JOLED Sues Samsung Over OLED Patents

JOLED announced that it has filed lawsuits in the US and Germany against Samsung Electronics and Samsung Display. JOLED says that Samsung infringed on its OLED patents without a license.

JOLED (Japan OLED) was established in August 2014 by Japan Display, Sony and Panasonic to produce OLED displays using inkjet printing technology. The company has (or applied for) around 4,000 global OLED patents. We do know which patents JOLED refers to in its new law suit.

JOLED recently announced that TCL/CSoT has invested around $187 million USD in the company, and has also signed an agreement to jointly develop OLED TV printing technologies. This is the last investment reported recently as JOLED is accelerating its OLED mass production plans.

In December 2017 JOLED started commercial low-volume production of its 21.6″ 4K OLED panels, at the company’s pilot 4.5-Gen line, and in November 2019 the company announced that it has started sampling inkjet-printed OLED display panels in its 5.5-Gen (1300×1500 mm) production line in Nomi, Ishikawa Prefecture, Japan. Mass production at the Nomi fab is planned for later in 2020.

In August 2018 JOLED raised around $400 million from four new investors – auto parts maker Denso ($270 million), major trading house Toyota Tsusho ($90 million) and Sumitomo Chemical and Screen Holdings. Later in August, JOLED announced that it has signed an agreement to develop, manufacture, and sell printing equipment together with Panasonic and Screen Finetech. In April 2019 JOLED announced that it has raised around $228 million from INCJ, Sony and Nissha to build post-processing module production lines at its Mobara, Chiba prefecture, plant.
