## Abstract

A pixel array is provided. The pixel array includes a plurality of pixel units. Each pixel unit correspondingly includes a plurality of sub-pixels having a plurality of color types, and the sub-pixels having the color types include at least one blue sub-pixel. In the pixel array, a proportion of the at least one blue sub-pixel is larger than a proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of other color types of the color types.

## Claims

### Claim 1

A pixel array, comprising: a plurality of pixel units, wherein each pixel unit correspondingly comprises a plurality of sub-pixels having a plurality of color types, and the sub-pixels having the color types comprise at least one blue sub-pixel; and
wherein in the pixel array, a proportion of the at least one blue sub-pixel is larger than a proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of other color types of the color types.

### Claim 2 (depends on 1)

The pixel array of claim 1, wherein the pixel units comprise at least one first pixel unit, and in each first pixel unit of the at least one first pixel unit, a proportion of the at least one blue sub-pixel is larger than a proportion correspondingly of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types.

### Claim 3 (depends on 2)

The pixel array of claim 2, wherein the pixel units further comprise at least one second pixel unit, and in each second pixel unit of the at least one second pixel unit, a proportion correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same.

### Claim 4 (depends on 2)

The pixel array of claim 2, wherein the at least one first pixel unit in the pixel array is evenly distributed.

### Claim 5 (depends on 2)

The pixel array of claim 2, wherein in each first pixel unit of the at least one first pixel unit, an area of a single pixel of at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same, and a number of a plurality of the blue sub-pixels is larger than a number correspondingly of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types.

### Claim 6 (depends on 2)

The pixel array of claim 2, wherein in each first pixel unit of the at least one first pixel unit, a number correspondingly of at least one sub-pixel of the sub-pixels correspondingly having each color type of the color types is same, and an area of a single pixel of the at least one blue sub-pixel is larger than an area correspondingly of a single pixel of the at least one sub-pixel of the sub-pixels correspondingly having each color type of the other color types of the color types.
