Embodiment 1
[0063] See figure 2 , figure 2 It is a flow chart of a pixel matrix driving method provided by an embodiment of the present invention. The pixel matrix driving method is suitable for current displays with pixel arrays, such as LCD displays, LED displays, OLED displays and the like.
[0064] Further, the pixel matrix includes a plurality of sub-pixels arranged in a matrix, and the polarity of the voltage applied along the data lines is exchanged every four sub-pixels, and any column of data lines controls the voltage input of a sub-pixel on both sides thereof, Along the direction of the data line, the voltage applied to the sub-pixel is to exchange the polarity every two sub-pixels, and along the direction of the scanning line, the voltage applied to the sub-pixel is to exchange the polarity every two sub-pixels; specifically, for the sub-pixel The polarity of the pixel is 2N inversion along the direction of the scan line and the direction of the data line, and the polarity...

[0085] You can also refer to the following examples, see Image 6 , Image 6 Another schematic diagram of pixel matrix grayscale loading provided by the embodiment of the present invention. The applying the first driving voltage or the second driving voltage to the pixel matrix along the data line direction includes:
[0086] Alternately applying the first driving voltage and the second driving voltage to adjacent sub-pixels along the direction of the data line, and the gray levels on adjacent sub-pixels on both sides of the data line are the same;
[0087] Along the scanning line direction, the first driving voltage and the second driving voltage are alternately applied to every two adjacent sub-pixels.
[0088] The gray levels of the adjacent sub-pixels on both sides of the data line are the same, which means that when the adjacent sub-pixel on the left side of the data line is H, the adjacent sub-pixel on the right side of the data line is H, and vice versa.

Embodiment 3
[0098] See Figure 8 , Figure 8 It is a flow chart of another pixel matrix driving method provided by an embodiment of the present invention. The pixel matrix includes a plurality of sub-pixels arranged in a matrix, the voltage applied to the sub-pixels is reversed every two sub-pixels along the direction of the data line, and the voltage applied to the sub-pixels is reversed along the direction of the scanning line Direction The polarity of each sub-pixel is reversed once;
[0099] Specifically, the method includes:
[0100] Step 1. Receive image data, and obtain original pixel data according to the image data;
[0101] Step 2, obtaining the original data driving signal of each pixel position according to the original pixel data;
[0102] Step 3, obtaining a first driving voltage and a second driving voltage according to the original data driving signal;
[0103] Step 4. In one frame, apply the first driving voltage or the second driving voltage to the pixel matrix alon...
