dnp Cross Prism
50” - 80”
The dnp Cross Prism Screen sets new standards for
the image quality of multi-screen installations. It offers
unsurpassed contrast, excellent viewing ­angles and
allows design of near-seamless display walls with bright,
speckle-free images.

The dnp Cross Prism Screen solves two quality issues in
design of modern control room displays: seam size and image
speckle from single lens projectors.
Made from an acrylic styrene copolymer material the dnp
Cross Prism Screen is highly resistant to unstable projection
environments. While acrylic based screens expand/retract with
room humidity, the Cross Prism Screen retains its dimensions.
This allows design of cubes and display walls with almost
invisible seams.
Moreover, the Cross Prism Screen incorporates t­echnology
that eliminates “speckle” – the small bright spots in the image
which are a well-known problem with single lens engines. The
result is a smooth and clean image – even at close view.
The advanced lens design includes a Fresnel lens and two
crossed prism lenticular structures with contrast enhancing
dnp Black Stripe technology. As a result, the screen is
extremely tolerant to ambient light. The front surface of the
screen features a non glare, hard coat surface that protects
the screen and avoids specular reflections from light sources
such as windows and room lightning.

. Screen profile (horizontal section)
The ultra fine pitch Fresnel lens focuses the projected image and distributes it through a 4-layer lenticular lens.
This element enhances the image for optimum viewing by distributing light vertically and horizontally. The black
stripes on the crossed prism structures effectively absorb ambient light. Finally the image is transported through
a carrier layer that is protected by scratch-proof, non glare surface.
