Quantum Dots

As part of its continued scale-up and industrialisation efforts, Belgian quantum dot company QustomDot has appointed Arne Dekeyser as Chief Operating Officer.

Arne brings more than 10 years of experience in industrial operations, gained through roles at Barco and later at Sumitomo Bakelite. With a strong background in operational scaling, manufacturing processes and development programs in automotive-related environments, his profile aligns closely with QustomDot's roadmap as the company further expands its production capabilities and strengthens its position in high-performance MicroLED applications.

Raysolve Optoelectronics has demonstrated its latest microLED microdisplays at Displayweek 2026, both monochrome and color versions. The company also demonstrated a range of AR waveguide solutions developed with partners. 

The PowerMatch 1 monochrome green microLED display achieves a brightness of 7 million nits (10 lumens of luminous flux). The company says that this high brightness is an improvement over previous versions in both device brightness and optical efficiency, achieved by its continuous refinement of manufacturing processes and optical architecture.

Saphlux has successfully completed its Series C funding round, raising 300 million Yuan (around $43.5 million USD)., from several Chinese investment funds and VCs. 

Saphlux says that it will utilize the funds to accelerate its R&D and achieve mass production of full-color AR microdisplays.

Researchers at the CEA-Leti institute (a MicroLED Association member institute) developed green and red-emitting thin-film perovskite color conversion layers (CCLs) using pulsed laser deposition (PLD), that can be used in microLED microdisplays.

The researchers say that while QDs provide a good solution for color conversion microLED displays, they suffer from low absorption, which means that require a thickness of 3-10 micron, which is a challenge for very small microLEDs, required for microdisplays.

Belgium-based QD developer and MicroLED Association member QustomDot announced that it is expanding its activities in China as microLED programs advance toward pilot production and volume manufacturing.

The expansion in China includes appointing a local staff member to support technical evaluation, integration activities, and commercial coordination with regional panel makers and equipment partners.

Quantum dots developer and MicroLED Association member QustomDot, a spin-off from Ghent University, announced the commercial availability of its second-generation QustomJet Red ink.

QustomDot says that this new cadmium-free, solvent-free inkjet ink is specifically designed for quantum dot color conversion (QDCC) applications in microLED displays. The new ink delivers multiple competitive advantages for display manufacturers: excellent optical specs, enhanced printability with standard industrial inkjet systems, superior shelf life stability, and exceptional reliability under high-intensity blue light exposure, addressing the key challenges that have limited widespread adoption of quantum dot color conversion.

MicroLED developer Saphlux announced that is has signed a strategic collaboration agreement with AR developer Vuzix, to co-develop high performance optical solutions for next-gen microLED-powered AI/AR glasses.

In this partnership, Saphlux will supply its T1 (first-gen) 0.13" monochrome microdisplay for Vuzix to incorporate it with its proprietary waveguides and system design expertise. Looking forward, the two companies plan to expand their collaboration to develop a full-color AR optical solution.

Researchers from Korea's Daegu Gyeongbuk Institute of Science and Technology (DGIST) developed a stretchable QD color conversion layer, that offers high performance even when stretched by over 50%.

The researchers applied this new QD-CCL film to a microLED device, thus enabling a high resolution (313 PPI) full color stretchable microLED display.

The MicroLED Industry Association published a new white paper that provides a discussion on microLED full color architectures. The white paper is openly available to download here.

One of the key challenges still facing the microLED industry is the development of full color displays. As blue, green and red LEDs are based on different material structures, producing full-color displays is not straightforward. MicroLED display developers are looking at several full color architectures, including a native GaN red microLED, color-tunable LEDs, color conversion using phosphors/QDs, and alternative material platforms (such as 3D Nanowires) and processes.

The MicroLED Association Full Color Architectures white paper addresses the challenges associated with producing full color microLED displays, and details the different architectures and technologies being developed today. You can download the full white paper here!

MicroLED-Connect 2025 is set to be the industry’s premier event for 2025, with a world-class agenda, exhibition and networking opportunities. In this article we will introduce some of our speakers and themes in the event. You can explore the full agenda and event details here.

Mass transfer – lasers, fluids and chip-first processing

The first theme we will discuss is mass transfer. In most MicroLED production platforms, there is at least one transfer process – from epiwafer to final display, and usually at least two such processes are involved: from epiwafer to an interposer substrate (temporary holder)  and then from interposer to final display. Performing this transfer in a cost-efficient and reliable manner is still one of the major challenges the industry is facing.
