摘要： A device may include an electronic display to display image frames. The display may include illuminators that generate light and mirrors that selectively direct the light to pixel locations based bitplanes that set the arrangement of the mirrors. Additionally, the device may include duty cycle balancing circuitry that generates and provides duty cycle balancing signals to the electronic display. In response to the duty cycle balancing signals, the electronic display is implements balancing on bitplanes during at least a first portion of off periods during the image frames and implements balancing off bitplanes during at least a second portion of the off periods such that, in the aggregate, a ratio of respective on times of the mirrors to respective off times of the mirrors is balanced across the image frames during the off periods.

摘要： A waveguide display includes a light source, a conditioning lens assembly, a scanning mirror assembly, and a controller. The light source includes a plurality of source elements that are configured to emit image light in accordance with scanning instructions. The conditioning lens assembly transmits conditioned light based in part on the image light. The scanning mirror assembly scans the conditioned image light to particular locations as scanned image light in accordance with scanning instructions. The output waveguide includes an input area and an output area, receives the scanned image light emitted from the scanning mirror assembly at the input area, and outputs the expanded image light from a portion of the output area based in part on a direction of the expanded light output from the scanning mirror assembly. The controller generates the scanning instructions and provides the scanning instructions to the light source and the scanning mirror assembly.

摘要： A method for determining an orientation of a photosensor of a controller with respect to a projector is described. The method includes generating, by a beam generator of the projector, a beam. The method further includes modifying a direction of travel of the beam using a micro-electro-mechanical systems (MEMS) mirror that moves in a pattern, detecting the beam, calculating a time at which the beam is detected, and determining based on the pattern and the time an orientation of the beam to determine the orientation of the photosensor.

摘要： A display engine includes light emitting elements, an optical subsystem to produce a single collimated beam of light from the light emitted by the light emitting elements, one or more image producing MEMS mirrors, one or more image reprojecting MEMS mirrors, and a controller. One of the image producing MEMS mirror(s) is positioned to reflect the single beam of light produced by the optical subsystem. The controller controls the image producing MEMS mirror(s) and the image reprojecting MEMS mirror(s). The image reprojecting MEMS mirror(s) is/are controlled and is/are positioned relative to the image producing MEMS mirror(s) and relative to input-coupler(s) of optical waveguide(s) so that a pupil corresponding to a scanned image that the image producing MEMS mirror(s) project onto one of the image reprojecting MEMS mirror(s), is reprojected by the image reprojecting MEMS mirror(s) onto the input-coupler(s) of the optical waveguide(s) and thereby coupled into the optical waveguide(s).

摘要： An image projection device includes: a light source for emitting a light beam; a mirror unit that includes a mirror for reflecting the beam and projects an image onto a surface by rotating the mirror about a rotational axis to scan the beam; and a controller for determining, according to a function representing a relationship between a shift amount, an emitting time of the beam, a position on the surface irradiated by the beam emitted at the emitting time, and a shift angle of the mirror from its position when it is not driven, the emitting time corresponding to a target position. The shift amount is a shift amount of a position of the beam incident on the mirror or a shift amount of a position of the source relative to an optical axis of light incident on the mirror without the shift amount and perpendicularly intersecting the rotational axis.
