OLEDON developed a curved plane-source FMM technology that can be used to produce direct-emission 10,000 PPI OLED microdisplays

OLEDON says that it has developed a new curved plane-source evaporation shadow mask process that can be used for OLED microdisplay fabrication, with a potential density of 10,000 PPI (minimum shadow distance of 0.18um). Using this technology it will be possible to create direct-emission microdisplays.

In the video above, you can see the lecture OLEDON's CEO gave last month at iMID 2021, that explains the new technology.

INT Tech developed a 5,000 nits AMOLED microdisplay, is still on track for mass production in Q4 2021

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).

Is Facebook planning to use eMagin's dPd OLED microdisplay in its next-gen VR or AR device?

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.

eMagin reports mixed 2Q 2021 financial results

OLED microdisplay maker eMagin reported mixed quarter results for Q2 2021. Production issues and unexpected manufacturing tool downtime reduced revenues, but the company says it increased shipments to military, medical and other customers. Revenues in the quarter were $6.3 million (down from $7.7 million in Q2 2020). Net loss in the quarter was $0.3 million (but this includes a $2.6 million non-cash profit due to change in value of a warrant liability).

eMagin says it continued to make steady progress on the direct-emission microdisplay project, and remains on schedule to produce full-color prototypes this year. eMagin also reports it is ramping up production of its latest XLE technology (which still uses color filters) and has closed a major design win with a military customers for XLE OLED microdisplays.

On Seeya's OLED microdisplays status and plans

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:

eMagin reports its financial results for Q4 2020

OLED microdisplay maker eMagin posted its financial results for Q4 2020. Revenues for the quarter were $7.7 million (up from $7.3 million in Q3 2019) with contract revenue of $1.5 million reflecting continued work for a Tier-1 consumer company.eMagin XGA096 OLED-XL photo

Net loss for Q4 2020 was $3.7 million. For the full year 2020, eMagin reports revenues of $29.4 million, up from $26.7 million in 2019. The net loss in 2020 was $11.5 million.

eMagin reports its financial results for Q2 2020

OLED microdisplay maker eMagin announced reported its financial results for Q2 2020. Revenues reached $7.7 million, an increase of 44% from Q2 2019. Operating loss was $1.3 million (down from $2.8 million in Q2 2019).

eMagin says it continues to see strong demand for its microdisplays in the military market, and also in the medical market. At the end of the quarter eMagin's backlog was $13.3 million of products to be shipped in the next 12 months. Cash and equivalents at the end of the quarter were $11.5 million.

A look into eMagin's AR/VR dPd technology

In 2012, we first heard that eMagin is developing direct emission (or direct patterning, as the company calls it) OLED microdisplays. Fast forward into 2020, and the company is aiming to soon start producing such displays (it already launched its first such panel, see more below). In this article we'll look into the technology and the latest updates from eMagin.

All current OLED microdisplays on the market from all producers use a white OLED with color filter. This is a simple design, but it is wasteful in energy, as the filters block around 80% of the light, and in addition to achieve the white color one needs to use a blue OLED emitter (in addition to a yellow one, or red and green ones) - and blue is the least efficient color for OLED emission.
