Abstract

A pixel structure and an organic light-emitting diode (OLED) display panel incorporating the pixel structure are disclosed. The pixel structure includes a plurality of pixel units ( 110 ) arranged in an array, each pixel unit comprising a first sub-pixel ( 111 ), a second sub-pixel ( 112 ) and a third sub-pixel ( 113 ). The second sub-pixel ( 112 ) and the third sub-pixel ( 113 ) are common to four adjacent pixel units ( 110 ). As a result, a higher aperture ratio of the sub-pixels, an increased design margin and reduced process difficulty can be obtained.

First claim

1 . A pixel structure, comprising a plurality of pixel units arranged in an array, each pixel unit comprising a first sub-pixel, a second sub-pixel and a third sub-pixel, the second and third sub-pixels being common to four adjacent ones of the pixel units.

2 . The pixel structure of claim 1 , wherein adjacent four third sub-pixels are arranged to define a quadrilateral encompassing one second sub-pixel and adjacent four first sub-pixels so that four pixel units are formed in which each of the four first sub-pixels is located between the second sub-pixel and a corresponding one of the four third sub-pixels.

3 . The pixel structure of claim 2 , wherein each first sub-pixel resides on a line segment connecting centers of its adjacent second and third sub-pixels.

4 . The pixel structure of claim 1 , wherein the first, second and third sub-pixels are all polygons.

5 . The pixel structure of claim 1 , wherein the first, second and third sub-pixels are quadrilaterals, hexagons, octagons or any combination thereof.

6 . The pixel structure of claim 5 , wherein the first sub-pixel is a rectangle, with each of the second and third sub-pixels being a square.

7 . The pixel structure of claim 6 , wherein short sides of each first sub-pixel are parallel to a line segment connecting centers of its adjacent second and third sub-pixels; or short sides of each first sub-pixel are perpendicular to a line segment connecting centers of its adjacent second and third sub-pixels.

8 . The pixel structure of claim 6 , wherein the first, second and third sub-pixels in one pixel unit are symmetric to corresponding ones in an adjacent pixel unit.

9 . The pixel structure of claim 1 , wherein the first sub-pixel has an area smaller than an area of the second and third sub-pixels.

10 . An OLED display panel, comprising a pixel structure, the pixel structure comprising a plurality of pixel units arranged in an array, each pixel unit comprising a first sub-pixel, a second sub-pixel and a third sub-pixel, the second and third sub-pixels being common to four adjacent ones of the pixel units.
