the three color sub-pixels 10 are respectively a first color sub-pixel 11, a second color sub-pixel 12 and a third color sub-pixel 13; the connecting line of the center of the first color sub-pixel 11, the center of the second color sub-pixel 12 and the center of the third color sub-pixel 13 is a triangle;
the plurality of pixels 10 includes a first pixel P1, a second pixel P2, a third pixel P3, and a fourth pixel P4.
In the first pixel P1, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the second direction Y, the first color sub-pixel 11 is disposed on the first side 101 of the second color sub-pixel 12, and a connection line L1 between the center of the first color sub-pixel 11 and the center of the second color sub-pixel 12 is located on the third side 103 of the third color sub-pixel 13;
in the second pixel P2, the second color sub-pixel 12 and the third color sub-pixel 13 are arranged along the second direction Y, the second color sub-pixel 12 is disposed on the first side 101 of the third color sub-pixel 13, and the line L2 connecting the center of the second color sub-pixel 12 and the center of the third color sub-pixel 13 is located on the fourth side 104 of the first color sub-pixel 11;
in the third pixel P3, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the second direction Y, and the second color sub-pixel 12 is disposed on the first side 101 of the first color sub-pixel 11, and the line L3 connecting the center of the first color sub-pixel 11 and the center of the second color sub-pixel 12 is located on the fourth side 104 of the third color sub-pixel 13;
in the fourth pixel P4, the second color sub-pixel 12 and the third color sub-pixel 13 are arranged along the second direction Y, the third color sub-pixel 13 is disposed on the first side 101 of the second color sub-pixel 12, and a line L4 connecting the center of the second color sub-pixel 12 and the center of the third color sub-pixel 13 is located on the third side 103 of the first color sub-pixel 11.
The array substrate includes first pixel rows P10 and second pixel rows P20 alternately arranged along the second direction Y; the first pixel row P10 includes first and second pixels P1 and P2 alternately arranged in the first direction X, and the second pixel row P20 includes third and fourth pixels P3 and P4 alternately arranged in the first direction X.
In the array substrate provided by this embodiment, the display area AA can display image information, and the non-display area BB can be provided with structures such as traces and electronic elements.
The display area AA includes a plurality of pixels P, and the pixels P include three color sub-pixels 10, and the embodiment does not limit the specific color of the sub-pixels 10. In the array substrate provided in this embodiment, the sub-pixels 10 in the pixel P are arranged in a triangle. Specifically, a line connecting the center of the first color sub-pixel 11, the center of the second color sub-pixel 12, and the center of the third color sub-pixel 13 is a triangle TR. The triangle TR may be an isosceles triangle, an equilateral triangle, or other types of triangles, and the embodiment is not limited in this respect. It should be noted that the center of the sub-pixel may be the symmetric center of the sub-pixel, for example, if the sub-pixel 10 shown in fig. 2 is a rectangle, the center of the sub-pixel is the intersection of the diagonals of the rectangle.
Because the sub-pixels 10 in the pixels P are arranged in a triangular shape, the sub-pixels 10 of the plurality of pixels P can be arranged in a staggered manner, when a pixel rendering technology is applied, the sub-pixels of one color can use the sub-pixels of other adjacent colors, the pixel rendering technology is favorably realized, and the resolution of the array substrate is improved in the display effect.
The plurality of pixels 10 includes a first pixel P1, a second pixel P2, a third pixel P3, and a fourth pixel P4. The relative positional relationship of the sub-pixels 10 of the three colors differs for any two of the first pixel P1, the second pixel P2, the third pixel P3, and the fourth pixel P4.
For clarity of description of the relative positional relationship between the sub-pixels 10, each sub-pixel 10 includes first and second sides 101 and 102 disposed oppositely, and third and fourth sides 103 and 104 disposed oppositely, the first and second sides 101 and 102 being arranged along the first direction X, and the third and fourth sides 103 and 104 being arranged along the second direction Y.
In this embodiment, the sub-pixels 10 in the pixel P are arranged in a triangle, and each of the first pixel P1, the second pixel P2, the third pixel P3 and the fourth pixel P4 includes two sub-pixels 10 arranged along the second direction Y. For example, in the first pixel P1, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged in the second direction Y. Therefore, in the present embodiment, although three sub-pixels 10 are included in one pixel P, one pixel P occupies only the space of two columns of sub-pixels, thereby facilitating the arrangement of the sub-pixels at a larger interval in the first direction X. In some optional implementation manners, the array substrate provided by the embodiment is suitable for the technical field of organic light emitting display, and when a corresponding metal mask is manufactured, the distance between adjacent openings in the metal mask corresponding to the sub-pixels can be relatively large, so that the strength of the metal mask is increased, the manufacture of the small-sized sub-pixels is facilitated, and the resolution of the array substrate can be further improved.
It should be noted that, in this embodiment, the connection line of the centers of the sub-pixels does not actually exist in the real substrate, but is artificially illustrated in the schematic structural diagram of the array substrate in order to describe the technical solution of this embodiment.
The array substrate provided in this embodiment may be applicable to the technical field of liquid crystal display, and may also be applicable to the technical field of organic light emitting display, and this embodiment does not specifically limit this.
In the array substrate provided by this embodiment, the sub-pixels of three colors in the array substrate are regularly staggered and tightly arranged, which is beneficial to applying a pixel rendering technology and improving the resolution of the array substrate in the display effect.
In some alternative embodiments, referring to fig. 3, the array substrate includes first pixel columns P01 and second pixel columns P02 alternately arranged along a first direction X; the first pixel column P01 includes first and third pixels P1 and P3 alternately arranged in the second direction Y, and the second pixel column P02 includes second and fourth pixels P2 and P4 alternately arranged in the second direction Y. In the array substrate provided by this embodiment, the first pixels P1 and the third pixels P3 are alternately arranged along the second direction Y, and the second pixels P2 and the fourth pixels P4 are alternately arranged along the second direction Y, which is beneficial to the close arrangement of the plurality of pixels P in the array substrate and the provision of a high-resolution array substrate.
In some alternative embodiments, as shown in fig. 4, the length of the sub-pixel along the second direction Y is d 1; the first pixel column P01 includes a plurality of first pixel groups P11, and the first pixel group P11 includes adjacent one first pixel P1 and one third pixel P3; in the first pixel group P11, the second color sub-pixel 12 of the first pixel P1 is located at the first side 101 of the third color sub-pixel 13 of the third pixel P3; wherein, along the second direction Y, the distance between the center of the second color sub-pixel 12 of the first pixel P1 and the center of the second color sub-pixel 12 of the third pixel P3 is d 1/2. In the array substrate provided by this embodiment, in the first pixel group P11, the distance between the centers of the second color sub-pixels 12 of two adjacent pixels P along the second direction Y is d 1/2. The distance between the centers of the second color sub-pixels 12 of the two adjacent pixels P along the second direction Y is not suitable to be too large, and if the distance is too large, the arrangement of the pixels P is loose, which is not favorable for providing a high-resolution array substrate; the distance between the centers of the second color sub-pixels 12 of the two adjacent pixels P along the second direction Y should not be too small, and if it is too small, the distance between the pixels P is too close, which is high in requirement for the manufacturing process of the array substrate, and is not beneficial to the manufacturing of the array substrate. The technical scheme of the embodiment is beneficial to the close arrangement of a plurality of pixels P in the array substrate and the provision of the array substrate with high resolution.
In some alternative embodiments, the second pixel column P02 includes a plurality of second pixel groups P22, and the second pixel group P22 includes two adjacent second pixels P2 and a fourth pixel P4; in the second pixel group P22, the first color sub-pixel 11 of the second pixel P2 is located at the first side 101 of the third color sub-pixel 13 of the fourth pixel P4; wherein, along the second direction Y, the distance between the center of the third color sub-pixel 13 of the second pixel P2 and the center of the third color sub-pixel 13 of the fourth pixel P4 is d 1/2. In the array substrate provided in this embodiment, in the second pixel group P22, the distance between the centers of the third color sub-pixels 13 of two adjacent pixels P along the second direction Y is d 1/2. The distance between the centers of the third color sub-pixels 13 of the two adjacent pixels P along the second direction Y is not suitable to be too large, and if the distance is too large, the arrangement of the pixels P is loose, which is not favorable for providing a high-resolution array substrate; the distance between the centers of the third color sub-pixels 13 of the two adjacent pixels P along the second direction Y should not be too small, and if the distance is too small, the distance between the pixels P is too close, which is high in the requirement of the manufacturing process of the array substrate, and is not beneficial to the manufacturing of the array substrate. The technical scheme of the embodiment is beneficial to the close arrangement of a plurality of pixels P in the array substrate and the provision of the array substrate with high resolution.
