Abstract

Disclosed is a pixel unit structure and display device, which belongs to the technical field of displays, and alleviates the problem that in the prior arts, a LCS design will reduce the transparency of the liquid crystal display device. The pixel unit structure comprises three different colored sub-pixels, namely a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein at least one of the three sub-pixels is divided into a primary pixel region and a secondary pixel region, and the green sub-pixel has a one-piece structure.

Claims

1. A pixel unit structure, comprising three different colored sub-pixels, namely a red sub-pixel, a green sub-pixel, and a blue sub-pixel,

wherein at least one of the three sub-pixels is divided into a primary pixel region and a secondary pixel region, and the green sub-pixel has a one-piece structure, and

wherein the red sub-pixel is divided into a primary pixel region and a secondary pixel region.

2. The pixel unit structure according to claim 1, wherein the brightness of the primary pixel region is higher than that of the secondary pixel region.

3. The pixel unit structure according to claim 1, wherein the area of the primary pixel region is larger than that of the secondary pixel region.

4. The pixel unit structure according to claim 1, wherein the primary pixel region and the secondary pixel region each comprise four pixel domains.

5. The pixel unit structure according to claim 1, wherein the blue sub-pixel has a one-piece structure.

6. The pixel unit structure according to claim 1, wherein the blue sub-pixel is divided into a primary pixel region and a secondary pixel region.

7. A display device, comprising a plurality of pixel units, each of the pixel units including a pixel unit structure comprising three different colored sub-pixels, namely a red sub-pixel, a green sub-pixel, and a blue sub-pixel,

wherein at least one of the three sub-pixels is divided into a primary pixel region and a secondary pixel region, and the green sub-pixel has a one-piece structure, and

wherein the red sub-pixel is divided into a primary pixel region and a secondary pixel region.

8. The display device according to claim 7, wherein the brightness of the primary pixel region is higher than that of the secondary pixel region.

9. The display device according to claim 7, wherein the area of the primary pixel region is larger than that of the secondary pixel region.

10. The display device according to claim 7, wherein the primary pixel region and the secondary pixel region each comprise four pixel domains.

11. The display device according to claim 7, wherein the blue sub-pixel has a one-piece structure.

12. The display device according to claim 7, wherein the blue sub-pixel is divided into a primary pixel region and a secondary pixel region.

13. The display device according to claim 7, wherein the display device is a vertical alignment display device.
