Abstract
수평편향 신호가 입력되면, 상기 수평편향 신호와 동일한 주파수를 갖는 수평 페레볼라 신호를 생생하여 출력하는 수평 패러볼라 신호 발생부(30)와; 수평 페러볼라 신호 발생부로부터 입력되는 수평 페러볼라 신호와, 수평 귀선 소거신호를 서로 중첩하여 출력하는 수평측 신호 합성부(40)와; 수직편향 신호가 입력되면, 상기 수지편향 신호와 동일한 주파수를 갖는 수직 패러볼라 신호를 생생하여 출력하는 수직 패러볼라 신호 발생부(50)와; 수직 패러볼라 신호 발생부로부터 입력되는 수직 패러볼라 신호와, 수직 귀선 소거신호를 서로 중첩하여 출력하는 수직측 신호 합성부(60)와; 수평측 신호 합성부 및 상기 수직측 신호 합성부로부터 입력도는 신호를 반전시킴과 동시에 서로 합성하여 출력하는 제어 그리드 전압 공급부910)로 구성되어; 전자빔이 회면의 주변부를 주사하는 경우에 제어 그리드 전극에 공급되는 전압을 2차 함수적으로 증가시킴으로써 화면 주변부의 휘도가 화면 중앙부의 휘도와 같아지도록 하여 휘도의 균등도를 높인 음극선관의 휘도 균등도 자동 보정장치에 관한 것.A horizontal parabolic signal generator 30 for generating and outputting a horizontal peregolar signal having the same frequency as the horizontal deflection signal when the horizontal deflection signal is input; A horizontal side signal synthesizing unit 40 for superposing and outputting the horizontal parabola signal inputted from the horizontal parabolic signal generating unit and the horizontal blanking cancellation signal; A vertical parabola signal generator 50 which vibrates and outputs a vertical parabola signal having the same frequency as the resin deflection signal when a vertical deflection signal is input; A vertical side signal synthesizing unit 60 for outputting a superimposed vertical parabola signal inputted from the vertical parabola signal generating unit and a vertical blanking signal; An input diagram from a horizontal signal synthesizing unit and a vertical signal synthesizing unit inverts signals and simultaneously synthesizes and outputs a control grid voltage supply unit 910; In the case where the electron beam scans the peripheral part of the screen, the voltage supplied to the control grid electrode is increased by a quadratic function so that the luminance of the cathode ray tube with the luminance uniformity is increased by making the luminance of the screen periphery equal to the luminance of the center of the screen. Of automatic compensators.
