Liquid crystal display having particular sub-pixels
View Patent ↗A four color liquid crystal display (LCD) including red, green, blue, and white sub-pixels are provided. The LCD also includes a plurality of gate lines for transmitting gate signals to the sub-pixels and a plurality of data lines for transmitting data signals to the sub-pixels. The white sub-pixel is smaller than the other sub-pixels, and each of the data lines passes between adjacent two sub-pixels and includes at least one curved portion. Furthermore, the lengths of the data lines are substantially uniform.
1. A liquid crystal display comprising:
a plurality of gate lines and a plurality of data lines intersecting each other; and
a plurality of pixels connected to the gate lines and the data lines, each pixel including red, green, blue, and white sub-pixels,
wherein the white sub-pixel is smaller than the red, green, and blue sub-pixels, each data line passes between two sub-pixels and has at least a curve portion, and the length of the data lines is substantially uniform.
2. The liquid crystal display of claim 1 , wherein the sub-pixels have substantially an equal length, the white sub-pixel has a width smaller than the widths of the red, blue, and green sub-pixels, the sub-pixels are affanged to form a plurality of rows, the sub-pixels in each row are affanged in turn, and sub-pixel affangements in adjacent rows are shifted by a predetermined s number of sub-pixels.
3. The liquid crystal display of claim 2 , wherein each row includes red, green, white, and blue sub-pixels sequentially arranged in a first direction, the red and white sub-pixels are adjacent in a second direction, and a straight line extending in the second direction and passing through a center of the red sub-pixel passes through a center of the white sub-pixel.
4. The liquid crystal display of claim 3 , wherein each pixel comprises a red sub-pixel, a white sub-pixel adjacent to the red sub-pixel in the second direction, and green and blue sub-pixels adjacent to the white sub-pixel in the first direction.
5. The liquid crystal display of claim 3 , wherein each pixel comprises a red sub-pixel, a green sub-pixel adjacent to the red sub-pixel in the first direction, and white and blue sub-pixels adjacent to the red and green sub-pixels in the second direction, respectively.
6. The liquid crystal display of claim 3 , wherein the sub-pixels are subjected to 1×1 line inversion.
7. The liquid crystal display of claim 3 , wherein the sub-pixels are subjected to 1×1 dot inversion.
8. The liquid crystal display of claim 2 , wherein sub-pixel arrangements in adjacent rows are shifted by two sub-pixels.
9. The liquid crystal display of claim 1 , wherein the liquid crystal display is subjected to sub-pixel rendering.
10. The liquid crystal display of claim 9 , wherein the sub-pixels are arranged to form a plurality of rows, the sub-pixels in each row are arranged in turn, and sub-pixel affangements in adjacent rows are shifted by a predetermined number of sub-pixels.
11. The liquid crystal display of claim 10 , wherein a logical pixel for the sub-pixel rendering comprises red and green sub-pixels adjacent to each other in a first row, and white and blue sub-pixels that belong to a second row adjacent to the first row and are adjacent to the red and green sub-pixels, respectively.
12. The liquid crystal display of claim 10 , wherein a logical pixel for the sub-pixel rendering comprises a red sub-pixel in a first row, a white sub-pixel that belongs to a second row adjacent to the first row and is disposed adjacent to the red sub-pixel, and green and blue sub-pixels that belong to the second row and are disposed adjacent to the white sub-pixel.
