Liquid crystal displays are susceptible to image persistence—what we used to call “burn-in” on old CRT monitors. Leaving any image (including your system’s desktop icons, windows, and menus) on-screen for too long can cause unsightly ghost images to set in.
Unlike CRTs, however, LCDs with image persistence can be repaired with special video patterns. This saves the cost of buying a new display, or (in the case of a laptop) an expensive repair.
That’s why toastycode brings you…
LCD Scrub.
Why?
Because we want to make it easier for regular Mac users to fix
their burned-in displays without hours of Internet research and a lot of setup hassle.

about the experience that led to the creation of LCD Scrub.
Features.
-
Erases persistent images.
- LCD Scrub uses recommended techniques from
Apple,
NEC, and other manufacturers (plus some of our own tricks) to gradually “scrub” away residual images from liquid crystal displays.
-
Includes several different video sequences.
- Certain patterns seem to work better on some displays than others. If, after a few hours of use, one pattern seems to be ineffective, try another.
-
Runs as a screen saver module.
That means there’s no app to remember to run; LCD Scrub will do its job when you’re not around, and gets out of your way quickly when you need to work.
-
Try before you buy.
Until you register, LCD Scrub will only work for a few minutes and will only use some of its video patterns. You'll be able to see how it works, and to use it to repair very slight damage, in this mode. But to reverse significant image persistence, you'll need to purchase a license (see links at right).
Instructions.
- Download the LCD Scrub zip archive. Double-click to extract LCD Scrub.saver; double-click again to install.
- Choose one of LCD Scrub’s available repair patterns.
- Wait. Scrubbing typically takes an hour or two to start showing results, and 6–12 hours or more to entirely remove a residual image.
