METHOD FOR REVERSE-GAMMA COMPENSATION OF PLASMA DISPLAY PANEL

摘要

Disclosed is a method for reverse-gamma correction of a plasma display panel, which can improve image quality in a low gray scale region by calculating an output of gamma depending on an APL. The method includes selecting a plurality of APL points in an APL curve; calculating the number of sustain pulses for each subfield based on an APL point, calculating a luminance value at each of the APL points based on an SFM level; calculating an output luminance value at each of the APL points based on an input gray scale to which gamma characteristics are applied; and calculating an output of gamma at each of the APL points based on an input gray scale.
