Abstract

Embodiments of this disclosure provides systems and methods for displays. In embodiments, a display system includes a frame, an eyepiece coupled to the frame, and a first adhesive bond disposed between the frame and the eyepiece. The eyepiece can include a light input region and a light output region. The first adhesive bond can be disposed along a first portion of a perimeter of the eyepiece, where the first portion of the perimeter of the eyepiece borders the light input region such that the first adhesive bond is configured to maintain a position of the light input region relative to the frame.
