Appl. No.:

16/813457

Inventors:

- Cupertino CA, US

Abstract:

An electronic device display and a display cover layer may be coupled to a housing. The display may have an array of pixels that are configured to emit light. One or more light redirecting elements may be incorporated into the electronic device that redirect and thereby change the direction of light rays emitted from peripheral pixels in the display. The light redirecting elements may be used to enlarge the effective size of the display, to create images on sidewall surfaces of the display cover layer, and/or to create diffuse glowing areas around the periphery of the device. Light redirecting elements may be formed as integral portions of a display cover layer, as laminated optical films on a display cover layer, or as coating layers on a display cover layer. Afocal optical systems may be formed by placing first and second light redirecting elements on opposing first and second sides of a display cover layer.

Abstract:

A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.
