Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] An embodiment of the present invention provides a fingerprint identification driving circuit, such as figure 2 As shown, it includes a row driving sub-circuit 20 for inputting scan signals to n rows of first scan lines (G_f1, G_f2 . . . G_fn).

[0039] On this basis, n rows of first scanning lines ( G_f1 , G_f2 . . . G_fn) can be divided into m signal line groups 10 , and each signal line group 10 includes s first scanning lines G_f. Wherein, s×m=n, s...

Abstract

An embodiment of the invention provides a fingerprint identification driving circuit, an array substrate, a display device and a fingerprint identification method, wherein the fingerprint identification driving circuit, the array substrate, the display device and the fingerprint identification method relate to the field of displaying technology and can prevent problems of relatively large wiring space caused by corners of first scanning wires in a non-displaying area. The fingerprint identification driving circuit comprises a line driving subcircuit which is used for inputting a scanning signal to n lines of first scanning wires. The n lines of first scanning wires are divided into m signal wire sets, wherein each signal wire set comprises s first scanning wires. The fingerprint identification driving circuit comprises m fingerprint line driving units. The fingerprint line driving units are distributed in an extending line direction of the first scanning wires. Each fingerprint line driving unit is connected with a signal wire set. The fingerprint line driving unit is connected with a first clock signal end and a fingerprint starting signal end. The fingerprint line driving unit is used for inputting the signal of the first clock signal end to the first scanning wire in the signal wire set through controlling by the fingerprint starting signal end. The fingerprint identification driving circuit, the array substrate, the display device and the fingerprint identification method are used for fingerprint identification.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fingerprint identification drive circuit, an array substrate, a display device and a fingerprint identification method. Background technique [0002] Human fingerprints are unique and invariant, so fingerprint recognition technology has the characteristics of good security, high reliability, and simple and convenient use, making fingerprint recognition technology widely used in various fields of personal information security protection, especially in the field of display technology , such as mobile phones, laptops, tablet computers, digital cameras, etc. [0003] On this basis, for the convenience and diversity of fingerprint identification, the components for real fingerprint identification can be arranged in the display area of ​​the display panel. Such as figure 1 As shown, a plurality of fingerprint identification elements 100 are arranged in a matrix form in the display...
