Abstract: A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three- Dimensional Micro structures) with large reliefs exceeding 1 μm and being as large as 100 μm. The Micro structures can be either deterministic (such as micro prisms), or random (such as diffusers), the first obtained by copying an original super master, and latter obtained by copying a laser speckle pattern. The master process entails copying a super master into the form of the micro structure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization. Therefore, the invention comprises three alternative processes: one, hybrid (adhesive on acrylic), and two monolithic ones. In the PALM (hybrid) process, an epoxy is wet-coated on film substrates such as polycarbonate (PC), polyester (PET), (PE), or other flexible material. The adhesive, in liquid form, is applied to the substrate by a self-metered coating sub-process. In the present invention, the adhesive is used for forming the micro structure pattern. The micro structure pattern is replicated from a master roll or image drum onto a coating roll.

Abstract: The present disclosure reveals a reflective, front-projection screen designed to faithfully and accurately display the images from state-of-the-art (SOTA) and next- generation 2D and 3D motion-picture projectors, such as those found in large-capacity public movie theaters, home theaters, offices, and for use with portable projection systems for consumer and commercial applications. In particular it discloses cinema- size light shaping 3D projection screens with front-surface microstructures and horizontal viewing angles in the range of 90 to 120 degrees.
