Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
What is claimed is: 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, each of the second and third sub-pixels being an integral structure, the second and third sub-pixels being common to four adjacent ones of the pixel units, 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, wherein each of the four pixel units comprises one of the four third sub-pixels, one of the four first sub-pixels and the one second sub-pixel shared in the four pixel units, each of the four first sub-pixels located between a corresponding one of the four third sub-pixels and the one second sub-pixel shared in the four pixel units, wherein each first sub-pixel is disposed on a line segment connecting centers of the third sub-pixel and the second sub-pixel positioned in a center of the quadrilateral, and wherein the first sub-pixel is a rectangle, each of the second and third sub-pixels is a square, two opposite short sides of each first sub-pixel are respectively substantially aligned with corresponding sides of its adjacent second and third sub-pixels. 2. The pixel structure of claim 1 , wherein short sides of each first sub-pixel are parallel to the line segment connecting centers of its adjacent second and third sub-pixels. 3. The pixel structure of claim 1 , wherein the first, second and third sub-pixels in one pixel unit are symmetric to corresponding ones in an adjacent pixel unit. 4. The pixel structure of claim 1 , wherein short sides of each first sub-pixel are perpendicular to the line segment connecting centers of its adjacent second and third sub-pixels. 5. The pixel structure of claim 1 , wherein the first sub-pixel has an area smaller than both an area of the second sub-pixel and an area of the third sub-pixel. 6. 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, each of the second and third sub-pixels being an integral structure, the second and third sub-pixels being common to four adjacent ones of the pixel units, 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, wherein each of the four pixel units comprises one of the four third sub-pixels, one of the four first sub-pixels and the one second sub-pixel shared in the four pixel units, each of the four first sub-pixels located between a corresponding one of the four third sub-pixels and the one second sub-pixel shared in the four pixel units, wherein each first sub-pixel is disposed on a line segment connecting centers of the third sub-pixel and the second sub-pixel positioned in a center of the quadrilateral, and wherein the first sub-pixel is a rectangle, each of the second and third sub-pixels is a square, two opposite short sides of each first sub-pixel are respectively substantially aligned with corresponding sides of its adjacent second and third sub-pixels.
