Abstract
본 발명은 인라인형 전자총의 주렌즈직경을 크게하는 것이 가능한 컬러음극선관을 제공하는 것을 목적으로 한다. 따라서, 서로 간격을 두고 배치된 2개의 원통 형상전극으로 이루어진 주렌즈를 포함하는 인라인형 전자총을 구비한 본원의 컬러 음극선관에 있어서는, 상기 각 전극은 타원형의 개구단면을 지니는 동시에 서로 상이한 전위로 유지되고, 내부에 빔통과 구멍을 지닌 평판전극을 구비하고 있으며, 인접하는 전자빔간의 빔거리를 S, 상기 2개의 원통형상 전극의 대향단부의 개구 단면의 수직방향 직경을 D라 할때, 5.0S, DS,그리고 55S-20D147의 부동식을 만족하는 것을 특징으로 한다.An object of the present invention is to provide a color cathode ray tube capable of increasing the main lens diameter of an inline electron gun. Therefore, in the color cathode ray tube of the present application having an inline electron gun including a main lens composed of two cylindrical electrodes spaced apart from each other, each electrode has an elliptical opening cross section and is kept at different potentials from each other. And a flat electrode having a beam passage and a hole therein, wherein the beam distance between adjacent electron beams is S and the vertical diameter of the opening cross section of the opposite ends of the two cylindrical electrodes is 5.0S, DS, and meets the floating type of 55S-20D147.
