Abstract
본 발명은 칼라음극선관의 제조방법 및 이에 의한 음극선관에 관한 것이다.The present invention relates to a method for producing a color cathode ray tube and a cathode ray tube thereby.
본 발명은 통상의 방법에 의해 코팅-대전-노광-현상단계를 거친 이후에, 광전도막의 폴리머바인더 성분을 용해시키는 유기용매를 광전도막에 분사시켜, 형광체 입자가 용해된 광전도막의 폴리머바인더 속으로 박혀 들어가고, 용해된 광전도막의 폴리머바인더 성분이 상기 형광체입자의 위로 스며나와 얇은 막을 형성시키는 고착단계를 포함하는 것을 특징으로 하는 칼라음극선관의 건식전자사진식 스크린 제조방법을 제공한다.After the coating-charging-exposure-developing step is carried out by a conventional method, an organic solvent for dissolving the polymer binder component of the photoconductor film is sprayed onto the photoconductor film, so that phosphor particles are dissolved in the polymer binder of the photoconductor film. It provides a method for producing a dry electrophotographic screen of a color cathode ray tube, characterized in that it comprises a fixing step of being embedded into the polymer binder component of the dissolved photoconductive film soaks up the phosphor particles to form a thin film.
본 발명은 고착공정에서 가열융착이 아닌 폴리머의 용해를 이용하므로 종래와는 달리 에너지의 소모가 적고, 또한 고착공정에서 각각의 형광체 입자를 광전도막 속에 견고하게 고착시킴과 동시에 그 형광체 입자의 표면 위에 얇고 평활한 피막을 형성하므로 그 이후 별도의 라커막 공정을 생략할 수 있게 된다.The present invention utilizes dissolution of the polymer rather than heat fusion in the fixing process, which requires less energy than in the prior art, and also firmly fixes each phosphor particle in the photoconductor film in the fixing process and simultaneously on the surface of the phosphor particle. Since a thin and smooth film is formed, a separate lacquer film process can be omitted after that.
