You know how compact fluorescent light bulbs have been so prominent in this early stage of this green technology revolution? Well, it turns out that flat screen displays have been using fluorescents from the beginning. Obviously, incandscents wouldn't work, so thin, cold-cathode fluorescent lights were used as LCD back lights.
But here at EcoGeek we've moved so far beyond CFLs that they're starting to seem like antiques. And we were glad today when we got an e-mail from Dell saying they felt the same way.
Dell is officially switching all of the back lights in their laptop screens from fluorescents to LEDs. LEDs are more efficient, allow for higher contrast ratios and they don't contain mercury like current fluorescents do.
The shift at Dell is certainly a signal that pretty much all flat screen monitors will soon be LED lit. And hopefully that means home applications won't be too far behind.

DELL DRIVING TRANSITION TO ENERGY-EFFICIENT LED DISPLAYS
· Announces 12-Month, 100 Percent Mercury-Free Target for New Laptops
· Multi-Year Energy Savings Estimated at $20 million
ROUND ROCK, Texas and MONACO, Sept. 24, 2008 – Dell plans to transition all of its new laptop displays to light-emitting diode (LED) in the next 12 months, a major achievement in its commitment to become the ‘greenest’ technology company on the http://www.marthawashingtoninn.com/drug-generic-levitra planet.
“Our customers have made it clear that they want the greenest technology possible,” Jeff Clarke, senior vice president, Dell Product Group said during the company’s mobility summit in Monte Carlo today. “As an industry, we can shape the future of green innovation and significantly reduce the carbon footprint associated with mobile computing.

In addition to being mercury-free and highly recyclable, LED displays deliver significant energy savings compared to cold cathode fluorescent lamp (CCFL) technology. For example, Dell’s 15-inch LED displays consume an average of 43 percent less power at maximum brightness, resulting in extraordinary cost and carbon savings. The company estimates customer savings of approximately $20 million and cialis on line us 220 million kilowatt-hours in 2010 and 2011 combined, the equivalent of annual CO2 emissions resulting from energy use of more than 10,000 homes.
Dell also estimates that at least 80 percent of its total laptop volume will be delivered with LED as a standard back-lit display by the end of 2009 and 100 percent in 2010. The company’s progress in LED technology is evidenced not only by this long-term commitment but also by development efforts over the past 18 months. Dell expects the development and supply chain enablement efforts to pave the way for others in the industry to follow.
