JVC has a TV technology they call D-ILA. What is it?
D-ILA (Direct-Drive Image Light Amplifier) is a JVC proprietary name for its LCOS (liquid-crystal-on-silicon) technology. LCOS is used in rear- and front-projection TVs. JVC and Hughes have been developing image-light-amplification for a long time. There are other similar LCOS technologies like Sony’s SXRD. LCOS sets use three spatial light modulators (“chips”) for the simultaneous display of the red-green-blue primary colors. Using three chips is an improvement over the mass-market DLP sets which use only one chip. One-chip projectors may exhibit a bothersome “rainbow effect”, caused in part by the spinning color wheel which is used to provide a color picture. The pixels on LCOS are also more tightly packed together than on most LCD and DLP chips – this reduces the visibility of the inter-pixel grid or “screen door” effect.
