LCOS (Liquid-Crystal-on-Silicon) Microdisplays

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.

LCOS microdisplay technology can compete and in some cases even outperform all other display technologies with respect to resolution， size， ease of use， quality and price. HOLOEYE Systems´s OEM LCOS microdisplay service includes basic implementation assistance and performance specification for specialized applications. HOLOEYE Systems offers modification of driver parameters for customer specific requirements resulting in low-cost intelligent driver boards ready for mass production. This positions HOLOEYE Systems to be a key-supplier accross numerous markets and to be the very first company to market a “complete solution” to the end-user， whether they are in the defense， medical or aerospace industry. Even the highly cost-sensitive automotive industry is able to develop HUD systems based on high resolution HDTV LCOS microdisplay technology.
