Samsung Display developed a 18.2" 350 nits ink-jet printed OLED panel

Samsung Display has developed a 18.2" 2560x1440 202 PPI inkjet-printed OLED display, that features the highest current efficiency of any inkjet-printed OLED, with the brightness at 350 cd/m2 (full white).

Samsung Display says that the high brightness was achieved by tuning the top-emission device structure with high performance soluble materials. The high pixel resolution was achieved by modulating the jetting waveform for ejecting ink drops and improving the drop placement accuracy by selecting the right ink formulations in terms of viscosities and surface energies.

UDC establishes a subsidiary to advance OVJP commercialization

Universal Display established a new subsidiary, called OVJP Corporation, that will advance the commercialization of UDC's OVJP OLED TV manufacturing technology.

OVJP stands for Organic Vapor Jet Printing, and the basic idea is to use a gas-stream based process that resembles ink-jet printing but one that uses evaporation OLED materials. In an OVJP process, the OLED materials are evaporated into a carrier gas that delivers them to a jet engine for direct printing of patterned OLED layers.

DSCC - OLED material sales will grow from $951 million in 2019 to $2.69 billion in 2024

DSCC updated its OLED material market estimates, saying that AMOLED stack material sales will grow from $951 million in 2019 to $2.69 billion in 2024 - a CAGR of 23%. These new estimates take into account DSCC's reduced input area forecast due to the slowdown in demand cased by the Covid-19 pandemic.

DSCC says that incremental improvements in material utilization and price reductions, material costs per square meters will decline in the future. The unyielded cost of producing a square meter of a WOLED TV panel will decline from $95.21 in 2019 to $56.11 in 2024.

The Fraunhofer FEP Monarch flexible transparent OLED lighting kit - hands on review

In 2018 the Fraunhofer FEP institute announced it is starting to offer a design kit that includes several flexible and transparent OLED lighting panels. The Monarch Kit includes several colored butterflies samples, and the researchers were kind enough to send us one such kit for a short review.

So first of all, these OLEDs look beautiful. They shine a beautiful uniform colored light and are very nicely done. There's not much functionality, but it shows the potential of flexible OLED lighting quite nicely.

The Korea government to establish a $470 million OLED R&D center

The South Korean government announced a seven-year project to establish an OLED R&D and manufacturing facility in Cheonan, South Chungcheong Province.

The Korean government will spend 528 billion Won (around $468 million USD), it's largest ever R&D project, to build the R&D center and manufacturing facility, which will include 61 manufacturing and production systems, including several OLED evaporation systems. The R&D facility will conduct over 66 planed projects, focusing on technologies such as flexible OLED encapsulation, cost-cutting methods, next-generation displays and more.

OLEDON developed a vertical-plane source deposition technology suitable for ultra-large substrates

Korea-based OLEDON announced that it has developed a vertical-plane source deposition technology that can be used to produce both small-area and large-area OLED panels. The company is now adapting this technology for ultra-large substrates - up to 12-Gen (3300x4000 mm) in size.

OLEDON says that currently-used inline evaporation processes lower the yields for large-area production due to FMM sagging and difficult control of the multiple sources. The company's vertical plane source deposition may prove to be a viable alternative.

IHS: the AMOLED FMM market will reach $1.2 billion in sales in 2021

Analysts from IHS say that as AMOLED displays continue to replace LCD displays and the AMOLED market is growing quickly - the market for fine metal mask (FMM) components will also experience fast growth in coming years.

AMOLED FMM revenue forecast (2017-2022, IHS)

IHS sees the FMM market in 2017 generate $234 in revenues. The market will grow at a compound annual growth rate (CAGR) of 38% until 2022 - to reach $1.2 billion. IHS says that FMM production is a challenge and FMM technology has become a bottleneck as display resolution is increasing and the number of FMM suppliers is limited. The leading producer is Dai Nippon Printing, and the company's FMM masks are using to produce the majority of AMOLED displays.

UDC accelerates its OVJP R&D, shows how the process works

Universal Display recently announced that it is accelerating OVJP R&D, and the company is looking to commercialize this technology with partners. UDC expects it to take a few years before OVJP can really be deployed in production. The company published the video below that shows off the technology and explains the basic principles and advantages.

OVJP stands for Organic Vapor Jet Printing, and the basic idea is to use a gas-stream based process that resembles ink-jet printing but one that uses evaporation OLED materials which outperform soluble ones. In an OVJP process, the OLED materials are evaporated into a carrier gas that delivers them to a jet engine for direct printing of patterned OLED layers. OVJP is intended for large-area OLED displays and can be scaled up to 10-Gen substrates according to UDC.

OLEDON developed a 0.38um shadow mask technology that enables 2,250 PPI

OLEDON announced that it has developed a plane-source evaporation shadow mask process that can achieve a shadow distance of 0.38um - which can enable OLED display resolution to reach 2,250 PPI. The company says it technology will be able to achieve 3,300 PPI in the future.

OLEDON is not alone in the development of plane-source evaporation technology. In November 2016 Sunic Systems announced that it developed a similar AMOLED production process - that can also achieve 2,250 PPI. It may be that Sunic and OLEDON are collaborating on this, it is not clear.

Merck - printed red, green and blue OLED efficiencies are now comparable to vapor-processed ones

Merck is going to discuss its latest soluble OLED material performance at SID DisplayWeek 2017 next month. Merck will detail the printed device efficiencies, voltages, and colors.

According to Merck, the efficiencies of its soluble OLED emitters are now comparable to state-of-the-art vapor-processed devices. Merck will also suggest a move from an evaporated blue common layer device architecture to a printed blue.
