Abstract
이 발명은 고화질 텔레비젼에 사용되는 투사형 브라운관의 페이스 판넬의 구조에 관한 것으로서, 페이스판넬의 내면 주변부(12),(12')가 구면으로 형성되어 형광막(11)에 충돌된 빔에 의하여 발산된 빛이 집중되고, 중심부(13)이 플레트하게 형성되어 편향 궤적과의 오차가 줄어 포커싱 및 휘도가 상승되는 효과가 있다.The present invention relates to a structure of a face panel of a projection type CRT tube used for high-definition television, wherein the inner peripheral portions 12 and 12 'of the face panel are spherically formed and emitted by a beam impinging on the fluorescent film 11. Light is concentrated, and the center portion 13 is formed in a flat manner, thereby reducing an error with a deflection trajectory, thereby increasing focusing and brightness.
