Embodiment Construction

[0025] 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.

[0026] 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 relates to a fingerprint module and an electronic device provided with the fingerprint module. A fingerprint chip arranged on the substrate; the shell comprises a first surface and a second surface, wherein the shell is provided with a mounting groove, and the fingerprint chip is accommodated in the mounting groove, wherein the housing further includes a contact surface connecting the groove wall of the mounting groove with the second surface, the contact surface extending obliquely from the groove wall to the second surface in a direction away from the mounting groove; the fingerprint module further includes a first filler glue connected between the outer periphery of the fingerprint chip and the substrate, the first filler glue including an inclined extension from a side wall of the fingerprint chip to an abutment surface; the contact surface is abutted against the abutment surface of the first filler. A fingerprint module in which the housing abuts against the contactsurface of the first filler through the contact surface, thereby avoiding interference of the included angle between the groove wall and the second surface with the first filler, thereby eliminating the metal ring surrounding the fingerprint chip to reduce the manufacturing cost of the fingerprint module and effectively reducing the thickness of the fingerprint module.

Description

technical field [0001] The invention relates to the field of fingerprint identification devices, in particular to a fingerprint module and electronic equipment provided with the fingerprint module. Background technique [0002] As an input device of human-computer interaction interface, touch screen is installed in various terminal devices and widely used in various fields. It plays an increasingly important role in people's life and social development. In order to realize the touch function of the screen, the touch screen is composed of a multi-layer structure, and the structure is relatively complicated. Moreover, since more and more personal information is stored during the use of the terminal equipment, a device is required to encrypt the terminal equipment. Since human fingerprints are formed by the joint action of genetics and the environment, their complexity is not only used for identification, but also has uniqueness and invariance. Therefore, fingerprint recogniti...
