The high-speed rail display system has made a new design in industrial design and comprehensive information display interface design, focusing on the design to convey the new presentation and expression of railway information and visual interaction. The display screen adopts a double-sided display mode, and the concise suspension design modeling language is more in line with the current product design trend. The front and rear aluminum alloy materials are ultra-thin design. The middle frame cavity layout is used to form a hidden atmosphere lamp display groove. Three functional area modules are formed in the front and rear. The middle main body heat dissipation channel and the main load-bearing structure are designed to facilitate maintenance. The front and rear panels are composed of LED dot matrix screens to achieve a "full screen" visual effect. At the same time, the future expansion and economy of the design scheme are also considered. The partial modular design of the product solves the problems of different sizes and installation environments, saves the later production cost of the display screen, and improves the economic advantage and production efficiency.
