Abstract: A timing control circuit is provided to control a data voltage outputted to a pixel array of a display panel during a frame period to perform a polarity reversal every N scan lines, where N is a positive integer. The timing control circuit includes a receiver and an adjustment circuit. The receiver is configured to sequentially receive first display data and second display data for one data line of the display panel. The adjustment circuit is coupled to the receiver to adjust at least one of gray information of the second display data and charging time of the second display data according to a voltage polarity of the first display data and a voltage polarity of the second display data. A corresponding operation method of the timing control circuit is also provided.
