Light guiding structure and display apparatus

Abstract

The present disclosure provides a light guiding structure including an optical waveguide for conducting image light, a coupling out grating on a surface of the optical waveguide, and a first lens on a side of the optical waveguide. The coupling out grating is used to coupling out the image light from the optical waveguide. The first lens is on an optical path of ambient light. The first lens includes a first optical surface away from the optical waveguide. The first optical surface is a free-form surface with asymmetric curvature and is used to adjust focusing position of the ambient light. A direction in which the first lens transmits the ambient light is consistent with a direction in which the coupling out grating couples out the image light. The present disclosure also provides a display apparatus.
