Abstract
Description
Claims (4)
- CRT 화면의 밝기에 따른 고압변화에 대해서 상의 부분적인 휨 발생을 보상하기 위한 회로에 있어서,상기 CRT 화면의 특정부분이 밝아 휘도차가 발생하여 애노드전압이 떨어지면 편향력을 같이 떨어뜨려 그 특정부분의 주변에 상의 부분적인 휨 발생을 보상하는 고압보상수단을 포함하는 것을 특징으로 하는 고압보상회로.
- 제 1항에 있어서, 상기 고압보상수단은고압출력전압을 적분하는 적분기;입력되는 E-W보정파형과 상기 적분기의 출력파형을 합성하는 합성기; 및상기 합성파형을 반전증폭하여 고압보상을 위한 E-W보정파형을 구하고, 이를 상기 CRT의 편향부에 공급하는 반전증폭기를 구비함을 특징으로 하는 고압보상회로.
- 제 2항에 있어서, 적분기의 상기 고압출력전압은 고압발생을 위한 플라이백트랜스에서의 전압인 것을 특징으로 하는 고압보상회로.
- 제 2항에 있어서, 합성기의 상기 E-W보정파형은 수직의 파라볼라파형을 수평출력의 전류에 인가하여 수평전류의 크기를 보정하여 상기 CRT 화면의 좌우 실감이 찌그러지는 왜곡을 보정하는 파형인 것을 특징으로 하는 고압보상회로.
