    led is only the backlight and is an option instead of ccfl

    all screens are lcd, they give you picture and "determine the shapes that will appear"

    LED superior. CCFL inferior.

    LED = brighter, better contrast and better battery life. Viewing angle is about the same.

    LED is supposed to last long, like CCFL on average can run for 6 yrs non-stop, while the LED version can run for 10yrs or so. But who is going to run them non-stop?

    It's not just running them; the age of the components affects the performance.

    I have some laptops that have been runstop for 4 years...still plugging away.

    Screen lately have better longevity; I recall back in the late 90's and early 00's, notebook displays would fade; punk out over time. That seems to be less of an issues these days, but dead pixels seems to still be a problem.

    The LED backlight does make a difference, and it more energy efficient. Dell said all their displays are going that way by 2009/2010; I'm sure it will become the standard over time, just like SATA replaced PATA.

    I consider LED backlighting to be the greatest technology advancement, for laptops, since Centrino. The screen is, by far, the most used part of the machine.

    But, of course, OLEDs will end up being a far better advancement than LED-backlit. Much better contrast ratio (resulting in a lower-brightness setting being comfortable) and the fact that dark pixels will actually consume virtually no electricity ... I'm thinking that'll be a big improvement in battery life.

    Plus we'll see better dark UIs come out as a result.

    Doesn't OLED rot?

    They're working on those kinda problems ;)

    Once it's fixed, they should last pretty long and help laptops get better battery life and also be more comfortable to view.
