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.

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.

I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.

This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

[Q] Light Bleed? Common issue? Faulty?

Hi,
I have just received my Asus TF today, and I absolutely love it!
However I have just noticed that in the middle of the screen @ the very bottom the light is slightly bleeding out (ie there is a lighter spot on the black bar).
Its just right above the docking point.
Is this a common issue / design, or is mine faulty?
Sorry, its probably a completely stupid question, but I just want to figure out if I should be asking for a new one....

It's a common issue, you're not alone.
Some of us have returned TF's with light bleed, while others accept it.

If you just have one section at the bottom, keep it. Mine had four different areas of bleed.

I have light bleeding but only noticeable when showing pure full screen black picture in a dark room. So its not really a big deal for me ( I guess nothing is perfect). However, I wonder if others have worse.

I have some light bleed at the bottom of my screen in 3 different areas. Its not too bad and i can only see it on a black screen. Its better ecer since i put the sceen on auto brightness

this problem will exist with LG ips screen. :O

Got my replacement from BestBuy today, Original had one bad light bleed and 3 smaller ones. Also had a dead pixel in the middle of the screen.
New one has small light bleed in lower corner, hardly noticeable and no dead pixels.
Now I just need to pick a ROM to put on ;-)

No. No it will not. LG IPS panels do not even have backlights; not inherently, anyway.
I hate when people blame light bleed on IPS. It's not the IPS technology, it's the poor quality edge-lighting

Yes, that's probably true. Asus might be responsible for the backlight, or they may have bought it from yet another third party, but it's probably LG's.

Mine has very small ribboning of light at the bottom of the screen, would have never noticed in normal use. I checked my Ipad that I have had for a year and its exactly the same and in the same place, never noticed till I looked for it. Possibly all tablets have LB to some extent if its not noticible in every day use its only a problem if it bothers you looking at a black screen in a dark room

Not all tablets have lightbleed.
Most do, though, because of the form factor basically requiring edge-lit backlights, which are very tempermental

I just received mine yesterday & don't seem to have any light bleed. That is unless I don't know what I am looking for.
My only real issue seems to be with the power button. I have to push it 2 or 3 time for my transformer to wake up.

I have the same issue, 2 spots at the top of the screen. I don't think I ever see it though unless the display is entirely black or at least very dark. If it were much worse I'd consider getting a replacement, however from what I've read on the subject it doesn't seem to get (significantly) worse over time under normal conditions, however excess strain may worsen the effect. Thankfully the TF101 seems pretty solid so I don't think its going to be much of an issue.

Mine has it in about three or four places too, I don't really care about it though.

Sadly I just noticed two spots in the middle of my screen that are white. I do not think it is light bleed but I have already issued a RMA with NCIX on this.
I noticed that it is an issue on Amazon as well....according to this review.
http://www.amazon.com/review/R21G1E2O7DUE83/ref=cm_srch_res_rtr_alt_1
Dammit.
Ah well. Will RMA it and if that fails will get a refund and get a Acer Iconia instead.

yellow screen?

Is this normal or do I have a faulty unit?
Screen looks very yellow compared to my other phones.

What is the other phone? Go to settings -> display -> color mode and set color to normal, that will normalize it a little. It's set on vibrant by default. Regardless of that setting though, the screen on this phone is a "warm" one compared to others. The phone on the left is "cold" and bluish in comparison. Warm screens are a little more yellow/red, cold are blue. If the other phone is AMOLED there's your reason, but even if it's LCD, it's just tuned a bit differently. You should know that the phone on the left isn't producing a perfect white either, just a kind of white you're used to. Personally I prefer a warm screen, I find colder screens harder on my eyes.
TLDR- it's working as intended.

Unless you screwed with some settings no that isn't normal. If my whites were that yellow I'd return it. While an LCD might never be as white or black as an amoled it shouldn't look like 20 year old yellow paper either. WIth LCDs if you lower the brightness the screen will become more colored but nothing like that. You can also go compare it to some phones at the store that have LCD's and get an idea if its out of whack.

I spoke to two different support people at motorola ...one said it was normal for this phone as the screen was optimized for gaming?? .....the other said it was not normal and I should return it.
I tried using the app 'screen adjuster' to boost the blue light and it did indeed make it look white rather than yellow so it seems to be a color temperature setting so I'm still not sure wether changing the phone would make any difference and I can't compare in stores because they don't have them yet.
p.s. the other phone is an LG G2 which is LCD

Mine seems to have a little yellow at low screen brightness but it doesn't seem as bad as in your photo. I probably would not have noticed if not for this thread. Is your screen brightness low? Mine gets more white as the brightness goes up.

If it bothers you you can go through the return process and see if another one is different. My phone looks pretty much the same next to my Galaxy Note n-7000. That's AMOLED, but AMOLED or not, screens can be bluish. For perspective, here's what white looks like for reference. Neither of the phones are producing white. One is bluish, one is yellowish. Do you notice it when you're not comparing phone screens? After a few minutes of looking at the screen, going from app to app or looking at pictures, do white things register as white?

I noticed it had a very warm color temp immediately I turned it on, and then got my other phones to compare ....it does bother me yes ...it's like having a TV with a yellowish screen ....I'm pretty sure it can be fixed with a software update and is not a hardware problem which is why I'm not sure if returning the phone would accomplish anything unless I see some other pures to compare

This is mine. I think ambient light may affect it. It looked more yellow when I was in a dark room. This is in a well lit area.

Mine is warmer color from 50% to 0%, Higher values and its very white. Didn't even notice it till I saw this post and well, it can't be unseen lol. I keep my display around 10-20% usually on the low side however at night in bed it doesn't look warm at all.

A few display questions

Hi @all
is it normal to have a perfectly white display when looking straight at it and to have a slight reddish veil while tilting it? And is it normal that Amoled Cinema and Amoled Photo Mode are a lot more reddish than adaptive mode?
I am on my third Galaxy S8 now. My first one had a perfect display, even when tilting it had the standard blueish color of the Amoled Displays. Had to send it back because of a hardware issue.
My second and third one have the above mentioned "problems".
How is it on your device? I'm already thinking of returning even this one... i want a perfect display for the price I am paying.
Thanks for your reply.

@Duskfall89 mine has that red veil issue as well but not enough to make me go nuts. I once had 1+1 and yellow band issue drove me nuts. Nevertheless, i think you can just set the red to the lowest on the RGB settings and it will go away. Im more worried about the battery haha

It's not an issue of being standard on oled displays. The blue tint is to produce a "vivid" look that catches the eye better.
Cinema and photo are suppose to have a warmer tint to match real life viewing. (because in real life, things have a warm tint) from the sun, and standard lighting.

So is it normal that cinema and photo mode are more "reddish" than standard adaptive mode? I never tried those modes on my old S7 so I don't have any comparison.

@Duskfall89 i know how you feel. i can also verify that mine has a red veil when switching from cinema/photo/adaptive. Regardless, i think i can live with it. After going through the forums, many s8s are plagued with this issue and i got mine on Monday mind you! Others have mentioned that they have swapped around 3-4 units with most experiencing similar redness. If you're not satisfied, there are also who have swapped till they got the least red display unit but that would also run the risk having other parts that come faulty.. alas, people are never satisfied. I once swapped 3 msoft surfaces.

Yes, it's a lottery I guess...
I think I will stick with it, it really doesn't bother me too much, it's more about the fact that i know how my first S8 looked.
Amazon won't replace it anymore because it's the third phone I'd send back and so they want to check their entire stock. They offered me a complete cashback if I return it but then I would be without a phone. I could give it back, take my cash and then buy another one (which is now much cheaper than the price I paid at launch) but I am tired of setting up phones now

Yessir. They use a warm base as opposed to a cool base. If you really want to learn more about it Google TV color calibration and it will go into detail about why they use a "cool" blue tint for floor and selling and how true natural colors are more "warm" reddish
Then I recommend calibrating your TV and after a day of adjusting, you'll never want to go back.
Also, blue filter in the Phone settings will add a warm tint at night to help your eyes

@Acoustichayes good info !!! i guess i wont be so worried! but i guess the only issues here is that my reddish areas are focused at the top of the display and is not uniform across.

I had the same case but cannot really consider it as an issue as sometimes, i cannot barely see it. It's just the way it is. Also, you might wanna check out wider color gamut. i think that we're just used to the "blueish" as it looks natural but samsung uses deep red this time.

Hi, what do you mean with "had" the same case? did you get rid of it?
I got used to it now and it really isn't an issue but I'd prefer the "blueish" tint as my first S8 had that. Sadly it had the home button bug so I returned it.

Ok then it's the same as mine I could be make it more white if I'd play around with the colors but even then, while tilting the reddish veil still remains. Less noticeable but it's still there. So I decided to leave it as it was out of the box. At leats my home button now seems to work properly :laugh::laugh:
