Abstract
A timing controller includes a frame memory capable of storing previous frame data, a comparator structured to output a selection control signal in response to comparison of the previous frame data supplied from the frame memory with current frame data, an overdriver unit structured to output a compensation data signal in response to comparison of the previous frame data and the current frame data, a saturation voltage data supplying unit structured to generate a saturation voltage data signal in response to comparison of the previous frame data and the current frame data, and an outputting unit capable of selectively outputting either the compensation data signal or the saturation voltage data signal in response to the selection control signal.
