Augmented reality (AR) near-eye display technology combines the virtual information and real worlds, creating a scene of virtual and real integration for users, becoming a bridge connecting reality and the virtual world.Retinal projection display (RPD), also known as Maxwellian displays, has received widespread attention in the field of AR near-eye display due to its ability to effectively resolve vergence-accommodation conflict and provide a near-eye display without dizziness. With the progress of research, Maxwellian near-eye display has multiple implementation methods, and different display methods have proposed different solutions around the main problems of expanding eye movement range and full-color display. This article mainly introduces the working principle of Maxwellian near-eye displays, summarizes the core devices used for Maxwellian near-eye displays and their development progress, and looks forward to the future development prospects and trends of Maxwellian near-eye displays.
