Rear Projection: LCoS

LCoS is an emerging LCD technology that operates differently from other LCD displays. LCoS rear-projection TVs work by directing light through a series of polarizers (a type of light filter used to organize light waves into a single path for reflection) before being magnified and projected onto the screen.
