Engineers at Planar Systems Inc. of Beaverton, Ore., are announcing their ability to produce the so-called MicroBrite family of active-matrix electroluminescent miniature displays for military, industrial, and consumer applications. The high-resolution displays measure 0.75 inch diagonally, are 2 millimeters thick, and weigh less than 3 grams. The solid-state MicroBrite displays, which can produce the same virtual image of a large-screen TV, are inherently rugged, have long lifecycles, and operate over wide temperature ranges, Planar officials say. Company designers developed these displays originally under supervision of the U.S. Defense Advanced Research Projects Agency. By the end of 1997 Planar will offer monochrome and color displays in VGA resolution of 640 by 640 pixels. - J.K.
