Transcapacitive sensor having gate lines used for both display updating and capacitive sensing
Capacitive sensing is performed in an input device having an input sensor and associated display device using gate lines of the display device. A transmitter signal having a negative pulse is used to safely transmit a transcapacitive transmitter signal while not opening any of the access transistors...
