Liquid crystal on silicon (LCoS or LCOS) is a miniaturized reflective active-matrix liquid-crystal display which uses a liquid crystal layer on top of a silicon backplane. It is also referred to as a spatial light modulator. LCoS was initially developed for projection televisions but is now used for wavelength selective switching, structured illumination, near-eye displays and optical pulse shaping. By way of comparison, some LCD projectors use transmissive LCD, allowing light to pass through the liquid crystal. In a LCoS display, a CMOS chip controls the voltage on square reflective aluminium electrodes buried just below the chip surface, each controlling one pixel. Rising demand for high resolution display is expected to boost LCoS market growth. LCoS-based products offer various advantages such as higher quality and more precise results than technologies such as Liquid Crystal Display (LCD) and Digital Light Processing (DLP). The key drivers for LCoS are open technology platfo...
