[0002] OLED (Organic Light Emitting Diode) display panel is one of the hot topics in the current display panel research field. Compared with liquid crystal display panels, OLED display panels have the advantages of low energy consumption, low cost, self-luminescence, wide viewing angle and fast response speed.

[0003] The display effect of the OLED display panel in the related art needs to be improved. Summary of the invention

[0004] Based on this, it is necessary to provide a pixel arrangement structure, a display panel and a display device that can improve the display effect.

[0005] According to one aspect of the present application, an embodiment of the present application provides a pixel arrangement structure, including multiple pixel groups; the pixel groups include at least one first sub-pixel, at least one second sub-pixel and at least one third sub-pixel, the light-emitting area of ​​the first sub-pixel is surrounded to form a first accommodating space, and the second sub-pixel and the third sub-pixel are arranged in the first accommodating space.

[0006] The above-mentioned pixel arrangement structure, by enclosing the light-emitting area of ​​the first sub-pixel to form a first accommodating space, and arranging the second sub-pixel and the third sub-pixel in the first accommodating space, can optimize the edge color fringing phenomenon during display, reduce the display granularity, optimize the white light ratio, and improve the display effect.

[0007] In one embodiment, the shape of the first accommodation space is polygonal or circular or elliptical or quasi-circular; optionally, the shape of the first accommodation space is rectangular; optionally, the shape of the first accommodation space is hexagonal; optionally, the light-emitting area of ​​the first sub-pixel has a plurality of first outer sides and a plurality of first inner sides, and the first inner sides correspond to the first outer sides one by one; optionally, the first inner sides and the first outer sides corresponding thereto are parallel to each other and arranged at intervals; optionally, the first sub-pixel has a plurality of openings that penetrate its light-emitting area and communicate with the first accommodation space; optionally, any opening penetrates a first outer side and a first inner side corresponding to the first outer side; optionally, any opening penetrates two first outer sides connected to each other and two first inner sides connected to each other corresponding to the two first outer sides. With this design, the shape of the light-emitting area of ​​the first sub-pixel and the first accommodation space enclosed thereby is more regular, which is convenient for processing and manufacturing, and at the same time, it is beneficial to reduce the spacing between two adjacent pixel groups in the pixel arrangement structure, thereby improving the aperture ratio of the display panel.

[0008] In one embodiment, the second sub-pixel and the third sub-pixel are arranged at intervals from each other; optionally, the second sub-pixel and the third sub-pixel are arranged on two opposite sides of the first accommodation space, respectively. With this design, the second sub-pixel and the third sub-pixel can be manufactured and formed more conveniently.

[0009] In one embodiment, the light-emitting area of ​​the second sub-pixel surrounds at least part of the light-emitting area of ​​the third sub-pixel; optionally, the light-emitting area of ​​the second sub-pixel has a recessed portion on a side close to the third sub-pixel that is recessed inwardly in a direction away from the third sub-pixel, and the light-emitting area of ​​the third sub-pixel has a protruding portion on a side close to the second sub-pixel that is protruding outwardly in a direction toward the second sub-pixel, and the recessed portion surrounds at least part of the protruding portion; optionally, the light-emitting area of ​​the second sub-pixel is a U-shaped structure, and the light-emitting area of ​​the third sub-pixel is a T-shaped structure; optionally, the light-emitting area of ​​the first sub-pixel has a plurality of first outer sides and a plurality of first inner sides, and the first inner sides are connected to the first outer sides. The sides correspond one to one, the light-emitting area of ​​the second sub-pixel has at least one first side on the side away from the third sub-pixel, the first side corresponds one to one with at least part of the first inner side, and the first side and the first inner side corresponding thereto are parallel to each other and are arranged at intervals; optionally, the light-emitting area of ​​the first sub-pixel has multiple first outer sides and multiple first inner sides, the first inner side corresponds one to one with the first outer side, the light-emitting area of ​​the third sub-pixel has at least one second side on the side away from the second sub-pixel, the second side corresponds one to one with at least part of the first inner side, and the second side and the first inner side corresponding thereto are parallel to each other and are arranged at intervals. By setting a recessed portion in the light-emitting area of ​​the second sub-pixel and a protruding portion in the light-emitting area of ​​the third sub-pixel, so that the recessed portion surrounds at least part of the protruding portion, the edge color edge phenomenon during display can be optimized and the display graininess can be reduced. At the same time, the light-emitting area of ​​the second sub-pixel and the light-emitting area of ​​the third sub-pixel are mutually embedded, which is conducive to color mixing between the two and improves display uniformity.

[0010] In one embodiment, the light-emitting area of ​​the second sub-pixel is surrounded to form a second accommodating space, and the third sub-pixel is arranged in the second accommodating space; optionally, the shape of the second accommodating space is polygonal, circular, elliptical or quasi-circular; optionally, the shape of the second accommodating space is rectangular; optionally, the shape of the second accommodating space is hexagonal; optionally, the light-emitting area of ​​the second sub-pixel has multiple second outer edges and multiple second inner edges, the second inner edges correspond to the second outer edges one-to-one, and the second inner edges and the corresponding second outer edges are parallel to each other and spaced apart; optionally, the light-emitting area of ​​the first sub-pixel has multiple first outer edges and multiple first inner edges, the first inner edges correspond to the first outer edges one-to-one, the second outer edges correspond to the first inner edges one-to-one, and the second outer edges and the corresponding first inner edges are parallel to each other and spaced apart. By enclosing the light-emitting area of ​​the second sub-pixel to form a second accommodating space, and arranging the third sub-pixel in the second accommodating space, the edge color fringing phenomenon during display can be further optimized and the display graininess can be reduced. At the same time, the shape of the light-emitting area of ​​the second sub-pixel and the second accommodating space enclosed by it is more regular, which is convenient for processing and manufacturing, and is beneficial to reducing the distance between the second sub-pixel and the first sub-pixel, thereby improving the aperture ratio of the display panel.

[0011] In one embodiment, the shape of the light-emitting area of ​​the third sub-pixel is polygonal, circular, elliptical or quasi-circular; optionally, the shape of the light-emitting area of ​​the third sub-pixel is rectangular; optionally, the shape of the light-emitting area of ​​the third sub-pixel is hexagonal; optionally, the light-emitting area of ​​the third sub-pixel has a plurality of third side edges, the third side edges correspond to the second inner side edges one by one, and the third side edges and the corresponding second inner side edges are parallel to each other and arranged at intervals. In this way, the spacing between the third sub-pixel and the second sub-pixel is reduced, and the aperture ratio of the display panel is further improved.

[0012] In one embodiment, the symmetry axis of the light-emitting area of ​​the second sub-pixel is collinear with the symmetry axis of the light-emitting area of ​​the third sub-pixel; optionally, the symmetry axis of the light-emitting area of ​​the first sub-pixel, the symmetry axis of the light-emitting area of ​​the second sub-pixel, and the symmetry axis of the light-emitting area of ​​the third sub-pixel are collinear. This design makes the arrangement of each sub-pixel in the pixel group more uniform, which is conducive to improving the overall display uniformity and ensuring the linearity of the display.

This design makes the arrangement of pixel groups more uniform, and the sub-pixels of the same color are evenly and regularly arranged, which is conducive to improving the overall display uniformity. In two adjacent columns of pixel groups, the pixel groups are arranged flush, which is more convenient for manufacturing, or the pixel groups are arranged staggered, which improves the aperture ratio of the display panel.

[0019] The above-mentioned display panel, by enclosing the electrode portion of the first sub-pixel to form a third accommodating space, and the electrode portion of the second sub-pixel and the electrode portion of the third sub-pixel are arranged in the third accommodating space, can accommodate the second sub-pixel and the third sub-pixel in the light-emitting area of ​​the first sub-pixel, optimize the edge color fringing phenomenon during display, reduce the display granularity, optimize the white light ratio, and improve the display effect.

In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0059] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0060] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0061] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0062] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0063] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0064] Organic Light-Emitting Diode (OLED) display devices have been listed as a display technology with great development prospects due to their advantages such as thinness, lightness, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high light emission efficiency and flexible display.

[0065] For a better understanding, some explanations are given before going into detail:

[0066] Sub-pixels: Sub-pixels are composed of small grids that display images. These small grids have a clear position and assigned color values, and the clear position is determined by the pixel arrangement, and the assigned color value is determined by the pixel circuit. The color and position of these small grids determine the appearance of the displayed image.

[0067] Resolution: Display resolution refers to the precision of the displayed image, specifically, how many sub-pixels the display can display. For example, common resolutions are HD: 720*1280, FHD: 1080*1920, QHD: 1440*2560, and UHD (2K\4K): 2160*3840. Taking FHD as an example, it means that there are 1080 R sub-pixels, 1080 G sub-pixels, and 1080 B sub-pixels in one direction, and 1920 R sub-pixels, 1920 G sub-pixels, and 1920 B sub-pixels in the other direction.

[0068] PPI (Pixels Per Inch): Also known as pixel density, it indicates the number of pixels in one inch. For example, FHD resolution and 5-inch size have 441 PPI. Therefore, it can be considered that under the premise that the size of the display is certain, the higher the resolution, the higher the PPI.

[0069] Aperture ratio: Aperture ratio refers to the ratio of the effective light-transmitting area to the total area of ​​a pixel, that is, the ratio between the area of ​​the part through which light passes after removing the wiring and transistor parts of each sub-pixel and the overall area of ​​each sub-pixel. The higher the aperture ratio, the more efficient the light passing through.

[0070] It should be pointed out that those skilled in the art should know that based on the pixel arrangement structure of the present application, each sub-pixel should be distributed as evenly as possible.

[0071] Figure 1 This is a cross-sectional view of the overall structure of a display panel 100 provided in one embodiment of the present application. Figure 2 A schematic diagram of a pixel arrangement structure in a display panel 100 provided in one embodiment of the present application is shown in FIG. Figure 3 A schematic diagram of the structure of a pixel group 110 in a pixel arrangement structure provided in an embodiment of the present application.

[0072] See also Figures 1 to 3, an embodiment of the present application provides a display panel 100, which includes a display area and a non-display area. The display area displays an image by arranging a plurality of sub-pixels in a pixel arrangement structure located in the display area. Specifically, the display area may be a rectangle, and the non-display area is arranged around the display area. Of course, the shape and arrangement of the display area and the non-display area include but are not limited to the above examples. For example, when the display panel 100 is used for a wearable device worn on a user, the display area may have a circular shape like a watch; when the display panel 100 is used for display on a vehicle, the display area and the non-display area may adopt, for example, a circular, polygonal or other shape. The display area is provided with a plurality of sub-pixels that emit light of different colors, and the sub-pixel is characterized as the smallest unit for emitting light.

[0073] like Figure 2 and Figure 3 As shown, the pixel arrangement structure in at least one embodiment disclosed in the present application includes a plurality of pixel groups 110; the pixel group 110 includes at least one first sub-pixel 111, at least one second sub-pixel 112 and at least one third sub-pixel 113, the light-emitting area of ​​the first sub-pixel 111 is surrounded to form a first accommodating space 1110, and the second sub-pixel 112 and the third sub-pixel 113 are arranged in the first accommodating space 1110.

[0074] It can be understood that the pixel group 110 refers to the smallest repeating unit repeatedly arranged in the pixel arrangement structure of the display panel 100, and the arrangement of the multiple pixel groups 110 is not limited here. In some embodiments, the multiple pixel groups 110 can be arranged in an array, that is, the centers of the multiple pixel groups 110 are staggered along at least two directions to form an array. For example, the multiple pixel groups 110 can be staggered along a first direction x and a second direction y that intersect each other and are arranged in an array. At this time, the pixel groups 110 are arranged in rows along the first direction x and arranged in columns along the second direction y that intersects the first direction x. Among them, the rows and columns of the pixel groups 110 in the pixel arrangement structure are relative, and the pixel groups 110 arranged in rows can be pixel groups 110 arranged in columns in other embodiments. The angle between the first direction x and the second direction y is not limited. In some embodiments, in particular, the first direction x can be perpendicular to the second direction y.

[0075] Each pixel group 110 includes a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113. The first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel, respectively. Of course, in some other embodiments, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can also be sub-pixels that emit light of other colors besides red, green, and blue, such as white or yellow, which is not limited here.

[0076] It should be understood that different colors of light have different wavelengths. The shorter the wavelength, the higher the energy of the light. High-energy light can easily cause the decay of organic light-emitting materials, making sub-pixels that emit high-energy photons more susceptible to decay. As is known, the wavelength of blue light is shorter than that of red and green light. Therefore, the energy of blue light is higher, and organic light-emitting materials that emit blue light are more susceptible to decay, causing the light emitted in the pixel unit to be easily reddish, resulting in a color shift of white light. The light emitted by each sub-pixel is repeatedly reflected and re-reflected between the anode and cathode through the microcavity effect, amplified and constructively interfered, the brightness of the light is increased, and the color shift is further amplified.

[0077] Therefore, in one embodiment, the light-emitting area of ​​the blue sub-pixel is larger than the light-emitting area of ​​the red sub-pixel and the light-emitting area of ​​the green sub-pixel, so that the display defects caused by the different attenuation rates of the organic light-emitting materials emitting different colors of light can be reduced to a certain extent. Figure 2 and Figure 3 In the illustrated embodiment, the first sub-pixel 111 is a blue sub-pixel, the second sub-pixel 112 is a green sub-pixel, and the third sub-pixel 113 is a red sub-pixel, and the light-emitting area of ​​the first sub-pixel 111 is larger than the light-emitting area of ​​the second sub-pixel 112, and larger than the light-emitting area of ​​the third sub-pixel 113. As for the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113, there is no strict size relationship, and the light-emitting area of ​​the second sub-pixel 112 may be larger than the light-emitting area of ​​the third sub-pixel 113, or the light-emitting area of ​​the third sub-pixel 113 may be larger than the light-emitting area of ​​the second sub-pixel 112.

[0078] In the embodiment of the present application, the light-emitting area of ​​the first sub-pixel 111 is surrounded to form a first accommodating space 1110, and the second sub-pixel 112 and the third sub-pixel 113 are arranged in the first accommodating space 1110. The light-emitting area of ​​the first sub-pixel 111 is surrounded to form the first accommodating space 1110, which means that the light-emitting area of ​​the first sub-pixel 111 is in a hollow ring shape, wherein the ring area is arranged around the hollow area, and the hollow area is the first accommodating space 1110, and the second sub-pixel 112 and the third sub-pixel 113 are both arranged in the first accommodating space 1110.

[0079] In the present application, the specific shapes of the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112, the light-emitting area of ​​the third sub-pixel 113 and the first accommodating space 1110 can be regular or irregular, and are not limited here. The light-emitting areas of the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 are also not limited, but the cross-sectional area of ​​the first accommodating space 1110 should be greater than the sum of the light-emitting areas of the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the light-emitting area of ​​the third sub-pixel 113, so that the first accommodating space 1110 can accommodate the second sub-pixel 112 and the third sub-pixel 113. In other embodiments of the present application, two second sub-pixels 112 and two third sub-pixels 113 can be set in the first accommodating space 1110, and the number of the second sub-pixels 112 and the third sub-pixel 113 can be adjusted according to actual needs.

[0080] The pixel arrangement structure of the embodiment of the present application is such that the light-emitting area of ​​the first sub-pixel 111 is enclosed to form a first accommodating space 1110, and the second sub-pixel 112 and the third sub-pixel 113 are arranged in the first accommodating space 1110. This can optimize the edge color fringing phenomenon during display, reduce the display graininess, optimize the white light ratio, and improve the display effect.

Figure 5 A schematic structural diagram of a first sub-pixel 111 in a pixel arrangement structure provided in another embodiment of the present application.

[0082] Please also read Figures 2 to 5 In the present application, the specific shapes of the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112, and the light-emitting area of ​​the third sub-pixel 113 are not limited. Figure 4 and Figure 5 In the illustrated embodiment, the outer contour of the light-emitting area of ​​the first sub-pixel 111 is a rectangle, and the shape of the first accommodating space 1110 is also a rectangle. On this basis, the light-emitting area of ​​the first sub-pixel 111 has a plurality of first outer sides 1111 and a plurality of first inner sides 1112, the first inner sides 1112 correspond to the first outer sides 1111 one by one, and the first inner sides 1112 and the first outer sides 1111 corresponding thereto are parallel to each other and spaced apart. It is understandable that the number of the first outer sides 1111 and the first inner sides 1112 varies according to the shape of the light-emitting area of ​​the first sub-pixel 111, and is not limited here.

[0083] In other embodiments of the present application, the outer contour shape of the light-emitting area of ​​the first sub-pixel 111 can also be polygonal, circular, elliptical or quasi-circular, and can be, for example, a pentagon, hexagon, octagon or the like. The shape of the first accommodating space 1110 can also be polygonal, circular, elliptical or quasi-circular, and can be, for example, a pentagon, hexagon, octagon or the like.

[0084] The outer contour of the light-emitting area of ​​the first sub-pixel 111 is a rectangle, the four first outer sides 1111 are the edges of the outer contour, the four first inner sides 1112 are the edges of the annular inner contour, the first inner sides 1112 correspond to the first outer sides 1111 one by one, and the first inner sides 1112 and the first outer sides 1111 corresponding thereto are parallel to each other and arranged at intervals. At this time, the area enclosed between the multiple first outer sides 1111 and the multiple first inner sides 1112 is the light-emitting area of ​​the first sub-pixel 111, and the area enclosed inside the multiple first inner sides 1112 is the hexagonal first accommodation space 1110. With this design, the shape of the light-emitting area of ​​the first sub-pixel 111 and the first accommodation space 1110 enclosed thereby are more regular, which is convenient for processing and manufacturing. At the same time, it is beneficial to reduce the distance between two adjacent pixel groups 110 in the pixel arrangement structure, thereby improving the aperture ratio of the display panel 100.

[0085] The light emitting area of ​​the first sub-pixel 111 may be closed or open. In some embodiments, the first sub-pixel 111 has a plurality of openings 1113 that penetrate the light emitting area and communicate with the first receiving space 1110 .

[0086] The number, shape and specific position of the openings 1113 on the first sub-pixel 111 are not limited. In some embodiments, any opening 1113 runs through a first outer side 1111 and a first inner side 1112 corresponding to the first outer side 1111. Figure 4 As shown, illustratively, Figure 4 The shape of the first sub-pixel 111 is a rectangle, having four first outer sides 1111 and four first inner sides 1112 corresponding thereto, and at the same time, an opening 1113 with a rectangular outline is provided on any set of side lines of the first sub-pixel 111, and the opening 1113 passes through one first outer side 1111 and one first inner side 1112 corresponding to the first outer side 1111, so as to communicate with the first accommodation space 1110. Of course, in other embodiments, more openings 1113 are provided on the same set of side lines or other sets of side lines of the first sub-pixel 111.

[0087] The opening 1113 may be disposed on a set of side lines of the first sub-pixel 111, or may be disposed at other positions of the first sub-pixel 111. In other embodiments, any opening 1113 passes through two first outer sides 1111 connected to each other, and two first inner sides 1112 connected to each other corresponding to the two first outer sides 1111. Figure 5 As shown, exemplarily, an opening 1113 with a rectangular outline is provided on any set of vertices of the first sub-pixel 111, and the opening 1113 simultaneously penetrates two first outer sides 1111 connected to each other, and two first inner sides 1112 connected to each other corresponding to the two first outer sides 1111, that is, the opening 1113 penetrates a set of vertices of the first sub-pixel 111, thereby communicating with the first accommodation space 1110. Similarly, in other embodiments, the second sub-pixel 112 and the third sub-pixel 113 may also be provided with openings, which will not be described in detail here.

[0088] Please continue reading Figure 3 In the pixel group 110 , the second sub-pixel 112 and the third sub-pixel 113 are disposed in the first receiving space 1110 , and the second sub-pixel 112 and the third sub-pixel 113 may be spaced apart from each other in the first receiving space 1110 .

[0089] Furthermore, the second sub-pixel 112 and the third sub-pixel 113 are respectively disposed on two opposite sides of the first receiving space 1110. Figure 3 As shown, illustratively, the second sub-pixel 112 and the third sub-pixel 113 may be respectively disposed on two opposite sides of the first accommodating space 1110 in the first direction x. In other embodiments, the second sub-pixel 112 and the third sub-pixel 113 may also be respectively disposed on two sides of the first accommodating space 1110 in the second direction y, or may also be respectively disposed on two sides of the first accommodating space 1110 in other directions.

[0090] Figure 6 Schematic diagram of the structure of the second sub-pixel 112 in the pixel arrangement structure provided in one embodiment of the present application. Figure 7 A schematic diagram of the structure of a third sub-pixel 113 in a pixel arrangement structure provided in one embodiment of the present application.

[0091] As described above, the second sub-pixel 112 and the third sub-pixel 113 are respectively disposed on opposite sides of the first accommodating space 1110. In some embodiments, further, the light-emitting area of ​​the second sub-pixel 112 surrounds at least a portion of the light-emitting area of ​​the third sub-pixel 113, that is, at least a portion of the light-emitting area of ​​the second sub-pixel 112 extends to the periphery of the light-emitting area of ​​the third sub-pixel 113 and wraps up at least a portion of the light-emitting area of ​​the third sub-pixel 113. The proportion of the light-emitting area of ​​the third sub-pixel 113 that is wrapped can be adjusted according to different usage requirements.

[0092] like Figure 6 to Figure 7 As shown, in order to facilitate the light-emitting area of ​​the second sub-pixel 112 to surround at least a portion of the light-emitting area of ​​the third sub-pixel 113, in the present embodiment, the light-emitting area of ​​the second sub-pixel 112 has a recessed portion 1122 on a side close to the third sub-pixel 113 that is concave inwardly toward the direction away from the third sub-pixel 113, and the light-emitting area of ​​the third sub-pixel 113 has a protruding portion 1132 on a side close to the second sub-pixel 112 that is protruding outwardly toward the second sub-pixel 112, and the recessed portion 1122 surrounds at least a portion of the protruding portion 1132.

[0093] like Figure 6 As shown, the concave portion 1122 is concave from the side of the light emitting area of ​​the second sub-pixel 112 close to the third sub-pixel 113 toward the direction away from the third sub-pixel 113, that is, from the side of the light emitting area of ​​the second sub-pixel 112 close to the third sub-pixel 113 toward its own center. Figure 7 As shown, the protrusion 1132 protrudes from the side of the light-emitting area of ​​the third sub-pixel 113 close to the second sub-pixel 112 toward the second sub-pixel 112, that is, it protrudes from the side of the light-emitting area of ​​the third sub-pixel 113 close to the second sub-pixel 112 toward the center away from itself. The specific shape and size of the recessed portion 1122 and the protrusion 1132 are not limited, and it is only necessary that the recessed portion 1122 can at least partially accommodate the protrusion 1132. In this way, the edge color fringing phenomenon during display can be optimized and the display graininess can be reduced. At the same time, the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 are mutually embedded, which is conducive to color mixing between the two and improves display uniformity.

[0094] More intuitively, the light-emitting area of ​​the second sub-pixel 112 having the recessed portion 1122 may be a U-shaped structure, and the light-emitting area of ​​the third sub-pixel 113 having the protruding portion 1132 may be a T-shaped structure, and the U-shaped structure surrounds at least part of the T-shaped structure.

[0095] It should be understood that in other embodiments, part or all of the light-emitting area of ​​the third sub-pixel 113 may be accommodated in the recessed portion 1122 of the second sub-pixel 112, so that at least part of the light-emitting area of ​​the third sub-pixel 113 is surrounded by the recessed portion 1122. In this case, the light-emitting area of ​​the third sub-pixel 113 may not have the so-called protruding portion 1132.

[0096] Please continue reading Figures 3 to 7In order to increase the area occupied by the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 in the first accommodating space 1110, in some embodiments, the light-emitting area of ​​the second sub-pixel 112 has at least one first side edge 1121 on the side away from the third sub-pixel 113, and the first side edge 1121 corresponds one-to-one to at least a portion of the first inner side edge 1112, and the first side edge 1121 and the corresponding first inner side edge 1112 are parallel to each other and spaced apart.

[0097] With such a configuration, the shape of the light-emitting area of ​​the second sub-pixel 112 is more adaptable to the shape of the first accommodating space 1110, so that the light-emitting area of ​​the second sub-pixel 112 can occupy a larger area in the first accommodating space 1110, thereby reducing the distance between the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the first sub-pixel 111, thereby improving the aperture ratio of the display panel 100.

[0098] Similarly, the light-emitting area of ​​the third sub-pixel 113 has at least one second side edge 1131 on the side away from the second sub-pixel 112, and the second side edge 1131 corresponds one-to-one to at least part of the first inner side edge 1112, and the second side edge 1131 and the corresponding first inner side edge 1112 are parallel to each other and spaced apart.

[0099] With such a configuration, the shape of the light-emitting area of ​​the third sub-pixel 113 is more adaptable to the shape of the first accommodating space 1110, so that the light-emitting area of ​​the third sub-pixel 113 can occupy a larger area in the first accommodating space 1110, thereby reducing the distance between the light-emitting area of ​​the third sub-pixel 113 and the light-emitting area of ​​the first sub-pixel 111, thereby improving the aperture ratio of the display panel 100.

[0105] Please combine Figure 1 Also see Figure 12 to Figure 13 For example, in another embodiment of the present application, the outer contour of the light-emitting area of ​​a sub-pixel 111 can be a regular hexagon, the light-emitting area of ​​the second sub-pixel 112 is a U-shaped structure, and its side line close to the first sub-pixel 111 is parallel to and spaced from the first inner side 1112 of the first sub-pixel, and the light-emitting area of ​​the third sub-pixel 113 is a T-shaped structure opposite to the light-emitting area of ​​the second sub-pixel 112, and its side line close to the first sub-pixel 111 is parallel to and spaced from the first inner side 1112 of the first sub-pixel, and one side of the T-shaped structure of the light-emitting area of ​​the third sub-pixel 113 is at least partially contained in the U-shaped area of ​​the U-shaped structure of the light-emitting area of ​​the second sub-pixel 112, so that the light-emitting area of ​​the second sub-pixel 112 surrounds at least part of the light-emitting area of ​​the third sub-pixel 113.

[0106] In other embodiments, the structure and arrangement of the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 may also be in other forms, so that the light-emitting area of ​​the second sub-pixel 112 surrounds at least part of the light-emitting area of ​​the third sub-pixel 113, which will not be repeated here.

[0107] Fig.14This is a schematic diagram of a pixel arrangement structure in a display panel 100 provided in yet another embodiment of the present application. Fig.15 This is a schematic structural diagram of a pixel group 110 in a pixel arrangement structure provided in yet another embodiment of the present application.

[0108] The light emitting area of ​​the second sub-pixel 112 surrounds at least a portion of the light emitting area of ​​the third sub-pixel 113. Figure 1 Also see Fig.14 and Fig.15 In some other embodiments, the light emitting area of ​​the second sub-pixel 112 is surrounded to form a second accommodating space 1120 , and the third sub-pixel 113 is disposed in the second accommodating space 1120 .

[0109] The light-emitting area of ​​the second sub-pixel 112 is surrounded to form the second accommodation space 1120, which means that the light-emitting area of ​​the second sub-pixel 112 is in a hollow ring shape, wherein the ring area is arranged around the hollow area, and the hollow area is the second accommodation space 1120, and the third sub-pixel 113 is arranged in the second accommodation space 1120. The specific shapes of the light-emitting area of ​​the second sub-pixel 112, the light-emitting area of ​​the third sub-pixel 113 and the first accommodation space 1110 can be regular or irregular, and are not limited here. The light-emitting areas of the light-emitting areas of the second sub-pixel 112 and the light-emitting areas of the third sub-pixel 113 are also not limited, but the cross-sectional area of ​​the second accommodation space 1120 should be larger than the light-emitting area of ​​the light-emitting area of ​​the third sub-pixel 113, so that the second accommodation space 1120 can accommodate the third sub-pixel 113. At this time, the light-emitting area of ​​the second sub-pixel 112 surrounds the entire light-emitting area of ​​the third sub-pixel 113 and wraps the light-emitting area of ​​the third sub-pixel 113 inside.

[0110] Fig.16 This is a schematic structural diagram of a second sub-pixel 112 in a pixel arrangement structure provided in yet another embodiment of the present application.

[0111] Please also read Figures 14 to 16 , the outer contour of the light emitting area of ​​the second sub-pixel 112 is a hexagon, and the second receiving space 1120 is also a hexagon. Furthermore, they can also be regular hexagons. On this basis, Fig.16As shown, the light-emitting area of ​​the second sub-pixel 112 has a plurality of second outer sides 1123 and a plurality of second inner sides 1124, the second inner sides 1124 correspond to the second outer sides 1123 one by one, and the second inner sides 1124 and the corresponding second outer sides 1123 are parallel to each other and are arranged at intervals. At the same time, the second outer sides 1123 correspond to the first inner sides 1112 one by one, and the second outer sides 1123 and the corresponding first inner sides 1112 are parallel to each other and are arranged at intervals. In other embodiments of the present application, the outer contour shape of the light-emitting area of ​​the second sub-pixel 112 can also be polygonal or circular or elliptical or quasi-circular, and can be exemplarily rectangular, pentagonal, hexagonal, octagonal, etc., and the shape of the second accommodating space 1120 can also be polygonal or circular or elliptical or quasi-circular, and can be exemplarily rectangular, pentagonal, hexagonal, octagonal, etc.

[0112] The outer contour of the light-emitting area of ​​the second sub-pixel 112 is a hexagon, and the plurality of second outer sides 1123 are the edges of its outer contour, and the plurality of second inner sides 1124 are the edges of its annular inner contour. The second inner sides 1124 correspond to the second outer sides 1123 one by one, and the second inner sides 1124 and the corresponding second outer sides 1123 are parallel to each other and arranged at intervals. At this time, the area enclosed between the plurality of second outer sides 1123 and the plurality of second inner sides 1124 is the light-emitting area of ​​the second sub-pixel 112, and the area enclosed inside the plurality of second inner sides 1124 is the second hexagonal accommodation space 1120. By enclosing the light-emitting area of ​​the second sub-pixel 112 to form the second accommodation space 1120, and the third sub-pixel 113 is arranged in the second accommodation space 1120, the edge color edge phenomenon during display can be further optimized, and the display graininess can be reduced.

[0113] On this basis, the second outer edge 1123 corresponds one-to-one with the first inner edge 1112 of the second sub-pixel 112, that is, the outer contour of the light-emitting area of ​​the second sub-pixel 112 and the annular inner contour of the light-emitting area of ​​the first sub-pixel 111 are arranged in a one-to-one correspondence. The shape of the light-emitting area of ​​the second sub-pixel 112 and the second accommodating space 1120 enclosed by it is more regular, which is convenient for processing and manufacturing, and is beneficial to reducing the distance between the second sub-pixel 112 and the first sub-pixel 111, thereby improving the aperture ratio of the display panel 100.

[0114] Fig.17 This is a schematic structural diagram of a third sub-pixel 113 in a pixel arrangement structure provided in yet another embodiment of the present application.

[0115] The specific shape of the light-emitting area of ​​the third sub-pixel 113 can be a regular shape or an irregular shape. In some specific embodiments, the shape of the light-emitting area of ​​the third sub-pixel 113 is a polygon. Further, the shape of the light-emitting area of ​​the third sub-pixel 113 can be a hexagon. On this basis, Fig.17 As shown, the light-emitting area of ​​the third sub-pixel 113 has a plurality of third side edges 1133, and the third side edges 1133 correspond to the second inner side edges 1124 one by one, and the third side edges 1133 and the corresponding second inner side edges 1124 are parallel to each other and arranged at intervals. In other embodiments of the present application, the shape of the light-emitting area of ​​the third sub-pixel 113 can also be polygonal, circular, elliptical or quasi-circular, and can be, for example, rectangular, pentagonal, hexagonal, octagonal, etc.

[0116] That is, the outer contour of the light-emitting area of ​​the third sub-pixel 113 is a hexagon, and the multiple third side edges 1133 are the edge lines of its outer contour, and the third side edges 1133 correspond one-to-one with the second inner side edges 1124 of the second sub-pixel 112, that is, the edge lines of the outer contour of the light-emitting area of ​​the third sub-pixel 113 and the edge lines of the annular inner contour of the light-emitting area of ​​the second sub-pixel 112 are arranged one-to-one correspondingly, which is beneficial to reducing the distance between the third sub-pixel 113 and the second sub-pixel 112, thereby further improving the aperture ratio of the display panel 100.

[0117] In some of the above embodiments, the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112, and the light-emitting area of ​​the third sub-pixel 113 are all axisymmetric patterns, and they all have a symmetry axis along the first direction x or along the second direction y. Figure 3 , Fig. 9 and Fig.13 In the embodiment shown, the light-emitting area of ​​the first sub-pixel 111 has a plurality of symmetric axes, including a symmetric axis arranged along the first direction x and a symmetric axis arranged along the second direction y. The light-emitting areas of the second sub-pixel 112 and the light-emitting areas of the third sub-pixel 113 both have symmetric axes arranged along the first direction x. Fig.15 In the embodiment shown, the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112, and the light-emitting area of ​​the third sub-pixel 113 all have multiple symmetry axes, including a symmetry axis arranged along the first direction x and a symmetry axis arranged along the second direction y. Therefore, the symmetry axis of the light-emitting area of ​​the second sub-pixel 112 can be collinear with the symmetry axis of the light-emitting area of ​​the third sub-pixel 113. Figure 3 and Figure 7 In the embodiment shown, the symmetry axis is arranged along the first direction x. Fig.12 In the illustrated embodiment, the symmetry axis may be arranged along the first direction x or along the second direction y, so that the light emitting area of ​​the second sub-pixel 112 and the light emitting area of ​​the third sub-pixel 113 are arranged more regularly.

[0118] On this basis, since in any embodiment, the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112, and the light-emitting area of ​​the third sub-pixel 113 all have a symmetry axis arranged along the first direction x, further, the symmetry axis of the light-emitting area of ​​the first sub-pixel 111, the symmetry axis of the light-emitting area of ​​the second sub-pixel 112, and the symmetry axis of the light-emitting area of ​​the third sub-pixel 113 can be collinear. Figure 3 , Fig. 9 and Fig.13 In the embodiment shown, the symmetry axis is arranged along the first direction x. Fig.15 In the embodiment shown, the symmetry axis can be arranged along the first direction x or the second direction y. This design makes the arrangement of each sub-pixel in the pixel group 110 more uniform, which is conducive to improving the overall display uniformity and ensuring the linearity of the display.

[0119] In order to further improve the uniformity of the arrangement of sub-pixels in the pixel arrangement structure, in some embodiments, the line connecting the corresponding position points of the light-emitting areas of the same-color sub-pixels located in the same row is parallel to the first direction x; the line connecting the corresponding vertices of the light-emitting areas of the same-color sub-pixels located in the same column is parallel to the second direction y.

[0120] The corresponding position points of the light-emitting areas of the same-color sub-pixels refer to the two endpoints or vertices or internal points of the light-emitting areas of the two same-color sub-pixels at the corresponding same positions, that is, in the entire pixel arrangement structure, the corresponding position points of the light-emitting areas of the same-color sub-pixels in the same row are located on the same straight line, and the straight line is arranged along the first direction x. In other words, the corresponding position points of the light-emitting areas of the first sub-pixels 111 in the same row are located on the same straight line, the corresponding position points of the light-emitting areas of the second sub-pixels 112 in the same row are located on the same straight line, and the corresponding position points of the light-emitting areas of the third sub-pixels 113 in the same row are located on the same straight line. In addition, the corresponding position points of the light-emitting areas of the same-color sub-pixels in the same column are located on the same straight line, and the straight line is arranged along the second direction y, that is, the corresponding position points of the light-emitting areas of the first sub-pixels 111 in the same column are located on the same straight line, the corresponding position points of the light-emitting areas of the second sub-pixels 112 in the same column are located on the same straight line, and the corresponding position points of the light-emitting areas of the third sub-pixels 113 in the same column are located on the same straight line. This design makes the arrangement of the pixel group 110 more uniform, and the sub-pixels of the same color are arranged uniformly and regularly, which is beneficial to improving the overall display uniformity.

[0121] As described above, multiple pixel groups 110 can be arranged in an array by staggering along a first direction x and a second direction y that are perpendicular to each other. Specifically, in some embodiments, along the first direction x, the symmetry axis of the light-emitting area of ​​the first sub-pixel 111 in any pixel group 110 passes between the light-emitting areas of the first sub-pixels 111 in two adjacent pixel groups 110 in adjacent columns.

[0122] Depending on the different outer contour shapes of the light-emitting area of ​​the first sub-pixel 111, the arrangement of the plurality of pixel groups 110 in the pixel arrangement structure is also different. Figure 2 As shown, the outer contour of the light-emitting area of ​​the first sub-pixel 111 is a rectangle. At this time, along the first direction x, the symmetric axis of the light-emitting area of ​​the first sub-pixel 111 in any pixel group 110 is collinear with the symmetric axis of the light-emitting area of ​​the first sub-pixel 111 in the corresponding pixel group 110 in the adjacent column. At the same time, along the second direction y, the symmetric axis of the light-emitting area of ​​the first sub-pixel 111 in any pixel group 110 is collinear with the symmetric axis of the light-emitting area of ​​the first sub-pixel 111 in the corresponding pixel group 110 in the adjacent row. In other words, the plurality of pixel groups 110 are arranged in a rectangular array of multiple rows and columns, which is conducive to improving the arrangement density of the pixel groups 110 and improving the aperture ratio of the display panel 100.

[0123] like Figure 8 , Fig.10 , Fig.12 and Fig.14 As shown, the outer contour of the light-emitting area of ​​the first sub-pixel 111 is a regular hexagon. At this time, in any two adjacent columns of pixel groups 110, the light-emitting area of ​​the first sub-pixel 111 in any pixel group 110 has a symmetry axis arranged along the first direction x, and the symmetry axis passes between the light-emitting areas of the first sub-pixels 111 in two adjacent pixel groups 110 in another column of pixel groups 110, but does not pass through the light-emitting areas thereof. In other words, any two adjacent columns of pixel groups 110 are arranged in an interlaced manner, and such a design improves the aperture ratio of the display panel 100.

[0124] Please continue reading Figure 1 In the display panel 100 of the present application, the display panel 100 may further include a substrate 120 , and a plurality of pixel groups 110 in the pixel arrangement structure are disposed on the substrate 120 .

[0125] Specifically, the substrate 120 is used to support and carry other film layers in the display panel 100. For example, the substrate 120 can be made of materials such as glass and polyimide (PI). The display panel 100 provided in the embodiment of the present application can be an organic light-emitting display panel 100. The sub-pixel includes at least an anode and a cathode, and a light-emitting functional layer 150 located between the anode and the cathode. The driving circuit applies a voltage between the anode and the cathode to stimulate carrier migration and act on the light-emitting functional layer 150 to emit light. The light-emitting functional layer 150 of the sub-pixel may include a multi-layer structure. For example, each light-emitting functional layer 150 includes a stacked hole injection part, a hole transport part, a light-emitting part, an electron transport part, an electron injection part, etc. (not shown in the figure).

[0126] Fig.18 This is a cross-sectional view of the overall structure of a display panel 100 provided in another embodiment of the present application.

[0127] like Fig.18 As shown, in other embodiments, the display panel 100 may further include an isolation structure 130, and the isolation structure 130 is located between at least some adjacent sub-pixels, that is, in the pixel arrangement structure of the display panel 100, an isolation structure 130 is provided between some two adjacent sub-pixels, or an isolation structure 130 is provided between every two adjacent sub-pixels. Due to the existence of the isolation structure 130, the sub-pixels located on both sides thereof are separated, specifically, the light-emitting functional layer 150 and the first electrode 160 in the sub-pixel are separated by the isolation structure 130, wherein the first electrode 160 may be an anode layer or a cathode layer, and the first electrode 160 is provided on the light-emitting functional layer 150, and the light-emitting functional layer 150 is covered by the first electrode 160 and does not contact the isolation structure 130.

[0128] It should be noted that the isolation structure 130 is only Fig.18 The isolation structure 130 is shown in the overall structure of the display panel 100, while in the structural schematic diagrams of other pixel arrangement structures and the structural schematic diagram of the pixel group 110, the isolation structure 130 is not shown, but it does not mean that the isolation structure 130 does not exist. The isolation structure 130 can also be arranged between two adjacent sub-pixels, or the isolation structure 130 is arranged between every two adjacent sub-pixels.

[0129] During the manufacturing process of the display panel 100 with the isolation structure 130, the formation of its sub-pixels does not need to be carried out by evaporation using a mask plate. The isolation structure 130 can replace the function of the mask plate. With the help of the separation of the isolation structure 130, the distance between two adjacent sub-pixels or pixel groups 110 can be shortened, making the arrangement between sub-pixels or pixel groups 110 more compact, achieving a higher PPI, and thus improving the manufacturing accuracy of the sub-pixels.

[0130] The isolation structure 130 may be an integrated structure, or may include a relatively independent isolation body 131 and a blocking portion 132, wherein the isolation body 131 is located on the substrate 120, and the blocking portion 132 is located on the side of the isolation body 131 away from the substrate 120, and the area covered by the orthographic projection of the blocking portion 132 on the substrate 120 is relatively large, while the area covered by the orthographic projection of the isolation body 131 on the substrate 120 is relatively small, so that the orthographic projection of the blocking portion 132 on the substrate 120 can cover the orthographic projection of the isolation body 131 on the substrate 120. The cross-sectional shapes of the isolation body 131 and the blocking portion 132 may be regular shapes, such as rectangles, triangles, etc., or irregular shapes.

[0131] Fig.19 This is a cross-sectional view of the overall structure of a display panel 100 provided in yet another embodiment of the present application.

[0132] The substrate 120 can be kept flat as a whole, and the isolation structure 130 is protrudingly arranged on the flat substrate 120. Fig.19 As shown, the substrate 120 can also be a non-flat structure, that is, a first groove 121 can be further provided on the substrate 120. In this case, the isolation structure 130 can be provided in the first groove 121. In this way, the space occupied by the isolation structure 130 in a direction perpendicular to the surface of the substrate 120 can be reduced, thereby reducing the overall space occupied by the display panel 100, making it thinner and lighter. In addition, the light blocking angle of the isolation structure 130 is smaller, thereby increasing the viewing angle of the display panel 100.

[0133] Please continue reading Fig.19 Specifically, the first groove 121 of the substrate 120 has a bottom wall 1211 and side walls 1212 respectively connected to both sides of the bottom wall 1211 , and the isolation structure 130 is disposed on the bottom wall 1211 .

[0134] Furthermore, a surface of the isolation structure 130 on one side facing away from the substrate 120 protrudes above the plane where the substrate 120 is located, that is, in a direction perpendicular to the surface of the substrate 120, the height of the isolation structure 130 is greater than the depth of the depression of the first groove 121. In this way, the isolation structure 130 located in the first groove 121 can still play the role of separating two adjacent sub-pixels, thereby facilitating the production and molding of the display panel 100.

[0135] Fig. 20 This is a cross-sectional view of the overall structure of a display panel 100 provided in yet another embodiment of the present application.

[0136] See also Fig. 20The display panel 100 may further include a pixel defining layer 140 , wherein the pixel defining layer 140 defines a plurality of pixel openings 141 spaced apart from each other, and the sub-pixels are at least partially located within the pixel openings 141 .

[0137] The pixel defining layer 140 of the display panel 100 can be arranged in the same layer as the first electrode 114 of the sub-pixel, and the first electrode 114 of the sub-pixel is at least partially exposed by the pixel opening 141 to facilitate the normal light emission of the sub-pixel. The light-emitting function layer 115 of the sub-pixel is arranged in the pixel opening 141 to avoid cross-color or interference between adjacent sub-pixels. Therefore, in some embodiments, the pixel edge of the sub-pixel is the boundary of the pixel opening 141 of the pixel defining layer 140, and the area of ​​the pixel opening 141 is the light-emitting area of ​​the sub-pixel.

[0138] In order to isolate two adjacent sub-pixels, in some embodiments, a second groove 142 is provided on the pixel defining layer 140, and the second groove 142 is located between at least some of the adjacent pixel openings 141, that is, in the pixel arrangement structure of the display panel 100, a second groove 142 is provided between some of the adjacent two sub-pixels, or a second groove 142 is provided between every two adjacent sub-pixels. Due to the chamfered structure of the second groove 142, the light-emitting functional layer 115 can be disconnected, so that the sub-pixels located on both sides of the second groove 142 are separated. The second groove 142 can penetrate the pixel defining layer 140, and the cross-sectional shape of the second groove 142 can be trapezoidal.

[0139] It should be noted that in other embodiments, due to the chamfered structure of the second groove 142, the light-emitting functional layer 115 and the second electrode 116 can be disconnected by adjusting the groove depth of the second groove 142, so that the sub-pixels located on both sides of the second groove 142 are separated.

[0140] Fig.21 This is a cross-sectional view of the overall structure of a display panel 100 provided in yet another embodiment of the present application.

[0141] In some other embodiments, the display panel 100 includes both the isolation structure 130 and the pixel defining layer 140. Fig.21As shown, the isolation structure 130 may be disposed on the pixel defining layer 140, and the sub-pixel is at least partially located in the pixel opening 141. At this time, the isolation structure 130 may include a conductive material, specifically, at least a portion of the isolation body 131 in the isolation structure 130 may be made of a conductive material, such as metal, or at least a portion of the blocking portion 132 in the isolation structure 130 may be made of a conductive material, such as metal, and the second electrode 116 is overlapped with the isolation structure 130. In this way, the plurality of second electrodes 116 can be electrically connected with the aid of the isolation structure 130 to form a whole-surface electrode, thereby reducing its resistance and improving the performance of the display panel 100.

[0142] The isolation structure 130 can be an integrated structure, and the isolation structure 130 can also include relatively independent isolation bodies 131, blocking parts 132 and base parts 133, wherein the base parts 133 are located on the side of the isolation body 131 close to the substrate 120, that is, in the isolation structure, the base parts 133, the isolation body 131 and the blocking parts 132 are stacked on the substrate 120 in sequence, wherein the area covered by the orthographic projection of the base parts 133 on the substrate 120 is larger, while the area covered by the orthographic projection of the isolation body 131 on the substrate 120 is relatively smaller, and the orthographic projection of the isolation body 131 on the substrate 120 is located within the orthographic projection of the base parts 133 on the substrate 120, so that the isolation structure 130 as a whole is an "I"-shaped structure with large ends of the base parts 133 and the blocking parts 132 and a small middle part of the isolation body 131.

[0143] In other embodiments, the orthographic projection of the second electrode 116 on the substrate 120 and the orthographic projection of the blocking portion 132 on the substrate 120 can be spaced apart from each other, that is, the second electrode 116 and the isolation structure 130 are spaced apart from each other and do not overlap each other. In this case, the second electrode 116 can be electrically connected to the signal line or data line through conventional means such as metal wiring connection. In this case, the isolation structure 130 has a better isolation effect on the sub-pixels and is more convenient to manufacture.

[0144] Fig. 22 A schematic diagram of the structure of a pixel group in a display panel provided by one embodiment of the present application.

[0145] Please combine Figure 1 Also see Fig. 22The embodiment of the present application also provides a display panel 100, which includes a substrate 120 and a plurality of pixel groups 110. The plurality of pixel groups 110 are arranged on the substrate 120. The pixel group 110 includes at least one first sub-pixel 111, at least one second sub-pixel 112 and at least one third sub-pixel 113. The first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 respectively include an electrode portion and a light-emitting functional layer 115. The electrode portion of the first sub-pixel 111 is arranged to form a third accommodating space 1114, and the electrode portion of the second sub-pixel 112 and the electrode portion of the third sub-pixel 113 are arranged in the third accommodating space 1114.

[0146] In any of the above embodiments, the light-emitting area of ​​the first sub-pixel 111 is surrounded to form the first accommodation space 1110, and the second sub-pixel 112 and the third sub-pixel 113 are arranged in the first accommodation space 1110. Different from the above embodiments, in this embodiment, the electrode portion of the first sub-pixel 111 is surrounded to form the third accommodation space 1114, and the electrode portion of the second sub-pixel 112 and the electrode portion of the third sub-pixel 113 are arranged in the third accommodation space 1114. In this way, the edge color fringing phenomenon of the display panel 100 during display can also be optimized, the display graininess can be reduced, the white light ratio can be optimized, and the display effect can be improved.

[0147] It should be noted that the electrode portion of the first sub-pixel 111 includes a first electrode 114 and a second electrode 116, the first electrode 114, the light-emitting functional layer 115, and the second electrode 116 are stacked in sequence, and the first electrode 114 and / or the second electrode 116 are surrounded to form a third accommodation space 1114. That is, the third accommodation space 1114 surrounded by the electrode portion of the first sub-pixel 111 can be formed by the first electrode 114 of the first sub-pixel 111, can be formed by the second electrode 116 of the first sub-pixel 111, or can be formed by the first electrode 114 and the second electrode 116 of the first sub-pixel 111.

[0148] In the above embodiment, the light-emitting area of ​​the second sub-pixel 112 surrounds at least part of the light-emitting area of ​​the third sub-pixel 113. Similarly, the electrode portion of the second sub-pixel 112 surrounds at least part of the electrode portion of the third sub-pixel 113. In this way, the edge color fringing phenomenon during display of the display panel 100 can be optimized, and the display graininess can be reduced. At the same time, the electrode portion of the second sub-pixel 112 and the electrode portion of the third sub-pixel 113 are mutually embedded, which is conducive to the mutual mixing of colors when the two emit light, thereby improving the display uniformity.

[0149] In some other embodiments, the light emitting area of ​​the second sub-pixel 112 is surrounded to form a second accommodation space 1120, and the third sub-pixel 113 is disposed in the second accommodation space 1120. Similarly, the electrode portion of the second sub-pixel 112 is surrounded to form a fourth accommodation space 1125, and the electrode portion of the third sub-pixel 113 is disposed in the fourth accommodation space 1125. In this way, the edge color fringing phenomenon of the display panel 100 during display can be further optimized, and the display graininess can be reduced.

[0150] Fig.23 A schematic structural diagram of an isolation structure 130 in a display panel 100 provided in one embodiment of the present application.

[0151] Please combine Figure 1 Also see Fig.23 The embodiment of the present application further provides a display panel 100, which includes a substrate 120, a plurality of pixel groups 110 and an isolation structure 130. The plurality of pixel groups 110 are disposed on the substrate 120. The pixel groups 110 include at least one first sub-pixel 111, at least one second sub-pixel 112 and at least one third sub-pixel 113. The isolation structure 130 is disposed on the substrate 120. The isolation structure 130 encloses a first opening 134 for accommodating the first sub-pixel 111, a second opening 135 for accommodating the second sub-pixel 112, and a third opening 136 for accommodating the third sub-pixel 113. The second opening 135 and the third opening 136 are disposed in the first opening 134.

[0152] In the display panel 100, the isolation structure 130 is located between at least a portion of adjacent sub-pixels. Fig.21 In the illustrated embodiment, exemplarily, the isolation structure 130 is disposed between two adjacent pixel groups 110 on the substrate 120, and also between two adjacent sub-pixels within the pixel group 110, and the isolation structure 130 encloses a first opening 134 for accommodating the first sub-pixel 111, a second opening 135 for accommodating the second sub-pixel 112, and a third opening 136 for accommodating the third sub-pixel 113.

[0153] The shapes of the first opening 134, the second opening 135 and the third opening 136 may be regular shapes, such as polygonal, circular, elliptical or quasi-circular, etc., or irregular shapes. The specific opening sizes thereof are not limited. The shape and size of the first opening 134 are adapted to the shape and size of the first sub-pixel 111, the shape and size of the second opening 135 are adapted to the shape and size of the second sub-pixel 112, and the shape and size of the third opening 136 are adapted to the shape and size of the third sub-pixel 113. Therefore, the different implementations of the first opening 134, the second opening 135 and the third opening 136 may refer to the description in other embodiments above, and will not be repeated here.

[0154] It should be noted that although Fig.23 In the cross section shown, the isolation structures 130 inside and outside the first opening 134, the second opening 135 and the third opening 136 appear to be isolated from each other, but in the actual structure of the display panel 100, the isolation structures 130 in various locations can be electrically connected to each other by means of wiring provided in the frame area passing through vias on the film layer structure, that is, in the display panel 100, the isolation structures 130 as a whole are a full-surface mesh structure connected to each other.

[0155] In this embodiment, by changing the relative positional relationship among the first opening 134, the second opening 135 and the third opening 136, the relative positional relationship among the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 can be changed. Therefore, in order to improve the display effect of the display panel 100, in some embodiments, the second opening 135 and the third opening 136 are arranged in the first opening 134. With such a design, after each sub-pixel is accommodated in the opening corresponding to it, the second sub-pixel 112 and the third sub-pixel 113 can be arranged in the light-emitting area of ​​the first sub-pixel 111, which can optimize the edge color fringing phenomenon during display, reduce the display graininess, optimize the white light ratio, and improve the display effect.

[0156] In some embodiments, the second opening 135 can be made to surround at least a portion of the third opening 136, so that the second sub-pixel 112 surrounds at least a portion of the third sub-pixel 113. In this way, the edge color fringing phenomenon of the display panel 100 during display can be optimized and the display graininess can be reduced. At the same time, the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 are mutually interlocked, which is beneficial to the mutual mixing of colors when the two emit light, thereby improving the display uniformity.

[0157] In other embodiments, the third opening 136 can be disposed in the second opening 135 so that the light-emitting area of ​​the third sub-pixel 113 is disposed in the light-emitting area of ​​the second sub-pixel 112. In this way, the edge color fringing phenomenon of the display panel 100 during display can be further optimized and the display graininess can be reduced.

[0158] Furthermore, in the display panel 100 of the present embodiment, the isolation structure 130 is configured to enclose a first opening 134 for accommodating the first sub-pixel 111, a second opening 135 for accommodating the second sub-pixel 112, and a third opening 136 for accommodating the third sub-pixel 113, so that the processing and manufacturing of the display panel 100 does not require the use of a mask, thereby improving the manufacturing accuracy, reducing the manufacturing cost, optimizing the edge color fringing phenomenon during display, reducing the display graininess, facilitating color mixing during display, and improving display uniformity.

[0159] Fig.24This is a schematic diagram of the overall structure of a display device 10 provided in one embodiment of the present application.

[0160] Please combine Figure 1 Also see Fig.24 The embodiment of the present application further provides a display device 10, which includes a display panel 100 as in any of the above embodiments.

[0161] The display panel 100 disclosed in any of the above embodiments of the present application is applied to a display device 10 to provide a screen display function, and the display device 10 can be any product or component with a display function, including but not limited to a mobile phone, a tablet computer, a laptop computer, an e-reader, a wearable device, a remote control, a television, a desktop computer, a vehicle-mounted device, etc. The display device 10 of the embodiment of the present application is configured such that the light-emitting area of ​​the first sub-pixel 111 in the display panel 100 is surrounded to form a first accommodation space 1110, the second sub-pixel 112 and the third sub-pixel 113 are arranged in the first accommodation space 1110, and the light-emitting area of ​​the second sub-pixel 112 surrounds at least part of the light-emitting area of ​​the third sub-pixel 113, so as to optimize the edge color fringing phenomenon during display, reduce the display graininess, optimize the white light ratio, and improve the display effect.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
