Grey Crystal Optical Surface
The Cynthiascreen Grey Crystal ALR material is engineered to provide an ideal balance between brightness, contrast, and ambient light resistance. Built on a high-quality PVC substrate and coated with a specially formulated optical layer, the material enhances image clarity while maintaining natural color reproduction and excellent viewing uniformity.
The fine-textured Grey Crystal surface utilizes directional reflection technology to efficiently direct projector light toward viewers while reducing the impact of surrounding ambient light. This optical design improves image visibility in living rooms, conference rooms, and other environments where complete light control may not be available.
With a gain of approximately 0.8 and ambient light rejection performance of up to 70%, Grey Crystal material offers brighter images than many conventional ALR surfaces while maintaining wide viewing angles and excellent color accuracy.

Grey Crystal ALR Screen Material
The Grey Crystal screen material consists of a durable PVC substrate combined with a precision optical coating. The surface features a refined micro-textured finish that enables controlled light reflection while preserving image uniformity across the entire screen.

How ALR Screen Work
Traditional white projection screens reflect light in all directions, including ambient light from windows, lamps, and surrounding environments. This often results in washed-out images and reduced contrast. Grey Crystal ALR technology utilizes directional reflection principles to selectively reflect projector light toward the viewing area while suppressing part of the surrounding ambient light. As a result, viewers experience: • Brighter Images • Better Contrast • Improved Black Levels • More Accurate Colors • Enhanced Daytime Viewing Performance
