Classification: CPC G | IPC G

Claim 4:
5. An operating method of an electronic device comprising an application processor and a display control circuit, the operating method comprising:
generating, by a data processing circuit of the display control circuit, a notification signal when the data processing circuit is ready to receive an image frame from the application processor;
receiving, by a timing controller of the display control circuit, the notification signal from the data processing circuit;
generating, by the timing controller of the display control circuit, a TE signal having a first frequency during a period from a first time point to a second time point; and
transmitting, by the application processor, the image frame to the data processing circuit according to the TE signal,
wherein the notification signal is received by the timing controller at the first time point, the image frame is started transmitting to the data processing circuit at the second time point, and the first frequency of the TE signal is greater than a reference frequency based on an output frame rate of the display control circuit.
