Embodiment Construction

[0074] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0075] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

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 and a fingerprint recognition module. The cover plate includes a first surface and a second surface, wherein a recognition groove is formed in the first surface and is used for positioning the fingerprint recognition area. The fingerprint recognition module includes a fingerprint sensor, wherein the fingerprint sensing end of the fingerprint sensor is close to the second surface and is used for sensing fingerprints on the first surface. The recognition groove formed in the first surface corresponds to the fingerprint sensor mounted on the second surface, so the distance between the fingerprint recognition module and the first surface can be reduced. When the fingerprint recognition module recognizes fingerprints, influence on sensitivity of the fingerprint sensor by the thickness of the cover plate is avoided, and recognition accuracy of the fingerprint recognition module is improved as the recognition groove is used for positioning. In addition, the area corresponding to the fingerprint recognition module in the first surface is arranged on the recognition groove and the thickness of other parts of the cover plate keeps unchanged, so the strength of the cover plate is ensured.

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] However, for encryption using passwords and other methods, the user needs to remember the preset password, and there is also the possibility that the password will be leaked or cracked. Human fingerprints a...
