Plasma TVs

I don't expect any of us have the money for one of these things anyway, but I thought this worth shareing.

I was at a research conference this weekend and I heared a presentation by a fellow chemist who is working on a way to improove the liftime of the blue phosphores that are used for part of each pixel in modern plasma displays. the problem is that the ones currently in use degrade in efficency by ~80% over three years!

what does that mean? if you buy a plasma TV now, in two or three years it will only be able to display red and green, and you will have to buy a new one because it will look like s**t. not really worth $3,000 is it?

My college (University college, not school version) has had one for 2~3 years and it seems fine, it'll depend how much you use it and not just for how long you've had it...

allot of people have told me theyre crap & screw up uber quickly.

I'll stick with my 1980s klunker TV. It even has it's own letterbox mode. (Over time it has squeezed an inch of black on the top and bottom in, so everything has a letterbox feel :biggrin: )

That's a good point, I've no idea what useage perameters are used when they say "3 years"

I heard that they will run out of some chemical at some point as well. But to be honest, if you are buying one now, you are the kind of person who will be able to buy a new one when it wears out surely?

Wow Des! That is so damn amazing. /me wants

Be interesting if you could sort of 'polarise' the fog in layers and have a pseudo-3d display...

Er, light polarization is only usefull for steroscopic displays if you are wearing glasses that only allow only one polarization to reach each eye, but yes, I'm sure you could do that with this fog system.

I see nothing technicaly impressive about the fog display. you could do it with any projector and a fog machiene provided you could engineer a shear flow system to contain the fog to the apropriate area. while it might involve some fairly complex gas flow dynamics, it in no way constitutes a new display technology.

yeah, and when every time your fan rotates in that direction... there goes your picture!

cant say as ive seen one for under 6k around here, of course, omaha is somewhat back-asswards....sortof a "lost in the time warp" thing....and the bigger ones go for upwards of 10 grand.....but then again, i dont get out much these days...

Doc Brass... :dodgy:

ps....if i was to spend that kind of money on a tv, it better come with 4 wheel drive and a health card laden hooker as an option.... :heee:

Does this include LCD computer screens?

I wouldn't think so as they are liquid cristal displays and not plasma.

DOH!

kicks self

I'm not entierly sure how LCD displays work, but I'm sure that this issue does not apply to them.
