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...

Embodiments of the present invention provide a fingerprint identification driving circuit, an array substrate, a display device, and a fingerprint identification method, which relate to the field of display technology, and can avoid the problem that a first scanning line is provided with a corner in a non-display area, resulting in a larger wiring space. The fingerprint recognition driving circuit includes a row driving sub-circuit for inputting scanning signals to n rows of first scanning lines; the n rows of first scanning lines are divided into m signal line groups and the signal line group includes s first scanning lines. The fingerprint recognition drive circuit includes m fingerprint row drive units, the fingerprint row drive units are distributed on the extension line direction of the first scanning line, each fingerprint row drive unit is connected with a signal line group, and the fingerprint row drive unit is also connected with the first The clock signal terminal is connected to the fingerprint start signal terminal, and the fingerprint row driving unit is used to input the signal of the first clock signal terminal to the first scanning line in the signal line group row by row under the control of the fingerprint start signal terminal. The embodiment of the present invention is used for fingerprint recognition.
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...
