Scrona and Avantama Collaborate to Redefine Quantum Dot Processing with EHD High Patterning Resolution for Displays
ZURICH, Jan. 23, 2024 /PRNewswire/ -- Scrona AG, the additive manufacturing startup and world record holder of the smallest ever printed color picture, and Avantama, a leader in high-tech materials for electronics, today announced that they have successfully processed high-performance quantum dot (QD) ink using Scrona's electrohydrodynamic (EHD) inkjet printing. This collaboration combines the benefits of the inkjet process with high-patterning resolution to drive a new generation of efficient and cost effective MicroLED displays, while also increasing color purity and brightness, and improving overall pixel production tact time.
- "We continue to find new applications of EHD that will meet the demands of the industry by offering an additive, completely waste-free process with higher resolution capabilities than lithography patterning," said Dr. Patrick Galliker, co-founder and CEO of Scrona.
- "Conventional inkjet printing is not a viable option for emerging MicroLED displays because they use much smaller pixels than QD-OLED displays," said Dr. Norman Lüchinger, co-founder and CTO at Avantama.
- Scrona print head technology processes QD inks using EHD inkjet printing, whereby droplets are ejected from a nozzle by electrostatic forces.
- Perovskite QDs have the highest weight-based absorption compared to others QDs, and this directly translates to very high OD/thickness values.
