In combination with Figure 1, when the LED display is installed on a higher wall, for example, as shown in Figure 1, the stadium has a first-floor stand 1 and a second-floor stand 2, and a wall 3 is arranged at the front end of the second-floor stand 2. The wall body 3 has the function of a railing, and can be called a parapet wall in the technical field of architecture. The LED display screen 4 is installed on the front side of the wall body 3, and is used for information dissemination, advertising and the like.

During the use of the LED display screen 4, it is inevitable to perform maintenance. The conventional maintenance method of the LED display is usually the front maintenance method or the rear maintenance method, that is, the maintenance work is performed on the front side or the rear side of the LED display screen. The inventor found that because the distance between the back of the LED display screen and the wall 3 is very small, maintenance access cannot be provided, and the LED display screen 4 cannot adopt the post-maintenance method; Auxiliary equipment such as scaffolding or a crane can only be maintained on the first-floor stand 1 . The maintenance work is tedious and complicated, and the cost is high; and the slope setting of the stand 1 on the first floor increases the difficulty of the front maintenance method, and the safety is low.

The inventor considers disassembling the LED display screen 4 from the left, right or bottom side for maintenance. The moving distance of the LED display screen 4 in the left and right directions is too large, and it is more difficult to realize the curved wall body 3; The LED display screen 4 still needs auxiliary equipment such as scaffolding or a crane.

For this reason, the inventor has found through careful research that the LED display 4 is disassembled from the top on the second-floor grandstand 2 without the need for auxiliary equipment such as scaffolding or a crane. The inventor has further developed a LED display screen that can be maintained from the top. The LED box of the LED display screen is slidably installed on the vertical guide rail vertically, so that the LED box can slide out from the top, and the disassembly is simple and convenient without using auxiliary tools such as scaffolding or cranes; and on the vertical guide rail The bottom end is provided with a support base to support the LED box, improving the stability and reliability of the LED box installation; the back of the vertical guide rail can be slidably installed on the horizontal slide rail, and the horizontal slide rail is fixed on the wall. The body can slide horizontally, making the installation and adjustment of the LED box simple and convenient.
