Abstract

The present invention relates to a front-maintained multilayer magnetic-attaching LED display screen with small pitch. The structure of the present invention includes a planar array driving board containing light emitting diodes, pads having fixed interval are arranged around the planar array driving board, and the planar array driving board is fixedly connected to a first mounting board of a central fixed iron board to form a module. The module and the second mounting board are magnetically attached to form an outer layer magnetic-attaching structure, and the second mounting board are magnetically attached to the box or mounting member to form an inner layer magnetic-attaching structure; the magnetic force of the outer layer magnetic-attaching is smaller than that of the inner layer magnetic-attaching structure; a module assembly including at least two modules is magnetically attached by the box body or the mounting member.
