METHOD FOR DRIVING SCANNING-SUSTAINING SEPARATING AC TYPE PLASMA DISPLAY PANEL, AND APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To attain formation of sufficient wall charges on a scanning electrode and a sustaining electrode even if a pulse width is shortened. SOLUTION: A driving mode of a scanning driver 34i and a sustaining driver 36i for a preliminary discharge period to a scanning electrode Si and a sustaining electrode Ci is made to be the same as conventional. The driving mode to the scanning electrode for a scanning period is also the same as conventional except the following items. At the time of finishing the scanning pulse applied to the scanning electrode, a potential in which a write wall charge forming pulse is superposed on a sustaining pulse is applied to the sustaining electrode Ci for 3 to 5μsec. At the time of ending this application, the scanning electrode Si and the sustaining electrode Ci are charged with wall charges larger than conventional. COPYRIGHT: (C)2005,JPO&NCIPI
