U.S. and U.K. warplanes to get active
The low-power, high-resolution benefits of active-matrix LCDs are finding their way into the cockpits of some of the most advanced fighters and trainers. The Eagle-5 from dpiX, a Xerox New Enterprise Company is a 5-inch display that provides color tactical data, full-motion video, and high-resolution monochrome for forward-looking infrared (FLIR) imagery in the same unit. The use of active-matrix technology eliminates the "smearing" of full-motion video, a problem reportedly common with other military flat-panel displays. Planar Advance, a division of Planar Systems Inc., ruggedizes the displays for military use. The first units are being installed in the U.S. Navy's F/A-18 Hornets, Marine AV-8 Harriers, and the U.K.'s Hawk trainers.

High-brightness LCD outshines the sun
The ColorBrite LC640.480-AC1 from Planar Systems Inc. provides 900 nits brightness for sunlight readability in outdoor applications, such as kiosks, gasoline pumps, and other point-of-sale devices. The 10.4-in VGA display uses active-matrix LCD technology and has a number of features for all-weather conditions. These include an automatic brightness adjustment that measures the ambient light level and adjusts brightness and contrast for optimal image quality. Since the units are expected to operate in direct sunlight and possibly extreme temperatures, an over-temperature sensor is included.
