Abstract

본 발명은 TFT-LCD 모듈의 메인 클록을 발생하는 발진부와, 상기 메인 클록을 상기 TFT-LCD 모듈의 색신호 주파수에 적절한 주파수로 분주하여 색신호 주파수 클록과 구동신호로 각각 출력하는 클록 분주부와, 상기 TFT-LCD 모듈의 색신호 입력단자 중 적어도 하나 이상을 선택하여 상기 색신호 주파수 클록을 전송하는 색 선택 스위치부로 구성된 TFT-LCD 모듈용 패턴 발생장치에 관한 것으로서, 저가의 부품으로 구성되어 제작 비용을 10만원대로 줄일 수 있기 때문에 수백개의 TFT-LCD 모듈의 화면에 패턴을 동시에 디스플레이해야 하는 경우 설치 비용을 대폭 줄일 수 있고, 한개의 TFT-LCD 모듈에 하나씩 전용으로 연결되어 각 TFT-LCD 모듈의 화면에 각기 다른 특정 컬러패턴을 디스플레이시킬 수 있기 때문에 화질 검사시 검사원이 각 TFT-LCD 모듈의 화면에 원하는 패턴을 디스플레이시켜 상기 TFT-LCD 모듈을 검사할 수 있는 잇점이 있다.The present invention provides an oscillation unit for generating a main clock of a TFT-LCD module, a clock divider for dividing the main clock at a frequency appropriate for the color signal frequency of the TFT-LCD module, and outputting them as a color signal frequency clock and a driving signal, respectively; The present invention relates to a pattern generator for a TFT-LCD module, comprising a color selection switch unit for selecting at least one or more of the color signal input terminals of the TFT-LCD module to transmit the color signal frequency clock. If you need to display patterns on the screen of hundreds of TFT-LCD modules at the same time, the installation cost can be greatly reduced, and one TFT-LCD module can be connected to one TFT-LCD module. Since it is possible to display different specific color patterns, the inspector can select the desired pattern on the screen of each TFT-LCD module. By displaying has the advantage that can be tested for the TFT-LCD module.
