Oled-TVs - what is this? Oled-TV: prices, overview

In our time, technical progress is developing very rapidly. For example, about 20 years ago in our country, very few people knew about the existence of a computer. Now the PC is almost in every house. Every day there are new gadgets, and old technologies are being modernized.

So, relatively recently (in March 2013), Oled-TVs began to spread actively. What it is? This is what we will talk about in this article. We will take a closer look at the features of this modern technology, let's talk about its advantages, disadvantages, etc.

Oled technology

To begin with it is necessary to say a few words about the technology itself. Oled (from English organic light-emitting diode) is a special technology based on a semiconductor device made of special organic compounds. These compounds are able to actively emit light if through them to pass an electric current. The fact that organic materials are capable of electroluminescence (non-thermal glow, which is excited by electricity) was recognized as far back as the 1950s. The discovery was made by the French scientist Andre Bernanoz.

But how is this technology used in TVs? What are the remarkable Oled-TVs? What it is? About this and many other things you can read in this article.

Oled-TVs: what is this?

Old technologies can be found in the modern world. A great example of this is Oled-TVs. What is it and what does it eat? Answers to these questions can be found here.

A characteristic feature of Oled-TVs is a matrix in which the main functional elements are organic light-emitting diodes. That is, in these TVs, organic elements are combined with electronics. Passing the electric discharge through natural connections, get a bright glow. And using phosphors you can get a quality glow of any color.

In theory, this sounds very good, but how is everything in practice? In fact, TVs with Oled-screen have a lot of advantages, which we'll talk about below.

Positive features

Perhaps the first and most important advantage is the incredibly high brightness and contrast settings. Organic light emitting diodes provide a wide range of luminescence. Thanks to them, you can adjust the brightness from the minimum values (for comfortable operation at night) and ending with an amazing brightness of up to 100 thousand cd / m ² . As for the contrast, the Oled-TV can get a phenomenal level of 10 million to 1. Of course, for other televisions such indicators are unattainable.

Another advantage is compactness. Oled-TVs have very small dimensions and weight. Again, all thanks to the same organic LEDs that have a delightful electroluminescence. Because of this, there is no need for lighting at all. Accordingly, without illumination, a lot of space is saved in the case.

In addition, unusual LEDs allow manufacturers to produce new matrices that have a very large viewing angle. This means that the Oled-TV can be viewed from any angle and the image quality will remain the same without any distortion. This feature is surely useful to those who like to watch movies in the family circle or in a large company of friends.

Also worth noting is that the matrices for Oled-TVs have a delightful response time. Even in the most dynamic scenes or with a sharp change of scenery, you will not notice an inertial trace, which is directly related to a large response.

Finally, it is worth mentioning about the cost of electricity. For a time there were rumors that Oled-TVs are very hungry and require a lot of electricity. However, everything turned out to be quite the opposite. Oled-TVs eat at times less energy than the same LCD.

disadvantages

In addition to the benefits of Oled-TVs have disadvantages. Perhaps the main disadvantage of this device is fragility. Organic light-emitting diodes can not boast of a long service life. Red and green LEDs can work tens of thousands of hours (a pretty decent figure). The main problem is that the blue LED works about 18 thousand hours (something about two years). At the moment, active development of long-life LEDs is underway. In the meantime, buyers are forced to enjoy a delightful image for only a couple of years, and then watch a distorted picture.

Another drawback, which does not allow many to buy an OLED TV, is the price. If you compare with Led-TVs, Oled-models are characterized by a sky-high price. After all, the most interesting thing is that everything should be the other way around. In theory, the production of Oled-displays is much less expensive. And this means that TVs on organic light-emitting diodes should be cheaper than liquid-crystal ones. But why in practice is everything completely different? The thing is that the production technology of Oled-displays has not been fully mastered yet. This, in turn, leads to a significant rise in price.

Should I buy an Oled TV?

Here everything is purely individual. Of course, it's best to wait a couple of years. As it was written at the very beginning of the article, the technologies develop very quickly. And this means that in the next few years the main shortcomings of Oled-TVs will be corrected and the technology will begin to spread massively. It is better to wait a year or two and get a quality product than to purchase an optimized and raw instrument now.

Best Oled TVs

If the above did not convince you and you are ready to pay huge money for one of the first to try out a new technology, then let's consider the best models of Oled-TVs from various companies.

At the moment, there are very few companies that produce Oled-TVs. This is due to the fact that huge financial resources are needed to develop a new technology. Accordingly, such TVs can be produced only by large companies like Samsung or LG. We will now talk about their products.

Oled-TV Samsung

Samsung KN55S9CAFXZA - a delightful representative of Oled-TVs from Samsung. The diagonal of the screen is as much as 55 inches. In combination with the new technology it will give a delightful picture. It's also worth to say a few words about a special function called Smart TV. Televisions of the current generation are controlled by voice or gestures. Thanks to this, the management has become much more responsive and convenient. In addition, Samsung KN55S9CAFXZA has another interesting feature called Smart Dual View. Thanks to this mode, you can watch 2 TV programs on the same TV at the same time. The new model improved the browser. Now you can chat on social networks or watch videos on YouTube without any delay. Do not forget that the Samsung KN55S9CAFXZA is also an active 3D Oled TV. Thanks to the new technology, the picture will become much more realistic and juicier. In the end, we can say that the Samsung KN55S9CAFXZA is a delightful Oled-TV. The price for it varies within the limits of 10 000 dollars.

Oled-TV LG

Model 55EA9800 - currently the best Oled-TV LG. The price for this device is about 9,000 dollars (cheaper than the equivalent of Samsung). The display diagonal is 55 inches. LG 55EA9800 has a lot of useful functions. For example, the TV supports Skype. In addition, there are standard functions like voice control, "Picture in Picture" mode, etc. Interestingly, the TV has support for 24p True Cinema. With its help, you can view movies in the quality in which they were shot (that is, 24 frames per second). Like most modern televisions LG 55EA9800 is able to connect to Wi-Fi.
