Over recent years, we have seen massive advances in technology, and none more so than in the home entertainment scene.
If you look back over the past 50-60 years, our televisions have undergone a massive change. The evolution from the black and white box, through to color CRT tv’s, Plasma and LCD’s to the latest incarnation- LED LCD.
The next step step in the evolution is OLED TV.
OLED’s are not a new technology. OLED’s have been used for a number of years in smaller electronic devices such as mp3 players, watches, mobile phones and PDA’s.
The question that a lot of people will be asking is what are OLED’s and what are they doing in our televisions.
OLED stands for ‘Organic Light Emitting Diode’
OLED’s are similar to standard LED’s used in televisions today. The difference is the way in which light is produced. In Organic LED’s, the electroluminescent layer is made of organic compounds. In layman’s terms- as the electricity passes through this layer, it emits light. the frequency of this electricity determines the color produced.
Some of the advantages of OLED TV’s:
Better Power Efficiency.
While standard LCD TV’s filter the light coming from a back light, allowing only a small amount of light to pass through, creating truer blacks and reducing the power required to operate the TV. OLED’s take this one step further. As they have no back light, the power consumption is drastically reduced, resulting in a very cost effect product with truer colors.
Response Time/Refresh Rate.
LED TV’s currently have a response time of 2-8ms (refresh rate of 200Hz). OLED’s have a response time of 0.01ms, offering a refresh rate of 100,000Hz. A faster refresh rate means that sports and fast movement is done with crisper images.
Truer Colors.
Unlike Plasma’s, LCD’s and LED LCD TV’s, OLED TV’s don’t have back lights. Back lights are used to produce the picture on your tv screen, the use of these back lights creates heats and uses quite a bit of power (with the exception of LED LCD’s). OLED TV’s have no need for this back light as the light is produced by the OLED themselves. This results in blacker blacks, truer colors, drastically cheaper running costs and no heat.
OLED technology brings Hollywood Sci-Fi to the real world.
OLED’s offer flexibility not seen before on electronic displays. OLED’s are able to be created on translucent layers. This allows for the creation of screens and displays that are see through, like windows. 
Because OLED’s can be created extremely thinly (as thin as .3mm thin). It may be possible in the future to have a TV that you can roll up! That way when you want to watch the TV, you just have to unroll your TV!
As OLED technology becomes more common, the technology will continue to develop and more importantly for us, the consumer, prices will come down, making OLED TV’s much more affordable.
OLED TV’s are expected to hit the stores mid 2012. This will begin the start of a powerful new era of Home Cinema Entertainment.
