Abstract

The present invention provides an optical fingerprint assembly and a mobile terminal. The optical fingerprint assembly includes: a transparent cover, a light-emitting display and a photosensitive element. The light-emitting display is located between the transparent cover and the photosensitive element. A collimation layer is provided between the transparent cover and the photosensitive element, and the collimation layer is used to convert the light emitted from the transparent cover toward the end face of the photosensitive element into collimated light, and conduct it to the The photosensitive element; wherein, the light is emitted by the light-emitting display screen. This can effectively improve the clarity of fingerprint recognition.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical fingerprint component and a mobile terminal. Background technique [0002] With the continuous development of technology, the screen-to-body ratio of mobile terminals such as mobile phones is getting higher and higher, and mobile terminals with full screens have become a development trend. For the fingerprint identification of full-screen mobile terminals, conventional capacitive fingerprints cannot penetrate the cover glass with a thickness of more than 0.5 mm, so they no longer adapt to the development trend of full-screen mobile terminals, and optical fingerprints with good penetration It has become a new technical direction. [0003] At present, for the design of fingerprint identification for full-screen mobile terminals, optical fingerprint photosensitive elements are generally designed to be stacked under the display screen. In the practical application ...
