  • Optoelectronic component and manufacturing method
    Patent number: 6586268
    Abstract: An optoelectronic component and a method of manufacturing such a component. The component includes at least one pixel comprising a first and a second electrode for electric coupling. An optoelectronically active material is between the electrodes. The optoelectronically active material is a hybrid sol-gel glass that is chemically supplemented with a material affecting the optoelectronic properties. The component is manufactured by spreading the optoelectronically active hybrid sol-gel on the first electrode, hardening the hybrid sol-gel glass by radiation, and forming the second electrode on the optoelectronically active hybrid sol-gel glass.
