Source : Ars technicaCold Cathode Fluorescent Lamp (CCFL) backlighting has two major inconveniences: they consume a lot of energy and manufacturing requires the use of mercury and arsenic, two poisons.
When Steve Jobs announced that Apple will be progressively abandoning this technology for LEDs even Greenpeace applauded the initiative.
Now, although LEDs do not use these metals, they contain Gallium Arsenide, which California has now placed on the list of potentially carcinogenic materials according to a publication of the International Agency for Research on Cancer (IARC).
Fortunately, there is no risk of Cancer from using a MacBook Pro. Rather, this is so that precautions for those who work in factories producing LEDs can be reenforced.
