Abstract

본 발명은 화면분할식 투사형화상표시장치에 관한 것으로, 고휘도의 백색광을 발광하는 광원(10)과, 상기 광원(10)으로부터 발광하는 백색광에서 다수의 원색을 가지는 광속들을 분할하는 광분리수단(20)과, 상기 광분리수단(20)을 통과한 광속들을 동일하게 n배로 배분하는 광선분할수단(30)과, 상기 광선분할수단(30)에서 n배로 배분된 광속들을 반사하는 반사경(40)과, 하나 또는 그 이상의 틈들을 가진 반사면으로 이루어지며 상기 광선분할수단(30) 및 반사경(40)에서 반사된 광들을 광량조절하는 제1 및 제2광량조절수단(50)(60)과, 상기 제 1 및 제 2 광량조절수단(50)(60)에 응답하여 광속들을 화면에 투사하는 투사렌즈(70)(71)와, 상기 투사렌즈(70)(71)에 응답하여 요구하는 화상을 구현하는 화면(80)을 포함한다. 따라서, 광량조절수단의 가공성을 개선하고, 또한, 고선명 및 고해상도를 구현할 수 있다.The present invention relates to a screen split type projection image display apparatus, comprising: a light source (10) for emitting white light having a high brightness, and optical separation means (20) for dividing light beams having a plurality of primary colors from white light emitted from the light source (10). ), A light splitting means 30 for equally n times distributing the light beams passing through the light splitting means 20, and a reflector 40 for reflecting the light fluxes multiplied by n times in the light splitting means 30; A first and second light amount adjusting means (50) (60) formed of a reflecting surface having one or more gaps to adjust the amount of light reflected by the light splitting means (30) and the reflector (40); Projection lenses 70 and 71 for projecting the luminous fluxes on the screen in response to the first and second light intensity control means 50 and 60, and images required in response to the projection lenses 70 and 71 The screen 80 is included. Therefore, it is possible to improve the processability of the light amount adjusting means, and to realize high definition and high resolution.
