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.
