The surface particles used in manufacturing a screen determine its maximum resolution.

Current screens typically can not deliver resolutions higher than VGA, but the 10X and 20X screens can be used with all current and future video projection systems with resolutions up to 9 million pixels.

Our 20X screens produce an image that is sharper, brighter and more accurate than all other conventional screens. 

Under normal room lighting, the images from conventional screens become faint and blurry, while the 20X screen images continue to be sharp and bright.

20X Screen

Glass bead screens are regressive.

When a projector is installed on the ceiling, they reflect most of the light back to the ceiling.   When the projector is placed on a stand or table, they send most of the light back to the floor. In both cases, the image definition is lost.

20X screens send the light to the audience, regardless of where the projector is mounted in the vertical plane. The audience gets the full benefit of the 20X's exceptional brightness and image quality.

Our 20X screens (A) have a proper viewing angle of 60º and a viewing distance of up to 1,000 feet. Beyond 1,000 feet, the image definition does not drop off. At wide viewing angles it provides a gain 3 times greater than any conventional screens.

Our 10X screens (B) have outstanding image resolution and high gain, delivering 9X performance even at 180º viewing angle.

 

 

* What is ANSI and ANSI Lumens?

ANSI is an abbreviation of American National Standards Institute. ANSI Lumens are the average brightness of 8 areas of a screen, except the brightness of the center, when you divide a 40" screen in  9 equal parts and project an image onto the screen. Normally it is used to express the brightness of a projector.

* What is Gain?

Gain is the reflective rate of a screen. The amount of light reflected on a carbon white block is 1 gain. Normally a white paper is 1 gain and a mirror is 100 gain.
