[Q] LCD issues - Xperia Z Q&A, Help & Troubleshooting

Hi anyone tried gently pressing the left border of the screen and notice some LCD ripples whereas the right side isn't so obvious? Or isit just me and is this a care for concern? Appreciate ur replies thx!

I seriously dont understand any of you people. you are like the 5th one now? asking the same question over and over again. Its like a LCD/LED monitor, but without the "thin glass" surface.
its a screen with a thin glass surface, you press on it of course there's ripples or waves or whatever, like you want the phone screens to be made out of metal or super duper thick glass or something? and fyi when you use the terms gently, or gentle, or lightly press on the screen it doesnt mean you are pressing on it gently. Obviously you are pressing it hard enough to cause that ripple or waves effect. -.-
i can gently touch the monitor and see a little ripple effect, and i can do the same on the phone but see no ripple effect at all.
I believe most of you people are pressing on the screen too hard, learn to "touch" not "press." its touchscreen not press-screen.
PS: my apologies for the tone/choice of words used in this context, had a bad day.
PSS: but seriously its touchscreen not press-screen.

Thx sry as this is my first touch screen phone... But my question is, it isn't uniform... As 1 side is more obvious then the other. Is this a normal thing for the Xperia Z?

well nothing is perfect.
my z's back panel, upper right corner is sticking a bit out more than the rest of the corners.

Galaxy S2, Galaxy S3, Galaxy S4 and iPad doesn't get screen rippling.
I had this problem with the XZs I had but only on two later manufactured models. (I went through 8)
There must be something under the screen on the lower left which causes pressure thus making it easier to cause the ripple in that location.
Just dont have it in your back pocket and sit on it.

Strange Screen problem

Not sure if anyone else has noticed or has this but when my screen is off it looks like there is fluid or something on the inner part of the screen. Almost like grease looks like on water .
Any ideas anyone.
Same problem here! It´s only in the middle of the screen - (1 cm border) - the same for u?
you can only notice it when you tilt the screen to a light! you dont see it in the dark..
It's probably just the screen protector...
I honestly cannot see anything like grease on water below the screen when the phone is off. Possibly because all I see is grease on the screen from my fingers.
its just where the original screen protector was on it. I had the same. 1cm border arround screen. just give it a good scrub with a soft pollishing cloth to get it off

Yea , same for me . Sorry but its not where the sreen protector is as it has never had one being tempered glass.
Hmm sounds like a warranty return then
it should have been a protector there. sure it's tempered glass, but the digitizer on top of it is plastic.
same problem
I have the same problem on the middle of the screen: 1cm x 2cm area.I can see it with dark background. If I tick this area with the stylus, it moves like some fluid.
I will try to take photos later.
Its under the glass , there is no screen protector on the device. My camera is broken so hopefully some photos will come up later
I have the same problem on my "original Touch" - I noticed that it's visible only when screen is pointed to some polarized light (for example laptop display, fluorescent tubes in subway). In the subway I can hardly read the text. Under the sunlight or under the normal bulb it's not visible (or barelly visible from very sharp angle).
I heard there is some polarization film under the plastic-glass that can get released and make this liquid effect.
My friend noticed this even on his Eten x500+, but not so bad.
This was one of the reason I get my Diamond - because I need to send Touch for warranty repair.
It's a bad news that this problem persists on Diamond
look at this http://forum.xda-developers.com/showthread.php?t=293311
Yea I think the last user is probably right . I keep it in my jeans front pocket so it could be presure on the screen.

Applying too much pressure to amoled screen?

so I was installing a new screen protector yesterday, I was pressing down the bubbles with my fingers, over a microfiber cloth of course, and applying pressure to single points on the screen with the tips of my fingers to get the individual bubbles out. I now at the time I was using alot more pressure than what I I shoud have
I didnt realise how hard i was pressing down and then I stopped
the screen was not tarnished at all, bo bruises or spotting on the particular areas I put massive amounts of pressure on
now I can guarantee you that if this was an lcd thier would be some sort of bruising on the screen, lots of it actually. my main concern is that I may have used to much strenght ( im a big strong dude haha) is their any chance I could have messed something up
I know lcd and amoled are differnt technologies so can someone explain to me how its built, why thier is no brusins and wether I should be worried about this, I would just like to understand the tech because im pretty suprised that nothing happened to the screen
but maybe something I cant see or that may arrive later, I do understand their is glass. Does it have any give etc?
like is the does the glass protect it enough to actually keep pressure from reaching the amoled tech?
I did the same thing; wondered the same wonder
Like, word for word that's what I did putting on my protector, and was amazed just as you were at how damn strong that screen is. Amazing ****.
Gorilla Glass is some strong stuff. Next time though, try using a credit card or a really thick business card.
Use the edge of the card to push the protector down. Do this in a forward sliding motion until the protector is completely applied. Doing this will make it a lot easier to get the bubbles out.
Also, I typically use rubbing alcohol to clean the screen. Afterwards, I use some Scotch tape and tap it across the screen. This will make sure you have cleaned off any remaining lint and dust.

[NEW POSSIBLE ISSUE] Screen Flex

DO NOT complicate this with the screen separation issue, my device does not have this issue.
When on a black screen when pressing the devices screen, it does not have to be hard just medium, the screen will flex causing the display below to ripple. It reminds me of the HTC One X screen flex issue at the top ends of the device where it was curved.
I have made a video showing my findings, I know at times it looks like I'm pressing extremely hard on the screen, I'm not its just because I was on a soft surface and so the device pushed into the bed. :angel:
Oh and your probably better watching it in full screen, just watched it embedded on here myself and it's hard to see
It's a TOUCH screen not a PRESS screen. Be gentle... you meanie!
I saw what you meant once in that video, but it did look like you pressed pretty hard. I tried to replicate it to no avail. Sorry.

I know I know, honestly though I promise you I was not pressing hard. Honest truth I noticed this issue because I held the device with one hand, and I was NOT pushing hard.
I've noticed this minor issue on mine, but on the left hand side of the screen. Doesn't bother me too much.
It probably happens because your device has the screen lift too? or the screws are loose.
As before I did the washer trick my screen also did this on the left side only, it was spongy too, once I did the washer trick it didn't do it again. :good:

Yeah I don't really see it as an issue, as long as my device works that's all I'm bothered about and I mainly use my iPad anyway.

Hmm, well the screen doesn't appear to be raised ANYWHERE and I only just got it yesterday (14th August).
My second/current one does this. But only on the left side. If you press on the black bezel around the screen on the bottom third. You'll get the ripple. Nowhere else though. And you have to press it pretty hard. It's not an issue.
No screen lift on this one. Screen lift was replaced by this ripple. That's actually how I noticed it, checking my new one for seperation, and spongy feel. Which it doesn't have.
Isn't this just a trait of LCD screens?
My One X has the same thing and has a Super LCD screen.

LCD is the screen itself, it is a trait however the bezel and glass should stop this from happening, because obviously if this happens a lot, then device is going to be damaged

Yeah. If you see ripples, you are applying excessive pressure to the screen. This is standard for any LCD, not an issue.

Well said. Not an issue.
Yeah, I'm saying that because my old laptops did the same thing when you touched the screen. Not a issue...
Phones have Glass over the screen. You don't actually touch the LCD. You have the LCD, then the digitizer, then the glass. So I think this is because the LCD is too close to the digitizer because of the screw issue. I had screen separation issues on the left side and this ripple. I made some "washers" using some medication foil packaging (3x) and not only did it fix the screen issue, but the screws are nice and tight (fixes squeaks) and pulls the screen down away from the digitizer so you don't get this effect.
Mine USED to do this (mostly on the left side) but now it doesn't after I put in those "washers". The bottom left is more sensitive still but requires lots of pressure still. If you press hard enough on the screen the LCD will still ripple.
RMA and chill.
I'm sorry but these threads are getting tiring now.

Mine is mainly on the left side as well, its actually quire hard to recreate it on the right, though its possible. I'd just like to assure readers that I am not using excessive force on the screen at all, not even close. As I said, I can recreate this just by holding the tablet with one hand!

wow, this has to be the biggest non issue for the nexus. it's a LCD if you press that hard of course the screen will ripple. yes the top is glass, but the nexus 7 screen uses a new process with less layers of glass to minimize thickness.
Do you have a laptop or lcd monitor? Press on the screen and see what happens.
OP you are pushing way too hard to simulate normal usage. The screen is covered in thin glass not bullet proof glass and if you push to hard it will flex and distort the black light and cause ripples.
Seriously this is a non issue.

Yeh I got ripples if pushing to hard but had the common sense to understand this is not a fault its LDC my old omnia phone does it.

HAVE ANYONE FOUND A FIX!?!?!?!

Will a screen protector interfere with the digitizer's pressure sensitivity?

I'm a graphic artist, so I do a whole lot of drawing and drafting. The Wacom digitizer is actually one of the main reasons I'm getting a Note 2 actually haha.
I've never used a screen protector on any of my phones, but I'd like the GN2 to be the first. The only concern I'm having is that the screen protector will interfere with the stylus' levels of pressure sensitivity while drawing and writing.
Does anyone know if this is the case?
JLG http://www.amazon.com/Just-Like-Gla...id=1354559982&sr=8-2&keywords=just+like+glass is what I use and it is the best I have ever used! No issues at all with sensitivity levels and it is actually smoother than the bare glass!
Have you noticed it affecting the pen in any way? Sensitivity to pressure?

Just installed JLG as well and pen sensitivity is still as good as the stock glass.

awesome, I'm gonna have to order one!
Just for giggles, I just tried the stylus through one of the clear cd spacers you get with a spendle of disks. Works just fine though it. I'm pretty sure as long as it's not thicker than the hover distance, a screen protector isn't going to affect the stylus.
Thanks to everyone in this thread, I had the exact same question/scenario, but couldn't find a specific enough answer.
I think the pressure sensitivity etc is all done on the s-pen end of things. If you hover the pen over the screen so the little air view circle comes up you can click the nub on the end of the pen in and it registers as a touch, and testing in s-note, line thickness varies with how hard you press the nub in. Judging by this as long as the screen protector isn't spongy or soft it should be fine.

It won't cause problems so long as they are not too thick as to activate hover function.
(A basic overview of how it works)
The S-pen is an active digitizer. The screen actually emits a signal... the stylus has a mechanism in it that resonates with the signal. It is passive so no batteries are required in the stylus. If you notice the tip of the stylus can actually move in and out a little, this is what does the pressure sensitivity. Touching the screen causes the tip to compress a little and it actually alters how the stylus resonates the signal from the screen. More pressure means more change and the digitizer reads it.
This is also why some styluses can have a drawing and erase end. The erase end resonates differently and the digitizer can differentiate between them.
Hope that clears it up.

Lcd 'wave' when pressing the border

Anyone is experiencing this tipe of problem?
When I press (very softly) the border of my phone I see a liquid crystal wave like when you press with a finger on a computer monitor.
This problem is localized only in one spot: on the left side about two centimeters from the bottom.
I.e. Put your finger just above the navigation bar or slightly higher and press to the right on the glass stripe of the side. Of course this is difficult to see on white background so maybe try on a coloured background.
Can this be eligible for a repair under warranty or this is not a real problem?
Thanks for your feedback!

R: Lcd 'wave' when pressing the border
Ok thanks, just bad construction i like very much this phone, just wanted to be sure it isn't only my problem

So every computer monitor is badly constructed? Try dropping a computer monitor in the floor outside and see how well that works.
The Sony reportedly uses a softer glass so that it is more flexible and bends instead of simply breaking.
Have to say this is the most sturdy phone I've owned. Stop pressing the screen in lol.
also they dont use the technology the other LCD manufacturerers use thats the air gap between LCD and the glass , thats the reason u get precision

I think you can catch the difference between the use u have with a phone and the use you have with a computer monitor, right? Or you keep pressing on your monitor hoping this will evolve to touchscreen?

I don't pass my time pressing that part of the screen i just noticed that playing angry birds
my last question is: this "waves" damage the screen/lcd or whatever else or i just don't have to worry about them?
