# OLED Burn-in: The Causes and How to Fix it?

OLED burn-in is a phenomenon where a static image can become permanently "burned" into an OLED display, causing a ghost image to appear even when other content is being displayed.

It can be checked using the [OLED burn-in test](https://darkblackscreen.com/oled-burn-in-test) which can detect the intesity and location of screen burn in on your display.

OLED burn-in occurs when a static image is displayed on the screen for an extended period, causing certain pixels to age faster than others. Over time, these pixels become permanently brighter or darker than the surrounding pixels, resulting in a ghost image that is visible even when the screen is showing different content.

## Causes of OLED Burn-in

There are several factors that can contribute to OLED burn-in, including:

- **High brightness:** OLED burn-in is more likely to occur when the screen is set to high brightness levels for extended periods.

- **Static content:** Any static content that is displayed on the screen for long periods can contribute to burn-in. This includes things like logos, channel icons, and game HUDs.

- **High contrast content:** Content that has high contrast, such as white text on a black background, can also contribute to burn-in as the brighter pixels will age faster than the darker ones.

## Preventing Screen Burn in

While OLED burn-in can be a frustrating problem, there are several steps that can be taken to prevent it from occurring:

1. **Reduce screen brightness:** One of the simplest ways to reduce the risk of burn-in is to reduce the screen brightness. This can be done by adjusting the brightness settings on the device or by using a dark mode or night mode.

2. **Use screen savers:** Screen savers can help prevent burn-in by automatically displaying moving images or patterns when the screen is idle. This can help prevent static images from being displayed for extended periods.

3. **Avoid static content:** To reduce the risk of burn-in, it's best to avoid displaying static content on the screen for extended periods. This can include things like leaving a game paused for a long time or keeping a news channel on the screen for hours.

## Ways to fix OLED Burn-in
If OLED burn-in does occur, there are a few potential solutions:

- **Run a pixel refresh cycle:** Most modern OLED displays have a built-in pixel refresh cycle that can help reduce burn-in. This involves displaying a series of patterns and colors to help "reset" the pixels and reduce the appearance of burn-in.

- **Display a [white screen](https://whitescreentest.com):** In some cases, displaying a white screen for an extended period can help reduce the appearance of burn-in. This works by helping to "age" the brighter pixels and reduce the contrast between them and the surrounding pixels.

In conclusion, OLED burn-in can be a frustrating problem for those who own OLED displays. By taking steps to reduce screen brightness, avoid static content, and use screen savers, users can reduce the risk of burn-in occurring. If burn-in does occur, running a pixel refresh cycle or displaying a white screen can help reduce its appearance.
