See full text

An ultra-thin lens for augmented reality (AR) display includes: a primary lens, an intermediate lens, and a secondary lens. After entering the primary lens, image light undergoes two total reflections, then enters the intermediate lens and is partially reflected, then is directed to a human eye through the intermediate lens and the primary lens. The secondary lens is configured on the other side of the intermediate lens, and environmental light is directed to the human eye through the secondary lens, the intermediate lens, and the primary lens. According to the ultra-thin lens, total reflection and light splitting functions of the image light are realized respectively through the primary lens and the intermediate lens, so that the entire lens has a thin and light profile.
