Samsung Display is demonstrating its first microLED wearable display prototype, at CES 2025. The company did not share many specifications, beyond saying that the brightness is 4,000 nits peak, which makes it brighter than the 3,000 nits Apple Watch OLED display.

Samsung started developing wearable microLED displays back in 2023, hoping that Samsung Electronics will release a first product by the end of 2025. This was delayed, but it is great to see SDC showing this display publicly for the first time.

AUO is showcasing its latest microLED technologies at CES 2025, focusing on automotive solutions, under the Smart Cockpit 2025 platform. The company is demonstrating several novel applications, enabled by the transparent and flexibility of microLED displays.

So first up we have the Virtual Sky Canopy, and XR Interactive Window technology - both of these adopt the use of tiled transparent microLED displays to embed within the car windows and windows, and extend the display beyond the normal instrument cluster and information displays.

MicroSolid Printing pioneer VueReal is going to unveil several new technologies and products at CES, as the company gets ready for microLED display commercialization. VueReal wants companies to take advantage of the unique properties of microLED displays (mainly the customized production process and the high transparency and high brightness) and this year it will focus on new applications that can be enabled only by microLEDs.

First up, VueReal is launching new microLED Design Reference Kits to enable product designers to buy display samples and integrate into new designs. The first kit will provide microLED-powered lighting panels. These resemble OLED lighting panels - area lighting that is uniform. But unlike OLEDs, microLEDs will provide high brightness, long lifetime, and reduced costs. These are basically monochrome simple displays, and VueReal will offer either in native colour (R, G, B) or phosphor coated (white, red, amber).

Researchers from Hong Kong University of Science and Technology (HKUST) have developed a deep-ultraviolt (UVC) microLED display array for use in lithography machines. The researchers say that the array feature enhanced efficiency, and is viable as a source for low cost maskless photolithography.

The researchers, in collaboration with the Southern University of Science and Technology, and the Suzhou Institute of Nanotechnology, have built a maskless lithography prototype platform and used it to fabricate the first microLED device by using deep UV microLED with maskless exposure, improving optical extraction efficiency, heat distribution performance, and epitaxial stress relief during the production process.

Researchers from France's CEA-Leti and CNRS institutes have succeeded in growing highly efficient red, green and blue InGaN submicron microLED nano-pyramids.

The researchers have deposited the nanopyramids by using an MOCVD-based technique, and using nanoselective area growth using an in-situ patterned graphene on SiC as a mask. The researchers report that these microLEDs offer high efficiency with the red microLED offering very regular quantum wells emitting at 620 nm with an In content up to 40%.

A year ago Foxconn announced a strategic partnership with Porotech to co-develop microLED microdisplays, targeting AR, wearable and other applications. Foxconn said that this partnership will utilize Porotech's Dynamic Pixel Tuning color-tunable GaN-on-Silicon microLED technology and Foxconn's technologies in semiconductor wafer manufacturing, packaging, IC drivers, CMOS backplanes, module assembly and system assembly.

According to a new report from China, Foxconn plans to build a microLED epiwafer production line in Taichung, Taiwan. Foxconn aims to start mass production by the end of 2025.

China-based MicroLED microdisplay developer Jade Bird Display have developed a full-color microLED microdisplay that achieves a brightness of 2 million nits (white-balanced).

JBD says that its Phoenix series RGB microdisplays offer a pixel pitch of 5 micron, an ultra-thin stack of less than 5 micron, native RGB emitters and high color fidelity. JBD hopes to commercialize its full color microdisplays in Q3 2025. 

A state-of-the-art GaN production facility in Europe has been put up for sale. As per the seller, the facility offers extensive GaN capabilities as well as a track record of doing high-volume CMOS production. The facility include 40,000 sqft of cleanroom space, and about 200 process tools (80% of which are 200 mm). This facility is currently engaged in R&D development and low-volume micro LED manufacturing with existing profitable revenue. The identity of the seller has not been published.

The sell has exclusively retained ATREG to handle the sale. ATREG says that the facility is offered with a comprehensive IP portfolio, over 250 skilled employees (of which 110 are engineers), and specialized capabilities in MOCVD, CMP, and wafer bonding. In addition to the current micro LED capabilities, the fab is suited for GaN power devices, advanced photonics, GaAs processing, and MEMS/sensors manufacturing. The fab has received significant investment over the past five years, including sub-fab upgrades, cleanroom expansion, utility improvements, and other facility upgrades.
