[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

I'm afraid I don't understand that - what LED lamp (singular)? I thought whole panel was made up of tons of small "lamps" lighting up?

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'
I'm seeing a connection here between 'tablets' and 'tabloid' newspapers.

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.

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.

G2x wow!!

there is probably another thread about the same stuff but i just gotta say it i just got the LG G2x last friday all i can say is wow i love this phone super fast far more faster then my epic 4g and evo 4g im in love with my phone its awesome

there are some people here claiming that tmobile should be receiving new units that supposedly has no screen bleed...hopefully they are right and i can go exchange my unit for one without screen bleed.

What is a screen bleed, and how do you know if your screen has it? I can't see any problem on mine. Does it only occur when you have certain wallpaper?

I would like to hear the answer to this too, what does screen bleed look like? I've tried pure black and pure white wallpaper looking for whatever you guys are talking about.
Sometimes I wonder if I'm the only person who has a near-perfect G2X that doesn't misbehave in all the ways people here talk about. The only way I can get my phone to spontaneously boot or any other signs of instability is to overclock to 1500 and run Mandrobench five times in a row, by which time it is red hot. If good G2X's are so hard to come by maybe I should auction mine off.

Go into a room with all the lights off. Start up a video or something in which the background is all black (and pause before it starts playing). The screen bleed will appear at the top left or right corners of the device. If your screen does bleed you will be able to see some light penetrate through lighting up the top corners. If you do have it you can't miss it as it quite pronounced.

When you have a all black wallpaper look into all the corners of your screen (usually top right and left corners) if you have back bleed you will notice where the light bleeds out onto the black wallpaper. It doesn't effect me to much because I don't use dark wallpapers I like to show off my colors and nice screen but hopefully your unit doesn't have this issue enjoy

[Q] Screen Quality

I just got a G2X yesterday and it has backlight arterial flow. It's not obvious looking head on but it doesn't take much of an angle to see light peeking around the edges. I've heard this is a "known issue" but would anyone else return their phone for a replacement? How likely is it that I'll have the same problem with the next one? I've had the vibrant since release and I've gotten used to the contrast and color of the amoled screen but I don't think I'm just being spoiled. For $500 I feel light bleed should not be an issue. Black uniformity? Ehhhh not quite as much but still... Anyone care to comment?

It is very likely you would get another phone with same issue.
LG uses a screen texhnology that has that bleed.

Youre new around these parts aren't ya? Lol
Its a very well know issue. Look around this forum and you'll find countless references to it. It comes down to what is acceptable for you? Some people have returned and exchanged multiple times to correct it. For me, its barely noticeable and only on a black screen in a dark room so it doesn't bother me.
Look around the forum and then judge for yourself if you can live with the problem.

I'll probably try a return and if it happens again, I'll just deal and think about an upgrade later on. Like I said I'm used to the samsung screens so this problem is all new to me. Overall the build of the phone feels sturdier than the vibrant. I also like that web browsing is much smoother.

I can deal with that. I don't want reboots and a over heating phone. The screen problems are minimal on my phone.

Have you done a complete hard reset/restore of the phone? Factory data reset?
It significantly cooled down my phone after doing it. Never had a reboot on the phone afterwards, but prior to that I only had one reboot, so I don't think I had a problem
I had installed a bunch of task killer/ battery saver apps on the phone, and the combo screwed things up software wise.....have not touched any task killers since.

I try that when I get a my new memory card.
Thanks.

If mininmal light bleed is your only problem just keep it. Most likely the replacement will also have it. Even with light bleed the screen looked better than the sensations...

red flashing infared light.....anyone else notice?

While making/receiving/in call....there is a flashing red light. Did anyone else notice this besides me? It's towards the bottom left of the FC.
Is there a purpose for this?

Haha yeah dude that's the proximity sensor that cuts the screen off when you put it to your face. I noticed that last night. Pretty funny that you can actually see it.

Take any camera and film your different remotes while you press their buttons and the camera will upconvert the infrared spectrum into the visible spectrum.
But I have never heard of any human able to actually see the infrared spectrum although there exists animals that can detect it.

Indeed. My first thought when I saw it was "why am I seeing infrared light....what the hell?????". But anyways, no biggie. Can't really see it unless you're looking for it in the dark or something. Certainly isn't an issue or problem.

i too can see it
does that mean we are superhuman ?

OK I thought REALLY hard and was able to levitate the One S. I'll see what else we can do with it. I think the next step is using it as a heat ray weapon.

Yeah, make a call in a dark room, you'll see it. But its def. the prox. sensor.

smart butts!!!
Lol, sorry I didn't mean to put inferred, I put inferred because it was red. But you guys knew what was getting at.
Thanks for the answer nickmv.

I just tested it myself and what do you know... the LED has a dim glowing red... very faint but it's there... so no... it's not really in the infrared spectrum but quite close to it nonetheless... but then again it could be a dual colored LED; one with the infrared light and one with the visible light... I don't know...

It is so freaky! But true. Only visible in a dark environment for me.

I was killing time with my one s camera and my remote control, never know u can see the inferred light from a camera, Feels like science class

It's the proximity sensor...you know, the thing that turns your screen on and off when you put the phone to your face during a phone call then move it away from your face...

darn this thread got me excited, thought maybe the One s had another notification light that we could use for stuff! I really hate the placement of the LED on this phone, but I guess its good enough that it even has one. I wish it would glow at least, not just flash. would be a lot more noticable

I noticed it today in bright sunlight. And there is another thingy next to it. Nevertheless I find that red flickering light pretty annoying. It makes me nervous, it flickers like a ethernet status LED. Hope theres a way to turn it off...

Did anyone solve this?
I have a problem with the sensor; If i use my headset, it won't stop blinking after I make a call. If I make a new call and immediately end the call, the sensor stops blinking.
I contacted HTC and they told me that I should send it for repairs...

I remember this red glow of the LED from the good old IRDA transmitters that we had in phones and laptops years ago.
If you look at the light spectrum you'll notice that Infrared is very close to red

+1... I noticed the same "effect" on my phone last night - H/W malfunction? Does it drain a little bit a battery by "sensing" continuously? Or just a "cosmetic" matter?...
Any feedback from HTC or another source? Any way to disable it?
EDIT : "I contacted HTC and they told me that I should send it for repairs..." <- I hope it could be solved without that option ...

Yellowish tint on the bottom of the screen?

Hello guys,
I am seeing a yellowish tint on the bottom left on my screen, but only on some grey background. I'm still on the 15 days returning window so I am thinking of sending my phone back.
Anyone with the same issue? Should I ask for a refund and purchase back a new phone or ask for an exchange?
Thanks.

Like any oled screen. It's a lottery what the colour shift, evenness. If you notice it you should exchange it. It will annoy you to no end

Yea it happens, u could exchange it but whos to say itll be worse or better? Maybe the device will have another defect thats major. Who knows of its really annoying u go for the exchange and pray.

My color shifts a little when grey (I guess like yours) but I feel like it will look like this no matter how many times I exchange it. Still looks good IMO. Just suck a large screen so different angles may shift.

Cause the screen is so tall your always looking at parts of the screen at different angles
