Abstract
A broadband electromagnetic wave beam is projected from a broadband wave source (301). The wave beam is separated by an element (306) into narrowband wavelength beams. The narrowband beams are directed across a predetermined area (312). A narrowband wavelength beam corresponding to a desired pixel wavelength is selected and displayed on a display surface (318).
