This new technology looks to address the growing demand for compact and energy-efficient microdisplays for AR applications. MICLEDI is a spin-off of IMEC, the research and innovation hub in nanoelectronics and digital technologies.
This project is being supported by the Flanders Innovation and Entrepreneurship (VLAIO), a consortium that is focused on the development of technology for microdisplays with high-resolution and high-brightness, combining:
- Stable, RoHS-compliant Quantum Dot (QD) colour conversion materials
- New microLED architecture tailored for high-efficiency colour conversion
- High-throughput QD transfer and patterning techniques on micron-sized pixels
“New QD materials for colour conversion are a game changer. Our patented method for producing RoHS-compliant QDs deliver high-quality and stable materials. This makes them effective for microLED applications, which will accelerate product development in this untapped market,” said Willem Walravens, CTO QustomDot.
“Polychromatic arrays are an important development for microLED products. The manufacturing precision of MICLEDI’s 300mm microLED approach is a perfect enabler for highly efficient colour conversion. Our new pixel architecture has been optimised for high aperture (>60% aperture at a 3 µm pixel pitch) which is a key requisite to achieve a high brightness with quantum dots,” explained Dr. Soeren Steudel, CTO at MICLEDI.
“We are pleased to support the new microLED developments with IMEC’s extensive technology background and know-how in the field of high-resolution patterning and transfer. We will continue moving the state-of-the-art in pixel resolution, uniformity, and process throughput,” said Professor Geert Van Steenberge, R&D Team Leader at IMEC-UGent.
