In this article, we’ll delve into the world of plasma screens, exploring the causes of burn-in, its effects, and whether it’s possible for it to go away.
What Is Plasma Screen Burn-In?
Burn-in, also known as image retention, is a permanent ghostly impression of an image that remains on a plasma screen even after the original image has changed. This occurs when a static image is displayed on the screen for an extended period, causing the phosphors to degrade and create a permanent mark. Burn-in can be caused by a variety of factors, including:
- Static images**: Video games, TV channels, and computer screensavers can all contribute to burn-in if they display static images for extended periods.
- High contrast**: Images with high contrast ratios can cause burn-in, as the phosphors are subjected to intense electrical currents.
- Low screen refresh rates**: Plasma screens with low refresh rates are more prone to burn-in, as the phosphors are not refreshed as frequently.
How Does Burn-In Affect Plasma Screens?
Burn-in can have a significant impact on the overall viewing experience of a plasma screen. The effects of burn-in can range from mild to severe and may include:
- Ghostly images**: A faint, ghostly impression of the original image remains on the screen, even after the image has changed.
- Color distortion**: Burn-in can cause color distortion, as the phosphors become degraded and lose their ability to produce accurate colors.
- Reduced contrast ratio**: Burn-in can reduce the contrast ratio of the screen, making it more difficult to distinguish between different shades of gray.
Can Plasma Screen Burn-In Go Away?
The good news is that, in some cases, plasma screen burn-in can be reversed or reduced. However, the success of this process depends on several factors, including:
- Severity of burn-in**: Mild cases of burn-in are more likely to be reversed than severe cases.
- Age of the screen**: Newer screens are more likely to recover from burn-in than older screens.
- Quality of the screen**: High-quality screens with advanced phosphor technology are more resistant to burn-in and more likely to recover.
Methods For Reducing Burn-In
There are several methods that can be used to reduce or reverse plasma screen burn-in:
- Image retention compensation**: Some plasma screens come with built-in image retention compensation features, which can help to reduce burn-in.
- Screen savers**: Using a screen saver can help to reduce burn-in by displaying a moving image or a blank screen.
- Pixel shifting**: Some plasma screens have a pixel shifting feature, which can help to reduce burn-in by slightly moving the image on the screen.
Pixel Shifting: A Closer Look

What Is Plasma Screen Burn-in And How Does It Occur?
Plasma screen burn-in, also known as image retention, is a phenomenon where a static image remains on the screen for an extended period, even after the image has changed. This occurs when a single image is displayed on the screen for a prolonged time, causing the phosphors in the plasma display panel to degrade unevenly. As a result, the affected areas of the screen may appear discolored or ghostly, with the image persisting even after the original image has been removed.
The risk of burn-in is higher when displaying static images, such as video game menus, TV channel logos, or computer desktops, for extended periods. Additionally, plasma screens are more susceptible to burn-in when they are new, as the phosphors are more prone to degradation. However, most modern plasma TVs have features to mitigate burn-in, such as pixel shifting and image retention compensation.
Can Plasma Screen Burn-in Be Completely Eliminated?
While it is not possible to completely eliminate the risk of plasma screen burn-in, there are steps that can be taken to minimize its occurrence. Many modern plasma TVs have built-in features to reduce the risk of burn-in, such as pixel shifting, which slightly moves the image on the screen to distribute the wear evenly. Additionally, adjusting the TV’s settings, such as reducing the brightness and contrast, can also help to reduce the risk of burn-in.
It is also important to follow proper usage guidelines to minimize the risk of burn-in. This includes avoiding the display of static images for extended periods, using a screen saver when the TV is not in use, and adjusting the TV’s settings to reduce the brightness and contrast. By taking these precautions, the risk of plasma screen burn-in can be significantly reduced.
How Can I Prevent Plasma Screen Burn-in On My TV?
