Claim 6:
7. The method according to claim 1, wherein calculating the reference gamma voltages of two end points corresponding to the gray scale coordinates of two end points in the gray scale range with the maximum ratio, includes:
obtaining a luminance range that the display apparatus is capable of outputting;
calculating reference luminance of two end points corresponding to the gray scale coordinates of two end points in the gray scale range with the maximum ratio according to the luminance range, a number of gray scale coordinates in the gray scale range with the maximum ratio and a total number of gray scale coordinates in the total gray scale range; and
calculating voltages required for the reference luminance of two end points according to the reference luminance of two end points, and making the calculated two voltages serve as the reference gamma voltages of two end points corresponding to the gray scale coordinates of two end points in the gray scale range with the maximum ratio.
