OLED microdisplay maker eMagin announced that EO System Company (EOST) , an established electro-optical devices defense supplier, has been using the company's range of OLED microdisplays in its products.

EOST is using eMagin's displays in its snipers thermal weapon sights, thermal imaging systems and binocular systems for surveillance. The company says it has deployed over a dozen different eMagin OLED microdisplays over the years. eMagin says that its current backlog to EOST is over $1 million.

Researchers from the Polish Academy of Sciences (PAS) and from the Silesian University of Technology have developed new OLED emitter materials based on aromatic electron-donating and -accepting moieties bridged by an antiaromatic seven-membered ring.

The researchers say that the new design of its N-doped PAHs is very flexible, and their properties are very responsive to the choice of the electron-accepting group. The researchers can thus can tune the emission mechanism between TADF emission and room temperature phosphorescence (RTP) emission, which gives high degree of control over the emission profile.

The Elec reports that Samsung Display is currently using a transparent tape (OCA) to attach the OLED panel to the cover glass, in its foldable OLED production process. The company has decided to switch to liquid transparent adhesive (OCR) in order to reduce production costs.

The cover glass lamination is performed at Samsung's module factory, in Vietnam. The company will make the necessary investments in the plant to enable it to use OCR technology.

LG Display has deployed 38 55" transparent OLED displays at a new bakery in Korea. This is a "futuristic" flagship branch of Korea-based Paris Baguette, in Pangyo. LG says that in this new bakery, new products and services can be experienced first, and this goes in line with the adoption of the transparent screens.

This is the largest ever transparent OLED installation, where these OLEDs are used to create a giant digital signage system. The screens are used in the store's entrance, as a smart partition between the baking station and the store, as transparent art wall, and also as transparent signage on the windows, on the bread stand.

The Korean Supreme court put an end to a years-long legal battle between LG Display and Samsung Display, saying that SDC's employees and a chief executive of one of LG's suppliers are not guilty in IP theft.

The supreme court upheld the original ruling and dismissed the appeal. The case revolved around LGD's face seal encapsulation technology for OLED displays. The main issue in the legal case was whether leaked LGD documents were trade secrets. The employees and executives were first found guilty, but at a higher court they were found innocent as it was decided that the information was already widely known in the industry.

OLED microdisplay developer BCDTEK is embarking on a new project to construct a 12-inch OLED microdisplay production site in Huainan, China. The new fab will have a production capacity of 20,000 monthly substrates.

The total investment in this new fab will reach 6.5 billion yuan (around $970 million USD), with the first phase (4,000 substrates per month) estimated at $210 million USD (1.5 billion Yuan). The company has raised funds from China Micro Semiconductor and Shanghai Wusheng Electronics. 

In 2021 The Korean government launched a new project that aims to develop technologies for the production of OLED microdisplays for AR applications. The project is led by AP Systems (APS Holdings), and aims to produce a direct emission OLED microdisplay with a resolution of 4,000 PPI by 2024.

According to reports from Korea, APS Materials has managed to develop a 1,000 PPI FMM mask, and is now building a new R&D line that will be used to produce direct emission OLED microdisplays using FMM technology. The new APS production line will include OLED deposition and encapsulation.

OLED microdisplay maker eMagin has been awarded a $2.5 million US Army contract towards a high-brightness, full-color direct-emission OLED microdisplay prototype project. The project includes the development of manufacturing process technologies

The prototype that eMagin will develop will be used in AR systems that provide both sensor and tactical data to soldiers.
