A multi-color flat panel display of individually manufactured components operatively assembled to produce a multi-color image from a monochromatic source, the individually manufactured components include a color output assembly for converting a photon pattern produced by the monochromatic source to a corresponding electron pattern for excitation of color phosphors to display a corresponding optical image in color; and an optical collimator for preventing cross-talk between input section pixels of the monochromatic source and unassociated output section pixels of the color output assembly.
