EU Framework 5 Project LCOS4LCOS
Partners:
Thomson (F), Merck (G), Thales LCD (F), ATMEL (F), IMEC (B), UCL
(GB)
Aims:
To design a low cost projection TV display including an innovative
high illumination optical engine based on a single Liquid Crystal
on Silicon (LCOS) chip.
By combining the director modelling, optical modelling and a commercial
ray tracing simulation package the optical properties of the whole
illumination, projection and optical engine system can be predicted.
