TV's

[Waylander]

Plasma and TFT LCD will burn. True LCD won't.

Paul N (just stuck up 2 x 30" LCD and 1 x 40" LCD and 1 x 42" Plasma before lunch - phew)

Plasmas are heavier then they look aye.


Oh and depending on the plasma you will also get this media box thing that recives the signal and sends it on to the tv and the sound elsewhere. With most plasmas you don't get speakers so you would have to get a sterio to hook it up to. Some plasmas do come with an intergrated media box but they arn't really thin.

As for LCDs not getting a burnt image, it could be true the last time I had heard of any new advancments was litttle over a year ago so they could have fixed that.

TFT and LCD are quite different...

TFT is a variety of LCD. Thin film transistor. Pretty much all LCD screens used are now TFT. Previously it was TN and STN (Twisted nematic and super twist nematic).

TFT LCD displays can not suffer from burn in. With age, individual dots can stick on or off, but because TFT displays are backlit, there is no possibility of burn-in.

a big thing too is televison is only half of it.
sound is a huge factor as well. surround sound is very important for movies etc.
wide screen yes, 100hz yes, high definition yes,
but all that wonderful viewing is all crap without great sound to go with it.
so i hope you have a excellent theature unit.
dolby prologic 5:1 6:1 NICAM crap and then the list goes on.

good luck

I thought great sound and home theatre were mutually exclusive. At least as far as music goes.

OK OK I was being a little 'simplistic'....

LCD's fall into several categories but since we are discussing TV's lets ignore common plane based ones and reflective LCD's.

That means we are discussing back lit Passive matrix and Active matrix LCD's. TFT's are Active matric devices. As you rightly point out, these don't suffer from phosphor burn (like a plasma) but they do suffer from a thing called 'image retention'. This happens when a cell is in the on state for an extended period of time and causes a small change in the cell. Cheaper screens seem (in my experience) to suffer from this more than the heavier duty screens.

The LCD models we use are built for digital signage and are intended to run 24/7 (30" and 40"). To date I have yet to see a single failure of these screens yet I see many failures of the units designated LCD TV.

My demo screen has been freighted, couriered, taken (upsidedown) on aircraft, done trade shows and fallen over in the back of the van... A plamsa can't hack that and if you plick uo one of our LCD TV's, then pick up my LCD monitor you will see what I'm on about... These things are built baby....
