Electron Beam Patterning for Full-Color HR OLED Displays
OLED microdisplays are increasingly establishing themselves in consumer-ready wearables and data glasses. In order to meet the requirements for higher efficiency, higher contrast, and higher resolutions in these applications, Fraunhofer FEP scientists have developed a new micropatterning approach for OLEDs on silicon substrates. This might eliminate the use of color filters and shadow masks in the future and allow full-color displays to be developed by means of a new process. An increase in efficiency and considerably broader color gamut have already been demonstrated in first experiments.

Kyocera Offers World's First Full-Spectrum LED Aquarium Lighting for Japan
Kyocera Corporation (President: Hideo Tanimoto) announced that the company developed the world's first [1] full-spectrum LED lighting for aquariums. Kyocera's high-color-rendering LED lighting combines its proprietary violet LEDs and RGB (red, green and blue) phosphors to create lights close to natural sunlight at specific underwater depths. Kyocera's new LED lighting is ideal for growing various water creatures as it reproduces the light close to the natural habitats of corals and water plants. The optical spectrum can also be customized to reproduce the deep blue color for ornamental purposes.

KAIST Team Develops Flexible Blue Vertical Micro LEDs
In CES 2018, micro LED TV was spotlighted as a strong candidate for replacing the active-matrix organic light-emitting diode (AMOLED) display. Micro LED is a sub-100 um light source for red, green and blue light, which has advantages of outstanding optical output, ultra-low power consumption, fast response speed, and excellent flexibility. Professor Keon Jae Lee from the Department of Materials Science and Engineering and his team have developed a low cost production technology for thin-film blue flexible vertical micro LEDs (f-VLEDs).
