Abstract:
A method for preventing image retention in an electronic display, and an electronic display configured to perform such a method. A time period and a pixel threshold may be defined. A checksum calculation of all pixel data within an active image area of the electronic display is preferably performed during the predetermined period of time. A checksum calculation is then performed to determine if the change in pixel data during the period of time is less than the pixel threshold. If not, an image retention prevention procedure is conducted for each area of the active image area of the display where the threshold value was not met. Generally, the image retention prevention procedure includes transmitting alternate pixel data to at least a portion of the pixels within the subject area.

Claim (Index 11):
A method for preventing the retention of an image displayed on an active area of an electronic display, the method performed by the electronic display and comprising the steps of:\n defining an analysis area of some shape and of a size that is some fraction of the active area of the electronic display; virtually dividing the active display area of the electronic display into a plurality of locations, each location corresponding approximately to the shape and size of the analysis area; moving the analysis area through each location and performing a checksum calculation of pixel data associated with each location for a predetermined time period; comparing the pixel data checksum values as calculated for each location during the predetermined time period to determine a change in said pixel data checksum values; comparing the change in said pixel data checksum values for each location with a threshold difference value; and performing an image retention prevention procedure at any location where the change in pixel data checksum values is determined to be less than the threshold difference value by alternatingly transmitting image data and non-image data to different portions of the pixels.
