ABSTRACT:
An improved projection color television system in which an optical radiation pattern, which is primary color coded, is generated by cathode ray tube means and optically coupled by projection optics to a projection screen display means. The projection screen display means includes a support substrate which has a plurality of phosphor areas disposed on the substrate with the phosphors areas including at least one primary color emissive organic phosphor composition. The primary color emissive organic phosphor area is optically registered via the projection optics to the corresponding primary color coded portion of the optical radiation pattern generated by the cathode ray tube means. The projection screen itself is thus emissive of the primary color visible radiation.
