Liquid substance under the screen? It's moire. =)

hi guys. my x50v seems a little 'baggy' in the middle too. worse still, when i tilt the screen some degrees, i can see some ''liquid-like substance'' made obvious because its like a thin layer of oil on water, it has that colourful pattern thing. when i press the area adjacent to the substance with my stylus, the subsance seems to be attracted to the point of the stylus. like a magnetic effect. but after removing the stylus, it goes back to its original position. any idea what is going on? is it a leak or something?

i plan to call Dell tomorrow but i'm too busy to do it these few weeks. also, if it has been over 21 days since the date of purchase, will they still replace it with a new one without voiding the warranty? thnx guys. :rolling:

Pretty sure its normal its that (insert long word here) which is just the miorre (I have no idea how to spell it) pattern produced by the two layers coming in contact and all that with the liquid in between.

Is there anything pushing against the screen? sometimes cases mush against the screen and end up producing those "liquid" spots.

the only thing that actually comes into contact with the screen is the sp, and indirectly , the stylus. i dont think the carry case that came with the x50v actually comes into contact with the screen when the x50v is slotted in. theres quite a lot of it, probably taking up 10% of the total screen area, concentrated in the middle.

i just found out that when i use the stylus to 'attract' the liquid to the sides of the screen, i can see the 'pores' in line order. not sure how it works, but i guess its how tft lcds work. it doesnt affect functionality in anyway, but is it normal?

i think it started off with only a small patch of the liquid, then more and more progressively. this is depressing, takes the mood out of me to study for my test tomorrow. lol...

thnx for replying :)

If you can rule out drool, then you should call Dell as planned.

That's a "Moire Pattern" It is caused by pressure on the screen, such as a case. I've had a permanent Moire Pattern on my X3i since shortly after I received it. Doesn't bother me in the least, I'm more worried about getting a refurb that doesn't work correctly. Anyhow, if you're within the 21 day period, they'll ship you a new one. Be advised that it will most likely return if you have a case that puts pressure against the screen.

There are temporary and Permanent Moire Patterns. Might want to leave it out of the case for a while and see if it goes away.

The case that came with the x50 was/is particularly notorious for causing moire patterns. Have a look at the case reviews on Aximsite and perhaps get one that doesn't put any pressure on your screen.

Look into a case. I have a sena on the way but went 4 months with the slip case and the black part around the buttons has fine scratches from being pulled out of the case. I don't blame dell as it is probally dirt caught up in the fabric. Never thought of washing the case with my socks.

wow. thnx guys. lots of info.

one more thing, if its after 21 days since purchase, will they gimme a new one or a refurbished device? coz im using it heavily and would prefer not to get it changed anytime soon. but if after 21 days, they will only give me a refurbished unit, i'd rather get it changed now. seeing as there are inconsistencies in many refurbished units.

well, leaving it for a few hours, the pattern is still there. maybe the time is too short. hmm.

again, thnx ppl! :)

They can more or less give you a refurb unit any time they like, 21 days or otherwise. I'd give the unit the night off, make sure you leave it out of the case, and see if the moire pattern fades away before jumping into anything.

i usually leave it in the cradle overnight. but the pattern still persists. does this mean that the moire is now permanent? i dont know, i wouldn't like a faulty ( to any magnitude ) unit. i dont really mind the moire, not as much as a faulty unit anyway.

i have to sleep now. its 2am :) biology assesment later. :)

edit : oh, just in case, its been there for a few days already.

There is no liquid, it just looks like an oil slick. It is an interference pattern. See this page on Newton's Rings.

http://www.fas.harvard.edu/~scdiroff...tonsRings.html

The screen must have layers with a minute gap between them to cause this.

My x50v has had this almost since I got it. It is popular to blame the case, but IMHO this is just a trait of the screen... through normal use I bet the layers in the touchscreen come ever so slightly apart and produce the pattern. I'm sure there are people who don't use cases who have the same problem.

In my case, it developed after I put on a screen protector. I don't know if the protector is producing the effect, or if it is deeper in the screen... but since it isn't visible when the screen is on, I don't care.

All y'all getting replacement Axims for this are just driving up our prices. :)

Exclamation How I get rid of moire patterns

When I get stubborn rainbowy moire patterns on my X50v's screen that don't disappear quickly, I find the following technique to work quite well.

Get some sellotape - just ordinary clear sticky tape - and cut a piece wider than the Axim.

Take off any screen protectors you may have on the Axim.

Put one end of the sticky tape on one of the silver edges, left or right of the screen, about halfway down the Axim. Then, while keeping the stuck end secured with your thumb, stretch the tape with some generous force over to the other side of the screen and stick it down onto the opposite silver edge. Make sure it DOES NOT come in contact with the screen yet. Make sure it's also nice and tight.

You should now have a tight piece of tape going across the middle of the Axim, above its screen. Finally is the clever part.

Gently push down in the centre of your tape so that it sticks to the centre point of your screen. Don't smooth the whole lot over, you just want a single little point stuck to the screen.

This gently lifts the top layer of the screen up a little, i.e. doing the opposite of what caused the moire in the first place - pressure. :approve:

Leave the tape in place overnight (or at least a few hours), and take a look in the morning after removing it. Hopefully, most of the moire should be gone. If there are a few spots left, simply redo the procedure but position the tape so that it pulls up the part of the screen with the moire.

As always, this works for me and I can see no harm in doing it. But if you break your Axim through ham-fisted actions, it's your fault. ;)

Hope someone finds this useful. I know how annoying moire can be. :)

Wow. U're a genius. I don't expect many people to actually think of that. Maybe it's just me. :P I just did that, hope it doesnt come back in the morning.

Changing this thread's title, so ppl with similar problems can refer here. :)

edit : uhhh, i cant seem to do that...
