Liquid crystal display device to reduce afterimage

A method for driving display, applied to a display panel, wherein the display panel comprises a plurality of pixel units arranged in an array along a row direction and a column direction;

• the plurality of pixel units comprise a plurality of sub-pixel groups arranged in the row direction;
• each of the plurality of sub-pixel groups comprises a first sub-pixel and a second sub-pixel;
• and the first sub-pixel and the second sub-pixel are provided with a same color and arranged in a column direction;
• and the method for driving display comprises:
• determining a first target grayscale value and a second target grayscale value in a grayscale matrix of an image to be displayed, wherein the first target grayscale value and the second target grayscale value correspond to the first sub-pixel and the second sub-pixel of one of the plurality of sub-pixel groups respectively;
• determining a first actual grayscale value and a second actual grayscale value based on the first target grayscale value and the second target grayscale value, wherein the first actual grayscale value is greater than the first target grayscale value and the second target grayscale value, the second actual grayscale value is less than the first target grayscale value and the second target grayscale value, and the sum of a luminance value corresponding to the first actual grayscale value and a luminance value corresponding to the second actual grayscale value is equal to the sum of a luminance value corresponding to the first target grayscale value and a luminance value corresponding to the second target grayscale value;
• driving a corresponding first sub-pixel based on the first actual grayscale value and driving a corresponding second sub-pixel based on the second actual grayscale value in an nth display phase;
• and
• driving a corresponding second sub-pixel based on the first actual grayscale value, and driving a corresponding first sub-pixel based on the second actual grayscale value in an (n+1) th display phase;
• and
• wherein n is a positive integer.
