Title
(KO) 내장된 불순물을 가지는 도광판 및 그의 제조 방법
Abstract
(KO)
본 발명은 가장자리에 조명되고 가장자리에 대해 수직으로 위치하는 두 표면 중 적어도 하나에 의해 가장자리에 공급되는 빛을 재방출하는 LCD 모니터 뿐만 아니라 안내 간판 및 광고 간판의 역광 조명에 적당한 도광판에 관한 것이다. 가장자리에 공급되는 광원의 빛이 전반사를 극복함으로써 표면 중 하나에 의해 다시 도광판을 떠날 수 있도록 하기 위해서는, 도광판에서 광선들이 계획적으로 편향되어야 한다. 도광판의 두 표면 중 하나에서 도광판에 광학 불순물 (2)이 제공되고, 이것은 필름 (5)에 의해 손상으로부터 보호된다. 게다가, 간단한 상기 불순물 적용 방법이 제공된다.
