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.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제 3도는 본 발명에 따른 스크린의 구조를 나타낸 사시도.FIG. 3 is a perspective view showing the structure of a screen according to the present invention; FIG.

Claims (2)

배면부에 형성된 렌티큘러렌즈로부터 광을 집광하여 전면부에 등격 형성된 블랙스트립들 사이에 종방향으로 돌설된 렌티큘렌즈를 통하여 화상을 포함한 광을 외부로 확산투사하는 배면투사형 티브이스크린에 있어서, 상기 스크린의 전면 또는 배면의 각 렌티큘러렌즈들을 세로방향으로 소정곡률을 주어 렌티큘러 형상을 갖게해 세로방향으로도 소정의 확산각을 형성한 것을 특징으로 하는 종곡률을 준 프로젝션티브이용 스크린.A rear projection TV screen for diffusing and projecting light including an image through a lenticular lens projected in a longitudinal direction between black strips formed on a front portion of the screen by condensing light from a lenticular lens formed on a rear portion of the screen, Characterized in that each lenticular lens on the front surface or the back surface is provided with a predetermined curvature in the longitudinal direction so as to have a lenticular shape so that a predetermined diffusing angle is also formed in the longitudinal direction. 제 1항에 있어서, 상기 확산각은 상기 주어진 곡률에 따라 결정되어 시청범위가 결정됨을 특징으로 하는 종곡률을 준 프로젝션티브이용 스크린.2. The screen according to claim 1, wherein the diffusion angle is determined according to the given curvature to determine a viewing range. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
