摘要：
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.
