Fingerprint recognition device, touch screen with same and terminal device

Abstract

The invention discloses a fingerprint recognition device, a touch screen with the same and a terminal device. The fingerprint recognition device includes a cover plate component and a fingerprint recognition module. The cover plate component includes a first surface and a second surface, wherein a groove is formed in the second surface. The fingerprint recognition module includes at least one fingerprint sensor, the fingerprint sensing end of the fingerprint sensor is close to the second surface and used for sensing fingerprints on the first surface. The fingerprint recognition module is fixedly arranged in the groove, so the fingerprint sensor is placed at the position which is closer to fingers compared with the end surface of the second surface without the groove. According to the fingerprint recognition device, the groove is formed in the second surface and the fingerprint recognition module is installed in the groove, so the distance between the fingerprint recognition module and the first surface is reduced, sensitivity and accuracy of the fingerprint recognition module are improved, and fingerprints on the first surface can be recognized easily. Meanwhile, the area not provided with the groove is thick so the strength of the cover plate component can be ensured and the cover plate component is vulnerable to damage.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a fingerprint identification device, a touch screen and terminal equipment provided with the device. Background technique [0002] With the development of science and technology, the application of portable terminal devices in people's daily life is becoming more and more extensive, and their functions are becoming more and more powerful. But while the portable terminal device has more and more functions, it also carries a lot of private information. If these private information are leaked or stolen, it will bring inconvenience to the user and cause immeasurable losses. Therefore, it is very necessary to set up a security structure on the portable terminal. [0003] Then, for encryption using passwords and other methods, the user needs to remember the preset password, and there is also the possibility of the password being leaked or cracked. Human fingerprints are form...
