As technology advances, display screens have become an integral part of our daily lives. From smartphones to TVs, the quality of the display can significantly impact our viewing experience. One of the most popular display technologies used in modern devices is AMOLED (Active Matrix Organic Light-Emitting Diode). While AMOLED screens offer excellent color accuracy, contrast, and energy efficiency, they are not immune to issues like burn-in. In this article, we will delve into the world of AMOLED burn-in, exploring its causes, symptoms, and prevention methods.
What is AMOLED Burn-In?
AMOLED burn-in, also known as image retention, is a phenomenon where a static image is permanently etched into the display screen. This occurs when the same image is displayed for an extended period, causing the organic material in the OLED panel to degrade. As a result, the affected area may exhibit a ghostly impression of the original image, even when the screen is displaying different content.
Causes of AMOLED Burn-In
Several factors contribute to AMOLED burn-in:
- Prolonged display of static images: Leaving the same image on the screen for an extended period can cause burn-in. This is particularly common in scenarios where the same image is displayed repeatedly, such as video game menus or TV channel logos.
- High brightness settings: Operating the display at high brightness levels can accelerate burn-in. This is because higher brightness settings increase the voltage applied to the OLED panel, leading to faster degradation of the organic material.
- Low pixel refresh rates: Displays with low pixel refresh rates are more prone to burn-in. This is because the pixels are not being refreshed frequently enough, allowing static images to persist for longer periods.
- Aging of the OLED panel: As the OLED panel ages, its susceptibility to burn-in increases. This is due to the natural degradation of the organic material over time.
Symptoms of AMOLED Burn-In
Identifying AMOLED burn-in can be challenging, especially in its early stages. However, there are some telltale signs to look out for:
- Ghostly images: A faint, ghostly impression of a static image may appear on the screen, even when displaying different content.

What is AMOLED burn-in and how does it occur?
AMOLED (Active Matrix Organic Light-Emitting Diode) burn-in, also known as image retention, is a permanent ghostly impression of an image that remains on a screen even after the image has changed or disappeared. This phenomenon occurs when an AMOLED display is subjected to static images or patterns for an extended period, causing the organic material in the pixels to degrade unevenly. As a result, the affected pixels may become less responsive or even permanently damaged, leading to a visible ghostly impression of the original image.
The likelihood of burn-in increases when the same image is displayed for a prolonged period, such as when a phone is left on the same screen saver or when a TV is displaying the same channel logo or menu. Additionally, factors like screen brightness, image contrast, and display settings can also contribute to the risk of burn-in. However, it’s worth noting that most modern AMOLED displays have features to mitigate burn-in, such as pixel shifting and image retention compensation.
What are the symptoms of AMOLED burn-in?
The symptoms of AMOLED burn-in can vary in severity, but common signs include a faint ghostly impression of an image, a permanent shadow or outline of a previous image, or a noticeable discoloration of the affected area. In some cases, burn-in can also cause a decrease in screen brightness or an uneven color representation. If you notice any of these symptoms, it’s essential to take preventive measures to minimize further damage.
It’s crucial to distinguish between burn-in and image retention, which is a temporary condition that can be resolved by displaying a different image or turning off the screen. If the ghostly impression persists even after displaying different content or turning off the screen, it may be a sign of burn-in. In severe cases, burn-in can be permanent and irreversible, so it’s essential to address the issue promptly.
How can I prevent AMOLED burn-in on my device?
To prevent AMOLED burn-in, it’s essential to take proactive measures, especially if you use your device for extended periods or display static images frequently.
