Company patents
WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.
WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD. has a clear focus on display technologies, with Organic Electronics (OLED) making up a dominant 46.7% of its portfolio, despite a notable decline in patenting activity in this area by -53.3% in 2025 and -62.9% so far in 2026. While most categories saw significant growth in 2024, such as Multi-Chip & 3D Assemblies with a +1400.0% YoY increase, the company appears to be shifting its priorities, as evidenced by a dramatic -100.0% YoY decline in Integrated Circuit Layout & Arrangement patents in 2026 and a complete cessation of patenting in Specialty Semiconductor Devices (Legacy) since 2024.
