OLED technology brings superior picture quality with perfect blacks and infinite contrast, but there is still a potential problem known as burn-in. Even with newer models, including modern OLED TVs, displaying static content for long periods of time can lead to permanent “shadows” on the screen.
Burn-in occurs when certain pixels display the same bright content for a long time, while the rest of the image changes. Such pixels wear out faster, leading to an uneven display. Although newer panels are more resistant, the risk is not completely eliminated.
OLED burn-in: how to prevent it
That is why manufacturers install protective mechanisms, but they are often not activated or users are not aware of their importance.
First the key adjustment is Pixel Shift (or Screen Shift). This function slightly shifts the entire image by a few pixels at regular intervals. The shift is imperceptible, but it prevents static elements like channel logos or game interfaces from staying in the same place and wearing out the panel unevenly.
The second one an important option is the brightness control of static elements, known as Logo Luminance Adjustment or Static Brightness Limiter. The system recognizes bright, static parts of the image and automatically darkens them slightly. This directly reduces the stress on the pixels without affecting the rest of the display.
The third and perhaps the most important function is automatic Pixel Refresh or Panel Refresh. This is the process of “refreshing” the panel that starts in the background, most often when the TV is in standby mode. The system then evens out pixel wear and restores brightness uniformity.
There are two levels of this process: shorter cycles that are triggered after a few hours of use, and deeper cycles that are activated after a longer period of operation or manual activation. OLED panels are without a doubt technologically advanced, but they require proper adjustment. By activating these three options, you practically eliminate the real risk of burn-in effect and ensure long-term picture quality, writes Tom’s guide.
