OLED is massively better than LED and a completely different technology. The depth of colour etc is far greater. Allows for true black etc which you can never have with a back lit LCD TV.

I've had OLED phones for 6 years now, went back to an LCD one for a year before getting another OLED one last year and absolutely hated the screen. (HTC One m7 so wasnt a budget handset either)

OP I currently game on a Panasonic plasma TV which used pioneer's kuro technology, however you can no longer get that sort of TV as the tech was unable to scale up to 4k sets so has now pretty much been abandoned.

My next TV will definitely be an OLED. Personally prefer flat to curved screens. But you do have to shell out a premium due too them being a more niche market and the technology is still pretty early in its development. I think they'll become much better priced in the next 12 months or so.

Really depends if the quality is worth the premium. But to me definitely yes.

OLED phones are great, as is the OLED Vita. 

But I would wait on the TV. Sony makes their own OLEDs, and could actually release them cheaper than LG could. But they don't, because the technology isn't ready yet (and might never be). LG is jumping the gun and sacrificing a lot to do OLED, not to mention virtue of being LG ruins things, too (bad processor, bad upscaling, bad noise algorithms).

If you call Sony and ask them why they don't make an OLED, they'll tell you they do. It's a 32" monitor with the most perfect color and input lag. It also costs $30000 and the half-life on its blue is 6 months. OLED isn't ready, and the fact that Sony and Samsung aren't doing it should really drive the issue home.

This definitely makes sense. I heard recently that Sony is preparing some 4K LED TVs that use more advanced LED technologies to reduce the number of backlight zones. It should get LED TVs closer to OLED without giving up the benefits of LCD, but the downside is it's still really expensive.

I'm hoping my Panasonic Plasmas will last me long enough for OLED to mature aa fair bit more yet.

I understand from the manufacturers not doing OLED though, is more down to they can't make the sets at a price they want to sell them at and are not bothering at all. I'd heard that the Panasonic configuration of the LG OLEDs was actually a pretty good leap forwards. Like you say though the technology needs a bit more time to be at it's best. But OP isn't looking for right this second, and I'd expect the next batch of OLEDs to resolve most of their current issues.

1. Your plasma is likely already showing the effects of its half-lifes being breached. If you were to set up a new version of it right next to it, you'd likely see a substantial difference in the saturation of the blue.

2. Haven't personally been able to see the Panasonics, but if the quality is anything close to the x400u models... Then it's likely just a hot pile of garbage.

3. If OP isn't looking for a TV between now and April of next year, then he likely shouldn't be looking at all. TVs can change so drastically from year to year that it really isn't worth even looking into until you're less than a month out from purchase.

This is the set:

http://www.hdtvtest.co.uk/news/panasonic-tx-p42gt30b-p42gt30-201103281070.htm got a 46" in the front room and a 42" in the spare room.

Was certainly far from a piece of garbage :) even with an ageing image quality, you still can't find an LCD anywhere near the pricepoint I paid that comes close.

Picture of my troll den : 

Get a projector. I use a secondary screen, and a tertiary (not on picture). I've bought recently a BENQ1070+.

Oh, my bad, I wasn't specific. I was referring to the Panasonic OLED, not your plasma.
