Abstract

The pixel structure includes a plurality of pixel units each including a first sub-pixel with a first color, having a first adjoining edge of a first length and a second adjoining edge of a second length; a second sub-pixel with a second color, having a first adjoining edge of the first length and a second adjoining edge of a third length; and a third sub-pixel with a third color, having a first adjoining edge of the second length and a second adjoining edge of the third length. In each pixel unit, the first adjoining edge of the first sub-pixel is adjoined to the first adjoining edge of the second sub-pixel, the second adjoining edge of the first sub-pixel is adjoined to the first adjoining edge of the third sub-pixel, and the second adjoining edge of the second sub-pixel is adjoined to the second adjoining edge of the third sub-pixel.

First claim
