Abstract
The present disclosure provides a method for determining an overdrive mapping correlation in a display panel. The method includes the following steps. First, a repeating subpixel arrangement is determined. The subpixel arrangement includes at least three sets of subpixels in the display panel. An ideal luminance value of a pattern of the subpixel arrangement is then determined. The pattern includes at least a first set of subpixels displaying a zero pixel value, a second set of subpixels displaying a first nonzero pixel value, and a third set of subpixels displaying a second nonzero pixel value, the first, second and third sets of subpixels respectively arranged one after another. The first nonzero pixel value may be different from the second nonzero gray scale value. An actual luminance value of the pattern of the subpixel arrangement is then determined. An overdrive pixel value is further determined.
