The 3-dimensional analysis for the discharge of plasma display panel according to the voltage supplied to addresselectrode during sustain period

초록

To improve the luminance and luminous efficiency of AC PDP, the effects of auxiliary voltage pulse applied to the address electrode during a sustain period is investigated. Through this experiment, we confirmed the improvement of luminance and delay time. Also, we performed the temporal behavior measurement for the light emitted from AC PDP at various auxiliary voltages applied to the address electrode using the scanned point detecting system, In the case of using an auxiliary voltagepulse the light emission starts at the inner edge of the cathode, then spread to the outside of the cathode, and the lager discharge volume can be obtained compared with the normal sustain discharge. Especially, when the auxiliary voltage is the half of the sustain voltages and address pulse width is the 2㎲, the maximum luminance can be obtained.
