Abstract
Description
Claims (3)
- 전자빔을 방사하는 복수개의 전자 방사 수단, 상기 전자빔의 방사량을 조절 및 제어하기 위한 제어전극 및 가속전극으로 구성된 삼극부, 및 상기 전자빔을 스크린에 집속과 가속을 수행하기 위한 다수의 전극들을 포함하는 컬러 수상관용 전자총에 있어서,상기 복수개의 전자 방사 수단 및 다수의 전극들은 서로 일정간격 떨어져 관축 방향으로 순차 배치되어 있으며, 상기 삼극부를 형성하는 전극들 중 단일 판재의 제어전극 또는 가속전극에는 전자빔 통과공 주위에 가로와 세로의 폭이 다른 비대칭 슬롯이 형성되어 있으며, 적어도 슬롯 폭이 좁은 방향에서 관축에 대한 상기 슬롯의 두께방향 경사 각도가 70°이상인 것을 특징으로 하는 컬러 수상관용 전자총.
- 제 1 항에 있어서,상기 슬롯 형성 표면의 두께(즉 공 주위 두께)가 전자빔 통과공경의 0.4 ∼ 1.0배이고, 상기 슬롯이 형성된 부분의 두께가 전자빔 통과공경의 0.1 ∼ 0.2배 인 것을 특징으로 하는 컬러 수상관용 전자총.
- 제 1 항에 있어서,제어전극의 전자빔 통과공은 수평으로 크고 수직으로 작은 횡장형인 것을 특징으로 하는 컬러수상관용 전자총.
