Abstract:
A driving method for a plasma display panel wherein gradation is expressed by dividing one frame into a plurality of sub-fields, said driving method comprising the steps of:preparing frames in each of which number of priming discharge periods is set up in relation to an average picture level of images, the number of sub-fields in each of said frames being equal to one another; selecting a frame from said frames in accordance with an average picture level; conducting sustaining discharges in a first sub-field as a pair of adjacent first and second sub-fields; and conducting writing discharges in said second sub-field after said sustaining discharges in said first sub-field without conducting any erasure discharge between said sustaining discharges and said writing discharges when the number of priming discharge periods in a selected frame is less than the number of sub-fields in said selected frame, wherein the higher the average picture level, the higher the number of priming discharges is set up in said frame.
