Kateeva was established in 2008 at MIT with an aim to pioneer OLED ink-jet deposition processes.
The company developed innovative inkjet printing equipment, branded as YIELDJet printers. Kateeva started to offer ink-jet based encapsulation systems in 2014, used to protect flexible OLED panels. Kateeva's encapsulation performance is excellent and it was already reported that these systems are used in flexible OLED mass production - and Kateeva claims that it takes a "commanding lead" in the OLED organic thin-film encapsulation (TEF) market.
In 2017 Kateeva formally introduced its inkjet equipment for large-area RGB OLED emitter deposition. Kateeva brands its new line as YIELDJet Explore and these systems are currently targeted for R&D lines and pilot lines.
Kateeva is also developing printers that can deposit quantum dot materials, and according to reports the company's equipment will be used by Samsung to deposit QDs for its QD-OLED TVs.
The latest Kateeva news:
Kateeva did not yet receive any QD-OLED inkjet printers orders from SDC, and may lose its patent portfolio to its latest investor
In January 2022 it was reported that Samsung has decided to change course, and rely on Kateeva's inkjet printers in its 2nd QD-OLED production line, as the Semes printers do not perform as well as Samsung hoped.
In 2020 Samsung decided to use inkjet printers made by Korea's Semes, in its QD-OLED production lines. This created a major problem for Kateeva which hoped to win that account, which resulted in massive layoffs including some of its executives. These inkjet printers are used to deposit the QD layer in Samsung's QD-OLED panels.
According to new reports from Korea, Samsung has decided to change course, and rely on Kateeva's inkjet printers in its 2nd QD-OLED production line (the SDC 98.5-Gen Q-2). The reports suggests that the Semes printers do not perform as well as Samsung hopes, and these also cost more than Kateeva's printers (but Semes is affiliated with Samsung, which helped it to get the orders).
OLED inkjet printing developer Kateeva announced that it has established a strategic partnership with high-index material maker Pixelligent Technologies. The collaboration aims to optimize the light output efficiency by inkjet-printing of planarization layers over microlens arrays.
Collaboration Aims to Optimize Light Output Efficiency in Mobile Phones with Inkjet-Printed Planarization Layer over Microlens Arrays. To increase the efficiency, the companies suggest using a patterned structure followed by an inkjet-printed high-refractive index filling and planarization layer which enables more light from the OLED layer below to reach the top surface.
US-based OLED inkjet printing developer Kateeva announced that Tianma has ordered an R&D 200mm YIELDJet Explore printing system to expand its OLED research and development programs.
Kateeva reveals that Tianma is already using its TFE system in its OLED mass production fabs. Kateeva also says that this tool will be the 60th Kateeva printer at customer sites.
US-based OLED inkjet printing developer Kateeva announced a massive layoff plan - the company will slash its staff by 144 employees, including a number of executives - its president, CMO and COO.
This is sad news - and surprising as well as Kateeva seems to be on the forefront of OLED inkjet printing. Kateeve raised over $125 million (including $88 million in 2016) and is working with Samsung, BOE, LG, Johua Printing and other companies. The company is leading with ink-jet printing of OLED encapsulation materials and was set to supply Samsung with the QD printing equipment for SDC's upcoming QD-OLED TV line.
According to a report from Korea, LG Display has halted production at one of its production lines at its E6 production fab, LG's 6-Gen flexible OLED line that commenced production at the end of 2018.
According to the report, the problem lies with LGD's thin film encapsulation equipment - specifically the equipment that deposited the organic particles - which apparently suffers from sub par performance, not good enough for commercial production. LG is using equipment made by its subsidiary LG PRI in the E6-1 line, which is now halted.
Guangdong Juhua Printing Display Technology was established in 2016 by CSOT and Tianma with an aim to develop OLED ink-jet printing technologies and enable companies in China to collaborate on this technology.
While TCL-owned CSOT already announced that it is collaborating with Kateeva (and others), it was not clear whether Juhua Printing Display was also using Kateeva's printers, but we now have confirmation that indeed the China-based consortium is based on Kateeva's printers. This is obviously a major win for Kateeva, who is also working with BOE and Samsung, among others.
Samsung progresses with its inkjet printing OLED technology, to apply it to next-generation monitors and laptops
According to ETNews, Samsung Display has made significant progress with its OLED ink-jet printing process technology, and the company now aims to apply this technology to produce medium-sized panels for OLED laptops and OLED monitors. Samsung may also use this process to produce smaller tablet displays.
It seems that Samsung is aiming to settle on three main next-generation OLED technologies - evaporation (FMM) OLEDs for small-sized display, ink-jet OLED deposition for medium-sized panels and hybrid QD-OLEDs for large-area OLED TV panels. It's other display technologies are QD-LEDs for TVs and Micro-LEDs for next-generation small and large area displays.
Samsung Display is developing hybrid QD-OLED TV technology, and according to estimates, the company aims to begin trial production in 2019. It is also estimated that Samsung has several challenges to overcome, but according to new reports from Digitimes, Samsung is aiming to start installing equipment for the new fab as early as December 2018.
The new fab will begin operation in the second half of 2019 - pilot production at first which will be expanded to full scale mass production. The new fab will be built in Samsung's L8 LCD production line in Asan, and will take over one of the two lines currently in operation at the fab. Samsung's initial production capacity will be around 25,000 monthly G8 substrates.
In February 2018 it was first reported that Samsung Display is developing TV panels based on hybrid quantum-dots and OLED architecture (QD-OLED). Samsung later confirmed it is developing such technology, but with no immediate plans to commercialize it.
ETNews now reports that Samsung is now working to establish a pilot 8-Gen line for QD-OLED production. ETNews says that Samsung is collaborating with both Canon Tokki and Kateeva to develop the production equipment - apparently the OLED layers will be evaporated using Canon's machines while the QD filters will be deposited using ink-jet printing equipment made by Kateeva. Samsung aims to finalize the production line by the second half of 2019.
