PLASMA DISPLAY AND DRIVING METHOD THEREOF

摘要

A plasma display device and a driving method thereof are provided to maintain color coordinates of a white color by compensating variation of brightness increasing rates due to the number of sustain discharges. A plasma display device includes plural column and row electrodes, and plural discharge cells, which are defined by the plural column and row electrodes. A frame is divided into plural subfields having respective brightness weighted values. A screen load rate of plural image data corresponding to the discharge cells is calculated(S710). Total numbers of sustain discharge corresponding to the frame according to the screen load rate are determined(S720). Weighted values of the subfields according to the total numbers of sustain discharges are determined(S750). The image data are converted to respective plural subfield data based on the weighted values(S760). A driving signal is applied to the column and row electrodes according to the respective plural subfield data.
