LCD Burn-In ????

Color me confused.
I purchased a Samsung LN-S3251D LCD panel HDTV last Saturday evening.
Looking at the Owner's Instructions I find a warning box saying that
displaying a fixed image or 4X3 images for long periods may cause
permanent damage to the TV screen (burn in). I thought LCDs did not
have this characteristic (as CRTs and Plasmas do) and was one of the
positive points for choosing LCD over Plasma or CRT.
Could anyone clarify???
Thanks,
Larry

Yep. working on redefining that at HD Library...

It appears NOTHING is impervious to burn in.

Have had reports of DLP having 4:3 burn in but that can only be due to
something in the light path aging from the light - it ain't the DMD
device! That said mine is at about 10,0000 hours and 80% of that was 4:3.

LCD RP or FP can burn too.

As I told a recent customer...

Quick point here; LCD is not impervious to burn in. Note that the
computer industry is running screen savers. What this means is while not
impervious it is far more resilient and appears to have the same level
of potential as a direct view CRT. That means don't leave static images
on the display thinking nothing can happen and by all means watch some
full screen content.

Beyond that I am still figuring it out and unable to get any hard
statistics on what it takes, hours, to cause it. With LCD I am told it
has to do with the liquid part of LCD, liquid crystal display, getting
stuck in a molecular state. Some LCD displays have a built in WIPE
feature to remove it. You could feasibly feed it a full white raster and
accomplish the same. Another thing that just came up too is if you break
one don't touch the goo, the liquid part of LCD, that might be secreted.
Supposedly Mits has this warning in their owners manual and may be the
only manufacturer doing so this year.

I have heard of LCD panel companies and retailers bad mouthing plasma for
burn in. But LCD's have what is called image retention. Isn't that
basically the same thing?

Richard are you saying you're DLP burned in or that you have heard reports
of it?

Image retention is the technical term for burn in.

Reports of it and mine is fine. A DLP with this problem is very rare!

“Image retention” also includes a temporary phenomenon that LCDs are famous
for. This “image retention”, which goes away in about 30 minutes, would
not be burn-in. -Ken

You are correct but there have been cases where it did remain requiring
replacment of the LCD panel.

What a coincidence... somebody at NESDA asked the same thing and one of
the reps said what I said...

He did add that LCD is more resilient than CRT DV but he also has no
specs as to when and how long...

As he pointed out, too many variables

What kind of programming, contrast settings, brightness, IRE levels, ect..

Richard,

Interesting how things turn around.

Would you take them to court because they use that as one main differentiator from plasma and CRT to sell their panels. Is that meaning that their sales speech was actually a dirty secret to the public?

What happens now from the plasma point of view? Should they do a class-action suit? This is similar to what we were discussing recently. There is no way to win as a consumer in this market, they will make you believe what you want to believe after being drilled on the head often enough.

Now that plasmas have the features of image shifting at intervals to protect the panel, a feature I have not seen on LCDs (perhaps to avoid looking contradictory to the bragging of LCD "never worry about burn-in"), plasmas should become a better value, lower price, larger, better colors, etc., with similar burn-in worries.

This was discussed several years ago on the mag, and I remember there was a dealer on the discussion that suddenly joined the exchange and said: baloney, they had a LCD panel on the showroom that was so burn-in for fixed logos that they had to turn if off, the unit was apparently on most of the day, but which other TV doesn't on a dealership?

Bottom line, do not ever trust claims without facts, this is like the FDA, they expect the public to do the actual test, if you do not get cancer taking pill ZZ, great, by the time the true is out the approvers are retired.


Best Regards,

Rodolfo La Maestra

Rodolfo,

I grant you the world is not perfect.

>>plasmas should become a better value, lower price, larger, better
>>colors, etc., with similar burn-in worries.

Similar burn in worries? Where did you get that? Plasma can't touch an
LCD in this area nor can a CRT DV. All I have stated is that LCD is not
impervious; it is possible.

As for manufacturer claims... I stick to what I have already stated. If
the manufacturer chooses to not protect themselves from the liability of
their product by providing full disclosure of their products
capabilities and limitations then they must also assume the liability of
of doing so. In my LG example that means taking the display back with
minimum hassle rather than making the consumer, dealer or distributor
keep it.

That was the case with CRT RP and burn in and you will note that
suddenly manufacturers started putting disclaimers in the owners manuals
about it so they could not be sued.

The key is getting such cases to court as that is what forces the change.
