— 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 Vcom drift inside the asymmetrical LCOS cells are presented.
