Abstract
(EN)
An optical lens (1), a fingerprint recognition module (4), a mobile terminal, and a manufacturing method for the optical lens (1). The optical lens (1) is arranged in the fingerprint recognition module (4) on the side of a screen (5), and the optical lens (1) is located on an optical path of a fingerprint image reflected by a reflector (2). The optical lens (1) comprises a light-shielding member (11), and the light-shielding member (11) is provided with at least one light-transmitting hole (111) for imaging. The optical lens (1) can be applied to an ordinary liquid crystal display screen, such that the ordinary liquid crystal display screen can make use of under-screen optical fingerprint technology.

L'invention concerne une lentille optique (1), un module de reconnaissance d'empreintes digitales (4), un terminal mobile, et un procédé de fabrication de la lentille optique (1). La lentille optique (1) est disposée dans le module de reconnaissance d'empreintes digitales (4) sur le côté d'un écran (5), et la lentille optique (1) est située sur un trajet optique d'une image d'empreintes digitales réfléchie par un réflecteur (2). La lentille optique (1) comprend un élément de protection contre la lumière (11), et l'élément de protection contre la lumière (11) est pourvu d'au moins un trou de transmission de lumière (111) destiné à l'imagerie. La lentille optique (1) peut être appliquée à un écran d'affichage à cristaux liquides ordinaire, de telle sorte que l'écran d'affichage à cristaux liquides ordinaire peut utiliser une technologie optique sous-écran des empreintes digitales.
