Clear Vision screens combine the benefits of rear projection with advanced optical lens technology. The image is projected on the rear side of the screen to achieve the sharpest and brightest possible image. And the builtin lens technology enhances the perceived contrast and absorbs ambient light. The Holo Screen features an advanced holographic film that displays images rear projected from 30°– 35°. All other light, such as sunlight and instore lighting, is ignored. The result is a remarkably sharp, transparent image that is especially useful in shop windows. Other Clear Vision screens feature advanced coatings and optical filters that make them tolerant to ambient light. The result is bright, sharp images even in brightly-lit shop environments.
