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.
