Abstract
A method for improving image display quality, including: dividing a total gray scale range of a gamma voltage curve of a display apparatus to obtain gray scale ranges; obtaining data of gray scales of frame(s) of image to be displayed by the display apparatus, and calculating a ratio of data of gray scales in each gray scale range; adjusting a division value of a gamma voltage range corresponding to each gray scale range of the gamma voltage curve according to calculated ratios, so that a division value of a gamma voltage range corresponding to a gray scale range with a maximum ratio is less than a division value of a gamma voltage range corresponding to any remaining gray scale range; and outputting gamma voltages corresponding to the data of gray scales of the frame(s) of image to be displayed according to the adjusted gamma voltage curve.
