Abstract

The embodiment of the present application provides a fingerprint identification device with a smaller thickness and a better imaging effect. The fingerprint recognition device includes: an optical path guiding structure disposed between the display screen and the optical fingerprint sensor for guiding an optical signal obliquely incident on the finger above the display screen and reflected by thefinger at a preset angle to an optical fingerprint sensor, disposed under the optical path guiding structure for detecting the received optical signal.

Description

technical field [0001] The present application relates to the field of information technology, and more specifically, to a fingerprint identification device and electronic equipment. Background technique [0002] Capacitive fingerprint recognition technology faces the limitation of penetrating ability, and it is difficult to apply to the fingerprint recognition system under the screen, while the optical fingerprint recognition technology breaks through the limitations of the thickness of the display screen and glass, so it has a good application prospect. [0003] In the optical fingerprint identification device, the optical path guide structure is usually used to guide the reflected light signal carrying the fingerprint information to the optical fingerprint sensor for collection, and the legitimacy of the user identity is confirmed by comparing the collected information with the pre-registered and stored fingerprint information. In order to meet the thinning requirements o...
