Kateeva starts to ship 8K QD deposition systems to Samsung Display

According to reports, Kateeva started to ship quantum dots inkjet printing equipment to Samsung Display, for the production of QD-OLED panels. It appears as if Samsung is interested in producing 8K QD-OLEDs, and its current inkjet printing supplier, Semes, is not ready with printers that support 8K QD deposition.

Kateeva announced that it has designed a new system, called the YIELDjet Jarvis, that supports 8.5-Gen substrates and can indeed enable 8K TV deposition. Kateeva says that the Jarvis system has the ability to print using solvent-based RGB inks or nanoparticle inks with its proprietary ink recirculation system to ensure uniform particle distribution.

Is printed-OLED producer JOLED on the brink of bankruptcy?

JOLED (Japan OLED) was established in August 2014 by Japan Display, Sony and Panasonic with an aim to become an OLED medium display producer. Following years of R&D and initial production, the company initiated mass production of its OLEDIO panels in 2021 at its new 5.5-Gen production line in Nomi, Ishikawa Prefecture, Japan.

JOLED's panels appeared on the market, but only for high-end applications such as LG's professional monitor range. According to a new report from Korea, the company did not manage to find a new investor and is now on the verge of bankruptcy.

AP Systems developed an inkjet printing system for OLED OCR deposition

Korea-based OLED equipment maker AP Systems (APS) announced that it developed a new system to deposit optically transparent resin (OCR) using an inkjet printing process.

Current OLED production uses an adhesive tape (OCA) to connect the cover glass to the display. But OCA is time-consuming and relatively expensive. OCR, on the other hand, is deposited directly on the panel and is more cost effective. We recently reported that Samsung Display aims to adopt OCR technology in its foldable OLEDs to reduce costs, and is testing inkjet systems made by STI.

Kateeva did not yet receive any QD-OLED inkjet printers orders from SDC, and may lose its patent portfolio to its latest investor

In 2020 Kateeva lost Samsung's QD-OLED inkjet printing inkjet printing contact to Korea's Semes, which resulted in massive layoffs including some of Kateeva's executives.

Notion Systems sells several n.jet EHD system

Notion Systems GmbH, a leading manufacturer of inkjet printing systems for functional materials, has received several orders for its newly developed n.jet EHD platform. The EHD (Electrohydrodynamic) technology is a promising technology to reduce structure sizes to less than one micron and enables the use of higher viscosity inks. It supports printing of small structures in microelectronics, semiconductor and next generation display manufacturing. Notion will ship the first four n.jet EHD systems to undisclosed customers in Europe in the third quarter of 2022.

The overall benefits of inkjet printing in the display industry are:

  • Printing of smaller features sizes compared with conventional inkjet printing
  • Elimination and replacement of various process steps
  • Material savings, as printing is done digitally and without masks
  • Replacement of expensive process steps

Notion Systems n.jet EHD system and display

Several presentations and discussions with industry representatives during Display Week 2022 in San Jose USA revealed that inkjet printing technology for OLED/QLED displays will play an important role in future production. Since standard inkjet printing has a limitation at 400 dpi, EHD technology is the way to go. This was one of the main reasons why Notion entered into a cooperation with EHD printhead manufacturer Scrona in Switzerland last year, says Antonio Schmidt - SVP Sales & Marketing of Notions Systems
