Abstract
본 발명은 음극선관용 벌브의 제조 방법에 관한 것이다. 스크린의 내면에 도전층과 광도전층을 형성한 다음, 광도전층을 대전시키는 단계, 패널 내면에 섀도우마스크를 고정하고, 광도전층을 노광한 다음, 미노광부의 전하를 중화시키는 단계 및 정전기적 인력을 이용하여, 적색, 청색 및 녹색 발광 형광체를 순차적으로 상기 광도전층 위에 부착시키는 단계를 통하여 형광막을 갖는 음극선관용 벌브의 제조 방법에 있어서, 상기 형광체를 부착시킨 다음, 휘발성 용제를 증발시켜 증발된 용제에 의해 상기 형광체를 반고착시키는 단계를 통하여 제조되는 음극선관용 벌브는 선면도와 휘도가 우수하고, 그 제조 과정에서 벌브의 구멍이 막히는 정도가 크게 줄어들어 생산성이 향상된다.The present invention relates to a method for producing a bulb for a cathode ray tube. Forming a conductive layer and a photoconductive layer on the inner surface of the screen, then charging the photoconductive layer, fixing the shadow mask on the inner surface of the panel, exposing the photoconductive layer, neutralizing the charge of the unexposed portion, and electrostatic attraction In the manufacturing method of a bulb for a cathode ray tube having a fluorescent film through the step of attaching red, blue and green light emitting phosphors sequentially on the photoconductive layer, the phosphors are attached, and then the volatile solvent is evaporated to evaporate the solvent. The cathode tube produced through the step of semi-fixing the phosphor by the bulb excellent in line and luminance, the degree of clogging of the bulb in the manufacturing process is greatly reduced, the productivity is improved.
