Abstract:
1. A method for driving an AC type surface-discharge display device having a plurality of cells arranged in a matrix, each cell having at least three electrodes including a pair of a first main electrode and a second main electrode disposed on every line of the matrix and an address electrode disposed on every column of the matrix, the method comprising: providing an address preparation period comprising: wherein the charge producing pulse has a positive polarity and is applied to the second main electrode used as a scan electrode, and said charge adjusting pulse has a waveform monotonously falling from a first predetermined potential to a second predetermined potential and a negative polarity and is applied to the second main electrode used as a scan electrode; and providing an address period sequentially applying a negative scan pulse, whose potential is lower than the second predetermined potential of the charge adjusting pulse, to the second main electrode, thereby to scan each of the lines of the matrix.
