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 of these are already offering initial products on the market. Some examples of such companies include Plessey (owned by Facebook), Jade Bird Display and Lumiode. MicroLED microdisplays are not in mass production, although some companies are already sampling simple monochrome displays.
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.

The latest MicroLED Microdisplays news:
Focally unveils prototype AR glasses that use a full-color microLED display engine
India-based startup Focally unveils prototype AR glasses that feature several innovative technologies, including a full-color microLED based display engine.
Focally says that its Universe AR glasses will enable full-color and monochrome display modes, which leads us to believe that this display engine is built from 3 separate monochrome microLED displays, perhaps a similar design to Vuzix's display engine. Using waveguide optics, the company says that the display provides a 30-degree FOV. The company says that the display engine is the world's smallest and brightest, but does not provide any technical details.
MICLEDI and QustomDot to jointly develop color microLED microdisplays with QD color conversion
QustomDot and MICLEDI announced a joint development program to develop color microLED microdisplays using QustomDot's color conversion technology. The companies will demonstrate a microdisplay that offers a new architecture tailored for high-efficiency color conversion using stable RoHS-compliant QD materials. The displays will be produced using a high-throughput QD transfer and patterning techniques on micron-sized pixels.
QustomDot developed a patented method to produce high-quality and stable QD materials suitable for microLEDs. MICLEDI is producing its microdisplays on 300 mm wafers, and the company developed a new pixel architecture that has been optimized for high-aperture (>60% aperture at a 3μm pixel pitch) which the company says is a key requisite to achieve a high brightness with quantum dots.
JBD finalizes its Series A3 financing round
China-based MicroLED microdisplay developer Jade Bird Display secured its Series A3 financing round, co-led by Eight Roads and Lightspeed China Ventures. JBD raiased "several hundred million Yuan", which could mean anything from $30 million USD to $130 million.
In June 2022 it was reported that JBD is building a $92 million USD display production line in Hefei. The production line will have an annual capacity of around 120 million panels (likely JBD's 0.13" monochrome variant). JBD recently announced that it has developed a new red microLED emitter, that offers up to 500,000 nits of brightness at 2 micron sizes, and also that the company is developing native full-color microLED microdisplays.
MICLEDI launches microLED microdisplay arrays with integrated micro-lenses
Belgium-based microLED microdisplay developer MICLEDI launched microLED microdisplays with integrated micro-lenses, which it says it is a first for the display industry.
MICLEDI has already produces samples and test kits of blue microLED arrays, in addition to blue and green microLED arrays, and has shipped samples to potential customers. The company says that red microLED arrays will arrive in Q4 2022. The microLED arrays were produced in the company’s proprietary 300 mm manufacturing flow.
Report suggests both Samsung and LG started developing microLED microdisplays
According to a report from Korea, both Samsung Display and LG Display started to develop microLED microdisplay technologies.
Both companies have recently started to develop OLED microdisplays. According to the report, Samsung targets AR devices with its microLED microdisplay technology, while it targets VR devices with its OLED microdisplays. Samsung's microLED displays will achieve a resolution of 6,000 to 7,000 PPI (higher than its OLED devices).
Anycubic launches a portable 3D printer based on JBD's microLED UVA display
3D printer producer Anycubic announced a new consumer-grade pocket-sized 3D Printer, that is based on a small UVA microLED display, produced by JBD.
The display is JBD's standard 0.13" VGA display, but one that emits UVA emission. JBD also developed a custom projector for this new application. The extremely small, yet bright, display module, enabled Anycubic to design an extremely small printer (which is about the size of a 550 cl beverage can). The printer will be able to print details as small as 10 µm due to the high pixel density (>6000PPI) of the microLED display. The energy consumption during operation is only 6W.
JBD is developing native full-color microLED microdisplays
China-based MicroLED microdisplay developer Jade Bird Display announced that it is developing a native full-color microLED microdisplay. JBD is working to integrate InGaN and AlInGaP on the same chip, fabricated using conventional thin-film processes.
JBD says it developed a proprietary (and patented) technology in which the epitaxy layers were designed to be less susceptibility to edge effects, which helps to increase the display's efficiency. JBD's technology also enables effective mesa sidewall passivation. JBD refers to its technology as monolithic hybrid integration and says it can reach a PPI of up to 10,000 with a pixel pitch of 2.5 um.
Leyard starts producing microLED displays with Saphlux's QD color conversion technology
LED display market Leyard Optoelectronics announced that it developed the world's first mass-produced microLED display that uses quantum dots color conversion technology. Leyard collaborated with Saphlux (of which it owns around 12%).
Leyard adopted Saphlux's NPQD R1 micro LED technology, and have completed the development and testing of the display technology, and now it can mass produce NPQD-powered displays.
Mojo Vision's microLED-powered contact lenses used for the first time
AR developer Mojo Vision announced that it has performed the first on-eye test of its smart contact lens, powered by an MicroLED Microdisplay. The company's CEO, who was the first user, shares his experience in a blog post.
The display part of this system is based on a 14,000 PPI monochrome (green) microLED microdisplay, which is less than 0.5 mm in diameter.
