Abstract
This disclosure provides systems, methods and apparatus for forming light-guiding layers including embossed light-turning features. In one aspect, an aluminized polymer layer can be embossed onto a light-transmissive layer having a high index of refraction to form the light-guiding layer. In another aspect, the light-guiding layers may be formed using a mold that has positive relief features and features which mechanically separate a portion of an embossed reflective layer from surrounding portions of the embossed reflective layer to form light-turning features.
