While many people are thinking about LCD flat screen televisions as well as plasmas, there are others that their sole job in life is to create the future of flat screen entertainment. Well sort of, because the future in flat screens is actually older technology that has been revamped. The future is already here though with companies in Japan already releasing models. It is known as an OLED, which is the acronym for Organic Light Emitting Diodes.

 

Basically in all simplicity, LEDs have been around for quite some time already; since the 1960s. However it is the OLEDs that are making some news in the industry these days.  What it is, is a thin layer or film of an organic compound which reacts to electricity. The organic compound is adhered to a polymer in rows as well as columns and the entire thing can actually be printed using current printing technology. Of course this sounds very futuristic and for many it may not seem as if it is at all possible today, but it is and production models are already available.

 

These can be used for a variety of applications ranging from televisions and computer screens to micro screens in your cell phone or even smaller. There is no need for a backlight like what the LCD screens use and the production cost is a lot smaller since it can basically be printed onto any surface. Imagine going to the department store and instead of seeing those fancy advertisements hanging from the ceiling, that they were paper thin television screens with actual animations. This is the idea behind OLED screens.

 

While all of this sounds great, you are probably thinking to your self, “What’s the catch?” Well that catch is the degradation of the organic compounds. Sure you get brighter and more vibrant colors as well as an ability to view the screen at any angle, but the compounds which light up will eventually fade and they have to be protected. Even a small amount of water, like print on a Xerox copy, will cause the screen to stop functioning in areas where the compound “smears”.

 

OLED screens have been tested and the current maximum life expectancy of any one in production is right in around 14,000 hours. This means that if you leave it on 24 hours a day the screen will 5 years 8 hours. While this may seem great, keep in mind that both plasma and LCD screens will last for 60,000 hours. Of course the OLED screens react faster then LCD (great for gamers) and they use less energy as well. The OLED is the future of flat screen viewing and soon the LCD screens will be nothing more then a thing of the past like black and white CRT screens.

Re: OLED: The future of television display

I think this was a very interesting thing to read about. I did not know the life expectancy of a LED and now knowing this, I think they would have to do something about the OLED. I could not imagine that it would not last at least 10 years or so. Many people will not be thrilled about buying a new TV once every 5 years or more. The costs would have to really come down in order for people to be happy about that.

Re: OLED: The future of television display

If the costs of producing the OLED screens is less than that of LCDs, I should think this would be a good area to watch for expansion. I'm sure as they continue to work on the technology, they will either develop ways to let the OLED be of greater durability or have the price so low as to not matter if they last longer or perhaps even both angles could be worked on. I would love to see even thinner and lighter versions of computer screens and televisions and the clarity/reaction time would be great features to have.
