Overview
"Screen Burn-in Repair" is an application for repairing the burn-in phenomenon that can occur on screens of devices such as smartphones, tablets and TVs. With this app, burn-in caused by displaying the same image for a long time can be effectively reduced or removed.
Screen burn-in happens when fixed elements remain on a screen for prolonged periods. Examples include home screen icons, the status bar, or persistent UI elements in games that may leave ghost images over time.
This app can detect screen burn-in and repair it automatically. The repair method works by displaying an appropriate pattern on the screen to eliminate the ghosting. The time required is short in many cases — often just a few minutes — making it easy to use.
The app offers an intuitive, easy-to-use interface and is designed to run comfortably even on lower-spec devices, making it suitable for a wide range of users.
How to Repair Screen Burn-in
1. Enable a screensaver
Enable a screensaver so the same static image is not shown for long periods. Use screensavers that move gradually across the screen or that display random patterns covering the entire screen.
2. Adjust the brightness
Lowering the screen brightness can help reduce burn-in. Set the brightness to a moderate level — excessively high brightness accelerates burn-in.
3. Give the screen a break
When using a screen for extended periods, give it regular breaks. Turning off the screen or switching the displayed content periodically helps prevent burn-in.
4. Use screen repair apps
If burn-in has already occurred, repair apps can help. They work by displaying specific patterns or colours to reduce the visible ghosting.
This app implements option 4. It fixes screen burn-in by continuously displaying a white screen. Leave the app running with the white screen displayed for several hours.

Use cases for repairing burn-in with a white screen
1) Smartphone screens
A smartphone screen can develop burn-in if the same image is shown for a long time. Displaying a white screen can help eliminate the burn-in.
2) Television screens
A television may develop burn-in from prolonged display of static images. A white screen can help reduce or remove the burn-in.
3) Computer monitors
Computer monitors exposed to static images for long periods can also suffer burn-in. Displaying a white screen may help eliminate it.
4) Digital signage in stores
Digital signage that shows the same content for long periods can develop burn-in. Running a white screen can help remove the ghosting.
These are examples where a white screen can be used to repair screen burn-in. To prevent burn-in, regular maintenance and varied content display are important.
