Abstract:
(EN) A fingerprint identification device, manufacturing method of a cover plate thereof, and electronic terminal. By providing several optical paths (2) in a main body (1) of a cover plate, a maximum amount of reflected light from an object to be identified can be transmitted to a light sensing region in an image identification chip (7) in a straight path. In this way, the image identification chip (7) receives light having the maximum intensity, facilitating formation of a clear image, and accordingly enabling high fingerprint identification accuracy of a fingerprint identification device. In addition, the fingerprint identification device can have a cover plate as thick as possible while meeting a signal penetration requirement, thus improving strength and reliability of the cover plate.
(FR) L'invention concerne un dispositif d'identification d'empreinte digitale, procédé de fabrication d'une plaque de couverture associée, et un terminal électronique. En fournissant plusieurs chemins optiques (2) dans un corps principal (1) d'une plaque de couverture, une quantité maximale de lumière réfléchie par un objet à identifier peut être transmise à une région de détection de lumière dans une puce d'identification d'image (7) dans un trajet droit. De cette manière, la puce d'identification d'image (7) reçoit de la lumière ayant l'intensité maximale, facilitant la formation d'une image nette, et permettant ainsi une précision d'identification d'empreinte digitale élevée d'un dispositif d'identification d'empreinte digitale. De plus, le dispositif d'identification d'empreinte digitale peut avoir une plaque de couverture aussi épaisse que possible tout en satisfaisant une exigence de pénétration de signal, améliorant ainsi la résistance et la fiabilité de la plaque de couverture.
(ZH) 一种指纹识别装置及其盖板的制造方法、电子终端,由于通过在盖板的本体(1)中设置若干个光通路(2),以使被识别对象反射的光线尽可能多地直线传输到图像识别芯片(7)中的感光区域,以使图像识别芯片(7)接收到的光线的强度最大,有利于形成清晰的图像,从而实现提高指纹识别装置的指纹识别精度。此外,指纹识别装置在满足信号穿透率的前提下,盖板的厚度可以尽可能地厚,以进一步加强盖板的强度和可靠性。
