Samsung Display Complaint Accuses Joled, Asus of Infringing OLED Patent

January 12, 2021 by Paul Gluckman|Intellectual Property

Asus ProArt PQ22UC 4K monitors bearing OLED panels sourced from Joled in Japan infringe Samsung Display’s September 2017 U.S. patent (9,768,240) on thin-film transistor array substrates for OLED screens, alleged a complaint (in Pacer) that the Korean panel maker filed Friday in U.S. District Court in Waco, Texas. Joled is a panel maker and R&D company forged from an expired Panasonic-Sony joint venture agreement and resurrected six years ago with public and private sector partners, including minority owners Panasonic and Sony (see 1408010054). It specializes in small runs of medium-sized OLED substrates, but its production volumes in the display panel supply chain are "tiny," emailed Display Supply Chain Consultants CEO Ross Young Friday. Samsung Display seeks a permanent injunction barring Asus and Joled from future infringement, plus punitive and compensatory damages. The defendants didn't respond to requests for comment.
