Display light leakage on top corners of my X1 Screen? anyone?

Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info

Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.

it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed

I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.

humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?

yup, it's there

don't see any leakage on mine...

I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?

I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess

honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...

Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.

lucky if u only seen it on top corners, mine are on all corners!

i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...

Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.

I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.

Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...

Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.

Screen malfunction : "liquid-like" spot appears under glass screen!

I've had my Legend for two days now. I've ported all apps with AppBrain, I've restored all contacts, sms/mms/call logs and I've set it up with my Google account.
Then after I plugged it from charging today:
- I noticed a "spot" in the center of the screen.
- It has a "wobbly" edge to it (caterpillar like)
- It's darker than the rest of the screen
- There are five "spots" in a line running thru it which are as light/same color as the rest of the screen (I figure these are somehow part of the touch functionality of the screen).
- When I run my finger over it, it "moves" in fluid like motion, up and down the screen. NOT sideways.
- It's visible when screen is turned on, but there is nothing visible on the or damage to the AMOLED.
What's going on here? It's off-course never been droppen, it's brand new, it's only been out of the house ONCE for a small walk...you know the drill, it's brand new.
I figure some kind of fault in the assembly of the phone, perhaps the capacative layer is loosening from the glass or the glass is touching the amoled.
I've sent mail to the store and I'm awaiting an answer. BUT, these things can be a hassle. How should I handle this? Should I use it anymore at all?
Anyone else seen this before or on their Legend? (I've dropped my Hero several times and never seen this before).
Thx

Totally agree. I had a similar problem in a Diamond2 and the "spot" went biger and biger with months.

that depends on which country you are in, if in SG, they (HTC) will sure push it as user abuse and void warranty. So All the best

I've read far and wide about AMOLED displays and suspect that this "defect" could have been caused by water seepage.
AMOLED and water do not mix well...
AMOLED and bright sunlight also do not mix well.

Black spots on screen

Yes I know there have been other posts about this but this one is a little different, or at least not one that I have seen before.
I've taken a long exposure shot of my Note II in the dark with my DSLR to show the spots on the screen when it is black. I've only noticed them with my eyes when actually trying to look for them by turning all the lights off and waiting til my eyes adjust to seeing nothing so they don't bother me at all but thought it was interesting anyway.

My galaxy s2 had that ... but my notes screen is perfect ... Blahhhhhhhhhh that sucks man it's just luck of the draw

Like I say I never notice it when actually using the phone so really not bothered by it. I prefer what I have with the really dark blacks to the LCD on my last phone which was nowhere near black.

Folks, bought my SGN2 from New Delhi and I seem to have the Black Ink mark/line on the screen. Its only visible in the dark under the certain colors, eg. Grey when you use the stock Android SMS app.
Should I get the phone checked at the service centre or is this normal as I've read that this is a Samsung AOMLED manufacturing process. There were a lot of Note & Galaxy 2 phone with it. Even the Note 2 seems to be plagued.

My S2 had that problem. I haven't noticed anything like that for my Note 2 under any lighting conditions. I've been looking by forcing gray backgrounds and using stuff like screen filter to reduce dimness. Still looks good!

Mine Note 2 has a big spot on the upper right hand side of the screen

I assume its completely normal as there are a lot of people who faced this Black spot thingy, I bought my Note 2 three days ago and yesterday I noticed a big black spot on screen, but its only visible in a completely dark environment with pitch black picture on my phone.. It doesn't affect my experience with note 2 in any way, but still we want 100% perfect screen when we pay such a huge amount. Btw I bought it from local store at Chandigarh,India and the box says made in Vietnam.
PS:- As AMOLED screens are really thin, May be some glue accumulated on the back of the screen is the reason for these spots. And it is completely normal as If it were a defect it wouldn't be on almost every screen.

i also had black dots on screen and bubbles under the glass.service center replaced the display and now the black dots relocated to different locations but bubbles are gone.
i bought from kolkata. i would suggest not to take your phone to service center as they added 15-20 scratches to back cover , 4-5 dents to metal lining on side and 3-4 scratches to new display.Samsung service center in india doesn't know how to handle cellphones.They did this to multiple people.

This is an extreme case of OCD. All amoled screens have this issue. The fact that you need to try so hard to find it is why it is consisted acceptable for what you otherwise get with an amoled screen.

Yeah, Samsung India is not up to the mark in providing customer satisfaction and as you mentioned that how they handled your device, is the reason why am just dealing with this spot issue. its still better to have those spots then these scratches and dents.
Samsung should replace the handset itself if its not more then one month old, not just the display.

Had a long vertical 'Black Line" after the 'Samsung' Logo and it went from one end to the other end. It was noticeable during the startup screen of Grand Theft Auto III and on certain colors, eg: Grey. Several other black dots were around the screen as well.
Sold it off and bought another Note2. So far it's perfect

miura, this is one of the flaws with amoled, try getting it exchanged
also, you seem to have the vertical line issue too

I had this same issue and im thinking that it might be a component that touches the screen below.

Let me ask you all a simple question, Where are your Note 2's Made? You find this information by removing the battery cover and checking on the white sticker behind your phone. Let me know, as this can suggest something.

We don't know actually what it really is, but it is considered as normal in AMOLED manufacturing criteria.
Its annoying when you see it, but it doesn't affect screen or device in any way, So, am living with it. As its only visible in dark room with pitch black or some grey shade screen.

^^^^ where is your note made in?

After removing the back cover and battery, Made by Samsung , nothing else. But on the actual Box it was printed "made In Taiwan".

[Q] [HELP] Screen burn-in problems

Guys, I have a terrible issue with my LG G2's screen. Apparently, it looks like it's gotten some annoying burn-ins, which look like white lines running across the screen. They aren't much of a problem for me, but they have got very annoying in recent time. And, it seems like they are becoming more prominent with time. Here are some pics in order to get a feel of what I'm talking about. Can it be fixed with a display tester app? Please help! This burn-ins are driving me nuts! Didn't pay so much for a flagship handset with screen issues. :crying:
By the way, these burn-ins are most evident on grey backgrounds, as shown in the screenshots with a plain grey wallpaper.

This is very strange.
I was under the impression that LCD screens could not get burn-in.
Maybe what you are experiencing is not burn in.
One of the reasons why i came to this phone because i have had the galaxy s2 with LED display and i got status bar burn in as i have noticed happens to many people with led displays. AMOLED included.

Dont quote me on this but Im pretty sure it must be the reflective foil getting too close or tearing on the back of the LCD at a pressure point. Did your phone LCD take in impacts/heavy pressure or anyoone sit on it?

No, not at all. I take great care of my device. Not once has it fallen, nor be treated with pressure on the screen. Once, my mother happened to sit on my brother's G2, however, but he didn't experience any issues whatsoever. At least no similar burn-ins as on my device.

Weird, get warranty replacement then, still sure its probably the reflective layer, but hard to say what else could cause it to warp, since you say it hasnt suffered any abnormal usage.

I have this problem as well, especially in Hangouts since it's grey in color. Not really a big deal though, as it goes away a few seconds later. Now if it sticks, then that's a problem.

Those weird lines seem to stick. But, I wouldn't want to mess with replacement units, warranty repair etc. If it gets too annoying to handle, my first approach would be the display tester app. Plus, these "burn-ins" are less prominent (almost invisible) in outdoor lighting and do not tend to appear as much (or at all) on different backgrounds than grey.

uneven screen backlight...anyone?

Hi guys,
Anyone else notice any uneven screen backlighting? I read forums on the v20, and when reading back text on white background - while scrolling down to read more text I notice dark shades on the screen. I downloaded screen test and lo and behold...dark patch on my screen! I then sent it back to LG and assured me that they replaced the screen module and tested it and all 'voltage' was normal - BUT, dark shades were still present albeit in a different spot!
Can someone here please confirm if this is a normal thing for LG screen as I realise it is LCD backlit and not OLED hence a few bleeding / inconsistency of backlight would be present. Even though I have never experienced this on ANY of my HTC's which were all LCD screens.
cheers guys! sorry for the long post!

Yes, i have it too! H910 variant. Two dark/dim spots that run horizontal from edge to edge. Can be more noticeable/annoying in landscape view than portrait actually.
Exchanged one brand new H910 for another. Same problem. Both manufactured 12/16. Havent had this on any other LG Ive owned (RS988 G5, D850 G3, P930 Nitro HD) or Moto for that matter. Pretty bummed to have this in an $830 USD device.
Edit...seems like the issue can be excaberated by different viewing angles. Also, totally anecdotal, but i looked at my display at a stoplight (wearing polarized shades) and i noticed the screen looked unaffected by the shades compared to other LCDs (cars TFT nav screen, an eIPS tablet, etc) that i have in the car. Wonder if what we are seeing is some type of side effect from a polarizing filter, or maybe lack of, used with this display/panel?
Or, maybe these things are edge-lit and LG used an uneven arrangement of emitters. Not really sure.

Good call...I do think it may be the backlight being edge lit! which could only mean (maybe) the backlight has failed at some spots or LG engineers mis-formulated where to put the lighting. it is very sad to hear that this may not be an isolated problem.
I did however sent it back for repair and the technician advice of a NEW LCD module/screen fitted. was sent back to me the same day!! WOW! BUT...same problem but it a different spot.
If this keeps going I may have to consider a new device altogether!
Then im starting to hear crackling on both earpiece and speakers....but thats a different thread!
arrgg...

I began to notice this on my v20 that I bought at the end of December, at first I thought it was just viewing angle or I messed up the screen. However my mom just got a v20 and hers' has the exact same problem in nearly the same spot. I should add that my phone is an LS997 that is completely stock. Also @D0NZ which screen test application did you use to see the problem better?

I used an app called full screen test...its free and simple. I then took a photo of it with my old htc m8 then sent it to lg for review.

The V10s have this as well. Something to do with the backlight and 2nd screen. Kind of got used to it on my V10. Was hoping that would have been addressed with the build of the V20.

I think so. On the V10 it was really noticeable when the main screen went into immersive mode and the 2nd screen went off.

this to me is a deal breaker! I read a lot on my phone, tis why I got a large screen! If this is the 'norm' for a flagship...
I pretty much think its unacceptable. They produce their own screens and cant get a flagship right? hmm...which phone to replace it with now that is available locally (for me that is down under)

So here are some pics I sent LG originally!

Looking at your grey screen, those bands/dim areas are in the exact same locations on my device (and my prior V20)! It must be inherent to this panel. You said the bands/dim locations changed after LG swapped screens/devices for you though?
Either way, it is a bummer. I'm still undecided if I should return mine as well, or just live with it. Almost every recent device has some quirk to live with it seems. I recently traded a Samsung Galaxy S7 that had a beautiful AMOLED display, but the device picked up scratches (on the display *and* body) like I've never seen before. I even took a look over at the dark side (Apple), and they seem to be catching flak for overheating and camera problems in some iPhone 7 devices. Sigh.

I have it on one corner pretty bad, is this because of the IPS screen and how the frame of the phone is pressing on it?

I think its to do with backlight distribution tbh. Ive had a number of HTC's and NONE of them had backlight distribution issues. Im now wondering IF a 3rd party screen module would be better than the original LG produced? OR...if this is an isolated issue only on some devices. My device was manufactured Nov 2016. Maybe a later produced model has better screens? Anyone with a newer produced V20 care to share?

I think its the placement of the 2nd screen backlight. Ill try to find the thread. Someone with a V10 explained it last year.

Here is the post I remember from the V10 forums that seem to make the most sense regarding backlight being uneven.
https://forum.xda-developers.com/showpost.php?p=64236798&postcount=45

Both my replacement V20 and original V20 have uneven screen backlighting (at least the replacement has a better back cover mechanism). There is a dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.

^
I think I can live with that...as in...the dim sections are on the edge of the screen. Mine was in the middle of the screen which i cannot stand!
I have sent the replaced screen NOT to LG but to the place where I bought it.
They said that the repairer that LG told me to send it to was the last on their system as 'reliable'. The store said that they will deal with the repairer and LG. I kind of hope the worst happens and they just offer me a refund or a total replacement - but I doubt that would happen!

UPDATE: so i sent it back to jb hifi, on the report, they can replicate the issue. On the repairers report - they couldnt
SO i get it back with all the 'test' that they have done on it being to manufacturer's specs.
Which i think now...was never good to begin with
Too bad i cant unsee what i can see...sux...I wonder if AMOLEDs have these issues? Anyone care to elaborate?

I have this issue with my LG V20 -- only when viewing photos - see photos -- screen has two long bright lines.
See attached photos - lines are not on the photos themselves --it is just in the backlighting -- and the lines are not there when viewing websites or if testing the screen with an test app. Please cut ans paste links to see photos - remove blank area after http -- I can't post links till I have 10 posts on this site - if any kind poster could repost so others can see them that would be great!

I have the same issue below secondary screen. Only noticeable on white background. Doesn't ruin reading books, it's there, but minor. I have dual sim variant. I'd be very upset if I paid launching price. All those things you only find out when you get the device.
