    OLED TV: What You Need To Know

    There is a great article in techradar that explains everything you need to know about OLED. I also added a few things below to give it more detail.

    =========
    Quotes are from techradar.

    Apart from two show-off teeny tiny TVs from Sony and LG, OLED panels have so far only been common in mobile phones, and while their future in tablets and digital cameras is assured, there's much less certainlt surrounding the super-flat tech's suitability - and, crucially, its affordability - for use in bigscreen TVs.
    Should you wait for the first OLED TV? Will they be affordable? And what are the advantages of OLED technology? Read on to find out all about the latest bigscreen buzzword.
    What's the difference between OLED and LED?
    Everything. They might sound alike, but the processes are completely different. OLED stands for Organic Light-Emitting Diode, with 'organic' referring to the carbon film that's sat between two conductors. OLED panels emit their own light when an electric current is passed through, whereas cells in a LCD display are transmissive - they require an external light source for brightness.
    Until now there's been a question mark about longevity of OLED panels, while production lines have been impossible to make profitable due to high failure rates. Clearly, that's all about to change.

    Above 2 items and the last item at the end are from howstuffworks.com

    What are the advantages of OLED?
    Gamers and home cinema aficionados are going to absolutely love OLED. Having tried it ourselves, we can vouch for the lightning-quick - and we mean it - responsiveness of the panel. It's rated at around 1,000 (some say higher) times faster than a LED-backlit LCD panel, but it's superior to plasma tech, too.
    As well as being completely devoid of blur, and so much more detailed, even during fast-moving video, light output is controlled in each pixel so very localised dimming is possible.

    How slim is OLED TV?
    The result is awesomely deep blacks and bright, peak whites, as well as improved colour accuracy - and all from a form factor that's just a few millimetres in depth, so much lighter than standard TVs. That slimness is down to sub-pixels that self-luminate, meaning no bulky backlight is needed, which in turns means more power efficiency.

    LG's OLED TV
    LG's EM9600, just 4mm thick and weighing 7.5kg is scheduled to arrive in the UK in the second half of 2012. Other than its OLED panel, it will feature Smart TV with a Dual Core processor, WiFi, Freeview HD and a Magic Remote. It is due in the second half of 2012.

    Samsung's OLED TV
    Samsung's ES9500, was produced from a single pane of glass and has voice controls galore. Samsung claims that its OLED TV's colour reproduction is 40 per cent more accurate than an LED-backlit LCD, though at 7.5mm it's also almost twice as 'fat' as LG's attempt. It's also due in the second half of 2012.

    Are Samsung and LG's OLED TVs exactly the same?
    No. Samsung uses 'Super OLED' tech while LG describes its take on OLED as the less catchy '4-Colour Pixels and Colour Refiner'. LG's take on OLED adds a fourth pixel - white - to the traditional RGB colour mix (a bit like Sharp's Quattron TVs), but also needs a colour filter. Samsung claims that it's Super OLED tech, which doesn't use a filter, is superior.

    Can OLED do 3D?
    Both are 3D (Samsung's uses Active Shutter tech, while LG is planning on using its passive Cinema 3D system) and sport Full HD resolutions, though not surprisingly, neither brand wants to blow the slim depth that OLED offers. Samsung is including a separate connections box that will also include the power supply.
    What about Sony's Crystal LED tech?
    As is normal these days, it's the Korean manufacturers that are making the biggest strides tech-wise, leaving Sony - manufacturer of the very first OLED TV back in 2007 - to bad-mouth the tech it gave commercial birth to. Instead of a conventional LED backlight, or an Edge LED array where lights are strung across the sides of a screen, Sony's Crystal LED tech (debuted at the CES as a headline-stealing 55-inch prototype) promises to be much more affordable.
    Sony Crystal LED TV
    Sony's tech sees a single ultra-fine LED attached to each sub-pixel in a Full HD panel (that's three LEDs for each pixel, and six million in total). The effect is that the TV's light source is actually in front of its pixels, though the end result is claimed to be akin to OLED - a quicker, more colourful panel boasting better contrast.
    Who else makes OLED TVs?
    Although Panasonic sold its share of a OLED subsidiary to Toshiba a few years ago, reports suggest that Panasonic is setting up a pilot production line, with the company admitting as much at CES.
    How much will OLED TVs cost?
    LG is reporting it's model around $8K and Samsung's around $9K
    What's the future for OLED?
    In the long-term the tech has a lot of promise; already there are flexible and foldable prototypes that can be rolled-up into a tube, while OLED screens will eventually appear that are so thin and transparent that they will appear invisible when not in use. Analysts at DisplaySearch predict that OLED TVs will make up grow to a mere 2.5% of the 40-inch+ TV market by 2015 due to high prices and limited availability.

    This technology is a game changer IMO. If they can get these things made with high fabrication rates, we should see massive size displays (100 inches or more) for less than $10k within the next 5-8 years. They are extremely light weight too...the 55 inch model from LG weighs under 20lbs!

    I don't think I have ever been this excited by a new product before. I wonder how long it will be before I will be able to buy a 65" TV for 4K? Viewing sports in crystal clear resolution without blurring will be awesome. Smaller size and reduced power usage as a by product.

    I wonder if this eliminates the need for projectors.

    Richard,

    I think this could eliminate projectors eventually due to the light weight of the displays. It will certainly be a game changer if they can get very large sizes at a reasonable cost per quare inch.
