Patent ID: 7133008

Claim:
A drive method for a display panel that selectively applies a plurality of drive pulses corresponding to a gradation of an image based on an input image signal, said method comprising: a calculation process of finding a multiplied product of a total number of sustain pulses applied in a field and an Average Picture Level value in said field, wherein, the total number of sustain pulses, which are determined according to a preset Automatic Brightness Limiter for said field, correspond to weighting given to respective sub-fields in said field for each cell of said display panel; accumulating a total number of said multiplied product in each said field; and a control process of controlling a specified amount of drive in said field for said display panel based on said accumulated total number of said multiplied product for each said field in order to compensate for change over time of said display panel, wherein said control process controls a timing at which said drive pulses are applied to said display panel based on an accumulated total number of light emissions in order to compensate for change over time of said display panel, wherein said control process controls timings of sustain pulses in order that a rise timing of a following sustain pulse IPy comes earlier and approaches a fall timing of a leading sustain pulse IPx, and said IPx and said IPy are applied to a same cell in said display panel.
