Abstract
A color cathode ray tube comprises a faceplate having a predetermined pattern of phosphor deposits upon a target surface thereof. A color selection electrode assembly includes a frame which supports in tension a foil having an array of apertures related to the predetermined pattern of phosphor deposits on the faceplate. Means are disclosed for sealing the assembly between the faceplate and the rear envelope section of the tube to incorporate the color selection electrode assembly as an integral part of the cathode ray tube. Indexing means on the assembly and faceplate provide for repeated interregistered matings of the color selection electrode assembly with the faceplate. A method of utilizing the electrode assembly for screening the pattern of phosphor deposits on the faceplate is also disclosed.
