    Hi everyone, a new user here from the UK


    I got my iPad 2 on launch last week and noticed the backlight bleed on the first power on!

    So I went back to the apple store on Monday and got a replacement, and guess what? It was twice as bad as my original :mad:

    I have spoken to the apple store and they have put my name down for a new iPad and said they will ring me when it's ready to collect


    Out of interest I wanted to know if the backlight bleed is actually bad for the LCD? Does it actually affect the LCD or is it just cosmetic?

    Thanks for looking

    Backlight bleed is from the glue/polymer used to adhere the glass touch screens. They are backlit LED as an FYI.

    The theory is a mass implementation problem, where the glue hasn't dried yet due to high demand for the device.

    IMHO I don't think it can possible hurt the touch screen. Think of the problem like a bubble in the touch screen covers people use. It really just bleeds when dark...as color beats out the yellow hue.

    Glad they are resolving the problem.

    Peace,

    Does that mean that the LCD won't deteriorate over time because of the backlight bleed?

    Correct. The backlight is only "bleeding" because the glass and LCD are not sealed completely. They do not have to be completely sealed either... but they should be sealed to prevent dust from getting between the glass and LCD (this looks annoying when that happens)

    Within a matter of days backlight bleed will ruin your LCD, destroy the battery life, melt the CPU, steal your girlfriend, and murder your dog. :eek:

    It will not damage the screen almost all screens suffer from some degree of backlight bleed.

    It seems like all iPad 2's or most of them have some sort of backlight bleed. Mine has backlight bleeding but it's not so bad so and I don't really mind it. I thought I'lll keep the current one as the replacement could be worse.

    Yellow splotches is the glue backlight bleed is more to do with internal stress from the adhesive sponge strip they stuck the lcd bezel to the glass with.

    Im 100% certain its pushing and colapsing the bezel around the lcd deforming the edge of the panel makeing the backlight glow through, much like if you pushed the edge of an uncoverd lcd panel it goes funny!

    All apple needs to do is thin down the gasket or lay it further back problem solved the screen are perfect its just apple way of mounting them thats wrong!
