DLP大屏幕显示系统 技 术 方 案 2008年月offers a smooth matt surface to the viewer with the vertical lenticular lenses facing the projector. The UCS is available in a Standard version and a Rigid version, which is optimized for cube installations in control rooms. This version is reinforced with a thicker acrylic front element, which makes the screen more rigid and enhances the vertical light distribution. = Ultra high contrast and sharpness = Superb centre-to-corner brightness uniformity = Wide horizontal viewing angles = Multiple options for focal length = Easy-clean surface = Compatible with LCD, DLP, LCOS, Light Valve and D-ILA projectors The dnp Ultra Contrast Screen (UCS) is developed exclusively for single lens projectors. The UCS has exceptionally good centre-to-corner brightness uniformity and displays bright, sharp images over a broad viewing area. The advanced optical lens system and the special UCS lenticular offer high tolerance to ambient light and provide special technologies for enhancing contrast. This makes the UCS well-suited for retrobox applications and multi-screen installations in high-light environments such as control rooms and Point of Sale locations. The UCS is a double element screen with four active lens surfaces. The ultra-fine resolution allows the screen to be viewed at very close range. And the easy-clean front surface makes it suitable for applications where the screen is likely to be touched. The front UCS lenticular The Fresnel lens on the rear element refracts projected light directly through the screen. The reverse UCS lenticular lenses on the front element distribute the light horizontally, enhance contrast and reduce the impact of ambient light.
