Claim 8:
9. The method according to claim 8, wherein adjusting the division value of the gamma voltage range corresponding to each gray scale range of the gamma voltage curve according to the calculated ratio so that the division value of the gamma voltage range corresponding to the gray scale range with the maximum ratio is less than the division value of the gamma voltage range corresponding to any remaining gray scale range, further includes:
calculating reference gamma voltages of two end points corresponding to gray scale coordinates of two end points in a continuous gray scale range; and
calculating a division value of a gamma voltage range corresponding to the continuous gray scale range according to a difference between the reference gamma voltages of two end points corresponding to the continuous gray scale range and a difference between the gray scale coordinates of two end points in the continuous gray scale range, wherein
the division value of the gamma voltage range corresponding to the gray scale range with the maximum ratio and the division value of the gamma voltage range corresponding to the gray scale range with the secondary maximum ratio are calculated, the continuous gray scale range is a continuous gray scale range composed of gray scale ranges except the gray scale range with the maximum ratio and the gray scale range with the secondary maximum ratio in the plurality of gray scale ranges.
