이하, 본 발명에 의하여 제조된 스크린의 사용에 대하여 설명하면 다음과 같다.Hereinafter, the use of the screen manufactured according to the present invention will be described.

상기한 바와 같이 표면에 요철처리된 산란층(11)을 형성한 투광성시트(10)의 이면에 반사층(20)을 형성하고 상기 반사층(20)에 투광차단층(30)을 형성하여 구성한 본 발명에 영상기기로부터 영상이 투사되면, 투사된 빛은 표면에 산란층(11)이 형성된 투광성시트(10)를 관통하게 되고, 관통한 빛은 반사층(20 )에서 반사되어 다시 투광성시트(10)를 관통하며 영상을 형성하게 된다. 이때, 투광성시트(10)를 관통하여 매질이 다른 공기중으로 발산되는 빛은 매질의 차이와 요철에 의하여 복합적으로 산란되므로 그 시야각이 최대 180°까지 확보되고 게인 의 값이 2 이상이 되게 되며 영상기기의 투사된 영상의 밝기 관계없이 선명하고 심도 있는 영상이 표현되게 되는 것이다.As described above, the present invention is configured by forming a reflective layer 20 on the back surface of the translucent sheet 10 having the concave-convex scattering layer 11 formed thereon, and forming a light blocking layer 30 on the reflective layer 20. When the image is projected from the imaging device, the projected light passes through the translucent sheet 10 having the scattering layer 11 formed on the surface thereof, and the penetrated light is reflected by the reflective layer 20 to again transmit the translucent sheet 10. It penetrates and forms an image. At this time, the light emitted through the light-transmitting sheet 10 to the other medium is scattered by the difference between the medium and irregularities, so that the viewing angle is secured up to 180 ° and the gain value is 2 or more. The clear and deep image is expressed regardless of the brightness of the projected image.
