Abstract

본 발명은 음극선관의 스크린 제조용 방전장치에 관한 것으로서, 음극선관의 패널 내면의 곡률과 동일한 곡률로 가동된 부도체 재질로 된 테프론이 구비되고, 테프론 상면에는 현상용기내로 분사시 균일한 방전특성을 분포하여 패널 내면에 형광체분말을 부착시키는 방전수단을 고정시킴으로써, 방전장치의 전극 제작시 작업성 및 가공성을 향상시킴은 물론 화학 부식방법에 의해 경비를 줄이고, 특히 패널 내면의 광전도막을 보다 균일하게 대전시킬 수 있다.The present invention relates to a discharge device for screen production of cathode ray tubes, comprising a teflon made of a non-conductor material that is operated at the same curvature as the curvature of the inner surface of the cathode ray tube, and the top surface of the teflon distributes uniform discharge characteristics when sprayed into the developing container. By fixing the discharge means for attaching the phosphor powder on the inner surface of the panel, not only improves workability and workability when manufacturing the electrode of the discharge device, but also reduces the cost by chemical corrosion method, and in particular, more uniformly charges the photoconductive film on the inner surface of the panel. You can.
