Method for driving plasma display panel

Abstract

A method of driving a plasma display panel wherein a wide-band flicker can be minimized in a driving method of carrying out a selective writing and a selective erasing at the same time. In the method, the plasma display panel has first and second sustain electrodes and an address electrode and including at least one selective writing sub-fields for expressing a low gray level by turning on selected discharge cells and sustaining a discharge of the turned-on cells, and at least one selective erasing sub-fields for expressing a high gray level by sequentially turning off the cells turned on at the last selective writing sub-field of said selective writing sub-fields. Any one of said selective erasing sub-fields is divided into at least two sub-fields in such a manner to be arranged into low gray level sub-fields. Accordingly, the number of sub-fields in one frame is increased to reduce the vertical frame blank VFB and to enlarge a duty circle of light emission for the middle gray level expression, thereby eliminating a 50 Hz wide-band flicker.
