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.

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 reports from Japan, Sharp plans to split-off its display unit, in order to better focus on MicroLED technology development. The spin-off will also enable the new company to more easily secure funds, according to the report.

The new unit will be called Sharp Display Technology, or SDTC, and will be based in Kameyama. SDTC will focus on microLED technologies as its next-generation display tech, but in the meantime the company will also take over Sharp's existing LCD factories (and OLED R&D lines). The company aims to use the Hakusan LCD factory (recently acquired from JDI) for microLED R&D - and eventual production site.

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.

This article is a first article in a short series of articles that discuss the efficiency of microLED displays. And we start with the quantum efficiency of microLED chips.

LED devices are quite efficient. In the chart avovce, you can see that the efficiency (external quantum efficiency, or EQE) of a blue LED is around 70%. It is generally accepted that as LED chip size decreases, the efficiency of LED devices decreases as well.
