Abstract
Description
Claims (4)
- 광원램프(10)에서 입사되는 광을 일정한 패턴으로 형성하는 소오스 스톱부재(12)와, 그 소오스 스톱부재(12)를 통과한 광을 필드렌즈(14)를 매개하여 수광하여 그 수광된 광에 대해 광량을 조절하는 형태로 반사시키는 광조절밸브모듈(16), 그 광조절밸브모듈(16)에서 반사되는 반사광을 컬러분리방식으로 투과시켜 투사렌즈(20)에 전달되는 투사 스톱부재(18) 및, 그 투사 스톱부재(18)에 화상시노에 기초하는 신호전압을 인가하여 컬러표시를 제어하는 제어유니트(22)를 갖추어 구성된 것을 특징으로 하는 투사형 화상표시시스템의 컬러표시장치.
- 제1항에 있어서, 상기 투사 스톱부재(18)에는 제1-제3컬러(RGB)의 투과를 위한 제1-제3컬러필터영역(18a,18b,18c)이 횡방향으로 구획되는 섹선별미러로 형성된 것을 특징으로 하는 투사형 화상표시시스템의 컬러표시장치.
- 제1항에 있어서, 상기 투사 스톱부재(18)에는 제1-제3컬러(RGB)의 투과를 위한 제1-제3컬러필터영역(18a,18b,18c)이 종방향으로 구획되는 섹선별미러로 형성된 것을 특징으로 하는 투사형 화상표시시스템의 컬러표시장치.
- 제1항 내지 제3항에 있어서, 상기 제어유니트(22)는 상기 투사 스톱부재(18)의 제1-제3컬러필터영역(18a,18b,18c)에 대해 화상신호의 필드기간에 RGB신호를 순차적으로 인가하여 상기 제1-제3컬러(RGB)신호가 얻어지도록 상기 투사 스톱부재(18)의 제1-제3컬러필터영역(18a,18b,18c)을 시분할 구동하도록 된 것을 특징으로 하는 투사형 화상표시시스템의 컬러표시장치.
