산화막 증착을 통한 이중스크린 3D 프로젝션 디스플레이 스크린용 산란형 편광필름의 편광유지도 개선

Abstract

Keeping the polarization direction of the projection light unchanged is of crucial importance for high quality of images on a double-screen 3D projection display system. It has been found that the deposition of oxide layers on the surfaces of scattering polarizer film results in an improvement of polarization maintenance property of the film. The secondary image formed on the front screen by the light scattered from the rear screen decreases by 30% through the application of oxide layers on both surfaces of the screen. Since the oxide layer can also be used as an anti-reflection (AR) coating of the film, this method is very effective for the projection display applications.
