Abstract

The invention discloses a fingerprint module and a mobile terminal. The fingerprint module comprises a circuit board; a conduction chip which is arranged on the circuit board; a fingerprint identification chip which is arranged on the surface of the side, deviating from the circuit board, of the conduction chip, and a fingerprint identification chip which is electrically connected with the circuitboard through the conduction chip; and a packaging layer which wraps the conduction chip and the fingerprint identification chip. At the moment, the fingerprint identification chip and the conductionchip are stacked, so that most of the area of the fingerprint identification chip can be set as an identification area, the identification area is larger, and the fingerprint identification rate is improved. Besides, after the fingerprint identification chip and the conduction chip are stacked, the distance between the fingerprint identification chip and the surface of the packaging layer is smaller, that is, the thickness of the part, corresponding to the fingerprint identification chip, of the packaging layer is reduced, so that the fingerprint signal can reach the fingerprint identification area more effectively, and the fingerprint identification rate is improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint module and a mobile terminal. Background technique [0002] With the development of the mobile terminal industry, the constant pursuit of the ultimate appearance and high screen-to-body ratio is a major development direction at present, which can not only meet consumers' appearance needs, but also meet consumers' needs in audio-visual entertainment and other aspects. [0003] In order to increase the screen-to-body ratio of the mobile terminal, the fingerprint module can be arranged on the side of the mobile terminal. However, due to the limited thickness of the mobile terminal, the fingerprint recognition area of ​​the fingerprint module is small, resulting in a low fingerprint recognition rate of the fingerprint module of the fingerprint module. In addition, the encapsulation layer of the fingerprint module is relatively thick, so that the fing...
