flat screen monitor burn in

I posted a question about this awhile back, and the answers I got
implied that flat screen LCD monitors did not suffer from image burn
in. However, after taking that advice and not using a screen saver on a
couple of new monitors, I now have bad image burn in from a desktop
wall paper image. How can this be happening?

I had to cut and paste the original thread below, for some reason it
would not allow me to reply to that thread.....

I'm wondering if flat panel monitors are subject to image burn in the
same way CRT monitors are? I've learned the hard way that I needed to
use a screen saver on my CRT screens, but now I'm phasing in flat
screens and am wondering if I need to do the same.

As Carey told you: the answer is no, because LCDs use a different
technology altogether from CRTs.

LCD monitors are constructed very differently from CRT monitors. CRT monitors fire electron beams at phosphors on a glass surface, which can cause burn-in if the electron beams are firing at the same spot on the glass for a prolonged time. LCD monitors do not fire electron beams nor do they have phosphors, and consequently they do not suffer from burn in.

LCD monitors have their own unique problem, known as 'stuck' or 'dead' pixels. These are pixels that are stuck in a certain position, so they always display the same color. Dead pixels were more of a problem in the 'olden' days of LCD panels, say about three years ago. Improved manufacturing processes have greatly reduced the incidence of dead pixels.

Therefore, if you really do have an LCD monitor with an image permanently burned into it, your LCD panel is defective.

Unfortunately some LCD monitors do suffer from image burn-in. For example,
we recently purchased several hundred new Dell flat panel monitors in
various sizes: 42", 24", 20", 19", and 17". The 20" monitors (model#2005FPW)
have all experienced image burn-in while the others have not.

Today commented courteously on the subject at hand
I posted a question about this awhile back, and the answers
I got implied that flat screen LCD monitors did not suffer
from image burn in. However, after taking that advice and
not using a screen saver on a couple of new monitors, I now
have bad image burn in from a desktop wall paper image. How
can this be happening?

I had to cut and paste the original thread below, for some
reason it would not allow me to reply to that thread.....

I have a 9-month-old Samsung 213T 21" LCD which has about a
dozen dead pixels it got in the first couple months. I run a
screen saver that flips my car picture collection, but it is
seldom on because I'm working.

I really don't know if LCDs do or don't suffer from burn-in,
but I do know two things: 1) they do die a cruel death from a
number of things, including dead pixels I already have and 2)
it pays to buy an extended warrenty to either fix or replace
one.

For 1), I turn the blinking thing off when I'm not actually
sitting there doing useful work thinking that I might extend
its finite life. However, I also don't know if the several
times a day power-on surge does more harm than the good I get
in 8 hours more theoretical LCD life. Guess I'll know by this
time next year.

For 2), I wasted 1/8 the cost of the monitor for 3 years so
I'm not sure if that is a good investment or not, but if I
never need it, I'm $100 ahead, I think, else I'm $100 ahead
for a repair or a reconditioned old monitor.

Good luck with your problem, I really do hope you find the
answer.

As has been pointed out by M and D and Carey, LCD monitors do not (can not)
experience "burn-in" in the same way that CRT and Plasma screens can. The
way the image is shown on the screen is totally different from CRT's and
Plasma screens. There must be some other process that is causing the
defects in your Dell LCD's. Send them back to Dell.
