Abstract
A portable short-focus near-eye display system is provided, which relates to the field of near-eye display technologies, and solves the problem of contradiction between optical performance and volumes in an existing AR technology. The system includes a microdisplay, an inner lens, and a concave partial reflector. The inner lens is closer to a pupil position, and the concave partial reflector is farther away from the pupil position. The microdisplay includes a rotating linear display or a transparent display. Through multiple reflections, an optical path is folded, so that a distance between a convex partial reflector and the concave partial reflector is shortened, and a thickness of glasses can be maximally reduced, thereby achieving thinning.
