Dell to Use Mercury-Free LEDs in all Laptops

ROUND ROCK, Texas --  [Editor's note: This is an updated version that clarifies the LED component of Dell's new laptops.]

Within the next two years, the computer maker will switch the back lights of all laptop screens to energy-efficient and mercury-free LEDs, a move the company says will lead to significant energy savings.

The first line of laptops will ship on December 15 of this year, and the remaining will be transitioned over the course of the coming months.

In making the announcement, Dell explained that not only will the products contain less toxic materials and thus be easier to recyle, but they will be more energy efficient, saving along the lines of 40 percent or more energy. Dell estimates that its customers will save around $10 million in energy bills by 2010.

This announcement is the latest in Dell's ongoing goal to be the world's greenest computer company. Dell has been steadily improving the efficiency of its hardware, it has worked with customers to boost energy efficiency in IT operations, and has led the way in global takeback and recycing of its products.

LCD display! The LED is the backlight

There's a language error in the first paragraph. The display will still be an LCD (liquid crystal display). The difference is that Dell will be using LEDs (light-emitting diode) as the backlight, instead of a mercury-containing CFL (compact fluorescent lamp). There are other advantages to LEDs also -- they offer a broader color gamut, so the image looks better. The tradeoff is that LEDs are more expensive and require trickier optics to use as backlights on large screens. Apparently Dell has decided that the cost within 2 years will become acceptable, and that the optics for small laptop screens will be manageable. (You probably won't see LEDs on large desktop monitors or large-screen LCD TVs for a while yet, except in certain high-end models).

Thanks for your comment ...

Thank you for bringing this to our attention. We made the change, as you can see above. You also make some good points on the viability of LEDs. Much appreciated!

Best,
