FlexOS - Industrially scaling a novel material and process technology for fully flexible and printable organic electronics

基于柔性印刷电子的塑料显示器预计将彻底改变新型设备的性能、产品差异化和成本。虽然现有的刚性屏幕可以从重量，厚度，坚固性，功耗和使用寿命的阶跃变化中受益，但可以反复弯曲，折叠或卷曲的显示器将成为可穿戴设备等应用中的关键组件。然而，尽管现有的前端技术（如OLED）显示出动态柔性显示器（DFD）所需的灵活性和长期性能，但驱动显示器输出的相应全柔性背板技术尚未实现。NeuDrive Limited开发了一种基于FlexOS（已注册商标）的新型OTFT形状因子和制造工艺，FlexOS是一种基于可溶性小分子/高介电常数半导体粘合剂的专有OSC配方，具有世界领先的移动性，稳定性和均匀性，适用于柔性显示背板。然而，目前的中试工艺与OEM生产线设备/材料不完全兼容，因此neudrive寻求实现一种工业工艺技术，以实现FlexOS-OTFT的经济制造，为DFD背板提供强大的供应链。该项目旨在开发新的工艺技术和专有的被动材料，以支持OEM生产线的立即采用。

Plastic displays based on flexible printed electronics are predicted to revolutionise theperformance, product differentiation and cost of novel device form factors. Whilst existingrigid screens can benefit from a step change in weight, thickness, ruggedness, power use anduseable lifetime, displays that can be repeatedly bent, folded or rolled will be criticalcomponents in applications such as wearable devices. However, despite established frontplanetechnologies such as OLED showing the required flexibility and long-term performance fordynamically flexible displays (DFD), a corresponding fully flexible backplane technology todrive the display output is yet to be realised.NeuDrive Limited have developed a novel OTFT form factor and fabrication process basedon FlexOS (trademarked) - a proprietary OSC formulation based on soluble smallmolecules/high permittivity semiconductor binders - with world-leading mobility, stability anduniformity performance validated for flexible display backplanes. However, the current pilotscaleprocess is not fully compatible with OEM production line equipment/materials andNeuDrive therefore seek to realise an enabling industrial process technology for economicmanufacture of FlexOS-OTFT, underpinning a robust supply chain for DFD backplanes. Theproject aims to develop new process technology and proprietary passive materials to supportimmediate adoption on OEM production lines.
