Taken from "Design News," 1-8-90, Page 24.
"Durham, NC -- Cree Research, Inc. has built the missing link in
full-color light-emitting diode (LED) displays -- a pure blue emission
diode. Three families of silicon carbide blue LEDs use a low power
peak wavelength to produce the purer blue. LEDs are semiconductors
that produce visible when connected to an electrical power source.
List prices for Cree's die are $1.47 in 100,000-unit quantities --
that's about a tenth the cost of the competetion, Cree says. By
combining the new blue with red and green LED chips, designers can
produce any color light in the visible spectrum, including white. For
more information, call Cree at (919)-361-5709."
