Abstract

The invention provides a fingerprint module and an electronic device. The fingerprint module comprises a fingerprint chip and a hollow frame, wherein the fingerprint chip comprises a first surface, a second surface and side surfaces, wherein the first surface and the second surface are arranged oppositely, and the side surfaces intersect with the first surface and the second surface respectively and incline relative to a perpendicular line perpendicular to the first surface; the frame is used for accommodating the fingerprint chip and comprises an inner surface, and the inner surface of the frame is close to the side surfaces of the fingerprint chip and inclines relative to the perpendicular line perpendicular to the first surface; an included angle between the inner surface of the frame and each side surface of the fingerprint chip is smaller than or equal to a preset threshold.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fingerprint module and an electronic device. Background technique [0002] Fingerprint recognition technology is a technology used to prevent security incidents through user registration and authentication procedures. Fingerprint recognition technology is usually applied to personal and organizational network defense, data protection, computer or mobile device security control, etc. Usually, a computer or mobile device is equipped with a fingerprint identification chip to detect the user's fingerprint image, and judge whether the user who is using the computer or mobile device is allowed to operate according to the fingerprint information corresponding to the user's fingerprint image. The computer or mobile device. In the prior art, the gap between the fingerprint module chip and the frame body is relatively large when assembling, and dust and the like may easily fall int...
