Abstract
A scan electrode driving circuit applies a rising ramp waveform voltage to scan electrodes (SCNto SCNn) to generate a first setup discharge in a first period within a setup period, applies a dropping ramp waveform voltage to the scan electrodes (SCNto SCNn) to generate a second setup discharge in a second period following the first period within the setup period, and applies a positive rectangular waveform voltage (Va) and a negative rectangular waveform voltage (Va) to the scan electrodes (SCNto SCNn) in a third period following the second period within the setup period. A data electrode driving circuit applies a positive rectangular waveform voltage (Vd) to data electrodes (Dto Dm) in a period after application of the positive rectangular waveform voltage (Vs) to the scan electrodes (SCN to SCNn) and before application of the negative rectangular waveform voltage (Va) to the scan electrodes (SCNto SCNn) in the third period.
