Technology trends of high‐pressure mercury short‐arc lamps for projection systems

Abstract— We will discuss the advantages and limitations of ac and dc lamp technology for microdisplay‐based projection systems. The performance of the lamp in terms of brilliance and thermal robustness together with the potential lamp lifetime for ac and dc lamps will be discussed. ac and dc lamp designs will be evaluated to judge their potential for future improvements in terms of usable projector lumens.
