PLASMA DISPLAY DEVICE AND PLASMA DISPLAY PANEL DRIVING METHOD

摘要

Image display quality is improved by achieving uniform display luminance. To this end, a sustained pulse generation circuit selects any of multiple drive patterns based on a total cell lighting ratio and a partial lighting ratio and generates a sustained pulse. An image signal processing circuit (41) has a loading correction unit (70) which is equipped with a lighted cell number computation unit (60) which computes the number of discharge cells to be lighted per each pair of display electrodes and per each sub-field, a load value computation unit (61) which computes the load value for each of the discharge cells based on the computation results of the lighted cell number computation unit (60), a correction gain computation unit (62) which computes a correction gain for each of the discharge cells based on the computation results of the load value computation unit (61), the selected drive pattern, and the position of the discharge cell, and a correction unit (69) which corrects an input image signal based on the output from the correction gain computation unit (62).
