Abstract

두개의 액정 봉입용 유리 기판, 하나의 유리 기판의 내면에 형성된 반사층 및 두 유리 기판 사이에 봉입된 PDLC 층을 포함하여 구성되는 반사형 PDLC 패널을 이용한 프로젝터 시스템이 개시되어 있다.A projector system using a reflective PDLC panel comprising two glass substrates for liquid crystal encapsulation, a reflective layer formed on an inner surface of one glass substrate, and a PDLC layer enclosed between two glass substrates is disclosed.

일반적으로 액정을 이용한 표시 장치 또는 투사 장치가 갖는 문제는 다른 방식의 장치에 비해 콘트라스트가 만족스럽게 재현되지 못하는 점이다. 이와 같은 콘트라스트의 문제를 반사형 PDLC 패널을 사용함으로써 투과 모우드와 비투과 모우드 상태에 있는 액정 셀 사이의 콘트라스트를 증가시키게 된다.In general, a problem with a display device or a projection device using a liquid crystal is that the contrast is not satisfactorily reproduced as compared with other types of devices. This problem of contrast increases the contrast between the transmission mode and the liquid crystal cell in the non-transmissive mode by using a reflective PDLC panel.

반사형 PDLC 패널과 이를 이용한 프로젝터는 흑백의 화상 자료 뿐만 아니라, 다색 다계조의 화상 자료를 재생하는 표시 장치 또는 투사 장치로 사용될 수 있다.A reflective PDLC panel and a projector using the same may be used as a display device or a projection device for reproducing not only black and white image data but also multicolor multi-gradation image data.
