Dell has announced that it plans have LED (light-emitting diode) backlit displays in 80 percent of its computers by 2008 and in all of them by 2010. LED displays consume 43 percent less energy for a 15 inch screen than standard CCFL (cold cathode fluorescent lamp) displays. According to the company, its LED displays will save $20 million and 220 million KWh in 2010 and 2011 combined.
In addition to being energy-efficient, LED displays also extend a notebook computer’s battery life from an average of 3 hours to 6 hours. LED displays also allow for much thinner panels.
Computer manufacturers have been slow to get on the LED bandwagon, so Dell deserves some serious credit for its announcement. Apple says it plans to get rid of CCFL displays eventually—but gives no timeline—and Hewlett-Packard sells optional LED displays on some of its computers.
