  • Method and apparatus for adjusting a screen gradient in a video display device
    Patent number: 5986696
    Abstract: A method and a gradient adjusting apparatus for automatically testing and correcting the gradients of a screen of a video display device such as a cathode ray tube (CRT) and a front case in a production assembly line before assembling the CRT and the front case, thereby reducing unnecessary operations and minimizing inferiority of the video display device. In addition, death from shock caused by a high voltage is prevented by automatically supplying the high voltage, a deflection voltage and a gradient test pattern to a CRT assembly which is transported through a conveyer belt.
