초록

LCD Backlight에서 Micro Fresnel Lens Array (MFLA)가 결합된 도광판을 설계‧분석하였다. MFLA가 적용된 도광판과 기존의 프리즘 형태의 도광판의 광학적 특성을 전산모의하여 비교한 결과를 나타내었다. MFLA를 이용한 도광판을 사용할 경우 기존의 LCD backlight 장치에서 필요로 했던 프리즘 필름을 대체할 수 있음을 보였다.

Abstract

A light-guide plate of an LCD backlight coupled with a microfresnel lens array (MFLA) is designed and analyzed. Computer simulated results of optical characteristics of our MFLA-type light-guided plate compared with the conventional prism-type one are presented. We show that the MFLA-type light-guide plate can replace well the conventional prism-type plate.
