Note:long throw and short-focus projector difference
A telephoto projector projects a 100-inch screen that requires a distance of 6 feet (about 1.9 meters) or more, and requires enough space to be used.
The distance required for a short-throw projector to project a 100-inch screen is 4.5 feet (about 1.3), which is suitable for use in conference rooms or classrooms.
There is also an ultra-short-focus projector that projects a 100-inch screen with a distance of 15-20 inches (about 0.5 meters), which is suitable for use in small places such as rooms.
Advantages:
1.UST Screen material,anti-ambient light.
2.Ultra-narrow frame picture,black side 1cm,more refined appearance,Visual effects are more attractive.
3.Suitable for home theater,research institutions, government agencies, command centers, or other entertainment venues.
4.The UST screen is a high-tech product designed and manufactured for high-luminance projection environments,especially suitable for ultra short focus projectors.Lens projection has a special optical structure , Ambient light capable of absorbing grating “black film”, can control the direction of the”microprism” of the optical path.it has special “micro structured surface diffusion film”and high reflectivity. High-tech materials such as “bead reflective layer” have made a perfect combination and difference.
