[0003] However, both of the two traditional display methods have certain limitations. For the flat display screen installed on the side wall of the carriage, due to the limitation of the installation position and the display angle, it can only cover the visual area on one side of the carriage. This means that passengers located on the other side or in the middle area of the carriage may not be able to clearly and intuitively see the arrival information displayed on the display screen, making it difficult for some passengers to obtain relevant information in the first time.

[0004] Although the front display screen can expand the information display range to a certain extent, in the case of passenger congestion in the carriage, especially when the carriage is full of passengers, passengers located in the middle and rear of the carriage need to pass through the standing crowd in front to observe the content on the display screen. This not only brings great inconvenience to passengers observing information, but also in the crowded carriage environment, passengers often have difficulty in smoothly completing this observation action, which leads to some passengers being unable to obtain vehicle arrival information in time, increasing the risk of over-station, and causing unnecessary trouble and trouble to passengers' travel.
