Abstract

An electronic device includes an application processor and a display control circuit. The display control circuit may output a (tearing effect) TE signal to the application processor and receive an image frame from the application processor. A data processing circuit of the display control circuit generates a notification signal when the data processing circuit is ready to receive the image frame from the application processor. The timing controller generates 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. The first frequency is greater than a reference frequency based on an output frame rate of the display control circuit.
