Claim 11:
12. A method for driving a display panel, the display panel comprising a plurality of compression units arranged in an array, the method comprising:
obtaining a compression parameter and a decompression method;
determining a pixel to be tested in the compression unit according to the compression parameter;
obtaining a compensation parameter corresponding to the subject driving voltage value of the pixel to be tested;
performing a fitting operation on the compensation parameter to obtain a fitted compensation parameter;
determining compressed de-Mura data corresponding to the compression unit according to the fitted compensation parameter;
obtaining a gamma curve and a luminance value of a target pixel;
determining the standard driving voltage value of the target pixel when the subject display content is being displayed according to the gamma value and the luminance value of the target pixel;
obtaining a target compression unit corresponding to the target pixel;
determining a corresponding target compensation curve parameter from compressed de-Mura data corresponding to the target compression unit according to the standard driving voltage value, wherein the compressed de-Mura data comprise each subject driving voltage value and a corresponding compensation curve parameter of the target compression unit;
determining an effective driving voltage value of the target pixel when the subject content is being displayed according to a position information where the target pixel is in the target compression unit and the target compensation curve parameter; and
driving the display panel according to the effective driving voltage of the target pixel of the display panel.
