Embodiment Construction

[0024] Head-mounted displays and other devices can be used in virtual and augmented reality systems. These devices may include portable consumer electronics (e.g., portable electronics such as cell phones, tablets, glasses, other wearable devices), head-up displays in cockpits, vehicles, etc., display-based devices (projectors, televisions, etc.) Wait). Devices such as these may include displays and other optical components. A device configuration in which virtual reality and / or augmented reality content is provided to a user with a head-mounted display is described herein as an example. However, this is only exemplary. Any suitable means may be used to provide virtual reality and / or augmented reality content to users.

[0025] A head-mounted display worn on the user's head, such as a pair of augmented reality glasses, can be used to provide the user with computer-generated content overlaid on top of real-world content. Real world content can be directly viewed by the user...

Abstract

An electronic device, such as a head-mounted display, may have a display system that generates images. The display system may have one or more pixel arrays (26-1, 26-2), such as a liquid crystal on silicon pixel array. Images from the display system can be coupled into the waveguide (116) by an input coupler system (114X, 114Y) and can be coupled out of the waveguide in multiple image planes using an output coupler system (120X, 120Y). The input coupler system and the output coupler system may include single couplers, coupler stacks, and tiled coupler arrays. Multiplexing techniques, such as wavelength multiplexing, polarization multiplexing, time division multiplexing, multiplexing with image light including a range of different angular orientations, and / or tunable lens techniques, can be used to present images to the user in multiple image planes .

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application 15 / 894,736, filed February 12, 2018, and Provisional Patent Application 62 / 468,109, filed March 7, 2017, which are hereby incorporated by reference in their entirety This article. technical field [0003] This application relates generally to devices having displays, and more particularly to head-mounted displays. Background technique [0004] Head-mounted displays can be used to display virtual reality content and augmented reality content. Head-mounted displays showing augmented reality content can be overlaid with computer-generated images of real-world objects. Displays and optical systems can be used to generate images and to present those images to a user. [0005] However, if care is not taken, the components used to display content to the user in a head-mounted display can be unsightly and bulky, and may not exhibit the desired level of optical per...
