Abstract
Description
Claims (4)
- 백색광을 방사하는 광원과, 상기 광원으로부터 방사된 빛을 일정방향으로 반사시키는 반사수단과, 상기 반사수단에서 반사된 빛을 다수개의 광섬유를 통해 목적하는 곳으로 전송하는 광전송수단과, 상기 광전송수단으로부터 전송되어 온 빛을 화상으로 변환하는 액정판넬과, 상기 액정판넬에서 출력된 화상을 확대시키는 투사렌즈로 구성된 두부탑재형 광학표시장치에 있어서, 상기 광전송수단은 광원의 빛을 집속하는 집속부와, 상기 집속부에서 집속된 빛을 전송하는 전송부와, 상기 전송부에 의해 전송된 빛을 임의의 크기로 변형시키는 변형부로 구성되고 상기 변형부의 단면은 액정판넬과 일정한 각도로 기울어져 있는 것을 특징으로 하는 두부탑재형 광학표시장치.
- 제1항에 있어서, 상기 집속부와 변형부는 중심으로부터 가장자리로 갈수록 굴절율 분포가 서서히 감소하는 것을 특징으로 하는 두부탑재형 광학표시장치.
- 제1항에 있어서, 상기 집속부, 전송부, 변형부는 서로 마주보는 단면의 중심이 일치하도록 구성한 것을 특징으로 하는 두부탑재형 광학표시장치.
- 제1항에 있어서, 상기 전송수단과 액정판넬 사이에는 전송된 빛의 경로를 바꾸어주는 마이크로렌즈를 더 포함하여 구성한 것을 특징으로 하는 두부탑재형 광학표시장치.
