OPTICAL LENS AND VIRTUAL IMAGE DISPLAY MODULE

摘要

An optical lens, adapted for transmitting an image light beam generated by an image display unit to at least one eye of a user. The optical lens includes a reflecting unit, an L-type lens and a diffractive optical element. The reflecting unit, the L-type lens and the diffractive optical element are disposed on a transmission path of the image light beam. The L-type lens has a first portion and a second lens portion integrally molded with each other. The first lens portion is disposed between the image display unit and the reflecting unit. The second lens portion is disposed between the reflecting unit and the eye. The image light beam is transmitted to the eye through the first lens portion, the reflecting unit, the second lens portion and the diffractive optical element to provide a virtual image. Besides, a virtual image display module is also provided.
