Method of adapting emitted radiation from light-emitting diodes in pixels of a display apparatus, and display apparatus

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 comprise 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 the light-emitting diodes,
• all the pixels each comprise at least one light-emitting diode intermittently 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,
• for the measurement of the brightness an external light source from outside the display apparatus is used and the external light source is natural or artificial daylight, 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.
