The system can include an anamorphic light guide that comprises a light receiving portion, a light diverting portion, and a light output portion. The light receiving portion receives light having an area illuminating a first aspect ratio and the output light portion outputs light having an area illuminating a second aspect ratio, the second aspect ratio greater than the first aspect ratio by at least an order of magnitude. The light input face is substantially perpendicular to light output face. The etendue of the light is substantially preserved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Anamorphic light guide","description":"A backlight system for a display is described.
