Invited Paper:: LCOS microdisplay technology for advanced applications

Some technology aspects of LCOS microdisplays that are important for their deployment in advanced projection applications are discussed. The selection of the liquid-crystal parameters of the vertically aligned system as a function of the requirements ( response speed, contrast, etc.) is addressed; a three-dimensional simulation engine to evaluate fringe-field effects between pixels is described, allowing the fine-tuning of the LCOS design with respect to the optical output. Finally, some observations on the nature of the so-called V-com drift inside the asymmetrical LCOS cells are presented.
