Abstract
Methods and systems for improving imaging quality and power efficiency of scanning beam display systems using fluorescent screens are disclosed. In various embodiments, beam shaping mechanisms for maximizing overlap between the beam cross-section and the florescent element corresponding to each color sub-pixel of the screen, as well as pulse width and timing adjustments, are introduced to reduce imaging noise and improve power efficiency of the display system.
