Abstract
In one embodiment of the present invention, an overdrive (OD) method includes: acquiring a display grayscale value of a current frame within a display grayscale range; obtaining a target grayscale value of the current frame within a target grayscale range according to the display grayscale value of the current frame, where a minimum target grayscale value is larger than a minimum display grayscale value, and/or a maximum target grayscale value is smaller than a maximum display grayscale value, and each display grayscale value within the display grayscale range correspond one by one to one target grayscale value within the target grayscale range; and obtaining a system grayscale value of the current frame according to the target grayscale value of the current frame and a display grayscale value or a system grayscale value of a previous frame, and outputting a corresponding gamma voltage according to the system grayscale value.
