Abstract

We investigate the optimal driving conditions of high power light emitting diodes (LED) in a four liquid crystal on silicon (LCOS) micro display projection architecture, taking lifetime issues of the LEDs into account. This architecture is an extension of a two LCOS panel approach. The possible light output is compared with other LCOS architectures as a function of relevant LCOS specifications. © 2007 Elsevier B.V.
