Abstract
A method for driving a display based on a perceptual quantizer includes establishing a relationship among an initial grayscale level, a desired grayscale level and a target grayscale value, confirming an actual target grayscale value to convert a pixel in the display from the initial grayscale level to the corresponding desired grayscale level based on the relationship, and using the actual target grayscale value to convert the pixel in the display from the initial grayscale level to the corresponding desired grayscale level. The target grayscale value is used to accelerate the conversion of the initial grayscale level to the corresponding desired grayscale level. The target grayscale value is established based on the initial grayscale level, the desired grayscale level and a visible area.
