Abstract
A display driver integrated circuit (IC) (DDI) includes a graphic memory that receives and stores line data including a plurality of pixel data blocks, an indicator generating circuit that compares the pixel data blocks of the line data received by the graphic memory with each other and generates an indicator signal corresponding to results of the comparison, and a read controller that performs a read operation with respect to the whole or a part of the line data from the graphic memory, based on a read command for the line data and the indicator signal.
