During Sony's Technology Day, the company unveiled a new VR headset prototype based on a new 4K OLED microdisplay panel, which was unveiled for the first time.
Sony reports that the new microdisplay features very low latency, with a response time of

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.
Taiwan-based INT Tech announced that it has produced new AMOLED microdisplay samples at its $143 million fab in Taizhou in Zhejiang province, China, and the company is still on track for mass production in Q4 2021.
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.
In the past eMagin reported of several leading companies that have licensed the technology and/or are working with the company towards the design of custom dPd OLED displays for future AR/VR products. In 2017 for example eMagin reported of a Tier-1 CE company that licensed its dPd tech, and in 2020 the company said it started a new consumer-related AR development project for a next-generation display for a Tier-1 customer.
In 2016 Sony launched its successful Sony Playstation VR Headset, with its 5.7" FHD (1920x1080) AMOLED display. The company is getting ready to release an updated version, and during its latest developer summit, it revealed some initial details.
The new VR headset will feature OLED displays, with higher resolutions - there will be dual 2000x2040 displays. The field of view is also improved to 110-degress (up from 100 degrees in the original PSVR).
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:

Last year at SID Displayweek 2020 LG Display unveiled a new OLED microdisplay, branded as OLEDoS. LGD's display was a 0.42" 1280x720 (3,500 PPI) panel that uses a color-filter based design.
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.
