Abstract
Display luminance is uniformized to enhance image display quality. A sustain pulse generating circuit generates sustain pulses by selecting any one of a plurality of driving patterns, according to an all-cell light-emitting rate and a partial light-emitting rate. A loading correction part of the image signal processing circuit includes: number of lit cells calculator for calculating the number of discharge cells to be lit in each display electrode pair, in each subfield; load value calculator for calculating a load value of each discharge cell, according to the calculation result in number of lit cells calculator; correction gain calculator for calculating a correction gain of each discharge cell, according the calculation result in load value calculator, the driving pattern selected, and the position of the discharge cell; and corrector for correcting an input image signal, according to the output from correction gain calculator.
