Driving circuit and driving method for touch device, touch device, and display device
The present disclosure provides a driving circuit and a driving method for a touch device, a touch device and a display device. The driving circuit includes an operational amplifier and a control circuit. A negative input terminal of the operational amplifier is connected with a touch-sensing electrode included in the touch device, and a positive input terminal of the operational amplifier is connected with the control circuit. The control circuit is to, at a touch stage, adjust a voltage at the positive input terminal of the operational amplifier to be within a first predetermined voltage range so as to control the touch-sensing electrode to implement a touch sensing operation, and at a display stage, adjust the voltage at the positive input terminal of the operational amplifier to be within a second predetermined voltage range so as to shield external static electricity.
