Front screen installations

In front screen installations, the projector and audience are positioned in front of the screen, which
can be flat or curved.
Flat screens offer a gain of about 1.0 with a viewing angle just less than 180 degrees. This type of
screen reflects incident light equally in all directions so the audience can see the display from
various angles.
Curved screens have a gain greater than 1.0 with a viewing angle much less than 180 degrees. This
type of screen does not reflect incident light equally in all directions; instead it is concentrated in a
viewing cone. The audience sitting within the viewing cone area see a brighter image than those
sitting just outside the area.
Rear screen installations
There are two basic types of rear screens:
• Diffused—A diffused screen has a surface which spreads the light that strikes it. Purely
diffused screens have a gain of less than 1.0. The advantage of the diffused screen is its wide
viewing angle, similar to that of a flat screen for front screen projection. This type of screen is
suitable when a wide viewing angle is required but there is low ambient room lightening.
