Screen burn-in or ghosting is a discoloration of areas on an electronic display, such as a cathode ray tube display or an old computer monitor or television set, caused by non-uniform cumulative use of pixels.
It occurs most frequently on AMOLED and OLED screens, but it can also occur on IPS, TFT or PLS screens and have similar effects.
Burn-in Fix seeks to mitigate or eliminate the visual effects caused by ghosting and burn-in, forcing the entire screen to display the primary and secondary RGB colors in a static and random manner within a certain time interval.
