The inorganic LED was once a competitive technology, as developed by companies like Planar, Luxell, and Sharp. "The solution for direct-view displays in military implementations today is almost exclusively LCD," Pinnel says. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., and industry groups created this consortium in 1993 to boost domestic manufacturing of flat-panel displays.

Kaiser Electro-Optics and Vision Systems International make both displays for prime contractor Lockheed Martin.

Displays designed to operate outdoors must be visible by day but nearly invisible at night displays that individual soldiers carry must be lightweight and flexible and displays for command-and-control rooms must have great size and resolution. Once they have done all that, displays must boast top performance in a huge variety of conditions. So what is so special about LCDs? Military users demand displays that are inexpensive yet tough enough to stand up to conditions like wrench-drop and boot-kick tests.Īt the same time, however, they have to be more than physically tough displays must meet demanding military standards, shield against emissions of electromagnetic radiation, protect power-supply lines, manage thermal emissions, pare weight down, and keep power efficiency up.
