Virtual reality (VR) and augmented reality (AR) are revolutionizing the ways we perceive and interact with various types of digital information. These near-eye displays have attracted significant attention and efforts due to their ability to reconstruct the interactions between computer-generated images and the real world. With rapid advances in optical elements, display technologies, and digital processing, some VR and AR products are emerging. In this review paper, we start with a brief development history and then define the system requirements based on visual and wearable comfort. Afterward, various VR and AR display architectures are analyzed and evaluated case by case, including some of the latest research progress and future perspectives.

虚拟现实 (VR) 和增强现实 (AR) 正在彻底改变我们感知各种类型数字信息并与之交互的方式。这些近眼显示器由于能够重建计算机生成的图像与现实世界之间的相互作用而引起了极大的关注和努力。随着光学元件、显示技术和数字处理的快速发展，一些虚拟现实和增强现实产品不断涌现。在这篇评论文章中，我们从简要的发展历史开始，然后根据视觉和可穿戴舒适度定义系统要求。随后，对各种 VR 和 AR 显示架构进行了案例分析和评估，包括一些最新的研究进展和未来展望。
