FAQs: What are Optical Screens and how are they best used?

Projecting in brighter environments is becoming increasingly necessary and possible with newer technology available today. But even the brightest of projector need help from the screens to project their images with high quality and contrast. Optical screens provide a solution for situations when you need to present in high ambient light, but how they work is not well understood.

What is an optical projection screen?

An optical projection is a big screen with an advanced optical lens system, which enables control of the projected image for maximum impact – even in brightly-lit environments. While conventional front projection and rear projection screens spread the light in all directions, these screens enhance the image for optimum viewing by focusing and concentrating the projected light.

What is the benefit of an optical screen compared to other conventional screens?

Contrast is the key benefit because In bright projection environments it is crucial to achieving an outstanding image. You get blacker blacks, more vivid colours and brighter, sharper images. Conventional rear or front projection screens need darkness to be more effective because they reflect all available light not just the projector’s light, which creates creating poor contrast levels.

Low contrast ratios often cause eyestrain – studies show that for viewers to see detailed information clearly, the minimum acceptable image contrast is 15:1. This is NOT achievable using a standard white front projection screen in normal environments but is achieved and exceeded by some optical screens.
