[0002] In the prior art, a plurality of color sub-pixels, such as red sub-pixels, green sub-pixels and blue sub-pixels, are usually used in a pixel structure to construct a corresponding repeating unit, and a plurality of repeating units are arranged to form the arrangement of pixels in the display area of the pixel structure.

[0003] The defect of the prior art is that there is a certain non-display area between the plurality of sub-pixels constituting the repeating unit. This part of the non-display area is not covered by any sub-pixel, so it cannot perform any display operation. Due to the existence of this part of the non-display area, the area of the region between the sub-pixels without sub-pixels is large, which leads to low utilization rate of the pixel arrangement area of the pixel structure, thereby resulting in low pixel density of the pixel structure.

[0033] 5The application will be described in further detail below in connection with the accompanying drawings and embodiments. It is to be specifically pointed out that the following embodiments are only used to illustrate the application, but do not limit the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, but not all the embodiments of the application. All other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0034] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with other embodiments.

[0035] In the description of the application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, it can be detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or connected through an intermediate medium. For those skilled in the art, the above can be specifically connected according to the specific meaning of the application.

[0036] The application first proposes a pixel structure, as shown in Figure 1 and 2 , Figure 1 is one of the structure schematic diagrams of an embodiment of the pixel structure of the application, Figure 2 is one of the structure schematic diagrams of an embodiment of the repeating unit of the application, as shown in Figure 1 and 2 The pixel structure includes a plurality of repeating units, and each repeating unit includes a first sub-pixel 11, a second sub-pixel 12 and a third sub-pixel 13. The shape of the second sub-pixel 12 is congruent to the shape of the third sub-pixel 13. The shape of the first sub-pixel 11 is different from the shape of the second sub-pixel 12. The shape of the first sub-pixel 11 is a multi-angle star shape, and the number of angles of the multi-angle star shape is greater than or equal to three.

[0037] In a single repeating unit, as shown in Figure 2 The geometric center of the shape of the second sub-pixel 12 and the geometric center of the shape of the third sub-pixel 13 are located on the same line. Specifically, since the second sub-pixel 12 is congruent to the third sub-pixel 13, the second sub-pixel 12 and the third sub-pixel 13 completely overlap in the row direction.

[0038] The geometric center of the shape of the first sub-pixel 11, the geometric center of the shape of the second sub-pixel 12 and the geometric center of the shape of the third sub-pixel 13 are connected to form an isosceles triangle, and the distance between the geometric center of the shape of the first sub-pixel 11 and the geometric center of the shape of the second sub-pixel 12 and the geometric center of the shape of the third sub-pixel 13 is equal. Specifically, as shown in Figure 2 , the geometric center corresponding to the first sub-pixel 11, the geometric center corresponding to the second sub-pixel 12 and the geometric center corresponding to the third sub-pixel 13 are connected to form an isosceles triangle A.

[0039] At least part of the first sub-pixel 11 overlaps the second sub-pixel 12 in the row direction, and at least part of the first sub-pixel 11 is located between the second sub-pixel 12 and the third sub-pixel 13. Specifically, as shown in Figure 2 , the partial region B of the first sub-pixel 11 is located between the second sub-pixel 12 and the third sub-pixel 13, and the partial region B overlaps the second sub-pixel 12 in the row direction D1, or the partial region B overlaps the third sub-pixel 13 in the row direction D1.

[0040] Based on the above manner, at least part of the first sub-pixel 11, for example, the part of the first sub-pixel 11 corresponding to the partial region B, can fill the gap between the second sub-pixel 12 and the third sub-pixel 13 without any pixels or partial pixels, thereby reducing the non-display area existing in the gap between the sub-pixels in the repeating unit, improving the utilization rate of the pixel arrangement area in the pixel structure, and further improving the pixel density of the pixel structure.

[0041] For example, the above-mentioned multi-angle star can be a triangular star or a regular triangular star, as shown in Figure 8 (A), the shape of the first sub-pixel 11 in the repeating unit can be a regular triangular star, as shown in Figure 8 (B), the shape of the first sub-pixel 11 in the repeating unit can be a triangular star, and a plurality of repeating units can form a pixel arrangement as shown in Figure 9 (A) or (B).

[0042] The above-mentioned multi-angle star can also be an octagonal star or a regular octagonal star, as shown in Figure 10 , the shape of the first sub-pixel 11 in the repeating unit can be an octagonal star or a regular octagonal star, and a plurality of repeating units can form a pixel arrangement as shown in Figure 11 .

[0043] It should be noted that the above is only an example, and the multi-angle star can also be one of other multi-angle stars, such as a four-angle star, a five-angle star, a seven-angle star, and other multi-angle stars, and the specific number of angles can be determined according to actual needs, which is not limited here. In addition, the shapes of the second sub-pixel 12 and the third sub-pixel 13 can be one of a circle, an ellipse, a rhombus, a polygon, and other arbitrary shapes, and the specific shape can be determined according to actual needs, which is not limited here.

[0044] In the technical solution of the present application, unlike the prior art, a plurality of repeating units are arranged in the pixel structure, each repeating unit includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, wherein the shapes of the second sub-pixel and the third sub-pixel are congruent, the shape of the first sub-pixel is different from the shape of the second sub-pixel, the shape of the first sub-pixel is a multi-angle star, the number of angles of the multi-angle star is greater than or equal to three, and in the same repeating unit, the geometric centers corresponding to the second sub-pixel and the third sub-pixel are located in the same row, and the geometric centers corresponding to the first sub-pixel, the second sub-pixel, and the third sub-pixel form an isosceles triangle, at least part of the first sub-pixels between the second sub-pixel and the third sub-pixel overlap with the second sub-pixel or the third sub-pixel in the row direction. Based on the above manner, the first sub-pixel can fill the gap between the second sub-pixel and the third sub-pixel in the same repeating unit, thereby reducing the non-display area of the sub-pixel piece, improving the utilization rate of the pixel arrangement area of the pixel structure, and further improving the pixel density of the pixel structure.

[0045] In addition, the arrangement manner adopted in the technical solution of the present application is a non-Pentile arrangement manner, that is, each repeating unit is composed of three sub-pixels, and there is no case of two repeating units sharing one sub-pixel, so that the pixel independence is high, and when the display device in which the pixel structure is located displays a complex image, the graininess caused by the absence of sub-pixels can be avoided, and the interference between the sub-pixels of adjacent repeating units can also be avoided. In summary, arranging pixels based on the arrangement manner of the present application can reduce image crosstalk problems and improve the display clarity of the display device.

[0046] In an embodiment, the geometric centers of the shape of the first sub-pixel 11, the geometric centers of the shape of the second sub-pixel 12, and the geometric centers of the shape of the third sub-pixel 13 form an equilateral triangle, the shape of the first sub-pixel 11 is a regular hexagonal star, and at least part of the first sub-pixel 11 includes a sub-pixel part corresponding to a corner region of the regular hexagonal star. The sub-pixel part corresponding to the corner region can be part of the first sub-pixel 11 corresponding to the corner region.

[0047] Specifically, as shown in Figure 1 and Figure 2As shown, the shape of the first sub-pixel 11 is a regular hexagonal star, and the geometric center corresponding to the first sub-pixel 11 is the origin. There is an angular region every 60 degrees, and there are six angular regions in a regular hexagonal star. The partial region B corresponding to at least part of the first sub-pixel 11 can be an angular region of the regular hexagonal star-shaped first sub-pixel 11.

[0048] Based on the above manner, the repeating unit with the first sub-pixel 11 of the regular hexagonal star shape can be repeatedly arranged to form a pixel structure with a pixel arrangement as shown in Figure 1 The pixel structure with the pixel arrangement as shown can reduce the non-display region between the sub-pixels, improve the utilization rate of the pixel arrangement region of the pixel structure, and further improve the pixel density of the pixel structure.

[0049] Optionally, the plurality of repeating units are arranged in multiple columns, and each column of repeating units includes a plurality of repeating units arranged in sequence along the column direction.

[0050] Specifically, in the pixel arrangement as shown in Figure 1 Three columns of repeating units are arranged in sequence along the row direction D1, and each column of repeating units includes a plurality of repeating units arranged in sequence along the column direction D2. The row direction D1 and the column direction D2 are perpendicular to each other.

[0051] Since the connecting line of the geometric center corresponding to the first sub-pixel 11, the geometric center corresponding to the second sub-pixel 12, and the geometric center corresponding to the third sub-pixel 13 forms an equilateral triangle, and the shape of the first sub-pixel 11 in the repeating unit is a regular hexagonal star, each angular region of the first sub-pixel 11 can be located between the corresponding two second sub-pixels 12 and third sub-pixels 13. The two second sub-pixels 12 and third sub-pixels 13 can be sub-pixels in the same repeating unit or sub-pixels in different repeating units, which is determined by the relative position of the corresponding angular region in the first sub-pixel 11.

[0052] Based on the above manner, each angular region of the first sub-pixel 11 can fill the gap between the corresponding sub-pixels, thereby reducing the non-display region in the repeating unit due to the gap between the sub-pixels, improving the utilization rate of the pixel arrangement region in the pixel structure, and further improving the pixel density of the pixel structure.

[0053] Further, in the two adjacent columns of repeating units, any repeating unit in one column of repeating units partially overlaps with the corresponding repeating unit in the other column of repeating units in the row direction.

[0054] Specifically, as shown in Figure 1 In the multiple columns of repeating units, there are no two repeating units respectively located in the two columns of repeating units and completely overlapping in the row direction D1, so that the repeating units can form a pixel arrangement as shown inFigure 1 The staggered arrangement shown improves the jagged effect present in the pixels, thereby improving the display effect of the pixel structure.

[0055] Further, one of the plurality of repeating units is taken as a target repeating unit, and six repeating units adjacent to the target repeating unit are taken as edge repeating units.

[0056] The geometric centers of the shapes of all the edge repeating units are connected to form a first target regular hexagon, and the geometric center of the shape of the target repeating unit overlaps the geometric center of the first target regular hexagon.

[0057] Based on the above manner, the seven adjacent repeating units can be arranged in the same direction and at the geometric center and six corner points of the first target regular hexagon, so that the six corner regions of the first sub-pixel 11 of the target repeating unit can accurately and appropriately fill the gap between the corresponding two repeating units or two sub-pixels, further reducing the non-display area between the repeating units due to the gap between the sub-pixels, improving the utilization rate of the pixel arrangement area in the pixel structure, and further improving the pixel density of the pixel structure.

[0058] Specifically, as shown in the figure, Figure 1 The first sub-pixel 11 in the target repeating unit X is taken as a target first sub-pixel, and the first sub-pixel 11 in the six edge repeating units Y adjacent to the target repeating unit X is taken as an edge target first sub-pixel.

[0059] The geometric centers of the shapes of all the edge target first sub-pixels are connected to form a second target regular hexagon Z, and the geometric center of the shape of the target first sub-pixel in the target repeating unit X overlaps the geometric center of the second target regular hexagon Z.

[0060] Based on the above manner, the position of each corner region of the target first sub-pixel in the target repeating unit X can be further ensured to match the position of the gap between the corresponding two sub-pixels, thereby forming the most effective gap filling, minimizing the area of the non-display area between the sub-pixels in the repeating unit, improving the utilization rate of the pixel arrangement area in the pixel structure, and further improving the pixel density of the pixel structure.

[0061] In addition, in the target repeating unit X and the six edge repeating units Y adjacent thereto, all the second sub-pixels 12 and / or all the third sub-pixels 13 can also have a relationship corresponding to all the first sub-pixels 11 described above, which is as follows:

[0062] Regarding the second sub-pixel 12, the second sub-pixel 12 in the target repeating unit is taken as a target second sub-pixel 12, the second sub-pixel 12 in the edge repeating unit is taken as an edge second sub-pixel 12, and the geometric centers of the shapes of all the edge second sub-pixels 12 are connected to form a third target regular hexagon, and the geometric center of the shape of the target second sub-pixel 12 overlaps the geometric center of the third target regular hexagon.

[0063] Regarding the third sub-pixel 13, the third sub-pixel 13 in the target repeating unit is taken as a target third sub-pixel 13, the third sub-pixel 13 in the edge repeating unit is taken as an edge third sub-pixel 13, and the geometric centers of the shapes of all the edge third sub-pixels 13 are connected to form a fourth target regular hexagon, and the geometric center of the shape of the target third sub-pixel 13 overlaps the geometric center of the fourth target regular hexagon.

[0064] The third target regular hexagon and the fourth target regular hexagon are both the same shape as the second target regular hexagon.

[0065] Optionally, the area of the shape of the first sub-pixel 11 is greater than the area of the shape of the second sub-pixel 12, the colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different, the first sub-pixel 11 is a blue sub-pixel, and / or the shape of the second sub-pixel 12 is a regular hexagon or a regular circle.

[0066] Specifically, the area corresponding to the display region of the first sub-pixel 11 can be greater than the area corresponding to the display region of the second sub-pixel 12 or the third sub-pixel 13, and the first sub-pixel 11 can be a blue sub-pixel, and the second sub-pixel 12 and the third sub-pixel 13 are red sub-pixels and green sub-pixels, respectively. Based on the above manner, the first sub-pixel 11 with a larger area can have higher light-emitting efficiency, thereby improving the service life of the corresponding organic light-emitting material, and further improving the service life of the pixel structure.

[0067] As shown in Figure 1 and 2 , the shapes of the second sub-pixel 12 and the third sub-pixel 13 can be regular hexagons, as shown in Figure 3 and 4 , the shapes of the second sub-pixel 12 and the third sub-pixel 13 can be regular circles, in addition, the shapes of the second sub-pixel 12 and the third sub-pixel 13 can also be other shapes without sharp display region edges, which are not limited here. Based on the above manner, since the display region edges of the second sub-pixel 12 and the third sub-pixel 13 do not have sharp angles but only have obtuse angles, the jaggedness of the pixel structure is reduced, and the display effect of the pixel structure is improved.

[0068] Optionally, the geometric center line connecting the shapes of three adjacent first sub-pixels 11 forms an equilateral triangle, and / or, the geometric center line connecting the shapes of three adjacent second sub-pixels 12 forms an equilateral triangle, and / or, the geometric center line connecting the shapes of three adjacent third sub-pixels 13 forms an equilateral triangle.

[0069] Specifically, by making the line connecting the geometric centers of three sub-pixels in the same repeating unit form an equilateral triangle, and by making the line connecting the geometric centers of three adjacent sub-pixels of the same type in multiple repeating units form an equilateral triangle, the compactness of the arrangement between repeating units can be improved, the area of ​​the gaps can be reduced, and the utilization rate of the pixel arrangement area can be improved, thereby increasing the pixel density.

[0070] For example, the first sub-pixel can be a blue sub-pixel, while the second and third sub-pixels can correspond one-to-one with the red and green sub-pixels. The three sub-pixels can also be other color combinations, which are not limited here.

[0071] like Figure 13 As shown, the first sub-pixel is a regular hexagon of size one with twelve sides. The second and third sub-pixels are both regular circles of size two. B is the centroid of the first sub-pixel, R is the centroid of the second sub-pixel, and G is the centroid of the third sub-pixel.

[0072] The ends of the repeating unit are... Figure 13 In the dashed box shown, the second sub-pixel is tangent to the left and bottom ends of the repeating unit, respectively, and the third sub-pixel is tangent to the right and bottom ends of the repeating unit, respectively. Figure 13 The dashed box shown is a square with a side length of m.

[0073] The centroid of the first sub-pixel is 3 / 8 of the distance from the top of the repeating unit to the centroid of the first sub-pixel. The centroid of the first sub-pixel is located on the center line of the repeating unit extending along the second direction D2 in the first direction D1.

[0074] The length of the first sub-pixel in the first direction D1 is 3 / 4 of n, the length of the first sub-pixel in the second direction D2 is 3 / 4 of m, the distance from the centroid of the first sub-pixel to each corner point is equal, and the distance is 3 / 8 of m, and the distance from the centroid of the first sub-pixel to the left and right ends of the repeating unit is equal.

[0075] The circular diameter of the second sub-pixel is 3 / 8 of m. The distance from the centroid of the second sub-pixel to the left and bottom ends of the repeating unit is 3 / 16 of m. The distance from the centroid of the second sub-pixel to the top and right ends of the repeating unit is 13 / 16 of m.

[0076] The circular diameter of the third sub-pixel is 3 / 8 of m, the distance from the centroid of the second sub-pixel to the right end and the lower end of the repeating unit is 3 / 16 of m, and the distance from the centroid of the second sub-pixel to the top end and the left end of the repeating unit is 13 / 16 of m.

[0077] The centroid of the second sub-pixel and the centroid of the third sub-pixel are located on a straight line extending along the first direction D1, the distance from the centroid of the second sub-pixel to the centroid of the third sub-pixel is 5 / 8 of m, the centroid of the first sub-pixel is located on the perpendicular bisector of the line segment RG, and the distance from the centroid of the first sub-pixel to the line segment RG is 9 / 16 of m.

[0078] The repeating units are arranged in columns along the second direction D2, a plurality of repeating units are arranged in a plurality of columns, and the adjacent two columns of repeating units are arranged in a staggered manner along the second direction D2, and in the adjacent two columns of repeating units, the centroid of a first sub-pixel in one column of repeating units is located on the same straight line as the centroid of a second sub-pixel / third sub-pixel in another column of repeating units along the first direction D1.

[0079] In the same column of repeating units, the centroids of the sub-pixels of the same type are located on the same straight line extending along the second direction D2.

[0080] Optionally, the second sub-pixel 12 and the third sub-pixel 13 are two types of sub-pixels formed by evaporation using the same mask plate.

[0081] Specifically, taking the pixel structure shown in Figure 1 as an example, when the shape of the first sub-pixel 11 is a hexagon and the shape of the second sub-pixel 12 is a regular hexagon, referring to Figure 5 and 6 , Figure 5 is a structural schematic diagram of an embodiment of the first mask plate of the present application, Figure 6 is a structural schematic diagram of an embodiment of the second mask plate of the present application, as shown in Figure 5 and 6 , the first mask plate containing a plurality of first openings M shown in Figure 5 may be used for evaporation to simultaneously generate a plurality of first sub-pixels 11, and the second mask plate shown in Figure 6The second mask, which contains multiple second openings N, is used for vapor deposition to simultaneously generate multiple second sub-pixels 12. Since the relative positional relationship between multiple adjacent second sub-pixels 12 is the same as the relative positional relationship between multiple adjacent third sub-pixels 13, multiple third sub-pixels 13 can be generated simultaneously by moving and / or rotating the second mask to the generation position corresponding to the third sub-pixel 13 and performing vapor deposition. That is, by using the same mask, vapor deposition is performed separately to generate multiple second sub-pixels 12 and multiple third sub-pixels 13, thereby reducing the construction of one mask and enabling the vapor deposition generation of three types of sub-pixels through two types of masks, reducing the time and cost of pixel structure.

[0082] It should be noted that the above is only an example. In practice, the first sub-pixel 11 and the second sub-pixel 12 can also be other shapes, which are not limited here.

[0083] In one embodiment, in a repeating unit, the line connecting the geometric center of the shape of the first sub-pixel 11 and the geometric center of the shape of the second sub-pixel 12 is designated as a first connecting line, the line connecting the geometric center of the shape of the first sub-pixel 11 and the geometric center of the shape of the third sub-pixel 13 is designated as a second connecting line, the intersection of the first connecting line and the edge of the second sub-pixel 12 is designated as a first intersection point, the intersection of the second connecting line and the edge of the third sub-pixel 13 is designated as a second intersection point, and the line connecting the first intersection point and the second intersection point is designated as a third connecting line. The distance between the third connecting line and the geometric center of the shape of the first sub-pixel 11 is less than the distance between the apex corner of the shape of the first sub-pixel 11 and the geometric center of the shape of the first sub-pixel 11.

[0084] Specifically, such as Figure 12 As shown, the distance between the third line and the geometric center of the shape of the first sub-pixel 11 can specifically refer to the distance D1, while the distance between the apex of the shape of the first sub-pixel 11 and the geometric center of the shape of the first sub-pixel 11 can specifically refer to D2, where D1 is less than D2.

[0085] Based on the above method, the portion of the first sub-pixel 11 in the same repeating unit located between the second sub-pixel 12 and the third sub-pixel 13 is sufficient, further reducing the non-display area existing due to the gap between factor pixels between repeating units, improving the utilization rate of the pixel arrangement area in the pixel structure, and thus improving the pixel density of the pixel structure.

[0086] This application also proposes a display panel, see [link to relevant documentation] Figure 7 , Figure 7 This is a schematic diagram of the structure of one embodiment of the display panel of this application, as shown below. Figure 7As shown, the display panel 20 includes a power module 21 and a pixel structure 22, which can be the pixel structure described in any of the foregoing embodiments and will not be repeated here.

[0087] Different from the prior art, in the technical solution of the present application, a plurality of repeating units are arranged in the pixel structure, each of the repeating units includes a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein the second sub-pixel is congruent with the third sub-pixel in shape, the first sub-pixel is different from the second sub-pixel in shape, the shape of the first sub-pixel is a multi-angle star shape, the number of angles of the multi-angle star shape is greater than or equal to three, and in the same repeating unit, the geometric center corresponding to the second sub-pixel and the geometric center corresponding to the third sub-pixel are located in the same row, and the geometric centers corresponding to the first sub-pixel, the second sub-pixel and the third sub-pixel form an isosceles triangle, at least part of the first sub-pixels between the second sub-pixel and the third sub-pixel overlap with the second sub-pixel or the third sub-pixel in the row direction, based on the above manner, the first sub-pixel can fill the gap between the second sub-pixel and the third sub-pixel in the same repeating unit, thereby reducing the non-display area of the sub-pixel piece, improving the utilization rate of the pixel arrangement area of the pixel structure, and further improving the pixel density of the pixel structure.
