Abstract
An electronic device that quickly updates a screen when receiving an input from a peripheral device is provided. The electronic device includes a display driver integrated circuit (DDIC) configured to output a tearing effect (TE) signal having a designated frequency, and a processor configured to control the peripheral device, a display, and the DDIC and to transmit image data to the DDIC in response to the TE signal, wherein the DDIC is configured to output the TE signal at a first frequency, receive an interrupt signal from the peripheral device while the TE signal is output at the first frequency, output the TE signal at a second frequency in response to the interrupt signal, the second frequency being greater than the first frequency, receive image data updated by the processor based on the TE signal output at the second frequency, and drive the display to display the received image data.
