Abstract

본 고안은 박막 액정 디스플레이 모듈(TFT-LCD Module, 이하 LCD로 표기함) 조립라인에서 TAB(티에이비)가 조립된 LCD에 전원 및 일정영상을 인가하여 LCD의 TAB조립상태 즉, LCD의 성능을 검사하는 LCD 성능 검사장치에 관한 것으로서, 특히 LCD 성능검사를 위해 LCD의 전압 및 전류를 측정하는 계측수단으로 PC(Personal Computer)에 내장되는 여러 인터 페이스 장비를 사용하여 AV(에이브이)용으로 제작된 LCD와 OA(오에이)용으로 제작된 LCD를 모두 검사할 수 있도록 엘씨디 성능 검사장치에 관한 것이다.The present invention applies the power and constant image to the LCD assembled with TAB in the thin film liquid crystal display module (TFT-LCD Module, hereinafter referred to as LCD) assembly line. The present invention relates to an LCD performance inspection device for inspecting. Especially, it is a measurement means for measuring the voltage and current of LCD for LCD performance test. The present invention relates to an LCD performance tester for inspecting both LCDs and LCDs manufactured for OA.

그러나, 종래의 LCD검사장치는 AV용으로 제작되는 LCD(1)와 OA용으로 제작되는 LCD(20)를 검사하기 위한 검사장치가 각기 다르게 구성되고, 각 검사기에는 고가의 계측기가 내장되어 있기 때문에 사용자의 투자 부담이 증가하게되며, LCD의 양호 또는 불량을 판정하기 위해 작업자가 일일이 계측기에 출력되는 데이타를 판독하여 판정해야하기 때문에 작업의 능률이 저하되는 문제점이 있다.However, in the conventional LCD inspection apparatus, the inspection apparatus for inspecting the LCD 1 produced for the AV and the LCD 20 produced for the OA is configured differently, and each inspector has an expensive measuring instrument therein. The user's investment burden increases, and there is a problem in that work efficiency is reduced because an operator must read and judge data output to the measuring instrument in order to determine whether the LCD is good or bad.

따라서, 상기 문제점을 해결하기 위한 본 발명은 LCD 성능검사를 위해 LCD의 전압 및 전류를 측정하는 계측수단으로 PC에 내장되는 여러 인터페이스 장비를 사용하여 AV용으로 제작된 LCD와 OA용으로 제작된 LCD를 모두 검사할 수 있도록 하여 저렴한 가격으로 시스템을 구성할 수 있고, PC를 사용하여 시스템을 제어하기 때문에 폭넓은 LCD 성능검사가 가능하며 상위 주 시스템과의 인터페이스가 가능한 효과가 있는 LCD 성능 검사장치이다.Accordingly, the present invention for solving the above problems is the LCD produced for the AV and the LCD manufactured for the AV using a variety of interface equipment built into the PC as a measuring means for measuring the voltage and current of the LCD for LCD performance test It is possible to configure the system at a low price by inspecting all of them, and it is possible to configure the system using a PC, so it is possible to test the wide range of LCD performance and to interface with the upper main system. .
