Company profile

Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd. is a Chinese manufacturer in the semiconductor display industry, founded on May 20, 2014, and headquartered in Wuhan, Hubei, China. The company operates as a subsidiary of TCL Technology Group Corp., falling under the umbrella of TCL China Star Optoelectronics Technology (TCL CSOT), a global leader in display technology. It employs more than 1,000 people.

The company's operations include the manufacturing of mobile phone TFT-LCD panels. As part of TCL CSOT, its broader activities encompass the development and production of next-generation display technologies such as Mini LED, Micro LED, OLED, and inkjet-printed OLED. Its product portfolio extends to large area displays, small-to-medium-sized displays, touch modules, interactive whiteboards, video walls, automotive displays, and gaming monitors. The company holds certifications for the manufacturing of Liquid Crystal Displays and Modules.

In terms of patent litigation, Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd. is primarily observed as a defendant. Our tracking database shows one instance where the company was named as a defendant: Bishop Display Tech LLC v. TCL Electronics Holdings Ltd. et al., filed on March 27, 2026, in the U.S. District Court for the Eastern District of Texas. This venue is known for its plaintiff-friendly patent litigation environment. In this case, the company was sued alongside its parent entity, TCL Electronics Holdings Ltd., and other affiliates, suggesting an assertion against the broader TCL display manufacturing ecosystem.

While our database tracks the company as a defendant, public reports indicate that Wuhan China Star Optoelectronics Semiconductor Display Technology, as a TCL subsidiary, has also initiated patent infringement lawsuits. For example, the company filed a suit against Samsung, Walmart, and Best Buy in the Eastern District of Texas, alleging infringement of its OLED patents in devices such as laptops, wearables, and Google Pixel phones. This demonstrates an active and two-way litigation posture within the broader TCL CSOT group.
