What is burn-in? 4k5810
The burn-in effect, also known as screen burn, is an old enemy of televisions such as LCD and even newer models with AMOLED and OLED technologies. Not even cell phones escape, and the most affected are models from Samsung and Motorola.
But what is burn-in on OLED screens anyway? The effect is due to the continuous display of images for a long period, which configures a wear on the organic LEDs of the display of certain devices, and over time lead to their gradual crumbling.
In practical , it is enough to think of a television channel that is broadcasting the news. Pay attention to the newspaper logo, usually displayed in the lower right corner, and how the image behaves over time. It is likely that because that image has been displayed continuously for a long time, the LEDs work much faster than the others, causing greater wear on them over a long display range.
Burn-in on OLED screens can be confused with the image persistence, which has the same origin and consequences, but disappears shortly afterwards. Screen burn usually does not go away and continues for the rest of the product's life.
On cell phones, it is very common for virtual navigation buttons such as return, the open tabs menu, and home to be the most affected, precisely because they are active most of the time when using smartphones. Sun exposure can also be one of the causes of burn-in on OLED screens.
Why does burn in occur on OLED screens? 572x5o
The main explanation is directed to technology OLED. Its operation is based on a system that produces its own light, coming from an emitting material, the so-called organic LED. This material is more prone to the effect when compared to QLED technology, in which the LEDs are of the quantum dot type.
The technologies nanocell e QLED use quantum dots and make TV s a great barrier to the effect. However, the burn in effect still occurs on screens Smartphone AMOLED and while the technology for mobile device screens cannot solve this problem, there are ways to work around this defect and extend the life of your smartphone screen.
How to avoid burn-in on OLED screens? 6sa6y
Using TV on a regular basis - that is, watching movies, series, news and other audiovisual content - it is very unlikely that the occurrence of burn in throughout the life of the television. However, to mitigate its occurrence, some good practices are recommended.
- Keep the TV's original brightness settings;
- Playing video games or watching content on applications such as YouTube (which have a navigation bar and commands in a fixed position) it is recommended to decrease the screen brightness;
- Do not keep the TV or smartphone exposed to constant sunlight;
- Keep the screen saver on;
- Keep functions that prevent burn-in enabled — such as Screen Shift, Screen Saver and Pixel Refresher on LG TVs
It is important to point out that burn in is a hardware defect and not a software defect, and can only be circumvented by replacing the display of the affected device, which is generally not included in the warranty — manufacturers consider that the constant use of TVs and smartphones with still images falls under equipment misuse.
The new line of evo OLED TVs 6d3g62
During your participation in CES 2021, TVs and displays were the devices that received the most attention from LG, which announced the new line of OLED TVs evo. The first change in these new displays is in the pixel layers, where the new OLED evo will add an extra light-emitting green substrate between the two blue ones, making it easier to boost brightness and possibly extend color coverage.
The second change resides precisely in the blue substrates, which had their composition material modified, as explained by the company. LG stopped purchasing the blue OLED emitters with the Idemitsu Kosan, which produces them using Hydrogen, to buy them from DuPont, which uses Deuterium (an isotope of Hydrogen) in its composition.
Such changes show several improvements over current models of OLED televisions — among them the guarantee of eliminating the burn-in defect. For now, OLED evo displays should remain exclusive to LG's OLED G1 line, in addition to equipping TVs from other companies, while the A1 series, which is already confirmed to arrive in Brazil, B1 and C1 continue to use traditional OLED displays.
Is it worth buying devices with OLED screens? 606a3b
Short answer: yea! As we mentioned in the introduction to this article, the new models of OLED TVs currently available on the market are designed with features that change the image even if you don't realize it (screen shift), protecting against the effect of burn-in. In addition, these types of televisions have screen savers similar to those seen on computers, and they turn off when the screens are paused.
OLED TVs offer good s, more vivid colors, true blacks, higher contrast and intensity, high refresh rates, no light leakage, good for gaming — a great list of advantages over other display technologies. According to the technological specifications of the main manufacturers, the OLED has a lifespan of 100 thousand hours (11 years of use), longer than the lifespan of the competitor (QLED), which is 7 to 10 years.
OLED is currently the best technology for TV screens, with MicroLED aiming for this position for the future — although there are MicroLED screens being sold in TVs and commercial applications, limitations to the production of this type of screen allow only very high quality models to be produced. large (Samsung's smallest model comes in at 76 inches). In the meantime, OLED will continue to be the best choice for very high quality TV screens.

Excellent subject! I have a 1-inch LG OLED C48 and it's really worth it.
Come back in about 5 years and tell us if it was still worth it…
LOL
For 5 years he will have a very beautiful image, much better than this washed-up image that you must watch kkkkkk
My LG Oled TV showed burn in with only 1 e1\2 of use, which is unfortunate. I ed LG and they didn't even respond. Bad technology, bad service and horrible product. NEVER BUY LG PRODUCTS.
I make Sinval's words my own. LG OLED Disposable TV.
Unfortunately OLED technology will give problems faster. If it weren't for that, it would be my choice with my eyes closed, but unfortunately lg seems to repeat the same thing it did with smartphones. In this case, I don't advise buying OLED and I already see stores in malls dominated by Samsung QLEDs, which print a 10-year warranty against burn-in on their screens. Lg better quality, but prejudice!
Burn – in persistent in an LG 55′ oled bought for 2000,00 euro. disgraceful. Inoltre nessun aggiornamento for how much rear the SMart Tv che ormai è practically unusable. A shame. Peccato perchè era davvero un bel vedere come qualità immagine
