OLED – Yet Another TV Revolution?
by Adam Dunning
It was not long ago that LCD and plasma televisions changed the way in which we watched television. For years we relied on bulky CRT TVs to enjoy our favourite shows and movies. Aside from being bulky and taking up a great deal of space, these TVs were also heavy. If you needed to repair the TV, or you were in the process of moving, these TVs proved to be cumbersome to transport back and forth.
Remember these things? They’re heavy!
That was all changed when the first LCD and plasma TVs were introduced. They were much smaller and weighed a fraction of what a CRT TV did. Unfortunately, to enjoy one of these TVs you had to be prepared to spend a large sum of money. As this style of TV grew more popular, the price slowly became more reasonable. Today it is easy to walk into an electronics store and locate a new LCD or plasma TV that has a reasonable price tag on it.
It’s easy, metaphorically and physically
Now we are in for a new revolution. The first OLED TVs are entering the marketplace. Once again, there is an incredible technology available but the price tag makes it unaffordable for the majority of people. Most of the OLED TVs available today are also quite small. If you want a big-screen OLED TV, be prepared to wait at least another year for this luxury.
You might be wondering what all the hype over the OLED TV is about. Could it really be any better than LCD or plasma TVs? The answer is yes. OLED technology is quite impressive and it is certainly the way of the future. Instead of replacing CRT TVs with LCD and plasma TVs, it’s time to replace your LCD and plasma TV with an OLED TV.
This is OLED. Cool huh?
OLED technology is certainly not something new. Kodak was the first company to begin working with the technology during the 1980s. It was not long before other electronics companies such as Sony and Panasonic were working to improve the technology.
OLEDs, or Organic Light Emitting Diodes, function as a solid-state device. This means that they are not susceptible to the burnout that other televisions are often confronted with. OLEDs are essentially a collection of organic molecules that can be produced in extremely thin sheets. When electricity is applied to these sheets, the OLED molecules light up.
Image lag has been a problem for both LCD and plasma TVs since their debut. OLED TVs help to overcome this problem. OLEDs are more responsive to the signals they receive which means the picture on your TV is updated much quicker. This type of technology also provides a brighter picture than LCD or plasma technology can as well.
One of the most remarkable features of OLED TVs is their size. Take a trip to your local electronics store and see if you can’t locate an OLED television on display. This type of TV can be manufactured in extremely thin sizes. Your LCD television might be thin compared to a CRT TV, but if you place it next to an OLED TV you will find it to be fairly thick.
Unlike LCD TVs, OLEDs do not need a backlight in order to function. The individual molecules are able to produce light on their own. Without the need for a backlight, the overall thickness of the TV can be greatly reduced.
Eliminating the backlight from your television has a number of advantages. Many people will be happy to know that OLED TVs also consume less power. Owners of OLED TVs will also enjoy knowing there is one less part in their TV that might wear out or break one day.
They’re greener, which is just one benefit
The thin sheets of material that your OLED TV is made out of are also flexible. This material is also tolerant of a wider range of temperatures which makes this type of TV suitable for harsher environments as well. The flexibility of the material has led some people to speculate that OLED TVs will one day be foldable.
Both LCD and plasma TVs are harder to produce than OLED TVs. It is thought that as the OLED technology progresses, it will be easier to accommodate the growing demand for this type of TV due to the simplified production process. This will also likely contribute to a more budget friendly price in the future as well.
The cost of an OLED TV is easily one of its biggest downfalls at the moment. While production is simplified, it still costs a great deal to construct an OLED TV. Eventually the manufacturing process will improve but until then, expect the price to remain high on this luxury TV.
If you do decide to purchase an OLED TV in the near future, make sure to keep liquids far away from it. This type of television can’t handle any contact with liquid. Perhaps one day they will design a waterproof housing for OLED TVs but as of now they have not.
Keep them away fro this stuff!
Also keep in mind that one of the limiting factors for the lifespan of an OLED TV is its blue molecules. The red and green molecules that make up the OLED film can last up to 230,000 hours. The lifespan of blue molecules ranges as low as 14,000 hours. Once your blue molecules have failed, the TV will not be as fun to watch. It is thought that this limiting factor will be refined in the months ahead.
Making the decision to upgrade to an OLED TV will be especially painful for anyone who has recently purchased an LCD or plasma TV. If you want a TV that you can mount on your wall, OLED TVs should be at the top of your list. With their thin profile, an OLED TV will look like nothing more than a framed photograph on your wall!  As with anything, there are pros and cons to owning an OLED TV. The TV industry certainly seems geared in this direction as there is so much promise in the technology.
