Abstract

A driving system of touch display panel includes a panel having an active area and a plurality of touch electrodes, and a gate driving circuit connected with a plurality of gate lines. There is at least one gate line not covered by the touch electrodes among the gate lines disposed in a range constituted by vertically adjacent touch electrodes. The gate line not covered by the touch electrode, at least one gate line previous thereto, and at least one gate line next thereto are selected as the gate lines that influence coupling. When driving the gate lines that influence coupling, the gate driving circuit enables a time difference between an active time of each at least one gate line among the gate lines that influence coupling and an active time of a gate line previous thereto to be greater than a predetermined interval.
