OLED displays are excellent for driving AR glasses and devices - as they provide high quality images, low power consumption and high brightness (although not as high as MicroLED displays).
Laser cutting processes of glass materials based on filament technology have been increasingly adopted in industrial applications. Besides standard glass thicknesses ultra-thin glass offers exciting opportunities for further improvements of new devices.
The main reason for this is the perfect match of material properties like mechanical resistance and flexibility as well as optical performance. The required machining processes to perform perimeter cutting as well as structuring and via drilling are confronted with high quality requirements.
According to a report from Korea, Facebook recently hired a large number of OLED engineers, in Korea, through Facebook's Reality Lab. The company is now hiring more OLED experts to work at its Reality Lab US offices.
Facebook new job openings includes many roles in OLED display technologies. The company does not aim to start producing OLED, of course, but to secure technology to develop innovative OLED displays and applications in VR and AR devices.
The new 0.7-inch INT Tech uNEEDXR display is a direct-emission display that features a brightness of over 5,000 nits, 3147 PPI and a low power consumption (less than 500mW@5000nits).
OLED microdisplay maker eMagin has been developing direct-emission OLED microdisplay (also called directly-patterned, or dPd) for many years, and is considered to be the leading company - the closest one to commercialize such a display. A dPd will enable much higher efficiency/brightness compared to current designs based on color filters.
MicroLED displays are exciting to many, as the technology seems to be the front runner for the next-generation display of choice in many market segments - from AR/VR glasses through wearables to TVs and IT displays.
The MicroLED industry though, even after billions of dollars spent on R&D, is still at a very early stage. Production costs are high, processes are not reliable enough, and there are several technical challenges to overcome before production can begin (except for some niche areas such as ultra large-size premium TVs).
OLED microdisplay developer Seeya Information Technology was established in 2016, and in 2017 it started building a $300 million OLED 300 mm microdisplay production line. Seeya's fab is now in operation, with a yearly capacity of around 20 million displays (monthly capacity of 9,000 300 mm wafers).
Seeya quickly became a prominent display maker, who's currently producing high performance displays to global customers. The company says it's currently the world's largest OLED microdisplay maker by volume. Seeya's current standard displays include:

This year at Displayweek 2021, LGD is showing the same display again, this time it reveals it has a brightness of over 5,000 nits (in 2020 the company said the brightness was "over 4,000 nits"). LG says that OLED microdisplays will find a market in VR and AR applications, as the displays outperform mobile AMOLED displays.
The South Korean government launched a new project which aims to develop new technology that will enable the production of Oxide-TFT that support 1,000 PPI OLED panels. The project, led by Samsung Display, will hopefully conclude by 2024.
Samsung plans to develop higher-efficiency Oxide-TFTs - in fact ten times faster than today's Oxide-TFTs. The new technologies will reduce the power consumption and production costs of the TFTs.
The Korean government launched a new project that aims to develop technologies for the production of OLED microdisplays for AR applications.
The new project, organized by the Korean Ministry of Trade, Industry and Energy is led by AP Systems. The project aims to produce a direct emission OLED microdisplay with a resolution of 4,000 PPI by 2024.
