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] Pol-Less (PLP) technology significantly improves the light extraction efficiency of a display panel by removing the polarizer on the light-emitting side, thereby increasing display brightness and reducing panel power consumption. However, eliminating the polarizer results in excessively high reflectivity on the light-emitting side of the display panel, severely impacting display quality. To reduce reflectivity, PLP display panels employ a full-surface black pixel definition layer combined with a black matrix to block the metal pattern and cathode, with openings only in the light-emitting pixel areas for light extraction. This design results in almost zero light transmittance; without special design modifications, the light sensor cannot function properly.

[0003] To improve the light transmittance of the photosensitive area containing the photosensor in a polarizer-free display panel, ensuring proper operation of the sensors, related technologies utilize a wire-wound design to create a light-transmitting area within the photosensitive zone. Holes are also created in the black pixel definition layer and the black matrix to further enhance the transmittance. However, due to design differences between the photosensitive and normal display areas, their brightness differs significantly during operation, necessitating different gamma calibration compensations for each. As the number of photosensors increases, multiple gamma curves need to be designed for individual calibration, extending debugging time and reducing display panel production efficiency.

[0050] This embodiment provides a display panel 1, which includes, but is not limited to, an organic light-emitting diode (OLED) display panel 1. The display panel 1 includes an array substrate 11, a pixel definition layer 12, a light-emitting device layer 13, an encapsulation layer 14, a touch layer 15, and a color filter layer 16 stacked together.

[0051] The array substrate 11 includes a substrate 111, a buffer layer (not shown in the figure), and a driving circuit layer 112. The driving circuit layer 112 is disposed on the side of the buffer layer away from the substrate 111. The substrate 111 may include a first substrate, a spacer layer, and a second substrate stacked sequentially. The first substrate and the second substrate may both be rigid substrates or flexible substrates. The materials of the first substrate and the second substrate may both be materials such as glass, quartz, or polyimide. The material of the spacer layer includes, but is not limited to, materials with water absorption properties such as silicon nitride and silicon oxide.

[0052] The driving circuit layer 112 is used to drive the light-emitting device layer 13 and provide the required electrical signals to control the switching state and brightness of the light-emitting device, thereby realizing the image display and color adjustment of the display panel 1. The driving circuit layer 112 may include multiple pixel circuits 1120. The pixel circuit 1120 includes thin film transistors 11211. The thin film transistors 11211 may be etch-block type, back trench etch type, or classified into bottom gate thin film transistors, top gate thin film transistors, etc. according to the position of the gate and the active layer. This embodiment does not limit this.

[0053] Specifically, the driving circuit layer 112 may include a semiconductor layer 1121, a first gate insulating layer 1122, a first gate 1123, a second gate insulating layer 1124, a second gate 1125, an interlayer insulating layer 1126, a source / drain electrode 1127, a first planarization layer 11281, a bridging layer 1129, a second planarization layer 11282, and a third planarization layer 11283 stacked on the substrate 111. 283 is used to provide a smooth surface, eliminate surface unevenness of the substrate 111 or other layers, and ensure that subsequent layers (such as pixel definition layer 12, light-emitting device layer 13, etc.) can be deposited uniformly, thereby improving the display effect and performance of the display panel 1. It is understood that the driving circuit layer 112 is a conventional film layer well known to those skilled in the art, and its specific structure will not be described in detail here. This embodiment only takes the thin film transistor 11211 as a top gate thin film transistor 11211 as an example to illustrate the technical solution of this application.

[0054] The pixel definition layer 12 is disposed on the side of the driving circuit layer 112 away from the substrate 111, and the pixel definition layer 12 has a plurality of pixel openings 121; wherein, the display panel 1 further includes a spacer layer 17, the spacer layer 17 is disposed on the side of the pixel definition layer 12 away from the driving circuit layer 112, the spacer layer 17 can cover the entire surface of the pixel definition layer 12, and the spacer layer 17 is disposed away from the pixel openings 121.

[0055] The light-emitting device layer 13 includes an anode layer 131, a light-emitting layer 132, and a cathode layer (not shown in the figure) stacked together. The anode layer 131 is disposed between the pixel definition layer 12 and the driving circuit layer 112. The anode layer 131 includes a plurality of anodes 1311 spaced apart. A pixel opening 121 is aligned with a certain anode 1311, and the pixel opening 121 exposes a portion of the upper surface of the anode 1311. The light-emitting layer 132 is disposed on the anode layer 131 and includes a plurality of light-emitting elements corresponding one-to-one with the plurality of anodes 1311. The light-emitting unit 1320 is disposed within the pixel opening 121; the cathode layer is disposed on the side of the light-emitting layer 132 away from the anode layer 131; wherein, the anode 1311 is electrically connected to the thin-film transistor 11211, and the thin-film transistor 11211 controls the current flow to the anode 1311 by adjusting the gate signal, and the anode 1311 provides positive charge to drive the light-emitting unit 1320, and the organic material in the light-emitting unit 1320 recombines under the action of the positive charge of the anode 1311 and the negative charge of the cathode layer to generate electroluminescence and emit visible light.

[0056] The encapsulation layer 14 is disposed on the side of the light-emitting device layer 13 away from the pixel definition layer 12. The encapsulation layer 14 is used to encapsulate the light-emitting device layer 13 to prevent the anode layer 131, the light-emitting layer 132 and the cathode layer in the light-emitting device layer 13 from coming into contact with water and oxygen in the air, thereby shortening the service life of the display panel 1. The encapsulation layer 14 includes at least a first inorganic encapsulation layer 14, a first organic encapsulation layer 14 and a second inorganic encapsulation layer 14 stacked on the pixel definition layer 12. The materials of the first inorganic encapsulation layer 14 and the second inorganic encapsulation layer 14 include, but are not limited to, silicon nitride, silicon oxide or silicon oxynitride. The material of the first organic encapsulation layer 14 includes, but is not limited to, polyacrylate.

[0057] The touch layer 15 is disposed on the side of the encapsulation layer 14 away from the light-emitting device layer 13. The touch layer 15 includes a touch electrode 151 and a touch insulating layer 152. The touch insulating layer 152 is located on the side of the touch electrode 151 away from the encapsulation layer 14. The touch electrode 151 includes multiple touch traces that are crisscrossed. The multiple touch traces form a metal mesh structure and are disposed on the light-emitting side of the display panel 1, thereby balancing touch functionality and optical performance.

[0058] The touch electrode 151 can be either a mutual capacitive or a self-capacitive type. When the touch electrode 151 is self-capacitive, multiple touch traces can form multiple touch electrodes 151 and touch leads connected to the touch electrodes 151, with one touch lead electrically connected to one touch electrode 151. When the touch electrode 151 is mutual capacitive, multiple touch traces can form multiple capacitive driving electrodes and multiple capacitive sensing electrodes. The capacitive driving electrodes and capacitive sensing electrodes are arranged alternately to form multiple touch sensing units. Precise touch positioning is achieved by detecting the capacitance change between the capacitive driving electrodes and the capacitive sensing electrodes. It should be noted that the embodiments described above are merely examples and are not limited thereto. The specific type and structure of the touch electrode 151 can be selected according to actual needs.

[0059] The color filter layer 16 includes a plurality of color resist blocks 161 and a light-shielding layer 162 for spacing the plurality of color resist blocks 161. Each color resist block 161 corresponds to a light-emitting unit 1320, thereby providing color light filtering for a specific wavelength and avoiding color light crosstalk. The light-shielding layer 162 is disposed away from the light-emitting unit 1320 and at least covers the touch electrode 151.

[0060] Specifically, the material of the light-shielding layer 162 may include a light-absorbing material, and this embodiment does not specifically limit the type and refractive index of the light-absorbing material; wherein, the orthographic projection of the light-shielding layer 162 on the substrate 111 covers the orthographic projection of the touch electrode 151 on the substrate 111, thereby using the light-shielding layer 162 to block the touch layer 15, so that ambient light is first absorbed by the light-shielding layer 162 before reaching the touch layer 15, preventing it from directly hitting the touch layer 15, reducing the reflection of ambient light by the touch layer 15, and reducing the reflectivity of the display panel 1 in the touch area.

[0061] Furthermore, the light-shielding layer 162 has multiple first openings 1621, with each first opening 1621 corresponding to one pixel opening 121, thus ensuring that the light-shielding layer 162 does not affect the display effect. It is understood that the metal layer inside the display panel 1 (such as the touch electrode 151) may reflect ambient light entering the panel, thereby interfering with the normal display effect, especially affecting the uniformity in the "ultra-black" mode and reducing the user's visual experience. In this embodiment, by setting the light-shielding layer 162 on the side of the touch layer 15 away from the encapsulation layer 14, and in the thickness direction of the display panel 1, the light-shielding layer 162 is at least... The light-shielding layer 162 covers the touch electrode 151 and is positioned away from the pixel opening 121. By using the light-shielding layer 162 to block the touch electrode 151, ambient light is absorbed by the light-shielding layer 162 before reaching the touch electrode 151, preventing it from directly hitting the touch electrode 151. This reduces the reflection of ambient light by the touch electrode 151, lowers the reflectivity of the display panel 1 in the touch area, and improves the uniformity of the display panel 1 in the "ultimate all-black" mode, further optimizing the user's visual experience. At the same time, the light-shielding layer 162 avoids affecting the normal display effect of the display panel 1.

[0062] Meanwhile, the pixel definition layer 12 can be made of a light-shielding material, and the pixel definition layer 12 can be a black pixel definition layer (BPDL). The pixel definition layer 12 and the light-shielding layer 162 work together to block the driving circuit layer 112 while retaining light emission at the pixel opening 121, thereby improving the light emission efficiency of the display panel 1.

[0063] In addition, the display panel 1 may also include a cover plate (not shown in the figure), which is disposed on the color filter layer 16. The cover plate may include a passivation film and a cover glass (CG) stacked together. The passivation film covers the color filter layer 16, which can increase the leveling of the color filter layer 16 and improve its surface smoothness, thereby improving the display effect. The cover glass is used to protect the inner components of the display panel 1, provide mechanical strength, and enhance the durability and scratch resistance of the display panel 1.

[0064] Please continue to combine Figures 1 to 3In one embodiment, the display panel 1 includes a first display area 100 and a second display area 200. The first display area 100 has a plurality of first type sub-pixels 181, each of which includes a first pixel circuit 11201 and a first light-emitting device 13201, and the first light-emitting device 13201 and the first pixel circuit 11201 are connected. The second display area 200 has a plurality of second type sub-pixels 182, each of which includes a second pixel circuit 11202 and a second light-emitting device 13202. The second display area 200 includes a plurality of first display sub-areas 210 and second display sub-areas 220, and the second display sub-areas 220 are disposed around at least a portion of the first display sub-areas 210.

[0065] The display panel 1 further includes a plurality of first pixel portions 1911, which are located within the first display sub-area 210 and the second display sub-area 220. Each first pixel portion 1911 includes a plurality of second light-emitting devices 13202 of the same emitting color and a second pixel circuit 11202. In the first pixel portion 1911, the plurality of second light-emitting devices 13202 and the second pixel circuit 11202 are connected, thereby reducing the number of second pixel circuits 11202 in the second display area 200 and thus reducing the area occupied by the second pixel circuits 11202 in the second display area 200. The space saved can be used as a light-transmitting area 201 to improve the light transmittance of the second display area 200.

[0066] Specifically, the transmittance of the first display sub-area 210 is greater than that of the second display sub-area 220, and the transmittance of the second display sub-area 220 is greater than that of the first display area 100. The first display sub-area 210 can be used to set optical elements, which can provide sufficient light for the optical elements and improve the sensitivity of the optical elements. The first display sub-area 210 is provided with at least one light-transmitting area 201, and the optical elements can be set corresponding to the light-transmitting area 201.

[0067] The driving circuit layer 112 includes at least a plurality of first pixel circuits 11201 located within the first display area 100, and a plurality of second pixel circuits 11202 located within the second display area 200 and disposed away from the light-transmitting area 201. The first pixel circuit 11201 includes a first driving transistor 11211A, and the second pixel circuit 11202 includes a second driving transistor 11211B. Within the second display area 200, there is a blank area between two adjacent second pixel circuits 11202 for setting the light-transmitting area 201. The light-emitting device layer 13 includes a first light-emitting device 13201 located within the first display area 100, and a second light-emitting device 13202 located within the second display area 200. Both the first light-emitting device 13201 and the second light-emitting device 13202 layers 13 include an anode 1311, a light-emitting unit 1320, and a cathode layer.

[0068] In this design, one first driving transistor 11211A is electrically connected to the anode 1311 of a corresponding first light-emitting device 13201, and one second driving transistor 11211B is electrically connected to the anodes 1311 of a plurality of corresponding second light-emitting devices 13202. The anodes 1311 of the plurality of first light-emitting devices 13201 connected to different first pixel circuits 11201 are spaced apart from each other, and the anodes 1311 of the plurality of second light-emitting devices 13202 connected to the same second pixel circuit 11202 are interconnected. This makes all the first pixel circuits 11201 in the first display area 100 a "one-to-one" design, and at least some of the second pixel circuits 11202 in the second display area 200 a "one-to-many" design. This reduces the number of second pixel circuits 11202 in the second display area 200, further reduces the area occupied by the pixel circuits 1120 in the second display area 200, and thus improves the light transmittance of the second display area 200.

[0069] Meanwhile, by reducing the number of pixel circuits 1120 in the second display area 200, the density of pixel circuits 1120 in the second display area 200 is reduced, which can provide more space for the overall layout of the display panel 1, facilitate more refined pixel arrangement and optical design, and reduce production costs and shorten the manufacturing cycle.

[0070] Furthermore, the pixel definition layer 12 also has a plurality of light-transmitting openings 122 located within the second display area 200. The light-transmitting openings 122 are aligned with the light-transmitting area 201. The light-shielding layer 162 also has a plurality of second openings 1622 located within the second display area 200. The first opening 1621 is set corresponding to the first type of sub-pixel 181 and the second type of sub-pixel 182, thereby ensuring that the functions of different sub-pixels of the display panel 1 are not affected. The second openings 1622 are aligned with the light-transmitting openings 122, thereby ensuring that the light-transmitting area 201 of the optical element in the second display area 200 has sufficient light transmittance, ensuring that the optical element can work normally and accurately collect ambient light information, thereby improving the performance and response speed of the display panel 1.

[0071] Specifically, by controlling the outer diameter of the second opening 1622, the light flux of the light-transmitting area 201 can be controlled, thereby effectively adjusting the light intensity required by the optical element and avoiding the impact of excessive light on the accuracy of the optical element. Specifically, by adjusting the opening size, the light transmittance of the light-transmitting area 201 can be flexibly adjusted under different production requirements, ensuring that the display panel 1 maintains good display brightness and optical element performance in different usage scenarios. Furthermore, by controlling the outer diameter of the second opening 1622, it can be ensured that the light passing through the light-transmitting area 201 is limited to the area required by the optical element, so that the light-transmitting area 201 is only displayed at a specific location on the display panel 1 (such as the edge or non-core display area). This reduces the impact of the light-transmitting area 201 on the visual effect and prevents an excessively large second opening 1622 from exposing the light-transmitting area 201 or interfering with the aesthetics of the display area.

[0072] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 ;in, Figure 4 This is a schematic diagram of the first gamma curve and the second gamma curve provided in the embodiments of this application.

[0073] In one embodiment, the plurality of first-type sub-pixels 181 are all configured with a first gamma curve, and the plurality of second-type sub-pixels 182 in the plurality of first-pixel portions 1911 are all configured with a second gamma curve. The voltages corresponding to the same gray level in the first gamma curve and the second gamma curve are a first voltage and a second voltage, respectively. The first voltage is greater than the second voltage, thereby keeping the display brightness of the first display area 100 and the second display area 200 consistent and improving the overall display effect of the display panel 1. Furthermore, by configuring at least a portion of the second pixel circuits 11202 in the entire second display area 200 to use the same set of gamma curves, a unified debugging and calibration standard can be adopted for at least a portion of the second pixel circuits 11202 in the second display area 200, without having to adjust different gamma curves for each second pixel circuit 11202 individually, thereby reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0074] Specifically, both the first driving transistor 11211A and the second driving transistor 11211B are P-type thin-film transistors. It can be understood that in a P-type thin-film transistor, when the voltage (or gate voltage) increases, the gate generates a stronger reverse electric field on the hole channel between the source and drain, resulting in a reduction in the hole concentration in the channel, thereby reducing the current flowing through the channel. Therefore, by adjusting the voltage, precise control of the current can be achieved, enabling the display panel to achieve the expected brightness and color performance.

[0075] It is understandable that the "one-drive-multiple" design can lead to insufficient brightness in corresponding sub-pixels. That is, when a single pixel circuit drives multiple sub-pixels of the same color simultaneously, its current output capability is limited, causing the connected sub-pixels to fail to reach the preset high brightness value. This results in the display brightness of this area being inconsistent with the display brightness of other normally driven (e.g., "one-drive-one" design) display areas, thus affecting the overall display effect. In this embodiment, by setting both the first driving transistor 11211A and the second driving transistor 11211B to be P-type thin-film transistors, and by setting the first voltage to be greater than the second voltage, from... The current flowing through the first driving transistor 11211A of the first pixel circuit 11201 and the second driving transistor 11211B of the second pixel circuit 11202 per unit time is differentiated by design, so that the current flowing through the second driving transistor 11211B per unit time is greater, thereby improving the current output capability of the second pixel circuit 11202. This is beneficial to improving the display brightness of the second type of sub-pixels 182 electrically connected to the second pixel circuit 11202 in the second display area 200, so that the display brightness of the first display area 100 and the second display area 200 are consistent, thereby improving the overall display effect of the display panel 1.

[0076] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figures 7a to 7d ;in, Figure 5 Provided for the embodiments of this application Figure 1 A schematic diagram of a local cross-section corresponding to point O-Oˋ; Figure 6 This is a schematic diagram showing the arrangement of sub-pixels in the first and second display areas provided in an embodiment of this application. Figure 7a Provided for the embodiments of this application Figure 6 Enlarged view of point A in the middle; Figure 7b Provided for the embodiments of this application Figure 6 Enlarged view of point B in the middle; Figure 7c Provided for the embodiments of this application Figure 6 Enlarged view of point C in the middle; Figure 7d Provided for the embodiments of this application Figure 6 Enlarged diagram of point D in the middle.

[0077] In one embodiment, the plurality of first display sub-regions 210 include a first sub-region 211 and a second sub-region 212. Both the first sub-region 211 and the second sub-region 212 are provided with a plurality of first repeating units 191. The first repeating unit 191 includes a first pixel portion 1911 and a light-transmitting portion 1912. The number of first repeating units 191 per unit area in the first sub-region 211 is greater than the number of first repeating units 191 per unit area in the second sub-region 212. This allows for the use of a unified debugging and calibration standard for the first sub-regions 211 and the second sub-regions 212 of different sizes, reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0078] Both the first sub-region 211 and the second sub-region 212 can be optical element regions, which are used to house optical elements and provide necessary optical functions. Specifically, each optical element region is provided with a plurality of first pixel portions 1911 and a plurality of light-transmitting portions 1912. One first pixel portion 1911 and one light-transmitting portion 1912 constitute the first repeating unit 191. The light-transmitting portion 1912 is located within the light-transmitting area 201. The light-transmitting portion 1912 is arranged corresponding to the optical element and can provide sufficient light to the optical element, which is beneficial to improving the sensitivity of the optical element.

[0079] It is understandable that by setting the number of the first repeating units 191 per unit area in the first sub-region 211 to be greater than the number of the first repeating units 191 per unit area in the second sub-region 212, the first sub-region 211 and the second sub-region 212 can correspond to different optical elements. That is, the transmittance of different regions can be adjusted according to the number of the first repeating units 191 to adapt to different optical elements. The size of the light-transmitting area 201 can be flexibly optimized according to the light requirements of the optical elements. For example, the optical elements in the first sub-region 211 may require higher light transmittance to ensure that they can fully receive and process external light signals when working. Therefore, by increasing the number of the first repeating units 191 in the first sub-region 211, the number of light-transmitting parts 1912 in this region is increased, thereby providing a larger light flux to meet the requirements of high-sensitivity optical elements.

[0080] Meanwhile, compared with the existing technology, as the number of optical elements increases, it is necessary to design gamma curves and perform individual calibrations for each optical element, which greatly prolongs the debugging time, increases the workload of manual calibration in the production process, and reduces the production efficiency of the display panel 1. In this embodiment, multiple first pixel units 1911 are provided in both the first sub-region 211 and the second sub-region 212, and multiple second light-emitting devices 13202 and a second pixel circuit 11202 are connected in each first pixel unit 1911, thereby realizing the unified voltage drive of multiple second type sub-pixels 182 in the first sub-region 211 and the second sub-region 212. Specifically, the second type sub-pixels 182 in the multiple first pixel units 1911 are all configured with second gamma curves, thereby avoiding setting different gamma curves for each optical element, reducing the manual adjustment work in the calibration process, and thus improving the production efficiency of the display panel 1.

[0081] Furthermore, the configuration of a unified gamma curve also helps to optimize the display effect of the display panel 1. It is understood that since the sub-pixels in different areas use the same voltage and calibration standard, the brightness and color consistency of each part of the display panel 1 is ensured, and the color difference problem caused by different gamma curves is avoided.

[0082] It should be noted that this embodiment only uses the second display area 200 including a first sub-area 211 and a second sub-area 212 as an example for illustration. In another embodiment, the second display area may include a first sub-area, a second sub-area, and a third sub-area. Each of the first sub-area, the second sub-area, and the third sub-area is provided with a plurality of first repeating units. The first repeating unit includes a first pixel portion and a light-transmitting portion. The light transmittance of the first sub-area, the light transmittance of the second sub-area, and the light transmittance of the third sub-area can be flexibly adjusted according to actual needs. The first sub-area, the second sub-area, and the third sub-area can all be optical element areas. The optical element areas are used to set optical elements and provide necessary optical functions. The setting of multiple sub-areas allows the display panel to flexibly adjust the light transmittance and pixel layout according to the needs of different optical elements.

[0083] Please continue to combine Figures 1 to 7d In one embodiment, both the first sub-region 211 and the second sub-region 212 are provided with a plurality of first pixel rows 1901 and a plurality of light-transmitting rows 1902. The plurality of first pixel rows 1901 and the plurality of light-transmitting rows 1902 are arranged alternately along a first direction Y. Each first pixel row 1901 includes a plurality of first pixel portions 1911 spaced apart along a second direction X. Each light-transmitting row 1902 includes a plurality of light-transmitting portions 1912 spaced apart along a second direction X. This ensures the display effect of the first sub-region 211 and the second sub-region 212 while giving the first sub-region 211 and the second sub-region 212 sufficient light-transmitting area to meet the light transmittance requirements of optical elements.

[0084] One of the light-transmitting portions 1912 is disposed between two adjacent first pixel portions 1911, so that the light-transmitting portions 1912 are evenly distributed and do not interfere with the pixel layout of the display area. In the display panel 1 with optical elements, the "blind spot" of the optical element area can be effectively reduced and its sensitivity improved. It should be noted that the "blind spot" refers to the area in the optical element area where the optical element cannot receive enough light due to insufficient light-transmitting area 201 or blockage, so that the area cannot effectively sense or respond to external light signals.

[0085] It should be noted that this embodiment takes the first direction as... Figure 7a The Y direction and the second direction are Figure 7a Taking the X direction as an example, let's illustrate this; specifically, in... Figure 7a In the diagram, the Y direction represents the vertical direction of the display panel 1, and the X direction represents the horizontal direction of the display panel 1. The first direction Y is perpendicular to the second direction X. Through the above definition of directions, the arrangement of sub-pixels in different display areas and their distribution in the display panel 1 can be clearly described.

[0086] Furthermore, since the light-transmitting portion 1912 is disposed adjacent to the first pixel portion 1911, the shape and size of the light-transmitting portion 1912 can be controlled to improve the light utilization efficiency of the optical element, which helps to improve the overall performance of the display panel 1.

[0087] Please continue to combine Figures 1 to 7d In one embodiment, the second display area 200 further includes a plurality of second repeating units 192, which are arranged around at least a portion of the plurality of first repeating units 191. Each second repeating unit 192 includes a second pixel portion 1921. The structure of the second pixel portion 1921 is the same as that of the first pixel portion 1911. The second type of sub-pixels 182 in the plurality of second pixel portions 1921 are all configured with a second gamma curve, thereby enabling at least a portion of the second pixel circuits 11202 in the entire second display area 200 to be configured to use the same set of gamma curves. This allows for the application of a unified debugging and calibration standard to at least a portion of the second pixel circuits 11202 in the second display area 200.

[0088] Specifically, the second repeating unit 192 includes a second pixel portion 1921, the structure of which is the same as that of the first pixel portion 1911, so that the pixel layout of the second repeating unit 192 is consistent with or similar to that of the first repeating unit 191, ensuring the continuity and consistency of the display effect within the second display area 200, and enabling the second type of sub-pixels 182 in the plurality of second pixel portions 1921 and the second type of sub-pixels 182 in the plurality of first pixel portions 1911 to adopt a unified debugging and calibration standard.

[0089] Furthermore, the second display area 200 is provided with a plurality of second pixel rows 1903, which are spaced apart along the first direction Y. Each second pixel row 1903 includes a plurality of second repeating units 192 spaced apart along the second direction X. The number of second repeating units 192 in adjacent second pixel rows 1903 may be the same or different, thereby providing flexibility and adjustability for the pixel layout of the second display area 200.

[0090] Within the second display area 200, by controlling the number of the second repeating units 192 between the boundary of the first sub-area 211 and the second display area 200, the number of the second repeating units 192 between the boundary of the second sub-area 212 and the second display area 200, and the number of the second repeating units 192 between the first sub-area 211 and the second sub-area 212, it can be ensured that similar display effects are achieved in different areas of the second display area 200, thus avoiding the problem of inconsistent local display effects.

[0091] Meanwhile, by adjusting the number of the second repeating units 192, the area of ​​the second display area 200 can be controlled; for example, by increasing or decreasing the number of the second repeating units 192, the second display area 200 can be expanded or reduced horizontally or vertically to meet different display requirements; specifically, for display devices with different numbers of light-emitting elements, the size of the second display area 200 can be flexibly adjusted to adapt to the needs of different application scenarios.

[0092] It should be noted that in a display panel that uses multiple optical elements, the display panel typically needs to be set with multiple optical element areas, with one optical element area corresponding to one optical element. Since the functional requirements, shapes, and sizes of the multiple optical elements may differ, the shape, size, light transmittance, and other parameters of the multiple optical element areas will also be different. For example, if the display panel includes multiple irregularly shaped optical element areas, multiple gamma curves need to be designed for these optical element areas for individual calibration, which prolongs the debugging time and reduces the production efficiency of the display panel.

[0093] It is understood that, by controlling the number of the second repeating units 192, this embodiment can integrate multiple optical element areas with complex geometries into a second display area 200 with a regular shape. The structure of the second pixel part 1921 is the same as that of the first pixel part 1911. The second type of sub-pixels 182 in the multiple second pixel parts 1921 and the second type of sub-pixels 182 in the multiple first pixel parts 1911 are all configured with a second gamma curve. This enables at least a portion of the second pixel circuits 11202 in the entire second display area 200 to be configured to use the same set of gamma curves. A unified debugging and calibration standard can be adopted for at least a portion of the second pixel circuits 11202 in the second display area 200, without having to adjust different gamma curves for each second pixel circuit 11202 individually. This reduces the workload of manual calibration, shortens the debugging time, and improves the production efficiency of the display panel 1.

[0094] Please continue to combine Figures 1 to 7dIn one embodiment, the second display area 200 is provided with a plurality of third-type sub-pixels 183, each of which includes a first pixel circuit 11201 and a third light-emitting device (not shown in the figure), wherein the third light-emitting device and the first pixel circuit 11201 are connected; wherein each of the plurality of third-type sub-pixels 183 is configured with a first gamma curve, thereby effectively shortening the individual adjustment time for each of the third-type sub-pixels 183 during the production process and improving production efficiency.

[0095] Specifically, in the first display area 100, a first light-emitting device 13201 and a first pixel circuit 11201 are connected; in the second display area 200, a third light-emitting device and a first pixel circuit 11201 are connected; the plurality of first-type sub-pixels 181 and the plurality of third-type sub-pixels 183 are all configured with a first gamma curve; in the second display area 200, in the first pixel portion 1911, a plurality of second light-emitting devices 13202 and a second pixel circuit 11202 are connected; the second-type sub-pixels 182 in the plurality of first pixel portions 1911 are all configured with a second gamma curve.

[0096] The first type of sub-pixel 181, the second type of sub-pixel 182 and the third type of sub-pixel 183 include, but are not limited to, one or more of red sub-pixel 1801, green sub-pixel 1802 and blue sub-pixel 1803. That is, the first display area 100 and the second display area 200 are provided with red sub-pixel 1801, green sub-pixel 1802 and blue sub-pixel 1803.

[0097] Specifically, the first type of sub-pixel 181 includes a red sub-pixel 1801, a green sub-pixel 1802, and a blue sub-pixel 1803 located within the first display area 100; the second type of sub-pixel 182 includes any one of the red sub-pixel 1801, green sub-pixel 1802, and blue sub-pixel 1803 located within the second display area 200; and the third type of sub-pixel 183 includes any two of the red sub-pixel 1801, green sub-pixel 1802, and blue sub-pixel 1803 located within the second display area 200 that are different from the second type of sub-pixel 182. In this embodiment, the second type of sub-pixel 182 includes a blue sub-pixel 1803 located within the second display area 200, and the third type of sub-pixel 183 includes a red sub-pixel 1801 and a green sub-pixel 1802 located within the second display area 200, as an example for illustration.

[0098] It is understood that the red sub-pixel 1801, green sub-pixel 1802, and blue sub-pixel 1803 in the first display area 100 all adopt a "one-to-one" design, and the red sub-pixel 1801 and green sub-pixel 1802 in the second display area 200 also adopt a "one-to-one" design; multiple second light-emitting devices 13202 and a second pixel circuit 11202 are connected, and the blue sub-pixel 1803 in the second display area 200 all adopt a "one-to-many" design. Thus, the brightness of the entire display panel 1 can be adjusted through two sets of gamma curves without adjusting the gamma curve for each sub-pixel individually, reducing the workload of manual calibration and making the manufacturing process of the display panel 1 simpler and more efficient.

[0099] Please continue to combine Figures 1 to 7d In one embodiment, within the first display area 100 and the second display area 200, a plurality of red sub-pixels 1801 are arranged in multiple rows and columns in the first direction Y and the second direction X, a plurality of blue sub-pixels 1803 are arranged in multiple rows and columns in the first direction Y and the second direction X, and a plurality of green sub-pixels 1802 are arranged in multiple rows and columns in the first direction Y and the second direction X; wherein, between any two adjacent rows of blue sub-pixels 1803, there is a row of red sub-pixels 1801 and a row of green sub-pixels 1802; any row of blue sub-pixels 1803 and the adjacent row of red sub-pixels 1801 are alternately arranged, and any row of red sub-pixels 1801 and the adjacent row of green sub-pixels 1802 are arranged in a one-to-one correspondence.

[0100] Specifically, within the first sub-region 211 and the second sub-region 212, along the first direction Y, the first pixel portion 1911 includes two adjacent blue sub-pixels 1803. The two adjacent blue sub-pixels 1803 are electrically connected to the same second pixel circuit 11202. Along the first direction Y, a light-transmitting portion 1912 is provided between the two adjacent first pixel portions 1911. This allows the blue sub-pixels 1803 in the first sub-region 211 and the second sub-region 212 to adopt a "one-drive-multiple" design, reducing the number of pixel circuits 1120 in the second display area 200. This reduces the coverage area of ​​the driving circuit, allowing the pixel circuits 1120 in the first sub-region 211 and the second sub-region 212 to easily avoid the light-transmitting area 201. Therefore, a light-transmitting portion 1912 can be provided between the two adjacent first pixel portions 1911, achieving local high light transmittance while providing sufficient space for the pixel circuits 1120.

[0101] Furthermore, within the second display area 200, along the first direction Y, the second pixel portion 1921 includes two adjacent blue sub-pixels 1803. The two adjacent blue sub-pixels 1803 are electrically connected to the same second pixel circuit 11202, thereby enabling the blue sub-pixels 1803 within the second display area 200 to adopt a "one-to-many" design. It can be understood that, since the structure of the second pixel portion 1921 is the same as that of the first pixel portion 1911, the blue sub-pixels 1803 in the plurality of second pixel portions 1921 and the blue sub-pixels in the plurality of first pixel portions 1911 can all be configured with a second gamma curve. This allows at least a portion of the second pixel circuits 11202 within the entire second display area 200 to be configured to use the same set of gamma curves. A unified debugging and calibration standard can be adopted for at least a portion of the second pixel circuits 11202 within the second display area 200, without the need to adjust different gamma curves for each second pixel circuit 11202 individually. This reduces the workload of manual calibration, shortens the debugging time, and improves the production efficiency of the display panel 1.

[0102] It should be noted that any color sub-pixel located in the second display area 200 can adopt a "one-to-many" design. Of course, only some color sub-pixels can adopt a "one-to-many" design. This embodiment only uses the blue sub-pixel 1803 adopting a "one-to-many" design as an example for illustration.

[0103] Please see Figure 8 and Figure 9 ;in, Figure 8 This is a schematic diagram of the structure of the display device provided in the embodiments of this application; Figure 9 This is a cross-sectional schematic diagram of the display device provided in an embodiment of this application.

[0104] This embodiment also provides a display device 2, which includes the display panel 1 described in any of the above embodiments.

[0105] It is understood that the display panel 1 has been described in detail in the above embodiments, and will not be repeated here.

[0106] The display device 2 also includes a housing 21, which is integrated with the display panel 1 to provide support, fixation and protection for the display panel 1.

[0107] In specific applications, the display device 2 can be at least one of the following devices with display functions: smartphone, tablet computer, mobile phone, video phone, e-book reader, desktop computer, laptop computer, netbook, workstation, server, personal digital assistant, portable media player, MP3 player, mobile medical device, camera, game console, digital camera, car navigation system, electronic billboard, ATM or wearable device.

[0108] Furthermore, the display device 2 also includes at least two optical elements 22, one of which is disposed corresponding to the first sub-area 211 and the other of which is disposed corresponding to the second sub-area 212; in some embodiments, the optical element 22 includes, but is not limited to, one of a camera, an infrared sensor, an ambient light sensor or a fingerprint reader.

[0109] In this embodiment, the light transmittance of the second display area 200 of the display panel 1 is improved, which increases the sensitivity of the optical element 22. At the same time, the display effect of different areas of the display device 2 remains consistent.
