Abstract

본 발명은 수직사이즈의 보정의 가능한 고압 및 수직사이즈 조정회로부에 관한 것이다.The present invention relates to a high voltage and vertical sizing circuitry capable of vertical size correction.

수직사이즈 조정회로(32)에 접속되어 수직사이즈 조정회로(32)에 입력되는 전압을 조정하는 전압조정회로(31)와, 상기 전압조정회로(31) 및 수직사이즈 조정회로(32)에 접속되어 수직사이즈 조정회로(32)에 입력되는 전압을 수정하는 수직사이즈 보정회로(33)로 구성된다.A voltage regulating circuit 31 connected to the vertical resizing circuit 32 for regulating a voltage input to the vertical resizing circuit 32 and a voltage regulating circuit 31 connected to the voltage regulating circuit 31 and the vertical size regulating circuit 32 And a vertical size correcting circuit 33 for correcting the voltage inputted to the vertical size adjusting circuit 32. [

이렇게 함으로써, CRT에 입력되는 전압이 일정이상 크게 되는 것을 탐지하여 수직사이즈를 조정할 수 있다.By doing so, it is possible to detect that the voltage input to the CRT becomes larger than a certain level, and adjust the vertical size.
