  • Patent number: 9607542
    Abstract: The embodiments of the present invention provide a display panel driving method, a driving device and a display device, which can improve the time delay of the gate driving signals of a partitioned controlled display panel and reduce the production cost. The display panel comprises at least two time sequence controllers and at least two display areas, each of the time controllers corresponding to one of the display areas respectively; the driving method comprises each of the time sequence controllers obtaining a synchronization signal according to an obtained display signal of the corresponding display area, the synchronization signal comprising a starting time of a first line of scanning signals of the corresponding display area, the time sequence controllers adjusting the starting times of the first lines of the scanning signals according to the synchronization signals of at least one display area so as to make the starting times of the first lines of the scanning signals of all display areas are the same.
