  • Patent number: 10490761
    Abstract: A light-emitting component provides an emitter layer including phosphorescent and fluorescent emitter materials, and at least one predefined first and second display regions. The first region has both emitter materials. The second region has the phosphorescent emitter material. A first electromagnetic radiation is emitted upon the transition from the first excited state to the ground state of the phosphorescent emitter material. A second electromagnetic radiation is emitted upon the transition from the excited state to the ground state of the fluorescent emitter material. The excited state of the fluorescent emitter material is occupied by an energy transfer from the second excited state of the phosphorescent emitter material to the excited state of the fluorescent emitter material so that a mixed light composed of first and second electromagnetic radiations is emittable from the first region, and the light that is emittable from the second region is free of second electromagnetic radiation.
