Why do phosphors in PDP...

[Neos]

The additional part to that is ..
- the old CRT's have phosphors.
SO ..why is there is there a higher probability of burn in with PDP over a CRT. I have a 27" CRT I have watched for years and have no hint of burn in under any circumstance.

Any ideas?

I never heard that they were worse than CRT's. Maybe because they're much bigger and brighter? Large rear-projection CRT's burn in easily too.

That may be the reason - the bigger the screen, the more the possibility of IR (image retention), even burn-in. I am breaking my 42" LG PDP in per Pannys guidelines, but I still see IR from time to time. It goes away, but still makes one ponder.
I know that burn in is rare today for PDP's - if they are not abused. I just knew that I had never experienced any issues with this on my old 27" Zenith CRT.
Thanks for the reply.

Screen size doesn't really have to do with it. I just think more power is behind the PDP phosphors.

Actually, each pixel of a PDP is self contained as far as light & power to make it work. Thus translating to more power vs. a CRT?

Had another thought on this. The break in recommended to be done on PDP's today are done to age the phosphors evenly. That 27" I mentioned is about 15 years old (still has a fantastic pix!) - so a lot of it's time was spent on 4.3 - no bars - no logos - and no games. The phosphors in that set were evenly aged for sure if any ever was.
Could be that if one took a similar 4.3 CRT today and during the first year of use subjected it to 16.9 viewing, games, bars and such - there might be a burn in issue with it.
