Lumileds, in collaboration with researchers from the Eindhoven University of Technology have managed to significantly improve the directionality of microLED emission, using metasurfaces.

The researchers embedded a metasurface consisting of nano-sized disks within the p-contact layer of the MicroLED device, and stimulated collective resonances with emitting dipoles in the active region. The enhanced light outcoupling and radiative recombination led to notable improvements in LED efficiency. Additionally, the design of the nanostructure lattice was tailored to manipulate the far-field emission pattern of the LED. The team successfully showed that on-axis candela can be doubled for comparable LED output.

AUO announced that it will showcase new microLED display prototypes and technologies at Touch Taiwan next week. First up, the company has demonstrated a 42-inch single module microLED, which is said to be the world's largest (beating AUO's own record at 31-inch from 2024). The module offers a brightness of up to 1,000 nits, and AUO is showing a 127-inch tiled TV made up from these new modules. AUO will also show a full range of microLED TVs, developed in collaboration with Samsung Electronics. These TVs are based on AUO's MicroLED backplane technology.

Another new display will be the world's thinnest 17.3-inch dual-sided transparent Micro LED display.  AUO did not detail any more information on that display - or just how thin is it. Among its use cases are interactive, first-class cabin interfaces that facilitate seamless communication between passengers and flight attendants via real-time translation on a transparent screen. The display also has use in commercial advertising, home decoration, points of sales and many other fields where the display can increase tech and style while also transmitting information.

During CES 2025, Samsung Electronics demonstrated a 98-inch 8K microLED-backlit LCD TV, branding it as RGB MicroLED TV. This is not a true microLED TV, as it is not emissive, but unlike other LED- and miniLED- backlit LCDs, this one uses smaller red, green and blue microLEDs.

Samsung now says that it plans to launch this new TV, at a size of 115-inch, later in 2025. This will be Samsung's most premium LCD TV. One of the main advantages over its current miniLED-backlit LCDs, is the use of red, green, and blue microLEDs, rather than blue miniLEDs and color-conversion (QD and phophors) technology to create white-emitting LEDs. This should enable a larger image gamut. The microLEDs may also contribute to a higher contrast compared to the bigger miniLEDs, as there will be better dimming zone control.

Counterpoint (DSCC) released its latest display equipment spending forecast, for OLEDs, LCDs and MicroLEDs. The total spending in the period 2020-2027 will be $77 billion. Most of the spending will be focused on OLED equipment from 2025 to 2027.

Not surprisingly, Counterpoint does not see any meaningful spending on microLED equipment throughout their forecast period - apart from a small investment in 2023-2024, which could be spending by Apple's partners in the cancelled microLED watch project. 

Touch Taiwan, one the world's leading display conferences, will take place next week in Taipei. The MicroLED-Info team will attend this year's event, and we're looking forward to seeing new display technologies, with a focus on microLED displays of course, new products and demonstrators and meeting up with industry leaders!

If you plan to come to the event, do contact us and we will be happy to schedule a meeting. We're really looking forward to this event, to meeting our display industry friends, and to host the special MicroLED Association dinner meeting on April 15.

Pyramidical GaN microLED developer Polar Light Technologies announced that it has successfully closed a fully subscribed funding round $3.4 million, from both existing and new investors.

Polar Light says that thanks to these new funds, it now plans to bring its microLED technology to market in 2026. The company also plans to complete a larger financing round in 2026 to support full-scale market entry.

The MicroLED Industry Association is inviting its members to a special dinner during SID Display Week 2025 in San Jose, California. The dinner is kindly sponsored by Smartkem and promises to be an unforgettable evening of good food and networking.

This dinner will provide a unique opportunity for members to connect in a friendly environment, share insights, and build meaningful relationships within the industry. We would like to thank Smartkem again for sponsoring this event!

Avicena, a developer of microLED-based chip-to-chip interconnects, launched its scalable and modular LightBundle interconnect platform. 

LightBundle supports > 1Tbps/mm shoreline density and extends ultra-high density die-to-die (D2D) connections to > 10 meters at class leading sub-pJ/bit energy efficiency. Avicena says that its microLED based solution will enable AI scale-up networks to support large clusters of GPUs across multiple racks, eliminating reach limitations of current copper interconnects while drastically reducing power consumption.

Ennostar Inc, that recently announced a restructure to merge Epistar and Lextar into a single company, says that it has recently achieved several significant breakthroughs in its microLED technology. 

First of all, Ennostar said that it has managed to improve the blue and green microLED light efficiency by 10% to 15%, and dramatically improve its red light efficiency by 90%.
