Fingerprint recognition device, touch screen and terminal equipment

Abstract

The present invention discloses a fingerprint recognition device, comprising a cover plate element and a fingerprint recognition module, wherein the cover plate element comprises a first part and a second part which are connected with each other, the first part is an integral mechanism, the second part comprises a substrate and a cover plate which are stacked; the fingerprint recognition module comprises at least one fingerprint sensor; the second part of the cover plate element is provided with at least one groove, the fingerprint recognition module is at least partly contained in the groove, so that the at least one fingerprint sensor can be arranged at the position closer, than the substrate, to a finger of a user; the second part of the cover plate element is provided with at least one layer of color layer, the color of the color layer at the position surrounding the fingerprint recognition module is different from the color of the color layer at other positions. In this way, the user can see the fingerprint recognition area at first sight during use, thereby facilitating quick positioning of the recognition area for the user. The fingerprint recognition module is partly arranged in the groove, and the distance between the fingerprint recognition module and a touch surface of the cover plate is reduced, thereby improving fingerprint sensitiveness and recognition accuracy of the fingerprint recognition module.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a fingerprint identification device, a touch screen and a terminal device. Background technique [0002] With the development of science and technology, smart terminals such as smart phones and tablet computers have been widely used in daily life. However, a large amount of important personal data are stored in smart terminals, and their security has become particularly important. At present, passwords are often used to protect smart terminal devices. Users need to enter a pre-set password to decode and use the smart terminal. This method has the possibility of password leakage or cracking. [0003] Human fingerprints are composed of uneven skin lines on the surface of fingers, which is a unique feature of the human body. The method of unlocking smart terminals by identifying fingerprints on the human body has high security. Therefore, fingerprint identification has become a metho...
