LCOS stands for Liquid Crystal on Silicon.
LCOS is the combination of LCD (Liquid Crystal Display) and DLP (digital light processing). LCD uses liquid crystals, one for each pixel, on glass panels. Light passes through these LCD panels on the way to the lens and is modulated by the liquid crystals as it passes. Thus it is a "transmissive" technology.
This is a reflective technology that uses liquid crystals instead of individual mirrors. In LCOS, liquid crystals are applied to a reflective mirror substrate. As the liquid crystals open and close, the light is either reflected from the mirror below, or blocked. This modulates the light and creates the image. LCOS-based projectors typically use three LCOS chips to modulate light in the red, green, and blue channels.
The Advantages of LCOS:
LCOS projectors have several key advantages over other more popular technologies like the LCD and DLP. First, due partly to inherent high resolution, and partly to high fill factors (minimal space between pixels) on the chips, visible pixelation on an LCOS machine is nonexistent. Even close up the pixel structure from the LCOS is less visible than what you get with the high resolution 1280x720 DLP Mustang chip. So the resulting video image is smoother.
Second, with LCOS the pixel edges tend to be smoother compared to the sharp edges of the micro-mirrors in DLP. This gives them an analog-like response, whereas micro-mirrors add high frequencies that accentuate their digital nature. In practical terms, this gives the LCOS image a smoother, more natural look and feel, while DLP tends to impart a synthetic sharpness to the image that some would describe as harsh.
Third, LCOS and LCD projectors deliver continuous red, green and blue simultaneously onto the screen. Single-chip DLPs deliver color sequentially, alternating between red, green, and blue one color at a time. Though DLP projectors can be capable of delivering rich, well saturated colors, LCOS products tend to be more superior in this regard.
