Can you introduce your company and technology?

Polar Light Technologies was founded with a clear ambition: to make microLED monolithic color display. Our proprietary technology is based on a pyramid-shaped GaN structure. This structure has several benefits that allows us to build a monolithic color display using microLEDs that can be less than 1 µm.

The MicroLED Industry Association (MIA) is pleased to announce its upcoming members-only webinar, dedicated to tiled large-area MicroLED displays.

In this session, MIA member company SiliconCore will take center stage to share insights into the market landscape, technology developments, and product innovations driving growth in this field. The webinar will delve into the unique challenges and opportunities of tiled MicroLED architectures, and the current market and industry status. 

The MicroLED Industry Association published its yearly plan, detailing its planned activities in 2026. The plan outlines key initiatives designed to foster innovation, strengthen industry connections, and provide valuable resources to its members. 

You can download the MicroLED Industry Association 2026 plan here. The plan in 2026 includes two in-person meetings, the first ever SID Displayweek MicroLED Association pavilion, topical webinars, a market and industry update meeting, a Fireside Chat meeting, white papers and roadmap publications - among additional discounts, speaking opportunities and other member benefits.

The MicroLED Industry Association is excited to announce that it will host, for the first time, a dedicated MicroLED Pavilion at SID Display Week 2026.

This special area will bring together several MicroLED Association members - leading companies and innovators from across the microLED ecosystem, highlighting the latest technologies and developments shaping the future of advanced displays. It will serve as a central hub for collaboration, networking, and knowledge exchange among microLED professionals.

We invite all attendees to explore the MicroLED Pavilion at Display Week 2026, meet members of the MicroLED Industry Association, and connect with the MicroLED‑Info team at our booth. We also invite our members to our annual SID Displayweek MIA dinner, sponsored by SmartKem in 2026.

For more than a decade, microLED technology has captured the imagination of display engineers, semiconductor innovators, and industry analysts. The promise has always been clear: unmatched brightness, durability, and energy efficiency. The challenge has been turning that promise into a mass-market reality, a process that has proven to be complex and slow.

Now, in 2025, the pieces are finally coming together. From materials breakthroughs to smarter manufacturing methods, microLED is at a critical inflection point. At Aledia, we have always believed that solving physics was only part of the equation. True success also depends on solving economics, process scalability, and systems integration.

This year, momentum is building across all these areas.

At the Core: Materials and Emission Mechanics

At Aledia, we are pioneering a fundamentally different approach to microLEDs. Unlike traditional planar technologies, our 3D microLED architecture, built from silicon nanowires, enables far greater light extraction, power efficiency, and manufacturability using existing 200 mm IC manufacturing lines.

The MicroLED Industry Association, in collaboration with Techblick, concluded a highly successful microLED industry event last week. MicroLED-Connect 2025, which took place in Eindhoven, The Netherlands, brought together over 300 industry professionals, supply chain companies, researchers, investors and early stage developers. 

During the event, which was co-located with ARVR-Connect 2025, over 40 speakers, including microLED professionals from Google, Mojo Vision, Aledia, ASML, JBD, Hongshi Intelligence, Trendforce, SCIL, Buhler Group, itec, QNA, Semilab, C-REAL, LAM Research, Smartkem, Trendforce and and others, discussed the latest innovations, roadmaps, challenges and applications of microLEDs, with a focus on the AR microdisplay segment. 

On November 25, 2025, the MicroLED Industry Association will host a MicroLED Industry Update Webinar, at 16:00 CET. All MicroLED Association members are invited to join.

In the webinar, we will share an update on recent microLED industry updates, and insights from 2025. There will also be an open discussion on the latest industry news and trends.

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!

ARVR-Connect 2025 is set to be an exciting event with a world-class agenda, exhibition and networking opportunities. Co-located with MicroLED-Connect 2025, it will focus on the image light path of AR devices - display engines (OLEDs, MicroLEDs, LCoS, lasers) and optics and waveguides. 

In this article we will introduce some of our speakers and themes at the event. You can explore the full agenda and event details here.

AR system design and headsets

The first theme we will discuss is the design of AR headsets, the system and mainly the integration of displays and optics. We will hear from several AR device makers and technologies suppliers, and here we mention a sample four of these talks.
