Abstract
In this paper, we report the experimental findings for improving the luminance and luminance efficacy in an AC plasma display panel using a new sustain waveform. The original waveform consists of bipolar sustain pulses of equal amplitudes and widths on both the sustain and scan electrodes. The proposed waveform modifies the pulse width and amplitude of the conventional bipolar voltage pulses. On reducing the pulse width of one of the applied sustains pulse; we observe the increase in luminance by 17% and luminance efficacy by 36% which is independent of the pulse polarity. The application of negative wider pulse (2.1 μs) of high amplitude (180 V) and positive shorter pulse (0.5 μs) of low amplitude (30 V) yields additive enhancement of the luminance by 26% and luminance efficacy by 19%. This new sustain waveform can be used to develop new generation high efficacy plasma displays.
