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. 

LCOS Microdisplays offered by HOLOEYE Systems:
Microdisplay size from 0.55” to 0.72”
Resolution from 1280x768 (WXGA) to 1920x1080(HDTV)
Frame rate from 60 Hz to 180 Hz
Digital drive schemes
Monochrome and Color-Field-Sequential LCOS microdisplays
Amplitude and Phase modulating LCOS microdisplays

LCOS is highly scalable and can create very small pixels, also well suited for laser projection (since a laser is already polarized and requires the smallest possible display)
LCOS via HSI is cost effective and readily available for niche markets
HSI offers an open technology platform to allow LCOS to adapt to various applications
LCOS can modulate amplitude, polarization and phase
