In this study, a method to construct a full-colour volumetric display is presented using a commercially available inkjet printer. Photoreactive luminescence materials are minutely and automatically printed as the volume elements, and volumetric displays are constructed with high resolution using easy-to-fabricate means that exploit inkjet printing technologies. The results experimentally demonstrate the first prototype of an inkjet printing-based volumetric display composed of multiple layers of transparent films that yield a full-colour three-dimensional (3D) image. Moreover, we propose a design algorithm with 3D structures that provide multiple different 2D full-colour patterns when viewed from different directions and experimentally demonstrate prototypes. It is considered that these types of 3D volumetric structures and their fabrication methods based on widely deployed existing printing technologies can be utilised as novel information display devices and systems, including digital signage, media art, entertainment and security.
在本研究中，提出了一种使用商用喷墨打印机构建全彩色立体显示器的方法。光反应性发光材料作为体素被精细且自动地打印出来，并且利用易于制造的方式，借助喷墨打印技术以高分辨率构建立体显示器。实验结果展示了基于喷墨打印的多层透明膜立体显示器的首个原型，该原型可产生全彩色三维（3D）图像。此外，我们提出了一种具有3D结构的设计算法，当从不同方向观察时，该结构能提供多种不同的2D全彩色图案，并通过实验展示了原型。据认为，这些基于广泛应用的现有打印技术的3D立体结构及其制造方法可被用作新型信息显示设备和系统，包括数字标牌、媒体艺术、娱乐和安全领域。
