LCoS Projector

LCoS combines aspects from both LCD and DLP technologies. Just like in LCD projectors, LCoS also uses three colored chips at its heart, although the light doesn’t pass through them, but is reflected just like in DLP – not by micromirrors covering the chips, but by the liquid crystals on their surface. As they operate in high resolution (1365x1024 pixels SXGA), LCoS are very expensive – and also heavier than LCD and DLP counterparts. Because of that, they are more used in home theaters than in multimedia presentation.

Model example: Sony VPL-VW40
