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.

Abstract: The invention relates to a method for classifying a light-emitting semiconductor component (301) for an image sensor application, wherein the semiconductor component (301) is designed as a light source for an image sensor (302), comprising the following steps: providing the light-emitting semiconductor component (301); determining at least one of the following parameters of the light emitted with an emission spectrum by the light-emitting semiconductor component (301) during operation: R=∫qR(λ)·S(λ)dλ·texp, G=∫qG(λ)·S(λ)dλ·texp, B=∫qB(λ)·S(λ)dλ·texp, wherein qR(λ), qG(λ), and qB(λ) are spectral sensitivities of a red, green, and blue color channel of the image sensor (302), S(λ) is the emission spectrum of the light-emitting semiconductor component (301), texp is an exposure time, and λ designates a wavelength; classifying the light-emitting semiconductor component (301) into a class from a group of classes, which are characterized by different value ranges of at least one parameter that depends on at least one of the parameters R, G, and B. The invention further relates to an image sensor application.
