Application research and prospect of screenless display technologies in railway intelligent station

With the development of display technology, screenless display technology represented by augmented reality (AR) technology, virtual reality (VR) technology, intelligent projection technology and (pseudo) holographic technology, in the construction of smart stations, can be used in passenger identity verification, equipment inspection, staff training, onsite navigation and passenger service. This paper first classifies and summarizes the technical principles of several screenless display technologies, and elaborates on specific technologies in detail. Subsequently, we have combed and summarized the application of several screenless display technologies in railway intelligent passenger stations in detail. Based on the actual demand of railway passenger stations, according to the current situation and limitations of the use of screen display technology in railway station equipment operation and maintenance and passenger services, we can try to study and apply new screenless display technologies, such as AR, VR and intelligent projection to improve the intelligence level of railway stations.
