Near-eye displays, which seamlessly integrate the digital and physical worlds, are expected to become the next generation of augmented reality display terminals. Retinal projection displays (RPD) technology is one of the research hotspots in the field of near-eye display due to its advantages of convergence-conflict free, high light efficiency and large field of view. In this paper, the development of RPD technology is reviewed, the basic working principle of RPD is described, the latest progresses of RPD and its eyebox expansion are reviewed, and the future prospect of RPD is forecasted. In the future, by combining the advantages of holographic wavefront control and holographic optical element (HOE), it is expected to realize a lightweight RPD near eye display with large eyebox and high system freedom.
