TOUCH SENSING DISPLAY DEVICE WITH IN-CELL TOUCH PANEL

摘要

A touch sensing display device includes a touch panel and a signal processing circuit. The touch panel includes a plurality of pixel units, and the pixel units constitute a plurality of touch display units each comprising a touch sensing element. The touch sensing element is electrically coupled to a corresponding scanning line and electrically coupled to the signal processing circuit via a touch sensing line. A common voltage signal with a first polarity and an inversed second polarity is provided to the pixel unit. When the scanning line electrically coupled to the touch sensing element is provided with a scanning signal and the common voltage signal with the first polarity, a touch sensing signal generated by the touch sensing element is outputted to the signal processing circuit to enable the signal process circuit to generate a touch position indication signal.
