TECHNOLOGY: SHOWCASE 49 Elite screens reject ambient light
Elite’s fl agship screen material, the DarkStar ALR, comes from the company’s Elite Prime Vision line of projection screens for custom installers. The light-rejecting screen features material that fi lters out ambient light, thus attaining fl atpanel brightness whether the room lighting is on or off . The screen has a 1.4 gain material that has been engineered to incorporate optical fi lters that
actively refl ect a projected image while preventing ambient light from washing out the picture. The 0.4mm thick retro-refl ective material has been designed specifi cally for the home theatre environment. The screen also off ers a 16% vertical half-gain and 35% horizontal half-gain. A micro-serrated
fi ltration design ensures a retro-refl ective return while refl ected ambient light is reduced by 95%, according to the company. This technology enables the material to provide six times the contrast performance of a matt white screen in test rooms with brightness levels in excess of 50 foot-lamberts. The combination of retro-refl ective fi lters and neutral black contrast layers creates an image where
black-level details are easily seen without compromising the colour balance. In addition to this, a durable surface coating diff uses the light to eliminate hot-spotting, glare or other visual artifacts commonly encountered with higher-gain screens.
Screenline engineers simple installations
The current trend in the education sector is for interactive whiteboards – whether that is using projectors or through fl atpanel displays. For the former, the idea behind Screenline’s ScreenApp is to make installation of the projection surface as simple as possible. ScreenApp is a self-adhesive projection and whiteboard
surface that can be installed simply and quickly. The cleverly designed material uses the properties of a mouse
pad: rigid and fl at on the surface and soft at the rear. This helps with installation requirements, as the material will mould itself to bumpy or slightly nonconforming surfaces. It can adhere to surfaces including composites and laminates, plaster, wood, PVC, glass or even old blackboards. What’s more, a self-adhesive back uses technology that prevents air from being trapped underneath, helping to avoid the formation of bubbles. The material is repositionable, allowing the installer to change
the position of the screen numerous times without damaging the product. The board’s polypropylene front material is non- glare, with a high marker sliding coeffi cient to make it suitable for video projection as well as interactive whiteboard uses. It can work as a whiteboard on which a person can write with
both dry and permanent markers, and as a projection board for interactive video projectors.

giving the ceiling a clean appearance with no slot opening. To protect against damage, the screen is fl ame retardant, mildew resistant, and available in
either matt white [1.0 gain] or matt grey [0.8 gain]. In addition, all the mounting hardware is included. Versatility is also key for the Spirit Series. Installation options include wall, ceiling, or cable
suspended operation. Twenty-inch black drop for 16:9 models and 14in black for 16:10 models are also available. Standard sizes include 92-120in HDTV format (16:9) and 95-123in wide PC format (16:10).
Custom sizes are also available. The Spirit Series also comes with infrared eye, infrared eye extension port and extension
