Abstract
A display includes a plurality of pixels. The pixels include at least one emitter unit. The emitter units each include a primary emitter and a secondary emitter for generating light of the same color. The secondary emitter is associated with the primary emitter of the corresponding emitter unit. The primary emitters and the secondary emitters are based on at least one semiconductor material. The emitter units each include a correction circuit. The correction circuits are each configured to be able to switch the generation of light from the primary emitter to the associated secondary emitter in case of a defect of the associated primary emitter.
