According to the display base plate that the utility model at least embodiment provides, in the pixel arrangement structure of display base plate,
Reduce the distance between the first sub-pixel and the 4th sub-pixel in same pixel groups, on the one hand, may make pixel arrangement more
Closely, it reduces colour mixture risk, improve color side, improve vision granular sensation.On the other hand, the spacing between sub-pixel can be widened, with
Conducive to making.Alternatively, the spacing between pixel arrangement tightness degree and sub-pixel can also be taken into account, seek one between
Balance so that pixel arrangement relative close and the spacing between sub-pixel (pixel definition interlamellar spacing) is widened to a certain extent, with
Colour mixture risk, the color side of improvement are reduced conducive to getting both, improves the effect of vision granular sensation and widens the spacing between sub-pixel
Effect.For example, the shape of each sub-pixel provided in the embodiments of the present invention can be defined by pixel defining layer, but it is not limited to
This.For example, each sub-pixel in attached drawing is practical light-emitting zone.The concrete shape of each sub-pixel can be set according to preparation process
It sets.For example, the practical light-emitting zone can be determined by the shape of at least one electrode, luminescent layer, pixel defining layer.
For example, when this kind of pixel arrangement structure is applied to oled display substrate, the first sub-pixel and the 4th sub-pixel are phase
When with color, it is also possible that the luminous layer pattern application mask plate of the first sub-pixel and the 4th sub-pixel in same pixel groups
Same opening be deposited to be formed.
For example, the first sub-pixel 111 and the 4th sub-pixel 114 can be the sub-pixel of human eye sensitive colors, it may be, for example, green
Sub-pixels, yellow sub-pixel, white sub-pixels etc..For example, compared to the second sub-pixel 112 and third sub-pixel 113, first
The area of sub-pixel 111 and the 4th sub-pixel 114 is relatively small, for example, the area of the first sub-pixel 111 is less than the second sub-pixel
112, and/or, the area of the first sub-pixel 111 is less than the area of third sub-pixel 113.Similar, the 4th sub-pixel 114 can join
According to the above-mentioned description for 111 area of the first sub-pixel.
According to the display base plate that the utility model at least embodiment provides, pixel arrangement structure therein can pass through adjusting
The spacing of visual position sensitive colors sub-pixel improves the distributing homogeneity of sensitive colors sub-pixel, to which the pixel can be improved
The visual resolution ratio of arrangement architecture is promoted and shows quality.
Second sub-pixel 112 and third sub-pixel 113 can be the sub-pixel of the insensitive color of human eye.For example, the second sub- picture
Plain one of 112 and third sub-pixel 113 are red sub-pixel, another is blue subpixels, but not limited to this.The utility model
Embodiment in, be red sub-pixel with the second sub-pixel 112, third sub-pixel 113 is to illustrate for blue subpixels.
It should be noted that when pixel arrangement structure uses RGB (RGB) pattern, above-mentioned human eye sensitivity's color is can green.
As shown in Figure 2 E, the first line segment LS1 can extend along first direction X, and second line segment LS2 can be with Y in a second direction
Extend.For example, first direction X is perpendicular to second direction Y.For example, in each pixel groups 01, the first sub-pixel 111 and the 4th son
Pixel 114 is arranged using first direction X as symmetry axis, so that dot structure arrangement is evenly.For example, the first sub-pixel
111 opposite second sub-pixels 112 and third sub-pixel 113 are evenly distributed, are consistent, so that dot structure arrangement is more equal
It is even.
As shown in Figure 2 E, the display base plate provided according to the utility model one or more embodiment, pixel row therein
In array structure, second line segment LS2 is perpendicular to the first line segment LS1.To may make pixel arrangement evenly.For example, second line segment
LS2 is located on the perpendicular bisector of the first line segment LS1, at this point, width of the sub-pixel of each color in a first direction on X can be homogeneous
Together, but not limited to this.To may make dot structure to be more evenly distributed, image display quality higher improves under relatively low PPI
Show granular sensation problem.
As shown in Figure 2 E, for the convenience of description, giving the dotted line frame of multiple squares, the length of each dotted line frame is 1/
2L, four dotted line frames can form the square that the length of side is L.It is a pixel groups 01 in dark rectangular dotted line frame in Fig. 2 E.It should
Pixel groups 01 can be the minimum repetitive unit of the pixel arrangement structure.For example, pixel arrangement structure can pass through minimum repetitive unit
Shift copy and obtain.For example, not forming dot structure including translatable repetition to be arranged in minimum repetitive unit
Subelement.
As shown in Figure 2 E, the first line segment SL1 is vertical with second line segment SL2, and orthogonal divides equally.First line segment SL1 hangs down
Directly divide second line segment SL2 equally.Second line segment SL2 also vertically divides the first line segment SL1 equally.For example, in pixel groups 01, the first sub-pixel
111, the maximum region that the line at the center of the second sub-pixel 112, the 4th sub-pixel 114 and third sub-pixel 113 surrounds is in water chestnut
Shape, the first line segment SL1 and second line segment SL2 are respectively the diagonal line of the diamond shape.
As shown in Figure 2 E, in pixel groups 01, the center C4 of the center C1 and the 4th sub-pixel 114 of the first sub-pixel 111
The distance between can be greater than or equal to 1/2L, for example, the range of the distance can be from 1/2L to L.For example, 111 He of the first sub-pixel
