[0001] The utility model relates to the technical field of subway dispatching display screens, in particular to an LED display device for subway dispatching. Background Art

[0002] The subway dispatching display screen is used to display a lot of information about the subway, so the subway dispatching display screen usually requires a large screen. The existing subway dispatching LED display screen is usually composed of multiple small screens, and the height of the combined subway dispatching display screen is usually high, and the angle is fixed and cannot be flexibly adjusted. Although this fixed-angle design meets the basic display needs to a certain extent, in actual applications, especially in scenes with complex and changeable viewing environments, the fixed-angle LED display screen has problems such as poor viewing effect and inconvenience in use. In addition, when the subway dispatching display screen is used for a long time, dust is easily accumulated on the outer surface of the screen, which in turn affects the display effect of the display screen, so it needs to be cleaned regularly, and the existing cleaning structure generally wipes the screen by translating the cleaning block, and the angle cannot be adjusted, and the dead corners of the small screen combination and splicing are not cleaned thoroughly.

[0003] In order to solve the above problems, we propose an LED display device for subway dispatching that can adjust the angle of the display screen and clean up the blind spots of the display screen to ensure the display viewing effect of the display screen. Utility Model Content
