    Apple confirms LED displays in Macs during 2007
    http://www.tuaw.com/2007/05/02/apple...s-during-2007/

    Can I be the first to say...w00t!


    Arsenic and mercury are industry standard materials used in liquid crystal displays (LCDs). Arsenic is added during the manufacturing of the high performance glass used in LCDs to prevent the formation of defects, and the fluorescent lamps used to illuminate LCDs contain minute amounts of mercury. Apple is on track to introduce our first displays using arsenic-free glass in 2007. A small number of high performance integrated circuits (ICs) will continue to contain a minute amount of arsenic as an element of the semiconductor substrate.

    To eliminate mercury in our displays, we need to transition from fluorescent lamps to light-emitting diodes (LEDs) to illuminate the displays. Fortunately, all iPod displays already use LEDs for illumination, and therefore contain no mercury. We plan to introduce our first Macs with LED backlight technology in 2007. 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.

    Apple plans to completely eliminate the use of arsenic in all of its displays by the end of 2008.

    Apple plans to reduce and eventually eliminate the use of mercury by transitioning to LED backlighting for all displays when technically and economically feasible.

    Perhaps new cinema displays... (hope!)

    Or iMacs.
    Or MacBook Pros.
    Or MacBooks.
    Etc.

    yeah i read this article, sounds good.

    But, are LED displays superior? In what ways?

    can somebody explain the difference between LCD and LED? i know what they stand for...but will impact will the swtich on the look, feel, and functionality of apple's products?

    They will still be LCD displays, but with LED backlights. The current LCD's use a form of fluorescent lighting. Best thing about LED's is more than double the lifespan of these fluorescent lights. They're also capable of much higher contrast ratio's, brighter colors, deeper blacks, whiter whites... all around a better quality and more reliable improvement over the current displays.

    ok thanks...so i guess thats a good thing...is it likely for apple to raise/lower their prices because of this?

    It is definitely a much more expensive technology. It's pretty common in a lot of smaller tech devices. Like it says in the article the Ipod... but also the PSP, I think a few PDA's. Also, if you look into high-end flashlights almost all of them use Cree and XRE brand LED's (yes, flashlights can be another expensive hobby). These flashlights also have considerably longer run times with much less battery consumption. Problem is it's still not that mainstream in larger applications like TV's and computer monitors. I only know of a few higher end pc laptops that use LED's (Sony's T series for example).

    LED backlights will hopefully be more consistent, also cooler.

    Does this mean lower likelihood of dead pixels? Or is that not connected?

    mmm don't quote me on this, but I think the screen's are still LCD they are just lit differently... In my head a dead pixel isn't a lighting issue. but what do i know? im just making an educated guess.

    Nope, the pixels are on the etched glass which the backlight shines through.
