EO (亿欧) reported on July 2,Chenxian Optoelectronics (辰显光电) recently announced the completion of a B-round financing of several hundred million RMB. This round was led by the Sichuan Advanced Manufacturing Investment Guidance Fund managed by CICC Capital, with participation from CCB Investment, Ceyuan Capital, Chengdu Sci-tech Investment, Gaoxin Beite, Wise Road Capital, Eastern Fortune Capital, and Jiaozi Capital..
The funds raised in this round will be mainly used for the construction and capacity expansion of the TFT-based Micro-LED mass production line, further consolidating its leading position in the Micro-LED display field.
Chenxian Optoelectronics (辰显光电) was established in 2020 and isThe first high-tech enterprise in the mainland dedicated to the independent R&D, mass production, and market sales of TFT-based Micro-LED, jointly established by state-owned capital institutions such as Chengdu High-tech Investment Group and Sichuan Integrated Circuit and Information Security Industry Investment Fund, and industrial capital such as Visionox (维信诺).
In terms of technology, Chenxian Optoelectronics (辰显光电) has successively overcome four major industrialization bottlenecks: mass transfer, driver architecture, seamless splicing, and mixed Bin technology—with a mass transfer efficiency of 10 million chips/hour, a yield rate of 99.995%, and 100% lighting after repair. As of April 2026, the total number of patent applications exceeded 1,200, with invention patents accounting for over 96%, and 594 patents have been granted.
Micro-LED is regarded as the next-generation display technology following LCD and OLED. It outperforms existing solutions in dimensions such as high brightness, contrast, lifespan, and power consumption, and is suitable for scenarios like large-size commercial displays, transparent displays, vehicle-mounted displays, and high-end home theaters. Industry data shows that in 2024, the market size of Micro-LED display modules in China was approximately 2.85 billion yuan, a year-on-year increase of 86%.
It is worth noting that industrialization has long been constrained by bottlenecks such as mass transfer yield, driver adaptation, and splicing consistency, so mass production progress has lagged behind market expectations.
Chenxian Optoelectronics (辰显光电) focuses on the TFT-based route. Compared to PCB-based solutions, TFT substrates support AM active driving and independent single-pixel control, making them more suitable for the large-scale manufacturing of large-sized products. By the end of 2024, Chenxian Optoelectronics (辰显光电) lit up the first TFT-based Micro-LED mass production line in mainland China, and will take the lead in mass production shipments in 2025. It is currently the only Micro-LED enterprise to have completed full-process coverage from R&D to mass production.
Currently, the competition in the Micro-LED sector is intense.BOE (京东方), TCL CSOT (TCL华星), AUO (友达), Innolux (群创), Visionox (维信诺), Tianma (深天马)...and others all have relevant layouts. However, most enterprises are still in the pilot or sample stage, and mass production lines have not yet been built.
The core competitiveness of Chenxian Optoelectronics (辰显光电) lies in prioritizing mass production,The first mass production line has been lit up and shipped, and the four core technologies are self-developed and verified through the production line.. Meanwhile, as the governing unit of the China Micro-LED Strategic Alliance, Chenxian Optoelectronics (辰显光电) is promoting upstream and downstream collaboration to build an industrial closed loop of "materials—panels—terminals".
In terms of commercialization, Chenxian Optoelectronics (辰显光电) has launched multiple world-first products: 270-inch 8K, 135-inch P0.7 tiled screen, 88-inch P0.5 tiled screen, P0.5 transparent tiled screen, and light field naked-eye 3D screen, covering high-end scenarios such as large-size commercial display, transparent display, and immersive experience. It has also successively signed strategic cooperation agreements with Junyi Digital (君逸数码), TPV Technology (冠捷科技), Leyard Optoelectronic (雷曼光电), and Xinyichang (新益昌), covering sectors such as smart city, display terminals, LED packaging, and core equipment.
In addition, the world's first Micro-LED international array standard, led and initiated by Chenxian Optoelectronics (辰显光电), has been officially established. The LED creative screen project at Kunshan Xiajiahe Park verified its capability to deliver customized solutions.
Previously,Chenxian Optoelectronics (辰显光电) has previously completed its Angel Round and Series A financing., investors include institutions such as Ceyuan Ventures (策源资本), Tianfu Xinyun Fund (天府芯云基金), Chengdu Gao tou Electronics Group (成都高投电子集团), Sichuan Manufacturing Collaborative Development Fund (四川制造业协同发展基金), Chengdu High-tech Future Science and Technology City (成都高新未来科技城), Hefei Beichengxin Venture Capital (合肥北城信创投), and Huaxi Jinzhi (华西金智). The completion of this Series B financing also marks that Vitrox (辰显光电) continues to gain recognition from the capital market.
