Problems solved by technology
[0002] At present, with the development of society, LED billboards are more and more popular because of their strong versatility and bright colors. However, compared with traditional billboards, LED billboards have higher value and are more precise The environmental requirements are higher, and it is easy to be damaged if it is placed in the open air like ordinary billboards, so the display device becomes very important. Devices generally have defects such as inconvenient replacement and unsafe replacement. At the same time, most display devices are fixed devices, which are heavy and cost-effective. A small number of movable devices lack fixing means, which poses safety hazards.
