Abstract

A METHOD FOR MANUFACTURING FLUORESCENT LAYERS FOR A CATHODE RAY TUBE (CRT) AND A CRT ADOPTING THE FLUORESCENT LAYERS. IN THE CRT HAVING A FACE PLATE WITH AN INNER SURFACE ONTO WHICH CATHODE RAY IS RADIATED, AND FIRST-, SECOND- AND THIRD- COLOR FLUORESCENT LAYERS FORMED ON THE INNER SURFACE OF THE FACE PLATE, A FIRST-COLOR FILTER LAYER IS FORMED BETWEEN THE INNER SURFACE AND THE FIRST- COLOR FLUORESCENT LAYER, AND THE SECOND- AND THIRD- COLOR FLUORESCENT LAYERS CONTAINS PIGMENT ED SECOND- AND THIRD- COLOR PHOSPHORS EACH. THEREFORE, FORMING PROCESS OF A PROTECTIVE RESIN LAYER. IS NOT NECESSARY AND THE NUMBER OF PROCESSES REQUIRED IS REDUCED COMPARED TO THE CASE OF FORMING RED, GREEN AND BLUE FILTER LAYERS, SO THE ENTIRE MANUFACTURING PROCESS IS SIMPLIFIED, THUS LOWERING THE MANUFACTURING COST. IN ADDITION, LUMINANCE AND CONTRAST CHARACTERISTICS OF THE CRT ADOPTING THE FLURESCENT LAYERS MANUFACTURED BY SUCH METHOD ARE ENCHANCED.(FIG. 1)
