When purchasing LED display screens, we often hear the terms "front maintenance" and "back maintenance". So, what is the difference between these two maintenance methods? How to buy it? Let's take a look at it:
The back maintenance modules are mostly used for large outdoor/exterior LED display screen of building exterior wall. Maintenance channels must be set behind the screen to meet the daily maintenance and repair needs. Therefore, the installation is cumbersome, which is not only time-consuming and laborious, but also has higher overall technical requirements. Obviously, this method is not suitable for indoor applications with compact space.
With the increasing popularity of small-pitch LED screens, front maintenance has gradually become the mainstream of indoor display screens. The front maintenance usually means that the LED display cabinets are fixed by magnetic adsorption screws in front of modules, and when maintenance is needed, the modules to be maintained can be removed from the front of the cabinet. This method can not only make the screen thinner and lighter, save space, but also make the maintenance very convenient, so it is increasingly favored by users. In short, the two methods have their own advantages. For example, the price of back maintenance products is lower, and the efficiency of inspection and maintenance is higher.So it is a more economical in outdoor buildings with large screens, roof-mounted and column-mounted installations, etc. The advantages of front maintenance are that it saves space and are easier for maintenance, especially for those indoor installations that cost a lot of money. Moreover, it is more convenient to disassemble and assemble, especially suitable for rapid maintenance in case of single-point failure. It should be noted that the front maintenance/service/access products are usually of high density, and special attention should be paid to ventilation and heat dissipation to avoid affecting normal use.
