Abstract

The invention discloses a fingerprint module, a display device and a mobile terminal. The fingerprint module comprises a supporting piece and a fingerprint chip, wherein the supporting piece comprises a main body and an extending piece extending from the peripheral side of the main body; the main body is provided with an accommodating groove; the extending direction of the extending piece is vertical to the opening direction of the accommodating groove; the extending piece is used for being attached to the back surface of a display screen; the fingerprint chip is fixed in the accommodating groove; and the fingerprint chip is parallel with the extending piece. Through extending the extending piece from the peripheral side of the main body of the supporting piece and enabling the extending piece to be attached to the back surface of the display screen, the attaching area between the fingerprint module and the display screen can be expanded; as the extending piece is parallel with the fingerprint chip, the parallelism between the fingerprint chip of the fingerprint module and the display screen is further ensured; the fingerprint chip sensing signal transmitting and receiving accuracy is improved, the fingerprint acquisition efficiency is enhanced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a fingerprint module, a display device and a mobile terminal. Background technique [0002] At present, the front of the mobile phone is often equipped with a fingerprint recognition module and a display screen, and the fingerprint recognition module is arranged outside the display screen, which is convenient for users to operate without affecting the display screen. However, under this structure, the fingerprint recognition module reduces the screen-to-body ratio of the mobile phone, so the superposition of the fingerprint recognition module and the display screen can increase the screen-to-body ratio of the mobile phone. However, in the superimposed structure of the fingerprint identification module and the display screen, the parallelism between the fingerprint chip of the fingerprint identification module and the display screen cannot be guaranteed, resulting in inaccurate...
