Yeolight

What Yeolight does

Yeolight (Beijing Yeolight Technology Co., Ltd.) is a Chinese deep-tech manufacturer founded in 2015 that develops and produces automotive-grade OLED lighting panels and complete lamp modules. It is one of only three companies globally — alongside LG and Osram — with mass-production capability for automotive OLED lighting, and the only domestic Chinese enterprise with this capability. The company operates through three wholly-owned entities: Beijing Yeolight Technology (headquarters and R&D center in Haidian District), Gu'an Yeolight Technology (the 2.5-Gen OLED lighting production base in Hebei Province, operational since October 2016 with 500M RMB invested and 6,286+ sqm of clean room), and Huaibei Yeolight Technology (the 4.5-Gen industrialization project in Anhui Province with 2 billion RMB total planned investment, which lit up in November 2023 and is designed to become the largest OLED automotive lighting production base globally).

The company's technology portfolio spans five OLED platforms: digital OLED (≥32 independently controllable zones per panel, with production implementations reaching 882 pixels on the Dongfeng Nissan N7), flexible OLED (0.1mm thickness, <5mm curvature radius), transparent OLED (>50% transmittance), white OLED (>70 lm/W with CRI >90), and multi-color OLED spanning the visible spectrum. Its core engineering differentiation is solving automotive qualification — achieving LT70 lifetime exceeding 20,000 hours and operating temperature range of -40°C to 105°C with anti-radiation and anti-vibration reliability — which consumer-grade OLED panels cannot meet. Yeolight holds 471+ granted patents (70%+ invention patents) and is the lead drafter of China's first OLED lighting national standards (GB/T 39075 series).

Yeolight generates revenue primarily through B2B direct sales of OLED panels and lamp modules to automotive OEMs and Tier-1 lamp manufacturers under multi-year vehicle-program contracts — key relationships include exclusive supply of OLED tail lights for the FAW Hongqi H9 (China's first mass-produced OLED tail light vehicle, launched July 2020), supply into Dongfeng Nissan N7 and Dongfeng LANDVO Zhiyin, and co-development partnerships with Xingyu Automotive Lamps, Huayu Visual Technology, Yifeng/Yanfeng, and MAND. Secondary revenue streams include branded consumer OLED products (SEAYEO for photonic beauty/wellness devices; YEOCARE for UV LED sterilization) sold via Chinese e-commerce platforms, and an emerging photomedicine vertical targeting wearable flexible OLED therapeutic devices for 2025 commercialization. The company has closed a C+ financing round (January 2024) with investors including Chuangyuan Venture Capital, Hua Capital, Ruixin Touzi, Summitview Capital, and Wuhan Hongchuang.
