Abstract
A touch circuit includes a touch IC and a logic sub-circuit. The touch IC includes a touch signal port. The logic sub-circuit is connected to the touch signal port, and is configured to transmit a touch enabling signal to the touch signal port. The logic sub-circuit includes an AND gate. The AND gate includes a first input terminal, a second input terminal and an output terminal electrically connected to the touch signal port. The AND gate is configured to output the touch enabling signal through the output terminal electrically connected to the touch signal port in response to receiving one of a backlight turn-on signal and a screen turn-on signal through the first input terminal, and a touch generation signal through the second input terminal.
