ACTIVE CAPACITIVE PEN, AND TOUCH DETECTION AND FEEDBACK DRIVING METHODS THEREFOR

Disclosed are an active capacitive pen and touch detection and feedback driving methods therefor, the active capacitive pen comprising a conductive penpoint, a signal processing module and a capacitor, wherein the conductive penpoint is used for detecting a touch screen driving signal transmitted by a touch screen and transmitting a feedback driving signal output by the signal processing module; the signal processing module is used for processing the touch screen driving signal received by the conductive penpoint and generating a synchronous feedback driving signal; and the capacitor is provided between the conductive penpoint and the signal processing module, the capacitor is used for coupling the touch screen driving signal acquired by the conductive penpoint to an input end of the signal processing module during detection, and the capacitor is used for isolating the feedback driving signal when the touch screen is driven by a feedback. By means of the present invention, the purpose of accurately positionin
