ABSTRACT:
A method for driving a matrix type of plasma display panel displaying an image with a stable display operation in error-discharge free. The last pulse of the discharge-sustaining pulses in the sustained discharge period is adjusted to be shorter than that of the immediately previous pulse of the discharge-sustaining pulses and/or an address-pulse is applied to the column electrode in the simultaneous time of the applying of the discharge-sustaining pulses to generate the discharge between the paired row and column electrodes. The residual wall charges remaining the lightened pixel cell and the darkened pixel cell are uniformed at the end of sustained discharge period so that a stable addressing operation and precise emission displaying associated with the pixel data is achieved in the next addressing period.
