近年来，服装的作用已经从仅仅是身体保护、保持体温和时尚，发展到各种类型的信息传递、通信甚至增强现实等高级功能。通过无线互联网连接，电路和传感器的集成以及便携式电源，衣服成为一种新颖的电子设备。目前，信息显示器是使用可视化通信方法以及穿戴者与功能性衣服之间的输入和输出的同时并发处理的最直观的界面。在这种情况下，重要的方面是即使在将电子设备添加到柔性衣服时也保持织物的特性柔软性。硅基发光二极管（LED）夹克、衬衫和舞台服装已经开始出现，但无机半导体的固有刚度会导致穿着者感到不适;因此，很难将此类设备用于日常用途。为了解决这个问题，在这项工作中开发了一种利用有机发光二极管（OLED）制造薄且柔性的发光织物的方法。对其柔性进行了评价，对其机械弯曲特性进行了分析，并对其长期可靠性进行了试验。
Recently, the role of clothing has evolved from merely body protection, maintaining the body temperature, and fashion, to advanced functions such as various types of information delivery, communication, and even augmented reality. With a wireless internet connection, the integration of circuits and sensors, and a portable power supply, clothes become a novel electronic device. Currently, the information display is the most intuitive interface using visualized communication methods and the simultaneous concurrent processing of inputs and outputs between a wearer and functional clothes. The important aspect in this case is to maintain the characteristic softness of the fabrics even when electronic devices are added to the flexible clothes. Silicone-based light-emitting diode (LED) jackets, shirts, and stage costumes have started to appear, but the intrinsic stiffness of inorganic semiconductors causes wearers to feel discomfort; thus, it is difficult to use such devices for everyday purposes. To address this problem, a method of fabricating a thin and flexible emitting fabric utilizing organic light-emitting diodes (OLEDs) was developed in this work. Its flexibility was evaluated, and an analysis of its mechanical bending characteristics and tests of its long-term reliability were carried out.
