Abstract
The present invention provides a time division driving method for touch display screen, comprising multiple driving periods. For any two adjacent driving periods, in a former driving period, the method comprises: S1, providing scanning signals to N scanning lines sequentially arranged; S2, stopping providing scanning signals, and providing touch driving signals to the touch display screen; in a latter driving period, the method comprises: S3, providing scanning signals to N scanning lines sequentially arranged; S4, stopping providing scanning signals, and providing touch driving signals to the touch display screen, wherein the first n scanning lines scanned in step S3 are the last n scanning lines scanned in step S1, both N and n are positive integers and N>n; and gray-level signals of the first n scanning lines scanned in step S3 are the same as those of the last n scanning lines scanned in step S1.
