MicroLED Microdisplays
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. Jade Bird Display) is the only ompany that commercially produces microLED microdisplays, mainly 0.3" VGA (640x480) monochrome (red, green and blue) displays. In 2023 JBD started shipping engineering samples of single-panel full-color 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.

Saphlux raises $43.5 million to bring its full-color microLED microdisplays to market
Saphlux has successfully completed its Series C funding round, raising 300 million Yuan (around $43.5 million USD)., from several Chinese investment funds and VCs.
Saphlux says that it will utilize the funds to accelerate its R&D and achieve mass production of full-color AR microdisplays.
Innovision starts mass producing the world's smallest microdisplay at 0.06-inch
China-based Innovision, developer of microLED microdisplays based on the company's vertically-stacked pixel (VSP) technology, announced a new 0.06" microLED microdisplay, the world's smallest microdisplay in production.
The Xinmou (also known as Chimo) M06 microdisplay offers a resolution of 540x280 (2.5 micron pixel pitch, 10,000 PPI) and ultra-low power consumption.
A spotlight on Plessey Semiconductors: a MicroLED Industry Association member
We’re pleased to feature Plessey Semiconductors, a UK-based leader in advanced photonics and microLED technology, as part of our series highlighting members of the MicroLED Industry Association.
Based in Plymouth, Plessey operates one of the few fully integrated microLED manufacturing facilities globally, bringing together design, epitaxy, wafer processing and device production on a single site. With over 70 years of engineering heritage and a growing commercial base across AR displays and optical interconnects, the company is focused on enabling the next generation of computing through photonic technologies.
We spoke with Phil Greenhalgh, Chief Technology Officer at Plessey, about the company’s technology, progress, and vision for the industry.
Mojo Vision secures a $17.5 million strategic investment to advance its microLED-based optical I/O technology
MicroLED microdisplay and optical I/O technology developer Mojo Vision, a MicroLED Industry Association member, announced that it has received a $17.5 million strategic investment from Future Ventures.
This follows the company's $75 million financing round last August and will help accelerate the development and commercialization of its micro-LED optical communication platform for next-generation AI infrastructure.
Kopin awarded a US government SBIR project to develop full-color, smaller-format MicroLED display technology for military applications
Kopin announced that it has received a Phase I Small Business Innovation Research contract from the U.S. Government to develop full-color, smaller-format MicroLED display technology for military applications.
The new SBIR project supports the creation of a second full color MicroLED display purpose-designed for several soldier-borne applications, marking this the second MicroLED focused award in the past six months for Army programs. Typically SBIR I projects represent around $150,000 - $300,000 in total funding.
Sitan raises around $14 million in its Series B3 funding round, reports on new design wins and commercial orders
China-based microLED display developer Sitan Technology has successfully closed its B3 funding round, raising almost 100 million Yuan ($14.5 million USD). Several investors participated in the round, including Xiamen Advanced Manufacturing No. 1 Fund, Xiamen Science City Mother Fund, Industrial Capital, and Longhua Capital.
This latest B3 funding round brings Sitan's total funding in its Series B rounds to over $30 million USD. The company will use the funds to accelerate its R&D and scale-up commercial production of microLED microdisplays for AR and automotive projection applications. The company currently operates a small-scale pilot line in Longhua, Shenzhen.
Researchers at the CEA Leti a sub micron microLED perovskite color conversion layer
Researchers at the CEA-Leti institute (a MicroLED Association member institute) developed green and red-emitting thin-film perovskite color conversion layers (CCLs) using pulsed laser deposition (PLD), that can be used in microLED microdisplays.
The researchers say that while QDs provide a good solution for color conversion microLED displays, they suffer from low absorption, which means that require a thicness of 3-10 micron, which is a challnge for very small microLEDs, required for microdisplays.
Polar Light and Finetech awarded a 1.1 million Euro project to develop dual-color microLED microdisplays
Pyramidical GaN microLED developer Polar Light Technologies has been awarded an EU Eurostars grant to develop a dual-color microLED microdisplay prototype deposited using the company's bottom-up mask-based deposition process.
The project, called 2ndGenMicroLED, will run for 18-month project, and has a total budget of 1.1 million Euro.
You can now buy microLED microdisplays at the OLED Marketplace
We are happy to announce that our popular OLED Marketplace website is now offering microLED microdisplays. MicroLEDs.
The first microLED that is on offer is a 0.12" VGA ultra-high-brightness monochrome display. It is available as either a display panel, or a complete display engine with optics (see image above). Hopefully we will add more panels and modules in the near future.
Meta gears up to engage in microLED Microdisplay mass production towards its 2027 microLED AR headset launch
A few months ago, we reported that Meta is in designing a new AR glasses product, that will be based on microLED panels, replacing the currently-used LCoS displays in the first-generation Meta Ray-Ban Display. Meta is said to aim to launch these microLED AR glasses towards the end of 2027.
Meta's First-Gen Ray Ban Display, LCoS based
Meta will not produce its own microLED, but the company is highly involved in the microLED display development. There's a new job opening at Meta (at Sunnyvale, CA), for an advanced manufacturing engineer to drive the ramp-up of RGB microLED chips at the company's key external partner.
