1. An electronic device comprising:
a display configured to display a screen;
a display driver IC (DDI) configured to supply a data voltage for displaying the screen to the display; and
at least one processor, comprising processing circuitry, configured to transmit image data for setting the data voltage to the DDI,
wherein the DDI is configured to:
generate a synchronization signal for controlling a time point at which the data voltage is supplied to the display; and
deliver the synchronization signal to the at least one processor, and wherein the at least one processor is configured, individually or collectively, to:
select a time point, at which the image data starts to be transmitted, within a waiting period of the synchronization signal in a frame period set depending on an operating frequency of the electronic device;
assign a threshold time within the waiting period; and
send a command to the DDI to change the operating frequency based on whether the time point at which the image data starts to be transmitted is before or after the threshold time.
