在溶液处理OLED显示器的应用中，将溶剂喷墨打印到绝缘聚合物层上，以原位构建微凹槽作为银行结构。喷墨蚀刻工艺不仅消除了光刻的阴影和曝光，而且能够在任何功能层上构建银行结构。CYtop聚合物与有机层之间的正交溶解度避免了任何溶剂侵蚀。在喷墨蚀刻的CYtop微槽上喷墨打印出一种蓝色发光聚合物，成功地制造出像素化显示器，像素分辨率为每英寸140线。根据需要在任何层上原地形成银行结构，为设计新的面板结构，器件架构和沉积方法提供了更多的选择。
Inkjet-printing a solvent onto an insulating polymer layer is employed to in situ build microgrooves as bank structures in the application of a solution-processed OLED display. The inkjet-etching process not only eliminates photolithography's shadow mask and photo exposure, but is also capable of constructing bank structures on any functional layer. The orthogonal solubility between the CYtop polymer and the organic layer avoids any solvent erosion. A pixelated display is successfully fabricated by inkjet-printing a blue-emitting polymer onto inkjet-etched CYtop microgrooves with a pixel resolution of 140 lines per inch. Forming a bank structure in situ on any layer as needed offers more choices to design a new panel structure, device architecture, and deposition methods.
