WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.

WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD. demonstrates a strong, albeit fluctuating, commitment to display technologies, with Organic Electronics (OLED) comprising a dominant 47.1% of its portfolio and experiencing a significant surge in 2024 with a +354.5% YoY growth, before a sharp decline in 2025 and so far in 2026. Surprisingly, despite its focus on display, the company has almost entirely shifted away from Integrated Circuit Layout & Arrangement, showing a -100.0% YoY decline in 2026, and Specialty Semiconductor Devices (Legacy), which saw a -100.0% YoY decline in 2024 and no patents since.
