Ambient light rejecting (ALR) materials are the logical choice for today’s commercial workplace or residential living space. It is just too inconvenient to always make the room dark when you want to see a large projected image. ALR screens allow a projection display to be used more like a TV display in a room with high levels of ambient light. This also includes in-ceiling light sources that are especially prolific in in commercial locations. Ceiling light rejecting (CLR) materials are ALR materials also but are specially formatted to more specifically reject overhead lighting by as much as 95%.
