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 18):
An electronic display configured to perform a procedure for preventing the retention of an image displayed on the electronic display, comprising:\n an active display area; a display controller configured to produce an image on the active display area of the electronic display by transmitting image pixel data thereto; and a processor in electrical communication with the display controller, the processor programmed to:\n define an analysis area, \n move the analysis area through each of a plurality of locations across the active display area, each location corresponding approximately to a shape and size of the analysis area, \n perform a checksum calculation on the pixel data at each location for a predetermined time period, \n determine a change in value of the pixel data at each location during the predetermined time period, \n compare the determined change in value of pixel data for each location with a threshold value, and \n perform an image retention prevention procedure at any location where the change in value of the pixel data is determined to be less than the threshold difference value by causing image data and non-image data to be alternatingly transmitted to different portions of the pixels within the location.
