An ultra-high resolution projection display system based on
reflective light valves (LV) with 2560x2048 pixels is being
developed.
The main applications are graphic workstation displays (end-user
Barco) and head-up displays (HUD) (end-user Sextant).
Combining a submicron CMOS technology for self-scanning active matrix addressing with a reflective nematic liquid crystal (LC) technology, the LV can be realized in existing ASIC (Alcatel Microelectronics) and LC (Thomson-LCD) facilities, without major investments.
All necessary design and back-end processing (Imec) and LC
(Stuttgart) skills are present in the consortium.
15 µm pixels yield small 38x31 mm Light Valves, a requirement in
light, compact, cost-effective optical projection systems.
Barco has proven that the development of an AMLCD technology
for the targeted professional high-end display market can become
an economic success and must develop higher resolution display
systems to secure its position as a world leader in this market.
Sextant is European leader in electronics units for airplanes.
The availability of the targeted LV would reduce weight and
volume and improve the potential of the increasingly important
HUD-based landing systems.
Other potential application area’s are microdisplays for personal viewing applications and virtual reality headsets.
