| Abstract |
The discharge characteristics for the reset period of sustain pulses of display discharge in address overlapped display driving methode is studied. It has been understood that the display discharge is strongly influenced of not only the wall charge but also the space charge from the experiment result. The first display discharge which comes out exactly after the rest periods strongly depends on the width of the reset period and as for the second display discharge, the dependancy of it is very low. Even if the first display discharge is a little insufficient, if the wall charge is accumulated enough, the second display discharge can be stably induced. However, considering the influence of the space charge, it is preferable within the width of 30[㎲] of the reset period. When the rest period is up to 30[㎲], the uniform voltage operation margin of the display discharge of about 12[V] was obtained. |
