Abstract
This disclosure provides systems, methods and apparatus for a front illumination device with metalized light-turning features. In one aspect, an illumination device includes a light guide having light-turning features that include recesses formed on the light guide and that extend down into the light guide. The recesses may be coated with a material where the material also forms an auxiliary structure outside of the recesses on the light guide. The auxiliary structure may be conductive and may form, for example, an electrode.
