This application will cycle your screen through black, gray, and white screens at 2 second intervals.

The purpose of this application is to exercise the LCD pixels to get rid of any image persistence problems. Image persistence may occur if the same image is displayed on an LCD screen for a prolonged period of time. The image forms a kind of after-effect on the screen. In some cases, this can be removed by alternating the on/off state of the pixels. Screen Clean does this for you.
