    • 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.
    • TFT触摸显示装置包括多个相互垂直的控制线和传感器线以及多个TFT。 每个TFT设置在多个控制线之一和多个传感器线中的一个的交叉点处。 TFT连接到相应的控制线,相应的传感器线和电源。 当存在接近TFT的物体时,TFT导通,产生反向通道电流。 控制单元连接到多个控制线,以分别向多个控制线提供控制信号。 电流感测单元连接到多个传感器线以分别感测由TFT产生的电流。
