Abstract
A method for operating a display comprising providing a first feed of a first sequence of image data and providing a second feed of a second sequence of image data, the second feed comprising a second sequence of image data and a second complementary sequence of image data. The display is operated at a high display frame rate (HDFR) comprising HDFR image slots/slices during a standard frame rate (SFR) time interval. The method includes displaying the first feed and the second feed in a time-sliced multiplexed manner in the HDFR image slots of each SFR time interval. The first feed and the second feed comprise gray images obtained from the combination of image data presented at equal luminance and being evenly distributed within the HDFR image slots so the luminance changes of the display occur at frequencies greater than or equal to twice the SFR.
