Abstract
By providing a signal transmitting module and a light-controlled module in a touch circuit, and when a light irradiating the light-controlled module changes caused by a touch region of a panel being touched in a scanning cycle, the light-controlled module controls the signal transmitting module to be in a first state in a next scanning cycle, otherwise controls the signal transmitting module to be in a second state in the next scanning cycle, in the first state, the signal transmitting module can transmit a signal transmitted by the first gate line to a signal line as a touch sensing signal, in the second state, the signal transmitting module is in an off-state, so that a signal transmitting line between the first gate line and the signal line is disconnected.
