This PFI: AIR Technology Translation project focuses on translating a flexible transparent conductor material to be used as a low-cost transparent electrode for the fabrication of organic light emitting diodes for flat panel display and lighting applications. The project will result in a prototype substrate, on which organic light emitting diodes will be demonstrated with high light emission efficiency and simplified device structure. This substrate has the following unique features: high surface conductivity, low surface roughness, and mechanical flexibility; this is a combination of properties that no existing material can provide. These features provide the important advantages of lower cost and higher light emission efficiency when compared to the leading competing transparent electrode in this market space. The integrated substrate is important because the commonly used flexible transparent electrode technology cannot meet the performance requirements for future flexible displays that would be required for wearable electronics, an area which is gaining increasing attraction.The project engages Polyradiant Corp. to optimize the processing of the integrated substrate for scalability study, transition onto roll-to-roll pilot production line, and guide commercialization aspects in this technology translation effort from research discovery toward commercial reality.This project addresses the following technology gap(s) as it translates from research discovery toward commercial application. The surface conductivity, surface smoothness, and visual transparency of the integrated substrate will be optimized via processing conditions and polymer formulation. The light extraction efficiency of organic light emitting diodes based on the integrated substrate will be enhanced by at least 100% by adding nanoparticles into the substrate. A solution-based process will be developed to fabricate prototype integrated substrate and validate the prototype for high-efficiency flexible light emitting diodes. The new substrate will pave the way to low-cost, high-efficiency, and flexible organic light emitting diodes. The potential economic impact is expected to be hundreds of million dollars in the next five years, which will contribute to the U.S. competitiveness in organic light emitting diode based displays and lighting panels with a present market size of ~$4B and growing rapidly.

此PFI：空气技术翻译项目着重于翻译柔性透明导体材料，用于用于制造有机光散发二极管的低成本透明电极，用于平板显示和照明应用。该项目将导致原型底物，以高光发射效率和简化的设备结构来证明有机光发射二极管。该基材具有以下独特的特征：高表面电导率，低表面粗糙度和机械柔韧性；这是现有材料无法提供的属性的组合。与该市场领域的领先竞争透明电极相比，这些功能提供了较低成本和较高的发光效率的重要优势。 集成的衬底很重要，因为常用的柔性透明电极技术无法满足可穿戴电子设备所需的未来灵活显示的性能要求，这一领域正在增加吸引力的增加。该项目与PolyRyAdiant Corp.相关。要优化综合基质性研究的综合底物处理，从而从滚动到滚动的生产线程进行了转换，从而从滚动滚动的产品进行了转换，从而从滚动飞行器进行了转换。解决以下技术差距，因为它从研究发现转化为商业应用。集成底物的表面电导率，表面平滑度和视觉透明度将通过处理条件和聚合物公式进行优化。通过将纳米颗粒添加到底物中，至少100％将提高基于综合底物的有机光二极管的光提取效率。将开发基于溶液的过程来制造原型集成的基材，并验证原型的高效柔性发光二极管。新的底物将为低成本，高效率和柔性有机光二极管铺平道路。预计在未来五年内，潜在的经济影响预计将是数亿美元，这将有助于美国在有机光发射二极管的显示和照明面板中的竞争力，目前的市场规模约为4B美元，并且增长迅速。
