Chapter One: Types of F ront Projection Screens
CHAPTER One: Types of Front Projection Screens
oo often the decision concerning what size, type, and gain projection screen going into a home theater, or other display application, is made without a great deal of thought. This is unfortunate because the projection screen is a critically important element in a video display system. It is no less than the final link in the picture deliver process and the visual focus of the entire room. Furthermore, we have seen the quality of many home theater rooms compromised because of casual and thus improper screen selection. Before you choose one, we recommend spending some time reading this design guide and getting a feel for how different screen features affect the image you see.
We recommend that you consider a curved screen if you anticipate having a substantial amount of light in the room from windows, inside lights, etc. Often they are the only solution for getting a high quality front projected image in a room of this type. Front-projected fixed flat screens are one of the most common ways to view projected video images. In home theaters they are exceedingly popular because they closely resemble their counterparts in commercial theaters. Fixed flat screens typically consist of a vinyl screen material with Velcro or snaps on the edges which is stretched across an extruded aluminum frame coated with a flat black epoxy finish. These screens are not only very easy to install, they are quite affordable and are available in 4:3, 16:9 and other aspect ratios. Keep in mind that flat screens are very sensitive to light in the room, thus flat screens tend to look best in dark rooms. If you can control the room lighting, (i.e. with drapes, blinds and light dimmers) then flat screens are an excellent screen choice. Note: a new option for fixed flat screens is a black velvet finish applied to the frame. This finish is very handsome and eliminates the glare of the video image overscanning the active picture area. If your want your projection surface to retract when not in use, consider a front-projected manual retractable screen. These screens operate similar to window shades. You pull them down for use and let them roll up when the show is over. Manual retractable screens are very affordable, are available in 4:3, 16:9 and other aspect ratios with a matte-white screen material. The screen housings can typically be ordered in black, white or gray colors at no extra charge. An important feature that every home theater designer will appreciate is Vutecs unique screen mounting system. As illustrated on page 46, this feature is standard on Vutecs manual retractable and several of the motorized retractable screens.The secret of this mounting system is a simple channel that runs the entire length of the screen.

Types Of Front Projection Screens Available High gain curved screens consist of reflective foil surfaces mounted on large curved plastic backings. Sold by Vutec under the Ultra-High Gain Curved Screen brand name, these screens offer gains of over 13 and display ultra-bright, ultra-high contrast images. Although curved screens were mandatory several decades ago when video projectors offered much less light output than today, they are still a very popular option for use in rooms with high ambient light levels. The reason concerns the physical behavior of the curved surface itself. Because they are designed to direct the major portion of the projected image back into a reduced viewing cone, they are equally adept at rejecting room lighting off to the sides. In other words, design your room with lights and windows off to the sides (i.e. not directly opposite the screen), and with a curved screen you will get a bright, high contrast image, much higher than if you used a flat screen. Curved screens weigh very little, are easy to install and can be easily cleaned. Historical note: In the old days curved screens were made of Kodak Ektilite, an uncoated aluminum material that could not be cleaned. To this day some people still worry that curved screens cant be touched. Todays curved screens are completely washable.

How Screens Are Measured

A = Screen Size Diagonal B = Black Leader (on rolldown flat screens) typically adjustable from 2 to 8 C = Black Borders, typically 1 on Curved Screens, 2 Flat Screens
It allows the screen mounting clips to be placed almost anywhere behind the screen, or above the screen. The beauty of this system is that one does not have to fabricate anything to hang the screen from. The clips are simply attached to supporting studs behind, or above, and can be spaced roughly on the right and left sides of the screen. In the old days, installing a screen via the mounting tabs on the housing ends could take several hours. Floating Mounting Brackets makes a screen installation just a 5-10 minute job and often requires just one person. For those that want the luxury of automation, consider a front-projected motorized rolldown screen. These screens are powered by a 120 or 220VAC power source and can be lowered and raised via a switch. Many home theater installers go a step further, and wire them to a relay that automatically lowers the screen when the system is turned on. Another control method is to interface the relay with an Infrared controller so that the screen can be controlled via a hand held remote control. These methods and several others are covered in Chapter 8 of this handbook. Offered under various brand names, standard motorized screens are available in 4:3, 16:9 and other aspect ratios with materials that range in gain from.85 to 3.1. Trap door versions are also available. For those who want a very flat surface but in a motorized format, Vutec manufacturers a "tab-tensioned" motorized rolldown screen line. These screens sport external suspension cables that pull the screen surface taut thus eliminating screen wrinkles and edge curl. Tab tensioned screens are more expensive than their free hanging counterparts but offer an extremely flat surface in a motorized housing. Tab-tensioned motorized screens are available in 4:3, 16:9 and other aspect ratios with

materials than range from.9 to 3.0 gain. Often consumers demand unobtrusive equipment in their home theater rooms, in or other presentation environments. In other words, they dont want to see the technology that creates the A/V experience anymore than what is absolutely necessary. If you think about it, this is really extreme.When you watch a movie at a commercial theater all you see is a big picture and sound. No speakers, no projectors, no blinking lights, etc, just the pure movie experience. Well for those who want to hide the technology, Vutec offers several models. All four of the screen manufacturers offer Motorized Trap Door Screens. These are assemblies that are designed to mount in the ceiling. As the diagrams on the following pages show, there actually is a trap door system that retracts flush with the ceiling when the screen is raised. The housing itself is made of a high density composite wood material and the doors are available primed for paint or in a custom laminate for a extra charge. Rear Projection Screens When you go to your local A/V retailer and look at televisions in the 50 to 80 range, you are looking at rear screen projection systems. The pictures on these are generally bright, high contrast and can be easily seen in well lit rooms. Those who are looking for this kind of performance in larger screen sizes should consider a custom-built rear screen system. These systems are typically built into the wall of a home theater room, or board room, and can offer outstanding performance. We cover these systems in another of our CinemaSource Design Guides.

Glossary of Screen Terminology
CHAPTER TEN: Screen Terminology Glossary
Gain: A measurement of the amount of light radiating perpendicularly from a screen. Unity gain (a gain of 1) is generally standardized via a block of magnesium carbonate. LCD: Liquid Crystal Display, a technology of video display that uses liquid crystal shutters to modulated the light passing through the imaging chips. Also refered to as Transmissive LCD technology. Lens Speed: The ability of a lens to pass light. Expressed in a ratio, it is the focal length of the lens divided by the effective diameter of the lens. A fast lens passes more light and gets a lower rating. Lumen: The quantity of visible light falling on a 1 square foot surface of a sphere 1 foot in radius as radiated by a source of 1 standard candle. This specification is often used to rate the light output of video projectors. Look for ANSI lumen ratings, it is a standardized measurement. Luminance: The brightness of a light source measured in foot-lamberts. Pixel: A picture element. On digital devices, images are usually constructed of pixels fields divided into rows and columns. Resolution: The limit of a displays ability to present fine detail. Optical resolution is usually the number of lines seen, video resolution is usually the number of line pairs seen. Scan Lines: A CRT-based video display creates images by rapidly sweeping electron beam across a phosphor target. As these lines are swept from top to bottom they create scan lines. Throw Distance: The distance from the screen surface to a video display device. This is an important number used in the installation of a video display. Viewing Angle: An angle that specifys a particular viewing location measured from a perpendicular from the screen surface.

Ambient Light: The light in a viewing room produced by sources other than the screen Aspect Ratio: The numeric relationship between a screens height and width. Generally speaking an aspect ratio defines a shape. Black Drop: On a rolldown flat screen this is the area that is black on the top or bottom of the picture areas. Brightness: A viewers subjective response to a displays luminance Contrast ratio: The numeric relationship between the brightest and darkest portions of a video display. It is generally expressed in foot-lamberts as a ratio of max/min. CRT: Cathode ray tube, a vacuum tube where electrons are drawn to phosphor targets via high voltage potentials. This is the technology behind standard picture tube-type televisions. DLP: Digital light processor, a technology based on the Texas Instruments DMD micromirror imaging chips. These chips have a field of reflecting mirrors that can be modulated to produce video images. Foot-Lambert: A unit of luminance equivalent to 1 lumen per square foot. Fresnel Lens: A device constructed of a large number of closely spaced concentric circles cut into an optical surface. The circles are cut so that they reduce the incident bend angles of the projection source and collomate the light into one beam.

NOTES:
