the third subpixel in the second pixel has the same y-ordinate as the inverted third subpixel in the inverted second pixel;
the inverted first subpixel in the second pixel has the same y-ordinate as the first subpixel in the inverted second pixel;
the second subpixel in the third pixel has the same y-ordinate as the inverted second subpixel in the inverted third pixel; and
the inverted third subpixel in the third pixel has the same y-ordinate as the third subpixel in the inverted third pixel.

2. The pixel structure according to claim 1 , wherein each of the first subpixel, the second subpixel and the third subpixel takes a midpoint of a perpendicular line from its vertex to its base as its coordinate point.

3. The pixel structure according to claim 1 , further comprising:
a plurality of sampling regions,
wherein a center of each of the sampling regions coincides with the coordinate point of the first subpixel, or the second subpixel, or the third subpixel.

4. The pixel structure according to claim 3 , wherein the sampling region has a rectangle shape, a width of the rectangle is equal to a height of the first subpixel, and a length of the rectangle is equal to 1.5 times a length of a base of the first subpixel.

5. The pixel structure according to claim 1 , wherein the isosceles triangle is an equilateral triangle.

6. The pixel structure according to claim 1 , further comprising:
a drive unit configured to determine, upon receiving a white point display command, coordinates of the white point to be displayed, and to:
drive the first subpixel, the second subpixel and third subpixel with the determined coordinates as vertices; or
drive the inverted first subpixel, the inverted second subpixel and the inverted third subpixel with the determined coordinates as vertices.

7. The pixel structure according to claim 6 , wherein upon receiving a monochrome vertical line display command, the drive unit drives target color subpixels and/or inverted target color subpixels with a target y-ordinate.

8. The pixel structure according to claim 6 , wherein upon receiving a slash display command, the drive unit determines that coordinates of two starting subpixels of the slash to be displayed are (R m , A n ), (R m , A n+1 ) and coordinates of two end subpixels of the slash are (R m+k , A n+k ), (R m+k , A n+k+1 ), and drives subpixels with one or more colors and coordinates (R m+x , A n+x ), (R m+x , A n+x+1 ), where x is an integer greater than or equal to 0 and less than or equal to k, and m, n and k are positive integers.

9. The pixel structure according to claim 6 , wherein, upon receiving a display command, the drive unit determines an area to be displayed and subpixels to be displayed, allocates a luminance of a % to the subpixels to be displayed in the area to be displayed, and allocates a luminance of 0.5a % to subpixels having the same color as the subpixels to be displayed in an area adjacent to the area to be displayed, where a is a positive number.

10. The pixel structure according to claim 1 , wherein the first subpixel, the second subpixel and the third subpixel each include organic light emitting material.
