Adaptable display with spatial imaging, fostering advancements in extended reality with unconventional form requirements, is indispensable in scientific research, telemedicine, rescue, and space exploration. The adjustable photon spin angular momentum derived from chiral optical materials offer applicative lights for binocular stereo imaging displays, thus allowing an unimaginable immersive experience while maintaining awareness of surroundings. However, current chiral illuminant struggles to obtain adequate electroluminescence asymmetry during power-on display. Here, we present a designed self-positioning strategy to build new flexible spatial displays, integrating numerous multilayered circularly polarized electroluminescent microdevices, for real-time depth information control on the screen. With the devices' luminescence asymmetry value of up to 1.0 under electro-excitation, we visualize third-dimensional information using our chiral material-integrated tablet. Afterward, combined with a robot, we realize a series of remote human-machine interaction operations based on extended reality conditions. Our adaptable spatial display bridges the gap between virtuality and reality, making pioneering explorations in chiral luminous fields for extended reality and beyond.
具有空间成像功能的自适应显示器，能够满足非传统形式要求，推动扩展现实技术的发展，在科学研究、远程医疗、救援和太空探索中不可或缺。源自手性光学材料的可调光子自旋角动量为双目立体成像显示器提供了适用的光源，从而在保持对周围环境感知的同时，带来难以想象的沉浸式体验。然而，当前的手性发光体在通电显示期间难以获得足够的电致发光不对称性。在此，我们提出一种设计的自定位策略，以构建新型柔性空间显示器，集成众多多层圆偏振电致发光微器件，用于在屏幕上实时控制深度信息。通过这些器件在电激发下高达1.0的发光不对称值，我们使用集成手性材料的平板电脑可视化三维信息。随后，结合机器人，我们基于扩展现实条件实现了一系列远程人机交互操作。我们的自适应空间显示器弥合了虚拟与现实之间的差距，在手性发光领域为扩展现实及其他领域进行了开创性探索。
