France-based Hummink develops high percussion capillary printing technology, that enables a highly controlled and prices (sub-micron scale) deposition of materials. The company's VP Business Development, Dr. Frederic Raynal, will give a lecture at the upcoming MicroLED-Connect virtual webinar on November 2023, and was kind enough to answer a few questions we had.
Hello Dr. Raynal. Can you give us a short intro to your company and microLED product/service?
Hummink is the leading developer and supplier of High Precision Capillary Printing (HPCAP), a revolutionary technology in many applications including the display and semiconductor industry. Spun-off from world-renowned research institutes, the company is based in Paris, with representatives in key regions (Korea, US, Taiwan, Japan, Europe). HPCAP involves the controlled deposition of materials, achieving high pixel densities with accurate alignment at extremely small sizes (sub-micronic scale), which is mandatory for the manufacturing of current and future generations of MicroLED. Hummink is a technology provider, enabling customers to have access to both equipments and inks through a single partnership.
What will you talk about during the microLED Connect's event?
Our talk will be on the printing resolution, precision and accuracy required to manufacture MicroLEDs. Reducing the size of pixels is a key goal in MicroLED display technology development. Smaller pixel sizes allow for higher resolutions, improved image quality, and more compact displays.
As pixel becomes smaller, precise placement and alignment becomes crucial to maintain the integrity of the display. Achieving an accuracy better than 5 micrometers is a challenging endeavor due to several technical and practical limitations inherent in the processes and technologies involved.
What do you think are the main challenges in the MicroLED Industry today?
Manufacturing cost is the main challenge of the MicroLED industry today.
What market segments do you feel will be the first to adopt MicroLEDs?
Microdisplays to be used in AR and VR
Which next-gen technologies do you think are most promising for the future of the microLED display industry?
MicroLED pixel sizes lower than 10 micron, for which OLED competition will have a lot of challenges.
Thank you Dr. Raynal, looking forward to hearing your lecture in November!
