Abstract

본 발명은 칼라 음극선관의 컨버젼스 측정방법 및 장치에 관하여 개시한 것이다. 본 발명에 의한 칼라 음극선관의 컨버젼스 측정방법 및 장치는 컨버젼스 측정대상 음극선관 세트의 화면 앞에 화상 패턴 감지용 광센서를 구비하고, 음극선관 빔의 움직임을 통해 광센서가 화상패턴에 대한 정보를 감지하여 신호변환한 후, 이 신호를 통해 R,G,B빔의 미스컨버젼스량을 측량하여 디스플레이시킴으로써, 음극선관 컨버젼스의 측정 및 조정을 보다 정밀하고 용이하게 행할 수 있을 뿐만 아니라 작업시간 단축 및 작업능률 향상을 기할 수 있는 효과를 얻을 수 있도록 한 것이다.The present invention discloses a method and apparatus for measuring convergence of colored cathode ray tubes. The method and apparatus for measuring convergence of a color cathode ray tube according to the present invention include an optical sensor for detecting an image pattern in front of a screen of a cathode ray tube set for convergence measurement, and an optical sensor detects information on an image pattern through a movement of a cathode ray tube beam. After converting the signal, it is possible to measure and adjust the cathode ray tube convergence more accurately and easily by measuring and displaying the amount of misconvergence of R, G, and B beams through this signal. The effect is to achieve an improvement.
