MicroLED technology is a next-generation emissive display technology that promises highly efficient and bright displays that offer superior image quality with infinite contrast and a wide color gamut. MicroLEDs are an excellent fit for microdisplays - as it can offer extremely bright and efficient displays with very fine pixel pitches.
Microdisplays are very small displays (usually under 1-inch) used in near-eye applications such as AR glasses, camera view finders and rifle sights. Most microdisplays on the market are either LCoS or OLED displays.
MicroLED Microdisplays
Many companies are developing high-end MicroLED microdisplays, and some are introducing initial products on the market. In 2020, JBD became the first company to commercially produce microLED microdisplays - 0.3" VGA (640x480) monochrome (red, green and blue) displays. In 2023 JBD started shipping engineering samples of single-panel RGB microLED microdisplays.
Microdisplays use a high-end silicon backplane, and microLED microdisplays can be produced using a monolithic process - which means that the LEDs can be fabricated directly on the silicon wafer, or transferred to it in a process that is simpler compared to a TFT-glass transfer process.

Q-Pixel developed an active-matrix 6800 PPI microLED microdisplay based on its colot-tunable LED technology
US-based Q-Pixel announced that it has developed a new 3K x 1.5K, a 1.1x0.6 cm (6800 PPI) microLED microdisplay. Q-Pixel says that this is the world's highest resolution color microdisplay - but they actually mean the highest density full-color microdisplay.
Q-Pixel's technology is based around a single-pixel color-tunable microLED device, and the company's displays are produced using a monolithic process. In May 2023, the company announced a 5,000 PPI full-color microdisplay. In fact, later in 2023 the company announced a 10,000 PPI microLED microdisplay, but the 10,000 display was a passive-matrix microdisplay, and the newly announced display is an active-matrix one.
MICLEDI closes its Series A funding round to accelerate its microLED microdsiplay development
Belgium-based microLED microdisplay developer MICLEDI announced that it closes its Series A Funding round, to accelerate its development of high performance microLED arrays. VCs that participated in this round include imec.xpand, PMV, imec, KBC and SFPIM.
MICLEDI did not disclose the funding it received, but it did say that total funding in the company to date is nearly $30 million. In 2021, the company raised 7.1 million Euro, and in 2020 MICLEDI raised 4.5 million Euro in its Series-A round (which is now referred to by MICLEDI as its seed round, together with the 2021 round). Following its 2020 round we talked with the company's CEO who explains the company's technology and goals. If our calculation is correct, this new Series A round totaled around $17 million.

A spotlight on VueReal: a MicroLED Industry Association member
We're happy to interview Reza Chaji, CEO and founder at VueReal, as part of our series of interviews with MicroLED Industry Association members. Canada-based VueReal developed a unique microLED display production process (which it refers to as a MicroSolid Printing Platform) and the company now offers a turnkey platform that enables its partners and customers to develop a custom display and fabricate it at VueReal's own pilot production line.
Hello Reza, can you introduce your company and technology?
From the outset, we recognized that microLED solutions should address the formidable challenges of developing smartphone microLED displays to pave the way beyond niche markets. Consequently, our focus has been on developing scalable and cost-competitive technologies tailored for high-volume applications. This strategic approach positions us effectively to address the smartphone sector soon and opens doors to other markets.
VueReal's fundamental technological innovation lies in our transfer solution with unique printing attributes, microSolid Printing. This groundbreaking solution boasts distinct advantages over lasers and pick-and-place methods.
STRATACACHE to integrate Lumiode's backplane deposition technology in its microLED fab in Eugene, Oregon
US-based signage leader STRATACACHE announced that it has signed a strategic research and IP licensing agreement with US-based Lumiode that will enable STRATACACHE to integrate Lumiode's technology in its upcoming E4 microLED production line in Eugene, Oregon.
Lumiode's technology enables the deposition of an active matrix backplane directly on the LED structure. Lumiode's technology enables the production of both large-area displays and small microdisplays, and it is likely that STRATACACHE is interested in the former.
Porotech signs up PSMC to commercialize its microLED displays
Porotech announced a strategic partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corp. (PSMC), to bring Porotech's microLED displays top market.
