Optical Technology The power of projected images

The optimal viewing experience

Until recently, projection on big screens was only possible in a darkened room. Now, thanks to dnp’s optical screens and contrast-enhancement technologies, you can project high-quality big screen images in any environment.

An optical projection screen from dnp is not a traditional front projection or rear projection screen. It is a big screen with an advanced optical lens system, which enables you to control 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, dnp screens enhance the image for optimum viewing by focusing and concentrating the projected light.

Different screen types suit different projection environments, which is why dnp manufacture the world’s most extensive range of high-contrast screens. Depending on where you want to project, you can choose between three main categories: 
front projection screens, optical flat screen solutions and rear projection screens for built-in solutions.

Projection in high ambient light

dnp manufacture the world’s broadest range of optical front projection and rear projection screens for all kinds of settings including: Conference- and meeting rooms, Control rooms, Education, Retail, Airports, Sports bars, Sports arenas, Home entertainment, Worship and TV studios.

Our screens can be hung in free space or built into walls, cubes, big screen tv sets and mobile retro boxes. Each optical screen type gives you the freedom to choose between several features including enhanced contrast, brightness, resolution and image uniformity. This means you can select a screen that meets the exact demands of your projector and installation environment.

Yesterday the screen was the limit. Today it’s your imagination.

Contrast is the key

In bright projection environments contrast is crucial to achieving an outstanding image. Conventional rear or front projection screens are associated with darkness, curtains and blinds. They reflect all available light not just the projector’s light, creating poor contrast levels. These low contrast ratios often cause eyestrain – and make it hard for the audience to concentrate.

Empirical studies show that in order for a viewer to be able 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. That’s why, in 2004, dnp introduced the Supernova screen range – the world’s first front projection screens to break the 15:1 contrast barrier. What’s more, our rear projection screens offer contrast ratios of well above 30:1.

Thanks to advanced contrast-enhancement technologies, dnp optical screens dramatically boost the perceived quality of your image. You get blacker blacks, more vivid colours and brighter, sharper images. In fact, scientific tests show that dnp optical screens can enhance the contrast level of a projected image by 7 times when compared to a similar image on a standard white front projection screen.
