This project proves the concept of high production rate processes for the fabrication ofsolution processed OLEDs (or other organic electronics) using a patented UV curing process.Polar OLED has proven the benefits of UV cross-linkable materials for organic electronics, inparticular for OLED. Once cross-linked they become insoluble, allowing additional layers tobe deposited on top without contamination. This allows significant performance gains to bemade, while the low-temperature process supports use on most flexible substrates. Thecombination of enabling multiple layers and a low temperature process will be invaluable asthe nascent OLED and flexible display industries develop.While UV curing is used extensively in other industries, there is currently no adoption of itwithin the OLED industry. No process currently exists which could migrate these materialsfrom the lab to the production (or even pre-production) environment. This lack of processexistence proof is slowing the adoption of these materials.This project will prove the concepts of a high volume manufacturing process using UVcuring. The project will address the application of multiple layers, encapsulation andbenchmarking against conventional devices. While the development focus is on curing, amulti-disciplinary effort is required to optimise process and materials/inks together to deliverhigh manufacturing rates.This project proves the concepts of a production process capable of being scaled to highvolumemanufacturing. The program includes development work on new inks, assessment ofthe options for UV curing (and iterating lessons learned back into the ink formulation efforts),and working with potential equipment suppliers and partners (including CPI, the Centre forProcess Innovation, which will be the host for the project – placing the project at the heart ofthe UK’s Plastic Electronics industry.

该项目证明了使用获得专利的 UV 固化工艺制造溶液加工 OLED（或其他有机电子产品）的高生产率工艺概念。Polar OLED 已经证明了 UV 可交联材料对于有机电子产品（尤其是 OLED）的优势。一旦交联，它们就会变得不溶，从而可以在顶部沉积额外的层而不会受到污染，从而显着提高性能，同时低温工艺支持在大多数柔性基材上的组合。随着新兴 OLED 和柔性显示器行业的发展，实现多层和低温工艺将具有无价的价值。虽然 UV 固化已用于其他行业，但目前在 OLED 行业中尚未采用，目前主要不存在可以迁移这些的工艺。材料从实验室到生产（甚至预生产）环境的过程存在证明的缺乏正在减缓这些材料的采用。该项目将证明使用紫外线固化的大批量制造过程的概念。多层，虽然开发重点是固化，但需要多学科的努力来共同优化工艺和材料/油墨，以实现高制造率。该项目证明了能够扩展到大批量制造的生产工艺的概念。计划包括新油墨的开发工作、UV 固化选项的评估（以及将经验教训迭代回油墨配方工作）以及与潜在的设备供应商和合作伙伴（包括 CPI、该中心）合作。 forProcess Innovation 将成为该项目的主办方，将该项目置于英国塑料电子行业的核心位置。
