Driving method and driving system for display panel

摘要

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.

1. A driving method for a display panel, comprising: partitioning the display panel into N display sub-areas, each of which is configured for displaying a 1/N subpicture of a whole frame of picture to be displayed and correspondingly controlled by one timing controller, wherein N>2 and N is an integer;
wherein a data signal of the whole frame of picture to be displayed is allocated to each of the timing controllers; wherein before allocating the data signal of the whole frame of picture to be displayed to each of the timing controllers, the driving method further comprises: calculating delay time of each of the timing controllers while receiving the data signal of the whole frame of picture to be displayed, and compensating for the delay time, so that the data signal of the whole frame of picture to be displayed is synchronously input to each of the timing controllers; and wherein a feedback signal is automatically transmitted by each of the timing controllers while receiving the data signal of the whole frame of picture to be displayed, and the delay time of one of the timing controllers while receiving the data signal of the whole frame of picture to be displayed relative to the other timing controllers while receiving the data signal of the whole frame picture to be displayed is calculated according to the feedback signal.
