Long known to TVs, the burn in effect still frightens those who will buy a TV. But, after all, how does it happen?
Did you know that the effect burn in (?Screen burn?) have different causes in each screen technology? Although he is a constant concern of those who are going to buy a TV, the current screens are increasingly more resistant to the so-called ?ghosts', As the effect is also known.
Today, most of the reports on burn in it's related to screens OLED, who use organic materials in its construction. Due to the lower durability of these displays, defects that would not be noticed on a smartphone can be seen on a TV, as they are changed and a much longer time interval.
What does Burn in?
When we display a still image for long periods of time at the same point on the screen, the effect burn in may occur. By exhibiting the same pattern of color and light for long periods of time, the pixels that make up that image can lose capacity to form other images.
This way, even if you change channels, the image retained the screen will always be partially visible. That is why this effect is also called ?ghost?.
O burn in it occurs due to different factors in each TV technology, but the effect itself is not new: it exists since tube TVs.
On the TVs of plasma, those who suffer most from the problem, burn-in occurs when the phosphor used to coat the display it takes on a permanent shape, showing marks that do not leave the screen even if you change channels.
On the screens LED and LCD, which are much less susceptible to this type of problem, the effect may still occur, because if these screens display the same images for a long time, the liquid crystal molecules may not be able to return to their 'relaxed' state anyway, in screens with LCD-LED technology, the effect is usually temporary.
There is no denying that displays OLED have properties single. Panels with this technology have better contrast, can be flexible or translucent, are much more economical than LCDs and, in addition, due to the fact that each pixel can be turned off individually – black tones are really black on OLED screens.
However, the price paid for the use of organic materials high: in addition to the degradation of OLED screens occurring more quickly, the effect burn in also more common in this type of display. What will always happen, but in the case of TVs, where the usage time ends up being bigger, the risk of having a problem also increases.
Although little used in the market, the technology of quantum dots (quantum dots) tries to solve the problems of both technologies, LCD and OLED. In these displays 'Quantum', nanometric crystals they are used to give color and light to images, bringing screens with more quality and reliability than any other type of panel.
in this future that companies like Samsung and the Sony bet for the screens. At TVs QLED, gives Samsung, have already been consecrated for their 10 year warranty against the effect burn in it is one of the highest image qualities available on the market. J's quantum technology Sony, nicknamed ?Triluminos'Was the first to appear on the market and promises to display more colors than any other TV.
Smart TVs with QLED panel
THE Samsung has a diverse catalog of models of TVs with panel QLED available in Brazil. THE Smart TV 4K QLED 55 Samsung QN55Q60RAG, for example, is the most accessible on the list. As explained above, the TV features quantum dot technology, which delivers 100% of the color volume. Like diamonds, the quantum dots are inorganic, which means bright and vivid colors for many, many years.
In addition, the line Q60 equipped with HDR 500 imaging technology, which offers much brighter than HDR Premium. For gamers, the Game Mode is automatically activated when you turn on your video game, reducing the response time to 6.8ms. Not counting the technology FreeSync, which minimizes breaks in images so you can enjoy everything with more quality.

Now, if you are looking for the ultimate technology experience QLED, the TV Samsung with 8K resolution and Upscaling the ideal option. The optimal HDR 500 of the intermediate model becomes little closer to the HDR 3000 of the QLED 8K, offering ultra-realistic and vivid colors.
With processor and AI technology exclusive to Samsung, a QLED analyzes a database with millions of images and improves any content in low resolution, transforming them into quality close to 8K. Check all the details in our release article below:
Liked QLED 8K? Well, know that it won't be so cheap to invest in the Samsung. The cheapest 65-inch version is coming out R $ 18,594.00 at the official Showmetech at the Magazine Luiza.
Like any recent technology, quantum dot screens still have a prohibitive price, but I must remember that for an investment of four or more years, which is usually the useful life of a TV, it may be convenient to invest a little more mainly if you are looking for models premium.
In addition, it is worth remembering that screens OLED they are not cheap, and knowing the possible disadvantages of this technology is an important step before buying such a TV. Although they have a phenomenal image quality, it is recommended that the manufacturer offers support against this type of defect, as the burn in yes more common on screens OLED.
Now that you know how the burn in and you know the risks of the problem for each screen technology for sure it will be easier to choose a new TV. Fortunately, panels 4K and smart technologies have become increasingly common in Brazil, meaning that it is possible to find models in wide price ranges.
And you, intend to exchange your TV for Cup next year?
