FUTURE FOR LEDS

THE PAST DECADE HAS BEEN A DRAMATIC IMPROVEMENT IN THE EFFICIENCY AND RELIABILITY OF VISIBLE-LIGHT-EMITTING DIODES. THE MAJOR PROBLEMS LIMITING THE PERFORMANCE OF THESE DEVICES HAVE BEEN MASTERED AND, AS A RESULT, LARGE-SCALE MANUFACTURING OF DIODES SUITABLE FOR A VARIETY OF APPLICATIONS HAS BECOME POSSIBLE. THEY WILL INCREASINGLY REPLACE OTHER TYPES OF SMALL DISPLAY ELEMENTS IN THE COMING YEARS AS COSTS DECREASE FURTHER. IN ADDITION, LEDS WILL BE USED IN AREAS WHERE OTHER DEVICES ARE IMPRACTICAL BECAUSE OF EXCESSIVE POWER DISSIPATION, BULKINESS, OR INADEQUATE LIFE. AT PRESENT, DIODES THAT EMIT RED LIGHT ARE THE MOST WIDELY USED. BUT NEWER MATERIALS, SUCH AS FOR GREEN EMISSION, FOR YELLOW, AND FOR BLUE, ARE BEING DEVELOPED AND WILL BECOME MORE AND MORE IMPORTANT AS THE MATERIALS PROBLEMS LIMITING THEIR REPRODUCIBILITY ARE OVERCOME. /AUTHOR/
