Liquid Crystal On Silicon. An imaging chip technology that has been likened to a cross between LCD and DLP. Like LCDs this uses one liquid crystal per pixel to control the light, but whereas LCD is transmissive, the light travels through the crystals, LCOS appears as a reflective chip, like DLP. LCOS is the basis for many imagers, JVC’s implementation is D-ILA and Sony’s SXRG appear to use some similar ideas – though many refinements are used.
