- Step 201 The first sub-pixel in the first row of sub-pixels loads a first data signal, and the second sub-pixel in the first row of sub-pixels loads a second data signal, where the first row The third sub-pixel in the sub-pixel loads a third data signal, and the fourth sub-pixel in the first row of sub-pixels loads a fourth data signal.
- Step 202 The second sub-pixel of the second row of sub-pixels loads a second data signal, and the third sub-pixel of the second row of sub-pixels loads a third data signal, where the second row The fourth sub-pixel in the sub-pixel loads a fourth data signal, and the first sub-pixel in the second row of sub-pixels loads the first data signal.
- Step 203 The fourth sub-pixel of the third row of sub-pixels loads a fourth data signal, and the first sub-pixel of the third row of sub-pixels loads a first data signal, where the third row The second sub-pixel in the sub-pixel loads a second data signal, and the third sub-pixel in the third row of sub-pixels loads a third data signal.
- Step 204 The third sub-pixel of the fourth row of sub-pixels loads a third data signal, and the fourth sub-pixel of the fourth row of sub-pixels loads a fourth data signal, where the fourth row The first sub-pixel in the sub-pixel loads a first data signal, and the second sub-pixel in the fourth row of sub-pixels loads a second data signal.
- the above steps 201 to 204 are repeatedly performed to complete the driving process for the entire display substrate.
- different ways of dividing the pixel unit correspond to different driving methods of the display substrate.
- four sub-pixels or two sub-pixels of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel form one pixel unit, the first data signal
- the number, the second data signal, the third data signal, and the fourth data signal are determined according to corresponding pixel units as their loading targets.
- a plurality of pixel groups repeatedly arranged are formed on the substrate, and each pixel group includes four first sub-pixels, second sub-pixels, and third sub-pixels.
- a pixel and a fourth sub-pixel, the sub-pixels in each pixel group are arranged in a 4 ⁇ 4 matrix, and each row of sub-pixels in each pixel group includes a first sub-pixel, a second sub-pixel, and a third sub-pixel.
- a fourth sub-pixel wherein the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel of the different row sub-pixels in each pixel group are sequentially arranged in a different order, and the sub-pixels of the same color are avoided.
- the pixels are located in the same column, so that the sub-pixels are evenly distributed, thereby avoiding serious white streaks in the grayscale image of the display device, thereby improving the display quality of the display screen.
