Abstract:
A scan electrode driving circuit applies a rising ramp waveform voltage to scan electrodes (SCN1 to 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 (SCN1 to SCNn) to generate a second setup discharge in a second period following the first period within the setup period, and applies a first positive rectangular waveform voltage (Vs), a negative rectangular waveform voltage (Va), a second positive rectangular waveform voltage (Vs) and a dropping ramp waveform voltage to the scan electrodes (SCN1 to 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 (D1 to Dm) in a period after application of the first positive rectangular waveform voltage (Vs) to the scan electrodes (SCN1 to SCNn) and before application of the negative rectangular waveform voltage (Va) to the scan electrodes (SCN1 to SCNn) in the third period.
