Abstract
A method and an apparatus for improving the gray-scale linearity of a plasma display. At least two types of gray-scale allocations are mixed for forming the original gray scale, or different gray scales are mixed to derive the original gray scale, so as to obtain the required brightness. Therefore, by using multiple combinations to adjust the original gray scale, the required brightness is obtained, and the gray scale linearity for all the gray scales is improved.
