Beam scanned display apparatus and method thereof
Generally, display systems may be employed in cinema and exhibition applications. Laser scanned display systems may be enabled such that the display systems may display three dimensional (“3D”) content. One example of a display system may include a diffusive screen which may be a transmissive diffuser and at least a light engine or an array of light engines, in which the light engine or array of light engines may include at least a light source, beam combining optics which may combine colors into at least one of a single beam or closely spaced beams, and at least a scanning system which may steer the beam to a desired location on the diffusive screen.
