Abstract: A TFT touch display device includes a plurality of mutually vertical control lines and sensor lines and a plurality of TFTs. Each TFT is disposed at an intersection of one of the plurality of control line and one of the plurality of sensor line. The TFT is connected to a corresponding control line, a corresponding sensor line, and a power source. When there is an object approaching to the TFT, the TFT is turned on and a back-channel current is generated. A control unit is connected to the plurality of control lines to respectively provide a control signal to the plurality of control lines. A current sensing unit is connected to the plurality of sensor lines to respectively sense a current generated by the TFTs.
