Abstract

Described herein are articles and methods for improving illumination and light propagation in transparent materials. In particular, the articles and methods described are useful in the design of light guide plates used in electronics devices, such as televisions and monitors. Light guiding is done via the incorporation of series of holes in the light guide to control and direct light within the structure.
