Abstract
A light-based device may provide images and other light output to a user and may gather user input. The device may include a light guide array formed from a bundle of fibers. The light guide array may have an entrance surface that receives light emitted by a light-emitting device. The light-emitting device may include one or more light-emitting diodes and may be a display having an array of pixels. Light from the light-emitting device may be conveyed from the entrance surface to the exit surface by the light guide array. The exit surface of the light guide array may have a compound curvature. Optical structures may be formed over the exit surface. The light-based device may form light-field display, may form a touch sensor, may form a controller, and may form other structures.
