Abstract

본 발명은 칼라 수상관의 형광막 스크린을 형성함에 있어서, 3색 형광체의 입자 크기를 달리 형성시킴으로서 색순도 저하를 방지함과 함께 휘도를 향상시키는 것에 관한 것으로, 칼라 수상관에서 3색 형광체를 이용하여 형광막을 형성시키는 스크린 형성 방법에 있어서, 판넬에 도포되는 형광체 입자 크기가 먼저 도포되는 형광체가 가장 작고 가장 나중에 도포되는 형광체가 가장 크도록 하여 도포시킴을 특징으로 하는 칼라 수상관의 스크린 형성 방법에 관한 기술이다.The present invention relates to preventing the color purity from being lowered by forming different particle sizes of the three-color phosphor in forming the fluorescent film screen of the color receiver, and using the three-color phosphor in the color receiver. A screen forming method for forming a fluorescent film, wherein the phosphor particle size applied to a panel is applied so that the first applied phosphor is the smallest and the last applied phosphor is the largest. Technology.
