A clothing-type wearable display can be utilized in fashion, bio-healthcare, and safety industries as well as smart textiles for the internet of things (IoTs) and wearable devices. In response to this trend, we demonstrate a textile display that can endure the active movements of a human body. It can be applied to any kind of textile, and is durable against conditions such as rain, sweat, and washing. As a key technology for realizing the multi-directional wrinkle-able textile display, we fabricated a stress-lowering textile platform with an ultrathin planarization layer replicated from the flat surface of glass. An elastomeric strain buffer for reducing mechanical stress is also inserted into the textile platform. Here, organic light-emitting diodes (OLEDs) with red, green and blue color, thin film transistors (TFTs) fabricated at a low temperature below 150 °C, and a washable encapsulation layer blocking both gas and liquid were demonstrated on the textile platform.

用于服装型显示器的多方向可起皱纺织品OLED

服装式可穿戴显示器可用于时装,生物保健和安全行业,以及用于物联网(IoT)和可穿戴设备的智能纺织品。为响应这种趋势,我们展示了一种可以承受人体主动运动的纺织品展示。它可以应用于任何类型的纺织品,并且在雨水,汗水和洗涤条件下具有持久性。作为实现多方向可折皱纺织品展示的关键技术,我们制造了一种具有降低应力的纺织品平台,该平台具有从玻璃平面复制的超薄平面化层。用于减小机械应力的弹性应变缓冲器也被插入到纺织平台中。在这里,红色,绿色和蓝色的有机发光二极管(OLED)
