  • Publication number: 20200177851
    Abstract: A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

  • Patent number: 10303416
    Abstract: In one embodiment, the modular display includes aggregates of individual panel tiles arranged between two large plastic sheets. The footprint of the large plastic sheet sandwich becomes the dimension of the display screen. The tilettes are phosphor emission panels with a full complement of emittable pixels. By separating the tilettes from the final full dimension sheet, the tilettes can be manufactured in transportable sizes and the outer full dimension sheets can be rolled for easy transport to the final install location.

  • Patent number: 9729837
    Abstract: Systems and techniques for scanning-beam display are provided to use local dimming on the optical energy of at least one optical beam to minimize the non-uniform image brightness across the screen. This local dimming during the beam scanning can be achieved by adjusting optical energy of at least one optical beam during the scanning based on (1) the location of the scanning optical beam and (2) the predetermined distortion information at the location.
