A TFT module includes TFTs; gate bus lines; a plurality of source bus lines; unit electrodes connected with the source bus lines via the TFTs; a gate driver configured to supply a scan signal from a first end of the gate bus lines and a source driver configured to supply a data signal from a first end of the source bus lines, the gate driver and the source driver being provided in a second region lying around a first region in which the unit electrodes are provided; current sensing circuits provided in the second region; and feedback lines. Each of the feedback lines is connected with a corresponding current sensing circuit and with a second end of a corresponding source bus line or gate bus line, the second end being opposite to the first end.

TFT module, scanned antenna provided with TFT module, method for driving device provided with TFT module, and method for producing device provided with TFT module

A scanned antenna according to an embodiment includes a plurality of first antenna elements and a plurality of second antenna elements. The first antenna elements are driven by a gate driver connected to a plurality of first gate bus lines and a first source driver connected to a plurality of first source bus lines. The second antenna elements are driven by a gate driver connected to a plurality of second gate bus lines and a second source driver connected to a plurality of second source bus lines. The gate driver and the gate driver operate independently of each other, and the first source driver and the second source driver operate independently of each other.
