With the development of multimedia technology, LED electronic display screens are widely used in commercial display, resulting in good advertising effects, and the design of excellent display support structure can also become a beautiful landscape in urban buildings. In combination with the line-of-sight requirements of the display screen and the investment area, structural type design is usually carried out according to the construction site and building requirements. LED displays are usually placed in a stand-alone floor or in an attached building (Figures 1, 2). For the support structure of different display forms, the corresponding structural form should be accurately analyzed. The paper will classify and summarize the support structure of LED electronic display, and propose the applicable scope, design difficulties and corresponding Optimize design and construction measures.

1.1 floor-standing support structure
Floor-standing LED electronic displays are mostly located in city squares or important traffic intersections. It is known that the support structure of the landing display support structure should adopt the space steel truss structure. A set of four steel columns is combined to form a spatial lattice column. The upper screen body adopts a multi-layer horizontal space truss structure, which can meet the structural stress requirements and meet the maintenance channel settings.
Yiwu Binwang Road LED display screen area screen effective size is 13.4mx8.6 m, belonging to the typical floor-standing support structure, using lattice columns to form a display support structure system. The four main limbs of the steel lattice column are 300 mm×300 mm×10 mm, the horizontal horizontal material is 200 mm×100 mm×6 mm, and the diagonal web is 100 mm×100 mm×6 mm. The internal space of the lattice column is used to repair the upper passage; the screen back The side members are made of steel truss structure, the upper chord, the lower chord and the web are 100 mmx100 mmx6 mm, and the upper part is laid with 6 mm thick steel plate to meet the requirements of the access passage. The foundation is based on a separate concrete foundation. The support structure is shown in Figure 3.
