Abstract

본 발명은 형광 표시관을 개시한다.The present invention discloses a fluorescent display tube.

본 발명에 따른 형광 표시관은, 그 내면에 배선층과 절연층 그리고 도전층과 형광체층이 순차 형성된 기판과, 상기 기판상면에 설치되며 열전자를 제어하는 그리드와, 상기 기판상면에 설치되며 열전자를 방출하는 음극 필라멘트를 지지하는 음극지지 장치를 구비하는 형광 표시관에 있어서, 상기 음극지지 장치가, 상기 기판상면에 프릿트 글래스에 의해 고착되며 어느 일측의 단변부와 인접된 부위와 그 전면에 소정길이 절개된 절개홈 또는 이 절개홈에 대응되는 걸림턱이 다수 마련된 마운트와, 음극 필라멘트를 지지하며 상기 마운트의 절개홈 또는 걸림턱과 대응되는 부위에 상기 절개홈 또는 걸림턱과 끼워결합되는 걸림턱 또는 절개홈이 마련된 서포터를 구비하여 된 것으로서, 마운트에 서포터를 고정함에 있어 그 용접부위가 적어 용접산포가 거의 발생되지 않는다. 이에 의해서는 서포터에 지지된 음극 필라멘트가 정확히 형광체층 상면에 위치되어 균일한 휘도의 화상을 얻을 수 있는 유용한 발명이다.The fluorescent display tube according to the present invention includes a substrate having a wiring layer, an insulating layer, a conductive layer, and a phosphor layer sequentially formed on the inner surface thereof, a grid installed on the substrate and controlling hot electrons, and emitting hot electrons on the substrate. In a fluorescent display tube comprising a cathode support device for supporting a cathode filament, the cathode support device is fixed to the upper surface of the substrate by frit glass, adjacent to the short side portion of any one side and a predetermined length on the front surface thereof. A mount having a plurality of cutout grooves or cutouts corresponding to the cutout grooves, a catching jaw that is coupled to the cutout or catching jaw at a portion supporting the cathode filament and corresponding to the cutout or catching jaw of the mount or It is provided with a supporter provided with a cutout groove, and the welding part is small in fixing the supporter to the mount. It rarely occurs. This is a useful invention in which the cathode filament supported by the supporter is accurately positioned on the upper surface of the phosphor layer to obtain an image of uniform brightness.
