Q Does anyone elses do this? rings on screen with light pressure - Eee Pad Transformer Q&A, Help & Troubleshooting

if I apply light pressure on back of tablet about two inches above asus logo it looks like something is pushing against the screen you get all those rings and what looks like a rainbow effect.
I noticed it when docked and moving the screen back and forth the same effect occurs.. is this just cos the unit is thin and flexes, does anyone else see this behaviour?

I tried what you did and I don't see anything, how big/noticeable is this 'rainbow effect' you're talking about on your tablet? Something doesn't seem right.

Going further if I simply press on the touch screen in that area I get the same effect somethings definitely wrong, when screen is on I get big yellow splodges from the backlight. The screen must be moving in the chassis I guess

I think you're describing the general effect of applying pressure to an LCD screen. They all do it to some extent. Unless the effect is permanent, it's nothing to worry about.

I disagree, I tried and failed to replicate what he did. Also, my tablet has the bleeding issue too, so I don't think those are directly related. (I have light spots and edge bleeding, but don't have the rainbow effect.)

Its so annoying cos its ones of the newer serial numbers and there is hardly any bleed or anything, but in normal use touching the screen in one place seems to compress something and I get rainbow and big blobs of yellowy light about 1 inch above where I touch/press or if I move screen back or forward in dock or press against back of tablet.. Lets see what asus cs say.. Might have to go for refund and defect to samsung but I don't want to

Very frustrating to say the least because if you get a good one it is superb.Cant blame you if you do jump ship but i would encourage you to give it one more shot.

iPad2 has some of the same issues, light bleed, etc and some new ones, cracking screens. It is tough to make a screen that is high res, light weight, thin, and can stand up to people poking at it all day long.

[solved] Xoom screen question

I just ditched my Notion ink Adam for the mighty Xoom. I'm glad to say I'm impressed. Now for the reason behind my post. Is it normal to see a diamond like pattern(what I suspect to be the digitizer) behind the glass.... I first noticed it while playing with the youtube app. The deep black colors gave way to what I thought was just noise from the video, but after looking at it on an angle with the screen off you can definitely see the pattern.
Is this normal? Last I remember seeing a digitizer was on my Mogul.
Sent from my PC36100 using XDA Premium App
A small moire type pattern or a large contrast difference pattern. I have seen the large pattern occasionally. It doesn't seem to interfere with actual usage.
it the screen capacitive touch sensors (dunno the technical term). i can see it on just about every touch screen except the ipad - go figure.
the 101 is a crosshatch, the nook color are dots, this xoom is a crosshatch with some kind of checker pattern.
I figured it was normal, just didn't expect it to be so profound. It has no hindering effect on user experience. I hope people don't take this and blow it out of proportion as a flaw...lol

They probably will.. lol I've seen people make issues of of something trivial like a button squeaking when you press it.. I can already picture people saying "my xoom screen is messed up"

yeah the only time you notice it will be on dark scenes/backgrounds with ambient light and holding it at a certain angle. the 101 is more predominant but it's really not a bother.
Bad LCD panel?
Hi everyone. I just bought my wifi-only model from Staples today (Sunday). I noticed a little "problem" with the LCD panel when I turned it on, but disregarded it.
While watching a movie, I noticed the issue in full force. When a movie file is playing and there is a black background, I can see "mini-panels" and it's very distracting. I don't see this on a solid black background without media playing so I'm guessing it's something with the backlight. I'm attaching a photo (glad I was able to capture it this way!).
Anyone else seeing this? I didn't look close enough at the store's display.
And so it begins...

that's the capacitive sensors. i wonder how apple hides theirs.
Ive got them too, didnt notice it on any other devices ive used but its just the capacitor mesh that moto decided to use. My glass almost seems wavy as well (like not 100% flat) so not sure what my feelings are on that yet...
my guess on the waves is that it helps curb reflections.
Yeah what you guys are seeing is definitely the digitizer. On most touch screen devices you can see the digitizer at the right angle and with bright enough light (ie sunlight seems to bring it out the most). My guess is if you test this is a lower light setting you wont see any of the digitizer.
I have also noticed the digitizer on the xoom screen relatively easily.
well, ive just noticed the waves. i usually see small waves on screens but these are warps. good thing i'm trying to pay attention to the image on screen instead of the reflection, lol.
I have seen little warps on the bottom of the screen like 1/3 or the way to the middle and 2/3 to the right side (like a couple inches off center on each side). They are also in the same relative position on the top. My guess is this is how the screen is attached? It would be great if someone could take a good look at theirs, it may take looking at the reflection of light in those spots to actually see the warp, but I would really like to know if it is just mine or it is on all of them. And BTW I see the digitizer too, but it is worse on my HTC inspire 4g.

[Q] Screen issue? Defective?

Hi all,
So I just got my Transformer this evening and am hoping and praying for no issues.
I am wondering about something when I turn on the unit however already... I cannot tell if this is normal or not.
On the lower part of the welcome screen about maybe a 1/4 way up from the bottom there seems to be a faint light bar/line that goes across from one side to the other in this area.
I cannot tell if this is part of the welcome screen or if this is a flaw. Everything as far as leaks goes and such looks great from all sides but this concerns me. If it's part of the welcome design screen then great! If not I think I obviously have a problem with the screen. I hope this is not the case.
I have attached the best image I could take with crap camera showing the line. I apologize for it not being the best quality.
If anyone can assist I'd truly appreciate it. I don't want to test it on other screens as I wanted to let my Transformer charge completely before getting into it as it states. What is a good amount of time to let it charge to get the most out of my battery?
Thanks again for all help offered.

You can't get a clear idea about light bleed with a background like that. Download a black image from the web and open it from the gallery app, that will give you an almost black screen. Light leak is most noticeable on a black screen with brightness set to max.

What about the streak of light that is going through the Android character is what I am referring to?
It's definitely not extremely blatant on this photo but you can certainly see it.

That's the background ... if there is a problem it will most likely be at the most extreme edges, it almost looks like there might be some on the bottom but that could be camera angle.
You already opened the box and took off the plastic, going past the welcome screen isn'tgoing to affect return policy or anything. Even if it did you can do a full wipe and be back to that screen in minutes.

Great thanks a lot! Yes you are right there is some at the bottom.
What you see is correct... Are there ones out there that do not have this bleeding at the bottom?
Thanks.

Tough question. Probably? I think all have it to some degree, but like my new one I have to put a blanket over my head, turn the screen all black, and turn the brightness all the way up to notice it. If you don't notice it or it doesn't bother you it is just an aesthetic problem that shouldn't ever get worse (or better). If it does and you can exchange it I would recommend doing that instead of sending it to Asus. There are plenty of horror stories about people sending it for repair.
However I would wait until you only have a week left to send it back to see if you forget about it. Some people have gone through nearly a dozen returns looking for a perfect one. I mean we deserve to get one without flaws, but sadly these screens are so prone to bleed that it seems to make some people just give up on tablets...

Yeah I can understand that. That is a great answer.
I noticed there is also noticable bleed on the left side as well near the bottom as well as the bleed noticed on the bottom all closer to the center and left.
Probably want to try out another one with there being more than just a little at the bottom. What do you think degen?
Thanks for your response.

Like I mentioned I am on my second one, although I also had a blotch in the middle of my screen. If it bothers you now there's a good chance it always will. Sadly it's a roll of the dice. However having got mine from Amazon I figured I would rather return it then just regret it. Lightbleed SHOULDN'T exist but sadly you may have to settle with it to some degree but not a lot of it. If it bugs you while warching movies, playing games, or web browsing I would try exhanging it. Make sure to try it at night if you aren't sure. That's when it will be the most noticeable.

Screen burn in or ghost image?

I noticed after my keyboard went away yesterday I saw some screen burn in. Is this normal? It also does it when I pull down the notifications bar. Is this a burn in or ghost image? Is the screen defective im not sure
I've noticed it too on my phone. when something dark is on the screen it tends to take a second or two to fade away.

So do we know if this is a hardware problem on all samsung's screens or just the skyrocket?
Same here. I thought I was going crazy because LCDs are not suppose to burn in.
Is it true that LCD aren't supposed to burn in? At my local ATT store the samsung focus phones have horrible screen burn in. And they use the super amoled screen which I think is LCD.
I bought my skyrocket literally the day it came out, and haven't had a single issue with the screen, lines or burn in, no restart issues, UCLC5 works great, and most of the other stuff people complain about.
I wonder if the later released phones had a small manufacturing flaw. when did you guys get your skyrockets?

I just got mine like two weeks ago. I wonder if certain batches are better than others. Also, It could be that you just think you don't have the issues but maybe its because you arent looking for them. Which is good don't look for them it will bug you.
It's an oLED screen, not LCD, and burn in is an issue over a long time.

Our screen is just like a plasma TV, burn in is possible if a static image is left on the screen, there is a break in period for the screen just like a plasma.
In the market get the app called display tester. It has functions to remove burn in, like a plasma TV.

The black levels...

They're not at all awesome!
I'm coming from a Galaxy Nexus (Amoled display) which has close to perfect black levels, and a ASUS Transformer (IPS display) which while it wasn't to brag about, it was better than the Galaxy Note 10.1's screen.
I was really looking forward to the PLS display on the Note, I heard nothing but great reviews on the tech, but this is really bad.
I mean the blacks aren't even even, its more purple than black.
Is this normal for PLS?
Is anyone else having this issue?
Were there any mods that can be done that fix this issue on other Samsung PLS tablets?
I don't see anything wrong with the black level but I haven't tried using the tablet in the dark yet. Don't compare AMOLED with LCD. LCD will always have ****ty black because of the backlight. The only LCD type I know that has decent black level is CPVA but it's not used in tablets and it's still far from perfect. Asus Transformer TF101 has much worse black level (I have both). Are you talkin about some newer Transformer? Or maybe your brightness is set too high?
Also keep in mind that a lot of websites don't use pure black fonts.
Try turning the display mode up to vibrant and reducing the the brightness.

if he's referring to the infinity, it's got a very annoying dynamic contrast. the screen dims and brightens as the screen changes, but it's not very discreet at doing so. my main reason for rooting the tf700 was to disable this stupid feature.
I'm sure I'm missing aomething, but I have a decent sum tied up in a plasma and HT equipment to get blacks close to right at home, so am always amazed to see people moan about black levela on $500 mobile device. I'm still amazed I can watch pretty hifh quality movies and even live tv on a mobile device like this, and just cant imagime being worried about blacks unless just atrocious. Am I expecting too little froma device like this?
I was referring to the tf101, but I went to best buy again and compared it to the demo model and realized mine was completely off.
So I TiB backed it up, flash that bad boy back to stock and exchanged it. This new screen is way better.
Although the viewing angles aren't amazing its still an awesome tablet.
Yeah, the viewing angles are the only disappointment for me.

Some are pretty bad like the iPad3 where if you're not directly front and center there is significant brightness fall off.

How much of this is to be expected?
I have a noticeable amount , of course I only noticed it when in a dark room against black backgrounds.. but it makes me wonder if I should demand another unit from amazon.

Mine has it too. bottom right side and bottom. Only visible when watching full screen video that's letterboxed. Doesn't bother me though.
I notice it gets worse when I flex the tablet by holding it in landscape by the bottom left corner so I kind of wonder if in part it is more predominant on that corner for my tablet because that's the primary way that I hold the tablet. It's not like I can flex it the other way to get rid of the bleeding completely though so I don't know if I can reverse it. If memory serves, out of the box I already had some bleed anyhow. This is my second Note Pro and the first one had bleed on the bottom as well.
I'm sure you'll get responses from some who have no light bleed, some of which actually do but it doesn't bother them and some who really do not have any bleed. It's up to you I guess if it is worth the effort and waiting to try to get a perfect one. For me it simply is not . .
Thanks.. can any one post any pictures of their tablet?
I have attached mine under full brightness, total darkness and black background.. it is slightly exaggerated in some phots as it depends on what angle you see the screen
Sent from my SM-P900 using XDA Free mobile app
I have the same hot spot on the bottom edge to the right of center. On the right bottom corner I have some that is less pronounced.
The only 'sort of' light bleed I have is from the two softkeys when they light up.... Other than that, none whatsoever. (Can't take a photo as I can't imagine they'll shut down the entire train to give me some darkness...)
