Abstract

3개의 전자빔을 하나의 수평면으로 방사하는 인라인형 전자총에 관한 것으로써, 편향수차에 의한 전자빔스폿직경의 왜곡을 저감함고 동시에 화면중앙 뿐만 아니라 화면주변에서도 최적한 포커스를 얻을 수 있어 화면전역에서 높은 해상도를 얻을 수 있게 하기 위해, 주렌주부에서 본 3극부의 수평방향의 물점이 수직방향의 물점보다 먼 위치로 되도록 또 이 3극부에 있어서의 수직방향의 이미턴스가 수평방향의 이미턴스보다 적게 되도록 제1리그드(2)의 전자빔 통과구멍(2c)(2d)의 형상을 혀성함과 동시에 주렌즈부의 수평방향의 포커스전압보다는 수직방향의 포커스전압이 150~300V 높게 되도록 주렌즈를 형성하는 전극(4)의 전자빔 통과구멍(4b)(4c)및 차양전극(4d)의 형상 및 크기를 형성하였다.It is an inline type electron gun that emits three electron beams in one horizontal plane, and reduces distortion of the electron beam spot diameter due to deflection aberration, and at the same time obtains the optimum focus not only in the center of the screen but also around the screen. In order to be able to obtain, the horizontal point of the three-pole part seen from the main part of the main part is located farther from the vertical point and the vertical-emittance in this three-pole part is smaller than the horizontal one. An electrode which forms the main lens so that the shape of the electron beam through holes 2c and 2d of the one-lead 2 is formed and the focus voltage in the vertical direction is 150 to 300 V higher than the horizontal focus voltage in the main lens portion ( The shapes and sizes of the electron beam passing holes 4b and 4c and the shade electrode 4d of 4) were formed.

이러한 전자총을 이용하는 것에 의해, 바늘꽂이 자계에 의한 수직방향의 접속방향을 저감시켜 받기 어렵게 하는 것만이 아니라 화면전역에서 최적한 포커스를 실현할 수 있어 코해상도를 실현할 수 있다.By using such an electron gun, not only does it make it difficult to reduce the connection direction in the vertical direction by the needle holder magnetic field, but also the optimum focus can be realized throughout the screen, and the co-resolution can be realized.
