Wearable display apparatus

摘要

A display apparatus includes a planar waveguide optical element, a projection optical system, and a microdisplay device. By including free-form optics and waveguide technology, the volume and weight of the display apparatus can be reduced, and an optical system can be realized with improved image quality, structure, and performance parameters.

主权项

1. A wearable display apparatus, comprising:
a waveguide optical device; a projection optical system including an optical free-form surface; and a microdisplay device; wherein the projection optical system is coupled to the waveguide optical device through an inclined optical path; wherein the projection optical system comprises a prism having at least one optical free-form curved surface; and wherein the free-form surface prism comprises at least three free-form curved surfaces, with non-overlapping exit pupil positions in two orthogonal directions, with a thickness ≦5 mm, and a width ≦10 mm.
