LCOS (Liquid Crystal on Silicon) is a reflective microdisplay technology based on a Silicon backplane. The electronic circuits controling the liquid crystals are fabricated on a silicon chip, which is coated with a highly reflective surface. This results a very high fill factor (image is less pixilated) because the circuitry is behind the pixel (compared with transmissive LC, electronics surround the pixels) and does not create an obstruction in the light path (“screen door” effect). Using standard CMOS processes, microdisplays with extremely small pixels, high fill factor (pixel aperture ratio) and low fabrication costs can be created.
