Problems solved by technology

[0003] At present, there are mainly two ways to realize the fingerprint recognition technology under the screen. One way is to paste the optical fingerprint recognition module under the OLED display. This way is complicated, difficult, and easy to damage the OLED display. One way to achieve this is to prepare the display screen and the fingerprint recognition module together. This requires very high precision for the entire optical fingerprint recognition module in the mass production process, and the general processing technology basically cannot meet the actual needs.

Abstract

The invention discloses a fingerprint identification device and an electronic device that has a display screen, wherein the fingerprint identification device comprises a support plate for connecting amiddle frame of the electronic device in a fixed way; at least one fingerprint sensor chip disposed at the The upper surface of the support plate and under the display screen through the support plate. The at least one fingerprint sensor chip is configured to receive a fingerprint detection signal returned by reflection or scattering by a human finger above the display screen, and the fingerprintdetection signal is used to detect fingerprint information of the finger.

Description

technical field [0001] The embodiment of the present application relates to the technical field of fingerprint identification, and more specifically, to a fingerprint identification device and electronic equipment. Background technique [0002] With the rapid development of the terminal industry, people pay more and more attention to fingerprint recognition technology, and the practical application of more convenient off-screen fingerprint recognition technology has become the demand of the public. [0003] At present, there are mainly two ways to realize the fingerprint recognition technology under the screen. One way is to paste the optical fingerprint recognition module under the OLED display. This way is complicated, difficult, and easy to damage the OLED display. One way to achieve this is to prepare the display screen and the fingerprint identification module together. This requires very high precision for the entire optical fingerprint identification module in the mas...
