China-based microLED microdisplay developer JBD announced that it has completed a major upgrade of its microLED microdisplay mass-production architecture, and has shifted from 4-inch manufacturing to a 12-inch reconstructed wafer platform. This is a sort of medium step before full 12-inch LED epiwafer deposition.

JBD says that the current wafer mismatch between the 4-inch LED wafer and the 12-inch silicon backplane wafer has become a key factor limiting cost efficiency and substrate utilization. JBD has integrated its "die-to-carrier-to-wafer" bonding scheme into its volume production architecture. Under this process, small-format epitaxial wafers are diced into individual dies, followed by pre-bond inspection and sorting to identify and remove defective chips at an early stage. Qualified dies are then reconstituted onto a temporary 12-inch carrier substrate with high placement accuracy and uniformity, creating a reconstructed epitaxial wafer for subsequent wafer-level bonding with a matching 12-inch silicon backplane.

MicroLED microdisplay developer Innovision showcased its latest microLED displays, along with a selection of monochrome and RG (red+green) polychrome waveguide modules, and headsets that utilize the company's displays, at SID Display Week 2026 last week.

The main products on display was the Chimo M06 microdisplay, a 0.06-inch microdisplay (the company says that this is the smallest microdisplay in production) that offers a 540x280 resolution (2.5 micron pitch), 240Hz refresh rate with red, green or blue versions. The company also demonstrated the Chimo M06E display engine based on this microdisplay. Chimo M06E achieves a compact lens volume of just 0.03cc and weighs only 0.08g. Compared to the previous generation's 0.15cc optical engine, this substantial reduction in volume frees up more space for AR glasses design, better meeting the demands of lightweight daily wearables.

The MicroLED Industry Association published a new white paper that provides a discussion on automotive HUDs, and microLED solutions. The white paper is openly available to download here.

Automotive HUDs present a promising market for microLED display engines, with high performance requirements, including high brightness, durability, and design freedom. This white paper introduces automotive HUDs, discusses display and system considerations, and details the different display technologies suitable for HUDs.

The full edition (available to association members only) also includes a discussion on microLED based solutions, insights on microLED HUD displays, roadmaps and challenges. 

Researchers at the The University of Osaka, in collaboration with Ritsumeikan University have shown how growing europium-doped gallium nitride (Eu-doped GaN) on a semipolar crystal plane dramatically improves red light emission. 

The researchers say that EU-doped GaN is a promising next-generation microLED material platform, as it provides narrow-linewidth, wavelength-stable red emission based on intra-4f-shell transitions of Eu ions. In this research, it was found that growing these on a semipolar crystal plane selectively promotes the formation of highly efficient Eu luminescent centers, resulting in red emission intensity more than 3.6 times higher than that of a conventionally grown material.

Samsung has been developing and supplying ultra-large-area tiled emissive microLED TVs, targeting both commercial/signage and residential applications for many years, and it has recently started to ship RGB microLED-backlit LCD TVs. 

According to a report from Korea, the company is adjusting its microLED TV production business, looking to increase profitability and product popularity - which basically means that it is likely to focus less on ultra-large premium TVs, and more on consumer-level microLED backlit LCDs. It is clear that microLEDs are not yet ready to enable mass-produced emissive TVs, even at a premium, as prices are simply too high and there are many improvements and challenges to overcome before this is possible.  

TrendForce says that microLED-based optical communication, offering low power consumption and low error rates, is emerging as one of the three major short-distance, high-speed intra-rack transmission solutions for scale-up data center networks, alongside active electrical cables (AEC) and VCSEL-based near-packaged optics (VCSEL NPO). 

The high demand for AI datacenter communication solutions, will drive fast growth, and Trendforce projects that microLED co-packaged optics (CPO) will start to scale up in the second half of 2028, and will quickly ramp up to $848 million by 2030. 

Toray Research Center (TRC) is hosting an open online webinar, with lectures focused on microLED displays and OLED materials analysis and evaluation. TRC, which supplies technical analysis and support for R&D and manufacturing, invites you to attend the online lectures at no cost to gain a deeper understanding of microLED technologies and the analysis of display devices. You can register to view the lectures here - note that the recordings will be available until June 1st.

The first lecture discusses new analytical technologies for morphology, structure and property evaluation. During the lecture, TRC researchers will discuss the center's In-Situ Heating TEM system, and how it enabled the reproduction and visualization of the bonding strength enhancement process induced by thermal treatment. Other topics in this lecture will include temperature- and humidity-controlled  nanoindentation measurements, AFM-IR for nanoscale functional-group and structural analysis, and the analysis of metal-organic complexes in liquid.

The countdown is on for MicroLED Connect 2026, returning to the High Tech Campus in Eindhoven on 16-17 September. If you’re planning to attend, now is the ideal time to secure your place, with ticket prices set to rise in early June.

MicroLED Connect 2026 will once again bring together the global microLED ecosystem for two days of insights, collaboration, and innovation. From display giants to emerging startups, the event offers a unique opportunity to engage with the companies and researchers pushing microLED technology toward large-scale commercialization.

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.

MicroLED display developer Sitan Semiconductor announced a strategic partnership agreement with Changelight, LED epiwafer producer, with a strong presence in the automotive-market.

It seems as if this partnership is mostly focused on automotive microLED applications. The two companies aim to collaborate and co-develop high-performance microLED for automotive displays. Chagelight will likely contribute its high-performance microLED sapphire epiwafer and chip capabilities, while Sitan will be in charge of developing automotive displays based on these microLEDs chips.
