Description
Claims (4)
- CRT의 외측 전면에 구비되는 두 장의 절연필름과,상기 두장의 절연필름 사이에 부착되어 상기 CRT로부터 방사되는 전자파를 검출하는 제1도전체와,상기 두장의 절연필름 사이에 부착되어 상기 CRT로부터 방사되는 전자파를 제거하기 위한 전자파 제거용 신호를 출력하는 제2도전체와,상기 제1도전체가 검출한 전자파를 반전 증폭하여 전자파 제거용 신호를 생성하고, 그 생성된 전자파 제거용 신호를 상기 제2도전체로 출력하여 방사하는 전자파 제거회로를 포함하는 것을 특징으로 하는 영상 표시기기의 전자파 차단용 안테나.
- 제1항에 있어서, 상기 절연 필름 중 어느 하나는 상기 도전체 중 하나가 상기 전자파 제거회로와 접속되는 도선의 커넥터와 용이하게 결합될 수 있도록 외부로 돌출된 도선 결합부를 형성하고, 이 도선 결합부에 상응하여 상기 도전체의 일부도 돌출 형성되는 것을 특징으로 하는 영상 표시기기의 전자파 차단용 안테나.
- 제1항에 있어서,상기 제1도전체는 상기 CRT의 전면을 넓게 커버할 수 있도록 절연필름의 외부 표면을 따라 거의 "디귿자(ㄷ 자)" 형태를 취하며,상기 제2도전체는 상기 제1도전체보다 크기가 작고 직선 형태를 취함을 특징으로 하는 영상표시기기의 전자파 차단용 안테나.
- CRT의 전면에 부착하기 위한 두장의 절연필름 중 어느 하나의 외부 표면을 따라 두 개의 도전체를 부착하는 단계와,상기 절연필름위에 부착된 두개의 도전체위에 다른 절연필름을 부착시키는 단계와,상기 두개의 절연필름내의 두개의 도전체와 연결되어 있는 도선 결합부들과 상기 두개의 도전체중 어느 하나가 검출하는 전자파를 증폭 반전하여 다른 도전체로 제공하는 전자파 제거회로를 접속시키는 단계로 구성됨을 특징으로 하는 영상표시기기의 전자파 차단용 안테나 제조 방법.
