Here, there is also the option of doing a major “refresh” that completely removes image residue. You can set how often a refresh should be performed in the corresponding picture settings. Thus, all pixels of the OLED panel are adjusted to the weakest one. Pixel Refresh is a kind of maintenance program that activates when the OLED is turned off. This prevents very narrow things like a crosshair from burning in during gaming. This way, pixels don’t permanently display the same thing, even if it’s static content. This shifts the entire image up, down, or to the side by a few pixels without noticing. One possible function to further minimize a burn-in risk is Pixel Shift. Some functions happen in the background and the user does not notice them, while others should be performed manually at regular intervals to maintain the TV. The various manufacturers of different OLED TVs have meanwhile installed some functions and technologies in their TVs that are supposed to minimize the risk of burn-in as much as possible. The situation can be different for commercial use and long-term operation. Burn-in is not a problem in the private sector. Here, very bright parts of the image are still displayed for a short time when switching off or over, but they disappear again after a few moments. There is also the phenomenon of afterglow. Only for office use, in waiting rooms or as general display screens should OLEDs not be used. That is hardly achievable under normal use conditions. In many of these long-term tests, very bright and static pictures were permanently displayed on OLED TVs and only after more than 10,000 hours was a visible burn-in of logos or message bars detected. However, long-term tests with OLED TVs show that a burn-in risk is only theory, especially during normal use.

Therefore, you should make sure not to use the TV at maximum brightness for a long time. If very bright, static content is now displayed for a long time, there is a risk of burn-in. To preserve the durability of these pixels, they are dimmed accordingly, which results in a darker picture on an OLED TV compared to a QLED.
However, if they get too warm with very bright content, t hey can lose their lifespan very quickly. That’s why an OLED TV doesn’t have a separate backlight because the organic pixels of the panel take care of that themselves. However, the white pixels are the most sensitive here because they regulate the brightness. The risk of burn-in is no longer one nowadays. This guarantees the high color variety and accuracy. This is only possible because each pixel consists of a red, blue, green and white subpixel that lie on top of each other. Due to the WRGB pixel structure, all pixels are the same and can generate white or colored light themselves. This is how OLED TVs achieve the almost perfect black level. The abbreviation OLED stands for “organic light emitting diode” and means that each pixel lights up itself or simply turns off completely when the picture is black. This unique OLED technology delivers an incredible picture and also doesn’t need a backlight compared to the LED panel.

OLED TVs are known for displaying near-perfect blacks and brilliant colors, which is why they are incredibly popular, especially among movie and series fans. But why are OLED TVs in particular affected by the problem? Burn-in on OLEDs However, the risk only exists if the TV always displays the same content for a very long time.Various long-term tests have already shown that devices have to display the same content for more than 10,000 hours for burn-in to occur. While the former still have to deal with the burn-in risk, QLED models work with backlighting and therefore do not have to deal with this problem.īurn-in means that static content in particular, such as TV logos or the headline bars at the bottom of the screen and on the right of news channels, are permanently burned in, leaving a permanent shadow in the picture. OLED and so-called QLED TVs now dominate the sales market. This durability problem not only kept customers away from the products, but also forced manufacturers to reorient. Image burn-in is not a new phenomenon after all, the issue already existed in the days of plasma-based TVs. It is one of the most discussed topics regarding OLED TVs: the burn-in risk. But even with the new, much brighter OLED TVs from LG, Sony and Panasonic, the fear of burn-in still remains, or does it? We have summarized the most important information about the polarizing topic for you here. OLED TVs are very popular and could replace LCD-LED devices in the future.
