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] As display technology continues to evolve towards lower power consumption, longer lifespan, and higher display quality, people are placing higher demands on displays in terms of display effects and energy efficiency. In Organic Light-Emitting Diode (OLED) display panels, pixels are typically composed of red, green, and blue sub-pixels. Each sub-pixel emits light independently to achieve the independent display of red, green, and blue colors, thereby obtaining high color fidelity and display clarity. Due to its advantages of high color fidelity and good display clarity, this pixel arrangement has been widely used in high-end display panels.

[0003] In related technologies, to further reduce the power consumption and improve the brightness of display panels, it is necessary to optimize the luminous efficiency of the display panels. However, in the manufacturing process of organic light-emitting diode (OLED) display panels, the shape of the pixel aperture and the spacing between adjacent pixel apertures are constrained by process conditions such as the pixel definition layer. This results in a limited effective aperture area of ​​the light-emitting pixels in the display panel and a low overall aperture ratio, thus hindering further development of display panels in terms of brightness improvement and power consumption optimization.

[0025] Please combine Figure 1 , Figure 2 and Figure 3 This embodiment provides a display panel 1, which can be an Organic Light-Emitting Diode (OLED) display panel. The display panel 1 includes a plurality of pixel units 100 arranged in an array along a first direction X and a second direction Y, wherein the second direction Y intersects the first direction X; wherein, the first direction X can be the length direction of the display panel 1, and the second direction Y can be the width direction of the display panel 1, corresponding to the X and Y directions respectively in the accompanying drawings.

[0026] The pixel unit 100 includes a first sub-pixel 101, a second sub-pixel 102, a third sub-pixel 103, and a fourth sub-pixel 104. The first sub-pixel 101, the second sub-pixel 102, the third sub-pixel 103, and the fourth sub-pixel 104 emit different colors. The colors of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are all different from each other, namely red, green, and blue. By adding the fourth sub-pixel 104 in addition to the red, green, and blue sub-pixels, the total light-emitting aperture area in the pixel unit 100 can be effectively increased, thereby improving the pixel aperture ratio.

[0027] It is understandable that by increasing the pixel aperture ratio of the display panel 1, the proportion of the effective area for light emission per unit pixel area increases. While meeting the same display brightness requirements, the required luminous intensity of each sub-pixel is correspondingly reduced. Therefore, the driving current or luminous efficiency per unit area required by each sub-pixel during operation is reduced, thereby alleviating the current and thermal load on the organic light-emitting material during the light emission process. Since the aging rate of organic light-emitting materials is closely related to their operating current density, reducing the driving load helps slow down the performance degradation process of the light-emitting material. This effectively reduces overall power consumption and extends the lifespan of the light-emitting device 400 and the display panel 1 while ensuring the brightness and display uniformity of the display panel 1.

[0028] Furthermore, the display panel 1 includes a plurality of first sub-pixel columns 110 and a plurality of second sub-pixel columns 120, wherein the plurality of second sub-pixel columns 120 and the plurality of first sub-pixel columns 110 are arranged alternately along the second direction Y; wherein, the first sub-pixel column 110 includes a plurality of first sub-pixels 101 and a plurality of second sub-pixels 102 arranged along the first direction X, and the second sub-pixel column 120 includes a plurality of third sub-pixels 103 and a plurality of fourth sub-pixels 104 arranged along the second direction Y.

[0029] It is understandable that by staggering sub-pixels of different luminous colors within the planes containing the first direction X and the second direction Y, adjacent sub-pixels exhibit a staggered distribution of non-same color and non-same direction in the two-dimensional plane, thus avoiding continuous arrangement of sub-pixels of the same color along a single row or column. Since large areas of continuous color and direction are no longer formed between adjacent sub-pixels, the ineffective gap areas formed by the process spacing limitations of the pixel definition layer 30 are reduced, allowing previously unusable local spaces to be used for luminous areas. Therefore, while maintaining the same pixel size, the effective luminous area within the pixel unit 100 is fully utilized, thereby increasing the pixel aperture ratio and contributing to improved display brightness and reduced power consumption.

[0030] Specifically, the display panel 1 has a plurality of first virtual quadrilaterals 200, each having a first diagonal and a second diagonal. The two endpoints of the first diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively. The two endpoints of the second diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively. The center of the fourth sub-pixel 104 coincides with the intersection of the first and second diagonals. Thus, within the geometric virtual area defined by the two first sub-pixels 101 and the two second sub-pixels 102, a stable and definite setting position is reserved for the fourth sub-pixel 104, which is beneficial to improving the utilization efficiency of the internal space of the display panel 1.

[0031] It should be noted that the two endpoints of the first diagonal coincide with the center point of a first sub-pixel 101 and the center point of a second sub-pixel 102, respectively, and the two endpoints of the second diagonal coincide with the center point of another first sub-pixel 101 and the center point of another second sub-pixel 102, respectively. The first sub-pixel 101 corresponding to the first diagonal and the first sub-pixel 101 corresponding to the second diagonal are not the same first sub-pixel 101, and the second sub-pixel 102 corresponding to the first diagonal and the second sub-pixel 102 corresponding to the second diagonal are not the same second sub-pixel 102. That is, the first and second diagonals of the first virtual quadrilateral 200 connect the center points of the first sub-pixel 101 and the second sub-pixel 102 located at different vertices of the first virtual quadrilateral 200, thus defining the geometric structure of the first virtual quadrilateral 200 together with different first sub-pixels 101 and different second sub-pixels 102.

[0032] It is understood that by placing the fourth sub-pixel 104 at the center of the first virtual quadrilateral 200 formed by the two first sub-pixels 101 and the two second sub-pixels 102, the fourth sub-pixel 104 is spatially located in the geometric center region between adjacent sub-pixels, thereby making full use of the intermediate space that was originally difficult to utilize effectively due to pixel pitch and process limitations. Compared to simply arranging sub-pixels along the row and column direction, this embodiment introduces the geometric constraints of the first virtual quadrilateral 200, allowing the newly added fourth sub-pixel 104 to be placed between existing sub-pixels without additionally increasing the overall size of the pixel unit 100.

[0033] Furthermore, by setting the center of the fourth sub-pixel 104 to coincide with the intersection of the first and second diagonals, the fourth sub-pixel 104 is evenly distributed relative to the surrounding sub-pixels. This facilitates the introduction of additional sub-pixel structures without increasing the pixel density, thereby increasing the number of effective light-emitting pixels per unit display area and improving the utilization rate of the pixel opening 31 of the display panel 1.

[0034] Furthermore, in the first virtual quadrilateral 200, the minimum distance between the fourth sub-pixel 104 and the first sub-pixel 101 is equal to the minimum distance between the fourth sub-pixel 104 and the second sub-pixel 102, so that the spacing between the fourth sub-pixel 104 and the surrounding sub-pixels is uniformly distributed, thereby ensuring the brightness uniformity and image stability of the display panel 1; wherein, the minimum distance between the fourth sub-pixel 104 and the first sub-pixel 101 and the minimum distance between the fourth sub-pixel 104 and the second sub-pixel 102 are both defined as the first distance d1.

[0035] It should be noted that the aforementioned "minimum distance" refers to the minimum straight-line distance between the center of the fourth sub-pixel 104 and the center of the adjacent sub-pixel within the first virtual quadrilateral 200, minus the equivalent radius of the corresponding sub-pixel, forming the edge spacing. This distance characterizes the actual spacing between adjacent sub-pixels in the pixel definition layer 30. By limiting this minimum distance, it can be ensured that the minimum spacing requirements of the pixel definition layer 30 process are met between adjacent sub-pixels, thereby avoiding graphic distortion or process failure caused by excessively small spacing.

[0036] In one embodiment, the plurality of first sub-pixels 101 and the plurality of second sub-pixels 102 are arranged alternately along the first direction X, and the plurality of third sub-pixels 103 and the plurality of fourth sub-pixels 104 are arranged alternately along the first direction X. The first sub-pixels 101, the second sub-pixels 102, the third sub-pixels 103 and the fourth sub-pixels 104 all form a periodic and uniform arrangement structure in the first direction X, thereby avoiding the excessive concentration of sub-pixels with the same emission color in local areas, which is beneficial to improving the uniformity and stability of pixel arrangement.

[0037] Furthermore, the display panel 1 has a plurality of second virtual quadrilaterals 300, each having a third diagonal and a fourth diagonal. The two endpoints of the third diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively, and the two endpoints of the fourth diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively. From a viewing angle along the thickness direction of the display panel 1, the third sub-pixel 103 is located within the second virtual quadrilateral 300, and the center of the third sub-pixel 103 coincides with the intersection of the third and fourth diagonals. This allows for full utilization of the available space within the pixel unit 100, increasing the effective light-emitting panel and further improving the pixel aperture ratio.

[0038] Specifically, in the second virtual quadrilateral 300, the minimum distance between the third sub-pixel 103 and the first sub-pixel 101 is equal to the minimum distance between the third sub-pixel 103 and the second sub-pixel 102, so that the spacing between the third sub-pixel 103 and the surrounding sub-pixels is uniformly distributed, thereby ensuring the brightness uniformity and image stability of the display panel 1; wherein, the minimum distance between the third sub-pixel 103 and the first sub-pixel 101 and the minimum distance between the third sub-pixel 103 and the second sub-pixel 102 are both defined as the second distance d2.

[0039] Furthermore, in the second pixel column, the minimum distance between the adjacent fourth sub-pixel 104 and the third sub-pixel 103 is the third distance d3. The third distance d3, the second distance d2, and the first distance d1 are all greater than or equal to 16 micrometers and less than or equal to 21 micrometers, thereby satisfying the minimum spacing requirement of the pixel definition layer 30 process for the adjacent pixel openings 31. At the same time, it ensures that each sub-pixel is reasonably distributed in the two-dimensional plane, avoiding optical crosstalk or process defects.

[0040] In one embodiment, the light emission colors of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are red, green, and blue, respectively; the light emission color of the fourth sub-pixel 104 includes, but is not limited to, white, yellow, or orange; by introducing the fourth sub-pixel 104 into the pixel unit 100 and selecting different light emission colors according to the functional requirements of the display panel 1, the effective light emission area of ​​the pixel unit 100 can be further increased, thereby increasing the pixel aperture ratio.

[0041] Specifically, the area of ​​the fourth sub-pixel 104 is larger than the area of ​​the first sub-pixel 101, and the area of ​​the fourth sub-pixel 104 is larger than the area of ​​the second sub-pixel 102. This gives the fourth sub-pixel 104 a relatively large effective light-emitting area within the pixel unit 100, allowing it to handle more brightness output during display and compensate for the overall brightness of the pixel unit 100. Therefore, while meeting the same display brightness requirements, the driving current or luminous intensity of the first sub-pixel 101 and the second sub-pixel 102 can be reduced, alleviating their luminous load under high-brightness display conditions. This helps reduce power consumption and extend the lifespan of the corresponding organic light-emitting materials.

[0042] Furthermore, the area of ​​the fourth sub-pixel 104 is smaller than the sum of the areas of the first sub-pixel 101 and the second sub-pixel 102. This ensures that while providing brightness compensation, the light emission ratio of the fourth sub-pixel 104 is reasonably constrained. This can maintain the color balance and color reproduction accuracy of the pixel unit 100 while ensuring the brightness enhancement effect, reduce the risk of white balance shift or color distortion, and improve the stability and consistency of the displayed image.

[0043] Furthermore, the area of ​​the fourth sub-pixel 104 is smaller than that of the third sub-pixel 103, giving the third sub-pixel 103 a larger effective light-emitting area within the pixel unit 100. Since the luminous efficiency of blue sub-pixels is relatively low, by setting the area of ​​the third sub-pixel 103 to the largest sub-pixel area in the pixel unit 100, the driving load on the blue sub-pixels in high-brightness display mode can be reduced while maintaining display brightness. This not only improves the display effect of the display panel 1 but also helps extend the lifespan of the blue sub-pixels.

[0044] When the emission color of the fourth sub-pixel 104 is white, the fourth sub-pixel 104 can serve as a brightness compensation type emission sub-pixel in the pixel unit 100, while the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 serve as complementary color light sources. By adjusting the emission intensity ratio between the first sub-pixel 101 and the second sub-pixel 102, between the first sub-pixel 101 and the third sub-pixel 103, and between the second sub-pixel 102 and the third sub-pixel 103, color difference correction and color temperature adjustment can be achieved, thereby improving the color reproduction accuracy of the display panel 1 and enhancing the eye protection function of the display panel 1.

[0045] Furthermore, when the emission color of the fourth sub-pixel 104 is yellow, the fourth sub-pixel 104 can serve as a color balance and brightness synergistic adjustment type sub-pixel. Yellow light is located in the spectral transition region between red and green light, and its emission components can simultaneously produce brightness compensation effects on the red and green channels. By setting the area of ​​the fourth sub-pixel 104 to be larger than the area of ​​the first sub-pixel 101 and the area of ​​the fourth sub-pixel 104 to be larger than the area of ​​the second sub-pixel 102, the driving load of the red and green sub-pixels can be shared while improving the overall brightness, thereby improving the color balance of the pixel unit in the high-brightness display state.

[0046] Furthermore, the area of ​​the fourth sub-pixel 104 is smaller than the sum of the areas of the first sub-pixel 101 and the second sub-pixel 102, so that the yellow light plays a compensating role in the brightness output without excessively interfering with the color expression of the red and green sub-pixels, thereby helping to maintain the accuracy and sense of hierarchy of the overall color.

[0047] In addition, when the emission color of the fourth sub-pixel 104 is orange, the fourth sub-pixel 104 can be used as a warm color enhancement and functional extension type sub-pixel. Orange light is located between red light and yellow light, and its emission components are closer to the high sensitivity range of the human eye to warm color areas in visual perception. By setting a large orange fourth sub-pixel 104, a higher subjective brightness can be obtained under a lower driving current condition, thereby improving the display brightness performance and enhancing visual comfort without increasing power consumption.

[0048] It should be noted that the fourth sub-pixel 104 with a specific emission color can also be used to implement auxiliary display functions, such as displaying notifications, status indicators, or other auxiliary information; or for sensing functions, such as ambient light detection, brightness adjustment, or light sensing feedback. By selecting the emission color of the fourth sub-pixel 104, the fourth sub-pixel 104 can not only improve the functional diversity of the pixel unit 100, but also provide the display panel 1 with more application flexibility.

[0049] In one embodiment, the display panel 1 includes a substrate 10, a driving circuit layer 20, a pixel definition layer 30, a light-emitting device layer 40, an encapsulation layer 50, a color filter layer 60, a planarization layer 70, and a cover plate 80, which are stacked together.

[0050] The substrate 10 is used to carry and support the thin film structure of the display panel 1, providing overall mechanical stability and preventing deformation during subsequent deposition or encapsulation. The substrate 10 can be a rigid substrate 10 or a flexible substrate 10. When the substrate 10 is a rigid substrate, its material can be a material with excellent mechanical strength and thermal stability, such as metal or glass. When the substrate 10 is a flexible substrate, its material can include at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane-based resin, cellulose resin, silicone resin, polyimide-based resin, and polyamide-based resin to meet the requirements of flexible devices for bending and mechanical compliance.

[0051] The driving circuit layer 20 is disposed on the substrate 10. The driving circuit layer 20 is used to provide driving electrical signals to the light-emitting device layer 40 to control the switching state and light emission brightness of the light-emitting device 400, thereby realizing the image display and color adjustment functions of the display panel 1. The driving circuit layer 20 may include multiple thin-film transistors 21 for independent driving of each light-emitting unit. The thin-film transistors 21 may be etch-block type, back-channel etch type, or classified into bottom-gate thin-film transistors 21, top-gate thin-film transistors 21, etc. according to the position of the gate and the active layer. This embodiment does not limit this. It is understood that the driving circuit layer 20 is a conventional film layer well known to those skilled in the art, and its specific structure will not be described in detail here.

[0052] Specifically, the driving circuit layer 20 may include a semiconductor layer, a gate insulating layer, a gate, an interlayer insulating layer, a source / drain electrode layer, a passivation layer, and a planarization layer stacked on the substrate 10; wherein, the source / drain electrode layer includes a source electrode and a drain electrode spaced apart, and the planarization layer is used to provide a smooth surface, eliminate surface unevenness of the substrate 10 or other layers, and ensure that subsequent layers (such as pixel definition layer 30, light-emitting device layer 40, etc.) can be deposited uniformly, thereby improving the display effect and performance of the display panel 1.

[0053] The pixel definition layer 30 is located on the side of the driving circuit layer 20 away from the substrate 10, and is used to define the light-emitting area of ​​each pixel. The pixel definition layer 30 has multiple pixel openings 31. By setting light-emitting functional structures with different light-emitting colors, such as red, green and blue light-emitting units, in different pixel openings 31, the display effect of full-color images can be achieved.

[0054] The light-emitting device layer 40 includes an anode layer, a light-emitting layer 41, and a cathode layer 42 stacked together. The anode layer is disposed between the pixel definition layer 30 and the driving circuit layer 20. The anode layer includes a plurality of anodes spaced apart. A pixel opening 31 is aligned with a certain anode, and at least a portion of the surface of the anode is exposed in the pixel opening 31 to facilitate subsequent deposition of the light-emitting layer 41 and the formation of electrical contacts. The light-emitting layer 41 is disposed on the anode layer and includes a plurality of light-emitting parts corresponding one-to-one with the plurality of anodes. Each light-emitting part is located in the corresponding pixel opening 31 and is electrically connected to the drain of the thin-film transistor 21 through the anode, thereby realizing independent driving and brightness control of each light-emitting part. The cathode layer 42 is laid entirely on the side of the light-emitting layer 41 away from the anode layer.

[0055] Specifically, the light-emitting device layer 40 includes a plurality of light-emitting devices 400, which are arranged in an array, and each light-emitting device 400 is correspondingly disposed within a pixel opening 31; wherein, the plurality of light-emitting devices 400 includes at least a first light-emitting device 401, a second light-emitting device 402, a third light-emitting device 403, and a fourth light-emitting device 404, and the first light-emitting device 401, the second light-emitting device 402, the third light-emitting device 403, and the fourth light-emitting device 404 emit different colors from each other, thereby respectively being used to realize different colors of light emission display.

[0056] The encapsulation layer 50 is disposed on the side of the light-emitting device layer 40 away from the pixel definition layer 30. The encapsulation layer 50 is used to encapsulate the light-emitting device layer 40 to prevent the anode layer, the light-emitting layer 41 and the cathode layer 42 in the light-emitting device layer 40 from coming into contact with water and oxygen in the air, thereby shortening the service life of the display panel 1.

[0057] The color filter layer 60 is disposed on the side of the encapsulation layer 50 away from the light-emitting device layer 40. The color filter layer 60 includes a black matrix 61 and a plurality of color resist blocks 62. The black matrix 61 has a plurality of through holes 611. One color resist block 62 is disposed in a corresponding through hole 611, and one color resist block 62 is disposed in relation to one light-emitting device 400. The color of the color resist block 62 is the same as the emission color of the corresponding light-emitting device 400, so that the light emitted by the light-emitting device 400 can pass through the corresponding color resist block 62, thereby forming the display light of the desired color.

[0058] Specifically, the plurality of color resist blocks 62 includes a first color resist block 621, a second color resist block 622, a third color resist block 623, and a fourth color resist block 624. The first color resist block 621 is configured to correspond to the first light-emitting device 401, the second color resist block 622 is configured to correspond to the second light-emitting device 402, the third color resist block 623 is configured to correspond to the third light-emitting device 403, and the fourth color resist block 624 is configured to correspond to the fourth light-emitting device 404. The color of the first color resist block 621 is the same as the light-emitting color of the corresponding first light-emitting device 401, the color of the second color resist block 622 is the same as the light-emitting color of the second light-emitting device 402, the color of the third color resist block 623 is the same as the light-emitting color of the third light-emitting device 403, and the color of the fourth color resist block 624 is the same as the light-emitting color of the fourth light-emitting device 404.

[0059] The color filter layer 60 can absorb and suppress ambient light to a certain extent without the need for a polarizer 90, thereby reducing interference caused by ambient light reflection. Compared with traditional display structures that rely on a polarizer 90 for anti-reflection, the color filter layer 60 can replace the function of the polarizer 90 in the display panel 1 in related technologies, thereby reducing transmittance loss caused by the polarizer 90, reducing ambient light reflection, and improving the brightness and image contrast of the display panel 1.

[0060] Furthermore, from a perspective along the thickness direction of the display panel 1, the shapes of the first sub-pixel 101, the second sub-pixel 102, the third sub-pixel 103, and the fourth sub-pixel 104 can all be set to circular, which is beneficial for accurately controlling the size of the pixel opening 31 and the spacing between adjacent sub-pixels in the pixel definition layer 30 process, and reducing process deviations in the photolithography and pattern transfer process.

[0061] Meanwhile, the circular design helps reduce edge electric field concentration and light scattering, resulting in a more uniform light emission distribution and further improving display uniformity and stability. Furthermore, the circular structure makes it easier to achieve a uniform material distribution during vapor deposition or inkjet film formation, helping to reduce edge shadow effects and uneven thickness. Compared to polygonal openings with sharp corners, circular or near-circular openings can reduce the directional differences in light scattering and reflection, thereby mitigating bright spots or color shifts caused by ambient light reflection even without a polarizer.

[0062] The first planarization layer 70 is disposed on the side of the color filter layer 60 away from the encapsulation layer 50 and fills the gap between two adjacent color resist blocks 62. Thus, the first planarization layer 70 provides a smooth surface, eliminates surface unevenness caused by the color resist blocks 62 or other lower film layers, thereby improving the deposition uniformity and bonding accuracy of the film layers.

[0063] The cover plate 80 is disposed on the side of the first planarization layer 70 away from the color filter layer 60. The cover plate 80 includes, but is not limited to, a passivation film, optical adhesive, and a glass cover plate 80. The passivation film covers the first planarization layer 70 to further improve the surface flatness of the first planarization layer 70 and prevent the organic insulating film from absorbing moisture or becoming contaminated. The optical adhesive is used to firmly bond the glass cover plate 80 to the passivation film while ensuring high light transmittance. The glass cover plate 80 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] It should be noted that the display panel 1 may also include a touch layer, which is disposed between the encapsulation layer 50 and the color filter layer 60, and includes a plurality of touch units and an insulating layer covering the touch units. The touch units are disposed on the light-emitting side of the display panel 1 and are used to realize the acquisition and transmission of touch signals. The insulating layer covers the touch units, thereby providing electrical isolation and protection for the touch units and preventing external environmental factors from interfering with the touch signals.

[0065] Specifically, the orthographic projection of the black matrix 61 on the substrate 10 covers the orthographic projection of the touch unit on the substrate 10, thereby preventing the touch unit from being directly exposed in the light emission direction of the display panel 1. This effectively shields the reflected light and stray light generated by the touch structure and reduces the interference of the touch layer on the display light path.

[0066] Please combine Figure 1 , Figure 4 and Figure 5 In one embodiment, the second sub-pixel column 120 includes a plurality of third sub-pixel groups 1030, wherein the third sub-pixel groups 1030 and the fourth sub-pixel 104 are staggered in both the first direction X and the second direction Y; wherein, the third sub-pixel group 1030 includes at least two third sub-pixels 103 spaced apart along the first direction X, thereby forming a periodic repeating arrangement structure of "third sub-pixel group 1030 - fourth sub-pixel 104 - third sub-pixel group 1030" in the first direction X.

[0067] It is understood that by combining multiple third sub-pixel groups 1030 into one group and staggering the third sub-pixel groups 1030 with the fourth sub-pixel 104, sub-pixels of different emitting colors can be orderly distributed in the first direction X and the second direction Y, avoiding the problem of uneven brightness or color stripes caused by long-distance continuous arrangement of sub-pixels of the same color. At the same time, by setting at least two third sub-pixels 103 at intervals along the first direction X in the third sub-pixel group 1030, the necessary process spacing can be reserved between adjacent pixels, which is beneficial to the forming of the pixel definition layer 30 and the evaporation alignment of the light-emitting device 400, thereby improving the manufacturing yield.

[0068] Furthermore, since the third sub-pixel group 1030 includes at least two third sub-pixels 103, multiple light-emitting devices 400 participate in the display of the same luminous color in a local area. When displaying low grayscale or locally bright images, the driving current density of a single sub-pixel can be reduced by sharing the luminous load, thereby slowing down the aging rate of the organic light-emitting material and improving the service life of the display panel 1.

[0069] Meanwhile, the fourth sub-pixel 104 is positioned between two adjacent third sub-pixel groups 1030. When the fourth sub-pixel 104 is configured with a specific emission color (e.g., white, orange, or yellow), it can provide brightness or color compensation between two adjacent third sub-pixel groups 1030, thereby improving the brightness continuity and color uniformity along the first direction X and reducing visual unevenness caused by changes in factor pixel spacing or arrangement period.

[0070] Furthermore, in the first direction X, there is a first spacing L1 between adjacent fourth sub-pixels 104 and third sub-pixels 103, and a second spacing L2 between adjacent third sub-pixels 103, wherein the second spacing L2 is smaller than the first spacing L1, so that the two third sub-pixels 103 form a relatively compact arrangement structure within the third sub-pixel group 1030, while a relatively large spatial interval is formed between the third sub-pixel group 1030 and the fourth sub-pixels 104.

[0071] Specifically, the first spacing L1 is greater than or equal to 16 micrometers and less than or equal to 21 micrometers. The first spacing L1 is relatively large, which provides more sufficient arrangement space for the fourth sub-pixel 104. This is beneficial to reasonably introduce the fourth sub-pixel 104 without causing interference or process risks between adjacent sub-pixels, provided that the minimum process spacing requirement of the pixel definition layer 30 is met.

[0072] It should also be noted that two adjacent third sub-pixels 103 belong to the same third sub-pixel group 1030 and are located within the same pixel unit. Their corresponding pixel openings are presented as continuously arranged opening structures within the group in the pixel definition layer 30. Compared with the pixel opening boundaries between different types of sub-pixels, the opening position relationship between these sub-pixels in the same group is more stable and less affected by photolithography alignment errors and etching side etching. Therefore, it is not necessary to strictly limit them according to the minimum process spacing required between different sub-pixels.

[0073] Therefore, the second spacing L2 between two adjacent third sub-pixels 103 can be appropriately reduced while satisfying the basic forming stability of the pixel definition layer 30, and does not need to be equivalent to the minimum process spacing requirement between the third sub-pixel 103 and the fourth sub-pixel 104. Thus, by differentiating the first spacing L1 and the second spacing L2 in the first direction X, the third sub-pixel group 1030 and the fourth sub-pixel 104 are arranged in a spatially "compact within the group, loose between groups" relationship. This improves the space utilization efficiency within the pixel unit while considering the process feasibility of the pixel definition layer 30, which is beneficial for increasing the pixel aperture ratio and further improving the brightness performance and power consumption of the display panel.

[0074] Furthermore, the display panel 1 has a plurality of second virtual quadrilaterals 300, each having a third diagonal and a fourth diagonal. The two endpoints of the third diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively, and the two endpoints of the fourth diagonal coincide with the center of the first sub-pixel 101 and the center of the second sub-pixel 102, respectively. Along the first direction X, the plurality of second virtual quadrilaterals 300 are arranged sequentially. A third sub-pixel group 1030 is set corresponding to three adjacent second virtual quadrilaterals 300. In the third sub-pixel group 1030 and the corresponding three second virtual quadrilaterals 300, any third sub-pixel 103 in the third sub-pixel group 1030 is located within the area formed by two adjacent second virtual quadrilaterals 300. This results in the third sub-pixel 103 being staggered in the spatial frame formed by the first sub-pixel 101 and the second sub-pixel 102, avoiding concentration within a single second virtual quadrilateral 300.

[0075] Specifically, the plurality of third sub-pixels 103 in the third sub-pixel group 1030 are respectively distributed in the transition region between adjacent second virtual quadrilaterals 300, such that each third sub-pixel 103 is simultaneously constrained by the adjacent first sub-pixel 101 and second sub-pixel 102. The position of the third sub-pixel 103 is more central and balanced relative to the first sub-pixel 101 and the second sub-pixel 102, thereby forming a more uniform sub-pixel arrangement structure inside the pixel unit 100.

[0076] It is understandable that by arranging the third sub-pixel group 1030 across multiple second virtual quadrilaterals 300, rather than confining it to the interior of a single second virtual quadrilateral 300, it can fully utilize the space area originally located at the intersection of two adjacent second virtual quadrilaterals 300, avoiding the occurrence of unused pixel gaps, thereby improving the space utilization rate and effective light-emitting opening area of ​​the pixel unit 100; on the other hand, it helps to reduce the distance difference between the third sub-pixel 103 and the surrounding first sub-pixels 101 and second sub-pixels 102, making the relative spacing between each sub-pixel more balanced, thereby reducing the brightness fluctuation or color unevenness caused by uneven pixel arrangement.

[0077] Furthermore, since the third sub-pixel group 1030 is configured to correspond to multiple second virtual quadrilaterals 300, a continuous and smooth arrangement transition relationship is formed between two adjacent pixel units 100 in the first direction X. This is beneficial to improving the brightness continuity of the display panel 1 in the first direction X or the second direction Y, reducing the visual periodic texture or stripe phenomenon, thereby improving display uniformity.

[0078] In one embodiment, the display panel 1 includes a substrate 10, a driving circuit layer 20, a pixel definition layer 30, a light-emitting device layer 40, an encapsulation layer 50, a polarizer 90, a planarization layer 70, and a cover plate 80, all stacked together.

[0079] The substrate 10 is used to carry and support the thin film structure of the display panel 1, providing overall mechanical stability and preventing deformation during subsequent deposition or encapsulation. The driving circuit layer 20 is disposed on the substrate 10. The driving circuit layer 20 is used to provide driving electrical signals to the light-emitting device layer 40 to control the switching state and brightness of the light-emitting device 400, thereby realizing the image display and color adjustment functions of the display panel 1. The driving circuit layer 20 may include multiple thin film transistors 21 for independent driving of each light-emitting unit.

[0080] Specifically, the driving circuit layer 20 may include a semiconductor layer, a gate insulating layer, a gate, an interlayer insulating layer, a source / drain electrode layer, a passivation layer, and a planarization layer 70 stacked on the substrate 10; wherein, the source / drain electrode layer includes a source and a drain electrode spaced apart, and the planarization layer 70 is used to provide a smooth surface, eliminate surface unevenness of the substrate 10 or other layers, and ensure that subsequent layers (such as pixel definition layer 30, light-emitting device layer 40, etc.) can be deposited uniformly, thereby improving the display effect and performance of the display panel 1.

[0081] The pixel definition layer 30 is located on the side of the driving circuit layer 20 away from the substrate 10, and is used to define the light-emitting area of ​​each pixel. The pixel definition layer 30 has multiple pixel openings 31. By setting light-emitting functional structures with different light-emitting colors, such as red, green and blue light-emitting units, in different pixel openings 31, the display effect of full-color images can be achieved.

[0082] The light-emitting device layer 40 includes an anode layer, a light-emitting layer 41, and a cathode layer 42 stacked together. Specifically, the light-emitting device layer 40 includes a plurality of light-emitting devices 400 arranged in an array, and each light-emitting device 400 is correspondingly disposed within a pixel opening 31. The plurality of light-emitting devices 400 includes at least a first light-emitting device 401, a second light-emitting device 402, and a third light-emitting device 403, and the first light-emitting device 401, the second light-emitting device 402, and the third light-emitting device 403 emit different colors from each other, thereby respectively used to realize different colors of light emission display.

[0083] The encapsulation layer 50 is disposed on the side of the light-emitting device layer 40 away from the pixel definition layer 30. The encapsulation layer 50 is used to encapsulate the light-emitting device layer 40 to prevent the anode layer, the light-emitting layer 41 and the cathode layer 42 in the light-emitting device layer 40 from coming into contact with water and oxygen in the air, thereby shortening the service life of the display panel 1.

[0084] The polarizer 90 is disposed on the side of the encapsulation layer 50 away from the light-emitting device layer 40 and covers the display area where the light-emitting device layer 40 is located. It is used to polarize the ambient light incident on the surface of the display panel 1, thereby suppressing the reflection and scattering of ambient light in the light-emitting device layer 40 and its upper structure, and reducing the interference of external light on the display screen.

[0085] Furthermore, from a viewing angle along the thickness direction of the display panel 1, the shapes of the first sub-pixel 101, the second sub-pixel 102, the third sub-pixel 103, and the fourth sub-pixel 104 are all one of quadrilaterals, hexagons, or octagons.

[0086] It is understandable that by setting the shape of each sub-pixel to a regular or approximately regular polygonal structure, compared with irregular shapes or sharp corner structures, it is more conducive to achieving a stable and controllable pattern boundary during the photolithography forming process of the pixel definition layer 30, thereby improving the consistency of the pattern and the processing yield of the pixel definition layer 30.

[0087] Meanwhile, polygonal subpixels have high tiling efficiency in the plane, which is conducive to achieving a denser arrangement within the limited area of ​​the pixel unit 100, thereby reducing the ineffective gap area between subpixels, reserving a larger effective area for the light-emitting area, and helping to improve the pixel aperture ratio.
