Claims (5)

  1. 다수의 전자 비임을 발생하여 스크린으로 향하는 경로를 따라 조사하는 전자총을 가지며, 상기 전자총이 비임 형성 영역을 구비하는 전극과 적어도 하나의 접속 렌즈를 형성하는 전극을 포함한 음극선관과 자계 필드 편향 요크를 포함한 칼라 디스플레이 시스템에 있어서, 전자 비임 전류가 사전 설정된 레벨 이하로 강하할 경우 상기 집속 렌즈를 형성하는 전극(40,42,44,46)중 하나에 동적 신호를 인가하는 수단(120)을 포함하고, 상기 동적 신호는 전자 비임을 편향시키지 않을 때 최대 전압으로 되며 전자 비임을 최대로 수평 편향시킬 때 최소로 감소되는 것을 특징으로 하는 칼라 디스플레이 시스템.
  2. 제1항에 있어서, 상기 전자 비임의 수가 3개이며, 상기 집속렌즈를 형성하는 전극이 정초점 렌즈를 형성하는 전극과 주초점 렌즈를 형성하는 전극을 구비하고, 상기 동적 신호는 상기 정초점 렌즈를 형성하는 전극(40,42,44)중 하나에 인가되는 것을 특징으로 하는 칼라 디스플레이 시스템.
  3. 제2항에 있어서, 상기 전자총이 3개의 캐소드로부터 길이방향으로 간격진 6개의 전극을 포함하며, 상기 동 적신호는 상기 캐소드(34)로부터 제4전극(42)에 인가되는 것을 특징으로 하는 칼라 디스플레이 시스템.
  4. 제2항에 있어서, 상기 최대 전압값은 상기 제1전압값과 동일한 것을 특징으로 하는 칼라디스플레이 시스템.
  5. 제2항에 있어서, 전자비임 전류의 상기 사전 설정된 값은 약 200 마이크로 암페아 피크인 것을 특징으로 하는 칼라 디스플레이 시스템.
