Abstract

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.

能显示全彩图像和视频的集成电子纺织系统

具有显示等电子功能的智能电子纺织品可以为可穿戴设备提供传统刚性设备难以实现的变革机会。实现纺织品显示功能的一般策略是在纺织品中编织发光纤维并设计控制电路。然而，目前的电子纺织品要显示全彩色图像和视频仍然具有挑战性。在此，我们展示了一种大面积集成电子纺织品系统（尺寸为 72 厘米 × 50 厘米），该系统由发光二极管（LED）纤维、触摸感应纤维和聚酯纤维编织而成，通过设计低压供电模式和并行传输电路，可显示全彩色图像（色域为 117.6% NTSC）和连续视频（刷新率为 11.7 Hz）。集成触摸感应纤维后，这种纺织系统可以像智能手机或电脑一样实现各种触摸显示和互动功能，包括手写输入文字、手绘、计算和玩游戏。纺织系统的稳定性和耐用性也得到了验证，可承受 5000 次弯曲循环，适用于可穿戴应用。集成电子纺织系统显示出与普通纺织品相似的灵活性和透气性，有望成为新的人机界面，改变人们与电子产品的交互方式。
