LED backlight designs with the flow-line method

Publicated to:Optics Express. 20 (101): A62-A68 - 2012-01-02 20(101), DOI: 10.1364/OE.20.000A62

Abstract

An LED backlight has been designed using the flow-line design method. This method allows a very efficient control of the light extraction. The light is confined inside the guide by total internal reflection, being extracted only by specially calculated surfaces: the ejectors. Backlight designs presented here have a total optical efficiency of up to 80% (including Fresnel and absorption losses) with an FWHM below 30 degrees. The experimental results of the first prototype are shown. (C)2011 Optical Society of America
