The MicroLED Industry Association published today a new white paper, that is focused on monolithic microLED integration.

A major challenge in producing MicroLED displays is the transfer stage, also known as Pick and Place. This production step is responsible for transferring individual LEDs from the original wafer to the final display. In some cases, it is possible to (more or less) skip this stage and transfer the LEDs directly to the final display through a process called monolithic microLED integration.

This document will focus on such a process, discuss various options for its execution and examine the types of displays and applications it is suitable for. The white paper is published on the MicroLED Association's website, and is open to the public.

US-based Saphlux has developed a 0.39" full-color microLED Microdisplay, based on the company's NPQD color conversion technology. You can see a sample of Saphlux's T1-0.39 RGB display in the video below. 

Saphlux's first microdisplay offers a maximum white brightness of 250,000 nits, and a wide color gamut. The company is using high-EQE blue microLEDs (it has a partner that supplies the LEDs) and its NPQD technology achieves 67% photon conversion efficiency. The company's technology enables a pixel pitch of sub-2 microns. 

Market Research firm Trendforce predicts that microLED chip sales will reach $27 million in 2023, a growth of almost 100 compared to 2022 ($14 million). Trendforce says that the market is expected to actually accelerate its growth, and grow at a CAGR of 136% from 2022 to 2027, reaching $580 million in 2027. 

Of course not just the LED chip market will grow - the entire ecosystem, including production equipment, backplanes, and more.

In March 2020, Facebook (now Meta) signed a deal with UK-based MicroLED microdisplay developer Plessey Semiconductor to dedicate all of Plessey's microLED manufacturing operations to support Facebook with its own product development. Facebook pretty much acquired Plessey's microLED operations with this exclusive deal.

Facebook hoped to utilize microLED microdisplays in future AR headsets. According to a new report, the company has decided to use LCoS microdisplays for its first consumer AR device, codenamed Artemis, which will be released (if all goes according to plan) in 2027. It seems as if the development based on Plessey's technology and processes did not progress as expected, and Meta did not manage to develop high brightness microLEDs or a process with satisfactory yields.

We're happy to interview 3D Micromac, as part of our series of interviews with MicroLED Industry Association members. Germany-based 3D-Micromac is the industry leader in laser micromachining and roll-to-roll laser systems. The company offers laser equipment for µLED forward transfer, lift-off and repair process steps - ready for high volume production.

Hello, can you introduce your company and technology?

Frank Richter (Head of Sales at 3D Micromac): 3D-Micromac has established itself as a leader in laser micromachining and a pioneer of new production technologies for various industries for the last 20 years. This especially applies to the excimer and ultra-short pulse laser technology.

We have extensive experience applying innovative laser technology to new and emerging applications to support their volume-production requirements. For MicroLED production, ultra-high precision in combination with the highest reliability and stability is needed. These are core competencies of 3D-Micromac.

Our product portfolio includes several laser-based system solutions for various manufacturing steps in the MicroLED production process. All systems offer integrated process control and monitoring to assure stable and reliable operation, thus enabling high throughput and low yield losses.

Virtual reality (VR) and augmented reality (AR) have received a lot of media buzz over the past few years. They promise benefits for applications are as diverse as gaming, healthcare, training, engineering, architecture, interior design, travel, defense, and even product marketing. But today, VR/AR still hasn’t had a significant impact on most people’s lives.

Two main reasons for this are VR/AR headset quality and cost. Specifically, quality includes factors like image brightness, resolution, field-of-view, and electronic characteristics like speed and power consumption. Plus, practical considerations, including headset size, weight, and battery lifetime are also important. And cost means bringing down headset prices low enough to make them accessible to most consumers.
