Abstract
The object of the invention is to provide a method for driving a plasma display panel that provides an improved expression of levels of halftone as well as an improved display quality. In N sub-fields constituting a display period of one field, when a pixel data writing step for setting discharge cells to either one of non-light-emitting cells or light-emitting cells in response to pixel data and a light-emission sustaining step for allowing only the aforementioned light-emitting cells to emit light only during a light-emission period corresponding to weights assigned to the sub-fields respectively are executed, the light-emission period in the light-emission sustaining step of the respective sub-fields is changed field by field or frame by frame. According to another aspect, the invention allows for carrying out selectively a first drive pattern or a second drive pattern. The first drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, first and second light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the light-emission sustaining step during one field (one frame). The second drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, third and fourth light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the aforementioned light-emission sustaining step.
