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 ...

Abstract

The invention provides a fingerprint identification member, a touch control panel, an input device and a fingerprint identification method. The fingerprint identification member comprises a fingerprint identification module, a grid electrode wire and a signal wire; the grid electrode wire and the signal wire define a plurality of induction areas by crossing arrangement; each induction area is provided with a film transistor and an induction electrode connected to the film transistor; the grid electrode of the film transistor is connected to the grid wire, the source electrode is connected to the signal wire, and the drain electrode is connected to the induction electrode; the signal wire comprises an emission signal wire and a reception signal wire; the induction electrode comprises an emission electrode and a reception electrode; an electric field from the emission electrode to the reception electrode is generated between the adjacent emission electrode and the reception electrode; the fingerprint identification module is connected to the reception signal wire; and the fingerprint texture can be determined through detecting the intensity of the electric field where the finger surface is positioned. The fingerprint identification member, the control panel, the input device and the fingerprint identification method have good adaptability in electronic goods.

Description

technical field [0001] The invention relates to electronics and display technology, in particular to a fingerprint identification device, a touch panel, an input device and a fingerprint identification method. Background technique [0002] With the development of the market, fingerprint identification technology has become one of the important functions of electronic products.
