Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the fingerprint identification module and the touch screen based on fingerprint identification will be more fully described below with reference to the relevant drawings. The preferred embodiment of the fingerprint identification module is given in the accompanying drawings. However, the fingerprint identification module can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the fingerprint identification module more thorough and comprehensive.

[0048] 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 m...

Abstract

A fingerprint recognition module includes a cover plate, a fingerprint sensor and a control element. The cover plate includes a first surface and a second surface opposite to the first surface. The fingerprint sensor includes a fingerprint sensing picture formed on one side of the second surface of the cover plate, wherein the fingerprint sensing picture is configured to sense fingerprints of user fingers and generate fingerprint sensing signals. The control element is electrically connected with the fingerprint sensor and is configured to process the fingerprint sensing signals. The invention further discloses a touch screen based on fingerprint recognition. The fingerprint recognition module and the touch screen based on fingerprint recognition can avoid stress concentration and strength reduction caused by tapping of the appearance of the mobile terminal, facilitate touch and watching by users, ensure the fingerprint recognition module to be thin, and are favorable for improving fingerprint recognition accuracy of the fingerprint recognition module. In addition, other parts of the fingerprint recognition module like the arrangement position of the control chip are more flexible; the fingerprint recognition picture can be formed together with the touch images so processes are saved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification module and a touch screen based on fingerprint identification. Background technique [0002] Fingerprint recognition refers to the technology of identity identification by comparing the detailed feature points of different fingerprints. With the development of science and technology, the application fields of fingerprint recognition are becoming more and more extensive. In addition to access control and attendance systems, devices with touch screens such as laptops and mobile phones have realized the fingerprint recognition function. [0003] However, in order to realize the fingerprint identification function, the traditional fingerprint identification module is generally installed under the cover as a separate part. [0004] For a terminal device with a fingerprint recognition module installed, the fingerprint recognition module ...
