Abstract

The embodiment of the invention provides a fingerprint acquisition device, a fingerprint identification method and a terminal, and belongs to the technical field of intelligent identification. The fingerprint acquisition device is applied to the terminal with a screen, and comprises a light ray adjusting mechanism which is used for adjusting the light path of detection light emitted by a light source according to the position of a finger contacting the screen and adjusting the light path of reflected light obtained by reflecting the detection light through the finger; and a fingerprint sensorwhich is used for sensing the reflected light adjusted by the light adjusting mechanism and acquiring fingerprint information according to the reflected light. According to the embodiment of the invention, the effective fingerprint acquisition area can be expanded.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent identification, and in particular, to a fingerprint acquisition device, a fingerprint identification method, and a terminal. Background technique [0002] In order to protect the information security in the terminal and facilitate the user to quickly unlock the terminal lock screen, fingerprint unlocking is a necessary design on the terminal. The commonly used fingerprint recognition technology in the past is based on semiconductor silicon capacitance effect technology, but this type of fingerprint recognition module needs to occupy a part of the terminal area alone, and cannot be integrated with the display screen. Therefore, with the development of full-screen terminals, optical fingerprint recognition technology is gradually becoming popular. The optical fingerprint identification module can be arranged under the display screen without affecting the display of the...
