Description

Technical Field

[0001] The present application relates to the field of display technology, and more specifically, to an anti-falling display device. Background Art

[0002] LED display module is the basic component unit of LED display, which is composed of multiple LED dot matrix and integrated with driving circuit. The module can be used alone or spliced ​​into a large-size LED display.

[0003] During the assembly of LED display screens, magnetic attraction and steel wire ropes are often used to fix the display module and the bracket (or box). Generally, a magnet is installed on the back of the display module, the display module is adsorbed on the bracket or box, and then the steel wire rope is used to fix it. When fixing, the steel wire rope is usually hooked and pulled to fix the module to prevent it from falling. This method will reduce the magnetic attraction after long-term use, and the module is easy to fall off due to external force. Although there is a steel wire rope hook, the module will still fall off the bracket or box, resulting in failure to work properly.

[0004] In some lower installation scenarios, it is common for modules to be manually pulled. Although there is a wire rope for hooking and pulling, the module can still be removed and lost. Utility Model Content
