SECTION 11138
REAR PROJECTION SCREENS
***** Draper manufactures four types of rear projection screen:
Cinescreen - A diffusion type rear projection screen consisting of a transparent
substrate with a permanently bonded optical coating which diffuses and distributes
projected light. The coating is an emulsion of microscopic particles, each functioning as
a refractive lens.
IRUS - Infinite Resolution Uniformity Screen - An acrylic rear projection screen
designed for use with single lens, high resolution technology capable of providing
optimum displays with uniform, crisp, ultra-fine images.
DiamondScreen - Cast acrylic high intensity screen with an integral lens system and
embedded diffusion material. The brightness of DiamondScreens is up to three times
that of conventional rear projection screens.
Vortex - Cast acrylic, high intensity screen with an integral lens system and embedded
diffusion material. Since diffusion material is embedded, it cannot be scratched or
damaged. Vortex is designed for use with single lens projectors without moiré patterns.
The projected light is collimated then diffused evenly, allowing for use in videowalls
and rooms with tiered seating patterns.
This section also covers four types of aluminum frames used for rear projection screens
and three systems for video walls. A video wall is a custom designed, framed array of rear
projection screens used in command centers, control rooms, and other facilities where
detailed visual information is displayed. Video walls are typically used in conjunction with
rear projector support framing systems specified in SECTION 11139 - REAR
PROJECTION SYSTEMS.
There are various options for substrate material, formulation of optical coating, tint of
optical coating, surface treatments, sizes, method of installation, framing, and frame finish.
Refer to Draper product literature for availability of options, standard sizes, and
guidelines for selection of screen type. Various options are listed in this specification
section and the specifier will need to select the appropriate options, verify their availability,
and delete non-applicable options.
When Draper rear projection screens with Cineflex Rear Projection flexible viewing
surfaces are to be specified, use one of the following:
SECTION 11131 - MANUALLY OPERATED PROJECTION SCREENS
SECTION 11132 - MOTORIZED PROJECTION SCREENS

A. Type: Rigid rear projection screen consisting of transparent substrate with
permanently bonded optical coating [factory installed in aluminum frame] [field
installed in site constructed frames] including gaskets, setting blocks, fasteners, and
other components necessary for complete installation; Cinescreen as manufactured
by Draper, Inc.
***** Cinescreen is provided with the following two types of transparent substrate.
Thickness of substrate is determined by screen size.
Cineglass - Select quality plate or float glass and provides maximum sound isolation
and scratch resistance. For Cineglass, maximum screen size is 6 by 8 feet (1.8 m by

inch (10 mm) and 1/2 inch (13 mm) thicknesses.
Cineplex - Select quality clear acrylic glazing and is lightweight, durable, and break
resistant. For Cineplex maximum screen size is 100 by 150 inches (254 cm by 381
cm) for 1/4 inch (6 mm) thickness and 104 by 240 inches (264 cm by 609 cm) for

***** Draper, Inc. offers the following six optical coatings for Cinescreen rear projection
screens. Selection of optical coating is influenced by projector light output, audience
pattern, screen aspect ratio, and ambient light level in audience area. Refer to Draper
product literature for assistance in selection of appropriate optical coating. Coatings are
formulated to provide varying levels of brightness over different viewing angles. Screen

surfaces are rated according to gain which is a measure of brightness relative to a block of
magnesium carbonate which serves as the standard for 1.0 gain. A higher gain indicates an
increase in brightness. Peak gain is measured directly in front of the screen at 0 degrees
viewing angle. Gain will decrease with an increase in viewing angle.
Cine 10 1.0 peak gain and half-gain at 50 degrees.
Cine 13 1.3 peak gain and half-gain at 33 degrees.
Cine 15 1.5 peak gain and half-gain at 31 degrees.
Cine 18 1.8 peak gain and half-gain at 28 degrees.

manufactured by Draper, Inc.
***** All Draper optical coatings are available with three optical tints:
Cine HC - High contrast dark grey tint.
Cine NG - Medium grey tint normal contrast tint.
Cine W - Neutral white tint.
Selection of optical tint is influenced by type of projector, contrast and legibility of
projected image, ambient light level in audience area, acceptable color when screen is not
in use, and use of laser pointers. Refer to Draper product literature for assistance in
selection of appropriate optical tint.
D. Optical tint: Provide modifier for optical coating to enhance image contrast and
color value; [Cine HC - Dark Grey Tint] [Cine NG - Medium Grey Tint] [Cine W Neutral White Tint] as manufactured by Draper, Inc.
***** Cinescreen is typically installed with coated side toward audience since optical
coating controls glare. However, coating is vulnerable to accidents and abuse and can be
damaged by pointer, pencils, pens, fingernails, grease, oil, chalk, markers, and improper
cleaning. Draper ArmorKote is applied over optical coating to protect surface from
abrasion, abuse, and solvents. Include the following paragraph if protective coating is
required. *****

1.
High resolution, excellent contrast, brightness, and superior color reproduction
are uniform throughout total screen area.
***** Gain is a measure of the brightness of the projected image. A higher number
indicates greater brightness. Typically projectors produce an image which is much
brighter at the center than at the edges. Hence the highest gain is experienced by viewing
the image from directly in front of the screen with 0 degrees viewing angle. The gain will
typically decrease as the viewing angle is increased. Uniformity of the projected image is
indicated by the differences in gain at 0 degrees and at other viewing angles. *****
