Patent ID: 7489288

Claim:
A drive control apparatus for a display panel formed by arranging a plurality of pixels having a plurality of cells emitting lights of different colors comprising: an obtaining device which obtains an image signal effecting a display on the display panel, and a drive device which generates a drive signal for driving the display panel based on the obtained image signal, a drive control device for detecting at least one of a cumulative light emitting number and a cumulative light emitting time with respect to each of the cells and also for judging whether or not the cumulative light emitting number or the cumulative light emitting time reaches a predetermined number or a predetermined time with respect to each of the cells, wherein the drive device generates the drive signal performing a reverse of a light emission mode which includes at least one of a reverse between a light emission state and a light stopping state for each of the cells and a reverse of gradation in the light emission state of each of the cells with respect to each of the cells when it is judged by the drive control device that the cumulative light emitting number reaches the predetermined number, the cumulative light emitting time reaches the predetermined time, or both the predetermined number and the predetermined time respectively reaches the predetermined number and the predetermined time.
