As the original holder of the PSE Technology display technology patent series, LEDMAN initiated its global patent strategy five years ago. To date, the company has secured invention patent grants in countries including Japan, Australia, Canada, and Germany, with authorizations in other regions actively progressing.
In 2020, LEDMAN pioneered the release of Micro LED Pixel Engine Technology (PSE Technology), which achieves groundbreaking innovation in pixel arrangement and AI algorithms. This technology resolves the conflict between cost reduction and resolution enhancement in Micro LED display products and has been widely adopted across multiple LEDMAN COB display products. It has also been honored with the “2021 ISLE Annual Scientific Achievement Award” and the “2025 Japan IDPA International Pioneer Design Award.”
Given the significant application value of LEDMAN’s PSE Technology, certain industry peers have utilized the aforementioned infringing technologies at international exhibitions and customer scenarios. These actions are suspected of violating LEDMAN’s patent rights. Based on its overseas invention patents, LEDMAN is now preparing to initiate international litigation proceedings, demonstrating the company’s determination to resolutely protect its legitimate rights and interests globally. Meanwhile, multiple lawsuits against certain domestic peers are still ongoing in China.
As a leading listed company in China’s LED display industry, LEDMAN has always built its reputation on technological innovation and places strong emphasis on intellectual property protection. With cumulative patents exceeding thousands domestically and internationally, the company’s portfolio covers multiple domains including Micro LED display product structure, packaging, substrates, pixel arrangement, control, and interaction. This continuous effort strengthens LEDMAN’s core competitiveness and fuels its high-quality development.
