MicroLED technology is a perfect fit for microdisplays - as it can offer extremely bright and efficient displays with very fine pixel pitches.
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.
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.
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.
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:
This article is the second article in a short series of articles that discuss the efficiency of microLED displays. Our previous article discussed the quantum efficiency of microLED chips - with a conclusion that these can be quite efficient.
This article will look at the entire microLED display, and also compare it to current LCD and OLED displays. After all one of the main advantages of microLED displays is the increased efficiency (and brightness) compared to current displays. Most people assume that indeed microLEDs are much more efficient than OLEDs and LCDs.
In May 2020, China-based MicroLED microdisplay developer Jade Bird Display announced a new 0.13" VGA microdisplay - which it says is the world's smallest microdisplay. JBD today announced that next month it will stat selling these displays.
The JBD4UM480P microLED display is a monochrome 640x480 0.13-inch display, that offers a brightness of 2 million nits (green), 200,000 nits (red) or 150,000 nits (blue), with a power consumption of a few hundred milliwatts under average operation conditions.
Compound Photonics announced a new partner ship with Axus Technology to help accelerate MicroLED microdisplay development. The two companies will integrate critical wafer-scale processes needed for mass-production scale of CP's microLED displays.
Specifically, Axus will deploy its Capstone CMP system with integrated post-CMP clean to enable wafer planarization and surface preparation process solutions for successful wafer-scale bonding of microLED wafers to high-performance CMOS backplanes.
Yole Développement (Yole) says that the microdisplay market is set for impressive growth in the next few years. By 2025, the total market will reach $4.2 billion in revenues (CAGR from 2020 to 2025 at 100%), while microdisplays for AR headsets will generate $1.8 billion.
This optimistic forecast has a warning though - it all depends whether next-generation display technologies will deliver on their promises - and whether actual use-cases will be found and commercialized.
According to Digitimes, Foxconn is developing its own AR glasses product, which it hopes to launch in 2022. The report says that Foxconn will first target smart retail, factories and medical care for its AR system.
Digitimes also says that these AR glasses will be based on microLED microdipslays, which are being developed by EOSRL (part of ITRI). EOSRL apprantly developed its own blue-light 5-micron LED technology with QD color conversion that enable it to produce 2000 PPI displays. First displays are expected to be produced in Q1 2021.
Aledia to setup a 140 million Euros GaN-On-Si microLED production line, start making microdisplay by 2022
France-based 3D GaN LED developer Aledia announced that it plans to establish a 140 million euros LED production fab in Champagnier, near Grenoble in France. The plan is to start LED production by 2022 - and by the company will also finalize its microdisplay production process and will start offering microLED microdisplays.
Aledia developed a microLED production process, based on a unique 3D architecture using GaN-on-silicon nanowires (branded as WireLED).
Vuzix announced that it is developing its next-generation Smart Glasses, that will be powered by microLED microdisplays and other advanced technologies. The first such glasses are expected to become available in 2021.
Vuzix is developing a wide range of devices, ranging from "reasonably priced consumer-facing product" to a higher end enterprise version with built-in cellular connectivity. Vuzix says that the new advanced waveguide optics and binocular displays will enable a larger field of view and an enhanced user experience. Vuzix is developing solutions based on both monochrome and full-color microLEDs.
According to reports from Japan's Nikkan Kogyo Shimbun, Sharp is developing MicroLED microdisplays, with an aim to mass produce such panels in 2023 or 2024 for AR and VR applications.
Sharp apparently already developed two prototypes, including a 0.38" 1053 PPI color one and a 0.13" 3000 PPI blue display. The color display uses blue microLEDs with Sharp's own proprietary color conversion QD technology.
