Abstract: A display driver integrated circuit is disclosed. The display driver integrated circuit includes panel signal supply circuitry configured to supply an image signal corresponding to image data to a panel, pixel power supply circuitry configured to supply pixel power to a pixel that receives the image signal, and a controller configured to control the pixel power supply circuitry to supply the pixel power based on an on-pixel ratio (OPR) value of the image data.

Abstract: An electronic device is provided. The electronic device may include a display driver module configured to, in response to receiving display data, divide the display data into a plurality of segments corresponding to a plurality of display regions, compare the display data in the plurality of segments to determine whether the display data in at least one segment is substantially same as the display data in another segment, and based on the comparison outcome, selectively amplify a first display signal generated from the display data in the at least one segment or a second display signal generated from the display data in the another segment.
