Filed:

Mar 9, 2020

Appl. No.:

16/813457

Inventors:

- Cupertino CA, US
John N. Border - Campbell CA, US
Victoria C. Chan - Sunnyvale CA, US

International Classification:

G06F 1/16
G02B 5/02
G02B 27/30
G02B 1/14

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.

International Classification:

G02B 3/12

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.

Abstract:

A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the device on the head of the user. A non-removable lens system may be supported by the head-mounted support structures. The head-mounted support structures may be configured to receive a removable supplemental lens system. The removable supplemental lens system may be used to customize the head-mounted display to accommodate the user's vision. Information such as information on the optical characteristics of the removable supplemental lens system and the user's eyeglass prescription may be stored in the removable supplemental lens system using bar codes, text, programmable memory, or other data storage. When the removable supplemental lens system is installed in the head-mounted device, control circuitry in the head-mounted device may retrieve the stored information. A gaze tracker system or other sensors may be used in retrieving the stored information.
