Abstract

Nowadays, the pattern size of BLU (Back Light Unit) adopted in TFT-LCD (Thin Film Transistor Liquid Crystal Display) is typically a few tens of micrometers. However, recently, researches on the TFT-LCD output characteristics depending on various types of BLU patterns are being performed in order to improve the output and uniformity. In this study, we analyzed the influence of pattern size, distribution, and areal ratio on the output characteristics.

현재 TFT-LCD(Thin Film Transistor Liquid Crystal Display)에 사용되는 BLU(Back Light Unit) 패턴 크기는 수 십 ${\mu}m$인데 반해, 최근에는 BLU 패턴의 크기를 수 ${\mu}m$ 또는 그 이하로 조절함으로써 출력광의 휘도를 증가시키고 균일도를 향상시키고자 하는 연구가 진행되고 있다. 본 연구에서는 패턴의 크기, 분포 및 점유 면적이 출력광의 분포에 미치는 영향을 조사하였다.
