Abstract

광원에 근접한 개구부어레이, 광출력면 면적보다 적은 광입력면 면적을 갖는 테이퍼 광학요소 어레이를 포함하는 개선된 배면광 어셈블리가 제공된다.
광선은 개수부를 지나 부분적으로 시준된 광원을 제공하기 위하여 내부 반사를 통해 광선을 투과시키는 광학요소로 향한다.
그 후 광선은 굴절을 통해 광선을 투과시키는 마이크로렌즈 어레이를 통과하고 디스플레이요소를 위한 본질적으로 보다 시준된 광원을 제공한다.
본 발명의 배면광 어셈블리는 전기-광학적 디스플레이, 특히 군사용 및 항공용으로 적용하도록 설계된 배면광수단(backlighting means)으로서 이익적으로 사용된다.
