An interesting video surfaced, showing a small (reportedly 38-inch) microLED monitor prototype by Samsung, shown at a trade show:

We do not have any more information, but this is an interesting demo by Samsung. It is estimated that the monitor has a resolution of FHD (1920x1080), if Samsung is using the same tiles as the ones used in its TVs. It could be that this is not a tiled display, but we simply do not know at this stage.

Taiwan-based Innolux demonstrated new microLED display prototypes: a wide 187-inch microLED tiled display, a 9.6" flexible automotive microLED prototype and a transparent microLED.

Innolux did not detail much about these new prototypes. All of its microLEDs are based on blue microLEDs with quantum dot color conversion, and LTPS backplanes on glass substrates. 

SID's DisplayWeek is the world's leading display conference, gathering display professionals from all over the world. DisplayWeek will also host the 2024 annual meeting of the MicroLED Industry Association, where members will get together to share updates, connect with colleagues and launch new business relationships in a pleasant and welcoming setting.

Last year's DisplayWeek event marked the first MIA meeting, bringing together over 40 display professionals. We look forward to seeing our members soon!

Where will MicroLED technology take us? We’re only beginning to see all the possibilities it holds for display and imaging, but there are many reasons to envision a bright future. Ioannis (John) Kymissis, is the Kenneth Brayer Professor of Electrical Engineering at Columbia University and Chair of the Department of Electrical Engineering. The president-elect of the Society for Information Display (SID) shares his engineering expertise in display technology during a conversation that illuminates how MicroLEDs are leading the way toward unprecedented innovation.  

Q. What are some of the diverse applications of microLED technology across industries, and how does its versatility contribute to innovation?

A. Today, we are seeing microLEDs primarily considered for displays but there are also a range of applications outside displays that can benefit from the technology. Applications include 3D printing, communication, and use as illumination sources in structured backlights and cameras.

France-based microLED developer Aledia announced some breakthrough advances. The first one is a new <1.5 um microLED device that has the world's highest EQE of 32%. Aledia says that this new device leads to a Wall Plug Efficiency (WPE) of 320 milliwatts of visible light output per watt of electrical power input. 

As you can guess from the first subject, Aledia has successfully reduced its microLED pixel size to 2 um, or even below. Finally, Aledia says that it has reached a 99% DCI-P3 color gamut. 

Last week during Touch Taiwan 2024, AUO demonstrated several new (and not new) microLED display prototypes. The company released this short video showing the displays in action:

AUO showed its large-area (60") microLED displays, its automotive microLED solutions (including transparent automotive displays), a 30" real-depth 3D microLED display for entertainment applications, medical-grade displays and a 31" microLED display that is a single panel (not a tiled display) - which AUO says is the world largest.

In February 2024, ams-Osram announced that it's cornerstone customer (Apple) cancelled its microLED project, which will have dire implications for Osram's own $850 million 8-inch microLED epiwafer factory in Malaysia. Back then ams-Osram estimated that it will have impairment charges of $650 to $900 million and it will also likely to cancel or delay some of its investments in Malaysia.

ams-Osram now announced its plans and strategy following Apple's decision to cancel its project. It seems as if the company has decided to pretty much withdraw from the microLED display market, and the only remaining microLED development efforts will focus on automotive lighting products. ams-Osram now believes that microLED displays will primarily play a role in several smaller applications that also will scale slower and later than previously expected. We also believe that microLED displays will take a longer time to mature than some in the industry have expected.
