Flexible displays are an attractive alternative to existing liquid crystal display (LCD) models because they would be lighter and more durable, consume less power, and could ultimately be rolled up and stuffed in a pocket between uses. The technology needed to make such displays already exists. It is based on arraying pixels of individual red, green, and blue LEDs on top of electronic circuitry fabricated on flexible plastic substrates. A number of laboratories in the U.S. have already made experimental versions of such flexible displays.
The key challenge, says Eric Forsythe of Army Research Laboratory, is to improve the size, weight, and energy efficiency of these experimental displays and to find a design that can be easily manufactured. In Baltimore, Forsythe will discuss the latest research on organic LEDs and the U.S. Army's progress toward pilot-scale production of flexible displays with improved efficiency. Currently they have a small experimental display of 320 x 240 pixel resolution on a flexible material known as polyethylene naphthalate. He estimates that within a couple of years, a more manufacture-friendly model of a PDA-like flexible display will exist.

WORLD'S HIGHEST-RESOLUTION COMMERCIAL SATELLITE
Since the early 1960s, super powerful spy satellites have been the stuff of the military and intelligence communities. Now two U.S. companies have launched commercial imaging satellites that offer the same sort of space-based images of the Earth to the public. One of these companies, GeoEye of Dulles, Va., launched a multi-million dollar satellite last year, and it's the highest-resolution commercial imaging satellite in the world.
