P‐95: Distortion of Sustain Waveform Relative to Displayed Area and Its Compensation for Stable Address Discharge in AC‐Plasma Display Panel

Abstract

The sustain waveforms are distorted relative to the displayed area. The distorted sustain waveform, especially the last X sustain waveform causes the address time to be delayed. Accordingly, to produce a stable address discharge irrespective of the displayed area, the sustain waveform, especially the last X sustain waveform prior to the selective reset waveform, is compensated by making its rising slope faster in proportion to the displayed area by means of controlling the timing sequence of the energy recovery circuit (ERC) circuit. As a result, the compensated sustain waveform enables the address delayed time to be saturated irrespective of the displayed area.
