Taiwanese display manufacturer Radiant Opto-Electronics agreed to buy Finnish optical materials specialist Inkron Oy from Japan’s Nagase Group for ¥1.035 billion ($7.1 million), marking its third European acquisition in two years.
The deal, announced Tuesday and expected to close in mid-August pending regulatory approvals, continues Radiant’s aggressive expansion into advanced optical manufacturing. The Kaohsiung-based company previously acquired Denmark’s NIL Technology and Finland’s Nanocomp as part of what it calls a “dual-engine” transformation strategy launched in 2023.
Inkron, founded in 2013, develops siloxane-based resins and optical coatings with refractive indexes spanning 1.1 to 2.0 for nanoimprint lithography processes. The company’s materials target applications including augmented reality waveguides, LIDAR components and diffractive optical elements.
Nagase Group acquired a stake in Inkron in 2016 and has been manufacturing the Finnish company’s products at its Japan facility. The Japanese chemicals giant has been collaborating with Inkron on OLED display materials since that partnership began.
For Radiant, the acquisition represents another step toward vertical integration in optical component manufacturing. The company generated $1.63 billion in trailing 12-month revenue as of March 2025, primarily from backlight modules for LCD panels used in consumer electronics.
The transaction underscores Taiwan’s semiconductor and display manufacturers’ push to move up the value chain into higher-margin specialized components as traditional LCD markets mature.
