Abstract

Systems, devices, and methods for transparent displays that are well-suited for use in wearable heads-up displays are described. Such transparent displays include one or more scanning projector(s) that is/are mounted on or proximate the lens portion(s) thereof, directly in the field of view of the user. Each scanning projector includes a respective light source that sequentially generates pixels or other discrete portions of an image and a respective dynamic optical beam-steerer that controllably steers the modulated light directly towards select regions of the eye of the user. Successive portions of the image are generated in rapid succession until the entire image is displayed to the user by projection directly onto the eye of the user from one or more point(s) within the user's field of view.

Claims12

Dependent claims

A wearable heads-up display comprising:

a support structure to be worn on a head of a user;
a first transparent element that is physically coupled to the support structure, wherein the first transparent element is positioned within a field of view of at least one eye of the user when the support structure is worn on the head of the user;
a first light-emitting element physically coupled to the support structure and positioned proximate a periphery of the first transparent element;
and
a first set of static light-refractors, each static light-refractor in the first set of static light-refractors carried by the first transparent element in the field of view of the at least one eye of the user when the support structure is worn on the head of the user, wherein in use at least one static light-refractor in the first set of static light-refractors receives light emitted by the first light-emitting element through the periphery of the first transparent element and refracts the light emitted by the first light-emitting element towards the at least one eye of the user.
