Abstract

A display device including a plurality of sub-pixel arrays is provided. Each of sub-pixel arrays includes a plurality of first sub-pixels, at least one second sub-pixel and at least one third sub-pixel. The first sub-pixels have a first color and form a plurality of vertexes of a virtual quadrilateral. There is not any other first sub-pixels having the first color located in the virtual quadrilateral. The second sub-pixel has a second color different from the first color and is located in the virtual quadrilateral. The third sub-pixel has a third color different from the first color and the second color and is located in the virtual quadrilateral.

Claims (23)

1. A driving device, capable for driving a display panel comprising a plurality of sub-pixel arrays, wherein each of the sub-pixel arrays comprises: a plurality of first sub-pixels having a first color; a plurality of second sub-pixels having a second color different from the first color; a plurality of third sub-pixels having a third color different from the first color and the second color; and a plurality of fourth sub-pixels having a fourth color different from the first color, the second color, and the third color, wherein the display panel is divided into a plurality of pixel units each containing at least a part of one of the sub-pixel arrays or one or more of the sub-pixel arrays, wherein the driving device comprises:

a source driving circuit, having one or more output terminals, wherein each output terminal is configured to output a respective drive voltage for driving sub-pixels belonging to at least one corresponding pixel unit of pixel units among the pixel units of the display panel,

wherein four of the first sub-pixels adjacent to each other form a first polygon, four of the second sub-pixels adjacent to each other form a second polygon, and an area of the first polygon is at least twice as large as an area of the second polygon, wherein the first sub-pixels, the second sub-pixels, the third sub-pixels, and the fourth sub-pixels are arranged to form a sub-pixel array of four columns and four rows, wherein a first column and a third column of the sub-pixel array respectively comprise two second sub-pixels and two fourth sub-pixels, and a second column and a fourth column of the sub-pixel array respectively comprise one first sub-pixel and three third sub-pixels.

2. The driving device of claim 1 , wherein the drive voltage has a plurality of periods, and each of the periods consists of image data for driving at least one sub-pixel located in one pixel unit of the at least one corresponding pixel unit of pixel units.

3. The driving device of claim 1 , wherein the source driving circuit further comprises:

a source image data receiving unit configured to receive source image data indicating an image, for rendering on the display panel; and

a sub-pixel rendering unit configured to compute luminance values for each sub-pixel of the display panel according to the source image data.

4. The driving device of claim 1 , wherein the display panel includes four colors in total.

5. A display device, comprising:

a display panel, comprising:

a plurality of sub-pixel arrays, wherein each of the sub-pixel arrays comprises:

a plurality of first sub-pixels having a first color;

a plurality of second sub-pixels having a second color different from the first color;

a plurality of third sub-pixels having a third color different from the first color and the second color; and

a plurality of fourth sub-pixels having a fourth color different from the first color, the second color, and the third color, wherein the display panel is divided into a plurality of pixel units each containing at least a part of one of the sub-pixel arrays or one or more of the sub-pixel arrays; and

a driving device, configured to drive the pixel units on the display panel,

wherein four of the first sub-pixels adjacent to each other form a first polygon, four of the second sub-pixels adjacent to each other form a second polygon, and an area of the first polygon is at least twice as large as an area of the second polygon, wherein the first sub-pixels, the second sub-pixels, the third sub-pixels, and the fourth sub-pixels are arranged to form a sub-pixel array of four columns and four rows, wherein a first column and a third column of the sub-pixel array respectively comprise two second sub-pixels and two fourth sub-pixels, and a second column and a fourth column of the sub-pixel array respectively comprise one first sub-pixel and three third sub-pixels.

6. The display device of claim 5 , wherein the driving device comprises a source driving circuit, having one or more output terminals, wherein each output terminal is configured to output a respective drive voltage for driving sub-pixels belonging to at least one corresponding pixel unit of pixel units among the pixel units of the display panel.

7. The display device of claim 6 , wherein the drive voltage has a plurality of periods, and each of the periods consists of image data for driving at least one sub-pixel located in one pixel unit of the at least one corresponding pixel unit of pixel units.

8. The display device of claim 6 , wherein the source driving circuit further comprises:

a source image data receiving unit configured to receive source image data indicating an image, for rendering on the display panel; and

a sub-pixel rendering unit configured to compute luminance values for each sub-pixel of the display panel according to the source image data.

9. The display device of claim 5 , wherein the display panel includes four colors in total.
