Abstract

The performance of liquid crystal displays and micro display projection systems is for a large part determined by the lamps and illumination optics they are using. Traditionally, gas discharge lamps are used, but light-emitting diode lamps are gradually taking over because of their attractive characteristics. We will discuss how the transfer to light-emitting diodes in the various display architectures changes the key performance parameters, remaining technical challenges, and prospects for future improvement
