Screen burn-in, also known as image retention or ghosting, is a phenomenon that can occur on Organic Light-Emitting Diode (OLED) and Plasma displays. It’s a permanent defect that causes a faint impression of an image to remain on the screen for an extended period, even after the image has been removed. In this article, we’ll delve into the world of screen burn-in, exploring how to test for it, prevent it, and what to do if you’re already experiencing it.
What Causes Screen Burn-In?
Before we dive into testing and prevention strategies, it’s essential to understand what causes screen burn-in in the first place. There are several factors that can contribute to this issue:
Static Images
One of the primary causes of screen burn-in is static images. When an image remains on the screen for an extended period, the pixels can become damaged, leading to a permanent impression. This is especially true for images with bright colors, high contrast, or high pixel density.
Inadequate Screen Timeout
If your screen timeout is set too high, it can increase the risk of screen burn-in. When the screen remains on for an extended period, the pixels continue to degrade, making them more susceptible to burn-in.
Bright Screens
Bright screens can also contribute to screen burn-in. When the screen is set to maximum brightness, the pixels are worked harder, increasing the risk of damage.
Inadequate Screen Protection
Not using a screen protector or turning off features like screen savers can increase the risk of screen burn-in. Screen protectors help to absorb impact and reduce the risk of scratches, which can contribute to burn-in.
How to Test for Screen Burn-In
Now that we’ve covered the causes of screen burn-in, let’s explore how to test for it.
The Black Screen Test
One of the simplest ways to test for screen burn-in is to display a black screen. To do this:

How does screen burn-in occur?
Screen burn-in, also known as image retention or ghosting, is a phenomenon that occurs when a static image is displayed on a screen for an extended period. This can happen on various types of displays, including OLED, plasma, and LCD TVs, as well as mobile devices and computer monitors. When the same image is displayed for a long time, the pixels responsible for rendering that image can become “burned in” or permanently damaged, leaving a faint impression of the image even when the display is turned off or a different image is shown.
The likelihood of screen burn-in increases when the display is showing the same image for an extended period, such as video game menus, TV channel logos, or scoreboard displays. Furthermore, displays with poor pixel rotation or refresh rates are more susceptible to burn-in. It’s essential to take preventative measures to minimize the risk of screen burn-in and ensure the longevity of your display.
What are the common signs of screen burn-in?
One of the most common signs of screen burn-in is a faint, permanent impression of an image or text on the display. This can appear as a ghostly outline or a faded version of the original image. In some cases, the burn-in can be more pronounced, resulting in a noticeable discoloration or distortion of the affected area. Another indication of screen burn-in is when the display has difficulty rendering certain colors or shades, leading to an uneven or washed-out appearance.
If you suspect that your display is experiencing screen burn-in, try adjusting the brightness or contrast settings to see if the issue persists. You can also try displaying a full-screen image of a different color to see if the burn-in is masked. If the problem persists, it may be a sign of more severe screen damage that requires professional attention.
Can screen burn-in be prevented?
Yes, screen burn-in can be prevented or minimized with the right precautions. One of the most effective methods is to set your display to turn off or switch to a screensaver after a certain period of inactivity.
