Abstract
본 발명은 형광 표시 장치에 관한 것으로서, 형광 표시 장치는 소정 간격을 유지하는 전면판 및 배면판 그리고 이들 사이에 개재되어 하나의 차폐된 내부공간을 구획 형성하는 측면판, 상기 전면판의 내면에 순차 형성되는 애노드 및 형광층, 상기 배면판의 내면에 형성되는 후방전극, 상기 후방전극과 상기 형광층의 사이의 소정위치에 위치되는 가속전극 및 제어 그리드군, 상기 후방전극과 상기 가속전극의 사이에 위치되는 캐소우드를 구비하며, 상기 가속전극과 제어 그리드 사이 및/또는 상기 후방전극과 상기 캐소오드의 사이에 화면 주변 전위 강화를 위한 하나 또는 그 이상의 보조 전극이 설치되어 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent display device, wherein the fluorescent display device includes a front plate and a rear plate which maintain a predetermined distance, and a side plate interposed therebetween to form one shielded inner space, and sequentially on an inner surface of the front plate. An anode and a fluorescent layer formed, a rear electrode formed on an inner surface of the back plate, an acceleration electrode and a control grid group positioned at a predetermined position between the rear electrode and the fluorescent layer, between the rear electrode and the acceleration electrode A cathode is located, and one or more auxiliary electrodes are provided between the acceleration electrode and the control grid and / or between the rear electrode and the cathode to enhance the potential around the screen.
이러한 구조적 특성을 가진 본 발명의 형광 표시 장치는 보조전극에 의한 전자렌즈의 방향 수정을 통해 중심부와 가장자리부의 휘도차를 개선하여 종래보다 월등히 향상된 해상도를 얻을 수 있어 제품의 경쟁력을 더 한층 높이게 될 것이다.The fluorescent display device of the present invention having such a structural characteristic can improve the product competitiveness by improving the luminance difference between the center and the edge portion by correcting the direction of the electron lens by the auxiliary electrode, thereby improving the product's competitiveness. .
