Do LCD panels suffer from screen burn-in?

[JonB]

Just installed an inexpensive 14.1 LCD panel for a local business. They intend to leave the computer running most of the time, even overnight. Do I need to worry about burning the screen?

I don't own an LCD myself except for a laptop that doesn't get much use.

No, not that I am aware of. In fact, did you know CRT monitors made after (say) 10 years ago don't suffer from the problem either? The only thing I have heard of recently that does suffer from it is certain tv's. When you have a widescreen and it has to constantly draw in the black bars to accomodate conventional television, eventually those bars get burned in.

Now that I think about it, I am not 100% sure, so someone correct me please.

Thats not true, we go through monitors at my workstation at work (4 displays on 24/7/365) about every 4 years due to screen burn in. These are high quality NEC, Compaq and Mitsubishi 21" and 22" CRT displays also. Its not as bad as the monochrome displays used to be for sure, but most definately in an environment such as mine, on around the clock using mainly one main screen (some switching between different screens) for user input, industrial plant setting, you will burn the image into the screen.

from discussions in the home theatre front, CRTs and Plasma Display Panels are subjet to screen burn in but not LCD (or DLP) technologies. This is a huge issue in the use of these displays as HTPCs or casual Windows use and there are so many areas of the desktop that are static. This is one of the primary pros of the latter two display types.

Yep, we have an IBM 15" CRT that has a permanent WinNT logo burnt into it..Damn shame..

LCD's can get screen burn-in too if left for around 10+ and some manuf. do warn you about this.

I've seen an NEC 18inch LCD with a screensaver password prompt burnt in when I was at the Computer Show and you can see that prompt on all white backgrounds.

Why not make the monitor go into stand-by mode when not in use for like 30mins?

We have a couple of Sun FC-AL arrays where I work, and they have small LCD displays that show some status info.

Those displays got very badly burnt in, before we found out there was a sort of screensaver that simply wasn't activated.

i have spoken to design engineers at planar and they said specifically No Burn-in on LCDs. If your LCD appears to be burn-in, turn it off for 3 days and that will solve the problem.

Yes, it's possible ? however it is not really screen burn like CRT?s get. In terms of LCDs it is generally referred to as "image sticking". 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.

Short answer: YES

Long answer: Where I work, we have an ops staff who monitors systems 24/7, On some screens, the same thing GUI stays there 24/7, every year or so, they get new monitors, since thoes are on constantly.
The tube monitors, you could see the burnt in image when it was on or off, it looked awful.
they just replaced an LCD, you can see the image on a bright screen, not as bad as CRT, but it's still there.
