Abstract: A display device includes a display panel, a display driver integrated circuit and a driving control circuit. The display panel includes a plurality of pixels connected to a plurality of driving lines and a plurality of source lines. The display driver integrated circuit includes a driving control signal generator. The driving control signal generator generates a driving control signal based on display device information and pixel values corresponding to at least a portion of the plurality of rows among a plurality of previous pixel values of a previous frame and a plurality of present pixel values of a present frame. The driving control circuit selectively connects the display driver integrated circuit with each of the plurality of driving lines based on the driving control signal such that first driving signals provided to first driving lines among the plurality of driving lines are blocked.
