Claims (1)

프라이백 트랜스포머 및 수직방향 코일을 구비한 포커스 보정회로에 있어서, 상기 플라이백 트랜스포머 2차측의 수평편향 코일의 한단으로 부터 귀선 펄스를 트리거하여 공진시키는 LC공지회로와, 상기 플라이백 트랜스포머 2차측의 타단으로부터 직류 펄스를 정류하는 DC정류부와, 상기 수직편향 코일로 부터 출력된 파라볼라형 파형을 소정증폭하여 수직 포커스 전압을 발생하는 수직 다이나믹 포커스 증폭부와, 상기 LC공진회로 출력과 상기 수직 다이나믹 포커스 증폭부 출력을 중첩한후 상기 DC정류 출력에 재 중첩하여 보정된 포커스 전압을 출력하는 신호가 결합부로 구성됨을 특징으로 하는 회로.A focus correction circuit having a flyback transformer and a vertical coil, comprising: an LC known circuit for resonating by triggering a retrace pulse from one end of a horizontal deflection coil on the flyback transformer secondary side, and the other end of the flyback transformer secondary side; A DC rectifier for rectifying the DC pulse from the capacitor; a vertical dynamic focus amplifier configured to generate a vertical focus voltage by amplifying the parabola waveform output from the vertical deflection coil; and the LC resonance circuit output and the vertical dynamic focus amplifier. And a signal for outputting a corrected focus voltage by superimposing the output and superimposing the DC rectified output again. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
