looking for a large TV, the usual suspects that are on the top of most
people’s wish lists are plasmas, rear-projection DLPs, rear-projection
LCDs and the ever-growing but still very expensive large direct view
LCD displays. One technology that is sometimes overlooked is LCOS,
which stands for Liquid Crystal On Silicon. Essentially a hybrid of LCD
and DLP, LCOS uses liquid crystals that are applied to a reflective
mirror; the light is modulated by the liquid crystals as it passes
through them. DLP, on the other hand, uses a reflective technology that
bounces the light either towards or away from the light by tilting the
mirrors. JVC uses a type of LCOS called D-ILA, which stands for
Direct-Drive Image Light Amplifier, in their rear projection TVs and
stand-alone projectors. D-ILA uses three chips, one for red, one for
green and one for blue, unlike DLP’s spinning color wheel.
