[0003] However, the color fringing phenomenon of the above display panel during display is relatively serious. Summary of the invention

DETAILED DESCRIPTION

[0071] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings.

[0072] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0074] 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 emission 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.

[0075] See also Figure 1, the pixel arrangement structure 1 is a first pixel arrangement structure, each pixel 10 includes a red sub-pixel 11, a green sub-pixel 12 and a blue sub-pixel 13, the red sub-pixel 11 and the green sub-pixel 12 are located on the same side of the blue sub-pixel 13, a plurality of pixels 10 are arranged in a plurality of rows and columns, two pixels 10 adjacent to each other along the column direction include a first pixel and a second pixel, in the first pixel, the red sub-pixel 11 and the green sub-pixel 12 are located on one side of the blue sub-pixel 13 along the row direction, and in the second pixel, the red sub-pixel 11 and the green sub-pixel 12 are located on the other side of the blue sub-pixel 13 along the row direction. See Figure 2 , the pixel arrangement structure 1 is the second pixel arrangement structure, each pixel 10 includes a red sub-pixel 11, a green sub-pixel 12 and a blue sub-pixel 13, the red sub-pixel 11 and the green sub-pixel 12 are located on the same side of the blue sub-pixel 13, and the multiple pixels 10 are arranged in multiple rows and columns, and the red sub-pixel 11 and the green sub-pixel 12 in each pixel 10 are located on the same side of the blue sub-pixel 13 along the row direction. The above two pixel arrangement structures can improve the aperture ratio. However, the display is often accompanied by more obvious color fringing.

[0076] However, the color fringing phenomenon of the above two pixel arrangement structures during display is relatively serious, thereby affecting the display effect of the pixel arrangement structure, the display panel and the display device.

[0077] To solve the above problems, an embodiment of the present application provides a pixel arrangement structure, a display panel and a display device, wherein each pixel unit includes a first sub-pixel group and a second sub-pixel group arranged along a first direction, so that the edges of the pixel arrangement structure on both sides along the first direction can be formed by the first sub-pixel group and the second sub-pixel group. The plurality of sub-pixels of the first sub-pixel group include the first sub-pixel, the second sub-pixel and the third sub-pixel with different luminous colors and arranged along the second direction, so that the edge formed by the first sub-pixel group presents the first sub-pixel, the second sub-pixel and the third sub-pixel arranged in sequence, avoiding the situation that the sub-pixels of the same color are concentrated on the edge formed by the first sub-pixel group, thereby improving the color edge phenomenon of the edge formed by the first sub-pixel group. In addition, the plurality of sub-pixels of the second sub-pixel group include the fourth sub-pixel and the white sub-pixel with different luminous colors, and the second sub-pixel and the fourth sub-pixel have the same luminous color, so that the edge formed by the second sub-pixel group presents the fourth sub-pixel and the white sub-pixel arranged in sequence, and the white sub-pixel can weaken the color edge phenomenon brought by the fourth sub-pixel, thereby improving the color edge phenomenon of the edge formed by the second sub-pixel group. Therefore, the color edge phenomenon of the edge on both sides of the pixel arrangement structure along the first direction can be improved, thereby improving the display effect of the pixel arrangement structure, the display panel and the display device. Secondly, by adding white sub-pixels to the pixels, the brightness of the display panel can be improved, or, when the display brightness remains unchanged, the power consumption of the display panel can be reduced.

[0078] For a better understanding, some explanations are given before going into detail:

[0079] 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.

[0080] 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 (i.e., red sub-pixels), 1920 G sub-pixels (i.e., green sub-pixels), and 1920 B sub-pixels (i.e., blue sub-pixels) in the other direction.

[0081] 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.

[0082] 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.

[0083] The display device provided in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0084] The present application provides a display device, which includes a display panel. The display device can be an electronic paper, a mobile phone, a tablet computer, a television, a display, a laptop, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camera, a game console, a clock, a calculator, a television monitor, a computer monitor, a car display (e.g., an odometer display, etc.), a cockpit controller and / or display, a display of a camera view (e.g., a display of a rear-view camera in a vehicle), an electronic billboard or sign, a projector, and other mobile or fixed terminals.

[0085] Exemplarily, the display panel may be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light emitting diode (LED) display panel, a quantum dot light emitting diode (QLED) display panel, a mini light emitting diode (Mini LED) display panel, a micro light emitting diode (Micro LED) display panel, or a liquid crystal (LCD) display panel. The embodiments of the present application are described by taking an OLED display panel as an example.

[0086] For example, the display panel may be a medium-sized display panel for use in vehicles, notebook computers, flat panel displays, etc. The PPI of the medium-sized display panel may be less than or equal to 300. Figure 1 ), the display effect can be significantly improved.

[0087] The display panel provided in the embodiments of the present application is described below.

[0088] In some embodiments, the display panel may include a substrate, and the substrate may provide support for the remaining structural layers that are subsequently arranged. In some examples, the substrate may be a rigid substrate, for example, the material of the substrate may be glass. In some other examples, the substrate may be a flexible substrate, and the material of the substrate may include at least one of polyimide (PI), polyethylene terephthalate, polyethylene naphthalate, polyethylene, polyacrylate, polyetherimide, polycarbonate, polyarylate, and polyethersulfone.

[0089] In some embodiments, the display panel may include a pixel arrangement structure 100 ( Figure 3 ), the pixel arrangement structure 100 can be arranged on a substrate.

[0090] In some embodiments, see Figure 3, the display panel may have a first direction X, a second direction Y and a third direction, and the first direction X, the second direction Y and the third direction are all different. The first direction X and the second direction Y may be any two different directions parallel to the display panel, and the third direction may be any direction intersecting with a plane parallel to the display panel. For example, the first direction X, the second direction Y and the third direction may be perpendicular to each other. Exemplarily, the first direction X may be the width direction of the display panel, the second direction Y may be the length direction of the display panel, and the third direction may be the thickness direction of the display panel. The length, width and thickness in the embodiments of the present application are merely for the convenience of description and do not imply any limitation on the size. For example, the width may be greater than, equal to or less than the length.

[0091] The pixel arrangement structure 100 provided in an embodiment of the present application is described below.

[0092] In some embodiments, see Figure 3 and Figure 8 , the pixel arrangement structure 100 may include a plurality of pixel units 110, and the plurality of pixel units 110 may be located on a substrate. For example, the plurality of pixel units 110 may be arranged in rows along a first direction X, and in columns along a second direction Y. The plurality of pixel units 110 arranged along the first direction X may form a pixel unit row 100a, and there may be a plurality of pixel unit rows 100a, and the plurality of pixel unit rows 100a may be arranged along the second direction Y. For example, the plurality of pixel units 110 may be arranged in an array, so as to alleviate the jaggedness and discontinuity of the image of the display panel.

[0093] For example, see Figure 3 , two adjacent pixel unit rows 100a may include a first pixel unit row 101a and a second pixel unit row 102a. In some examples, the pixel units 110 of the first pixel unit row 101a and the pixel units 110 of the second pixel unit row 102a are arranged relative to each other along the second direction Y. In other examples, the pixel units 110 of the first pixel unit row 101a and the pixel units 110 of the second pixel unit row 102a are arranged in a staggered manner along the second direction Y, for example, the pixel units 110 of the first pixel unit row 101a and the area between the two adjacent pixel units 110 of the second pixel unit row 102a are arranged relative to each other. The embodiment of the present application is described by taking the pixel units 110 of the first pixel unit row 101a and the pixel units 110 of the second pixel unit row 102a as an example in which the pixel units 110 of the first pixel unit row 101a and the pixel units 110 of the second pixel unit row 102a are arranged relative to each other along the second direction Y.

[0094] In some embodiments, see Figure 3 , Figure 3Four pixel units 110 are shown in the figure, and two pixel units 110 arranged along the first direction X form a pixel unit row 100a, and two pixel unit rows 100a are shown in total. Each pixel unit 110 may include a first sub-pixel group 120a and a second sub-pixel group 120b arranged along the first direction X, so that the edges of the pixel arrangement structure 100 on both sides along the first direction X are formed by the first sub-pixel group 120a and the second sub-pixel group 120b. Among them, the first sub-pixel group 120a and the second sub-pixel group 120b may each include a plurality of sub-pixels 120 arranged along the second direction Y. The multiple sub-pixels 120 of the first sub-pixel group 120a may include a first sub-pixel 121, a second sub-pixel 122 and a third sub-pixel 123 with different luminous colors, so that the edge formed by the first sub-pixel group 120a presents the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 arranged in sequence, avoiding the situation where the same-color sub-pixels 120 are concentrated on the edge formed by the first sub-pixel group 120a, thereby improving the color edge phenomenon of the edge formed by the first sub-pixel group 120a. The plurality of sub-pixels 120 of the second sub-pixel group 120b may include a fourth sub-pixel 124 with different luminous colors and a white sub-pixel 125 (luminous color is white), so that the edge formed by the second sub-pixel group 120b presents the fourth sub-pixel 124 and the white sub-pixel 125 arranged in sequence, and the white sub-pixel 125 can weaken the color edge phenomenon brought by the fourth sub-pixel 124, thereby improving the color edge phenomenon of the edge formed by the second sub-pixel group 120b, and therefore, the color edge phenomenon of the edge along both sides of the first direction X of the pixel arrangement structure 100 can be improved, thereby improving the display effect of the pixel arrangement structure 100, the display panel and the display device. Secondly, by adding the white sub-pixel 125 in the pixel unit 110, the brightness of the display panel can be improved, or, when the display brightness remains unchanged, the power consumption of the display panel can be reduced.

[0095] For example, the edge of the pixel arrangement structure 100 along one side of the first direction X may be formed by a plurality of first sub-pixel groups 120a, and the edge of the pixel arrangement structure 100 along the other side of the first direction X may be formed by a plurality of second sub-pixel groups 120b. Alternatively, the edge of the pixel arrangement structure 100 along any side of the first direction X may be formed by a plurality of first sub-pixel groups 120a and a plurality of second sub-pixel groups 120b at the same time. This embodiment of the present application is not limited to this.

[0096] Exemplarily, the luminous colors of the second sub-pixel 122 and the fourth sub-pixel 124 can be the same. Taking the second sub-pixel 122 and the fourth sub-pixel 124 as green sub-pixels as an example, the green sub-pixel can be divided into two sub-pixels 120 with smaller areas, that is, the setting area of ​​the second sub-pixel 122 and the fourth sub-pixel 124 can be smaller, and the setting flexibility of the second sub-pixel 122 and the fourth sub-pixel 124 can be improved, which is conducive to reducing the distance between the second sub-pixel 122 and the fourth sub-pixel 124 and other adjacent sub-pixels 120, so that each sub-pixel 120 in the same pixel unit 110 is compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio and the luminous area. For example, the second sub-pixel 122 and the fourth sub-pixel 124 in the same pixel unit 110 can be electrically connected to the same pixel driving circuit to achieve common driving. Since the human eye is more sensitive to green, the green sub-pixel will have a greater impact on the fineness of the display. The green sub-pixel in the same pixel unit 110 is set to two, so that when displaying text or fine content, the display density is increased, and the displayed content will be clearer.

[0097] Among them, the pixel unit 110 refers to: the smallest repeating unit repeatedly arranged in the display panel. The first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 can be one of a red sub-pixel (emitting red color), a blue sub-pixel (emitting blue color) and a green sub-pixel (emitting green color). Of course, in some other embodiments, the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 can also be a sub-pixel 120 that emits light of other colors besides red, green and blue, for example, a white sub-pixel or a yellow sub-pixel, which is not limited in the embodiments of the present application. The sub-pixel 120 is characterized as the smallest unit for emitting light. The embodiments of the present application are described by taking the first sub-pixel 121 as a red sub-pixel, the second sub-pixel 122 and the fourth sub-pixel 124 as green sub-pixels, and the third sub-pixel 123 as a blue sub-pixel as an example.

[0098] In some embodiments, a plurality of first sub-pixel groups 120a are arranged along the second direction Y to form first pixel columns, a plurality of second sub-pixel groups 120b are arranged along the second direction Y to form second pixel columns, and the first pixel columns and the second pixel columns are alternately arranged along the first direction X.

[0099] Exemplarily, in the same first sub-pixel group 120 a , the first sub-pixel 121 , the second sub-pixel 122 , and the third sub-pixel 123 are arranged along the second direction.

[0100] Exemplarily, in the same second sub-pixel group 120 b , the fourth sub-pixel 124 and the white sub-pixel 125 are arranged along the second direction.

[0101] The following describes the arrangement of multiple sub-pixels 120 in the same pixel unit 110 in the embodiment of the present application.

[0102] In some embodiments, see Figure 3 In the same first sub-pixel group 120a, the second sub-pixel 122 can be located between the first sub-pixel 121 and the third sub-pixel 123. In this way, the green sub-pixel can be set between the red sub-pixel and the blue sub-pixel, which can better alleviate the display pink color edge problem caused by the edges on both sides along the first direction X only including red sub-pixels and blue sub-pixels.

[0103] In some embodiments, see Figure 4-Figure 6 In the same pixel unit 110, the fourth sub-pixel 124 and the first sub-pixel 121 can be located on one side of the pixel unit 110 along the second direction Y, so that at least part of the edges of the pixel arrangement structure 100 on both sides along the second direction Y are arranged in sequence by the fourth sub-pixel 124 and the first sub-pixel 121, avoiding the situation where the same-color sub-pixels 120 are concentrated on at least part of the edge, thereby improving the color edge phenomenon of at least part of the edge. In addition, the white sub-pixel 125 and the third sub-pixel 123 can be located on the other side of the pixel unit 110 along the second direction Y, so that at least part of the edges of the pixel arrangement structure 100 on both sides along the second direction Y are arranged in sequence by the white sub-pixel 125 and the third sub-pixel 123. The white sub-pixel 125 can weaken the color edge phenomenon caused by the third sub-pixel 123, thereby improving the color edge phenomenon of the edges of the pixel arrangement structure 100 on both sides along the second direction Y, thereby improving the display effect of the pixel arrangement structure 100, the display panel and the display device.

[0104] In some embodiments, see Figure 7 In the same pixel unit 110, the fourth sub-pixel 124 and the third sub-pixel 123 are located on one side of the pixel unit 110 along the second direction Y, and the white sub-pixel 125 and the first sub-pixel 121 are located on the other side of the pixel unit 110 along the second direction Y, thereby improving the color edge phenomenon of the edges on both sides of the pixel arrangement structure 100 along the second direction Y, so as to improve the display effect of the pixel arrangement structure 100, the display panel and the display device. The principle has been explained and will not be repeated here.

[0105] In some embodiments, see Figure 3In the same pixel unit 110, the line connecting the center of the second sub-pixel 122 and the center of the fourth sub-pixel 124 may obliquely intersect with the first direction X. For example, the second sub-pixel 122 and the fourth sub-pixel 124 may be arranged along the fourth direction, and the fourth direction may obliquely intersect with the first direction X, so that the second sub-pixel 122 and the fourth sub-pixel 124 may be slightly staggered in the first direction X, thereby improving the continuity of the arrangement of the second sub-pixel 122 and the fourth sub-pixel 124 in the oblique direction of each pixel unit 110, so that the continuity of the arrangement of the green sub-pixel in the oblique direction is higher, which is conducive to the display of arcs or fine text. Among them, the center of the second sub-pixel 122 may refer to the geometric center of the second sub-pixel 122.

[0106] In some embodiments, see Figure 3 In the same pixel unit row 100a, the lines connecting the centers of the second sub-pixels 122 of each pixel unit 110 are on the same straight line, so that the arrangement of the green sub-pixels in the straight line direction has a high continuity, which is conducive to the display of arcs or fine text.

[0107] For example, see Figure 3 In the same pixel unit row 100a, the line connecting the centers of the second sub-pixels 122 of each pixel unit 110 can extend along the first direction X, so that the arrangement of the green sub-pixels in the first direction X has a higher continuity, which is beneficial to the display of arcs or fine text.

[0108] It is understandable that, in any two pixel units 110 , the arrangement of the multiple sub-pixels 120 of one pixel unit 110 may be the same as the arrangement of the multiple sub-pixels 120 of the other pixel unit 110 , or may be at least partially different.

[0109] The first pixel unit 111 and the second pixel unit 112 provided in the embodiment of the present application are described below.

[0110] In some embodiments, see Figure 3, the plurality of pixel units 110 may include a first pixel unit 111 and a second pixel unit 112, and the direction from the first sub-pixel 121 to the third sub-pixel 123 in the first pixel unit 111 is opposite to the direction from the first sub-pixel 121 to the third sub-pixel 123 in the second pixel unit 112. The direction from the fourth sub-pixel 124 to the white sub-pixel 125 in the first pixel unit 111 is opposite to the direction from the fourth sub-pixel 124 to the white sub-pixel 125 in the second pixel unit 112. In the same pixel unit row 100a, the first pixel unit 111 and the second pixel unit 112 may be alternately arranged along the first direction X. Thus, in two adjacent pixel units 110 in the same pixel unit row 100a, taking the two adjacent pixel units 110 in the first pixel unit row 101a as an example, the four sub-pixels 120 on one side along the second direction Y are respectively the fourth sub-pixel 124, the first sub-pixel 121, the white sub-pixel 125 and the third sub-pixel 123, and the four sub-pixels 120 on the other side along the second direction Y are respectively the white sub-pixel 125, the third sub-pixel 123, the fourth sub-pixel 124 and the first sub-pixel 121, so that the adjacent pixel units 110 in the same pixel unit row 100a are Sub-pixels 120 of four colors, namely, red sub-pixels, blue sub-pixels, green sub-pixels and white sub-pixels 125, are arranged on both sides of the second direction Y of two adjacent pixel units 110, so that the edges of the pixel arrangement structure 100 on both sides along the second direction Y can be arranged with sub-pixels 120 of four colors, namely, red sub-pixels, blue sub-pixels, green sub-pixels and white sub-pixels 125, so as to better avoid the situation where the same color sub-pixels 120 are concentrated on the edges of the pixel arrangement structure 100 on both sides along the second direction Y, thereby better improving the color fringing phenomenon of the edge.

[0111] In an embodiment where the fourth sub-pixel 124 and the first sub-pixel 121 in the same pixel unit 110 are located on the same side of the pixel unit 110 along the second direction Y, in the same row of pixel unit rows 100a, the fourth sub-pixel 124 and the first sub-pixel 121 of one of two adjacent pixel units 110 are mixed to appear yellow, and the yellow color fringing phenomenon can be alleviated by combining the white sub-pixel 125 of the other of the two adjacent pixel units 110.

[0112] For example, see Figure 4 and Fig. 9 The first pixel unit 111 of the first pixel unit row 101a and the first pixel unit 111 of the second pixel unit row 102a are arranged relatively along the second direction Y, and the second pixel unit 112 of the first pixel unit row 101a and the second pixel unit 112 of the second pixel unit row 102a are arranged relatively along the second direction Y, so that there are no sub-pixels 120 of the same color close to each other and concentrated between two adjacent rows of pixel unit rows 100a, which is beneficial to the display effect.

[0113] For example, see Figure 3 and Figure 8 In two first sub-pixel groups 120a adjacent to each other along the second direction Y, the first sub-pixel 121 of one first sub-pixel group 120a is adjacent to the first sub-pixel 121 of the other first sub-pixel group 120a, or the third sub-pixel 123 of one first sub-pixel group 120a is adjacent to the third sub-pixel 123 of the other first sub-pixel group 120a. In this way, the sub-pixels 120 of the same color between the two adjacent first sub-pixel groups 120a are close to each other, so that the sub-pixels 120 of the same color can share the opening of the evaporation mask, which is conducive to increasing the aperture ratio. And / or, in two second sub-pixel groups 120b adjacent to each other along the second direction Y, the fourth sub-pixel 124 of one second sub-pixel group 120b is adjacent to the fourth sub-pixel 124 of the other second sub-pixel group 120b, or the white sub-pixel 125 of one second sub-pixel group 120b is adjacent to the white sub-pixel 125 of the other second sub-pixel group 120b. In this way, the sub-pixels 120 of the same color between two adjacent second sub-pixel groups 120 b are close to each other, so that the sub-pixels 120 of the same color can share the opening of the evaporation mask, which is beneficial to increase the aperture ratio.

[0114] In some embodiments, the first pixel unit 111 of the first pixel unit row 101a and the second pixel unit 112 of the second pixel unit row 102a are arranged relatively along the second direction Y, and the second pixel unit 112 of the first pixel unit row 101a and the first pixel unit 111 of the second pixel unit row 102a are arranged relatively along the second direction Y, so that the sub-pixels 120 of the same color between two adjacent pixel unit rows 100a are close to each other, so that the sub-pixels 120 of the same color in the two adjacent pixel unit rows 100a can be adjacent to each other, so that the sub-pixels 120 of the same color can share the opening of the evaporation mask, which is conducive to increasing the aperture ratio. In the embodiment where the shapes of the first sub-pixel 121, the third sub-pixel 123, the fourth sub-pixel 124 and the white sub-pixel 125 are roughly triangular, the process margin area of ​​the two adjacent sub-pixels 120 of the same color can be moved to the oblique direction, which is further conducive to increasing the aperture ratio.

[0115] The shape of the sub-pixel 120 provided in the embodiment of the present application is described below.

[0116] In some examples, the shapes of the first sub-pixel 121, the second sub-pixel 122, the third sub-pixel 123, the fourth sub-pixel 124, and the white sub-pixel 125 are different. In other examples, the shapes of at least two of the first sub-pixel 121, the second sub-pixel 122, the third sub-pixel 123, the fourth sub-pixel 124, and the white sub-pixel 125 may be the same. The embodiment of the present application is described by taking the example that the shape of the second sub-pixel 122 is different from the shape of the fourth sub-pixel 124.

[0117] It should be noted that the display panel provided in the embodiment of the present application can adjust the graphic size, shape, position and other parameters of at least one of the first sub-pixel 121, the second sub-pixel 122, the third sub-pixel 123, the fourth sub-pixel 124 and the white sub-pixel 125 according to actual requirements, so as to facilitate the adjustment of color deviation.

[0118] In some embodiments, see Figure 3 The shape of the second sub-pixel 122 can be a strip (for example, a strip rectangle), the second sub-pixel 122 can extend along the first direction X, the length of the second sub-pixel 122 in the first direction X is greater than the width in the second direction Y, so that the size occupied by the second sub-pixel 122 along the second direction Y is smaller, which can improve the setting flexibility of the second sub-pixel 122, and is conducive to reducing the distance between the second sub-pixel 122 and the first sub-pixel 121 and the third sub-pixel 123 along the second direction Y, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio. In addition, it is also conducive to increasing the setting area of ​​the first sub-pixel 121 and / or the third sub-pixel 123, thereby increasing the service life of the first sub-pixel 121 and / or the third sub-pixel 123.

[0119] In some embodiments, at least one of the first sub-pixel 121, the third sub-pixel 123, the fourth sub-pixel 124, and the white sub-pixel 125 may include a first side 1201, a second side 1202, and a third side 1203 connected end to end, and the outer contour of the figure enclosed by the first side 1201, the second side 1202, and the third side 1203 is a triangle. In this way, the shape of the triangle is relatively simple, which can reduce the difficulty of manufacturing the sub-pixel 120.

[0120] For example, see Figure 3 The first side 1201 may be parallel to the first direction X, so that the display panel has less jagged feeling when displaying the bar pattern in the first direction X. Alternatively, the first side 1201 may be parallel to the second direction Y or other directions.

[0121] For example, see Figure 3, the second side 1202 and the third side 1203 may both be obliquely intersected with the first direction X, so that the display panel may have a smaller sense of sawtooth when displaying a bar pattern inclined at a direction of 45°. For example, the angle between the second side 1202 and the first direction X may be 45°, so that the sense of sawtooth when the display panel displays a bar pattern inclined at a direction of 45° may be better alleviated. For another example, the angle between the third side 1203 and the first direction X may be 45°, so that the sense of sawtooth when the display panel displays a bar pattern inclined at a direction of 45° may be better alleviated.

[0122] For example, the second side 1202 and the third side 1203 may be perpendicular to each other (ie, 90°), thereby reducing the difficulty of arranging the second side 1202 and the third side 1203. Alternatively, the angle between the second side 1202 and the third side 1203 may be other angles.

[0123] Exemplarily, the length of the second side 1202 can be equal to the length of the third side 1203, that is, the triangle formed by the first side 1201, the second side 1202 and the third side 1203 can be an isosceles triangle, so that the pattern of the sub-pixel 120 in the pixel unit 110 is more regular, which is beneficial to increasing the light-emitting area of ​​the sub-pixel 120.

[0124] Of course, the shape of any one of the first sub-pixel 121, the second sub-pixel 122, the third sub-pixel 123, the fourth sub-pixel 124 and the white sub-pixel 125 may also be other polygonal, elliptical, circular or other shapes.

[0125] For example, see Figure 3 In the same sub-pixel 120, a curved edge 1204 may be formed between the second side 1202 and the third side 1203, and the curved edge 1204 may be convexly arranged in a direction away from the center of the sub-pixel 120, and the curved edge 1204 may be convexly arranged along one side of the second direction Y, or the curved edge 1204 may be convexly arranged along one side of other directions. The embodiment of the present application is described by taking the curved edge 1204 convexly arranged along one side of the second direction Y as an example.

[0126] For example, see Figure 5In the same first sub-pixel group 120a, the arc-shaped edge 1204 of the first sub-pixel 121 and the arc-shaped edge 1204 of the third sub-pixel 123 can be arranged opposite to each other along the second direction Y, and the first side edge 1201 of the first sub-pixel 121 and the first side edge 1201 of the third sub-pixel 123 can be arranged relatively to each other along the second direction Y, so that the distance between the first side edge 1201 of the first sub-pixel 121 and the first side edge 1201 of the third sub-pixel 123 can be set smaller, which is beneficial to shorten the distance between the first sub-pixel 121 and the third sub-pixel 123, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio.

[0127] For example, see Figure 3 In the same first sub-pixel group 120a, the arc-shaped edge 1204 of the first sub-pixel 121 and the arc-shaped edge 1204 of the third sub-pixel 123 may be arranged opposite to each other along the second direction Y. Alternatively, in the same first sub-pixel group 120a, the arc-shaped edge 1204 of the first sub-pixel 121 and the arc-shaped edge 1204 of the third sub-pixel 123 may both be arranged to protrude along the same side of the second direction Y, thereby satisfying more usage scenarios.

[0128] For example, see Figure 3 In the same second sub-pixel group 120b, the arc-shaped edge 1204 of the fourth sub-pixel 124 and the arc-shaped edge 1204 of the white sub-pixel 125 are arranged opposite to each other along the second direction Y, and the first side edge 1201 of the fourth sub-pixel 124 and the first side edge 1201 of the white sub-pixel 125 are arranged relatively to each other along the second direction Y, so that the distance between the first side edge 1201 of the fourth sub-pixel 124 and the first side edge 1201 of the white sub-pixel 125 can be set smaller, which is beneficial to shorten the distance between the fourth sub-pixel 124 and the white sub-pixel 125, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio.

[0129] For example, see Figure 5 , in the same second sub-pixel group 120b, the arc-shaped edge 1204 of the fourth sub-pixel 124 and the arc-shaped edge 1204 of the white sub-pixel 125 are arranged opposite to each other along the second direction Y. Alternatively, in the same second sub-pixel group 120b, the arc-shaped edge 1204 of the fourth sub-pixel 124 and the arc-shaped edge 1204 of the white sub-pixel 125 can both be arranged to protrude along the same side of the second direction Y, thereby satisfying more usage scenarios.

[0130] See also Figure 3In an embodiment in which, in the same pixel unit 110, the fourth sub-pixel 124 and the first sub-pixel 121 are located on one side of the pixel unit 110 along the second direction Y, and the white sub-pixel 125 and the third sub-pixel 123 are located on the other side of the pixel unit 110 along the second direction Y, the protruding directions of the arc-shaped edge 1204 of the fourth sub-pixel 124 and the arc-shaped edge 1204 of the first sub-pixel 121 are different (for example, opposite), and the extension directions of the side of the fourth sub-pixel 124 close to the first sub-pixel 121 and the side of the first sub-pixel 121 close to the fourth sub-pixel 124 are closer, so that the distance between the side of the fourth sub-pixel 124 close to the first sub-pixel 121 and the side of the first sub-pixel 121 close to the fourth sub-pixel 124 is closer, which is beneficial to shortening the distance between the fourth sub-pixel 124 and the first sub-pixel 121, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio. For another example, the arcuate edge 1204 of the white sub-pixel 125 and the arcuate edge 1204 of the third sub-pixel 123 have different protruding directions (for example, opposite), so that the side of the white sub-pixel 125 close to the third sub-pixel 123 and the side of the third sub-pixel 123 close to the white sub-pixel 125 are closer in extension direction, so that the distance between the side of the white sub-pixel 125 close to the third sub-pixel 123 and the side of the third sub-pixel 123 close to the white sub-pixel 125 is closer, which is conducive to reducing the distance between the white sub-pixel 125 and the third sub-pixel 123, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio. For another example, the side of the fourth sub-pixel 124 close to the first sub-pixel 121 is parallel to the side of the first sub-pixel 121 close to the fourth sub-pixel 124, so that the sub-pixels 120 are further compactly arranged, the arrangement space is fully utilized, and the aperture ratio is further improved. For another example, the side of the white sub-pixel 125 close to the third sub-pixel 123 is parallel to the side of the third sub-pixel 123 close to the white sub-pixel 125 , thereby further compactly arranging the sub-pixels 120 , making full use of the arrangement space, and further improving the aperture ratio.

[0131] See also Figure 7In the same pixel unit 110, in which the fourth sub-pixel 124 and the third sub-pixel 123 are located on one side of the pixel unit 110 along the second direction Y, and the white sub-pixel 125 and the first sub-pixel 121 are located on the other side of the pixel unit 110 along the second direction Y, the arc-shaped edge 1204 of the fourth sub-pixel 124 and the arc-shaped edge 1204 of the third sub-pixel 123 have different protruding directions (for example, opposite), so that the fourth sub-pixel 124 and the third sub-pixel 123 are closer, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio. The principle has been explained and will not be repeated. The arc-shaped edge 1204 of the white sub-pixel 125 and the arc-shaped edge 1204 of the first sub-pixel 121 have different protruding directions (for example, opposite), so that the white sub-pixel 125 and the first sub-pixel 121 are closer, so that the sub-pixels 120 are compactly arranged, and the arrangement space is fully utilized, thereby improving the aperture ratio. The principle has been explained and will not be repeated. For example, the side of the fourth sub-pixel 124 close to the third sub-pixel 123 is parallel to the side of the third sub-pixel 123 close to the fourth sub-pixel 124, so that the sub-pixels 120 are further arranged compactly, and the arrangement space is fully utilized, thereby improving the aperture ratio. For another example, the side of the white sub-pixel 125 close to the first sub-pixel 121 is parallel to the side of the first sub-pixel 121 close to the white sub-pixel 125, so that the sub-pixels 120 are further arranged compactly, and the arrangement space is fully utilized, thereby improving the aperture ratio.
