QustomDot and MICLEDI Collaborate for Polychromatic MicroLEDs Development Via Colour Conversion

Posted  by GoPhotonics


QustomDot, a color conversion developer for microLED displays, MICLEDI Microdisplays, a leading developer of microLED displays for Augmented Reality (AR) glasses, a spin-off of imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, announced a joint development program demonstrating a full-color microLED integration in polychromatic pixel arrays. The new technology addresses a growing demand for compact and energy-efficient microdisplays for AR applications.

The Flanders-based consortium enables technology for high-resolution and high-brightness microdisplays, combining:

  • Stable, RoHS-compliant Quantum Dot (QD) color conversion materials
  • New microLED architecture tailored for high-efficiency color conversion
  • High-throughput QD transfer and patterning techniques on micron-sized pixels

New QD materials for color 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. – says 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 color conversion. Our new pixel architecture has been optimized for high-aperture (>60% aperture at a 3µm pixel pitch) which is a key requisite to achieve high brightness with quantum dots” - says Dr. Soeren Steudel, MICLEDI CTO.

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” – says Prof. Geert Van Steenberge, R&D Team Leader at imec-UGent.
