Improvement of plasma discharge characteristics in blue cells of AC plasma display panel using auxiliary pulse driving scheme

In order to improve the luminance in blue cells, which has been one of serious problems in a conventional plasma display panel, the application of an auxiliary short pulse to the address electrode in blue cell during a sustain-period is suggested. This driving scheme changes the discharge phenomena in a blue cell and affects the operating voltage margin, that is, the difference between firing voltage and sustain voltage, and undesired firing. In this study, an auxiliary short pulse driving scheme for improving the plasma discharge characteristic in blue cells is proposed and its effects on the operating voltage margin and undesired firing are also investigated.
