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.

Abstract: A display driving integrated circuit (DDIC) driving a display device and including; a host interface configured to receive image data from a host device, an interface monitor configured to generate a mode signal indicating a still image mode or a video mode by detecting whether the image data from the host device is transferred through the host interface, a processing circuit configured to generate processed data by processing the image data, a conversion circuit configured to perform data conversion on the processed data to generate display data driving a display panel, and a path controller configured to store the processed data in a frame buffer and transfer the processed data stored in the frame buffer to the conversion circuit in the still image mode, and further configured to transfer the processed data to the conversion circuit without storing the processed data in the frame buffer in the video mode.
