ScreenWipe - Fix burn-in

About this app

High-end TVs and monitors often have built-in measures to protect against burn-in - so why shouldn't your phone?

What does it do?
ScreenWipe helps remove and mitigate screen burn-in, or pixel retention, by forcing the pixels into a fully on and fully off state.

How does it work?
Like with anything else, it helps to regularly move after staying in the same position for a long period. Pixels come in two main varieties that both benefit from regular change: LCDs and OLEDs.
LCDs, or liquid crystal displays, have millions of small liquid crystals suspended substrate that are controlled by an electrical field. These crystals refract light from a backlight based on their angle, and that refraction determines the color of the light outputted. These displays are less prone to burn-in, but they can still experience it under extreme circumstances. ScreenWipe can help reverse this by making sure all pixels cycle through the extreme ends of their color gamut.
OLEDs, or organic light emitting diodes, work entirely differently. Each pixel emits its own light, hence the name, which causes more heat and wear per pixel. The wear can be uneven if there are parts of the display that consistently show the same image. This can mean some areas of the screen are dimmer or less accurate colors. ScreenWipe can help make this less noticeable by more evenly wearing the pixels.

TL;DR: the pixels are pushed to reach their limits and get out of a sedentary state.
