    • 개시된 기하학적 왜곡 보정회로는 음극선관 디스플레이장치의 특성 및 제조편차에 따라 발생하는 기하학적 왜곡을 마이크로 컴퓨터를 이용하여 디지털적으로 보정함으로써 핀쿠션 일그러짐 및 사다리꼴 일그러짐 뿐만 아니라 핀쿠션 일그러짐 에 실리는 2차적 화면왜곡 현상도 방지할 수 있는 것에 관한 것이다.
      본 발명에 따른 음극선관 디스플레이장치의 기하학적 왜곡 보정회로는 음극선관 디스플레이장치의 수직 사이즈와 수직 주파수에 대하여 보상된 화면 핀쿠션 값과 2차적 화면왜곡의 값에 대하여는 2차원 파라볼라(Parabola) 데이터를 계산하여 출력하고, 보상된 화면 사다리꼴 일그러짐의 값은 구형파 형태의 펄스로 출력하며, 화면의 수직주사기간과 동기된 또다른 구형파를 출력하는 마이크로 컴퓨터와, 마이크로 컴퓨터에서 계산된 파라볼라 데이터를 수직 동기신호의 주기에 대해 각 구간별로 수평 동기신호를 클럭신호로 하여 파라볼라 파형을 발생시키는 다이나믹 DAC와, 다이나믹 DAC의 출력신호와 사다리꼴 일그러짐의 값에 대한 보상신호의 직류값을 합하여 적분함으로써 아날로그 파형으로 만들어 음극선관 디스플레이장치의 수평편향회로로 공� �하는 적분회로부로 구성됨을 특징으로 한다.
      따라서, 본 발명의 회로는 음극선관 디스플레이장치의 수직사이즈나 수직주파수가 변하더라도 왜곡없이 늘 안정된 화면을 구현할 수 있다는 장점이 있다.
