ALR is an acronym of Ambient Light Rejecting.

ALR screen is specifically designed for ultra-short throw projectors.

It negates the washout effects of ambient light while maintaining superb picture quality under normal room lighting conditions. The screen is the perfect solution for rooms that have little or no control over incidental light.

For example, VAVA has this kind of screen.

The engraved toothed grid structure on VAVA’s ALR screen’s surface filters out up to 92% of the overhead ambient light, which enhance the contrast and color saturation of the projected images.

You can buy this kind of screen to improve your image experience.
