Abstract

이 발명은 입체영상용 액정 셔터 안경에 관한 것으로 액정 셔터에 고분자 분산 액정과 시력 보호 필름을 적용함으로써 종래의 배향막과 실 프린트와 편광판 부착과 같은 제조공정을 줄이며 제품의 단가를 낮추도록 하기 위하여, 구동레벨의 전압이 인가될때만 빛을 투과하는 고분자 분산 액정(42)과, 상기 고분자 분산 액정(42)에 전압을 인가하기 위한 투명 기판(43)과, 사용자의 시력을 보호하기 위한 보호필름(44)으로 구성된 좌우 액정 셔터(4,4')와; 상기 좌우 액정 셔터(4,4')가 교대로 개폐되도록 입체영상 텔레비젼 (5)에서 출력되는 전압 신호를 스위칭하며, 상기 스위칭된 전압신호를 상기 좌우 액정 셔터(4,4')의 투명 기판(43)에 출력하는 액정 셔터 구동부(2)로 구성되어짐을 특징으로 하는 입체영상용 액정 셔터 안경에 관한 것.The present invention relates to a liquid crystal shutter glasses for stereoscopic images, and to apply the polymer dispersed liquid crystal and the eye protection film to the liquid crystal shutter to reduce the manufacturing process such as the conventional alignment film, seal and polarizer plate, and to reduce the unit cost of the product, The polymer dispersed liquid crystal 42 which transmits light only when a voltage of a level is applied, the transparent substrate 43 for applying a voltage to the polymer dispersed liquid crystal 42, and the protective film 44 for protecting a user's vision Left and right liquid crystal shutters 4 and 4 '; The voltage signals output from the stereoscopic television set 5 are switched so that the left and right liquid crystal shutters 4 and 4 'are alternately opened and closed, and the switched voltage signals are transferred to the transparent substrates of the left and right liquid crystal shutters 4 and 4'. A liquid crystal shutter eyeglass for stereoscopic image, characterized by comprising a liquid crystal shutter driver (2) for outputting to 43).
