It uses a series of LED lamp beads to form pixels, and displays images or text information by controlling the brightness and color changes of each pixel. This display has the characteristics of high brightness, bright colors, and high resolution. It is suitable for various outdoor occasions, such as shopping malls, squares, stadiums, transportation hubs, etc.

[0003] Although LED display screens are usually equipped with support columns or fixing frames to fix them, when the LED display screens face natural factors such as strong winds, or human factors such as human collisions, the support frames are prone to tilting. Long-term use leads to material fatigue, which also easily causes the support frames to tilt, resulting in instability of the display screen, which is easy to cause damage to the display screen. The degree of tilt continues to accumulate, and eventually the LED display screen will topple over. Therefore, an LED display screen auxiliary righting device is proposed to address the above problems. Utility Model Content
