一种能够在发射和反射两种模式下工作的双模显示装置，具有两种模式的优点，作为下一代显示器具有相当大的前景。在这篇综述中，电化学开关系统，能够同时控制发射和显色，以创建新的显示材料进行了综述。将重要的镧系（III）配合物之一铕（III）[Eu (III)]发光配合物与紫素衍生物的电致变色分子相结合，形成多功能化结构。铕（III）配合物的发射是由紫紫衍生物的电致变色作用通过分子间能量转移机制控制的。当紫色衍生物处于无色状态时，从Eu （III）配合物中观察到强烈的红色发射。另一方面，电化学着色的紫外光衍生物有效地淬灭了Eu （III）配合物的红色发射。然而，这些系统缺乏快速响应和高可逆性的荧光调制。介绍了为改善这些不足而进行的一些研究。此外，还实现了发射和反射模式下的数字表示和多色表示。
A dual-mode display device which can operate in both emissive and reflective modes, having advantages of both modes, is considerable promise as a next generation display. In this review, electrochemical switching systems, which enable simultaneous control of both emission and coloration, are reviewed in order to create the novel displaying materials. A luminescent europium (III)[Eu (III)] complexes, one of the important lanthanide (III) complexes, and electrochromic molecules of viologen derivatives were combined for appearance of the multi-functionality. The Eu (III) complex emission was controlled by the electrochromism of the viologen derivatives via an intermolecular energy transfer mechanism. When viologen derivatives were in a colorless state, a strong red emission was observed from the Eu (III) complex. On the other hand, the electrochemically colored viologen derivatives effectively quenched the red emission of the Eu (III) complex. However, these systems lacked quick response and high reversibility of the fluorescence modulations. Some of the researches for improving these disadvantage of primary study are described. Furthermore, numerical representations and multi-color representations with emissive and reflective modes were also achieved.
