Abstract
A method for driving an AC type surface-discharge display device having cells arranged in a matrix. Each cell has at least three electrodes including a pair of main electrodes and on every line of the matrix and an address electrode on every column of the matrix. The method includes conducting an address preparation period including applying a first charge adjusting voltage, monotonously rising or falling, to a gap between the main electrodes. The method also includes applying a charge adjusting voltage, monotonously rising or falling, to a gap between a scan electrode and the address electrode.
