Wuhan Tianma Microelectronics Co., Ltd. is a Chinese display manufacturer founded on November 17, 2008, and headquartered in Wuhan's East Lake Hi-tech Development Zone. The company is a joint venture between Tianma Microelectronics Co., Ltd. and Hu Bei Science and Technology Investment Co., Ltd. Its parent, Tianma Microelectronics Co., Ltd., was established in 1983 and is a public company listed on the Shenzhen Stock Exchange (SZ. 000050). Wuhan Tianma is a key manufacturing site for its parent, which has a global presence and serves various technology sectors.
The company operates as a high-tech enterprise specializing in the design, manufacturing, and sale of small- and medium-sized displays. Its product portfolio includes Thin-Film-Transistor Liquid-Crystal Display (TFT-LCD) panels, color filters (CF), and Active-Matrix Organic Light-Emitting Diode (AMOLED) displays. These products are primarily used in high-end smartphones, tablet PCs, smart wearables, and automotive and industrial applications. The Wuhan facility operates both a Gen 4.5 TFT-LCD production line and a Gen 6 AMOLED production line.
As an operating company, Wuhan Tianma Microelectronics has a defensive patent litigation posture in the United States. The company has no record as a plaintiff in the tracked U.S. patent database. It has appeared once as a defendant in a patent infringement lawsuit filed in the U.S. District Court for the Eastern District of Texas, a venue known for patent litigation.
The single tracked case is LG Display Co., Ltd. v. Tianma Microelectronics Co., Ltd. et al., filed in June 2025. This suit involves a dispute between two major display manufacturers, indicating litigation between direct competitors in the global display market rather than an assertion by a non-practicing entity.
