Abstract
본 발명은 배면타입의 프로젝션 티브이에 적용되는 스크린에 관한 것으로, 특히 확산면에 종횡방향으로 렌티큘러 형상을 갖게 하여 수평 뿐만아니라 수직방향으로도 확산이 이루어지게 함으로써 보다 넓은 시청범위를 갖도록 한 종곡률을 준 프로젝션티브이용 스크린에 관한 것이다. 본 스크린은 세로방향으로 소정의 곡률을 갖음으로써 확산제의 의한 확산효과보다 큰 확산효과를 갖아 수직방향의 시청범위를 보다 크게확대할 수 있다. 특히, 세로방향의 곡률을 조절함으로써 설치조건에 따라 시청범위를 조정할 수 있는 효과를 갖는다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a screen to be applied to a rear projection TV, and more particularly, to a screen having a lenticular shape in longitudinal and transverse directions on a diffusing surface, And more particularly, to a quasi-projection type projection screen. This screen has a predetermined curvature in the vertical direction, and thus has a diffusion effect larger than the diffusion effect by the diffusing agent, so that the viewing range in the vertical direction can be further enlarged. In particular, by adjusting the curvature in the vertical direction, the viewing range can be adjusted according to the installation conditions.
