Manufacturing Processes & Integration
Advances in Mass Transfer Processes for MicroLED Chip Integration
Mass transfer remains one of the biggest hurdles for cost-effective microLED displays. At MicroLED-Connect 2024, Toray Engineering presented a new transfer method combining microLED chips with a panel-level package.
Stamp-Based Imprinting for AR Waveguide Manufacturing
Waveguides are key for AR devices, but must balance cost and performance. At Display Innovation Day (Dec 2024), SCIL presented its stamp-based system for waveguide imprinting as a scalable solution.
Wafer-to-Wafer Integration for MicroLED Microdisplays
Wafer-to-wafer processes are emerging as the path to mass production of microLED microdisplays. At MicroLED-Connect 2024, MICLEDI (imec spin-out) detailed its 300 mm CMOS integration flow and why wafer-level integration is critical.
Integrated Production Platforms for Scalable MicroLED Manufacturing
At MicroLED-Connect 2024, VueReal presented its platform for scalable microLED display production, addressing key challenges in cost, yield, and throughput.
Materials Innovations
Challenges and Advances in Native Red MicroLED Efficiency
Native red microLEDs remain a bottleneck for performance. At MicroLED-Connect 2024, UCSB’s Prof. DenBaars presented the latest advances in tunnel-junction technology and efficiency gains versus OLED benchmarks.
Etching and Deposition Solutions for MicroLED Materials
Oxford Instruments shared processing solutions for GaN and InGaAlP materials, including AlInGaP etching and ALD-based passivation.
Perovskite Quantum Dots for High-Density Color Conversion
CEA-Leti’s Prof. François Templier presented research on perovskite quantum dots achieving sub-micron densities for color conversion in microLED displays.
Progress Toward Emissive Quantum Dot–EL Displays
QNA Technology updated on progress towards QD-EL displays, sharing the latest status of emissive quantum dot research and scalability.
Cubic GaN as a Novel Platform for Scalable MicroLEDs
Kubos Semiconductors detailed its cubic GaN material system, showing how it can enable efficient, scalable microLED manufacturing.
Metrology, Testing & Inspection
MicroLED Wafer Metrology and Calibration Strategies
MicroLED displays remain at an early stage, making precise optical measurement and wafer inspection critical for success. In our Display Innovation Webinar (Dec 2024), Tobias Steinel (Instrument Systems) introduced PL and EL test strategies, and highlighted how calibration reduces errors and improves performance in mass production.
