Abstract
Microstructured optical films, assemblies of films including at least one microstructured optical film, and (e.g. illuminated) display devices including a single microstructured optical film or assembly.
Claims25
An optical film comprised of a light transmissible polymeric material having a microstructured surface wherein the film is a substantially non-polarizing film having a single sheet relative gain of at least 1.78.
An assembly comprising a first microstructured optical film proximate a non-structured reflective polarizing film wherein the assembly of the first film and polarizing film has a relative gain of at least 2.59.
An assembly comprising a first substantially non-polarizing microstructured optical film proximate a second substantially non-polarizing microstructured optical film wherein the assembly of the first and second films has a relative gain of at least 2.80.
