The term ‘ambient light rejecting”, or ALR is now an eternal part of AV industry nomenclature in terms of a screen feature that restricts ambient light from washing out a projected image. There are AV purists who don’t like the use of the word ‘rejecting’. ALR screans do the opposite of rejecting. Ambient Rejecting Projection Screen either divert or absorb the ambient light away from the viewer’s field of vision.
To those AV installers, ambient light is any atmospheric lighting which is indigenous to an indirect source of luminance that can be either inside, outside, naturally or artificially occurring. Normally, it’s any light source that is different from your projector threatening to wash out your image or otherwise impair its visual aesthetics. It incorporates but is not limited to the light coming through the windows as well as skylights from the outside, in wall-ceiling lights, track lighting, lamps, fireplaces, candles or even the light of your own video screen reflecting off the light-colored surfaces in your room.
The bottom line is, that most of the rooms don’t have 100% control over environmental lighting. As cool as a fully contained home theater room is, most households just don’t have any of them. Rather, homes are trending towards having large projection screens in multi-use living rooms, media rooms and dens as a means of replacing the household television set with a larger than life screen. Ambient Rejecting Projection Screen are just doing the same for them.
