Abstract

A fingerprint identification module and a fingerprint identification method are provided. The fingerprint identification module comprises: a transparent cover plate, the transparent cover plate comprising a display area and an edge area surrounding the display area; a display screen body located on one side of the display area of the transparent cover plate; an optical sensor located on the surface of one side of the edge area of the transparent cover plate and surrounding the display area, with the optical sensor and the display screen body being located on the same side of the transparent cover plate; a plurality of light sources located on the surface of the side, back on to the edge area, of the optical sensor and distributed around the display area at intervals, the light sources being suitable for being electrically connected with the optical sensor. According to the fingerprint identification module, full-screen fingerprint identification can be realized, and the limitation on the display screen body is reduced.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification module and a fingerprint identification method. Background technique [0002] The current fingerprint identification schemes are mainly divided into three categories: capacitive, ultrasonic and optical. Regardless of the fingerprint recognition technology, based on the design difficulty and cost considerations, the current notebook computer equipment and design are fingerprint recognition in a small local area. For example, the capacitive fingerprint recognition sensor is based on the design of semiconductor silicon materials. Its disadvantage is that it cannot penetrate glass and display screens above 300um, and the cost is high, so it cannot realize fingerprint recognition in a large area; ultrasonic and optical sensors are both There are materials based on semiconductor silicon technology and materials based on TFT glass, and th...
