Abstract: A method for operating a MEMS system having a projection unit for providing an image via a light beam, and a deflecting unit for the two-dimensional deflection of the at least one light beam. The method includes: driving the deflecting unit via a reference signal, so that the deflecting unit periodically deflects a light beam at least two-dimensionally, measuring a controlled variable of the deflecting unit that corresponds to an actual position of the deflected light beam, ascertaining a current deviation of the controlled variable from a target variable that corresponds to a target position of the light beam, calculating a compensating variable based on the ascertained deviation, controlling the deflecting unit and/or controlling the projection unit based on the calculated compensating variable for reducing the deviation of the light beam from the target position. The compensating variable is additionally calculated based on an earlier deviation in an earlier period.

Abstract: Light of a virtual image of image content is projected by an optical subsystem to an eye location. The optical subsystem collects the light from a first aperture to the eye location. The virtual image is of an object located within a second aperture, wherein the first and second apertures are not collocated. In an associated method, a flat-panel image-display modulator within the second aperture imparts image content of the virtual image onto light generated by a source of light within the first aperture.

Abstract: An information provision device, information provision method, and a non-transitory recording medium storing a program for causing a computer to execute the information provision method. Each of the information provision device and the information provision method includes projecting an image light to a light transmission member to display a for-driver information image indicating for-driver information to be provided to a driver of a mobile object in a prescribed display area, and displaying at a first point where a normal for-driver information image is displayed a priority for-driver information image in place of the normal for-driver information image, where the displaying includes displaying the normal for-driver information image at a second point different from the first point for at least some of a period during which the priority for-driver information image is displayed at the first point.

Abstract: A display system includes an integrated laser and modulator device and a display assembly. The integrated laser and modulator device includes a laser component configured to facilitate light emission responsive to applied current and a modulator component configured to selectively modulate light responsive to applied signal. The modulator component is integrally coupled to the laser component via a bridging structure that intervenes between the laser component and the modulator component. At least a portion of the bridging structure facilitates power reflectivity into a laser cavity of the laser component. The bridging structure facilitates transmission of light emitted by the laser component into the modulator component for modulation by the modulator component to provide modulated light. The display assembly is configured to direct the modulated light provided by the integrated laser and modulator device to illuminate pixels to form an image.

Abstract: A display system may display image frames. The system may include a scanning mirror and an array of staggered light emitting elements. The light emitting elements may emit image light and collimating optics may direct the light at the scanning mirror, which reflects the image light while rotating about an axis. Control circuitry may selectively activate the light emitting elements across tangential and sagittal axes of the image frame while controlling the scanning mirror to scan across the sagittal axis.
