Abstract: A method for operating a display device is disclosed. In an embodiment, a method for displaying images or films via a display device includes emitting, for each radiation direction, a partial image composed of sub-pixels of all pixels belonging to this radiation direction and receiving control data for at least some of the sub-pixels at the display device by a data compression algorithm, wherein the data compression algorithm comprises a delta coding, wherein the delta coding includes an initial value, wherein the initial value includes one of the partial images defined as a main image, wherein at least some of the remaining partial images are received as deviations from the main image, and wherein edges of a three-dimensional object to be displayed are excluded from data compression when merging surfaces enclose a real angle of 135° or less.
