Abstract
A method for driving an AC-type Plasma Display Panel (PDP), and more particularly, for improving the brightness and contrast of the panel by reducing the time of scanning while increasing the discharge time of cells. Accordingly, a video signal is designed to change, as needed, the sequential order of two bits, to insert appropriate erasing pulses into vertical electrodes according to the sequential order of the two bits, and to select the erasing time of each cell being connected to horizontal electrodes. Thus, combining any two or a plurality of subfields reduces the time of scanning while increasing the discharging time of the cells.
