(Liquid Crystal on Silicon) A technology used to make microdisplays for rear-projection TVs and head-mounted displays (HMDs). Each LCoS chip hosts a grayscale LCD shutter sandwiched between a cover glass and a mirror. The bottom of the cover glass is coated with indium tin oxide that holds a charge. When combined with the charges at the x-y location on the chip's matrix, it causes the liquid crystals to modulate the light for that pixel.

A Mirror Reflects Light Back
Typically used in sets of three (one each for red, green and blue), light is beamed onto the LCoS chip. For the pixels modulated to allow light to pass through, the light hits a mirror and is reflected back to a color filter. The output of the three color filters is combined and magnified to the size of the screen.

Silicon X-tal Reflective Display (SXRD) and Direct Drive Image Light Amplifier (D-ILA and HD-ILA) are proprietary LCoS technologies from Sony and JVC respectively. See rear-projection TV and head mounted display.

Liquid Crystal Microdisplays
LCoS uses LCD panels similar to LCD-based units, except that light is reflected back from a mirror behind the panel to color filters before heading to the lenses.

LCoS Chips from Aurora Systems
Also known as "imagers" and "spatial light modulators," LCoS microdisplays are typically less than an inch square, and their pixel pitch is in the 8-20 micron range.These chips have resolutions from 1024x768 to 1280x768. (Image courtesy of Aurora Systems, Inc.)
