Embodiment Construction
[0041] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0042] The present invention firstly provides a fingerprint identification device. Since the sensing electrodes will block the thin film transistors and other parts of the circuit, it is difficult to simultaneously display the sensing electrodes and the thin film transistors in one picture. Therefore, the combined figure 1 , figure 2 The structure of the fingerprint identification device of the embodiment of the present invention is described, which includes:
[0043] A fingerprint identification module, a plurality of gate lines 101 and a plurality of signal lines 102;
[0044] Gate lines 101 and signal lines 102 are intersected to define a plurality of sensing regions 103, and each sensing region 103 is provided with a thin film transistor 104 and a ...
