LCD Burn-In??

[jj1492]

Is it possible to get a "burned in" image on an LCD monitor? I know the old monochrome monitors were very susceptible to it and even the new CRT's can get it, but can LCD monitors get it? Why or why not? Thanks.

Don't think so..CRT work be having a electon beam hitting he phosphors on the underside of the glass face....you get burned images if phosphors are subjected to repeated electorn beam expousre........................LCD monitors use's tranlucent LUD crystals with back light......so it can't possbily have images burned into it..

No

I never thought it was possible but from my post in this thread...

One thing that I noticed about my LCD is that it seems to have a slightly burned-in image on it as if it came out of a hand-held game or PDA. I didn't even know it was possible to burn an LCD. It's not really that bad and it's only noticeable when there's a large area of a light color on the screen.

A few other people later posted that they saw the same thing on some of the same model screens. :Q

I suppose it would be possible for anything to show 'burn in', although proper LCD implementation would require that to be many lifetimes.

I'd think that would be the lcd waring out in those areas, rather than "burning" anything.

Well, I don't know if this works the same for "monitor type" LCD's, but I'll give a real life example of LCD burn in.

We have a couple of Sun A5x00 FC-AL disk arrays at work.
Since we didn't know how to put them in "screensaver mode" they displayed the status of the disks that were in them all the time for like...2 years.
And that's BY FAR the worst case of burn in I've ever seen.

A Sun guy that came by to fix another thing fixed it, but you still have to stand close to see what they're actually supposed to show, since the burn in shows 22 perfectly fine disks.

These are like 2" displays mind you, but still LCD's.

Yes, it's possible and in fact quite common. Look at just about any ATM machine and you will see what I mean. However it is not really screen burn like CRT?s get. In terms of LCDs it is generally referred to as "image sticking" which looks just like screen burn on a CRT monitor.

The cause is a bit complicated, but it generally comes from not maintaining the proper voltage (i.e., having a net zero DC voltage, long term) across the LC cells. Any amount of leakage current will turn a cell on slightly causing an image to appear.

It is my recommendation to use a screen saver and change the background pattern. On the bright side, unlike CRT monitors in time the effect may fade. If your LCD has this phenomenon, try running a pure white screen for a period of time, this also can reduce the effect but may not remove it completely.

Manufactures typically will not warranty against image sticking (screen burn)

I read this once in my KDS rad-5 manual and it said not to leave on the monitor for more then 10 hours on the same image to prevent from image burn-in. I've seen CRT monitors that have an image burnt in but those monitors don't work on the same principle as LCD monitors.

No burned image on a LCD - however - if you are away for awhile - it is best to turn it off so you don't waste the backlight. It has a finite life like most any light bulb.
