In the field of image display, new display technologies can often help the human eye to obtain as much information as possible. Among many mainstream display technologies, OLED is considered to be the most promising next-generation display technology by virtue of its self-luminous, fast response, wide color gamut and other characteristics. However, as a display technology with a history of nearly 40 years, it has been criticized, and "burn-in" is undoubtedly one of them.
When the image left an irreparable afterimage on the screen, we will vividly call it "burn-in". The reason for this phenomenon is usually related to the uneven wear of the OLED light-emitting material (one is related to the aging of the driver), which leads to uneven color distribution in some areas of the screen, which seriously affects the viewing experience. Since the birth of the OLED screen, the screen burn-in phenomenon has always existed and is unavoidable and irreversible. That is to say, once the OLED screen has a "burn-in screen" phenomenon, there is no other way than to replace the brand-new screen.
At present, high-end OLED TVs on the market still cannot completely solve the "burn-in" problem. In the first half of this year, at Incheon Airport, South Korea, an OLED TV burned the screen because of the long-term display of flight information. It is reported that the equipment has been used for less than half a year; in the second half, foreign media Rtings purchased 6 OLED TVs for screen burn test, 4000 hours After that, three of the TVs had a "burn-in" problem. As an ordinary consumer, with the longing for OLED technology, he spent a lot of money to buy OLED TV, and finally only ended up with a "burn-in" result?
Although OLED screen "burn-in" is an objective fact recognized and unavoidable in the industry, OLED TV manufacturers are actively seeking various ways to reduce the occurrence of "burn-in". At present, it is common to use a software algorithm to automatically refresh the pixel panel or automatically reduce the brightness of the static logo to balance the aging of pixels. For example, Sony Corporation of Japan has added a pixel refresh function to its newly launched OLED TV, which can move pixels left and right and up and down so as not to leave an afterimage on the screen. In addition, the smart TV display usually comes with functions such as screen sleep, screen wallpaper, etc., which also reduces the "burn-in" phenomenon caused by the static image to a certain extent.
It is worth mentioning that for the OLED "burn-in" phenomenon, the major manufacturers have different policies on after-sales warranty. we consulted some of the best-sellers of OLED TV brand customer service on an e-commerce platform. LG customer service said that "burn-in is also a screen problem and will provide a three-year warranty." Sony and Skyworth all said that "burn-in is not covered by the warranty."
In addition to relying on TV manufacturers to provide limited after-sales protection, how should OLED TV users avoid the "burn-in" problem of OLED TVs in their daily use?
It must be pointed out that although the problem of "burn-in" still exists at this stage, the market and consumers do not seem to waste food because of choking. Compared with LED panels, OLED has a huge advantage visible to the naked eye in terms of color, process, and molding. If you abandon the OLED TV only because of the "burn-in" problem, then you are likely to miss a visual feast.

- First of all, pay attention to your viewing habits and try to avoid images being displayed repeatedly at the same position on the screen or displayed for too long.
- Secondly, the screen display brightness can be reduced appropriately without affecting the viewing of the movie.
- Finally, try to turn off the TV normally by pressing the power button of the remote control or TV.
