I’ve heard of a TV development called 4x that is said to be four times better than HD. Is OLED one and the same thing or is a parallel or different format?
-
What you’re referring to is 4K – it’s basically 4x HD resolution. It’s not the same as OLED, though in theory an OLED TV could also be a 4K TV. There are few 4K TVs at the show – we’ll be posting details soon. Like OLED, it’s very much ‘forward looking’ – nothing normal consumers need to worry yet.

There’s no reason why you couldn’t have a 4K OLED TV. That would be quite special. I think 4K TVs are likely to have a place, more immediately, in the medical and photographic world, rather than in our living room. Although one benefit I could see of 4K in the living room could be the ability to zoom in on a programme as it plays.

mccolganMy mobile phone (Samsung Tocco Ultra) has a OLED screen. The resolution and colours are fantastic. It’s about 3 years old now and I’ve had no inclination to upgrade my phone even although it’s not a “smartphone”. (I can last a few hours without interwebbythingy connection)

I’m wondering when we will see S.E.D. and F.E.D. displays? I may be wrong but I believe these are essentially thin panel CRT displays where each sub-pixel is powered by its own tiny nano sized cathode ray tube. If I got all that right I think these future televisions will have brought us back around full circle and will kick anything else including all your LCD’s, LED’s, OLED’s, and even Plasmas into touch. Maybe we will have then finally realised that the old CRT television despite its size really did give superior picture quality to anything that we now see in the high street at present?

now they have to match it with a wireless sound system. No power cords either. maybe a rechargeable or wireless power system i seem to recall seeing on a tech demo on tv. i can’t wait until it’s cheap enough to panel a whole room, my own holo-deck. I could actually feel like i was in the queen vic on eastenders. “geezer, geezer, sorted, innit”. ;-)

What is OLED TV? [Video]
OLED TVs have been a key trend at this year’s Consumer Electronics Show (CES) and are said by some to be the future of TV viewing. In this video we ask what OLED is and how it compares to LCD, plasma and LED TV technology.
OLED stands for Organic Light Emitting Diode. Both Sony and LG have launched OLED TVs to market before in the UK, however they were only 11- and 15-inch models respectively.
Sony, since showing off a 27-inch OLED prototype a few years ago, seems to have withdrawn itself from the OLED race, and it’s Samsung and LG that has taken up the baton. At this year’s CES, both Samsung and LG have unveiled 55-inch OLED TVs that are due to launch this year.
What are the benefits of OLED TVs?
OLED TVs offer superior picture quality. The colours are brighter and richer, and blacks are deeper. This is due to the improved localisation of light emission, as each organic cell that sits behind the TV’s panel can create its own light source, or none at all – depending on what the overall image requires of it.
What this means is that light doesn’t spread into unwanted areas and either lighten spots that should be dark or interfere with other colours.
Motion also seems to be handled better and power consumption is claimed to be lower, although our definitive verdict on picture quality and energy use will be reserved until we’ve had an OLED TV into our labs for a closer inspection.
Other benefits of OLED are that the panels can be made very slim and light. The 55-inch LG model on show at CES is just 4mm thick and weighs 7.5kg.
What are the downsides to OLED TV?
The two OLED TVs mentioned earlier that have already launched in the UK were both very expensive, and the 55-inch models coming to our shores later this year are likely to be priced nearer to £10,000 than to £5,000.
The initial pricing will put most consumers off, however LG believes that by 2016 the prices will be inline with that of LED TVs. One other concern about OLED TV panels is their lifespan, which has always been thought to be much shorter than that of today’s TVs. Hopefully LG and Samsung have addressed this potential OLED longevity issue.
