Fingerprint identification device, touch screen and terminal equipment

Abstract

The invention discloses a fingerprint recognition device. The fingerprint recognition device comprises a cover plate element and a fingerprint recognition module, wherein the fingerprint recognition element comprises a first portion and a second portion which are connected with each other; the first portion is an integrated mechanism; the second portion comprises a base plate and a cover plate which are stacked together; a touch groove is formed in one side, which is far away from the base plate, of the cover plate; the fingerprint recognition module comprises at least one fingerprint sensor; at least one groove is formed in the second portion of the cover plate element; at least one part of the fingerprint recognition module is accommodated in the grooves, so that the fingerprint sensors are arranged at suitable positions, and the distances from the positions to fingers of a user are shorter than the distance from the base plate to the fingers of the user; and the position of the touch groove corresponds to the positions of the grooves. By the cover plate and the base plate, the overall strength of a touch screen is enhanced through the base plate when the cover plate is thin. By the grooves and the touch groove corresponding to the grooves, the distance from the fingerprint recognition module to an end surface of the cover plate is reduced, and the fingerprint sensitiveness and the recognition accuracy of the fingerprint recognition module are improved.

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...

Problems solved by technology

[0005] Based on this, it is necessary to provide a fingerprint identification device, a touch screen and a terminal device with improved sensitivity and increased identification efficiency without affecting the strength for the problem that the fingerprint sensitivity is not high and the identification efficiency and strength of the fingerprint identification device cannot be guaranteed at the same time.
