An OLED display driver integrated circuit and a display driving method are provided. The OLED display driver integrated circuit includes a timing control circuit. The timing control circuit is configured to receive an external vertical synchronization signal. The timing control circuit generates an internal vertical synchronization signal, and generates a first switching signal and a second switching signal according to the internal vertical synchronization signal. The timing control circuit determines whether to adjust a time point of a next pulse of the internal vertical synchronization signal according to a time point of the latest received pulse of the external vertical synchronization signal. The first switching signal and the second switching signal are output to an OLED display panel and utilized for controlling an emission control circuit disposed in the OLED display panel which is utilized for controlling an illuminating period of pixel units of the OLED display panel.

OLED display driver integrated circuit and display driving method

The disclosure is directed to a timing controller having a mechanism for frame synchronization, a display panel having the timing controller thereof, and a display system having the timing controller thereof. According to an aspect of the disclosure, the disclosure provides an integrated circuit which includes a timing controller to transmit a first TE signal to an application processor and receive a first image frame from the application processor after the application processor receives the first TE signal, and a control circuit to generate a first sync signal when the timing controller receives the first image frame, wherein when the application processor receives a second TE signal and the application processor is not ready to transmit a second image frame to the timing controller, the control circuit delays a first waiting period to generate a second sync signal.
