摘要:
In order to realize a display having good contrast and stable addressing by using a gas discharge display device having a screen of a three-electrode surface discharge structure having a characteristics that a counter discharge start voltage is higher than a surface discharge start voltage, prior to starting of initialization of an electrified state as canceling of setting of addressing that was performed last, positive charge is formed between opposed electrodes so that a discharge can be generated easily in the addressing after the initialization, and the initialization is performed so that the formed positive charge does not vanish.

A plasma display having a discharge cell the emission efficiency of which is improved by generating first and second discharges with one sustaining pulse (Psu). The first discharge is generated by increasing the voltage up to a maximal value Vpu through LC resonance by a recovery coil L and a panel capacitor Cp. The second discharge is generated by connecting the panel capacitor Cp with a power supply when the voltage drops from the maximal value Vpu down to Vpb and thereby increasing the voltage up to Vsus.
摘要:
In a driving method for a plasma display panel, in the initializing period in at least one of a plurality of subfields, selective initializing operation is performed that selectively causes initializing discharge only in a discharge cell having undergone address discharge in an immediately preceding address period. The selective initializing operation includes the step of applying first voltage to the sustain electrode and applying an up-ramp waveform voltage to the scan electrode, the step of applying a down-ramp waveform voltage to the scan electrode and then applying a positive rectangular voltage to it, and the step of applying second voltage higher than the first voltage to the sustain electrode and applying a down-ramp waveform voltage to the scan electrode.
