Abstract: An electronic device includes a display panel that outputs content through a plurality of pixels, a display driver integrated circuit configured to transmit a driving signal for driving the display panel, and a processor configured to transmit image data and/or a control signal to the display driver integrated circuit. In the case where the display driver integrated circuit receives first image data transmitted together with a command of a first command group from the processor, the display driver integrated circuit is configured to store the first image data in a first memory area. In the case where the display driver integrated circuit receives second image data transmitted together with a command of a second command group from the processor, the display driver integrated circuit is configured to store the second image data in a second memory area different from the first memory area.
