GLASSVu GT72
Rear Projection Screen

The GlassVu GT72 is a dark gray screen with 72% transmittance of light projected onto its surface and haze measured at 96%. It is visible from a 150° angle to provide exceptional off-center viewing. The GT72 is our highest contrast GlassVu at 450:1. This allows for great separation of whites and blacks on screen for vivid images from video games and action movies, while the grey screen blends into darker settings when not in use. The GT72 is an outstanding performer for digital signage applications where high ambient light settings are an issue. You will notice that images are very crisp and true to the projected color.

GlassVu Rear Projection Screens are offered in sizes ranging beginning at 80 inches diagonal (2032 millimeters) to around 32 feet across (10 meters). Larger screens are possible by combining multiple panels measuring 5 feet wide (1.524 meters) into a single display.

  • High Ambient Light Digital Signage
  • Information Kiosks
  • Control Room Screens

transmittance

For polymer screens such as GlassVu, direct transmittance is the fraction of the incident intensity that does not deviate from the incident direction as light emerges on the other side of the screen. Restated, direct transmittance is the amount of projected light that passes through the screen and is not reflected or otherwise absorbed. When direct transmittance is greater than 90%, the screen is considered transparent.

haze

Haze is the percentage of transmitted light that in passing through the screen deviates from the incident beam by more than 2.5° from the normal incident beam. It is seen as the cloudy appearance of an otherwise transparent screen caused by light scattered from within the screen or from its surfaces.
