Abstract
A method for driving a plasma display panel capable of obtaining a good display quality. In a pixel data writing step in a sub-field that is weighted small, discharge cells in the plasma display panel are scanned in a unit of plurality of display lines and are set to one of a light emitting state and a non-light emitting state depending upon the pixel data.
Claims3
A method for driving a plasma display panel having discharge cells each corresponding to one pixel formed at each of intersecting points between a plurality of row electrodes corresponding to display lines and a plurality of column electrodes intersecting said row electrodes, in response to a video signal, at each of successively appearing sub-fields forming each of the fields of said video signal, which comprises:
- in each of said sub-fields, executing
- a pixel data writing step for setting said discharge cell to one of a light emitting state and a non-light emitting state in accordance with pixel data corresponding to the video signal;
- and
- a light emission sustaining step for causing only said discharge cell in said light emitting state to emit light by only a number of times assigned in relation to the weighting of each of said sub-fields, wherein
- in the pixel data writing step in a sub-field of a small weighting, one of said light emitting state and said non-light emitting state is selected every a plurality of said display lines which are simultaneously scanned, in the pixel data writing step in other sub-fields, one of said light emitting state and said non-light emitting state is selected at a display line.
