Problems solved by technology

However, there is no shading member around the light source of this type of fingerprint recognition device disclosed in the prior art, so that the luminous flux irradiated to the panel by the light source of the fingerprint recognition device is small (light leakage). The light emitted by the light source interferes with each other so that the recognition performance of the fingerprint recognition device is greatly weakened

Abstract

The invention provides a fingerprint recognition device and a terminal with the fingerprint recognition device, wherein the fingerprint recognition device comprises a support, a fingerprint recognition chip assembled under the support, at least one light source fixed on the periphery of the support and a cushion plate supported on the surface of the support, the cushion plate is located on the periphery of the light source, and the cushion plate is used to isolate external stray light along a side edge direction of the fingerprint recognition device from the light source; and the cushion plate is disposed to isolate the external stray light along the side edge direction of the fingerprint recognition device from the light source and hinder adverse influences brought by the external stray light to the fingerprint recognition device, and the light source is embraced in the cushion plate to reduce losses of light rays emitted by the light source and potentially increase luminous flux emitted by the light source into a light guide plate so as to better realize a fingerprint recognition function. In addition, setting of the cushion plate makes for immobilization and stabilization among a conduit plate, a cover plate and the support and enhances structural stability and overall strength of the whole fingerprint recognition device.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification device and a terminal provided with the fingerprint identification device. Background technique [0002] For the prior art, please refer to the Chinese Utility Model Patent Announcement CN204791058U, which discloses a fingerprint identification device installed on the panel of the terminal.
