Perovskites are a family of materials with the same basic structure that can have an impressive array of interesting properties, including unique optical properties. Metal halide perovskites offer several advantages for use as components of LEDs and displays. They are direct-bandgap semiconductor materials that possess high photoluminescence quantum yield (PL QY) reaching 100%, they have narrow and symmetric PL peaks (full width at half-maximum about 15–30 nm, which is even better than for the traditional QDs) that enables wide color gamuts and they can easily be synthesized and processed at room temperature, or vapor-processed at low temperatures (typically <180°C) using inexpensive precursors.

Perovskite materials can benefit the MicroLED industry in two ways: as materials for color conversion (using perovskite-based QDs) and in perovskite-based LED emitters. Much R&D work is taking place on both these fronts, and interest seems to be growing.

MicroLED Connect is a global forum for microLED and related technologies and applications, which will take place at the Convention Center on the High Tech Campus in Eindhoven on 25-26 September. The MicroLED Connect is organized by two industry veterans, Metalgrass’ Ron Mertens and TechBlick’s Khasha Ghaffarzadeh, each bringing his unique knowledge and experience to plan this extraordinary event.

We had a few questions to ask Khasha Ghaffarzadeh, our co-organizer, about his vision for this conference.

Q. Hi Kasha! We'd love to hear your thoughts on the MicroLED Connect event - what did you have in mind when planning it and what’s special about it? 

Hi! Well, it is the first worldwide onsite conference and exhibition dedicated to MicroLED technology. Up until now, MicroLEDs were highlighted in other display events, but never as the main technology in a dedicated conference. We felt that this emerging technology deserves to be the main focus. The event will bring together the entire value chain from around the world- from material suppliers to equipment makers to display makers and semiconductor companies and final OEMs. There is enormous interest in this technology and in our event, and so we expect a sell-out crowd.  

When planning this event, we put extra emphasis on social events and networking opportunities. We have a rich agenda that transcends the usual talks and lectures, and includes social gatherings, organized visits to companies in the area and more. We wish to give attendees the chance to not only listen and learn, but also interact and connect. We put a strong focus on in-person experience, hoping to forge deep partnerships amongst our participants. That’s actually where the name “MicroLED Connect” comes from!  

A few days ago, Apple decided to cancel its microLED project with ams-Osram, a development that took the display industry by surprise. It certainly surprised ams-Osram, which announced it will have to re-assess its microLED strategy and incur $650-900 million in impairment charges. It is currently unclear whether Apple's decision was to completely abandon microLED technologies, or if it still in the microLED race, perhaps with different technologies and suppliers. It is likely that Apple does not have any immediate plans to introduce microLED displays, though. In this article, we'll try to analyze the reasons which led to Apple's decision and the probable implications for the microLED industry. 

Summary:

• Apple cancels its microLED project with ams-Osram
• We estimate that the main reasons are Apple's technology choice and strategy
• MicroLED production will require next-gen technologies to succeed
• MicroLEDs still pose the best route for the future display technology, but companies will need to realign their strategies

Apple worked on microLED R&D since 2014, with a first target of producing microLED smart watch displays to replace the currently-used AMOLED displays. The Company had several partners, and decided to handle some of the process in-house. It seems as if even after almost 10 years of development and intensive R&D (estimates of Apple's total investment in microLED technology so far range between $1-3 billion USD), the technology was not ready for mass production - at least not at a price that Apple can accept.

Micro light-emitting diode (microLED) technology is the bright young thing in the display world, literally and figuratively. Its high luminance, sharp contrast, and vivid colors, among other attributes, make this one of the most dynamic emerging technologies for next-gen display applications. We’re just beginning to see what the future holds for microLEDs and their potential impact on display and imaging capabilities.

On the Technology Fast Track 

MicroLEDs have made rapid advancements since they were first submitted for patent in 1998. The Kansas State University researchers who developed these miniaturized versions of LEDs envisioned using them in sensors, detectors, and mini-displays. But now, in just under three decades, many major display leaders and emerging companies are racing to produce and integrate the technology in everything from smartwatches to TVs to automotive displays. 

US-based Terecircuits develops technologies and manufacturing processes for microassembly based on a new class of photo-chemical polymers. The company focuses on the development of a microLED photo-chemical mass transfer process. The company's CEO, Wayne Rickard, will give a talk at the upcoming MicroLED-Connect startup showcase event later this week, and he was kind enough to send us a short update on the company's technology and status, and his views on the microLED industry and market.

Hello Wayne, thank you for your time. Can you tell us a bit about Terecircuits, your technology and current status?

Terecircuits is a Materials Company with leading-edge know-how in synthesis, characterization, and delivery of proprietary encapsulants, polymers, and thin film coatings for the semiconductor and display industries. 

In general, our materials address the unique advanced packaging challenges of precision assembly: die-on-die, heterogeneous integration, 3D stacking, chiplets, SiC die attach, and – as it relates to displays - MicroLED mass transfer.
