Burn-in is often exaggerated, but it is still important to understand the phenomenon.
Organic light-emitting diode (OLED) televisions have revolutionized the home viewing experience. By ensuring that each pixel on your display is individually illuminated, OLED screens enhance images by providing deeper contrast, faster refresh rates and wide viewing angles. Despite these benefits, early OLED televisions came with significant drawbacks. One notable problem was known as burn-in, in which OLED displays retain images even after leaving the screen.
Burn-in is an unfortunate byproduct of OLED’s organic pixels or diodes, which are more fragile than the synthetic ones used in LED screens. OLED screens also do not use an additional light source such as a backlight for illumination. Instead, each pixel illuminates itself and turns off when not displaying color, creating more vibrant colors and deeper blacks. Although self-illumination enables better contrast ratios, it also forces each individual pixel to take more direct energy. When asked to do this for a long period of time, this causes the pixels to fade unevenly. Image retention is a ghostly relic of this uneven decline.
Burn-in is most likely to occur when parts of the display remain stationary, especially at high brightness, as hot diodes degrade faster. An obvious case would be a still picture or paused program that remains on the screen. Other common examples include television logos and chyrons, program menus, news tickers, and even subtitles. Letterboxing or black bars from the 4:3 aspect ratio can also affect the panel as those pixels will not appear distorted whereas others do. Overall, still images, when constantly on your screen, can leave their ghostly residue on your otherwise vibrant OLED display.
Is burn-in still possible?
It is important to emphasize that burn-in will not likely occur after a few hours. Rather, tests indicate that permanent burns are likely to occur only after the TV has been exposed to static elements for months or years. For example, during a long-term burn-in test from the review site RTIngsOne user noticed that the subtitles burned out after approximately 7,100 hours of viewing. In a statement given to CNETA Sony spokesperson said consumers should avoid leaving still images, such as paused video games, “on the screen for several hours or days.”
You are most likely to experience image retention from chyrons, logos, news tickers, and static elements found in video games. However, you are likely to run into problems if you watch the same television channel for hours. Thus, your uncle who spends his day yelling at Fox News may be more likely to experience burnout. However, even in extreme cases, permanent image retention is unlikely.
The important thing is that not all static elements are created equal. during RTIngsFor example, in a long-term study, testers found that “static scoreboards at sporting events do not cause any problems.” But for most consumers who use their OLED televisions to watch movies, series, sports, and other content with distinct imagery, burn-in is largely a relic of the past.
Preventing burn-in
Ultimately, preventing burn-in is largely up to the audience. However, anyone with a semi-regular viewing habit shouldn’t have much of a problem. If concerned, avoid leaving static images on your screen, lower your brightness and enable the settings mentioned above. When you start seeing faint glimpses of intact images on your display, turn off your screen and let it rest. Returning to your display, watch a few hours of regular programming. Movies, television series, and live sports should all provide ample variety. If you’re worried about your OLED computer or phone screen burning out, change your wallpaper and go to dark mode. Fortunately, burn-in remains a remote possibility for most consumers.
