1. An electronic device for display control, the electronic device comprising:
an application processor, configured to output an image frame according to a tearing effect (TE) signal;
a display control circuit, coupled to the application processor, configured to output the TE signal to the application processor and receive the image frame from the application processor, wherein the display control circuit comprises:
a data processing circuit, configured to generate a notification signal when the data processing circuit is ready to receive the image frame from the application processor; and
a timing controller, configured to receive the notification signal from the data processing circuit, and generate the TE signal having a first frequency during a period from a first time point when the notification signal is received to a second time point when the application processor starts transmitting the image frame to the data processing circuit, wherein the first frequency is greater than a reference frequency based on an output frame rate of the display control circuit.
