Patterned volume diffuser elements |
摘要 |
The present invention provides a method for manufacturing an optical diffuser element comprising: a) inserting striping shims in at least one flow passage of a multi-manifold extrusion die; b) extruding a first layer of polymer with light scattering particles through the flow passage with the striping shim to create linear domains of varying diffusion; c) extruding a second layer of polymer with less diffusion than the linear domains of varying diffusion through the manifold without a striping shim; and d) extruding the first and second layers of polymer into a dual roller nip with microstructure engravings in at least one roller. |
