Abstract
The proper design and analysis of edge-lit backlit liquid-crystal displays (LCD) is discussed. The goal of a good display design is high transfer efficiency, defined as the visible light flux emitted by the source compared to that emitted by the display output aperture. New features in software tools such as TracePro help keep track of these goals while reducing design complexity. A good design will balance high transfer efficiency and luminance uniformity, and will minimize spectral variation across the display. The most effective design incorporates the light source, injector, lightguide, microstructure lightguide features, back reflector, and films such as diffusers or brightness-enhancement films. Microstructure feature placed on the bottom of the lightguide surface reduce the total internal reflection (TIR) while addressing luminance uniformity. A new tool called Textured RepTile allows the designer to optimize the output luminance to obtain the highest transfer efficiency.
