Abstract

The invention provides a display panel. The display panel includes a plurality of pixels. Each pixel includes a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel, and the first color sub-pixel consists of a light region and a dark region.

Claims

1. A display panel, comprising:

a plurality of pixels, wherein each pixel comprises a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a fourth color sub-pixel, and the first color sub-pixel consists of a bright region and a dark region.

2. The display panel as claimed in claim 1, wherein the bright region and the dark region of the first color sub-pixel are accomplished by a charge-sharing operation

3. The display panel as claimed in claim 1, wherein of the bright region and the dark region of the first color sub-pixel are accomplished by a two transistor operation.

4. The display panel as claimed in claim 1, wherein the first color sub-pixel is a white sub-pixel.

5. The display panel as claimed in claim 1, wherein the second color sub-pixel consists of a bright region and a dark region.

6. The display panel as claimed in claim 5, wherein the second color sub-pixel is a blue sub-pixel.

7. The display panel as claimed in claim 5, wherein a low color shift (LCS) display mode of the second color sub-pixel is controlled to be turned on or turned off according to a desired color grayscale value.

8. The display panel as claimed in claim 1, wherein the fourth color sub-pixel consists of one region, and the fourth color sub-pixel is not divided into a bright region and a dark region.

9. The display panel as claimed in claim 8, wherein the fourth color sub-pixel is not a white sub-pixel.

10. The display panel as claimed in claim 3, wherein the bright region of the first color sub-pixel has a charging polarity opposite to a charging polarity of the dark region of the first color sub-pixel.

11. The display panel as claimed in claim 3, wherein the first color sub-pixel has one gate signal line and two data signal lines.

12. The display panel as claimed in claim 11, wherein the third color sub-pixel is adjacent to the bright region of the first color sub-pixel along the gate signal line direction, and the third color sub-pixel has a charging polarity opposite to a charging polarity of the bright region of the first color sub-pixel.

13. The display panel as claimed in claim 11, wherein the third color sub-pixel is adjacent to the dark region of the first color sub-pixel along the gate signal line direction, and the third color sub-pixel has a charging polarity opposite to a charging polarity of the dark region of the first color sub-pixel.

14. The display panel as claimed in claim 3, wherein the first color sub-pixel has two gate signal lines and one data signal line.

15. The display panel as claimed in claim 14, wherein the third color sub-pixel is adjacent to the bright region of the first color sub-pixel along the data signal line direction, and the third color sub-pixel has a charging polarity opposite to a charging polarity of the bright region of the first color sub-pixel.

16. The display panel as claimed in claim 14, wherein the third color sub-pixel is adjacent to the dark region of the first color sub-pixel along the data signal line direction, and the third color sub-pixel has a charging polarity opposite to a charging polarity of the dark region of the first color sub-pixel.

17. The display panel as claimed in claim 1, wherein the bright region of the first color sub-pixel has an area equal to an area of the dark region of the first color sub-pixel.

18. The display panel as claimed in claim 1,

wherein the bright region of the first color sub-pixel has an area not equal to an area of the dark region of the first color sub-pixel.

19. The display panel as claimed in claim 1, wherein the areas of the first color sub-pixel, the second color sub-pixel, the third color sub-pixel, and the fourth color sub-pixel are equal to each other.

20. The display panel as claimed in claim 1, wherein the first color sub-pixel, the second color sub-pixel, the third color sub-pixel, and the fourth color sub-pixel are arranged to form a square arrangement.
