Claims (3)
- CRT 디스플레이장치의 화면 기울기 조절회로에 있어서, 제 1 전원전압(VCC1)과 제 3 전압(GND)사이에 접속되어 전압분압 출력하는 가변저항(VR1)및 (VR2)돠, 상기 제 1전원전압(VCC1)과 제 3 전원전압(GND) 사이에 2개의 트랜지스터가 퓨쉬풀 접속되며, 베이스로 입력되는 상기 가변저항(VR1) 또는 (VR2)의 출력에 따라 제 1 전원전압(VCC1) 또는 제 3 전압(GND)를 출력하는 제 1, 제 2 기울기 조절회로(10)(20)와, 상기 제 1 기울기 조절회로(10)의 출력단자와 제 2 전원전압(VCC2) 사이에 직렬 접속되어 상기 제 1 기울기 조절회로(10)의 전압출력에 따라 전자력을 형성하는 수직 제 1코일(L1) 및 수직 제 2 코일(L2)과 상기 제 2 기울기 조절회로(20)의 출력단자와 상기 제 2 전원전압(VCC2)사이에 직렬 접속되어 제 2 기울기 조절회로(20)의 전압출력에 따라 전장력을 발생하는 수평 제 1 코일(L3) 및 수평 제 2 코일(L4)로 구성됨을 특징으로 하는 회로.
- 제 1 항에 있어서, 제 1, 제 2 수직코일(L1)(L2)각각이 CRT의 상측과 하측에 각각 설치되어 입력전압에 따른 전류방향에 의한 전자력을 발생하여 CRT내빔을 상측 또는 하측으로 이동시키는 것을 특징으로 하는 회로.
- 제 1 항에 있어서, 제 1, 제 2 수평코일(L3)(L4) 각각이 CRT 좌측과 우측에 각각 설치되어 입력전압에 따른 전류방향에 의한 전자력을 발생하여 CRT내 빔을 좌우 이동시키는 것을 특징으로 하는 회로.
