Abstract

In the TFT-LCD(Thin Film Transistor-Liquid Crystal Display) panel manufacturing industry, SAMSUNG, a late entry, can catch up to leading first mover, SHARP. The changes the note, monitor, TV, and mobile markets in the TFT-LCD industry were studied using a system analysis method. In addition, the fast response time technology in SAMSUNG TFT-LCD technology was developed using the TRIZ method. For example, a new liquid crystal mixture of a wide view angle and fast response time were developed by doping a new high birefringence liquid crystal material in a base mixture using the contradiction method and su-field method of TRIZ. The response time of a new liquid crystal mixture was improved to approximately 60%(16.2ms with base LC mixture, 9.8ms with a new LC mixture).

TFT-LCD 패널 제조 산업에서 삼성전자는 후발기업으로써 선발기업인 일본의 샤프를 추월하여 선도하고 있다. 트리즈 시스템 분석을 활용하여 디스플레이 산업은 노트, 모니터, TV & 모바일 제품 시장으로 변화를 하였으며 시장(고객)의 요구속성도 변화를 함을 제시하였다. 또한 삼성의 TFT-LCD 기술 중 빠른 응답 기술 혁신 사례를 제시하였다. 예를 들면, 응답속도 개선을 위해 기존 사용하고 있는 액정 혼합물에 트리즈의 모순성, 물질-장 방법 등을 활용하여 개발된 고복굴절률 액정물질을 첨가하여 광시야 각, 빠른응답 특성을 갖는 신규 액정 혼합물을 개발하였다. 새로운 액정혼합물의 응답속도는 60%정도로 단축 개선되었다(기존 액정 사용 시 16 ms, 새로운 액정혼합물 사용 시 10ms).
