In this paper, a high‐performance electrochromic optical shutter (ECOS) based on fluoran dye and an augmented reality (AR) display system comprising of ECOS are proposed. The electrochromic reactions of the fluoran dye that transmit or absorb visible light depending on its redox state are activated by the protons generated from hydroquinone derivatives, thereby significantly improved visible light absorption and decreased driving voltage. The visible light‐absorbing function of ECOS is a sole solution for overcoming the main issue of low visibility of displayed images under strong ambient light conditions in optical see‐through head‐mounted displays (OST‐HMDs) implementing augmented reality. The proposed AR display effectively solves the problem by significantly increasing the ambient contrast ratio and color gamut of the displayed image on OST‐HMD even in the strong ambient light condition due to the excellent visible light‐absorbing function of ECOS.

基于荧光染料的高性能电致变色光学快门，用于增强现实显示的可视性

本文提出了一种基于荧光染料的高性能电致变色光学快门（ECOS）和一种由ECOS构成的增强现实（AR）显示系统。取决于其氧化还原状态而透射或吸收可见光的荧光染料的电致变色反应被氢醌衍生物产生的质子激活，从而显着改善了可见光吸收并降低了驱动电压。ECOS的可见光吸收功能是唯一的解决方案，可解决实现增强现实的光学透视头戴式显示器（OST-HMD）在强环境光条件下显示图像的低可见性这一主要问题。
