Abstract
An image processing device includes a current limiter and a brightness controller. The current limiter calculates compensating data based on an on-pixel ratio of an image signal and calculates a compensation brightness data of the image signal based on the compensating data. The compensating data decreases the driving current of the image signal. The brightness controller selects one of a plurality of gamma sets and one of a plurality of dimming values based on the compensation brightness data.
