US 2021/0080680 A1 · Lens Mounting Systems for Electronic Devices

Abstract

An electronic device such as a head mounted device may have a display that displays an image for a user. Head-mounted support structures may be used to support the display and to support lenses. The head-mounted support structures may have one or more lens barrels or other support members. Each lens may have an optical surface and a side surface. Adhesive may be used to attach the lenses to the head-mounted support structures. A first portion of the adhesive may bond each lens to a first respective portion of a support member and a second portion of the adhesive may bond each lens to a second respective portion of the support member. The adhesive may be a non-silicone adhesive that fractures in bulk rather than failing at interfaces with the lens and support member. The elastic modulus of the adhesive may help avoid cracking and plastic deformation during drop events.

Dependent claims

A head-mounted device, comprising:

a display;
a lens through which the display is visible from an eye box, wherein the lens has an optical surface and a non-optical side surface;
a head-mounted support structure configured to support the display, wherein the head-mounted support structure has a support member configured to support the lens, wherein the support member has a first portion separated from the optical surface by a first gap and has a second portion separated from the non-optical side surface by a second gap;
and
adhesive having a first portion in the first gap and a second portion in the second gap.
