Abstract
A driving device that drives a display device using a subfield driving method eliminates the need to use an expensive 1-frame delay memory. A compensated sustain pulse data generator enables displaying the same frame information on the display panel even when the 1-frame delay memory is eliminated. The drive data is generated so that the data that is delayed one frame and is included in the data output from the subfield processing unit and the data that is delayed one frame and is included in the data output from the compensated sustain pulse data generator are mutually cancelling.
