How does it work?

LCoS works much like DLP, only using Liquid Crystal instead of the little mirrors that DLP uses to build the image. This makes it capable of much larger resolutions than LCD and Plasma.

Who’s been promoting it?

Why am I only just hearing about this?

While LCoS actually works out to be more economical when manufacturing TVs, there’s a catch. It’s an expensive technology to get right, and a lot of money has already been sunk for it. Still, we should see some more commercial
