Abstract: Methods of driving source lines and/or circuits/systems for driving source lines are provided. Source lines of a display device are driven by comparing first data for driving a first buffer associated with a first source line of the display device and second data for driving a second buffer associated with a second source line of the display device and selectively disabling the second buffer and driving the second source line of the display device with the first buffer based on the comparison of the first and second data.

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.
