In this article, we will delve into the world of OLED TV burn-in, exploring what it is, how it occurs, and what manufacturers are doing to mitigate this issue.
What is OLED TV Burn-In?
Burn-in, also known as image retention, is a phenomenon where a static image is permanently etched into a display panel. This can occur when the same image is displayed for an extended period, causing the organic material in the OLED panel to degrade and create a ghostly impression of the image. Burn-in can be temporary or permanent, depending on the severity of the issue.
How Does Burn-In Occur in OLED TVs?
Burn-in occurs in OLED TVs due to the unique characteristics of the organic material used in the display panel. When an image is displayed on an OLED TV, the organic material emits light to create the colors and patterns. However, if the same image is displayed for an extended period, the organic material can start to degrade, leading to a permanent impression of the image.
There are several factors that contribute to burn-in in OLED TVs:
- Static images: Displaying static images, such as video game menus, TV channel logos, or computer desktops, for extended periods can cause burn-in.
- High brightness: Displaying images at high brightness levels can accelerate the degradation of the organic material, leading to burn-in.
- Low pixel refresh rate: OLED TVs with low pixel refresh rates can be more prone to burn-in, as the pixels are not being refreshed quickly enough to prevent degradation.

What is OLED TV burn-in and how does it occur?
OLED TV burn-in, also known as image retention, is a phenomenon where static images are permanently etched into the screen, causing ghostly impressions to remain even after the image has changed. This occurs when the same image is displayed for an extended period, causing the organic compounds in the OLED panel to degrade unevenly.
The likelihood of burn-in increases when the same image is displayed at high brightness levels for a prolonged period. This is because the organic compounds in the OLED panel degrade faster when exposed to high levels of energy. However, most modern OLED TVs have features to mitigate burn-in, such as pixel shifting and image retention compensation.
Is OLED TV burn-in a widespread problem?
OLED TV burn-in is not as widespread as it was in the early days of OLED technology. Modern OLED TVs have implemented various features to minimize the risk of burn-in, such as pixel shifting, image retention compensation, and logo luminance adjustment. These features help to reduce the likelihood of burn-in by subtly moving the image, adjusting the brightness of static areas, and reducing the luminance of logos.
While burn-in is still possible, it is relatively rare and usually occurs in extreme cases, such as displaying the same image at maximum brightness for an extended period. Most users will not experience burn-in in normal viewing conditions. However, it is essential to follow the manufacturer’s guidelines for usage and maintenance to minimize the risk of burn-in.
How do OLED TV manufacturers prevent burn-in?
OLED TV manufacturers have implemented various features to prevent burn-in, including pixel shifting, image retention compensation, and logo luminance adjustment. Pixel shifting subtly moves the image to distribute the energy evenly across the panel, reducing the likelihood of burn-in. Image retention compensation adjusts the brightness of static areas to prevent degradation of the organic compounds.
Logo luminance adjustment reduces the brightness of logos and other static elements to minimize their impact on the panel. Some manufacturers also offer features like pixel orbiting, which moves the image in a circular motion to distribute the energy evenly. Additionally, some TVs have a “pixel refresh” feature, which briefly flashes a white screen to reset the pixels and prevent burn-in.
