Pixel structure, display substrate and display device
View Patent ↗A pixel structure, a display substrate and a display device are disclosed. The pixel structure includes a plurality of reduplicated units, wherein each of the reduplicated units includes: a red sub-pixel (A 1 ), a green sub-pixel (A 2 ), a blue sub-pixel (A 3 ) and a central sub-pixel (W) all in a shape of a triangle, wherein a color of the central sub-pixel (W) is different from that of any of the red sub-pixel (A 1 ), the green sub-pixel (A 2 ) and the blue sub-pixel (A 3 ), and the three sides of the central sub-pixel (W) respectively coincide with one side of the red sub-pixel (A 1 ), one side of the green sub-pixel (A 2 ) and one side of the blue sub-pixel (A 3 ). By designing the shape of the sub-pixel unit to be a triangle, it is possible to allow the red, green and blue sub-pixels (A 1 , A 2 , A 3 ) surrounding the three sides of the central sub-pixel (W) and to guarantee the central sub-pixel (W) to be adjacent to the other three sub-pixels (A 1 , A 2 , A 3 ), thus increasing the luminance while realizing homogeneous color mixing of different colors of sub-pixels, thereby improving the display quality.
1. A pixel structure, comprising a plurality of reduplicated units, wherein each of the reduplicated units comprises:
a red sub-pixel, a green sub-pixel, a blue sub-pixel and a central sub-pixel all in a shape of a triangle, wherein a color of the central sub-pixel is different from that of any of the red sub-pixel, the green sub-pixel and the blue sub-pixel, and three sides of the central sub-pixel respectively coincide with one side of the red sub-pixel, one side of the green sub-pixel and one side of the blue sub-pixel;
wherein the red sub-pixel, the green sub-pixel, the blue sub-pixel and the central sub-pixel are all in a shape of isosceles right triangle.
2. The pixel structure of claim 1 , wherein the color of the central sub-pixel is yellow or white.
3. The pixel structure of claim 1 , wherein each of the reduplicated units comprises a third pixel unit, the third pixel unit comprises a red sub-pixel, a green sub-pixel, a blue sub-pixel and a central sub-pixel.
4. The pixel structure of claim 3 , wherein each of the reduplicated units further comprises:
a fourth pixel unit, wherein the fourth pixel unit and the third pixel unit are central symmetric and together form a reduplicated unit having a shape of square.
5. The pixel structure of claim 4 , wherein a hypotenuse of the central sub-pixel coincides with a hypotenuse of the blue sub-pixel.
6. The pixel structure of claim 3 , wherein a hypotenuse of the central sub-pixel coincides with a hypotenuse of the blue sub-pixel.
7. The pixel structure of claim 1 , wherein a hypotenuse of the central sub-pixel coincides with a hypotenuse of the blue sub-pixel.
8. A display substrate, comprising a substrate and a pixel structure formed on the substrate, wherein the pixel structure is the pixel structure of claim 1 .
9. A display device, comprising the display substrate of claim 8 .
