Abstract
An in-cell touch display device includes an in-cell touch panel, a backlight module driving circuit, a backlight module, a gate driving circuit, a touch processing circuit and a control circuit. The in-cell touch panel includes a plurality of gate lines and a plurality of touch sensing units. The control circuit is used for defining a plurality of gate line driving periods separated from each other in the time and at least one touch sensing period in a frame period. The touch sensing period is between two adjacent gate line driving periods. During the gate line driving periods, the control circuit controls the gate driving circuit to drive the gate lines sequentially and outputs a signal to the backlight module driving circuit to turn on the backlight module. During each touch sensing period, the control circuit controls the touch processing circuit to output a driving signal to the touch sensing units and outputs a signal to the backlight module driving circuit to turn off the backlight module.
