Backlight bleeding

My MacBook pro 2011 has a decent amount of backlight bleed on the bottom but I was told that is normal.....

Um, my HP dv7 has absolutely no bleedthrough at all. So it is not normal for computers to do that. (Keep in mind that HP and Apple products are manufactured/built by the same company. Obviously they are designed by different people.)

But I did have to replace the LCD panel (toddler-related damage) and I know that HP uses both clips AND glue to hold their screens together. I cannot speak for Apple.

You may want to try the rub trick.

Guys and gals, don't settle for less than perfect, we all paid good money for these devices! :)

But 'perfect' with LED backlighting is very rarely obtainable. When you have to display a totally black screen with the brightness turned up to 100% to notice light bleed, you don't have a problem. That picture one MR Page One, is a nice screen. That minimal light bleed would NEVER be noticed during normal use.

PC World stated in their review that the HP dv7 had a dull, dim screen, which will have an effect on light bleed. Are you displaying a solid black image in a dark room with your brightness turned up to 100% ? That's what most of these people are doing. Most people's light bleed isn't an issue during normal operation.

While I see your point, and agree I am very thankful its not as bad as some of the ones others have posted, it's just that for $700 I would like something a little better. Love it in every other way, it's just distracting when watching movies etc. I am kinda picky though :) I appreciate the reality check. Hopefully everyone can get this figured out! Best of luck.

I didn't mean to come across rude, sorry! I understand the 700.00 part but Apple will probably say within spec's. By the way yours looks like my iPhone did with a yellowish tint. After a few days of use it went away. Glue issue, post if it clears up.

Yep. But that does raise another question. If your macbook has light bleed is that with reflective or matte screen? My dv7 doesn't have a matte screen to grab light (in fact, there is nothing between the LCD panel itself and the outside world. The cover is built into the panel.)

As for PC World's review, that review was from two years ago. Mine does not resemble that one at all (other than the 17" screen hence the "7" in dv7; HP will use a model number until eternity. Their 17" entertainment PC running Windows 12 with 16TB RAM will still be called dv7. )

Focus sucks and this is 100% brightness in a completely dark bathroom. I haven't tried watching a movie but that's next as that will be the most likely scenario where this will be an issue. I don't think mine is worth returning unless Apple admits some major fault and does mass replacements, which IMO would be overkill for something like this. It's a mass-produced LED display, and my 24" Samsung monitor has it much, much worse.

I'm sure some people have true defects but I don't think mine is one. No yellow tint on white pages, either.

I see the bleeding on the top image, left hand side, about 1/3 up from the bottom. Not major but it would bother me on something that expensive.

I don't know if the first iPad had these problems, but I think the iPhne 4 did when it first came out. This is very annoying though.

Wow, yours is pretty bad - the vid really shows it.

This all started with the iPod Touch (certain production weeks had bad screens where the blacks were really a sort of grey). Then again with iPhone 16Gig, then I think again with iPhone 3G's.

Seems like Apple is not having very good QC with their touchscreen devices...

Is anyones iPad "perfect?"
Click to expand...

Yes, my brand new first generation iPad has a pretty much perfect screen. Faultless black levels all along the edge. Best Buy had no replacements when I returned my bleeding 64GB black wifi iPad 2 this morning, so I picked up a first gen instead and it looks fantastic. Also cost $100 less, so that lessens the blow.
 
Funny!

:)

Honestly, one of the reasons I had picked up a 64 GB model last night was to fill it up with movies. So I would have been seeing that bleed a lot.

I posted a little while ago that mine didn't have problems, I was wrong. It is bleeding through, but it's minimal and I could ONLY see it in an almost pitch black room with the brightness at 100%. I'll never be using the brightness at 100%, so for me it's not an issue.

Your screen is absolutely fine. Any flaws that you do see it nit picking beyond belief.

It's making me nervous too. If it's just like, light blotchy like on laptops/lcd tvs, it's not a big deal. but if it's like a really focused spot like some people have than that will get REALLY annoying really quick when looking at anything dark.

Here's a comparison video with the original iPad. I think it's an common IPS issue and probably a non-issue for most people.

If I had the iPad 2 that you showed in the video I would be happy. My iPad 2 screen has roughly 10 light leaks all around the screen. It looks horrible while watching movies and while using the cam or anything with a darker background.My stock apps crash all the time and it took 6 hours to charge my iPad from 1% to 100%.

My god that nearly looks perfect. I would love to have that screen. Hopefully I can get one like that on my exchange unit.

Wow you got lucky...I can see it yeah but it's way better than 90% of the rest of the people with this problem including me :p Ours are *really* bad.

That video is total rubbish. The guy says that you wont see a dark image on the screen when you're using the iPad normally -- yeah OK. If you download an HD movie in 16:9 AR from the iTunes you're going to see two big black dark images throughout the _entire_movie_ on the edges of the screen! He also claims that this is a common problem with IPS. Again, rubbish. I have two Dell U2410 UltraSharp IPS 24" displays -- neither of which has any light bleeding at all (they are professional displays yeah, but they didn't cost as much as the iPad 2 :p) -- and also my iPad 1 has no (yes NO) bleeding whatsoever.

Mine has more, but that's what was prominent on the camera. And like I said, angle matters. Certainly that doesn't mean all units are within spec.
 
I don't know why backlight bleed is so variable, but it is NOT inherent with IPS or LED technologies.

I have seen a couple of corner bleeds on cheaper no-name brands like a five year old Westinghouse 32" CCFL LCD TV and a Proscan 42" LED LCD TV.

But I don't have any backlight bleed with my NEC IPS 23" CCFL monitor, my iPod Touch 4th Gen (LED LCD), Samsung Netbook 10.1" TN LED LCD, HP dv6 15" TN CCFL LCD, or my Sony 32" IPS CCFL LCD TV.

It is normal on an IPS screen for the color black to turn dark purple when looking at odd angles in the dark. But the light coming through on the sides is NOT normal.

I agree completely. I have a samsung LED 40" 120hz tv and like I said two U2410 Dell H-IPS ultrasharps -- no bleeding at all... plus I have no bleeding on my first gen ipad!

Of course, an AMOLED wouldn't have this problem.
Click to expand...

AMOLED has other problems...imho IPS is the best display technology currently. Major problems with AMOLED are image burn in (especially blue pixels), sunlight viewing (only mfg who solved this problem is Samsung and they're not selling them to anyone else), and overall display lifetime. There's also that PenTile matrix crap -- although Samsung seems to have fixed that too I think...but again, they're not selling their "Super" AMOLED or Super Amoled 2 \ Plus displays to anyone else. My last phone had AMOLED, and I prefer IPS. Just my opinion though -- the one thing I really liked about the SuperAMOLED was the color vibrance -- it was insane...a bit too insane but I still liked it.

I'd say all you guys are not seeing at it properly, all devices bleed - including every other competitor devices. Dont drag Steve on stage from his medical absence to explain you this simple "Apple" fact. Dont see at edges till apple works on bumpers for edges :).

Let's see pic's of it. I would like to see how bad it really is.
 
Same on mine. Bottom of the screen, to the right of the home button. 16GB black. I'd exchange it, but they're in such short supply. I'll take it in in a couple weeks once the fervor has died down.
