    I read in this forum how an LED backlight is prefered over the CCFL backlight. Is this true? Why does Levovo recommend the CCFL backlight?


    15.4 WXGA TFT, w/ LED Backlight [subtract $49.50]
    15.4" WSXGA+ TFT, w/ CCFL Backlight [Lenovo recommended]

    The first one has a 1280x800 resolution. The second, 1680x1050.

    There's nothing magical about LEDs. They're brighter and offer some more battery life, but image quality is not necessarily any better.

    I believe old 4:3 panels were crappier than 'new' 16:10 CCFL powered panels, they have better contrast and more brilliant, even though LED ones offer superior battery life.

    I would pick up a high res CCFL against a low res (WXGA) LED one.

    Here are some things to consider:

    Size: LED monitors are thinner than CCFL

    Brightness: LED has that glossy finish, making it more susceptible to glare but offers more vibrant colors

    Lifespan- LED again wins in this category. CCFL output decreases over time. End of life is when they are half as bright. LEDs are solid state devices, so that problem wont occur

    Power: LED draws more power

    Cost: LED is more expensive

    You can read all of this at this website.

    That would depend on the panel. The FlexViews on the ThinkPads A31 to T60 were better than anything being offered on a mainstream notebook nowadays.

    The resolution on the CCFL is why its recommended. 1280x800 in anything bigger then 12in is painful for multi-taskers.

    How long is that "over time"? I have a CCFL WSXGA+ that's getting to 3 years old and I can barely see whats on the screen in a fluorescent lamp lit office. Its much better under older yellow lamps that I have at home. Working on battery is even worse - no viewing angles.

    Viewing angle isn't dependent on backlight. It is dependent on the panel type and pretty much all notebooks use TN panels, which have the worst viewing angles.

    LED / CCFL backlight has nothing to do with the glossy/matte surface.

    i'm also highly skeptical of that article, in particluar the power consumption bit. according to what i know (and wikipedia http://en.wikipedia.org/wiki/LED-backlit_LCD_television ), led uses less power (up to 40%, says wikipedia). it is literally the first time i've read that led uses more power...
