Description
Technical field
The present invention relates to the technical field of LED display, more particularly, to a kind of preceding dimension of LED modules on LED display
Maintaining method and the LED display using this method.
Background technology
With the development of display screen technology, display applications field is more and more wider.High-definition display screen demand is more and more,
Large-scale display screen, is just gradually favored by user.The trend of LED display industry development is simple in construction, installation, maintenance side
Just.
In the prior art, large LED display screen typically uses rear maintenance mode or preceding maintenance mode.Maintenance mode is exactly afterwards
Maintenance work is in display screen followed by preceding maintenance mode is then that maintenance work is carried out from the front of display screen.
For the preceding maintenance mounting means of LED display, generally realized by the way of magnet adsorption and instrument gripping.
Mode of maintenance is before it：Iron block is installed in LED display modules, magnet is installed with LED display case, made by magnetic force
LED display modules are adsorbed with LED display case.The instrument for taking out module is a kind of hangnail type thin slice instrument, and this is inserted
