Pixel structure and OLED display panel
View Patent ↗A pixel structure and an Organic Light-Emitting Diode (OLED) display panel. The pixel structure includes a number of pixel groups. Each of the pixel groups includes a first pixel and a second pixel adjacent in a first direction and disposed in a staggered manner in a second direction perpendicular to the first direction. Each of the first pixel and the second pixel includes sub-pixels of three different colors arranged along the second direction. A distance between two sub-pixels of a same color respectively of the first pixel and the second pixel in the first direction is equal to that in the second direction.
1. A pixel structure, comprising:
a plurality of pixel groups, each of the pixel groups including a first pixel and a second pixel adjacent in a first direction and disposed in a staggered manner in a second direction perpendicular to the first direction,
each of the first pixel and the second pixel including sub-pixels of three different colors arranged along the second direction, wherein a shape and an area of the sub-pixels in the pixel group are respectively the same, and in each of the first pixel and the second pixel, adjacent sub-pixels share one side which defines a borderline between the adjacent sub-pixels, and
wherein a distance between two sub-pixels of a same color respectively of the first pixel and the second pixel in the first direction is equal to that in the second direction.
2. The pixel structure according to claim 1 , wherein a central line of a first sub-pixel in the second pixel extending along the first direction overlaps with the borderline between a first sub-pixel and a second sub-pixel in the first pixel; or
a central line of a first sub-pixel in the first pixel extending along the first direction overlaps the borderline between a first sub-pixel and a second sub-pixel in the second pixel.
3. The pixel structure according to claim 1 , wherein the first pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel sequentially arranged along the second direction; and
the second pixel includes a third sub-pixel, a first sub-pixel, and a second sub-pixel sequentially arranged along the second direction.
4. The pixel structure according to claim 1 , wherein a length-to-width ratio of an aperture of each of the sub-pixels ranges from 1 to 1.5.
5. The pixel structure according to claim 1 , wherein in the second direction, distances between centers of adjacent two sub-pixels are same.
6. The pixel structure according to claim 1 , wherein a shape and an area of the sub-pixels of a same color in the first pixel is same to that in the second pixel, respectively.
7. The pixel structure according to claim 1 , wherein the sub-pixels include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.
8. The pixel structure according to claim 1 , wherein the first direction is a row direction and the second direction is a column direction; or
the first direction is a column direction and the second direction is a row direction.
9. An Organic Light-Emitting Diode (OLED) display panel comprising the pixel structure according to claim 1 .
10. The pixel structure according to claim 1 , wherein in each of the pixel groups, the first pixel and the second pixel are separated in the first direction by a spacing.
11. The pixel structure according to claim 1 , wherein in each of the pixel groups, the first pixel and the second pixel are staggered in the second direction by half a size of one sub-pixel in the second direction.
12. The pixel structure according to claim 1 , wherein the distance between two sub-pixels of the same color respectively of the first pixel and the second pixel in each of the first and second directions is 1.5 times a size of one sub-pixel in the second direction.
