Claim Text:
1. A pixel driving circuit for driving a pixel array, wherein each pixel in the pixel array comprises four sub-pixels with different colors, and wherein the pixel driving circuit comprises at least one first sub-pixel driving chip and at least one second sub-pixel driving chip, wherein the at least one first sub-pixel driving chip each is connected to a part of sub-pixels corresponding thereto in corresponding pixels to drive them, and the at least one second sub-pixel driving chip each is connected to the other part of sub-pixels corresponding thereto in the corresponding pixels to drive them; wherein in each pixel in the pixel array, the sub-pixels are arranged side by side in one row in the pixel array; the at least one first sub-pixel driving chip each is connected to two sub-pixels in each corresponding pixel, and the at least one second sub-pixel driving chip each is connected to the other two sub-pixels in each corresponding pixel; and wherein the pixel driving circuit further comprises a timing controller, the at least one first sub-pixel driving chip and the at least one second sub-pixel driving chip are connected to the timing controller respectively, the timing controller enables the first sub-pixel driving chip and the second sub-pixel driving chip for the same corresponding pixel to apply driving voltages to the sub-pixels in the corresponding pixel simultaneously.
