COLOR TELEVISION TUBE WITH PHOSPHORS ON EXTERIOR SURFACE OF FACEPLATE

摘要

A color television picture tube of the triad phosphor array type in which a single layer of cathodoluminescent absorptive radiation emissive material is disposed on the interior surface of the tube faceplate. Radiation collimating means are associated with the tube faceplate, and at least two different primary color emissive materials are disposed on the exterior surface of the faceplate. The exterior disposed primary color emissive materials are absorptive of the radiation emitted by the internallydisposed material and excited to emission thereby.
