water wave produced when press on the screen

HI all, I dont know if anyone has this situation...
Everytime I press on the screen, the screen generates a bit like a water wave and the situation is just like pressing on a LCD monitor.
My old M3100 doesnt have this situation...how about u guyz? do you have water wave when u press on your tytn ii?
thanks

Hmmm, maybe it's because you ARE pressing on a LCD screen... I never press hard enough to see it, but I'm sure it would.

Yea seriously, how hard are you pressing? I don't think you need to be pressing nearly as hard as you are. I can see the ripple if I press really hard, but that much force isn't necessary for your taps to be recognized (and its probably not good for the screen).

I was going to post about this earlier. I too have this problem. I owned an 8525 before, and it never rippled unless you were exerting massive force.
My current Tilt you barley tap it (like say, you are touching the dial pad to call someone) and it has two large ripples happening.
Is this normal for everyone? I called ATT about this, and they just sent me a new one. I just haven't opened the new one yet.

I found this out cos I am using my finger to use the Touchflo...I didnt apply a very aggressive pressure on it...I even see the ripple when I slide the keyboard out. Is it normal?

no its not normal if you are pressing softly and having wave like that. Please do the warranty exchange.

AT&T just sends you a new phone without even asking for the old one back?

I've seen the small ripple when sliding the screen out. Maybe it's the magnetic switch..who knows. Doesn't happen all the time.

I have uploaded a video on youtube about my screen problem
I only pressed it gently on the screen.

Do you guyz have this problem?

Anyone? it seems I am the only one to have this problem...

Hi
It depends on the LCD panel, there are different types of panel, some will ripple when pressed or distorted even very slightly others don't.
The problem with asking others is there are at least two different types of LCD panel used in the Kaiser. One we know to be transreflective that works in direct sunlight and looks kind of green rather than black when off, and one that's not transreflective that is black when off and doesn't work too well in direct sunlight. These panels may well be using different LCD technologies in other ways meaning not everyone will see the same as you.
Mine isn't transreflective and doesn't do this, so perhaps you have a transreflective type that also ripples under pressure. It isn't a fault with the LCD display, rather HTC sourcing whatever types of panel they can get at the time for the cheapest price. You wouldn't normally use a panel that ripples when pressed on a touch screen for obvious reasons, but HTC have. Maybe it was a shortage in supply and there are not many that use this type?

Phil

It shouldn't happen. Exchange it.

They charge you for the second one and then refund it when they receive the old one.

They sent my second one out to me at no charge. They forgot to include the shipping labels...again... so they will probably just end up letting me keep the device.
Anyhow, my Tilt ripples exactly in the same place that the video showed, and in the same way.

Is the ripple gone for your second one?

Where is your Tilt made?
What's the model code under the battery (ie. KAIS300)?

We don't know this at all, there apparently are at least two screen types but neither was transreflective, both blew out in direct sun.
The ripple is a function of the thickness of the glass screen. Since liquid crystal displays work by electrostatic twisting of a liquid suspension of quartz crystals thereby bending the light to allow it to pass thru polarizing filters, any physical movement of this suspension will also cause visible light artifacts. So if the front panel is lighter weight material, it will show more "ripples" if pressed firmly.

There are different technologies used in the production of LCD panels and how the glass is spaced to give room to create the pockets for the liquid crystal.
Some displays "water" when you press them, others don't, it depends on what the type of LCD display it is. My monitor at work can be pressed and nothing happens, my one at home is the opposite. It's not hard to find this explained on the internet.
The Kaiser is using different types of display using different technologies. Typically for touch screen applications (unless the display as a touch glass front) would not be of the type to ripple when pressed for the reason it will be pressed and flexed, but obviously HTC is supplying anything they can get.

Rainbow Effect on Screen

After being in my pocket for some time, there is a rainbow effect on the screen. I can change the location of this effect if I push elsewhere on the screen; however, it seems to concentrate itself right in the center. It has no ill-effect on the touch screen but it is visible under certain angles when the screen is on. I am using the screen protector that came with it. After some time being out of my pocket it dissipates and looks normal.
Anyone else experience anything like this?

Yeah, I have.. I haven't noticed it's touch sensitive, but I've seen the problem while rebooting and also randomly while using the phone.. And it seems like for me the screen gets progressively worse and starts losing all contrast and fades to white. A reboot always fixes it.
My guess is something in the video drivers flips out. But the first time I saw it I thought I had a hardware problem because I found it that way in the morning out of the blue, but I guess it had started doing it 'itself' overnight or something.

I dont think it has anything to do with the screen itself. But the digitizer and the multiple layers on top of the screen that the digitizer is composed of.

Newton's rings isn't it?

Yes that is exactly it - the diffraction of light between 2 surfaces, is it normal; however?
Thanks!

Nooo, then maybe what I'm talking about is different. I'm talking crazy screen, weird 'rippling' going on, screen slowly turns more and more white. I know what newtons rings are.. It's sorta visible in sunlight.
So perhaps I'm describing a different issue. Mine is definitely something with the phone, not the layers.

screen defect?

I just got a tilt about a week ago and ive noticed that in the middle of the screen there seems to be a purple greenish tint when put against incandescent light. The size of said glint varies in size but i'm unable to see what changes the size. Not sure if its heat or pressure or something. The touch screen works perfectly its just really annoying to always see such an annoying glint.
An interesting discovery is that when i press all four corners of the screen it disappears and when i press in the middle of the little square it seems to spread out. I feel like theres some kind of material or something in the touch screen that is causing this due to pressure. I keep it in a hard case in my pocket so the screen isnt pressed on inadvertently.
I've searched the forum for any answers but i havent seen anything about it. Any response or help would be greatly appreciated. I'll try to get a picture of it up asap but i left my camera at a friends house and dont know when im getting it back...thanks in advanced

Do you see the same "annoying glint" under neon light (not day / sunlight)?
Lots of NOKIA and SONY ERICSSON phones for example get this screen recolorization under direct sunlight - this has nothing to do with the screen being defective but with the plastic above the screen which breaks the light and shows you this colored spots. If you can't see the same spot under direct neon light then this might be the cause.
It is normal that you get color changes while pressing the screen in. First of, you press / bent the protecting plastic and the liquid within the screen which causes the incoming light to break in a different angle, therefore the color changes. (BTW: you shouldn't do that too often, it can cause permanent stains on your screen!).
There sure is the possibility that your screen gets pressure from underneath due bad assembling! If you're still under warranty, try to get a replacement.

yeah you cant see it in day light. but i feel as though there is constant pressure on the screen between the plastic and liquid since the spot is always there and doesnt really go away (unless of course in daylight).
well im thinking im going to go back for a replacement. thanks for the quick answer!

Strange circle/ring in the middle of the screen

Recently, I noticed the is a strange circle in the middle of the screen. When the screen backlight is off, it appears as a black circle. When the screen backlight is on, it appears as red/yellow/black ring. Somtimes it went away by itself, and other time I have to "wipe" it away with finger force.
Anyone know what is wrong?

2 questions
1) Have you tried removing the screen protection just to see whether its on the screen protection or on the main lcd screen
2) did you ever exposed lcd it to high electromagnetic waves??

1. I didn't remove the screen protector as I believe it's beneath the LCD film.
2. I don't think it has been exposed to any electromagnetic waves, as it appears after I pulled it out from my pocket.

I've had it too but it's gone now
I had the exact same problem a few weeks ago. The place I stayed was not well ventilated and I THINK it caused some water condensation to occur between the digitizer and lcd screen. I slept in an air-conditioned room the next day and it was gone!
My deduction is that you need a cool or cold environment for the stain to evaporate.

The same problem arises again, and this time it has been a couple days but it still did not go away.

It looks almost like a burn mark.
You may have a defective digitizer.

Found another thread talking about this:
http://forum.xda-developers.com/showthread.php?t=439410

This is the so-called 'Newton ring' in optics/Physics. It means that in that area, the thickness of LCD is slightly thicker/thinner than rest of the area. This is normally due to stress at that point. It is annoying but if there are no repeated color rings, like red/yellow/blue/red/yellow/blue, it should be fine. If you have alot of repeated color rings, the LCD may approach its life end.

Thanks for the info. When you said it should be fine, do you mean it will disappear, or it just won't affect usability?

It may disappear if the stress is released, e.g., you push the area a bit or you put it into different temperature environment. But I doubt it will disappear for ever. It was not there in the first place then it came. This means some sort of stress/pressure built up there. It should not affect your daily use a lot. It is just a visual effect. But if it gets worse, the colour rings will become very dense and sharp. It will affect you visual. I had a phone pinged on LCD sometime ago. It had similar rings like yours. But it was so dense I could not see any thing behind it. I had to change it for £35.
Also I looked at another previous comment about the humidity. It could give you the same effect. Maybe you can bake your phone a bit?

[Q] Imprinted Markings on the Screen

Hi All,
When I bought the phone it was enveloped with a sticking transparent cover (as the ones you find on new phones, at least here) and the sticker on the screen has the samsung logo and Wifi/GPS and stuff like that written on it. The thing is, when open the market or scroll down the notification, I can see the residue of those words and markings imprinted, granted it is hard to spot but very annoying.
I have been trying to capture a photo with my camera but didn't succeed so far. Anyone had this problem before? or any ideas? is it a permanent damage to the screen or those are residues that can be removed?

Haven't noticed anything like that, but I suggest you try to clean your screen.
For cleaning I used a PC LCD screen cleaning solution, spraying it on a soft, clean paper towel and rubbing the screen lightly with it, taking care not to let any liquid in the phone speaker holes or the home button. Afterwards wipe the liquid with a clean, soft, dry paper towel. Makes my screen shiny and clean as new.
If cleaning doesn't work, I suggest you get it replaced.

Ok I've managed to finally take a picture that shows what I am talking about. The white note shows the exact covers that was on my phone.
Notice the HD Amoled and the circle around it? that's the one I can still see when the screen is showing colors same as the one in the picture. I can also see (but couldn't take picture of) the words GPS, the Wifi logo and a circle (android logo) in the bottom.
any ideas? is that permanent? is there a way to remove it? people don't notice it on my phone, but since I know it is there, it's becoming more and more annoying

I didn't have those stickers on my phone...
