Abstract
The invention provides a driving method and a driving system for a display panel. The driving method comprises: partitioning the display panel into N display sub-areas, each of which is used for displaying the 1/N sub-picture of the whole frame of picture to be displayed and correspondingly controlled by one timing controller, wherein N≧2 and N is an integer, and the data signal of the whole frame of picture to be displayed is allocated to each of the timing controllers. According to the driving method and the driving system, by allocating the data signal of the whole frame of picture to be displayed to each of timing controllers, the backlight brightness provided by the different backlight sub-areas is the same, and then a joint or boundary phenomenon occurring among the different backlight sub-areas is avoided.
