Company patents
Hefei BOE Optoelectronics Technology Co., Ltd.
Hefei BOE Optoelectronics Technology Co., Ltd. demonstrates a strong, albeit fluctuating, commitment to display technologies, with Liquid Crystal & Optical Modulators comprising 59.0% of its portfolio and showing significant growth in 2024 (+61.5% YoY) and 2025 (+28.6% YoY), despite a sharp decline so far in 2026 (-70.4% YoY). Surprisingly, while Display Drivers saw a 100.0% YoY increase in 2025, the company's focus on Organic Electronics (OLED) appears to be a shifting priority, with a consistent decline in patenting activity since 2023, including a -50.0% YoY drop in 2025 and another -50.0% so far in 2026.
