Abstract:
Augmented reality and virtual reality display systems and devices are configured for efficient use of projected light. In some aspects, a display system includes a light projection system and a head-mounted display configured to project light into an eye of the user to display virtual image content. The head-mounted display includes at least one waveguide comprising a plurality of in-coupling regions each configured to receive, from the light projection system, light corresponding to a portion of the user's field of view and to in-couple the light into the waveguide; and a plurality of out-coupling regions configured to out-couple the light out of the waveguide to display the virtual content, wherein each of the out-coupling regions are configured to receive light from different ones of the in-coupling regions. In some implementations, each in-coupling region has a one-to-one correspondence with a unique corresponding out-coupling region.
