Study on High-Luminance Sustain Pulses Using Consecutive Second Emission in AC-PDP

In this paper, four different sustaining pulses are examined and their electrical and emissive characteristics are compared with those of the conventional pulse. For a comparative study, an infrared emission, luminance, and discharge current during the sustaining period are measured. A distinguishable second emission is observed after the ignition of sustaining discharge and during infrared measurements with the photometer and an intensified charge-coupled device. This is the main reason for enhancing the luminance during the sustaining period. One of the proposed pulses shows a stronger second emission than the other pulses. Its luminance is 25% and its efficiency is 47.3% higher than those of the conventional pulse.
