Problems solved by technology

This distance has far exceeded the effective distance between the user's finger surface and the fingerprint recognition sensor, resulting in the failure of the fingerprint recognition sensor and the inability to recognize the valleys and ridges of the user's fingerprint to form a fingerprint pattern. Therefore, there are two technical problems that need to be overcome in this field: 1. Reduce the distance between the finger surface and the fingerprint recognition sensor; 2. Increase the strength of the electromagnetic field of the fingerprint sensor so that its strength can penetrate the cover above 300 microns

Abstract

The invention provides a fingerprint identification device. The fingerprint identification device comprises a cover plate element, a base plate and a first thin plate and a second thin plate which are attached on the base plate, wherein a flexible circuit board is provided with at least one control element and at least one fingerprint sensor; the at least one fingerprint induction sensor is configured to sense fingerprints of fingers of a user; the at least one control element is configured to control the fingerprint sensor; the flexible circuit board extends between the base plate and the second thin plate through the side edge of the base plate to the second surface of the base plate; the fingerprint sensor is fixedly arranged between the second thin plate and the base plate so that the at least one fingerprint sensor is mounted at the position which is closer to the fingers of the user than the base plate. According to the fingerprint identification device, the base plate is provided with the first thin plate and the second thin plate so that a flat surface without an opening is formed, and the appearance and strength are complete and good.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification device, a touch screen and electronic equipment. Background technique [0002] With the development of science and technology, fingerprint recognition devices have been more and more widely used in various portable electronic devices. For example, there is a smart phone equipped with a fingerprint identification device, through which the user can realize functions such as unlocking the mobile phone, fingerprint identification payment, and the like. [0003] Existing electronic products, such as mobile phones, tablet computers and other electronic devices, need to punch holes in their touch cover plates in order to realize the fingerprint recognition function, and use LGA (Land Grid Array, grid array packaging) packaging technology in the electronic devices. The fingerprint sensor is attached to the hole of the cover plate, and then...
