TOUCH CIRCUIT AND METHOD FOR DRIVING THE SAME, ARRAY SUBSTRATE, TOUCH DISPLAY DEVICE

摘要

Provided are a touch circuit and a method for driving the same, an array substrate, a touch display device. 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.

主权项

1. A touch circuit, comprising:
a signal transmitting module, a first end of which is connected to a first gate line, a second end of which is connected to a signal line, the signal transmitting module having a first state in which the signal transmitting module transmits a signal transmitted by the first gate line to the signal line as a touch sensing signal, and a second state in which the signal transmitting module is in an off-state so as to disconnect a signal transmitting line between the first gate line and the signal line; a light-controlled module, arranged corresponding to a touch region, and configured to control the signal transmitting module to be in the first state in a next scanning cycle when the touch region is touched in a scanning cycle and the light irradiating the light-controlled module changes, and control the signal transmitting module to be in the second state in the next scanning cycle when the touch region is not touched in the scanning cycle and the light irradiating the light-controlled module does not change, wherein a first end of the light-controlled module is connected to a second gate line, a second end of the light-controlled module is connected to the signal transmitting module.
