These rear projection surfaces are tensioned on four sides to
attain a perfectly flat surface and used in projection screens in
which the material is tensioned.
Retrotex
(
rear projection)
A neutral grey vinyl rear projection screen that provides contrast
enhancement while maintaining uniformity and color rendition.
A versatile rear projection surface, Retrotex is a good choice for
applications with good control over ambient light. This is a vinyl
based surface.
Da-Tex
®
(
rear projection)
Da-Tex
®
is a special, transparent material which is designed for
situations where the projector is located behind the projection
screen. The high reflection properties of Da-Tex
®
mean that this
material may also be used in rooms with high ambient light
levels or in combination with a projector with a low light output.
This increased reflection does, however, result in a more narrow
viewing angle, making Da-Tex
®
more suitable for installations
with a narrow seating configuration. This is a vinyl-based
surface.
Benefits of rear projection:
Image quality is superior to front projection.
Less loss of contrast.
With rear projection there is no projector in sight and all AV components
can be concealed in the projection room eliminating fan noise.
With rear projection the presenter or teacher can walk in front of the
screen without affecting the projection.
