Paper Abstract

Backlight displays using edge lit light guides are found in many applications, including cell phones and compute lap tops. The light guide extractor pattern is adjusted to provide the desired spatial distribution across the display. The extractor pattern optimization can be performed using Monte Carlo simulations. Multiple examples are discussed. Examples include backlights with multiple LEDs, a rod luminaire, a key pad illuminator, and a non-uniformly shaped light guide.
