Does LCD suffer burn in effect as well?

Does LCD suffer burn in effect as well?
If so, how severe would it be? and what is the recommended time to change the image? (as burn in effect happen when you display a image and pause it for a long time. My question is what is the recommended time to make the transition. Plasma is around an hour or two)

 
No burn-in image I am aware of. That is caused by long term burn on CRT phosphor coatings - LCDs don't have that. However! They are illuminated by a backlight, and that has a finite life. Therefore, the best solution is to turn it off when not using it.
 
Not really but a burn out.....the LCD screen just looses its image quality over time, to where everything looks too light of a color and no adjustment helps. Also on most newer LCD's, Ive seen their backlights go out way more often that they used too. (5 years ago compared to today)
 
I have seen an LCD get burn-in, and believe it or not, it was one of the Dell FP series. I do part-time consulting work for a doctor who has one at the front desk, and they've been leaving it on all the time (with no power save mode) and I can see the Windows 2000 "locked" screen if the background is dark enough. Don't know why/how, but it's there.
 
I've seen a few LCD's burn in, big time, though they weren't exactly the kind of LCD's you have on your desk.
They were built into a couple of Sun StorEdge arrays, and displayed status messages and such, unfortunately we didn't find out that they had a screensaver until a tech guy from Sun paid a visit for a completely different reason, and saw the burn in on them 🙂
 
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.

No manufacture that I know of warranties against image sticking (screen burn)
