Stretchable displays that combine light-emitting capabilities with mechanical compliance are essential building blocks of next-generation wearable electronics. However, their widespread applications are currently limited by complex device architecture, limited pixel density, and immature fabrication processes. In this study, we present the device design and material developments of intrinsically stretchable light-emitting drawing displays that can show arbitrary hand-drawing features. The alternating-current electroluminescent display uses a simplified architecture comprising coplanar interdigitated liquid metal electrodes, an electroluminescent layer, and a dielectric encapsulation layer. Ink patterns on the device are coupled with the interdigitated electrodes under alternating voltage stimulations, generating localized electric fields for bright emissions. Various inks are prepared for painting, stamping, and stencil printing. Arbitrary luminous features on the devices can be either long-lasting or transient in characteristics. These skin-like devices are made entirely of compliant materials that can withstand bending, twisting, and stretching manipulations. Due to the excellent mechanical deformability, the drawing displays can be conformally laminated on the skin as body-integrated optoelectronic communication devices for graphic information.

结合了发光功能和机械顺应性的可拉伸显示器是下一代可穿戴电子产品的重要组成部分。然而，它们的广泛应用目前受到复杂的设备架构、有限的像素密度和不成熟的制造工艺的限制。在这项研究中，我们介绍了可显示任意手绘特征的本质可拉伸发光绘图显示器的设备设计和材料开发。交流电致发光显示器使用简化的架构，包括共面叉指液​​态金属电极、电致发光层和介电封装层。设备上的墨水图案在交流电压刺激下与叉指电极耦合，产生局部电场以实现明亮的发射。为绘画、冲压和模板印刷准备了各种墨水。设备上的任意发光特征可以是持久的或瞬态的。这些类似皮肤的设备完全由柔顺材料制成，可以承受弯曲、扭曲和拉伸操作。由于具有优异的机械变形能力，绘图显示器可以保形地层压在皮肤上，作为图形信息的人体集成光电通信设备。
