For the front maintenance outdoor LED screen display module, the front maintenance of the outdoor LED screen locking mechanism is particularly important, because it will be related to the future maintenance of the whole outdoor LED screen body, and the final display effect of the whole outdoor LED screen body. Commonly used front maintenance display structures are the whole screen body surface with PC transparent board or transparent tempered glass board.

This method is not only inconvenient maintenance volume bulky, and used in outdoor surface reflection, display effect is not good and causes visual fatigue when people watch, this method is not recommended.

Another way is the way to wear a screw in the front of the outdoor LED screen display module, it is installed directly with the back of the box or frame for connection. Although this method solves the problem of maintenance, the outdoor LED screen display effect is greatly reduced, because its accuracy is too poor, it is easy to the mosaic phenomenon, and the bolt used in the outdoor time is easy to rust, this method is not the best solution.

In order to solve the above problems, now use the way of lock to make up for these aspects, its specific working principle: is installed in the back of the outdoor LED screen module a lock, the lock hole straight through the front of the module, and then through A key from the front of the outdoor LED screen module to complete the method of disassembly. This method can precisely locate the outdoor LED screen module and control the outdoor LED screen module. This method can precisely position the outdoor LED screen module and control the size of the force on the outdoor LED screen module, which effectively ensures The outdoor LED screen can be effectively displayed.

Outdoor LED screen module front lock hole bit need to do in the mask two sunshade brim in the middle of the upper bit, do not make the sunshade brim broken, otherwise, it is easy to lead to LED tube before fleeing light, a single module between the two pixels and other pixel contrast, there will be obvious color difference problems exist.
