摘　　要：Smart electronic textiles with electronic functions like displaying can provide transformative opportunities for wearable devices that traditional rigid devices are hard to realize.A general strategy of enabling textiles to display is weaving light-emitting fibers into textiles and designing control circuits.However,it remains challenging for the current electronic textiles to display full-color images and videos.Here,we demonstrate a large-area integrated electronic textile system(with a size of 72 cm×50 cm)by weaving light-emitting diode(LED)fibers,touch-sensing fibers and polyester fibers,which could display full-color images(with a gamut of 117.6%NTSC)and continuous videos(with a refresh rate of 11.7 Hz)by designing low-voltage supply mode and parallelly transmitting circuits.After integration of touch-sensing fibers,such textile system could achieve various touch display and interactive functions like smart phones or computers,including hand input of text,hand painting,computing and playing games.The stability and durability of textile system withstanding 5000 bending cycles was also demonstrated for wearable applications.The integrated electronic textile system shows similar flexibility and breathability with regular textiles,which is promising to serve as new human-machine interface to change the way in which people interact with electronics.具有显示等功能的智能电子织物有望为可穿戴设备带来传统刚性器件所无法实现的变革性发展机遇.赋予织物以显示功能的一个经典方法,是将发光纤维编织成织物,并通过设计驱动电路而实现显示.然而,目前电子织物面临的一个重要挑战是难以显示全色彩图片和视频.为此,我们通过将LED发光纤维、触摸感应纤维和涤纶纤维进行编织,制备得到了大面积的集成电子织物系统(尺寸为72 cm×50 cm).通过设计低压供电模式和数据并行传输电路,该织物系统可实现全色彩图片(色域达117.6%NTSC)和视频(刷新率为11.7 Hz)显示.通过集成触摸感应纤维,该织物系统可实现像智能手机和电脑一样的触控交互功能,如手写输入文本、绘画、计算器和游戏.面向可穿戴应用需求,该织物系统具有良好的稳定性和耐久性,可经受5000次弯曲变形测试.该集成电子织物系统还具有与传统织物相近的柔性和透气性,有望作为一种新型人机交互界面,改变人们与电子器件的交互方式.
