“According to technology media news reporters, augmented reality (AR) near eye display technology is becoming a bridge connecting the real and virtual worlds. This technology can superimpose virtual information onto the real world, creating a scene that combines reality and virtuality. Among them, Retinal Projection Display (RPD), as a type of Maxwell's near eye display, can effectively solve the focus convergence conflict and provide a near eye display experience without dizziness, thus attracting much attention. In recent years, numerous research teams have proposed various solutions around core issues such as expanding the exit pupil and full-color display. This article provides a detailed introduction to the working principle of Maxwell enhanced AR near eye display, summarizes the development history of its key components, and looks forward to future prospects and trends. The continuous advancement of this technology will bring new breakthroughs to the AR field and bring more diverse experiences to people's lives.”
