A method of adapting emitted radiation from light-emitting diodes in pixels of a display apparatus, wherein the display apparatus has a multiplicity of pixels each arranged for adjustable emitted radiation of mixed light, the pixels each include at least two light-emitting diodes and, in operation, the light-emitting diodes emit in various colors so that the mixed light is composed of light of these light-emitting diodes, at least some of the pixels each include at least one light-emitting diode, which at least intermittently is operated as a photodetector and measures a brightness, by the measured brightness, an emittance of each of the affected light-emitting diodes or of the affected pixel is ascertained, and the light-emitting diodes are triggered in accordance with the ascertained emittance so that aging of the light-emitting diodes is at least partly compensated for.
