Screen requirements

This projector is used to project the image onto flat screens. However, the brightness and viewable range will vary depending on which type of screen is used.

When selecting a screen, check the characteristics of the screen to ensure that it is suitable for the intended place of use.

Screen characteristics (reference)

Screen type Polarized screen

Screen characteristics

Because the surface of the screen has been treated to make it polarized, it will only reflect light from a single direction. Consequently, if you use such a screen with an LCD projector, a clear image can be obtained even in bright rooms because the screen hardly reflects any extraneous light.

White screen

Silver screen

Beaded screen

This type of screen can be seen from anywhere, so there are no limits on the viewing position. However, the surrounding walls should be darkened as in a movie theater, otherwise a clear picture cannot be obtained.

This type of screen gives a picture which is 2-4 times brighter than a white screen. A variety of types are available from different manufacturers, and each type has different brightness characteristics. Some also have restrictions on the possible range of viewing positions.

Care should be taken with screens that have a high gain, as these types of screen can cause color distortion at the left and right edges.

This type of screen is recommended when the projector is suspended from the ceiling.

This type of screen is similar to the silver screen, except that no color distortion occurs at the left and right edges. Moreover, most of the light is reflected at the same angle as the angle of incidence.

This type of screen is recommended when the projector is placed on the floor.
