are used to set sub-pixels. In the first display area, the multiple openings may include adjacent first and second openings. At least one raised structure is provided between the first and second openings. The raised structure can raise the edges of the first and second openings, which can block the light emitted by the sub-pixels in the first and second openings, thereby interfering with large-angle light emission, reducing the light emission brightness of the sub-pixels in the first display area, narrowing the difference in light transmittance between the first and second display areas, improving the display consistency between the first and second display areas, preventing the first display area from being too bright and easily visible, and improving the user experience.

[0022] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] Secondly, this application provides a detailed description in conjunction with schematic diagrams. When detailing the embodiments of this application, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this application. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0025] As described in the background section, at wide viewing angles, the brightness of the Normal area and the CUP (Chip-through-Panel) area differs, making the CUP area visible and impacting the user experience. The display panel includes a CUP area and a Normal area surrounding it. In the Normal area, the pixel size is normal, and a TPOT (Touch Panel on TFE) pattern is placed above the pixels. TPOT technology places the touch layer on the thin-film encapsulation layer, and this touch layer above the pixels somewhat blocks light emitted from the pixels. In the CUP area, the pixel size is smaller, and there is no touch layer or TPOT pattern above the pixels. Therefore, at wide viewing angles, the TPOT pattern affects light emission from the Normal area but not from the CUP area. The transmittance of the CUP area is greater than that of the Normal area, which may result in the CUP area being brighter than the Normal area, making it visible and affecting the user experience.

[0026] Based on the above technical problems, this application provides a display panel and a display device. The display panel includes a first display area and a second display area. The light transmittance of the first display area is greater than that of the second display area. The display panel includes a substrate, a pixel definition layer, and a raised structure layer stacked sequentially along the display direction of the display panel. The pixel definition layer has multiple openings arranged in an array. The openings are used to set sub-pixels. In the first display area, the multiple openings may include adjacent first and second openings. At least one raised structure is provided between the first and second openings. The raised structure can raise the edges of the first and second openings, which can block the light emitted by the sub-pixels in the first and second openings, thereby interfering with large-angle light emission, reducing the brightness of the sub-pixels in the first display area, narrowing the difference in light transmittance between the first and second display areas, improving the display consistency between the first and second display areas, preventing the first display area from being too bright and easily visible, and improving the user experience.

[0027] For ease of understanding, the following detailed description, in conjunction with the accompanying drawings, describes a display panel and display device provided in an embodiment of this application.

[0028] refer to Figure 1 The image shown is a top view of a display panel provided in an embodiment of this application. The display panel includes a first display area 100 and a second display area 200. Both the first display area 100 and the second display area 200 have multiple pixel units 300. Display can be performed in the first display area 100 and the second display area 200 by driving the pixel units 300 to emit light. The light transmittance of the first display area 100 is greater than that of the second display area 200. The first display area 100 can be a CUP (Chip-to-Plate) transparent area, and the second display area 200 can be a normal area.

[0029] refer to Figure 2 The diagram shown is a schematic diagram of the structure of a display panel provided in an embodiment of this application. The display panel includes a substrate 101, a pixel definition layer 102, and a raised structure layer. The substrate 101, the pixel definition layer 102, and the raised structure layer are stacked sequentially along the display direction of the display panel. The substrate 101 can be a polyimide (PI) layer, etc., and the substrate 101 can be rigid or flexible.

[0030] The pixel definition layer 102 is used to define pixel areas and non-pixel areas. The pixel definition layer 102 has multiple openings arranged in an array, and sub-pixels can be set in the openings. The sub-pixels can be red (R), green (G), blue (B), etc. Within the first display area 100, the multiple openings can include adjacent first openings 103 and second openings 104. At least one protrusion structure 105 can be provided between the first opening 103 and the second opening 104. The protrusion structure 105 can be a PS support pillar, etc.

[0031] The raised structure 105 can raise the edges of the first opening 103 and the second opening 104, which can block the light emitted by the sub-pixels in the first opening 103 and the second opening 104, thereby interfering with the large-angle light emission, reducing the light emission brightness of the sub-pixels in the first display area 100, narrowing the difference in light transmittance between the first display area 100 and the second display area 200, improving the display consistency of the first display area 100 and the second display area 200, and preventing the first display area 100 from being too bright and easily visible, thus improving the user experience.

[0032] In the embodiments of this application, reference is made to Figure 3 The diagram shown is a structural schematic of another display panel provided in an embodiment of this application. The display panel further includes a driving circuit layer 115, a planarization layer 116, a first electrode layer 117, a display layer 118, a second electrode layer 119, a thin film encapsulation layer 120, an insulating layer 121, a protective layer 122, and a polarizer layer 123.

[0033] Specifically, the driving circuit layer 115, the planarization layer 116 and the first electrode layer 117 are located between the substrate 101 and the pixel definition layer 102, and the display layer 118, the second electrode layer 119, the thin film encapsulation layer 120, the insulating layer, the protective layer and the polarizer layer are located on the side of the raised structure layer away from the substrate 101.

[0034] Specifically, the driving circuit layer 115 includes a gate dielectric layer 124, an interlayer insulating layer 125, a passivation layer 126, and multiple thin-film transistors (TFTs). The TFTs can be low-temperature polycrystalline oxide (LTPO) TFTs. Each TFT includes a gate 127 and an active layer 128. The gate dielectric layer 124 is located between the gate 127 and the active layer 128. A portion of the active layer located at the projection position of the gate 127 onto the active layer 128 serves as a channel region. Source and drain regions are located on either side of the channel region. The source and drain regions can include a source region on one side of the channel region and a drain region on the other side. The source region can be connected to the source electrode 129 via a source line, and the drain region can be connected to the drain electrode 130 via a drain line. The drain electrode 130 can be connected to the first electrode layer 117 via a connection structure, thereby driving the sub-pixel to emit light. An interlayer insulating layer 125, which can be an inorganic or organic material, can be disposed above the gate 127. The passivation layer 126 is located on the source electrode 129 and the drain electrode 130 of the thin-film transistor. The passivation layer 126 can be formed of inorganic materials such as silicon oxide or silicon nitride, or it can be formed of organic materials. The planarization layer 116 is located above the driving circuit layer 115 and has a planarization function.

[0035] Specifically, multiple thin-film transistors can be disposed in the first display area, and the multiple thin-film transistors can be connected to the first electrode layer 117 located in the first display area and the first electrode layer 117 located in the second display area, thereby driving the sub-pixels of the first display area and the second display area to emit light.

[0036] Specifically, the first electrode layer 117, the display layer 118, and the second electrode layer 119 can form a sub-pixel. The first electrode layer 117 can be used to form an anode, the display layer 118 is used to emit light, and the second electrode layer 119 can be used to form a common cathode.

[0037] The display layer 118 may include a hole transport layer, an emissive layer and an electron transport layer stacked sequentially along the display direction of the display panel. The emissive layer is located in the pixel area. Different materials of the emissive layer can be used to emit light of different colors, so that the sub-pixels to which the emissive layer belongs have different colors. Multiple sub-pixels can share the same hole transport layer and electron transport layer.

[0038] Specifically, the thin-film encapsulation layer 120 can seal the display layer 118 to prevent moisture and oxygen from corroding the sub-pixels. A touch electrode layer 108 can be set in the insulating layer 121 to realize the touch function. In specific implementation, a self-capacitance method or a mutual capacitance method can be used. The touch electrode layer 108 can be a single-layer touch electrode or a double-layer touch electrode, or a metal mesh touch electrode. The metal mesh touch electrode includes multiple metal electrode traces extending along two intersecting directions. The metal electrode traces extending in different directions intersect to form a mesh. The specific implementation can be selected according to the actual situation.

[0039] In the embodiments of this application, there may be one protrusion structure 105 or multiple protrusion structures 105 between the first opening 103 and the second opening 104, which is not specifically limited here.

[0040] In one possible implementation, a plurality of protruding structures 105, denoted as first protruding structure 106 and second protruding structure 107, are provided between the first opening 103 and the second opening 104, wherein the first protruding structure 106 is closer to the first opening 103 and the second protruding structure 107 is closer to the second opening 104. (Reference) Figure 4 The diagram shown is a structural schematic of another display panel provided in an embodiment of this application. It has a first protrusion structure 106 near the first opening 103 and a second protrusion structure 107 near the second opening 104.

[0041] The first protruding structure 106 raises the edge of the first opening 103, blocking the light emitted by the sub-pixels in the first opening 103. The second protruding structure 107 raises the edge of the second opening 104, blocking the light emitted by the sub-pixels in the second opening 104. Especially at wide viewing angles, this reduces the difference in light transmittance between the first display area 100 and the second display area 200. Moreover, the presence of protruding structures near each opening reduces the brightness of the sub-pixels in each opening, maximizing the reduction of the light transmittance of the first display area 100 and resulting in higher display consistency between the first display area 100 and the second display area 200.

[0042] Specifically, the first protrusion structure 106 can be a strip structure, and the extension direction of the strip structure can be a direction perpendicular to the direction from the first opening 103 to the second opening 104, which can increase the degree of light blocking of the sub-pixel, thereby improving the display consistency of the first display area 100 and the second display area 200.

[0043] refer to Figure 5 The image shown is a top view of a display panel provided in an embodiment of this application. The display panel includes a plurality of R sub-pixels, G sub-pixels, and B sub-pixels arranged in an array. Figure 4 for Figure 5In the cross-sectional view along the AA direction, there is a first protruding structure 106 with a strip-like structure near the first opening 103, and a second protruding structure 107 with a strip-like structure near the second opening 104. Of course, multiple first protruding structures 106 with strip-like structures can be provided around the first opening 103 to block the light emitted from the sub-pixels in the first opening 103 from multiple directions.

[0044] Specifically, the first protrusion structure 106 can also be an annular structure surrounding the first opening 103. It can be a circular ring, a square ring, or a closed annular structure, such as a semi-ring.

[0045] When the first protrusion structure 106 is a closed annular structure surrounding the first opening 103, it can block the light emission of the sub-pixel from all directions, greatly reducing the brightness of the sub-pixel and thus improving the display consistency between the first display area 100 and the second display area 200. (Reference) Figure 6 The image shown is a top view of another display panel provided in this application embodiment. The first protrusion structure 106 surrounding the first opening 103 is annular, and the second protrusion structure 107 surrounding the second opening 104 is also annular.

[0046] refer to Figure 7 As shown, Figure 6 In the cross-sectional view along the AA direction, there is a first protrusion structure 106 around the first opening 103 and a second protrusion structure 107 around the second opening 104.

[0047] Of course, a raised structure can be provided around each opening in the first display area 100 to block the light emission brightness of each opening and improve the display consistency between the first display area 100 and the second display area 200.

[0048] In this embodiment, sub-pixels of different colors can be set in the opening. The color of the sub-pixels affects the size of the protruding structure near the opening. By adjusting the size of the protruding structure according to the color adaptability of the sub-pixels, the light transmittance of the first display area 100 can be adjusted more accurately, thereby improving the display consistency between the first display area 100 and the second display area 200.

[0049] In one possible implementation, within the first display area 100, when the sub-pixel color in the first opening 103 is green and the sub-pixel color in the second opening 104 is red or blue, since the human eye is more sensitive to green, when the green sub-pixel and other color sub-pixels have the same luminous brightness, the human eye can more easily perceive the green. Therefore, the distance between the first opening 103 and the first protrusion structure 106 can be smaller than the distance between the second opening 104 and the second protrusion structure 107. The first protrusion structure 106 is closer to the first opening 103, and the first protrusion structure 106 can have a greater occlusion effect on the sub-pixels in the first opening 103, thus reducing the luminous brightness of the green sub-pixels to a greater extent. This makes the luminous brightness of the green sub-pixels perceived by the human eye more consistent with that of other color sub-pixels, improving the display uniformity of the first display area 100 and the second display area 200, and improving the user experience.

[0050] refer to Figure 6 As shown, the first opening 103 has a green sub-pixel, and the second opening 104 has a red sub-pixel. The distance between the first opening 103 and the first protrusion structure 106 is L1, and the distance between the second opening 104 and the second protrusion structure 107 is L2. With L1 < L2, the first protrusion structure 106 is closer to the green sub-pixel, and the light-blocking effect of the first protrusion structure 106 on the green sub-pixel is stronger than the light-blocking effect of the second protrusion structure 107 on the red sub-pixel, thereby improving the display uniformity of the first display area 100 and the second display area 200.

[0051] In one possible implementation, when the sub-pixel color in the first opening 103 within the first display area 100 is green and the sub-pixel color in the second opening 104 is red or blue, the height of the first protrusion structure 106 can be set to be greater than the height of the second protrusion structure 107. In this way, by setting a higher protrusion structure near the green sub-pixel, the higher first protrusion structure 106 can block green light emitted at a large angle to a greater extent, reduce the brightness of green light to a greater extent, and make the brightness of green sub-pixels perceived by the human eye more consistent with that of other color sub-pixels, thereby improving the display consistency between the first display area 100 and the second display area 200 and improving the user experience.

[0052] Furthermore, the first protrusion structure 106 has a sidewall facing the first opening 103 and a sidewall away from the first opening 103. The sidewall facing the first opening 103 reflects and refracts the light emitted by the sub-pixels in the first opening 103, thereby blocking the light. The sidewall away from the first opening 103 does not affect the light emitted by the sub-pixels in the first opening 103. Therefore, the tilt of the sidewall facing the first opening 103 can be adjusted to adjust the brightness of the sub-pixels in the first display area 100. The tilt of the sidewall away from the first opening 103 is not specifically limited here.

[0053] In one possible implementation, when the sub-pixel color in the first opening 103 is green and the sub-pixel color in the second opening 104 is red or blue within the first display area 100, the angle between the sidewall of the first protrusion structure 106 facing the first opening 103 and the display direction of the display panel can be denoted as the first angle, and the angle between the sidewall of the second protrusion structure 107 facing the second opening 104 and the display direction of the display panel can be denoted as the second angle.

[0054] When the sidewall of the first protrusion structure 106 facing the first opening 103 is steeper, the sidewall facing the first opening 103 has a stronger effect on blocking the light emission of the sub-pixel. Therefore, the first angle can be set to be smaller than the second angle. In this way, compared with the sidewall of the second protrusion structure 107 facing the second opening 104 blocking the light emission of the red or blue sub-pixel, the sidewall of the first protrusion structure 106 facing the first opening 103 will block the light emission of the green sub-pixel more strongly, blocking the large-angle emitted green light and reducing the brightness of the green light to a greater extent. This makes the light emission brightness of the green sub-pixel perceived by the human eye more consistent with that of other color sub-pixels, improving the display uniformity of the first display area 100 and the second display area 200, and improving the user experience.

[0055] In this embodiment, the display panel may further include a touch electrode layer 108, as shown in the reference. Figure 8 The diagram shown is a schematic representation of another display panel provided in this application embodiment. The touch electrode layer 108 is located within the second display area 200 and is situated on the side of the raised structure layer away from the substrate 101. (Refer to...) Figure 9 As shown, this is a top view of another display panel provided in an embodiment of this application. The touch electrode layer 108 includes multiple touch electrode traces 109. The multiple touch electrode traces 109 can form a mesh structure as touch electrodes to realize touch function.

[0056] Multiple touch electrode traces 109 can extend along the first direction. A third protrusion structure 110 can be provided between the first opening 103 and the second opening 104. The third protrusion structure 110 also extends in the first direction. In this way, the third protrusion structure 110 can not only raise the edges of the first opening 103 and the second opening 104, but also block the light emitted by the sub-pixels in the first opening 103 and the second opening 104, thereby interfering with the large-angle light emission, reducing the light emission brightness of the sub-pixels in the first display area 100, narrowing the difference in light transmittance between the first display area 100 and the second display area 200, improving the display consistency of the first display area 100 and the second display area 200, and preventing the first display area 100 from being too bright and easily visible. Furthermore, since the extension direction of the third protrusion structure 110 is the same as the extension direction of the touch electrode trace 109, and the arrangement of the third protrusion structure 110 is the same as the arrangement of the touch electrode trace 109, the blocking effect of the third protrusion structure 110 on the light emission of the sub-pixels in the first display area 100 is the same as the blocking effect of the touch electrode trace 109 on the light emission of the sub-pixels in the second display area 200, thereby further improving the display consistency of the first display area 100 and the second display area 200.

[0057] In one possible implementation, multiple touch electrode traces 109 can extend along a second direction and a third direction, wherein the second direction is perpendicular to the third direction and is the same as the first direction, as shown in the reference. Figure 10 As shown, this is a top view of another display panel provided in an embodiment of this application. The touch electrode traces 109 extend in the second and third directions to form a mesh structure.

[0058] The first opening 103 and the second opening 104 are adjacent in the second direction, and the third protrusion structure 110 extends in the second direction. The first opening 103 and the third opening 230 are adjacent in the third direction. There is a fourth protrusion structure 111 between the first opening 103 and the third opening 230. The fourth protrusion structure 111 extends in the third direction. In this way, the third protrusion structure 110 and the fourth protrusion structure 111 are both set between the minimum spacing of the openings and extend in the second and third directions, which is consistent with the extension direction of the touch electrode trace 109. This makes the blocking effect of the protrusion structure on the light emission of the sub-pixels in the first display area 100 the same as the blocking effect of the touch electrode trace 109 on the light emission of the sub-pixels in the second display area 200, thereby improving display consistency.

[0059] It is understandable that the extension direction of the touch electrode traces 109 can be set according to actual needs. Multiple touch electrode traces 109 can be arranged into a mesh structure. The shape of the mesh structure can be rectangular, cross-shaped, or rounded rectangle, and can be set according to actual needs. No specific limitation is made here.

[0060] In this embodiment of the application, within the second display area 200, a plurality of openings include adjacent fourth opening 112 and fifth opening 113, and a fifth protrusion structure 114 may be provided between the fourth opening 112 and the fifth opening 113. (See reference) Figure 11 The image shown is a top view of another display panel provided in an embodiment of this application. Within the second display area 200, there is a fourth opening 112, a fifth opening 113, and a fifth protruding structure 114.

[0061] Specifically, within the second display area 200, in the BB direction, the openings located on opposite sides of the fifth protrusion structure 114 are the fourth opening 112 and the fifth opening 113. The distance between the fifth protrusion structure 114 and the fourth opening 112 is denoted as the first distance L1, and the distance between the fifth protrusion structure 114 and the fifth opening 113 is denoted as the second distance L2. Within the first display area 100, a first protrusion structure 106 is located between the first opening 103 and the second opening 104. In the AA direction, the openings located on opposite sides of the first protrusion structure 106 are the first opening 103 and the second opening 104. The distance between the first protrusion structure 106 and the first opening 103 can be denoted as the third distance L3, and the distance between the first protrusion structure 106 and the second opening 104 can be denoted as the fourth distance L4.

[0062] refer to Figure 12 As shown, Figure 11 In the cross-sectional view along the BB direction, within the second display area 200, there is a first distance L1 between the fifth protrusion structure 114 and the fourth opening 112, and within the first display area 100, there is a third distance L3 between the first protrusion structure 106 and the first opening 103. The third distance L3 can be set to be less than the first distance L1, so that the protrusion structure in the first display area 100 is closer to the adjacent opening, and the protrusion structure in the second display area 200 is farther from the adjacent opening. This satisfies both the requirement that the protrusion structure in the first display area 100 blocks pixel emission from the opening, and the requirement that the protrusion structure in the second display area 200 provides support without blocking pixel emission.

[0063] Within the first display area 100, the first protruding structure 106 is closer to the first opening 103 or the second opening 104. Within the second display area 200, the fifth protruding structure 114 does not need to block the light emission of the pixels in the opening and can be kept as far away as possible from the fourth opening 112 and the fifth opening 113. For example, it can be located in the middle of the fourth opening 112 and the fifth opening 113. In this way, the first distance L1 and the second distance L2 are relatively close, while the difference between the third distance L3 and the fourth distance L4 is relatively large. The difference between the first distance L1 and the second distance L2 is smaller than the difference between the third distance L3 and the fourth distance L4. Thus, it satisfies both the requirement that the protruding structure blocks the light emission of the pixels in the opening in the first display area 100 and the requirement that the protruding structure does not block the light emission of the pixels in the opening in the second display area 200.

[0064] In practical applications, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 can all be in the same direction, for example, all in the BB direction, as shown in the reference. Figure 13 As shown, within the second display area 200, the fifth protrusion structure 114 is located in the middle of the fourth opening 112 and the fifth opening 113. The first distance L1 and the second distance L2 are relatively close. Within the first display area 100, there are adjacent first openings 103 and sixth openings 131 in the BB direction. Between the first opening 103 and the sixth opening 131, there is a first protrusion structure 106. The third distance L3 is the distance between the first opening 103 and the first protrusion structure 106, and the fourth distance L4 is the distance between the sixth opening 131 and the first protrusion structure 106. The first protrusion structure 106 is closer to the first opening 103. The third distance L3 is smaller, and the fourth distance L4 is larger. By reasonably setting the position of the protrusion structure in the first display area, the brightness difference between the first display area and the second display area in this direction can be better compensated, thereby improving the display consistency of the display panel.

[0065] refer to Figure 14 The image shown is a top view of another display panel provided in this application embodiment. A protruding structure can be provided in the first display area 100 between adjacent openings, i.e., at the minimum spacing between openings. The extension direction of the protruding structure is consistent with the extension direction of the touch electrode trace 109, thereby reducing the light emission brightness of the sub-pixels in the first display area. In the first display area 100, the protruding structures are located at the diagonal position of the openings, which are relatively far from each opening and are relatively sparse, thereby avoiding blocking the light emission of the pixels in the openings, reducing the difference in light transmittance between the first display area and the second display area, and improving the display consistency between the first display area and the second display area.

[0066] In this embodiment, when the diameter of the first opening 103 is larger than the diameter of the second opening 104, the third protrusion structure 110 can be divided into a first part near the first opening 103 and a second part near the second opening 104. In a direction perpendicular to the first direction, the length of the first part is greater than the length of the second part. Thus, by adjusting the light-blocking range of the protrusion portion relative to the opening diameter, the first part provides a larger light-blocking range for the first opening 103, thereby reducing the luminous brightness of the large-diameter first opening 103 to a greater extent, and improving the display consistency between the first display area 100 and the second display area 200. Specifically, refer to... Figure 15 As shown, this is a top view of another display panel provided in an embodiment of this application, where the width of the protruding structure around the larger diameter opening is wider.

[0067] In this embodiment of the application, the raised structure in the first display area 100 can be black. Compared with the transparent raised structure, the black raised structure can absorb light and block light to a greater extent, thereby improving display consistency.

[0068] In this embodiment, the sidewall of the protruding structure can have a single plane, which simplifies the manufacturing process. Alternatively, the sidewall can have multiple planes, such as a stepped sidewall with multiple inclined surfaces, which allow adjustment of sub-pixel emission. Of course, the sidewall of an opening can also have one or more planes.

[0069] Specifically, at least two heights can be achieved using a single halftone mask, meaning that a single organic film (mask) can create more than two heights. For example, using a halftone mask can also achieve three different heights in raised structures and openings, which can be used to adjust the light emission.

[0070] refer to Figure 16 As shown, this is a schematic diagram of the structure of another display panel provided in an embodiment of this application. The sidewalls of the first opening 103 and the second opening 104 are stepped structures, and the sidewall of the protruding structure 105 facing the first opening 103 is also stepped.

[0071] This application provides a display panel including a first display area and a second display area. The light transmittance of the first display area is greater than that of the second display area. The display panel includes a substrate, a pixel definition layer, and a raised structure layer stacked sequentially along the display direction of the display panel. The pixel definition layer has multiple openings arranged in an array, which are used to set sub-pixels. In the first display area, the multiple openings may include adjacent first and second openings, and at least one raised structure is provided between the first and second openings. The raised structure can raise the edges of the first and second openings, thereby blocking the light emitted by the sub-pixels in the first and second openings, interfering with large-angle light emission, reducing the brightness of the sub-pixels in the first display area, narrowing the difference in light transmittance between the first and second display areas, improving the display consistency between the first and second display areas, preventing the first display area from being too bright and easily visible, and improving the user experience.

[0072] A display panel based on the above embodiments, such as Figure 17 As shown in the figure, this application embodiment also provides a display device, which includes the aforementioned display panel. The display device has a display area AA and a non-display area NA. The non-display area surrounds the display area. The display area AA includes a first display area 100 and a second display area 200. The display area is used to house an OLED. The first display area 100 can house a camera. The non-display area NA is used to house wiring. By using the aforementioned display panel, the display device can reduce the difference in light transmittance between the first display area and the second display area, improve the display consistency between the first display area and the second display area, avoid the first display area being too bright and easily visible, and improve the user experience.
