I've seen some of you have said there is some 'bleeding of light' what does that mean actually? Are there holes in the casing or is it something with the screen? And how bad is it?

Edited to add: Despite the troll, a few people here have reported this problem first hand - however it appears to be small, so hopefully they got a rotten apple.

Having replaced my own LCD backlight, I can speak to it.

Basically the LED lamp sits on the very bottom of the tablet illuminating the tablet from the back (hence backlit), the light is supposed to be contained but sometimes the lamp housing may contain gaps and light will leak through those gaps. They appear as light flares across the above layers.

If you google Ipad 2 light leaks and view Images, you can see a great deal of reports with sample images of the symptom.

I'm not quite sure why companies don't just employ a rubber gasket or flap around the lamp housing to get a good light seal.

There was a comment on one of the android forums.
I noticed it when I first switched on my device, but it was late at night in a very dark room, and brightness was on full. I have brightness set to auto now, and I have never noticed this again.

I am very intolerant of defects such as this, so if I am not seeing it, it's fair to say there isn't a problem. Of course that's just my opinion, but I really don't think it is an issue.

Hold on a moment .......OK, I've just gone and stood in a dark room, and brought up the Gallery App, because it has a dark border. No backlight bleed obvious until I turned the brightness up to maximum, at which point there was a vague semi-circle of backlight just to the right of the keyboard dock. Turning the brightness down to a sensible level solved the problem.

Hope this reassures you. I should perhaps point out that I have no affiliation with Asus, or Google, and no vested interested in device sales.

It's pretty rare I think. I've only read it on a couple of occasions and as far as I know it's the only physical issue with the tablet. Everyone keeps raving about it's build quality. So, if there is any light leak in mine (when I eventually get it) I'm swapping it. Just another reason to try it in the store

I'm afraid I don't understand that - what LED lamp (singular)? I thought whole panel was made up of tons of small "lamps" lighting up?

Hope there isn't a lot of that on the transformer

The very first thread here, where people were asking for this forum to be made, there were a few people who said theirs had bleed (and a few others said the sound was uneven in playback, one side very loud the other low)
I haven't seen much, so perhaps its only a few unlucky people.

It was two people as they quoted 'has anyone' and 'i heard that there was' in other words the first person might have had it, but hasn't said anything since, the other person has heard a 'rumour'

I'm seeing a connection here between 'tablets' and 'tabloid' newspapers.

No, spare me your rolleyes crap. It was people saying: My device has this problem. And some saying I'm returning it.

I've been reading a ton of sites about this device, and may have gotten confused about which site i read it on, but clearly there is no mistake when people say they have the problem, so don't accuse people of lying.

It certainly is mentioned here http://android.modaco.com/content/as...-post-updated/

"I had started to noticed light on my screen that shouldn't be there. This obviously is a backlight bleeding problem. ... the manager then took a look in the dark and he noticed it and said it was a fault with the screen and I can get a replacement."


http://www.avforums.com/forums/14430336-post46.html

"Screen. Some light bleed unfortunately (this is also being reported by other users on XDA forums/Modaco etc) - not a deal breaker, but it is there.. admittedly only noticable when using at night... Still great images though. "

(So he's probably not returning it)

No, in other words: You probably make up stuff all the time and think everybody else does. Stop that.

That's the way led technology works, but lcd (and i think ips) uses backlights.
