Abstract

본 발명은 디스플레이장치에 있어서, 파라미터 조정방법에 관한 것으로서, D-sub 콘넥터, 마이콤, 수직편향부, 수평편향부, 고압부, 프리앰프 및 영상출력부와 전원부를 구비한 디스플레이장치에 있어서, 마이콤에서 다단계의 조정폭을 설정하는 단계, 키입력부를 통해 파라미터 조정명령이 인가되었는가를 판단하는 단계, 설정된 조정폭 중에서 키입력부를 통해 인가된 파라미터 조정명령에 따라 해당 조정폭 및 해당 파라미터를 선택하는 단계와, 해당 파라미터에 대하여 해당 조정 폭으로 조정된 디지탈/아날로그 변환값을 수직편향부, 수평편향부, 프리앰프 및 영상출력부 또는 전원부로 출력하는 단계로 구성된다. 따라서, 마이콤이 다단계의 조정폭을 가지므로 사용자가 미세 조정에서부터 원하는 증감폭으로 파라미터를 조정할 수 있고, 공장에서 자동조정시에 초기에는 최대 조정폭으로 파라미터를 조정한 후 점차적으로 소폭의 조정폭으로 파라미터를 조정함으로써 자동조정에 소요되는 시간을 줄일 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for adjusting a parameter in a display device, the display device comprising a D-sub connector, a microcomputer, a vertical deflection unit, a horizontal deflection unit, a high voltage unit, a preamplifier, an image output unit, and a power supply unit. Setting a multi-stage adjustment width, determining whether a parameter adjustment command is applied through the key input unit, selecting a corresponding adjustment width and a corresponding parameter according to a parameter adjustment command applied through the key input unit from the set adjustment width, and corresponding parameters And outputting the digital / analog conversion value adjusted to the corresponding adjustment width to the vertical deflection unit, the horizontal deflection unit, the preamplifier and the image output unit, or the power supply unit. Therefore, the microcomputer has a multi-step adjustment range, so that the user can adjust the parameter from fine adjustment to the desired increase / decrease.In the case of automatic adjustment at the factory, the parameter is adjusted initially to the maximum adjustment range and then gradually adjust the parameter to the small adjustment range. This reduces the time required for automatic adjustment.
