Company patents
TCL Technology Group Corporation
TCL Technology Group Corporation's patent strategy reveals a strong, sustained focus on Organic Electronics (OLED), which constitutes 79.2% of its portfolio, despite a significant decline so far in 2026 (YoY -69.0%). Surprisingly, while heavily invested in display technologies, the company has almost entirely abandoned legacy areas like Specialty Semiconductor Devices (Legacy) and LED & Optoelectronics (Legacy CPC), both showing 100% year-over-year declines in 2024 and 2025 respectively, indicating a clear shift towards advanced display materials.
