In revealing a timeline to abolish the use of toxic chemicals in Apple products, company chief executive Steve Jobs on Wednesday confirmed that the first Macs to sport LED-backlit displays will begin turning up later this year. In an open letter to customers and shareholders on plans for a greener Apple, Jobs revealed the Cupertino-based company plans to reduce and eventually eliminate the use of mercury by transitioning to LED backlighting for all displays when technically and economically feasible. "We plan to introduce our first Macs with LED backlight technology in 2007," he wrote. "Our ability to completely eliminate fluorescent lamps in all of our displays depends on how fast the LCD industry can transition to LED backlighting for larger displays."
