October 31 – Radiant Opto-Electronics (6176.TW) today announced the completion of its acquisition of Inkron Oy (Inkron), a Finnish high-end optical materials manufacturer. The share purchase agreement (SPA) was signed on June 25, 2025, establishing the framework for the acquisition. Following approval from Finland’s Ministry of Economic Affairs and Employment (MEAE) in October, the transaction was officially completed on October 31, 2025.
In recent years, Radiant has strategically expanded into comprehensive optical integration services, focusing on next-generation compact image-sensing and display products. With the completion of this acquisition, Radiant not only enhances its manufacturing capabilities but also strengthens its independence in the research and development of critical materials by integrating Inkron’s materials experts, thereby solidifying its foundation in in-house nanoimprint and optical packaging processes.
Materials Innovation Drives Advancements in Optical Processes
Firstly, Inkron’s advanced optical coating products help optimize the light path design of micro-LED and OLED displays. By precisely controlling the refractive index and film thickness, these coatings can significantly improve optical efficiency and reduce reflection losses—minimizing glare, enhancing brightness, and boosting color contrast—to deliver a more uniform and refined visual performance that elevates overall display quality.
Secondly, in the field of optical sensing, Inkron’s resin systems are compatible with processes such as nanoimprint, photolithography, and inkjet printing. These high-performance formulations can be applied to various substrates and support wafer-level processing, enabling precise light manipulation at the nanoscale. This technological advancement allows the integration of eye-tracking, depth-sensing, and temperature-detection functions into increasingly compact and lightweight devices.
Lastly, in the domain of optical waveguides, Inkron’s proprietary high- and low-refractive-index resins support low-temperature and photo-curable processing, enabling the formation of light channels on diverse substrates. This capability plays a key role in advancing Radiant’s development of wearable biosensing devices and paves the way for applications in healthcare, augmented reality (AR), and other emerging fields of human–machine interaction.
Optical Innovation at the Core: Powering human–machine interaction and Mixed Realities
Over the years, Radiant has gradually evolved from traditional backlight module manufacturing processes such as CNC machining and plastic injection to advanced optical fabrication techniques, including nanoimprint and electron-beam lithography. With the addition of Inkron, Radiant is extending its reach into high-end optical materials, further enhancing its optical packaging, adhesive, and coating processes. This acquisition underscores the integration of mass production and materials innovation. By leveraging its comprehensive optical platform, Radiant aims to become a leading optical solutions provider, advancing human–machine interaction technologies and driving innovative applications that seamlessly bridge the physical and virtual worlds.
