OLED displays are known for their stunning picture quality, deep blacks, and vibrant colors. However, one issue that has plagued OLED screens is burn-in. Burn-in occurs when a static image is displayed for too long, causing the pixels to degrade and leaving a permanent ghost image on the screen.
Here’s what you need to know about OLED burn-in and how to prevent it on your TV, phone, and other devices.
What Causes OLED Burn-in?
OLED burn-in occurs when a static image is displayed on the screen for a prolonged period. This can be caused by leaving the same channel or logo on the screen for hours or days, or even leaving a paused video on the screen for too long. As the pixels degrade, they may start to display the ghost image even when the screen is displaying a different image.
How to Prevent OLED Burn-in
Fortunately, there are several ways to prevent OLED burn-in. One way is to avoid displaying static images for extended periods. For example, you can vary the content you watch on your TV, switch channels or streaming services frequently, and avoid leaving paused videos on the screen for too long.
Another way to prevent burn-in is to use screen savers or automatic power-off features that turn off the display after a certain period of inactivity. Some devices, such as smartphones, have built-in features that prevent static images from being displayed for too long by shifting them around the screen slightly.
Manufacturers are also implementing technologies to reduce the risk of burn-in on OLED displays. For example, LG uses a feature called Pixel Refresher that automatically runs pixel calibration routines to reduce the risk of burn-in. Samsung’s QLED displays also have a feature called Burn-in Reduction that shifts static images to different parts of the screen to prevent burn-in.

While OLED burn-in is a real issue, there are several ways to prevent it from occurring. By avoiding prolonged display of static images, using screen savers or automatic power-off features, and taking advantage of manufacturer technologies that reduce the risk of burn-in, you can enjoy the benefits of OLED displays without worrying about permanent damage to your screen.
