Abstract

본 발명은 음극선관용 형광면 형성 방법에 관한 것으로서, 보다 상세하게는 음극선관의 형광면 노광 시 형광막과 메탈 백의 경계면을 고르게 함으로써 휘도를 향상시킬 수 있는 음극선관용 형광면 형성 방법에 관한 것이다.The present invention relates to a method for forming a fluorescent surface for a cathode ray tube, and more particularly, to a method for forming a fluorescent surface for a cathode ray tube that can improve luminance by leveling the interface between the fluorescent film and the metal back when exposing the cathode surface of the cathode ray tube.

발명의 목적은 메탈 백과 형광막과의 경계면이 거칠게 형성됨에 따른 음극선관의 휘도 저하를 방지할 수 있는 음극선관용 형광면 형성 방법을 제공함에 있다.An object of the present invention is to provide a method for forming a fluorescent surface for a cathode ray tube that can prevent the lowering of the brightness of the cathode ray tube due to the rough interface between the metal back and the fluorescent film.

상기한 목적을 달성하기 위해서, 판넬(P)에 형광체(51)와 블랙 매트릭스(52)를 도포하여 건조하고, 상기한 형광체(51)와 블랙 매트릭스(52)의 상부에 PVC계 고분자 합성물질(1)을 도포하며, 상기한 PVC계 고분자 합성물질(1)의 상부에 메탈 백(53)을 도포하여 건조시킨 후 벌브를 봉지하고, 상기한 PVC계 고분자 합성물질(1)을 태워 형고아막을 형성함을 특징으로 하는 음극선관용 형광막 형성 방법을 제공한다.In order to achieve the above object, the phosphor 51 and the black matrix 52 are coated and dried on the panel P, and the PVC-based polymer composite material (above the phosphor 51 and the black matrix 52) is applied. 1) is applied, the metal bag 53 is applied to the upper portion of the PVC-based polymer composite material (1), dried, encapsulated with a bulb, and burned the PVC-based polymer composite material (1) to form a mold orphan film. It provides a fluorescent film forming method for a cathode ray tube characterized in that the forming.
