In the pixel unit 15, the third color pixel B includes a first sub-pixel section B1 and a second sub-pixel section B2, and the first sub-pixel section B1 and the second sub-pixel section B2 are symmetrical along the first symmetry axis DL. The first sub-pixel section B1 and the second sub-pixel section B2 are symmetrical along the first symmetry axis DL. The first color pixel R and the first sub-pixel portion B1 have the same shape and size, and the second color pixel G and the second sub-pixel portion B2 have the same shape and size, that is, the first color pixel R and the second color pixel G can be spliced along the longest side to form the same structure as the third color pixel B. The bottom edges of the first color pixel R and the second color pixel G are arranged in parallel and adjacent to each other, and can be spliced into a square with the same area as the third color pixel B.
Referring to fig. 12, fig. 12 is a schematic view showing another arrangement of the pixels in fig. 10. As shown in fig. 12, in the display region 13a of the display panel 13, a plurality of pixel units 15 are included, and in a row of the pixel units 15 arranged consecutively, the first color pixels R or the second color pixels G in two adjacent pixel units 15 are arranged adjacently and have parallel bases, that is, the first color pixels R in two adjacent pixel units 15 may be spliced into the first color pixels R in a diamond shape or a square shape or the second color pixels G in two adjacent pixel units 15 may be spliced into the second color pixels G in a square shape. For example, in the first pixel unit 15a and the second pixel unit 15b which are adjacently arranged, the bottom side of the first color pixel R in the first pixel unit 15a and the bottom side of the first color pixel R in the second pixel unit 15b are adjacently arranged in parallel, and are jointly spliced to form the first color pixel R in a square shape. In the first pixel unit 15a and the third pixel unit 15c which are adjacently arranged, the bottom side of the second color pixel G in the first pixel unit 15a and the bottom side of the second color pixel G in the third pixel unit 15c are adjacently arranged in parallel, and are jointly spliced to form the second color pixel G in a square shape. By adjacently arranging the same-color sub-pixels of the adjacent pixel units, the same-color sub-pixels of the adjacent pixel units 15 can share one mask plate opening during pixel evaporation, so that the number and the size precision of the openings of the mask plate can be greatly reduced, the precision requirement during pixel evaporation can be reduced, and the production yield is improved; because the preparation difficulty is reduced, a display panel with higher resolution can be manufactured, and the resolution of the display panel is improved.
Referring to fig. 13, fig. 13 is another structural diagram of the pixel unit in fig. 10. As shown in fig. 12, the display region 13a includes a plurality of first color pixels R, a plurality of second color pixels G, and a plurality of third color pixels B, the first color pixels R and the second color pixels G have equal areas, and the area of the third color pixels B is twice the area of the first color pixels R or the second color pixels G, that is, the sum of the areas of the first color pixels R and the second color pixels G is equal to the area of the third color pixels B. The first color pixel R and the second color pixel G are isosceles right triangles, and the third color pixel B is a square. The first color pixel R and the second color pixel G may be spliced into a square having the same size as the third color pixel B along the bottom edge.
The pixel unit 15 is a rectangular structure, the first color pixel R and the second color pixel G are parallel and closely adjacent to each other along the bottom side, and one side edge of the third color pixel B is parallel and closely adjacent to one side edge of the first color pixel R or the second color pixel G, so as to form the rectangular pixel unit 15.
Through the setting of the shield-shaped pixel unit, the light-emitting area of the third color pixel B, namely the blue pixel, in the pixel unit is increased, so that the current density flowing through the unit area of the blue pixel is reduced, the service life of the blue pixel is prolonged, and meanwhile, the ratio of the number of the first color pixel R, the second color pixel G and the third color pixel B in the pixel unit 15 is 1. Meanwhile, the shape formed by splicing the first color pixel R and the second color pixel G is the same as that of the third color pixel B, namely, the shape is a rhombus or a square, so that when the pixels are arranged, the three pixels can be spliced completely, and the space utilization rate of the display panel is greatly improved.
Through making first color pixel R or the adjacent setting of second color pixel G in adjacent pixel cell 15 for pixel cell can promote production efficiency, reduce cost, reduces the machining precision of pixel production, improves the production yield with the adjacent pixel of the same colour of arranging in the manufacture process.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
