Abstract

본 발명은 잭정 프로젝터에 관한 것이다.The present invention relates to a jack well projector.

본 발명에 따른 액정 프로젝터에 따르면, 액정패널에 형성되는 화상을 투사렌즈를 통해 대형 스크린에 투사함으로써 대형화면을 관람할 수 있을 뿐만 아니라, 상술한 스크린 및 투사렌즈 이외의 스크린과 투사렌즈 본체에 별도로 마련하지 않더라도 액정패널에 형성되는 화상을 직접 관람할 수 있도록 되어 있다. 따라서, 소형화면 및 본체의 외측에 별도로 마련된 대형스크린을 통한 대형화면을 선택적으로 감상할 수있도록 하기 위한 구조가 간단할 뿐만 아니라, 밝은 주위 환경에서도 선명한 소형화면이 구현될 수 있게 된다.According to the liquid crystal projector according to the present invention, not only the large screen can be viewed by projecting an image formed on the liquid crystal panel onto the large screen through the projection lens, but also provided separately on the screen and the projection lens body other than the screen and the projection lens described above. If not, the image formed on the liquid crystal panel can be directly viewed. Therefore, not only the structure for selectively viewing the large screen through the small screen and the large screen separately provided on the outside of the main body is simple, but also the bright small screen can be realized in a bright surrounding environment.
