Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to an array substrate, a display panel, and a display device. Background Art

[0002] OLED (Organic Light Emitting Diode) display panels have advantages such as self-luminescence without backlight, being thin and light, and low power consumption, and are thus highly favored by users.

[0003] In an OLED display, the pixel arrangement mode greatly affects the actual display effect. In the prior art, the pixel arrangement modes of OLED display panels include RGBG arrangement, YYG arrangement, diamond arrangement, etc. Among them, the RGBG arrangement has blurred text, thick strokes, and blurred picture display; the YYG arrangement has obvious text font jaggedness; the diamond arrangement has clear text, thin strokes, and relatively slight jaggedness, which is superior to the RGBG arrangement and the YYG arrangement. Therefore, the diamond arrangement mode is most widely used in the pixel arrangement modes of OLED display panels, and most of the current mainstream pixel arrangements are diamond-like arrangements.

[0004] However, most of the existing diamond-like arrangements have problems such as aperture ratio loss, resulting in waste of display space. Summary of the Invention

[0005] The present invention provides an array substrate, a display panel, and a display device to improve the aperture ratio.

[0006] In a first aspect, the present invention provides an array substrate, including: a plurality of pixel repeating units arranged in an array;

[0007] The pixel repeating unit includes a first repeating unit and a second repeating unit, and the first repeating unit and the second repeating unit are arranged along a first direction;

[0008] The first repeating unit includes a first sub-pixel, a second sub-pixel, and a third pixel group arranged in sequence along a second direction, and the third pixel group includes two third sub-pixels arranged side by side along the first direction; the second repeating unit includes a second sub-pixel, the third pixel group, and the first sub-pixel arranged in sequence along the second direction; the first sub-pixel, the second sub-pixel, and the third sub-pixel have different light-emitting colors; the first direction and the second direction intersect;

[0009] The third mask plate opening corresponding to any third sub-pixel is adjacent to the first mask plate opening corresponding to the first sub-pixel adjacent to the third sub-pixel; the third mask plate opening corresponding to any third sub-pixel is adjacent to the second mask plate opening corresponding to the second sub-pixel adjacent to the third sub-pixel; the adjacent first mask plate opening and the second mask plate opening are adjacent.

[0010] In a second aspect, the present invention provides a display panel, including the array substrate according to any embodiment of the present invention.

[0011] In a third aspect, the present invention provides a display device, including the display panel according to any embodiment of the present invention.

[0012] The technical solution of the embodiment of the present invention is as follows: by setting the array substrate to include a plurality of pixel repeating units arranged in an array, the pixel repeating unit includes a first repeating unit and a second repeating unit arranged along a first direction, the first repeating unit includes a first sub-pixel, a second sub-pixel, and a third pixel group arranged in sequence along a second direction, the second repeating unit includes a second sub-pixel, a third pixel group, and a first sub-pixel arranged in sequence along the second direction, and the third pixel group includes two third sub-pixels arranged side by side along the first direction. Thus, high-PPI display can be achieved by means of pixel borrowing. Further, by setting the first mask plate opening corresponding to the adjacent first sub-pixel and the third sub-pixel and the third mask plate opening to be adjacent, the second mask plate opening corresponding to the adjacent second sub-pixel and the third sub-pixel and the third mask plate opening to be adjacent, and the first mask plate opening corresponding to the adjacent first sub-pixel and the second sub-pixel and the second mask plate opening to be adjacent, so that the two mask plate openings corresponding to any two adjacent sub-pixels with different emission colors are adjacent to each other. Thus, the distance between adjacent sub-pixels can be minimized as much as possible, the waste of the display space can be reduced, and the aperture ratio can be improved.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] An OLED display panel generally includes sub-pixels of at least two different emission colors. During the preparation process, each sub-pixel generally uses a vapor deposition film-forming technique to form an organic light-emitting device at the corresponding sub-pixel position on the array substrate by passing the light-emitting layer material through a mask. It can be understood that when the pitch between sub-pixels increases, the aperture ratio will be sacrificed.

[0027] Exemplarily, Figure 1It is a schematic diagram of an existing pixel arrangement method, belonging to a type of diamond arrangement, which can be called a tripod arrangement. As Figure 1 shown, the tripod arrangement is formed by arranging sub-pixels of three different emission colors (represented by different filling methods) according to a certain rule. The three sub-pixels are a red sub-pixel 01, a green sub-pixel 02, and a blue sub-pixel 03. The center connection lines of two red sub-pixels 01 and two blue sub-pixels 03 adjacent to the same green sub-pixel 02 form a trapezoid, and the center connection lines of four green sub-pixels adjacent to the same red sub-pixel 01 / blue sub-pixel 03 form a trapezoid. During the preparation process, the red sub-pixel 01, the green sub-pixel 02, and the blue sub-pixel 03 are respectively vapor-deposited with the light-emitting layer material using different mask plates. Figure 1 In Figure 1 , the wireframe (such as 011) around the red sub-pixel 01 represents the opening on the mask plate corresponding to the red sub-pixel, the wireframe (such as 021) around the green sub-pixel 02 represents the opening on the mask plate corresponding to the green sub-pixel, and the wireframe (such as 031) around the blue sub-pixel 03 represents the opening on the mask plate corresponding to the blue sub-pixel. Considering the actual vapor-deposition process accuracy, the opening area of the mask plate is usually larger than the opening area of the sub-pixel. In addition, to avoid color mixing, the projection relationship between the mask plate openings on different mask plates hardly overlaps.

[0028] The aperture ratio can be understood as the area ratio of the opening areas of all sub-pixels in the entire display area. From Figure 1 it can be seen that in the existing type of diamond arrangement method, since the center connection lines of two red sub-pixels 01 and two blue sub-pixels 03 adjacent to the same green sub-pixel 02 form a trapezoid, and the center connection lines of four green sub-pixels adjacent to the same red sub-pixel 01 / blue sub-pixel 03 form a trapezoid, the distance between some sub-pixels increases, resulting in waste of space in the display area (such as Figure 1 the area between the mask plate openings within the area marked by the elliptical dotted line in Figure 1 is wasted), leading to a decrease in the aperture ratio.

[0029] To solve the above problems, an embodiment of the present invention provides an array substrate, which includes a plurality of pixel repeating units arranged in an array; the pixel repeating unit includes a first repeating unit and a second repeating unit, and the first repeating unit and the second repeating unit are arranged along a first direction; the first repeating unit includes a first sub-pixel, a second sub-pixel, and a third pixel group arranged in sequence along a second direction, and the third pixel group includes two third sub-pixels arranged side by side along the first direction; the second repeating unit includes a second sub-pixel, a third pixel group, and a first sub-pixel arranged in sequence along the second direction; the first sub-pixel, the second sub-pixel, and the third sub-pixel have different emission colors; the first direction and the second direction intersect; the third mask plate opening corresponding to any third sub-pixel is adjacent to the first mask plate opening corresponding to the first sub-pixel adjacent to the third sub-pixel; the third mask plate opening corresponding to any third sub-pixel is adjacent to the second mask plate opening corresponding to the second sub-pixel adjacent to the third sub-pixel; and the adjacent first mask plate opening and the second mask plate opening are adjacent to each other.

[0030] With the above solution, since the first mask plate opening corresponding to the adjacent first sub-pixel and third sub-pixel is adjacent to the third mask plate opening, the second mask plate opening corresponding to the adjacent second sub-pixel and third sub-pixel is adjacent to the third mask plate opening, and the first mask plate opening corresponding to the adjacent first sub-pixel and second sub-pixel is adjacent to the second mask plate opening, the two mask plate openings corresponding to any two adjacent sub-pixels with different emission colors are adjacent to each other, so that the distance between adjacent sub-pixels can be minimized as much as possible, the waste of the display space can be reduced, and the aperture ratio can be improved.

[0031] The above is the core idea of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. Hereinafter, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application.

[0032] Figure 2 It is a schematic structural diagram of an array substrate provided by an embodiment of the present invention. Figure 3 is Figure 2 a schematic structural diagram of a pixel repeating unit in the shown array substrate. As Figure 2 and Figure 3As shown in the figure, the array substrate 10 provided by the embodiment of the present invention includes a plurality of pixel repeating units 1 arranged in an array; the pixel repeating unit 1 includes a first repeating unit 101 and a second repeating unit 102, and the first repeating unit 101 and the second repeating unit 102 are arranged along a first direction; the first repeating unit 101 includes a first sub-pixel 11, a second sub-pixel 12, and a third pixel group 130 arranged in sequence along a second direction, and the third pixel group 130 includes two third sub-pixels 13 arranged side by side along the first direction; the second repeating unit 102 includes a second sub-pixel 12, a third pixel group 130, and a first sub-pixel 11 arranged in sequence along the second direction; the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 have different emission colors; the first direction and the second direction intersect; the third mask plate opening 23 corresponding to any third sub-pixel 13 is adjacent to the first mask plate opening 21 corresponding to the first sub-pixel 11 adjacent to the third sub-pixel 13; the third mask plate opening 23 corresponding to any third sub-pixel 13 is adjacent to the second mask plate opening 22 corresponding to the second sub-pixel 12 adjacent to the third sub-pixel 13; the adjacent first mask plate opening 21 and the second mask plate opening 22 are adjacent to each other.

[0033] Optionally, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel respectively and are different from each other. Combining Figure 2 and Figure 3 As shown in the figure, in the embodiment of the present invention, by setting the pixel repeating unit 1 to include a first repeating unit 101 and a second repeating unit 102 arranged along the first direction, the first repeating unit 101 includes a first sub-pixel 11, a second sub-pixel 12, and a third pixel group 130 arranged in sequence along the second direction, the second repeating unit 102 includes a second sub-pixel 12, a third pixel group 130, and a first sub-pixel 11 arranged in sequence along the second direction, and the third pixel group 130 includes two third sub-pixels 13 arranged side by side along the first direction, any third sub-pixel 13 in the array substrate 10 can form two pixels with two pairs of adjacent first sub-pixels 11 and second sub-pixels 12, and there is a pair of shared first sub-pixels 11 and second sub-pixels 12 between the two third sub-pixels 13 in the same third pixel group 130. In this way, color display can be realized by means of pixel borrowing, and the number of pixels per inch (Pixels Per Inch, hereinafter referred to as PPI) in the display panel can be increased by using a limited number of sub-pixels, realizing high-PPI display.

[0034] Optionally, the first direction and the second direction are orthogonal, and such a setting facilitates simplifying the arrangement difficulty of the sub-pixels. It should be noted that Figure 2For illustration purposes, only the case where the first direction is the column direction and the second direction is the row direction is taken as an example. In other embodiments, the first direction can also be the row direction and the second direction can be the column direction. The embodiments of the present invention do not limit this. Subsequently, only the case where the first direction is the column direction and the second direction is the row direction is taken as an example for description.

[0035] Further, the sub-pixel includes an organic light-emitting device and a pixel circuit for driving the light-emitting device to emit light. In the array substrate, the corresponding relationship between the pixel circuit and the organic light-emitting element can be a one-to-one correspondence, or one pixel circuit can correspond to multiple organic light-emitting elements. The embodiments of the present invention do not limit this. Exemplarily, Figure 4 is along Figure 3 the schematic cross-sectional structure diagram of the array substrate intercepted by AA' in, referring to Figure 3 and Figure 4 shown, the array substrate 10 includes a substrate 3 and a pixel defining layer 4 located on one side of the substrate 3. The pixel defining layer 4 includes a plurality of pixel openings. The plurality of pixel openings include a plurality of first pixel openings 41, a plurality of second pixel openings 42, and a plurality of third pixel openings 43. The first pixel opening 41 is correspondingly arranged with the first sub-pixel 11, the second pixel opening 42 is correspondingly arranged with the second sub-pixel 12, and the third pixel opening 43 is correspondingly arranged with the third sub-pixel 13. In addition, as Figure 4 shown, a pixel circuit layer 5 is provided between the substrate 3 and the pixel defining layer 4. A plurality of organic light-emitting devices 6 are formed on the side of the pixel circuit layer 5 away from the substrate 3. The pixel circuits in the pixel circuit layer 5 are electrically connected to the organic light-emitting devices 6 for driving the organic light-emitting devices to emit light. Continuing to refer to Figure 4 , the organic light-emitting device 6 includes an anode 61, a cathode 63, and a light-emitting layer 62 located therebetween. The light-emitting layer 62 is located within the pixel opening. Specifically, the light-emitting layer of the organic light-emitting device in the first sub-pixel 11 is located within the first pixel opening 41, the light-emitting layer of the organic light-emitting device in the second sub-pixel 12 is located within the second pixel opening 42, and the light-emitting layer of the organic light-emitting device in the third sub-pixel 13 is located within the third pixel opening 43.

[0036] It should be noted that Figure 4 only one first pixel opening 41 in the pixel defining layer 4 is taken as an example for illustration. The setting manners of the second pixel opening 42 and the third pixel opening 43 are the same as this and will not be elaborated here.

[0037] It should also be noted that the pixel circuit layer 5 includes a plurality of pixel circuits, Figure 4 only one thin film transistor in the pixel circuit layer 5 is schematically shown. The embodiments of the present invention do not specifically limit the structure of the pixel circuit.

[0038] As described above, when performing the evaporation process of the light-emitting layer material in the organic light-emitting device, different sub-pixels with different emission colors use different masks for the evaporation of the light-emitting layer material. Specifically, when performing the evaporation process of the light-emitting layer material corresponding to each sub-pixel, 3 different masks need to be used in sequence to evaporate different light-emitting layer materials in the pixel openings corresponding to the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, respectively, to form an organic light-emitting device with different emission colors. Exemplarily, the first mask with a plurality of first mask openings 21 can be used to block the array substrate 10. In this way, only the first pixel opening 41 is exposed by the first mask opening 21, so that the light-emitting layer material of the first sub-pixel 11 can be evaporated in the first pixel opening 41; then the second mask with a plurality of second mask openings 22 is used to block the array substrate 10. In this way, only the second pixel opening 42 is exposed by the second mask opening 22, so that the light-emitting layer material of the second sub-pixel 12 can be evaporated in the second pixel opening 42; finally, the third mask with a plurality of third mask openings 23 is used to block the array substrate 10. In this way, only the third pixel opening 43 is exposed by the third mask opening 23, so that the light-emitting layer material of the third sub-pixel 13 can be evaporated in the third pixel opening 43.

[0039] In the embodiments of the present invention, the expression regarding the adjacency of the mask openings can be understood as follows: the first mask, the second mask, and the third mask are respectively orthogonally projected onto the substrate 3. The orthogonal projections of the first mask opening 21 and the third mask opening 23 corresponding to the adjacent first sub-pixel 11 and third sub-pixel 13 on the substrate 3 are adjacent; the orthogonal projections of the second mask opening 22 and the third mask opening 23 corresponding to the adjacent second sub-pixel 12 and third sub-pixel 13 on the substrate 3 are adjacent; the orthogonal projections of the first mask opening 21 and the second mask opening 22 corresponding to the adjacent first sub-pixel 11 and second sub-pixel 12 on the substrate 3 are adjacent.

[0040] From Figure 2 It can be seen that in this embodiment, by setting the two mask openings corresponding to any two adjacent sub-pixels with different emission colors to be adjacent to each other, the distance between adjacent sub-pixels can be minimized as much as possible. Specifically, the distance between adjacent pixel openings is reduced, that is, the distance between the adjacent first pixel opening 41 and third pixel opening 43 in the pixel defining layer is reduced, the distance between the adjacent second pixel opening 42 and third pixel opening 43 is reduced, and the distance between the adjacent first pixel opening 41 and second pixel opening 42 is reduced. Furthermore, the waste of the display space is reduced, the utilization rate of the display space is improved, and the aperture ratio is increased.

[0041] It should be noted that Figure 2 and Figure 3Only the first sub-pixel opening 41, the second sub-pixel opening 42, the third sub-pixel opening 43, the first mask plate opening 21, the second mask plate opening 22, and the third mask plate opening 23 are taken as an example of polygons for illustration, and this setting method is not a limitation. Those skilled in the art can adopt any mask plate opening shape that can make the two mask plate openings corresponding to any two adjacent sub-pixels with different emission colors adjacent to each other. The embodiments of the present invention do not limit this, and will be described in detail later.

[0042] It should also be noted that the purpose of drawing the first mask plate opening 21, the second mask plate opening 22, and the third mask plate opening 23 in the accompanying drawings of the embodiments of the present invention is to show the corresponding relationship between the pixel openings and the mask plate openings, and to facilitate reflecting the technical effects of the technical solutions of the embodiments of the present invention. It can be understood that the mask plate / mask plate opening does not belong to the structure of the array substrate 10.

[0043] The technical solution of the embodiment of the present invention is to set the array substrate to include a plurality of pixel repeating units arranged in an array as follows: the pixel repeating unit includes a first repeating unit and a second repeating unit arranged along a first direction. The first repeating unit includes a first sub-pixel, a second sub-pixel, and a third pixel group arranged in sequence along a second direction. The second repeating unit includes a second sub-pixel, a third pixel group, and a first sub-pixel arranged in sequence along the second direction. The third pixel group includes two third sub-pixels arranged side by side along the first direction. Thus, high-PPI display can be achieved by means of pixel borrowing. Further, by setting the first mask plate opening and the third mask plate opening corresponding to the adjacent first sub-pixel and third sub-pixel to be adjacent, the second mask plate opening and the third mask plate opening corresponding to the adjacent second sub-pixel and third sub-pixel to be adjacent, and the first mask plate opening and the second mask plate opening corresponding to the adjacent first sub-pixel and second sub-pixel to be adjacent, the two mask plate openings corresponding to any two adjacent sub-pixels with different emission colors are adjacent to each other. Thus, the distance between adjacent sub-pixels can be minimized as much as possible, the waste of the display space can be reduced, and the aperture ratio can be improved.

[0044] It should be noted that for the two third mask plate openings 23 corresponding to the two third sub-pixels 13 in the same third pixel group 130, Figure 2 Only the two third sub-pixels 13 in the same third pixel group 130 are respectively corresponding to one third mask plate opening 23, and there is a certain distance between these two third mask plate openings 23 as an example for illustration, and this setting method is not a limitation. Exemplarily, Figure 5 is a schematic structural diagram of another pixel repeating unit in the array substrate provided by the embodiment of the present invention. As Figure 5 shown, in other embodiments, optionally, the two third mask plate openings 23 corresponding to the two third sub-pixels 13 in the third pixel group 130 are adjacent.

[0045] Since the third mask openings 23 are located on the same mask, when two adjacent third mask openings 23 are adjacent to each other, a common mask opening 230 can be formed. At this time, two third sub-pixels 13 in the third pixel group 130 share the common mask opening 230. With this arrangement, since the two sub-pixels in the third pixel group 130 are third sub-pixels 13 with the same emission color and there is no color mixing problem, by setting the two third mask openings 23 corresponding to the two third sub-pixels 13 in the third pixel group 130 to be adjacent to each other to form a common mask opening 230, on the one hand, the manufacturing difficulty of the mask can be reduced, and on the other hand, the distance between the third sub-pixels 13 (or the distance between the two corresponding third pixel openings 43 in the pixel defining layer) can be further reduced, further improving the aperture ratio. Subsequently, only the case where the two third mask openings 23 corresponding to the two third sub-pixels 13 in the same third pixel group 130 are adjacent to each other to form a common mask opening 230 will be taken as an example for illustration.

[0046] Based on the above embodiments, the shapes of the first mask opening 21, the second mask opening 22, and the third mask opening 23 will be further described below.

[0047] As a feasible implementation manner, referring to Figure 3 , optionally, the first mask opening 21 is a first polygon, the second mask opening 22 is a second polygon, and the third mask opening 23 is a third polygon; there is a set of opposite sides adjacent between two adjacent first mask openings 21 and second mask openings 22; there is a set of opposite sides adjacent between two adjacent first mask openings 21 and third mask openings 23; there is a set of opposite sides adjacent between two adjacent second mask openings 22 and third mask openings 23. By setting the first mask opening 21, the second mask opening 22, and the third mask opening 23 to be all polygons, by reasonably setting the number of sides of each polygon, the orthographic projections of the first mask opening 21, the second mask opening 22, and the third mask opening 23 on the substrate can be adjacent to each other in pairs and fill each other, minimizing the distance between adjacent sub-pixels as much as possible, avoiding waste of the display space, and improving the aperture ratio.

[0048] Optionally, the number of sides of the first polygon is greater than or equal to seven, the number of sides of the second polygon is greater than or equal to seven, and the number of sides of the third polygon is greater than or equal to five. Taking a regular polygon as an example, when the distance from the center of the polygon to the vertex is fixed, the larger the number of sides, the larger the area. The shape of the mask opening is generally basically the same as that of the pixel opening. Therefore, in the embodiments of the present invention, by setting the number of sides of the first polygon to be greater than or equal to seven, the number of sides of the second polygon to be greater than or equal to seven, and the number of sides of the third polygon to be greater than or equal to five, the number of sides of the pixel opening can be adaptively increased, so as to increase the area of the pixel opening and further improve the aperture ratio.

[0049] Exemplarily, Figure 3 and Figure 5 Taking the first mask opening 21 as a heptagon, the second mask opening 22 as a heptagon, and the third mask opening 23 as a pentagon as an example for illustration, the difference between the two is that Figure 3 there is a certain distance between two third mask openings 23 corresponding to the same third pixel group 130 in Figure 5 two third mask openings 23 corresponding to the same third pixel group 130 in Figure 1 are adjacent to form a common mask opening 230, and the common mask opening 230 is a non-regular octagon. Research shows that compared with Figure 3 the prior art shown in Figure 5 the setting method shown in

[0050] Referring to Figure 5 , the first pixel opening 41 has a first projection on the substrate, the second pixel opening 42 has a second projection on the substrate, and the third pixel opening 43 has a third projection on the substrate. Optionally, the number of sides of the first projection (such as 41) is the same as the number of sides of the first polygon (such as 21), the number of sides of the second projection (such as 42) is the same as the number of sides of the second polygon (such as 22), and the number of sides of the third projection (such as 43) is less than or equal to the number of sides of the third polygon (such as 23).

[0051] Referring to Figure 4 and Figure 5 , the first projection can be understood as the orthographic projection on the substrate 3 of the side of the first pixel opening 41 close to the substrate. Similarly, the second projection can be understood as the orthographic projection on the substrate of the side of the second pixel opening 42 close to the substrate 3, and the third projection can be understood as the orthographic projection on the substrate of the side of the third pixel opening 43 close to the substrate 3.

[0052] In the embodiments of the present invention, by setting the number of sides of the first projection to be the same as the number of sides of the first polygon and the number of sides of the second projection to be the same as the number of sides of the second polygon, it can be ensured that the first pixel opening 41 and the second pixel opening 42 have a larger opening area and ensure the aperture ratio.

[0053] For the third pixel opening 43, the number of sides of the third projection can be set equal to the number of sides of the third polygon, or the number of sides of the third projection can be set less than the number of sides of the third polygon. Specifically, by setting the number of sides of the third projection to be the same as the number of sides of the third polygon, it is possible to ensure that the third pixel opening 43 has a relatively large opening area and ensure the aperture ratio; since the number of the third sub-pixels 13 is relatively large, by setting the number of sides of the opening shape of the third pixel opening 43 to be less than the number of sides of the corresponding third mask opening 23, the distance between the third pixel opening 43 and the first pixel opening 41 / the second pixel opening 42 can be appropriately increased, reducing the risk of color mixing. Those skilled in the art can set the number of sides of the opening of the third pixel opening 43 according to actual needs.

[0054] Exemplarily, Figure 5 Taking the number of sides of the third projection (such as 43) being equal to the number of sides of the third polygon (such as 23), both being pentagons as an example for illustration. Figure 6 It is a schematic structural diagram of another pixel repeating unit in the array substrate provided by the embodiment of the present invention, as Figure 6 shown. In other embodiments, when the third mask opening 23 is a pentagon, the third projection shape of the third pixel opening 43 can also be a quadrilateral.

[0055] Optionally, the first mask opening 21 and the second mask opening 22 can be regular polygons, and the shape of the third mask opening 23 fills at least part of the remaining area of the first mask opening 21 and the second mask opening 22, so that any two adjacent mask openings are adjacent to each other, improving the aperture ratio.

[0056] It should be noted that, Figure 3 , Figure 5 and Figure 6 Only taking the first mask opening 21 and the second mask opening 22 as heptagons and the third mask opening 23 as a pentagon as an example for illustration, those skilled in the art can set the first mask opening 21, the second mask opening 22 and the third mask opening 23 of other polygons according to needs, and the embodiments of the present invention do not limit this.

[0057] Exemplarily, Figure 7 It is a schematic structural diagram of another pixel repeating unit in the array substrate provided by the embodiment of the present invention, as Figure 7 shown. Optionally, the first mask opening 21 and the second mask opening 22 are octagons, and the third mask opening 23 is an irregular heptagon; Figure 7 In

[0058] In summary, in the above embodiments, the technical solution of the embodiments of the present invention is described in detail by taking the first mask opening 21, the second mask opening 22, and the third mask opening 23 as polygons. By setting the first mask opening 21, the second mask opening 22, and the third mask opening 23 as polygons, it is possible to make at least two adjacent mask openings corresponding to sub-pixels with different emission colors adjacent to each other, minimize the distance between adjacent sub-pixels as much as possible, reduce the waste of the display space, and improve the aperture ratio.

[0059] As another feasible implementation manner, optionally, the first mask opening 21, the second mask opening 22, and the third mask opening 23 are all circular or elliptical. With such a setting, the purpose of improving the aperture ratio can also be achieved. Moreover, when the radius of the circle is equal to the distance from the center of the polygon to the vertex, the area of the circle is larger, so that the aperture ratio can be further improved. Exemplarily, Figure 8 is a schematic structural diagram of another pixel repeating unit in the array substrate provided by the embodiments of the present invention. As Figure 8 shown, the first mask opening 21 and the second mask opening 22 are circular, and the common mask opening 230 is formed by splicing two ellipses ( Figure 8 In order to avoid color mixing, when designing the common mask opening 230, the edge of the common mask opening 230 is processed so that the common mask opening 230 does not overlap with the first mask opening 21 and the second mask opening 22). Correspondingly, the first pixel opening 41 and the second pixel opening 42 are circular, and the third pixel opening 43 is elliptical.

[0060] Based on the above embodiments, in combination with Figure 2 and Figure 3 shown, optionally, the center connection lines of two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 form a first virtual trapezoid 71; the center connection lines of four third sub-pixels 13 adjacent to the same first sub-pixel 11, or four third sub-pixels 13 adjacent to the same second sub-pixel 12 form a second virtual trapezoid 72. With such a setting, the pixel arrangement can be made more uniform and regular, which is beneficial to improving the display uniformity. Optionally, both the first virtual trapezoid 71 and the second virtual trapezoid 72 are isosceles trapezoids.

[0061] As Figure 2As shown, the first side and the second side of the first virtual trapezoid 71 are parallel, and the first side and the second side extend along the second direction; the third side and the fourth side of the second virtual trapezoid 72 are parallel, and the third side and the fourth side extend along the first direction. Optionally, the first direction and the second direction may be respectively one of the row direction and the column direction, and the embodiments of the present invention do not limit this. With such a setting, the center connection lines of the first sub-pixel 11 and the second sub-pixel 12 located in the same row or the same column can be on the same straight line, and the center connection lines of the third sub-pixel 13 located in the same column or the same row can be on the same straight line, which is beneficial to reducing the preparation difficulty of the array substrate 10 and the manufacturing difficulty of the mask plate.

[0062] Optionally, the emission colors of the first sub-pixel 11 and the second sub-pixel 12 are red and blue respectively, and the emission color of the third sub-pixel 13 is green. As described above, any third sub-pixel 13 can form two pixels with two pairs of adjacent first sub-pixels 11 and second sub-pixels 12. It is found that the green sub-pixel contributes the most to white light, and the human eye is most sensitive to green. The green sub-pixel has a high brightness and is suitable as the brightness center. By setting the third sub-pixel 13 as the green sub-pixel, it is convenient to distinguish each pixel, making the display screen perceived by the human eye more delicate and improving the display effect. The emission color of the first sub-pixel 11 is red and the emission color of the second sub-pixel 12 is blue, or the emission color of the first sub-pixel 11 is blue and the emission color of the second sub-pixel 12 is red, and the embodiments of the present invention do not limit this.

[0063] Further optionally, the emission areas of the first sub-pixel 11 and the second sub-pixel 12 are both larger than the emission area of the third sub-pixel 13. Among them, the emission area of the first sub-pixel 11 can be understood as the area of the first pixel opening 41 close to the substrate side. Similarly, the emission area of the second sub-pixel 12 can be understood as the area of the second pixel opening 42 close to the substrate side, and the emission area of the third sub-pixel 13 can be understood as the area of the third pixel opening 43 close to the substrate side. Since the human eye is sensitive to green light, the emission area of the green sub-pixel can be set to be smaller than the areas of the blue sub-pixel and the red sub-pixel to improve the resolution. For the red sub-pixel and the blue sub-pixel, their emission areas can be equal or different, and the embodiments of the present invention do not limit this. In one embodiment, since the blue light wavelength is shorter than the red light wavelength and the green light wavelength, the energy of the blue light is higher, and the organic light-emitting material emitting blue light is more likely to decay. Therefore, it is optional that the emission area of the blue sub-pixel is larger than the emission area of the red sub-pixel.
