What is front maintenance LED screen?

The maintenance of LED display includes front maintenance and rear maintenance. The large-scale LED display used in rear maintenance is widely used in the outdoor application such as wall mounts LED screen and stand support LED screen. It must be designed with maintenance channel that people can maintain and repair from the back of the screen. The overall technical requirements are high, the installation is costly and waste a lot of time. For some applications such as inlaid LED screen and there is no space behind the LED screen, this is obviously not a suitable choice. That is why front maintenance is very popular now.

With the development in the LED screen industry, the pixel pitch of the LED screen is smaller and smaller. The indoor fine pitch LED display screen is going to dominate the market. It refers to the use of magnetic between the steel frame and the LED display screen to fix it. During operation, the suction cup directly contacts the surface of the box for front maintenance, thereby removing the module structure of the LED screen from its box and realizing the front maintenance screen. body. This pre-maintenance method can make the overall structure of the display screen thin and light, and integrate with the surrounding architectural environment, highlighting the indoor visual expression ability.

Compared with rear service, the advantage of front service LED screen is mainly to save space, and decrease the difficulty of rear maintenance work. The front maintenance does not need to prepare a maintenance channel, supports independent frontal maintenance, and saves the maintenance space on the back of the display. It does not need to disassemble the wire, supports rapid maintenance work, and disassembly is simpler and more convenient. The front-end maintenance requires a module structure that requires screws to be removed later. When a single point of failure occurs, only a single person needs to disassemble and maintain a single LED or pixel. The maintenance efficiency is high and the cost is low. However, due to the indoor high-density characteristics, the structure of this type of room-entry products has higher requirements for the heat dissipation of the cabinet, otherwise the display screen is prone to local failures.

Relatively speaking, rear maintenance is still widely used in different applications. Its price is slightly lower, suitable for installation scenarios such as rooftop and column type, and the inspection and maintenance efficiency is high. Due to different application scenarios, you can choose these two maintenance methods according to actual needs.
