Abstract

A pixel array includes a plurality of repeating units. Each repeating unit includes three first color sub-pixels, four second color sub-pixels, and three third color sub-pixels. The size of one of the first color sub-pixels is greater than the size of each of the other two first color sub-pixels. The sizes of the four second color sub-pixels are the same. The size of one of the third color sub-pixels is greater than the size of each of the other two third color sub-pixels.

First claim

What is claimed is:

1. A pixel array, comprising a plurality of repeating units, wherein each repeating unit comprises:
three first color sub-pixels, wherein a size of one of the first color sub-pixels is greater than a size of each of the other two first color sub-pixels;
four second color sub-pixels, wherein sizes of each of the four second color sub-pixels are the same;
three third color sub-pixels, wherein a size of one of the third color sub-pixels is greater than a size of each of the other two third color sub-pixels; and
two scan lines and five data lines, wherein the first color sub-pixels, the second color sub-pixels, and the third color sub-pixels are arranged in an array of 2×5.

2. The pixel array of claim 1 , wherein the size of the one of the first color sub-pixels is twice the size of each of the other two first color sub-pixels.

3. The pixel array of claim 1 , wherein the size of the one of the third color sub-pixels is twice the size of each of the other two third color sub-pixels.

4. The pixel array of claim 1 , wherein the size of each of the four second color sub-pixels is the same as the size of each of the other two first color sub-pixels, and the size of each of the four second color sub-pixels is the same as the size of each of the other two third color sub-pixels.

5. The pixel array of claim 1 , wherein each of the first color sub-pixels, the second color sub-pixels, and the third color sub-pixels comprises:
one of the two scan lines and one of the five data lines; and
a driving element electrically connected to the one of the two scan lines and the one of the five data lines.

6. The pixel array of claim 1 , wherein the first color sub-pixels are red sub-pixels, the second color sub-pixels are green sub-pixels, and the third color sub-pixels are blue sub-pixels.
