Embodiment Construction

[0012] Head-mounted devices and other devices can be used in virtual reality and augmented reality systems. These devices may include portable consumer electronic devices (e.g., portable electronic devices such as mobile phones, tablets, glasses, other wearable devices), head-up displays in cockpits, vehicles, etc., display-based devices (projectors, televisions) machine, etc.). Devices such as these may include transparent displays and other optical components. Device configurations in which virtual reality and / or augmented reality content are provided to a user with a head-mounted display are described herein as examples. However, this is only exemplary. Any suitable device may be used to provide virtual reality and / or augmented reality content to users.

[0013] Head-mounted devices, such as augmented reality glasses, worn on the user's head may be used to provide the user with computer-generated content overlaid on top of real-world content. Real-world content can be v...

Abstract

The disclosure relates to a head-mounted device with an adjustable opacity system. The invention discloses a head-mounted device which may have a transparent display. The transparent display may be formed from a display unit that provides images to a user through an optical coupler. A user may view real-world objects through the optical coupler while control circuitry directs the transparent display to display computer-generated content over selected portions of the real-world objects. The head-mounted display may also include an adjustable opacity system. The adjustable opacity system may include an adjustable opacity layer such as a photochromic layer that overlaps the optical coupler and a light source that selectively exposes the adjustable opacity layer to ultraviolet light to controlthe opacity of the adjustable opacity layer. The adjustable opacity layer may block or dim light from the real-world objects to allow improved contrast when displaying computer-generated content overthe real-world objects.

Description

technical field [0001] The present invention relates generally to devices having displays, and more particularly to head-mounted displays. Background technique [0002] Head-mounted displays can be used to display virtual reality and augmented reality content. Head-mounted displays that display augmented reality content superimpose computer-generated images on top of real-world objects. If you're not careful, it can be difficult to view computer-generated images against real-world objects, real-world objects can distract the viewer, or there can be other problems with the displayed content. Contents of the invention [0003] Electronic devices such as head mounted devices may have transparent displays. The transparent display may be formed from a display panel that provides an image to a user through an optical coupler. A user can view the real-world object through the optical coupler, while control circuitry instructs the transparent display to display computer-generat...
