1. An electronic device comprising:
a peripheral device;
a display;
a display driver integrated circuit (DDIC) configured to drive the display and to output a tearing effect (TE) signal having a designated frequency; and
a processor configured to:
control the peripheral device, the display, and the DDIC, and
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.
