Rear Projection Screens and Material
 |
faith rear projection screen material is a transparent substrate acrylic, within a permanently bonded optical coating. This coating is an emulsion of microscopic particles, which function as refractive lenses. It diffuses and distributes projected light, reproducing the projected image. The optical coating may be formulated |
|
for varying levels of brightness, light distribution, is resistant against mild abrasion and can be cleaned with soap and water. MATERIALS faith rear projection screens are cast on the finest plate glass
using fine, clear (or dyed) acrylic as screen material. Acrylic
is lightweight, durable and break-resistant and easy to install.
faith rear projection screens are manufactured in the following
sizes and thicknesses.
The density of the diffusion material within the screen comes in 3 different levels. The reason is that the more diffusion material, the wider the angle of viewing but the gain will be less when viewed directly. However, if less diffusion material is used then the picture will be brighter when directly viewed, but will be darker in comparison when viewed from the wider angle. COLOURS All faith rear projection screens are available in three formulations (N5, N7, 00), this will allow the specifier to select the optimum image contrast level for the planned installation. 00 - White - Neutral white tint. Low contrast with some loss in colour rendition. Offers slightly higher brightness levels and enhances the rear screen’s ability to reflect a laser pointer beam. Not recommended for computer graphic/data displays with dark backgrounds and light text characters. N5 - Neutral Grey - Standard formulation medium grey tint. Normal contrast levels and good colour rendition. Brightness levels are uniform throughout entire viewing cone. Suitable for all projection formats and images (video slide, LCD, computer data etc). N7 - High Contrast - Dark grey tint. Exceptional contrast and colour rendition. Excellent light dispersion properties for uniform brightness from any viewing angle. Highly recommended for computer generated data displays with light or bright text against a dark background. Dark colours and black are reproduced with remarkable accuracy. Outstanding dark colours. N7 coatings perform equally well with static and moving displays.
