AMOLED (Active Matrix Organic Light-Emitting Diode) displays have become increasingly popular in recent years due to their vibrant colors, high contrast ratio, and energy efficiency. However, one of the major drawbacks of AMOLED displays is the risk of burn-in, also known as image retention. Burn-in occurs when a static image is displayed on the screen for an extended period, causing the pixels to degrade and leaving a permanent ghostly impression. In this article, we will explore the causes of AMOLED burn-in, its effects, and most importantly, how to get rid of it.
What Causes AMOLED Burn-in?
Before we dive into the solutions, it’s essential to understand what causes AMOLED burn-in. The primary reason for burn-in is the degradation of the organic material used in the display. When a static image is displayed on the screen for an extended period, the pixels in that area are subjected to constant stress, leading to a reduction in their brightness and color accuracy. This degradation can be accelerated by various factors, including:
Static Images
Static images, such as logos, icons, and menus, are the most common cause of burn-in. When these images are displayed on the screen for an extended period, they can leave a permanent impression on the display.
Brightness and Contrast
High brightness and contrast settings can also contribute to burn-in. When the display is set to high brightness and contrast, the pixels are subjected to more stress, leading to faster degradation.
Viewing Angles
Viewing angles can also play a role in burn-in. When the display is viewed from an angle, the pixels are subjected to more stress, leading to faster degradation.
Effects of AMOLED Burn-in
AMOLED burn-in can have a significant impact on the display’s performance and overall user experience. Some of the effects of burn-in include:
Image Retention
The most noticeable effect of burn-in is image retention. When a static image is displayed on the screen for an extended period, it can leave a permanent ghostly impression on the display.
Color Shift
Burn-in can also cause a color shift, where the affected pixels display a different color than the surrounding pixels.
Reduced Brightness
Burn-in can also reduce the brightness of the affected pixels, leading to a decrease in the overall brightness of the display.
How to Get Rid of AMOLED Burn-in
While burn-in can be a significant problem, there are several ways to get rid of it. Here are some methods to help you remove burn-in from your AMOLED display:
Pixel Shifting
Pixel shifting is a technique used by some display manufacturers to reduce the risk of burn-in. This technique involves shifting the pixels slightly to distribute the stress evenly across the display.
Image Retention Compensation
Some displays come with image retention compensation, which involves adjusting the brightness and color of the affected pixels to compensate for the burn-in.
Screen Savers
Screen savers can also help reduce the risk of burn-in. By displaying a moving image or a blank screen, screen savers can help distribute the stress evenly across the display.
Adjusting Display Settings
Adjusting the display settings can also help reduce the risk of burn-in. By reducing the brightness and contrast, you can reduce the stress on the pixels and prevent burn-in.
Using a Burn-in Fixer App
There are several burn-in fixer apps available that can help remove burn-in from your AMOLED display. These apps work by displaying a series of images that help to redistribute the stress across the display.
Professional Repair
In severe cases of burn-in, professional repair may be necessary. A professional repair service can replace the affected pixels or the entire display, depending on the severity of the burn-in.
Preventing AMOLED Burn-in
Preventing burn-in is always better than trying to fix it. Here are some tips to help you prevent burn-in on your AMOLED display:
Use a Screen Saver
Using a screen saver can help reduce the risk of burn-in. By displaying a moving image or a blank screen, screen savers can help distribute the stress evenly across the display.
Adjust Display Settings
Adjusting the display settings can also help reduce the risk of burn-in. By reducing the brightness and contrast, you can reduce the stress on the pixels and prevent burn-in.
Avoid Static Images
Avoiding static images can also help reduce the risk of burn-in. By displaying a variety of images or using a screen saver, you can help distribute the stress evenly across the display.
Use a Burn-in Prevention App
There are several burn-in prevention apps available that can help reduce the risk of burn-in. These apps work by displaying a series of images that help to redistribute the stress across the display.
Conclusion
AMOLED burn-in can be a significant problem, but it’s not impossible to fix. By understanding the causes of burn-in and taking steps to prevent it, you can help extend the life of your AMOLED display.

What is AMOLED burn-in and how does it occur?
AMOLED burn-in, also known as image retention, is a permanent ghostly impression that remains on a screen after displaying the same image for an extended period. This occurs when the organic compounds in the AMOLED panel degrade unevenly, causing the affected pixels to display a faint image even after the original image has changed.
The main culprits behind AMOLED burn-in are static images, such as video game menus, TV channel logos, and smartphone navigation bars. When these images are displayed for a long time, the pixels can become overused, leading to a permanent impression on the screen. However, it’s worth noting that most modern AMOLED displays have features to mitigate burn-in, such as pixel shifting and image retention compensation.
How do I know if my AMOLED screen has burn-in?
If you suspect that your AMOLED screen has burn-in, look for a faint, ghostly impression of an image that persists even after the original image has changed. This impression can be a logo, a menu, or any other static image that has been displayed for an extended period. You can also try displaying a full-screen white or gray image to make the burn-in more visible.
If you notice any of these symptoms, it’s likely that your AMOLED screen has burn-in. However, it’s essential to note that image retention is different from burn-in. Image retention is a temporary condition that can be reversed by displaying a different image, whereas burn-in is a permanent condition that cannot be reversed.
Can AMOLED burn-in be fixed or reversed?
Unfortunately, AMOLED burn-in is a permanent condition that cannot be completely reversed. However, there are some methods that can help reduce the visibility of burn-in, such as adjusting the display settings, using a screen saver, or applying a burn-in fixer app.
While these methods can help alleviate the symptoms of burn-in, they may not completely eliminate the problem. In severe cases, the only solution may be to replace the screen or the device altogether. However, it’s worth noting that most modern AMOLED displays are designed to minimize the risk of burn-in, and many manufacturers offer warranties that cover burn-in damage.
How can I prevent AMOLED burn-in on my device?
Preventing AMOLED burn-in is easier than fixing it. One of the most effective ways to prevent burn-in is to adjust your display settings to reduce the brightness and contrast of static images. You can also use a screen saver or a burn-in fixer app to periodically change the image on your screen.
Another way to prevent burn-in is to avoid displaying static images for extended periods. For example, you can set your TV to turn off after a few hours of inactivity or use a smartphone app that periodically changes the wallpaper. By taking these precautions, you can minimize the risk of burn-in and extend the lifespan of your AMOLED display.
Do all AMOLED displays suffer from burn-in?
Not all AMOLED displays are prone to burn-in. In fact, most modern AMOLED displays have features that minimize the risk of burn-in, such as pixel shifting, image retention compensation, and screen savers. These features can help reduce the visibility of burn-in and prevent it from becoming a permanent problem.
However, some AMOLED displays are more prone to burn-in than others. For example, older AMOLED displays or those with lower pixel densities may be more susceptible to burn-in. Additionally, devices that display static images for extended periods, such as TVs and video game consoles, may be more prone to burn-in than devices that display dynamic images, such as smartphones.
How long does it take for AMOLED burn-in to occur?
The time it takes for AMOLED burn-in to occur varies depending on several factors, including the display settings, the type of content being displayed, and the quality of the display. In general, burn-in can occur after displaying static images for several hundred hours.
However, the exact time it takes for burn-in to occur can vary significantly. For example, displaying a static image at maximum brightness and contrast can cause burn-in to occur in as little as 100 hours, while displaying a dynamic image at lower brightness and contrast may not cause burn-in even after 1,000 hours.
Is AMOLED burn-in covered under warranty?
Whether AMOLED burn-in is covered under warranty depends on the manufacturer’s policy. Some manufacturers, such as Samsung and LG, offer warranties that cover burn-in damage, while others may not.
If you suspect that your AMOLED display has burn-in, it’s essential to check your warranty terms to see if you’re covered. Even if burn-in is not explicitly mentioned in the warranty, you may still be able to get a replacement or repair if the damage is deemed to be a manufacturing defect.
