OLED (Organic Light Emitting Diode) is any LED whose emissive layer consists of a layer of organic compounds. This layer allows appropriate organic compounds to settle down in the form of rows and columns. This then makes up the pixels of different colors.
The company Matshushita has promised to release OLED television of screen size of 40 inches by 2011. This means that in just two more years, your swagger high definition television might be archaic, or at least on the roadway to extinction.

So what is the advantage to us, except that it uses organic material as the only way to generate pixel? There are many features to this new OLED television sets. They have many advantages. Firstly, they are sleek in their look and are as thin as three credit cards put together! It uses less power since it does not emit backlight. It gives long working hours for the same reason if the product is powered by battery. Furthermore, it has a contrast ratio of 1,000,000:1. This is a significant detail since it will be the first in creating deep blacks in astounding black scenes.
Also, when the OLED television is turned on, it gives a flashing fast response time compared to the current flat displays. This is due to the electric current passing through carbon. Carbon is the basis of all organic matter and OLED comprises of all the organic matter. This can also be used to finish the pollution. Carbon-based substances include wood, majority of plastics and sugar. OLED television sets can also have a lower production cost which may eventually lead to lower costs in the market. The raison d'être is that the OLED's can be printed on suitable substrate using inkjet printers or even screen printing technologies. In addition to this, the OLED substrates can be kept flexible. This opens the door to a whole new era of TV sets. Those can be roll-up displays or even displays which are embedded in fabrics. This might mean that in the coming years, our television set will be on our handkerchief!
The OLED's may seem like the perfect technology but as said, everything has subsiding disadvantages as well. The biggest problem for the OLED television is the limited lifetime of the organic materials. Blue OLED's flat displays have a lifetime of almost 14,000 hours: 5 years and 8 hours which is lower than the lifetime of a flat screen - LCD, which has a lifetime of 60,000 hours. Two of the big names in the electronic world, Toshiba and Panasonic, have supposedly come with a way to solve this problem and to push the life of an OLED television to more than that of an LCD television. This effect is achieved by the help of a metal membrane which passes the light through the substrate more efficiently. The result is the same quality of picture but with less brightness. This increases the life time as the carbon utilized is less. The effect is still yet to be checked though.
The first OLED television screen was presented by Samsung in October 2008. It was a 40 inch set with full HD resolution of 1920×1080. It had a contrast ratio of 1,000,000:1 - the max possible till now. It also had luminance of 200 cd/m2 (peak luminance of 600 cd/m2). Samsung stated that 40 inch OLED was in the international standards the largest that was currently possible. It became a market leader.
On the other hand Sony introduced the 27" OLED which was scheduled for release in the third quarter of 2009. It is said that Sony has introduced a new concept in the OLED technology by making the television even more sleek and handy. The details are yet to be revealed.
At present, this technology is used in maximum of the commercial electronic/ digital appliances such as small screen mobile phones, MP3's, digital cameras, car radio's etc. all of these are the newest need, specially for the youth, since these are handy, and easily accessible. OLED's high light output is the most favorable for the readability in the sunlight. And the low brightness level decreases the percentage of power drain.
