Abstract: A light-emitting semiconductor chip and a display device are disclosed. In an embodiment a light-emitting semiconductor chip includes an emission surface formed with a plurality of first emission regions and second emission regions, wherein the first emission regions and the second emission regions are configured to emit light of a predeterminable color location, wherein the first and second emission regions are separately controllable from each other, wherein the first emission regions and second emission regions are arranged next to one another in a first plane, wherein all second emission regions form at least a part of an outer edge of the emission surface, and wherein the first emission regions have a smaller extent than the second emission regions along at least one direction lying in the first plane.

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.
