Displays play a significant role in delivering information and providing visual data across all media platforms. Among displays, the prominence of reflective displays is increasing, in the form of E-paper, which has features distinct from emissive displays. These unique features include high visibility under daylight conditions, reduced eye strain and low power consumption, which make them highly effective for outdoor use. Furthermore, such characteristics enable reflective displays to achieve high synergy in combination with wearable devices, which are frequently used for outdoor activities. However, as wearable devices must stretch to conform to the dynamic surfaces of the human body, the issue of how to fabricate stretchable reflective displays should be tackled prior to merging them with wearable devices. In this paper, we discuss stretchable and reflective displays. In particular, we focus on reflective displays that can be divided into two types, passive and active, according to their responses to stretching. Passive displays, which consist of dyes or pigments, exhibit consistent colors under stretching, while active displays, which are based on mechanochromic materials, change their color under the same conditions. We will provide a comprehensive overview of the materials and technologies for each display type, and present strategies for stretchable and reflective displays.

可拉伸和反光的显示器：材料，技术和策略。

显示器在跨所有媒体平台传递信息和提供可视数据方面发挥着重要作用。在显示器中，以电子纸的形式，反射型显示器的重要性正在增加，其特征与发射型显示器不同。这些独特的功能包括在日光条件下的高能见度，减少的眼睛疲劳和低功耗，这使其非常适合户外使用。此外，这种特性使得反射型显示器与经常用于户外活动的可穿戴设备相结合，可以实现高协同作用。然而，由于可穿戴设备必须拉伸以顺应人体的动态表面，因此在将可拉伸反射显示器与可穿戴设备合并之前应解决如何制造可拉伸反射显示器的问题。在本文中，我们讨论可拉伸和反射式显示器。特别是，我们专注于反射型显示器，根据其对拉伸的响应，可分为被动型和主动型两种。由染料或颜料组成的无源显示器在拉伸下表现出一致的颜色，而基于机械变色材料的有源显示器在相同条件下会改变其颜色。我们将提供每种显示器类型的材料和技术的全面概述，并提供可拉伸和反射式显示器的当前策略。基于机械变色材料，它们在相同条件下会改变颜色。我们将提供每种显示器类型的材料和技术的全面概述，并提供可拉伸和反射式显示器的当前策略。基于机械变色材料，它们在相同条件下会改变颜色。我们将提供每种显示器类型的材料和技术的全面概述，并提供可拉伸和反射式显示器的当前策略。
