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.

LCD Backlight에서 Micro Fresnel Lens Array (MFLA)가 결합된 도광판을 설계${\cdot}$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.
