Significant potential of electronic textiles for wearable applications has triggered active studies of luminescent fibers toward smart textile displays. In spite of notable breakthroughs in the lighting fiber technology, a class of information displays with a luminescent fiber network is still underdeveloped due to several formidable challenges such as limited electroluminescence fiber performance, acute vulnerability to chemical and mechanical factors, and lack of decent engineering schemes to form fibers with robust interconnectable pixels for two-dimensional matrix addressing. Here, we present a highly feasible strategy for organic light-emitting diode (OLED) fiber-based textile displays that can overcome these issues by implementing prominent solution options including compatible fabrication method of OLED pixel arrays on adapted fiber configurations and chemically/mechanically sturdy but electrically conductive passivation system. To create solid interconnectable OLED fibers without compromising the high electroluminescence performance, phosphorescence OLED materials are deposited onto process-friendly fibers of rectangular stripes, where periodically patterned OLED pixels are selectively passivated with robust polymer and circumventing metal pads by a stamp-assisted printing method. A woven textile of interlaced interconnectable OLED fibers with perpendicularly arranged conductive fibers serves as a matrix-addressable two-dimensional network that can be operated by the passive matrix scheme. Successful demonstrations of stably working woven OLED textile in the water, as well as under the applied tensile force, support feasibility of the present approach to reify fully addressable, environmentally durable, fiber-based textile displays.

Fibertronic有机发光二极管面向完全可寻址，环保且可穿戴的显示器。

电子纺织品在可穿戴应用中的巨大潜力引发了对智能纺织品显示器的发光纤维的积极研究。尽管在照明光纤技术方面取得了显着突破，但是由于存在一些严峻的挑战，例如电致发光光纤的性能有限，对化学和机械因素的严重脆弱性以及缺乏体面的工程方案，因此具有发光纤维网络的一类信息显示器仍未得到充分开发。形成具有健壮的可互连像素的光纤，用于二维矩阵寻址。这里，我们提出了一种用于有机发光二极管（OLED）纤维的纺织品显示器的高度可行的策略，该解决方案可以通过实施突出的解决方案选项来克服这些问题，这些解决方案包括在适应的光纤配置和化学/机械坚固但导电的情况下兼容OLED像素阵列的制造方法钝化系统。为了在不损害高电致发光性能的情况下创建可互连的固态OLED光纤，将磷光OLED材料沉积到矩形条纹的工艺友好型光纤上，在其中定期图案化的OLED像素用坚固的聚合物选择性地钝化，并通过压模辅助印刷方法避开金属焊盘。交织的可互连OLED纤维与垂直排列的导电纤维交织在一起的机织织物，可以作为可矩阵寻址的二维网络，可以通过无源矩阵方案进行操作。在水中以及在施加的拉力下稳定工作的OLED机织纺织品的成功演示，支持了本方法对完全可寻址，环保耐用的基于纤维的纺织品显示器进行尺寸化的可行性。
