Screen burn-in, also known as image retention, is a common issue that affects various types of displays, including TVs, smartphones, and computer monitors. It occurs when a static image is displayed on the screen for an extended period, causing permanent damage to the display’s pixels. In this article, we will delve into the world of screen burn-in, exploring its causes, symptoms, and prevention methods.
What is Screen Burn-In?
Screen burn-in is a phenomenon where a static image is permanently etched into a display’s pixels, resulting in a ghostly impression that remains even after the image is changed or the display is turned off. This issue is more common in older display technologies, such as plasma and CRT (cathode ray tube) displays. However, with the advent of newer technologies like OLED (organic light-emitting diode) and QLED (quantum dot light-emitting diode), screen burn-in has become a concern for modern displays as well.
Causes of Screen Burn-In
Screen burn-in is caused by the prolonged display of static images on a screen. When an image is displayed for an extended period, the pixels that make up the image can become permanently damaged, leading to a ghostly impression. The following are some common causes of screen burn-in:
- Static images: Displaying static images, such as video game menus, TV channel logos, or computer desktop wallpapers, for extended periods can cause screen burn-in.
- Video games: Playing video games with static elements, such as menus, HUDs (heads-up displays), or mini-maps, can cause screen burn-in.
- TV broadcasts: Watching TV broadcasts with static logos, tickers, or other graphics can cause screen burn-in.
- Computer use: Displaying static images or graphics on a computer monitor for extended periods can cause screen burn-in.
How Screen Burn-In Occurs
Screen burn-in occurs when the pixels that make up a display are subjected to prolonged stress. When an image is displayed on a screen, the pixels that make up the image are excited, causing them to emit light. If the same image is displayed for an extended period, the pixels can become over-excited, leading to permanent damage. This damage can result in a ghostly impression of the image being permanently etched into the display.
Symptoms of Screen Burn-In
Screen burn-in can manifest in various ways, depending on the severity of the issue. The following are some common symptoms of screen burn-in:
- Ghostly impressions: A ghostly impression of a static image can remain on the screen even after the image is changed or the display is turned off.
- Image retention: A faint impression of a static image can remain on the screen for a short period after the image is changed.
- Discoloration: The affected area of the screen can become discolored, with a noticeable difference in brightness or color.
- Permanent damage: In severe cases, screen burn-in can cause permanent damage to the display’s pixels, resulting in a permanent ghostly impression.
Identifying Screen Burn-In
Identifying screen burn-in can be a challenging task, especially in its early stages. However, there are some methods to help you identify screen burn-in:
- Display a white screen: Displaying a white screen on your device can help you identify screen burn-in. If you notice any ghostly impressions or discoloration, it could be a sign of screen burn-in.
- Check for image retention: Displaying a static image on your device and then changing it can help you identify image retention. If you notice a faint impression of the previous image, it could be a sign of screen burn-in.
- Look for discoloration: Checking the affected area of the screen for discoloration can help you identify screen burn-in.
Prevention Methods
Preventing screen burn-in is easier than repairing it. The following are some prevention methods to help you avoid screen burn-in:
- Use a screen saver: Using a screen saver can help prevent screen burn-in by displaying a moving image or turning off the screen after a period of inactivity.
- Adjust the display settings: Adjusting the display settings, such as the brightness and contrast, can help prevent screen burn-in.
- Use a pixel shifting feature: Some modern displays come with a pixel shifting feature that can help prevent screen burn-in by slightly moving the image on the screen.
- Avoid static images: Avoiding static images, such as video game menus or TV channel logos, can help prevent screen burn-in.
Repairing Screen Burn-In
Repairing screen burn-in can be a challenging task, especially if the damage is severe. However, there are some methods to help you repair screen burn-in:
- Image retention compensation: Some modern displays come with an image retention compensation feature that can help repair screen burn-in by adjusting the display’s brightness and contrast.
- Pixel refresher: Some displays come with a pixel refresher feature that can help repair screen burn-in by refreshing the display’s pixels.
- Professional repair: In severe cases, professional repair may be necessary to repair screen burn-in.

Note: The vulnerability to screen burn-in can vary depending on the specific display model and usage patterns.
What is screen burn-in and how does it occur?
Screen 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 phenomenon occurs when the pixels on a screen are subjected to a static image, causing the organic compounds in the display to degrade and change color.
The degradation of pixels can be attributed to the way modern screens, especially OLED and plasma displays, work. When a static image is displayed, the pixels are constantly lit, leading to a buildup of heat and stress on the organic compounds. Over time, this stress causes the compounds to break down, resulting in a permanent ghostly impression on the screen.
What are the common symptoms of screen burn-in?
The most common symptom of screen burn-in is a ghostly impression of an image that remains on the screen even after the image has changed. This impression can be a faint outline of a logo, a menu bar, or any other static element that has been displayed for an extended period. In severe cases, the burn-in can be quite noticeable and may even affect the overall image quality.
Another symptom of screen burn-in is a decrease in image contrast and color accuracy. As the pixels degrade, they may not be able to produce the same level of brightness and color as before, resulting in a washed-out image. In some cases, the burn-in can also cause a yellowish or bluish tint to appear on the screen.
Which types of screens are most prone to burn-in?
OLED (Organic Light-Emitting Diode) screens are the most prone to burn-in due to the organic compounds used in their construction. These compounds are susceptible to degradation when subjected to static images, making OLED screens more vulnerable to burn-in. Plasma screens are also prone to burn-in, although to a lesser extent.
LCD (Liquid Crystal Display) screens, on the other hand, are less prone to burn-in. This is because LCDs use a different technology that is less susceptible to degradation from static images. However, it’s worth noting that some LCDs, especially those with LED backlighting, can still be prone to burn-in under certain conditions.
How can I prevent screen burn-in on my device?
One of the most effective ways to prevent screen burn-in is to use a screensaver or turn off the screen when not in use. This helps to reduce the amount of time that static images are displayed, minimizing the risk of burn-in. You can also adjust the screen’s brightness and contrast settings to reduce the stress on the pixels.
Another way to prevent burn-in is to use a feature called “pixel shifting” or “image retention compensation.” This feature, available on some devices, subtly moves the image on the screen to prevent static pixels from degrading. You can also try to avoid displaying static images for extended periods, such as turning off the TV when not watching it.
Can screen burn-in be fixed or reversed?
In some cases, screen burn-in can be reversed or fixed, but it depends on the severity of the burn-in. If the burn-in is mild, it may be possible to reverse it by displaying a series of images that are designed to “reset” the pixels. This can be done using a specialized software or by displaying a screensaver that is designed to counteract burn-in.
However, if the burn-in is severe, it may be permanent and cannot be reversed. In such cases, the only option may be to replace the screen or the device altogether. It’s worth noting that some manufacturers offer warranties that cover burn-in, so it’s worth checking your device’s warranty terms and conditions.
How long does it take for screen burn-in to occur?
The time it takes for screen burn-in to occur can vary depending on several factors, including the type of screen, the brightness and contrast settings, and the amount of time that static images are displayed. In general, burn-in can occur in as little as a few hours or as long as several months.
For example, if you display a static image on an OLED screen at maximum brightness for several hours a day, you may start to notice burn-in within a few weeks. On the other hand, if you display a static image on an LCD screen at low brightness for short periods, it may take several months or even years for burn-in to occur.
Are there any devices that are completely immune to screen burn-in?
While there are no devices that are completely immune to screen burn-in, some devices are more resistant to it than others. For example, some LCD screens with IPS (In-Plane Switching) technology are designed to be more resistant to burn-in than OLED screens.
Additionally, some devices, such as e-readers, are designed to display static images for extended periods and are therefore less prone to burn-in. These devices typically use e-ink technology, which is designed to be more resistant to burn-in than traditional LCD or OLED screens.
