摘要：
A reflective electronic display includes a front light assembly with a diffuser for enlarging the viewing cone of the display. The front light may include a substrate, a plurality of optical turning features, and a diffuser formed therebetween. The haze of the diffuser may be spatially non-uniform and switchable between two or more levels.
