About dnp rear projection

The ultimate in large screen projection

If you are looking for the ultimate in image quality and you have room for a built-in solution then look no further. Optical rear projection is for you.

 

In a rear projection systems, or large screen TV, the projector is positioned behind the screen. This means that a presenter can stand in front of the image without being blinded by the projector or casting shadows onto the presentation. And with the technical equipment hidden behind the screen, the room remains quiet, clean and tidy.

 

While conventional diffusion screens are passive, dnp optical screens are dynamic. The built-in lens system focuses and enhances the rear-projected image for optimum viewing, delivering sharp and crisp high-contrast images. Plus, it also deals with critical issues such as ambient light, reflections and difficult viewing angles.

 

This makes optical rear projection screens ideal for displaying large screen images in situations with high levels of ambient light – e.g. control rooms, conference rooms, airports and shopping malls. Optical rear projection screens are also ideal for built-in home cinema installations and they are a perfect match for modern home theater projectors.

Optical rear projection screen technology

dnp optical rear projection screens combine the focusing qualities of advanced Fresnel lenses with the distributive properties of meticulously crafted lenticular lenses. 

 

The Fresnel lens on the projector side focuses projected light at right-angles to the screen. This ensures a perfect light distribution with even screen luminance. The vertical lenticular lenses on the screen "catch" the light and distribute it across a wide viewing area.

 

Furthermore, dnp screens incorporate contrast-enhancement technologies and filters which absorb and reject ambient light.

 

As a result, dnp optical rear projection screens provide up to 4 times the brightness and clarity of conventional large screen TV. In fact, dnp rear projection screens use light so effectively that you can project large images in brightly-lit rooms - or even outdoors.

Fresnel Lens

The high precision Fresnel lens on the projector side redirects the projected light and sends it forwards at right angles to the screen. The diffusion material in the acrylic screen controls the vertical light distribution.

 

The fine pitch lenticular lenses on the front side of the screen distribute the image through a 180° horizontal viewing area. The matt surface prevents reflections from light sources in the studio environment.
