Abstract

본 발명은 컬러 음극선관에 포함되는 형광막의 형성방법에 관한 것으로, 형광막을 이루는 형광입자의 크기를 다르게 하여 혼합한 형광분말을 사용하여 형광막을 형성하므로써 화질을 개선시킨 음극 선관의 형광막 제조방법에 관한 것이며, 이를 위한 음극선관의 형광막을 형성하는 방법에 있어서는 상기 형광막을 구성하는 대립자 형광체와, 상기 대립자 보다 작은 크기의 소립자 형광체를 소정의 비로 혼합하여 된 형광 분말로 형광막을 형성하는 것을 특징으로 한다.The present invention relates to a method of forming a fluorescent film included in a color cathode ray tube, and to a method of manufacturing a fluorescent film of a cathode ray tube having an improved quality by forming a fluorescent film using a fluorescent powder mixed with different sizes of fluorescent particles forming a fluorescent film. In the method for forming a fluorescent film of the cathode ray tube for this purpose, the fluorescent film is formed of a fluorescent powder obtained by mixing a small particle phosphor constituting the fluorescent film and a small particle phosphor having a smaller size than the small particle in a predetermined ratio. It is done.
