A 4k projection display for D-cinema, medical imaging and simulation

Liquid crystal on silicon (LCOS) combines two very well-known technologies, namely the IC/CMOS and the liquid crystal (LC) technologies. As both of these are very mature, it is obvious that LCOS has a huge potential for very high-end applications, more than any other (projection) technology. The aim of the FORK project is the development of a LCOS microdisplay device for very diverse applications in simulation, medical imaging, control rooms and digital cinema. These applications require or benefit from very high pixel counts, high contrast ratio´s, very high light fluxes and very good colour and brightness uniformity, analog pixel addressing and high response times. A few microdisplay devices have recently been marketed for the applications mentioned above although none of these devices which meet all of these criteria.
