Title:
MULTI-LAYER MAGNETIC ATTACHING, FRONT-MAINTENANCE TYPE LED DISPLAY HAVING SMALL DOT PITCH
Document Type and Number:
WIPO Patent Application WO/2017/063319
Kind Code:
A2
Abstract:
The present invention relates to the technical field of LED devices, and relates to an LED display having a small dot pitch, in particular to a multi-layer magnetic attaching, front-maintenance type LED display having a small dot pitch. The structure of the present invention comprises a planar array drive board comprising light emitting diodes; the planar array drive board is provided at the perimeter with cushion blocks arranged in a fixed interval; the planar array drive board and a first installation board of a central fixing iron board are fixedly connected and form a module; the module and a second installation board form an external magnetic attachment structure by means of magnetic attachment; the second installation board and a box or an installation component form an internal magnetic attachment structure by means of magnetic attachment; the magnetic force the external magnetic attachment structure is weaker than the magnetic force of the internal magnetic attachment structure; a modular assembly formed by at least two modules magnetically attached to the box or the installation component. The present invention enables easy and quick assembly and disassembly, solves the post-installation problem of minute offset and pressing of magnetic attaching modules having a weak magnetic force, and addresses the difficulty in flatness adjustment and modular gaps due to modules being fixed onto a box or an installation component.
