  • Patent number: 11979689
    Abstract: A projection system and a projected image stacking method are provided, in the method, an individual representative position of each captured image is identified, wherein the captured images are obtained by respectively capturing an area projected by multiple projectors, and each individual representative position is related to image content projected by each projector. A common representative position is set in the area. A projection lens of each projector is shifted according to a distance difference between each individual representative position and the common representative position. In this way, the projection lens is quickly shifted, and is further applied to stacking operations. The operation of multiple projectors is as convenient as the operation of a single projector based on control of a remoter or keys of a projector control interface.

  • Patent number: 11966057
    Abstract: Display systems, such as near eye display systems or wearable heads up displays, may include a laser projector having an optical switch assembly disposed an at input to an optical scanner of the laser projector. The optical switch assembly includes at least one optical switch, and a controller selectively modifies the orientation of each optical switch to selectively change an angle at which laser light is directed onto a scan mirror of the optical scanner. Changing this angle shifts the scan region over which the scan mirror scans the laser light and, relatedly, shifts a region of a field of view of the display. In some embodiments, the controller is configured to modify the optical switch orientation(s) to correct non-idealities in the angle of the laser light.

  • Patent number: 11964429
    Abstract: A method and an apparatus pertaining to recycling and reuse of unwanted light in additive manufacturing can multiplex multiple beams of light including at least one or more beams of light from one or more light sources. The multiple beams of light may be reshaped and blended to provide a first beam of light. A spatial polarization pattern may be applied on the first beam of light to provide a second beam of light. Polarization states of the second beam of light may be split to reflect a third beam of light, which may be reshaped into a fourth beam of light. The fourth beam of light may be introduced as one of the multiple beams of light to result in a fifth beam of light.

  • Patent number: 11940625
    Abstract: A display includes a light-guide optical element (LOE) (20) and a projector arrangement (10a) for injecting an image into the LOE so as to propagate within the LOE by internal reflection at a pair of major faces. The image is coupled out from the LOE by a coupling-out arrangement, exemplified here as internal partially-reflecting surfaces (22b). The image is coupled out from the LOE in a direction away from the eye of the observer (24b), and a reflector (30) reflects the coupled-out image back through the LOE (32), towards the eye of the observer (26). Reflector (30) is preferably a selective partial reflector, and may be convex to provide a desired apparent image distance.

  • Patent number: 11932107
    Abstract: A display surface of a self-luminous screen element is divided into first and second display regions by a bend region. A selective shielding unit transmits light from the screen element along a preferred direction and blocks light along a blocking direction and/or deflects light from the blocking direction. When installed in a motor vehicle, the display device faces a surface region at a distance from the screen element on which a reflection of the display content displayed on the second display region is visible from a predetermined viewing point. In this case, the preferred direction of the selective shielding unit in the second display region is oriented toward the surface region and the blocking direction in the second display region is oriented toward the predetermined viewing point.
