Light bleed

So my first Transformer had minor light bleed along one edge of the screen. If I were to gently twist the tablet the bleed would fluctuate. I returned it and found that I had the only Transformer in my area so I could not get a replacement. I ended up ordering online last night.
My question is: Do all it these things have minor light bleed? If not, what are the chances my next one will have it? Or better yet the chances of me finding a remedy?
Can a few of you comment on your experiences with your own tablets please? The way I checked for it was to cover the camera sensor and take a picture. Turn the brightness all the way up and go into a dark room to look at that all black picture I just took in fullscreen mode.

My first two have had more-than-minor light bleed. I should have my third on Monday. If that one has light bleed I'll start to consider giving up on the TF.

All of them have more or less light bleed I think. Mine also have some. You can see it at the bootscreen with the asus logo.

light bleed on ips screens are very common..

I have gone through 3 of them and they all had some light bleed. I don't believe anyone that says they don't have any. They just haven't maxed out brightness, put on a black wallpaper, and gone to a completely dark room.

i have a very minor light bleed- not enough to even worry.
You can check by using the nook book app and seting a book to night read mode.
Did not want to worry about sending it out to take a chance on getting another with minor light bleed or even worse light bleed. as well i had not other probs with it so why chance it.
That doesn't mean anyone else's bleed is not worse...so it is a case by case. choice.
good luck.

I guarantee you your next TF will have some light bleed. Whether it is better or worse, is a different story.

Thank you for all of the replies. I may consider the galaxy 10.1

It is not the fact that it is an IPS screen, but the fact that it is Edge-lit to keep it thin/cheap.

Very much so. Guys...seriously stop whining about the light bleeding. It is not that important. 99% of them do this no matter what tablet you use. So just deal with it and use your new toy.

I don't have any light bleed on my tf. I'm in the UK. I must be lucky !

it really does depend on the amount of bleed though. The one I had was very severe on the bottom (in landscape). It didn't have to be dark at all to see it.

Screen burn in issue? Anyone?

Hi, I am planning of getting one of this beast. After reading on the internet about possible amoled screen burn in after using it. Could somebody share his/her experience regarding this? Is burn in screen real problem or small problem with this device? Thanks.

Never heard of screen burn in issues with amoled screens. I've had the original Galaxy S for over two years and have had no issues.

I have very, very faint screen burn in at the bottom of my 7.7 where the status bar is. Can only really notice if I'm looking for it on a white screen, but more obvious on a red screen. I believe the only reason it happened is because I took it out in the sun with me one day and put brightness up to 100% for like 90 min while browsing/reading because before that my screen was flawless. I'd say if you can keep it at low brightness you should be fine. If you're rooted I'd get a hide bar app. In contrary to all this though, my Note II has no burn in whatsoever and I leave that thing on auto brightness.

Thanks for the heads up man!

My Tab is an ex demo unit and had some massive image burn in due to it being left on while on display with the screen overlay still on the unit, so i had the big O and the smaller icons burnt into the screen, i only really noticed them when viewing solid lighter back grounds, and as i have used the tablet more for the purpose it was meant to be used for rather than sitting looking pretty on display the image burn has all but disappeared, can only really pick up traces of the burn if a really look hard enough

Here is link for tab 7.7 screen issues.

It has been already discussed before, and my question is has Samsung fixed the issue yet? Most of them say is a manufacture defect. Or maybe it just Amoled technology at infancy.

Light bleeding in my Nexus 5?

Hello everyone, i got my nexus 5 a few days ago. And i noticed some light bleeding, is this considered "acceptable" light bleeding for the N5? Im thinking that if i rma it, i might get one with worse light bleeding and maybe other issues too. Do all N5 have this issue? Or mine is not that noticeable to go for rma?

It would be very difficult to get a nexus 5 without lightbleed of varying degrees. Its a common trait of LCD technology
You can only ask yourself if it is acceptable. To me it is. You would find it almost impossible to get one without bleed. That said, you may get one with less but then by the same token, what does it really matter? If you wanted the screen to be dark in a dark room, LCD could never achieve that without an LED backlight system.

I think it's fine and not worth the RMA unless you just have to have that perfect device.

Depends how noticeable it is to you under normal usage conditions. Generally we don't use our phones in the dark with max brightness, but if it's bothering you in day to day usage then it might be worth trying a new one.

Not horrible as my RMA's Nexus 5 lol

Comes with the territory. If you feel black should be real black on your phone, get one with an amoled display type. But that technology comes with its own disadvantages like burning in pixels.
You'll have to decide for yourself what's most important to you.

We have our own "image persistence" issues with lcd too

I had the screen bleed issue on my Gnex as well, even though it is AMOLED. Haven't noticed it really on the N5 though.

You cannot have backlight bleeding with an amoled display: they don't have a backlight.

Well I don't know what to tell ya because it did have it. The whole screen when black would have a glow to it. I don't know if you could technically call it light bleed but it looked like one of the pictures in this thread.

I think if the bleed just slight in the minor region.. accept it and enjoy your phone unless it somewhat major defect..
Trying hard to find a tiny bit of defect on this Nexus 5 beat the purpose of buying the awesome phone or we called it the developer phone..

Personally I never have my screen on full brightness unless its super sunny out. So I don't ever really see the bleed. However. Whatbi see in your pictures is two corners bleeding. I only have one corner bleeding. Back when I repaired phones I got this a lot with the HTC amaze. There is a 4 corner rule. If you get bleed on all for corners. Send it in. And I mean bleed. Not fade.

Yes, there and where the volume rocker is.

Top left corner here as well, not going to RMA. It wouldn't most likely change anything; bleeds are more like a feature.

[Q] Nexus 5 question about greys and blacks

Hey there. I noticed that two of my friends with Nexus 5s have a different looking screen compared to mine. Specifically I notice this when I pull down the notification shade and instead of showing a dark black, theirs show a washed out grey. I really want to know what is going on here because I need to return my phone for a couple issues, phone calls cutting in and out, I believe on of the speakers is blown, and the volume toggle indicator wont show itself moving up and down sometimes. I am concerned though, because I really really dont want to get a phone with the washed out greys again like I had with the Nexus 4. My Nexus 5 is NOT rooted and neither are the two phones which my friends own(the ones with the washed out grey as opposed to the dark black).
Anyways, thanks for your time.
I hope to get this answered shortly.

One of the speakers? There's only one
LCD has backlight. Brighter screen, greyer blacks

There are different variables of screen, we discovered this when franco made his kernel colour tunable as people were making profiles that would give perfect 2.2 gamma for some yet be miles out all over the show for others
Sent from my Nexus 5 using Tapatalk

The majority (all?) of Nexus 5 screens appear to be considerably more yellow then they were originally. Just about every person who's had their device replacement side by side with their original one have agreed the new one has yellowed whites in comparison. This could cause duller looking colours and grayish blacks.
Does it go away as the "glue dries"? Perhaps. Most likely upon losing the original model for comparison their eyes will slowly adjust to the warmer colour temperature eventually leading to the claim that the yellowness is gone, but having no original screen to compare.
That's just my opinion on the situation though and of course I could be wrong, but it's the main reason I won't RMA for a replacement device. 7000k (original) colour temp is already plenty warm for my liking.

Light Bleeding

I've decided to start a new thread to gain some focus on this issue.
It is common on the U11 according to some posts.
I've just noticed after the recent update, maybe it was there from the beginning, that this device has a lot of light bleed around the sides when using always-on feature. Some parts of the edges of the device has greater light bleed than other sections.
It's quite noticeable and adds more light to the room at night. If only the time was showing it would be perfect. This is what I thought was there before the upgrade. However I believe that any light bleeding is a hardware thing not a software thing.
This could be a reason why it drains the battery so much.
The light bleeding isn't noticeable during the day as far as I have checked.
Maybe I should return this device but not sure if HTC will agree.

According to some early buyer, U11+ shows the light bleeding only from the bottom right corner of the display.
Also it should be barely noticeable: if your unit has "lot of light bleed around the sides" maybe it has a faulty or not properly assembled display...or maybe you are exaggerating things!

Can you please show a picture of this issue?

In darkness, the light bleed is visible, and expected on an LCD because you can not light up just the pixels (the date and notification floating window) which you want to show on an LCD . The whole screen has to be lit up with minimal brightness.
In normal lighting, its not visible at all because the brightness on U11+ can go down quite a bit and blacks are blacker than I have seen on an LCD.

See attached image.
Not sure what's acceptable with light bleeding by HTC's standards or most mobile manufacturers.

Ouch! That really looks bad.
I was eyeing this phone, and can't decide between it and the LG V30. Both seem to be a lottery with the displays unfortunately...

Asia model , its very minimal on my phone. Have to stand in a dark room to see the bleed in the right hand corner

Mine is direct from Taiwan.
Yes, the bleed is only noticeable using the always-on feature.
I could swear I didn't notice it before the recent update. But it's got to be a hardware thing.

LCD Panel + Backlight = visible light on black screen. No surprises here tbh lol

Exactly!! To all the HTC detractors making this a huge issue, show me an LCD screen which does not have it.
Here is another nugget: the non-uniform light bleed shown in the photo above is because of special algorithm followed by always on display software. If you just do a full screen black (use the Full Screen Test from play store), you will see a uniform backlighting, which is the best I have seen on an LCD. U11+ display has no defects in my opinion.
HTC should not have even tried AOD on an LCD screen.

I have the HTC 10. The black on HTC U11+ is blacker than the black on HTC 10 i.e. the backlight is even lower on U11+ than 10. I tested using the Full Screen Test I mentioned above. I would like to mention again that non-uniform light bleed is only an issue with always-on-display, and not with the screen in general. And its the non-uniformity of backlight that makes it seem like an issue.

Thanks for all the feedback.
I'm very happy with the U11+.
I just selected the option to turn the always-on feature when I move the device, so it's very liveable.
HTC has always been my favourite manufacturer for the last 13+years. The HD2 one of the best years ago.

Ouch, this light bleed seems harsh. Although it should be expected given the screen's technology.

It's not a default. Devsk explained it well, I wouldn't worry it
Even my Moto X Pure LCD screen has bleed, but it is only visible in total darkness on a black screen. Doesn't bother me in the least.
PS Anyone who is curious can download the Backlight Bleed Test app from the Playstore to view how much bleed your particular LCD screen has.

People who think this is normal for LCD screens, let me stop you right there! The HTC U11+ has blacks nearly as black as LED screens, even at night. There was no light bleed when I received this device. I held it next to the S8 Plus, and both had almost the same black values. It's amazing.
After a week however, I suddenly had an extreme light bleed, 0,5cm around all edges, like some sort of weird snow theme. Luckily it faded within an hour. Now it's normal again, except for the down right corner. That's only noticable when the screen is black, and it shows the time. It's barely noticable though.
This incident led me to believe it's anything but normal. The seller told me it's alright to exchange my device for a new one, so I hope it's not an issue with all devices. :fingers-crossed:
You'd think it's an hardware issue, but what are the possibilties the software influenced the backlight? Any thoughts?

UPDATE:
Just had a software update, and the light bleed is gone now. Even in the down right corner. Is this a coincidence, or do you think it might have been a software problem?
