The development of electroluminescent (EL) devices that are deformable through bending, folding, rolling, twisting, or stretching or conformable to a substrate with an arbitrary surface contour has progressed steadily in recent years. In this review, the development of deformable alternating current (AC) powder EL devices is explored. First, the fundamental physics and the architecture of EL devices are introduced, followed by a discussion of the factors influencing the performance of the devices. Second, state-of-the-art flexible and stretchable AC powder EL devices are described and evaluated in detail, and the current status of research into deformable EL devices is outlined. Finally, the bottlenecks in the development high-performance conformable AC powder EL devices are identified, and key future research challenges are highlighted.

近年来，可通过弯曲，折叠，滚动，扭曲或拉伸而变形或可适应具有任意表面轮廓的基板的电致发光（EL）器件的开发稳步发展。在这篇综述中，探索了可变形交流（AC）粉末EL器件的开发。首先，介绍了EL器件的基本物理原理和体系结构，然后讨论了影响器件性能的因素。其次，详细描述和评估了最新的柔性可拉伸AC粉末EL器件，并概述了可变形EL器件的研究现状。最后，确定了高性能高性能交流粉体EL器件的瓶颈，并指出了未来的主要研究挑战。
