Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd. (Chinese: 武汉华星光电半导体显示技术有限公司) is a display-panel manufacturer headquartered at No. 8 Zuoling Avenue, Optics Valley Smart Industrial Park, East Lake High-Tech Development Zone, Wuhan, Hubei. It was registered on 24 October 2016 with registered capital of RMB 21 billion and is majority-owned by TCL China Star Optoelectronics Technology (TCL CSOT), the display arm of Shenzhen-listed TCL Technology Group (SZSE: 000100). Minority holders have included Hubei provincial funds, Wuhan Optical Valley Industrial Investment and a Wuhan semiconductor-display fund; TCL CSOT has bought in minority stakes over time (e.g. a 5.24% interest acquired in 2025). Chinese corporate-registry data (Qichacha) lists 5,000–5,999 insured employees; no standalone revenue is disclosed.
Operations. The company runs TCL CSOT's Gen-6 flexible LTPS-AMOLED fab (t4) in Wuhan — a line with reported project investment of roughly RMB 38 billion, started in 2017, producing small- and medium-sized flexible and foldable AMOLED panels and modules for smartphones, wearables, tablets and automotive displays. Its patent filings (roughly 5,400 records) cover display panels, display modules, foldable/hinge structures, array substrates, gate-drive circuits and flexible circuit boards. It is a practicing manufacturer, not an NPE.
Litigation posture. The single tracked matter shows it as plaintiff/petitioner and none as defendant. That "plaintiff" role is a PTAB inter partes review, not a district-court assertion suit: Wuhan China Star joined Mianyang BOE Optoelectronics, Tianma Microelectronics and Visionox as co-petitioners against Samsung Display's OLED patents — a coordinated defensive campaign by Chinese panel makers following Samsung Display's US infringement actions against BOE (E.D. Texas, June 2023, and an ITC Section 337 complaint). No cases against this entity cluster in plaintiff-friendly venues.
Notable matters. In IPR2023-00941 (US 7,414,599) the Board found no challenged claim unpatentable (December 2024); in IPR2024-00620 (US 9,330,593) claims 1, 2 and 15–18 were held unpatentable (September 2025). Petitioners including Wuhan China Star appealed to the Federal Circuit (No. 26-1092), with briefing in 2026.
