dnp rear projection screens 

Optical rear projection from dnp is a projection concept which provides up to 4 times brighter and sharper images than conventional front or rear projection screens. In fact, optical screens use light so effectively that they allow you to project large images in brightly lit rooms - and even outdoors.

The technique used with these large optical screens is "rear projection". This means that the projector is placed behind the screen, shooting straight forward towards the audience. The optical screen controls the light path and distributes bright, sharp images into a predefined viewing zone.
