Patent ID: 7317430

Claim:
A visual display comprising: a display installation including: a display panel including a plurality of pixels each having a bit depth; and an interface in communication with the display panel for receiving a video input and for driving the display panel during an active burn mode; and a computer in communication with the display installation for: determining a primary burn value for each of the pixels for the active burn mode; identifying a pixel having a low primary burn value indicating that the identified pixel has been burned at a greater degree than a number of other pixels; and determining a number of pixels each having a primary burn value higher than the low primary burn value indicating that the number of pixels have been burned at a lesser degree than the identified pixel; wherein the computer causes the interface to drive the display panel during a reverse burn mode such that the number of pixels having a primary burn value higher than the low primary burn value are burned to reduce the respective differences between higher primary burn values and the low primary burn value.
