UNDER-SCREEN OPTICAL FINGERPRINT DEVICE AND HANDHELD DEVICE HAVING THREE-DIMENSIONAL FINGERPRINT ANTI-COUNTERFEIT SENSING FUNCTION

摘要

Provided is an under-screen optical fingerprint device (1) having a three-dimensional fingerprint anti-counterfeit sensing function, used for sensing a fingerprint of a specific object, said under-screen optical fingerprint device (1) comprising: a structured light output device (30), used for projecting structured light (L4) onto the specific object; and an optical sensing device, comprising a second optical input device (40), used for receiving the structured light reflected by the specific object (L41) to obtain third-dimensional information of the fingerprint of the specific object.
