Abstract

본 발명은 2개의 AMA를 사용하여 해상도를 2배 증가시킬 수 있는 투사형화상표시장치에 관한 것이다. 본 발명에 따른 투사형화상표시장치는 M×N개의 화소들로 나타내는 투사형화상표시장치에서, 백색광을 발광하는 광원과; 상기 백색광을 분리하여 다수의 원색을 가지는 제1차 광속들을 발생시키는 광분리수단과; 상기 제1차 광속들을 발생시키는 광분리 수단과; 상기 제1차 광속들을 각각 평행하게 하며, 상기 제1차 광속과 반대방향으로 진행하는 제2차 광속들을 집광하는 평행렌즈와; 상기 제1차 광속을 반으로 분할하며, 상기 제1차 광속과 반대방향으로 진행하는 제2차 광속들을 합성하는 90°거울과; 상기 90°거울에 의해 분할된 각각의 제1차 광속을 확대하고, 상기 제1차 광속과 반대 방향으로 진행하는 각각의 제2차 광속을 축소하는 수단과; 각각 확대된 제1차 광속을 소정의 제어신호에 따라 서로 다르게 반사시켜 제2차 광속을 발생시키는 광로조절수단과; 상기 광분리수단으로부터의 상기 제1차 광속들을 상기 평행렌즈로 반사시키며, 상기 평행렌즈로부터의 상기 제2차 광속의 광량을 조절하는 광량조절 수단과; 상기 광량이 조절된 제2차 광속들을 합성하여 화상을 나타내는 화면을 포함한다. 따라서 현재 제조기술로 생산가능한 AMA를 2개 사용하여 광학계를 구성함으로써 2배의 해상도를 얻을 수 있다.The present invention relates to a projection image display device capable of doubling the resolution by using two AMAs. According to an aspect of the present invention, there is provided a projection image display apparatus comprising: a light source for emitting white light; Optical separation means for separating the white light to generate primary light beams having a plurality of primary colors; Optical separation means for generating said primary luminous fluxes; A parallel lens for paralleling the first luminous fluxes and condensing second luminous fluxes running in a direction opposite to the first luminous flux; A 90 ° mirror for dividing the first luminous flux in half and synthesizing the second luminous fluxes traveling in a direction opposite to the first luminous flux; Means for enlarging each primary luminous flux divided by said 90 [deg.] Mirror and reducing each secondary luminous flux traveling in a direction opposite to said primary luminous flux; Optical path adjusting means for reflecting each enlarged primary light beam differently according to a predetermined control signal to generate a second light beam; Light amount adjusting means for reflecting the first primary light fluxes from the optical separation means to the parallel lens and adjusting the amount of light of the second secondary light flux from the parallel lens; And a screen displaying an image by synthesizing the second luminous fluxes whose light amount is adjusted. Therefore, by constructing an optical system using two AMA that can be produced by the current manufacturing technology, it is possible to obtain twice the resolution.
