Hi, where ios the tech difference between all of the above... and at what size tv will differenc be noticeable? thanks
LED,OLED, 3D versus LCD

Hi Kimbiz,
LCD TVs are the cheapest available they will still give you a great picture but......
You then have LED tvs, which are LCD tvs with better lighting so, for example your darks will be darker and your lights will be lighter...
Then you have OLED TVs which are not only the thinnest but also the top of the range because they will have the best picture quality in terms of colour and brightness and they will use the least power.
3DTVs are not out yet, but they will be, however this technology is in its infancy and is likely to be very expensive.
In terms of TV size where it will be noticeable, you can't really get OLED TVS smaller than 37" . So that decision is almost made for you.
Any more questions please do ask.

No manufacturer is yet selling large OLED tv's. Mitsubishi showed a prototype of a 155 inch one at the CAETEC show this year. Sony are planning on launching 21 and 27 inch versions, and samsung a 31 inch version but no date has been announced. LG are hoping to launch a 15 inch OLED in Korea later this year.
The largest OLED tv available is the Sony XEL-1 which is an 11 inch screen.
They are thin, but there is some 'debate' about whether they are more energy efficient. For the phones and mp3 players they are presently used on they do look good with high contrast and rich colour gamut, but don't perform so well in bright light.

LCD TVs use an LCD screen which is BACKlit using flourescent lamps placed directly behind it.
LED TVs also use an LCD screen but light it using LEDs instead of flourescent lamps. The majority of 'LED' sets on the market use edge lighting - clear LEDs are positioned around the edges of the screen and the light is bounced off a reflective surface/prism behind the screen. This is not necessarily better than a conventional LCD.
Some LED TVs use rows of LEDs behind the LCD screen and provide much more effective control of backlighting within small zones of the screen. The new Sharp LEDs mostly work in this way and should represent a good step up from Samsung's edge lit models.
Best of all is RGB LED backlighting where the LEDs used are coloured. This method brings better black levels and more natural and accurate colour tones and can be seen on Sony's X4500 series (46" and 55") and on Sharp's earth shatteringly expensive flagships.
OLED is still in its early stages. The 11" Sony sold in small quantities and the technology is still very expensive to implement. I would imagine it would be at least 4 or 5 years before OLED has the potential to become a mass market proposition. I also believe the technology isn't THAT reliable yet.
3D sets are in development as we speak and prototype designs are already being shown at exhibitions and shows. Next year will see this start to take off in the market.
Finally don't forget plasma. There are less manufacturers working on it these days but the (now discontinued) Pioneer Kuro range is excellent and Panasonic continue to work on the technology and maintain a strong belief in it. Anyone who underestimates what Panasonic can do (particularly with ex-Pioneer Kuro engineers working for them) is being more than slightly blinkered.

You need to get the ECO message in your sermon! LEDs are 40% more power efficient and Plasma will give 40 longer life span than LCDs. You forgot to mention LG. You want to get the latest edition of T mag and see what LG have to offer....will give OLED a run for its money. The koreans aren't *** footing around.
We don't want Sony sales talk, be neutral!
Sony does special ECO ccfl lit TVs but those are the top models.

I popped into John Lewis on Oxford street this afternoon. They had the 11" Sony OLED on display for £3299 and it was generally very impressive. One thing I noticed which surpised me, was that there was quite an obvious flickering on some of the images, which I found quite irritating. I'm not sure if this was due to the technology itself, or the display material.
Has anyone else seen one of these and noticed this flickering?
Other than that, the colours where great, the black levels superb, no motion or judder issues, and no artefacts or picture noise, though it was probably displaying a disc designed to get the best out of the screen.
Whilst I was admiring the thing, a 75 year old man started talking to me and suggested I look at something called SED tvs. Apparently these where supposed to be the next big thing. Has anyone heard of these and does anyone know what happened to them?

There was a mass of interest in SED a couple of years ago although no actual screens have ever been made available to purchase. It is now primarily Canon who are supposedly continuing development of this screen technology, although there have been rumours that Sony are interested in the technology for broadcast specification monitors (LCD and plasma just aren't accurate enough on virtually every parameter). Basically the screen consists of an array of electron emitters, each of which is the equivalent of a small CRT. This brings all the advantages of a CRT screen (high contrast, wide viewing angle etc.) but with the size (and energy saving potential) of an LCD. However, the massive drop in the price of both LCD and Plasma screens is probably what has held this technology back and to be honest I wouldn't hold your breath !

I test OLED TVs for a living – and trust me, different sizes perform differently
