Claim:
1. A display panel driving method, wherein the display panel comprises a first display area and a second display area, and a first time sequence controller and a second time sequence controller corresponding to the first display area and the second display area respectively; the driving method comprises the first time sequence controller obtaining a first frame synchronization signal according to an obtained display signal of the first display area, the first frame synchronization signal comprising a starting time of a first line of scanning signals of the first display area, the second time sequence controller obtaining a second frame synchronization signal according to an obtained display signal of the second display area, the second frame synchronization signal comprising a starting time of a first line of scanning signals of the second display area, the first time sequence controller and the second time sequence controller obtaining a time delay between the starting time of the first line of the scanning signals of the first display area and the starting time of the first line of the scanning signals of the second display area, and the first time sequence controller and the second time sequence controller adjusting the starting times of the first lines of the scanning signals of the respective first and second display areas according to the time delay so as to make the starting times of the first lines of the scanning signals of the first and second display areas are the same; the first time sequence controller obtaining a third frame synchronization signal according to the display signal of the first display area, the third frame synchronization signal comprising a starting time of the last line of the scanning signals of the first display area; the first time sequence controller adjusting the starting time of each line of the scanning signals of the first display area by bringing forward starting locations of the gate driving signals on the different lines by (m−1)*second delay time/(n−1) according to the second delay time between the starting time of the first line of the scanning signals and the starting time of the last line of the scanning signals of the first display area so that the starting times of all lines of the adjusted scanning signals of the first display area are the same, wherein m represents a number of line at which the gate driving signal is located, and n represents a vertical resolution of the display signals.
