An active-matrix system offers sharper, cleaner, higher contract and deeper color images. Overall, this type of system offers faster response speeds and is suitable for multimedia, animation and video. The price is now as affordable as the older passive type LCD projection systems. Active-matrix systems use either Amorphous Silicon (A-Si) or Poly Silicon (P-Si) in the liquid crystal formulations; the newer P-Si material offers brighter images.
