Is projection for dark rooms only?
Most of us think projection screens can only be used in dark spaces.
Therefore our home needs a dedicated darkroom for a home theatre, while businesses using projectors are bound to hold their meetings in the dark.
We know projection and ambient light in the room do not go together well. ultra-short-throw PET black crystal fabric projection screen can improve the situation,
It allows using projection screens in ambient light conditions.
But how does it do it?
It means the screen reflects the light coming to it from the projector back to the audience, while all other light is rejected (reflected in other directions).
One of the characteristics of projection screens is gain, which is the ratio of light reflected back from the screen surface.
ALR projection screens have a high gain (more than 1) and therefore give the viewers a brighter image. The bigger the gain, the brighter the image.
The biggest problem of ALR screens is a hot spot, which is simply the reflection of the projector lens.
Sometimes you don’t see a hot spot, but if you are looking at the screen and your eyes hurt, the screen is still hot-spotting.
Thanks to the specially designed, precise, lens-like curvature, this amazing screen deliver stunning images both in the dark and in a well-lit room.
The screen delivers amazingly bright and sharp images with a standard or long-throw projector.
You need to see it to believe it. The ultra-high gain ALR optical projection screen is a true miracle!
