具有自供电功能的柔性透明显示器对于物联网（IoT）中的人工电子皮肤和信息通信至关重要。在这里，我们提出了一个自供电的柔性显示系统，通过集成的透明交流电致发光（ACEL）器件与摩擦纳米发电机（TENG），共享公共透明电极。以ZnS：Cu@PDMS为发光层，单壁碳纳米管（SWCNTs）为透明电极，ITO/PET为衬底，制备了透明ACEL。获得了由ITO和PDMS两层透明摩擦层组成的TENG，其开路电压为200 V，短路电流为6 µA，可以很容易地点亮ACEL器件。轻轻按下自供电柔性透明显示系统，立即形成“ZZU”图案阵列。该集成系统在几乎整个可见光区呈现出80%以上的高透射率。这项工作在人机交互、人工电子皮肤和物联网中的自供电通信中具有相当大的潜在应用。
Flexible transparent displays with self-powered features are crucial for artificial electronic skins and information communication in the internet of things (IoT). Here, we present a self-powered flexible display system by integrating the transparent alternating current electroluminescence (ACEL) device with a triboelectric nanogenerator (TENG), sharing the common transparent electrode. The emissive layer of ZnS:Cu@PDMS is sandwiched by transparent electrodes of single-wall carbon nanotubes (SWCNTs) and ITO/PET substrate to prepare transparent ACELs. The TENG composed of two transparent tribo-layers ITO and PDMS is obtained and demonstrates an open-circuit voltage of 200 V and a short-circuit current of 6 µA, which can easily light up ACEL devices. A ‘ZZU’ pattern array is instantly carried out by gently pressing the self-powered flexible transparent display system. The integrated system renders high transmittance over 80% in almost the entire visible region. This work possesses considerable potential applications in human-machine interactions, artificial electronic skins, and self-powered communications self-power communication in the IoT.
