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

    The present invention provides an active X-ray sensing circuit and the sensing method thereof, it is applied in X-ray panel. The X-ray sensing circuit comprises two row of pixel circuit, and the two row of pixel circuit shares one scan line, and each data line connects with two switches. It is compensated the threshold voltage when it switches to the current source. It operates reading when it switches to amplifier. By applying specific scan line signal, the last-row pixel circuit is compensated and the next-row pixel row is read at the same time, so that the sensing circuit array can compensate and sense in one scan to avoid the effect of the leakage current.
