[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.

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] Light Bleed?

I've seen some of you have said there is some 'bleeding of light' what does that mean actually? Are there holes in the casing or is it something with the screen? And how bad is it?
Edited to add: Despite the troll, a few people here have reported this problem first hand - however it appears to be small, so hopefully they got a rotten apple.

Having replaced my own LCD backlight, I can speak to it.
Basically the LED lamp sits on the very bottom of the tablet illuminating the tablet from the back (hence backlit), the light is supposed to be contained but sometimes the lamp housing may contain gaps and light will leak through those gaps. They appear as light flares across the above layers.
If you google Ipad 2 light leaks and view Images, you can see a great deal of reports with sample images of the symptom.
I'm not quite sure why companies don't just employ a rubber gasket or flap around the lamp housing to get a good light seal.

There was a comment on one of the android forums.
I noticed it when I first switched on my device, but it was late at night in a very dark room, and brightness was on full. I have brightness set to auto now, and I have never noticed this again.
I am very intolerant of defects such as this, so if I am not seeing it, it's fair to say there isn't a problem. Of course that's just my opinion, but I really don't think it is an issue.
Hold on a moment .......OK, I've just gone and stood in a dark room, and brought up the Gallery App, because it has a dark border. No backlight bleed obvious until I turned the brightness up to maximum, at which point there was a vague semi-circle of backlight just to the right of the keyboard dock. Turning the brightness down to a sensible level solved the problem.
Hope this reassures you. I should perhaps point out that I have no affiliation with Asus, or Google, and no vested interested in device sales.

It's pretty rare I think. I've only read it on a couple of occasions and as far as I know it's the only physical issue with the tablet. Everyone keeps raving about it's build quality. So, if there is any light leak in mine (when I eventually get it) I'm swapping it. Just another reason to try it in the store

The very first thread here, where people were asking for this forum to be made, there were a few people who said theirs had bleed (and a few others said the sound was uneven in playback, one side very loud the other low)
I haven't seen much, so perhaps its only a few unlucky people.

It was two people as they quoted 'has anyone' and 'i heard that there was' in other words the first person might have had it, but hasn't said anything since, the other person has heard a 'rumour'

No, spare me your rolleyes crap. It was people saying: My device has this problem. And some saying I'm returning it.
I've been reading a ton of sites about this device, and may have gotten confused about which site i read it on, but clearly there is no mistake when people say they have the problem, so don't accuse people of lying.
It certainly is mentioned here http://android.modaco.com/content/asus-eee-pad-transformer-transformer-modaco-com/336683/eee-pad-transformers-owners-thread-14-04-2011-first-post-updated/
"I had started to noticed light on my screen that shouldn't be there. This obviously is a backlight bleeding problem. ... the manager then took a look in the dark and he noticed it and said it was a fault with the screen and I can get a replacement."
http://www.avforums.com/forums/14430336-post46.html
"Screen. Some light bleed unfortunately (this is also being reported by other users on XDA forums/Modaco etc) - not a deal breaker, but it is there.. admittedly only noticable when using at night... Still great images though. "
(So he's probably not returning it)

That's the way led technology works, but lcd (and i think ips) uses backlights.

I have a little bit of light bleed about 1.5" up on the right hand side of the screen... It's about the size of a 5p coin.
I'm not going to worry about getting anything done about it I don't think. I only notice in in the settings screen, and I'm rarely in there. When I'm in portrait mode, I just see it as a 'glow' on the taskbar.

Ah yes, you're right. Was thinking Flouro. In any case, light is leaking reflecting off small gaps from the edges and into the upper layers.
Have you ever tried to completely seal out all light out of a room? It is insanely difficult and amazing how much gets through.

No I haven't I generally don't blank out all light and watch stuff that way so I guess i'm ok (incidentally I hear that is bad for the eyes, watching tv in a totally dark room, but that's another talk)

Typicaly there are two light sources - at the bottom and at the top of the screen (or on the left and on the right - my LCD monitor has it that way). Sometimes there is only one source - on the bottom mostly.
I'm not sure about this but as far as I know LED backlight works the same way - it's only at the top or bottom in most displays. Some better LCD TVs with LED backlight have more LEDs behind the screen - but it's pricy to do so I doubt tablets will have it that way.

I have a reasonable amount of light bleed on my Transformer. Areas on the horizontal and vertical near the home button.
In addition, a couple of spots on the right hand side vertical.
No major drama, called Comet and they are sending me a replacement, though not until next Thursday when they predict they will have more stock, though given what I have been reading today on various sites, that date could slip a little. Doesn't matter though, my replacement request is logged and will happen when it happens.
On the down side, by the time I get a replacement I will have spent ages getting it just how I want it.
On the up side, I get to have all the fun of setting it up again.
On a side note, having cancelled a preorder for a Xoom through PCWorld and bought the Transformer, I finally got to play with the Xoom on the shelf today.
Definitely made the right decision.
The Transformer just feels better made, and despite the fact that the Xoom has excellent viewing angles, the screen is not a patch on the Transformer, oh, and did I mention the small fact of 100 quid!

The reason I started to asks about this is because I'm a bit skittish about light bleed, having once had a monitor and the store just thinking i was nuts "there is nothing wrong with this monitor its just you" - thanks a lot! Humpf.

Q Does anyone elses do this? rings on screen with light pressure

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

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.

Backlight bleed galaxy note pro

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.
Sent from my SM-P900 using XDA Free mobile app

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...)

[Q] Screen

Hello.
I reccently bought a NVIDIA Shield Tablet, and after 2 days i had it replaced becase the screen kind of had a "brownish" color tone on one of the bezels. The new one they gave me does not have that problem but the screen is different. When turned off you can see kind of a squared patern on it, and when on you can see that patern on some viewing angles. Is this possible?
Hope to get a quick awnser so i can present this complaint on the seller.

I'm pretty sure you're talking about the digitizer matrix. Is it really visible under bright light at about a 45°angle. Lots of little horizontal striations as well reflecting off the glass?
