Fraunhofer FEP Showcases High-Speed Light Modulation for OLED, Micro-LED and LCOS arrays

High-resolution light modulators play a crucial role in shaping the graphical experience in virtual reality (VR) glasses or the performance in optical communication. Fraunhofer FEP has developed a new backplane architecture for light modulation, enabling extremely high refresh rates that lead to improved image quality and optical modulation.

Fraunhofer FEP: Condition monitoring of ornamental plants with microdisplays and neural networks to optimise fertilisation

Conservation of resources and reliable yields are just as essential in plant cultivation as in other branches of agriculture. In order to optimise fertilisation processes in ornamental plant cultivation in the future and thus protect the environment, researchers at the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP (Dresden, Germany) together with the Saxon State Office for Environment, Agriculture and Geology (LfULG) have been researching a technology for the early detection of nutrient deficiencies or surpluses in ornamental plants in the ZierSens project (financed by funds from the Free State of Saxony). The use of bidirectional OLED microdisplays in combination with neural networks should make it possible to optimize fertilisation processes in the future.

Fraunhofer FEP: Integrable system traverse for innovative 2D inline process monitoring

The coating of flexible substrates such as ultra-thin glass or web with functional layers is highly efficient thanks to the use of roll-to-roll (R2R) technologies. Crucial for plant operators and ultimately for the price is the coating thickness homogeneity and thus also the electrical properties of the applied coatings for a high and above all constant yield without rejects. Until now, the electrical properties of the coating could only be determined and analysed at defined measuring points. Within the joint project KODOS – Fabricated Thin Glass Composite for Optoelectronic Systems (funding reference 13N14607), funded by the German Federal Ministry of Education and Research, an integrable solution for in-line process monitoring and mapping of process parameters was developed with the project partner SURAGUS GmbH at Fraunhofer FEP in Dresden, Germany.
