Wichita Business Journal - June 22, 2007 - You may have never heard of light emitting diodes, but you see them every day. LEDs are the small light bulbs in your cell phones, digital clocks and traffic lights. They are a versatile tool in electronics. Unlike ordinary bulbs, LEDs don't burn out. They never even really get hot, except in the world of advertising, where they are helping to cast a newer -- brighter -- light on how to convey a message. You can hardly drive anywhere in Wichita without seeing some kind of LED sign or billboard. Some of them have a basic, Lite-Brite appearance. Others, like the 14-by-48-foot billboard above the Starbucks on Central and Rock Road, have television quality. The electronic displays are similar to a regular billboard, except the displays may change every six to 10 seconds.
