Front projection screens including reflective and refractive layers of differing spatial frequencies, and methods of fabricating same

摘要

Projection screens include a substrate, a reflective layer on the substrate and a refractive layer on the substrate. The reflective layer includes reflective microstructures of about 5 mum to about 500 mum in size, and arranged in a first pattern to reflect light at a first spatial frequency. The refractive layer includes refractive microstructures of about 5mum to about 500mum in size, and arranged in a second pattern that is different from the first pattern, to refract light at a second spatial frequency that is different than the first spatial frequency. Related fabrication methods also are described.
