Abstract:
An interference-free fingerprint identification device includes a TFT substrate, a TFT layer having plural TFTs, a sensing electrode layer having plural fingerprint sensing electrodes, a gate line layer having plural gate lines, a data line layer having plural data lines, and a first shielding layer. Each fingerprint sensing electrode corresponds to a plurality of the TFTs, and is connected to sources or drains of at least two corresponding TFTs. At least two gate lines are electrically connected to gates of a plurality of the TFTs corresponding to a fingerprint sensing electrode. Each data line is electrically connected to a source or drain of a TFT in a plurality of the TFTs corresponding to a fingerprint sensing electrode. The first shielding layer is electrically connected to a source or drain of a TFT in a plurality of the TFTs corresponding to each fingerprint sensing electrode.
