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.

Abstract: An open cell foam is used to create a seal between a camera and a shell piece. The shell piece, camera, seal and a transparent window form a closed front cavity. Because the cavity is closed, dust can remain away from a lens of the camera.

Abstract: An example head-mounted display device includes a light projector, an optical assembly arranged to direct light from a light projector to a user, and an actuator module. The optical assembly includes a variable focus lens assembly including a rigid refractive component, a shaper ring defining an aperture, and a flexible lens membrane between the shaper ring and the rigid refractive component and covering the aperture. The refractive component, the shaper ring, and the lens membrane are arranged along an axis. The refractive component and the lens membrane define a chamber containing a volume of fluid. The actuator module is configured to adjust an optical power of the variable focus lens by moving the shaper ring relative to the refractive component along the axis, such that a curvature of the lens membrane in the aperture is modified.
