Infos about OLED-Television

OLED TVs work by using a new display technology that is called OLED which is short for Organic Light Emitting Diodes. Those self-emitting diodes create real colors, perfect contrast and motion clarity for a picture that is almost blur-free and better than any other created by other technologies. The panels of OLED TVs come with thousands of organic LED pixels that display images that are richer and brighter than those of current LED TVs. Pictures of OLED TVs are amazingly clear and bursting with rich color. They are nothing like you have ever seen.

How does an OLED-TV work?

In order to produce OLEDs thin films of organic materials are placed between two conductors. When electricity is applied, a bright light is emitted. Unlike LCD OLED doesn’t need a backlight to emit light. Each independently working diode is a pixel. For this and more reasons OLED TVs have several advantages over LCD TVs:

  • The refresh rate is faster.
  • Contrast and color reproduction are better.
  • The panels are thinner and lighter: Some of the thinnest OLED TV panels do only weight 3,5 kg and are only 4mm thick, while some prototypes top that by being  merely 0,3 mm thick.
  • With almost 180 degrees the viewing angle is better.
  • OLEDs are easy on the environment for they draw less power and contain no toxic metals.
  • OLED panels offer more options for they could also be flexible and/or transparent.

Arguments for an OLED TV

Exceptional OLED Picture Quality:
OLED TVs do not only produce colors that are natural and brighter but also allow wider viewing angles. Therefore the viewing experiences are enhanced dramatically. Because this display technology naturally refreshes up to a thousand times faster than LCD technology the frames are sharp and each detail pops! The OLED color gamut can exceed NTSC standards. Last but not least absolutely noteworthy are the viewing angle of almost 180 degree and an inherent contrast ratio that is bigger than 1.000.000:1.

Authentic colors:
OLED TVs have a color palette that is richer and more authentic than that of current LED TVs. The colors that OLEDs produce are simply vibrant and gorgeous.

Incredible contrast:
Especially during dark scenes the stunning contrast is delivering a truly cinematic experience.

Virtually blur-free:
Whether subtle motion or fast-paced action – any movement on the screen is virtually blur-free.

Thinner and lighter:

Right now you can by panels that are only 4mm thick at 3,5 kg, whereas some prototypes aren’t thicker than 0.3 mm.

Ecologically friendly:
The self-emitting OLEDs draw less power and work without toxic metals.

More possibilities:
Potentially, OLED TVs could be flexible and/or transparent in the near future.

Samsung brought out their first OLED TV, the KN55S9C – a 55″ curved Full-HD set, in August 2013. Thanks to the curved panel the distance from the viewer to the TV screen is the same from almost any angle which reportedly allows a better viewing experience. The OLED TV comes with Multi-view, a feature enabling users to watch two different 2D programs using active-shutter 3D glasses. Its compatibility with Samsung’s Evolution Kit ensures that the TV is future-proofed. It weighs 27 Kg and is 5.3 inches deep. In US and South Korea you can purchase this TV for approximately $ 8.900.

The flat 55’’ OLED TV that Samsung also developed probably won’t be released as a commercial product any time soon. It was first branded as “Super OLED TV”, but is called “Real OLED TV” by now. That change might base on the fact that Samsung are, unlike others, using ‘True OLED’ RGB subpixels and like to differentiate its OLED TVs from LED TVs.

LG Electronics Display:

In December 2011, LG announced that they would bring out their first commercial OLED TV, the 55″ 55EM9700. Little more than a year later, in January 2013, the TV launched the Korean market at a price of about $ 10.000. It was also released in the UK. The Full-HD panel features 100.000.000:1 contrast ratio and fast response time (according to LG, 1.000 times faster than LCD). With a thickness of only 4mm and a weight of just 3,5 kg that panel is the thinnest and lightest at the moment. To LG OLED is the “ultimate display technology”. LG use there WOLED technology

At the IFA-2013 LG showcased the world largest panel with 77 inch and 4K Ulhtra HD resolution. This device was only a prototype and not to buy at the moment.

Sony introduced the world’s first 56 inch OLED TV with a 4K (3840×2160) pixel resolution at the Consumer Electronics Show in Las Vegas in 2013. It was developed in a partnership with AU Optronics Corp. (AUO). The 4K resolution is achieved by using the latest oxide semiconductor TFTs and Sony’s Super Top Emission technology. This TV is still a prototype for light is forced through the OLED layer and OLED TVs use low-temperature polysilicon (LTPS) thin-film transistors (TFTs). However, some challenges had to be faced in manufacturing such a large OLED display.

The 56 inch OLED panel with 4k2k resolution (3,840 x 2,160 resolution, 8,29 million pixels) that Panasonic developed is the world’s largest OLED panel produced through the “RGB all-printing method.” The prototype was presented at the Consumer Electronics Show in Las Vegas in 2013. Sony and Panasonic have decided to stop their OLED-Tv development, the goal was to combine Panasonics printing organic material technology with Sonys Super Top Emission technology. But both companies fail because they did not reach the goal because because of the production costs.

OLED TVs of the past

LG’s 55’’ OLED TV isn’t the first OLED TV that is launched. Already in December 2007 Sony started to sell the XEL-1, which was more of a technology prototype than a commercial set and only produced in small quantities. With only 11’’ it was a small TV and rather expensive at a price of around $ 2.500. But LG offered a similar device, too. The 1,7 mm thick 15’’ EL9500 OLED TV was also more of a technology demonstration and at prices of $ 2.600 in Korea and € 1.999 in Europe very expensive as well.

True Pixel vs WRGB

In order to create each ‘pixel’ the basic OLED TV design uses 3 color OLED sub-pixels (RGB: Red, Green and Blue). It is referred to as a direct emission OLED (or SBS, side-by-side). Samsung is using this design in their small displays and in their upcoming Super OLED TVs. Other companies are using WRGB (or WOLED-CF), which is an architecture working with four white OLED subpixels with color filters on top (RBG and W).

It was Kodak who developed the WRGB technology, while the IP is now owned by LG Display. It was meant to make the OLED panel easier to produce, yet it is less efficient. The OLED TVs that LG Displays is going to release will base on this design.

OLED TV history

  • Both Samsung and LG offer 55’’ curved OLED TVs. But the production capacity is low and the prices for the devices are still high. Samsung’s KN55S9C is at a price of $ 8.997 a little cheaper than LG’s 55EA9800 that costs $ 9.999. Both 55’’ panels feature Full-HD resolution and got spectacular reviews. All reviewers said that OLED TVs are offering the best picture quality ever.
  • LG are offering two kinds of flat 55″ OLED TVs. They are both using the same WRGB Full-HD panel. The Gallery OLED TV is produced for Europe and costs  € 8.999 while the 55EM9700 ships in the US and many other countries.
  • In September 2013, LG introduced a 77’’ curved UHD (4K) OLED TV prototype. It is the largest OLED panel that has ever been shown.
  • Sony and Panasonic are cooperating on the OLED TV technology. The both presented 56″ 4K OLED prototypes at the Consumer Electronics Show. Panasonic plans to convert its LCD fab to OLED.
  • AU Optronics plans to start producing samples of its active OLED TV program soon. They helped to produce Sony’s 56″ 4K OLED prototype.
  • It is known that Seiko Epson are working on inkjet printable OLED TV panels. The state of that research is unknown though.
  • DuPont announced that a leading OLED fabricant has licensed their nozzle-printing technology in order to make OLED TV panels that are cheaper for they are printed.
  • Back in 2007 Sony introduced the world first commercial 11 inch XEL-1
