Abstract
An optical waveguide plate (), a frame, and smart glasses, which relate to the technical field of smart glasses. The optical waveguide plate () includes a waveguide substrate (), a coupling-in region (), and a coupling-out region (); where the coupling-in region () and the coupling-out region () are disposed on the waveguide substrate (), the coupling-in region () is configured to couple light into the waveguide substrate (), and the coupling-out region () is configured to couple out the light propagating within the waveguide substrate (); and a bottom edge of the coupling-out region () is located above a horizontal bisector of the optical waveguide plate (), or the bottom edge of the coupling-out region () is entirely or partially flush with the horizontal bisector of the optical waveguide plate (). The problem that smart glasses are unsuitable for extended use by a user due to the occurrence of rainbow patterns on the smart glasses is solved.
