CSoT details its OLED ink-jet printing plans, collaborates with Kateeva, Sumitomo, Merck, DuPont and Tianma

Last month CSoT (TCL) announced plans to establish a 11-Gen LCD+OLED TV fab in Shenzhen, China. Details on the OLED part of that fab were not given, but now we have some updates following the company's investor day.

The new fab will use Oxide-TFT backplanes, and it turns out that the OLED part of the fab will also use the 11-Gen substrates (which may be cut for the actual OLED front plane deposition). Out of the entire capacity of 90,000 monthly substrates, the OLED line will use 20,000 substrates. The fab will start mass production in 2021.

OLED Ink-jet printing market situation, early 2018

Many OLED producers believe that Ink-Jet printing of OLED emissive materials is the best way to achieve lower-cost OLED TV production, and to enable OLEDs to compete in the medium part of the TV market. Ink-Jet printing is an efficient process (less material waste compared to evaporation) and it can be very quick as well. The main drawbacks of inkjet are the limited resolution and the need for soluble emissive materials which are less efficient compared to evaporation ones.

These challenges are being overcome, and it seems that at least four groups (in Korea, Japan and China) are charging forward towards mass production of ink-jet printed OLEDs. Ink-jet printer makers and soluble material suppliers are also optimistic ink-jet printing commercialization will soon be here as the material performance gap is diminishing.

JOLED starts commercial shipments of its printed 21.6" 4K OLED monitor panels

In June 2017 JOLED announced that it started to sample 21.6" 4K OLED panels, with plans to initiate low volume production at its 4.5-Gen pilot inkjet production line. JOLED announced today that it has began commercial shipments of these panels. We do not know JOLED's first customer but it is likely to be Sony.

JOLED says that it has now achieved the necessary product quality and production yields. The product was already selected for use in medical monitors (again, we believe this is Sony, who we know received JOLED's first samples and already has its own 25" OLED medical monitor that uses Sony's own OLEDs). JOLED also aims to ship these panes to other OLED monitors applications.
