Abstract

The invention discloses an active matrix touch sensing circuit apparatus (300) used in a touch panel comprising a sensing unit (310), a resistance (308), and a thin film transistor (302). The resistance connects the sensing unit (310) and the first scan line. The control end (3022) of the thin film transistor (302) connects the sensing unit (310), the second scan line connects the input end (3024) of the thin film transistor (302), and the read out line connects the output end (3026) of the thin film transistor (302). When the sensing value of the body touch sensing unit (310) is changed, then the input wave form of the control end (3026) is changed. The output end (3026) generates an open current, and the read out line transmits the open current.
