Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

Specifically, fig. 1 is a schematic structural diagram of a first display substrate provided according to an embodiment of the present invention, as shown in fig. 1, the display substrate 1 includes an array-arranged pixel unit group 11, the pixel unit group 11 includes four pixel units 111, the shape of each pixel unit 111 is an isosceles right triangle, and in the pixel unit group 11, one pixel unit 111 is rotated by 90 °, 180 ° and 270 ° along the right-angle vertex of the isosceles right triangle, and then coincides with other pixel units 111;

the pixel unit 111 comprises three sub-pixels 1110 of different light emission colors, wherein at least two sub-pixels 1110 comprise a common vertex 2 inside an isosceles right triangle.

The pixel unit group 11 may be a basic repeating unit group of the display substrate 1, where the pixel unit group 11 includes four pixel units 111, the pixel unit group 11 is arranged in an array in the display substrate 1, and the more the number of pixel unit groups 11 in a unit area, the higher the resolution, and the clearer the image displayed in the display substrate 1.

Specifically, the pixel unit group 11 includes four pixel units 111, and since each pixel unit 111 has an isosceles right triangle shape, and one pixel unit 111 rotates 90 °, 180 ° and 270 ° along the right-angle vertex of the isosceles right triangle, and then overlaps with the other pixel units 111, the area of each sub-pixel 1110 of each light-emitting color between the four isosceles right triangle pixel units 111 is the same.

Wherein, one pixel unit group 11 translates along the isosceles right triangle hypotenuse direction of any pixel unit 111 by one hypotenuse length to coincide with other pixel unit groups 11. Due to the limitation of the display area, the pixel unit group 11 may translate along the isosceles right triangle hypotenuse direction of any pixel unit 111, where the length of one hypotenuse is partially overlapped with that of the other pixel unit groups 11. For example, as shown in fig. 1, the first pixel unit group a translates along the direction of the hypotenuse of the first isosceles right triangle by a length overlapping with the second pixel unit group B, the second pixel unit group B translates along the direction of the hypotenuse of the second isosceles right triangle by a length overlapping with one pixel unit 111 in the third pixel unit group C, and so on, the pixel unit group 11 translates along the direction of the hypotenuse of any isosceles right triangle by a length overlapping with all other pixel unit groups 11 partially or totally, so as to realize the tight arrangement of the pixel unit groups 11, and fully utilize the light emitting area, so that the aperture ratio is maximized.

It will be appreciated that, based on the array manner of the pixel unit group 11, the display substrate 1 further includes a repeating unit 112, and as shown in fig. 1, the repeating unit 112 includes a pixel unit group 11 and four pixel units 111 disposed around the pixel unit group 11, and the repeating unit 112 is square. The repeating unit 112 includes a first pixel unit B1, a second pixel unit B2, a third pixel unit B3, and a fourth pixel unit B4, and further includes a fifth pixel unit B5 overlapping the oblique side of the first pixel unit B1, a sixth pixel unit B6 overlapping the oblique side of the second pixel unit B2, a seventh pixel unit B7 overlapping the oblique side of the third pixel unit B3, and an eighth pixel unit B8 overlapping the fourth pixel unit B4. Wherein the fourth pixel unit B4 translates along the hypotenuse direction of the second pixel unit B2 by one hypotenuse length to coincide with the fifth pixel unit B5 (or the first pixel unit B1 coincides with the fifth pixel unit B5 rotationally symmetrically about the hypotenuse end point); the third pixel unit B3 translates along the hypotenuse direction of the first pixel unit B1 by one hypotenuse length to coincide with the sixth pixel unit B6; the second pixel unit B2 translates along the hypotenuse direction of the first pixel unit B1 by one hypotenuse length to coincide with the seventh pixel unit B7; the first pixel unit B1 translates along the hypotenuse direction of the second pixel unit B2 by one hypotenuse length to coincide with the eighth pixel unit B8.

Optionally, at least two sub-pixels 1110 in a single pixel unit 111 include a common vertex 2 located inside an isosceles right triangle, i.e. both sub-pixels 1110 may include a common vertex 2 located inside an isosceles right triangle, and both three sub-pixels 1110 may include a common vertex 2 located inside an isosceles right triangle.

For example, fig. 2 is a schematic structural diagram of a second display substrate provided according to an embodiment of the present invention, and fig. 3 is a schematic structural diagram of a third display substrate provided according to an embodiment of the present invention, as shown in fig. 2 and 3, in the case that two sub-pixels 1110 include a common vertex 2 located inside an isosceles right triangle, two adjacent sides of a first sub-pixel 1111 may respectively coincide with right angle sides of the isosceles triangle, a second sub-pixel 1112 and a third sub-pixel 1113 intersect at a vertex 2, and the vertex 2 is located on a side length of the first sub-pixel 1111; fig. 4 is a schematic structural view of a fourth display substrate according to an embodiment of the present invention, fig. 5 is a schematic structural view of a fifth display substrate according to an embodiment of the present invention, and fig. 6 is a schematic structural view of a sixth display substrate according to an embodiment of the present invention, as shown in fig. 4, fig. 5 and fig. 6, in which the case that three sub-pixels 1110 include a common vertex 2 located inside an isosceles right triangle may be that the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113 all intersect at a vertex 2, and the vertex 2 is located inside the isosceles right triangle. It can be understood that the purpose of defining at least two sub-pixels 1110 including the common vertex 2 located inside the isosceles right triangle in the embodiment of the present invention is that the straight edge of the repeating unit 112 in the display substrate 1 is not a single pixel, as can be seen in fig. 1, 2, 3, 4, 5 and 6, the straight edge of the repeating unit 112 formed by the pixel unit group 11 arranged in an array may include at least two sub-pixels 1110 with different light-emitting colors, so that the arrangement can improve the problem of color edges in the display substrate and enhance the display effect.

In addition, in the pixel unit group 11, one pixel unit 111 rotates 90 °, 180 ° and 270 ° along the right-angle vertex of the isosceles right triangle, and then coincides with the other pixel units 111, and the arrangement manner can make the center of the sub-pixel 1110 relatively centered in the same pixel unit group 11, so as to solve the problem of middle jaggies.

The sub-pixels 1110 with three different light-emitting colors can emit light to control the light-emitting colors, so as to form corresponding images. The sub-pixels 1110 of the color of the light commonly used in the display substrate 1 may be a red sub-pixel 1111, a green sub-pixel 1112 and a blue sub-pixel 1113.

According to the technical scheme, the pixel unit group comprises four pixel units in the shape of an isosceles right triangle, one pixel unit in the pixel unit group rotates 90 degrees, 180 degrees and 270 degrees along the right-angle vertexes of the isosceles right triangle and then is overlapped with other pixel units, and the arrangement mode can enable the sub-pixels with three different light-emitting colors to be closely arranged in the pixel unit group, so that the light-emitting area can be fully utilized, and the maximization of the aperture ratio is realized; on the other hand, at least two sub-pixels in the isosceles right triangle comprise common vertexes positioned in the isosceles right triangle, so that the pixel unit group can comprise three sub-pixels with different luminous colors in an edge area formed after the array arrangement, the problems of color edges and saw teeth in the isosceles right triangle are solved, and the display effect is improved.

Alternatively, with continued reference to fig. 1, the pixel cell group 11 has a square shape, and the row direction and the column direction of the array formed by the pixel cell group 11 are respectively parallel to two diagonal lines of the square shape.

The shape of the pixel units 111 is isosceles right triangle, and one pixel unit 111 in the pixel unit group 11 rotates 90 °, 180 ° and 270 ° along the right-angle vertex of the isosceles right triangle and then coincides with the other pixel units 111, so the shape of the pixel unit group 11 is a square formed by four isosceles right triangles, the right-angle sides of every two isosceles right triangles coincide with each other, and two diagonal lines of the square are right-angle sides of the isosceles right triangle, that is, the row direction and the column direction of the array formed by the pixel unit group 11 are parallel to the right-angle sides of the isosceles right triangle. The arrangement of the pixel unit groups 11 is more regular, so that the pixel units 111 are more favorably arranged tightly, and the display effect of high pixel density distribution is achieved.

Optionally, with continued reference to fig. 1, 2, 3, 4, and 5, the shape of at least one subpixel 1110 comprises a triangle.

In the single pixel unit 111, one triangle-shaped sub-pixel 1110 may be formed, two triangle-shaped sub-pixels 1110 may be formed, or three triangle-shaped sub-pixels 1110 may be formed, where the three sub-pixels 1110 contact each other to form an isosceles right triangle.

As shown in fig. 1 and 3, the single pixel unit 111 includes one triangle-shaped sub-pixel 1110 and two quadrangle-shaped sub-pixels 1110, wherein the three sub-pixels 1110 share a vertex, and the three sub-pixels 1110 together form an isosceles right triangle.

In addition, in this embodiment, the shape of the sub-pixels 1110 that are shown schematically as a parallelogram or trapezoid is only illustrative, and the implementation can be any quadrilateral, and only needs to ensure that three sub-pixels 1110 are densely arranged to form an isosceles right triangle.

In some embodiments, the three sub-pixels 1110 are all triangular in shape. As shown in fig. 4, the single pixel unit 111 includes three triangular sub-pixels 1110, where the three triangular sub-pixels 1110 share a vertex, and the three sub-pixels 1110 together form an isosceles right triangle. In the repeating units 112 formed by arranging the pixel unit groups 11 in an array manner, the straight sides of the repeating units 112 are parallel to the column direction of the pixel unit groups 11, and the straight sides of the repeating units 112 comprise two sub-pixels 1110 with different light-emitting colors, so that the phenomena of color edges and saw teeth are improved to a certain extent, and the display effect is improved.

It can be understood that the areas of the sub-pixels 1110 with different colors of light emission are not particularly limited in the embodiment of the present invention, and it is sufficient that the straight edge of the repeating unit 112 includes at least two sub-pixels 1110 with different colors of light emission.

Optionally, with continued reference to fig. 1, 2, 3, 5 and 6, the shape of at least one subpixel 1110 illustrated in fig. 1, 2, 3, 5 and 6 includes a quadrilateral.

Similarly, the single pixel unit 111 may also include one quadrilateral subpixel 1110, may also include two quadrilateral subpixels 1110, and may also include three quadrilateral subpixels 1110, where the three subpixels 1110 contact each other to form an isosceles right triangle.

As shown in fig. 2 and 5, the single pixel unit 111 includes one quadrangular sub-pixel 1110 and two triangular sub-pixels 1110, where the quadrangular sub-pixel 1110 and one of the triangular sub-pixels 1110 share a vertex, and the three sub-pixels 1110 together form an isosceles right triangle. In the repeating units 112 formed by arranging the pixel unit groups 11 in an array manner, the straight sides of the repeating units 112 are parallel to the column direction of the pixel unit groups 11, and the straight sides of the repeating units 112 comprise three sub-pixels 1110 with different light-emitting colors, so that the phenomena of color edges and saw teeth are improved, and the display effect is improved.

As shown in fig. 1 and 3, the single pixel unit 111 includes two quadrangular sub-pixels 1110 and one triangular sub-pixel 1110, where the three sub-pixels 1110 share a vertex, and the three sub-pixels 1110 together form an isosceles right triangle. In the repeating units 112 formed by arranging the pixel unit groups 11 in an array manner, the straight sides of the repeating units 112 are parallel to the column direction of the pixel unit groups 11, and the straight sides of the repeating units 112 comprise three sub-pixels 1110 with different light-emitting colors, so that the phenomena of color edges and saw teeth are improved, and the display effect is improved.

For example, as shown in fig. 6, the single pixel unit 111 includes three quadrilateral sub-pixels 1110, where the three quadrilateral sub-pixels 1110 share a vertex, and the three sub-pixels 1110 together form an isosceles right triangle. In the repeating units 112 formed by arranging the pixel unit groups 11 in an array manner, the straight sides of the repeating units 112 are parallel to the column direction of the pixel unit groups 11, and the straight sides of the repeating units 112 comprise three sub-pixels 1110 with different light-emitting colors, so that the phenomena of color edges and saw teeth are improved, and the display effect is improved.

With continued reference to FIG. 6, in some embodiments, the quadrilateral includes a trapezoid. Taking three quadrilateral sub-pixels 1110 as an example, the three quadrilateral sub-pixels 1110 are respectively two right-angle trapezoids and an isosceles trapezoid, the right-angle sides of the two right-angle trapezoids are respectively overlapped with the right-angle sides of the isosceles triangle, and the three sub-pixels 1110 share a vertex and form the isosceles right triangle. In the repeating units 112 formed by arranging the pixel unit groups 11 in an array manner, the straight sides of the repeating units 112 are parallel to the column direction of the pixel unit groups 11, and the straight sides of the repeating units 112 comprise three sub-pixels 1110 with different light-emitting colors, so that the phenomena of color edges and saw teeth are improved, and the display effect is improved.

Alternatively, the three sub-pixels 1110 are polygonal in shape, and the three sub-pixels 1110 include a common vertex 2 located inside an isosceles right triangle.

The polygon may be a quadrangle, a pentagon, or other polygons, and the three polygon sub-pixels 1110 together form an isosceles right triangle. The three sub-pixels 1110 may be shaped as a quadrangle in consideration of ease of implementation in the process.

Similarly, as shown in fig. 6, taking a quadrangle as an example, three quadrangle sub-pixels 1110 together form an isosceles right triangle, wherein the sides of two quadrangle sub-pixels 1110 respectively coincide with the right-angle sides of the isosceles triangle, and the three sub-pixels 1110 share a vertex and form the isosceles right triangle.

Alternatively, with continued reference to FIG. 4, the areas of the three sub-pixels 1110 are equal.

Since the single pixel unit 111 includes the three sub-pixels 1110 with different light-emitting colors, the same area of the three sub-pixels 1110 is defined, so that the total distribution areas of the sub-pixels 1110 with different light-emitting colors are the same, the images are more uniform when the three sub-pixels 1110 with different light-emitting colors emit light, and the display effect is improved.

It is to be understood that the pixel arrangement mode in which the areas of the three sub-pixels 1110 are equal in the embodiment of the present invention can be applied to the field of organic light emitting diode display and the field of liquid crystal display, and the embodiment of the present invention is not limited by the comparison.

Since the red sub-pixel 1111, the green sub-pixel 1112 and the blue sub-pixel 1113 have different service lives and efficiencies of luminescent materials, especially the service lives and the efficiencies of the blue sub-pixel 1113 are smaller than those of the red sub-pixel 1111 and the green sub-pixel 1112, and display brightness is reduced in advance in the display process, setting the area of the blue sub-pixel 1113 to be larger than that of the red sub-pixel 1111 and that of the green sub-pixel 1112 can enable the red sub-pixel 1111, the green sub-pixel 1112 and the blue sub-pixel 1113 to obtain similar service lives and efficiencies in area so as to maintain normal display, and the overall display life is increased.

In addition, since the human eye is sensitive to green light, the center of the green sub-pixel 1112 in the pixel unit 11 is relatively centered to improve the jaggy problem, further improving the display effect.
