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:
Q-Pixel developed the world's smallest full color microLED pixel, and demonstrated a 10,000 PPI display
US-based Q-Pixel announced that it has developed the world's smallest full-color pixel (1 micron) and demonstrated a 10,000 PPI microLED microdisplay based on its proprietary tunable polychromatic microLED technology (which it brands as TP-LED).
Q-Pixel's technology enables 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, so this is fast progress only a few months later. Q-Pixel is a MicroLED Industry Association member.
The LAWK ONE microLED AR glasses to launch next month
The LAWK ONE is an AR headset based on dual microLED microdisplays, aimed towards outdoor 'adventure' use, that has launched a successful crowdfunding campaign. The HMD is set to start shipping in December 2023, with a launch price of $349.
The microdisplays are JBD's 0.13" VGA green monochrome microLEDs. LAWK ONE says that the displays offer up to 1,150 nits of brightness and a 30-degrees FOV.
A spotlight on the Fraunhofer FEP: a MicroLED Industry Association member

Reliance announces the JioGlass, a VR HMD based on dual full-color microLED microdisplays
India's Reliance announced the JioGlass, a VR HMD that is reportedly based on dual full-color FHD microLED microdisplays. This is an interesting product as it is the first one we are aware of that uses such commercial microLED microdisplays. It may be that these are actually OLED microdisplays, and the reports are inaccurate as is sometimes the case.
The JioGlass create a 100-inch virtual screen in front of the view, and the two microidsplays enable a 40 degrees FOV. The HMD connects via USB to any iOs or Android smartphone, or to a laptop. The HMD is designed by Tesseract, an India-based startup that was acquired by Reliance.
TCL announces the RayNeo X2 Lite smartglasses powered by full-color microLED microdisplays
TCL's RayNeo announced a new smart glasses product, the RayNeo X2 Lite, based on full-color 1500-nits microLED microdisplays. The company did not provide more details on the microLED displays, beyond saying that they will offer 3D images and a 30-degrees FOV.
The X2 Lite, powered by Qualcomm's Snapdragon AR1 Gen 1 Platform offer innovative AI-backed live translation, smart assistant, 3D navigation, and HD camera features. TCL expects to ship the product in Q3 2024.
