Quantum Dot Technology for TV’s
Quantum dots or “nanocrystals” are the new talk of the TV tech nation and many say they will soon be making their way into our homes. Last year, OLEDs were the talk of television technology and it was said they were the newest innovation in picture quality. OLEDs should have been taking the world by storm had last year’s tech gurus been correct. But, QDs are now the ones taking over.
OLEDs were played with behind the doors of many manufacturers companies. It’s true that they offer a picture quality that is truly dynamic and incredibly life-like, but after some research, TV manufactures announced that they were simply too expensive to work with and very unreliable. After this news, it became clear that OLEDs weren’t going to be making their way into everyday homes anytime soon. Quantum dots have since gained stardom and offer a more promising future.
What Is It?
A quantum dot absorbs one wavelength of color and uses it to produce another. In an LED TV that utilizes QDs, there would be a blue backlight and a layer of QDs in front. The different sizes of QDs would each produce a different color wavelength. The blue light would act as an energizer, making the tubes filled with quantum dots light up to produce a color spectrum that is rich and vibrant.
A TV that utilizes quantum dot technology would actually be rather comparable to a plasma or OLED TV in picture quality.
Who Can Use It?
Unlike OLEDs, QDs are actually rather inexpensive to work with and experts say they actually offer higher energy efficiency and greater durability than other technologies on the market today. This is a great incentive for manufactures to begin their research, and it’s expected that we will soon see full QD displays for sale.
How’s It Better?
Quantum dots were invented by Bell Labs in 1982, but they’ve just recently made their way into the television market. Since there has always been a gap between plasma screens and LED TVs, manufacturers have been looking for a better way to increase picture quality for many years. After it became apparent that OLEDs were too expensive and not durable enough to use just yet (if ever), companies shifted their focus to QDs, which may very well become the standard in the coming years. Plasma screens are slowly being phased out, and so are 1080p displays. While neither of these is going to disappear overnight, the majority of technology buffs and companies are predicting that QDs will soon be taking over the market.
QD screens provide whiter whites, more vibrant colors, and darker blacks. This produces a more life-like quality on screen.
Plasma screens offered great picture quality, but manufactures quit making them because they were large, heavy, and consumed a lot of energy. OLEDs didn’t get much of a chance in the consumer marketplace because manufacturers already spotted similar problems with the technology of an OLED TV. In search of a cost-effective and quality way to manufacture a television that provides better quality picture than most LED screens, and in hopes of making one that would compare to plasma screens without the expense and hassle, companies found quantum dot technology.
When Will It Happen?
There’s no real deadline of when the switch will happen, but it’s nearly a guarantee that in the coming years everyone will begin upgrading their sets to QD technology. The rich, vibrant picture quality will be more dynamic and extremely life-like, and it will become the standard in home entertainment technology.
In fact, LG has already announced their up-coming line of QD televisions and some models were unveiled at CES 2015 (consumer electronics show). In 2016, CES attendees can expect to see some high-quality quantum dot screens on display and it’s likely that some models will be up for sale by the end of this year.
A Change in Television?
While manufactures are still in the early stages of experimentation, there’s a very good chance that quantum dots are the answer to affordable, light weight, and energy-efficient televisions that offer picture quality comparable to plasma screens. Of course, many had made the same predictions with OLEDs last year, but so far, research regarding QD sets is looking far more promising.
With any luck, the end of the decade will see a shift in home entertainment sets, and quantum dots may very well be taking over the marketplace as early as this year.
