ABSTRACT:
A method of driving a gas discharge tube is provided. Each field of images is divided into three periods for luminescence-rest, luminescence-preparing, and luminescence steps. During the luminescence-rest step, two voltages whose amplitudes are the same and constant are applied to two sustaining electrodes composing each pair, so that the sustaining electrodes rest the discharge. During the luminescence-preparing step, two voltage pulses whose phases are the same are applied to the two sustaining electrodes composing each pair and a voltage to cause a preparatory discharge is applied to an auxiliary electrode. And during the luminescence step, two voltage pulses whose phases are mutually shifted are applied to the two sustaining electrodes composing each pair, so that the sustaining electrodes cause discharges for the luminescence.
