Patent ID: 7042424

Claim:
A method for driving a plasma display panel wherein discharge cells are formed corresponding to pixels at respective intersections between a plurality of row electrodes disposed in an array for respective scan lines and a plurality of column electrodes disposed in an array crossing said row electrodes, having a light-emission drive sequence comprising the steps of: executing pixel data writing step for setting, in each of N (N being a natural number) divided display periods constituting a unit display period, said discharge cells to either one of non-light-emitting cells or light-emitting cells in response to N-bit display drive pixel data obtained by applying the multi-level grey-scale processing to input video signal in each of said divided display periods, and executing a light emission sustaining step for allowing only said light-emitting cells to emit light by the number of times corresponding to each of weights assigned to said divided display periods respectively, wherein said light-emission drive sequence comprises a first drive pattern to be carried out by alternating, at intervals of said respective unit display period, first and second light-emission drive sequences which have ratios of the number of times of light-emission different from each other in said light-emission sustaining period of said respective N divided display periods, and a second drive pattern to be carried out by alternating, at intervals of said respective unit display period, third and fourth light-emission drive sequences which have ratios of the number of times of light-emission different from each other in said light-emission sustaining period of said respective N divided display periods, and said first drive pattern and said second drive pattern are selectively executed in accordance with the type of said input video signal.
