Abstract
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.
