Technology | Modules vs. cabinets, which one is the best choice?

In the construction of indoor LED display screens, modules and cabinets are common choices, and each has its own advantages and disadvantages. The following is a detailed analysis to help you make the right choice.

1.Display effect

The module size is small, the number of splicing is large, and manual splicing is prone to cause seams and unevenness, and the defects are more obvious when displaying a large area.

The box size is large and the number of splicing is small, which can better ensure the overall flatness, better display effect, and more natural picture transition.

2. Installation and maintenance

The modules are mostly installed by magnetic suction, which is flexible to install. However, the large screen may be affected by thermal expansion and contraction after long-term use, which may cause the seams to be misaligned. The back of the display screen spliced by the modules needs to be closed separately, which is not safe and aesthetically pleasing. It is mostly maintained from the front, and a channel needs to be left for rear maintenance.

The box is usually fixed with screws, which is stable and less affected by external factors. It can also be made into front maintenance, which is convenient for disassembly and later maintenance in occasions where it needs to be disassembled frequently.

3. Cost considerations

The module technology is mature and widely used. The initial installation and after-sales replacement and maintenance costs are low, and the repair or replacement of individual lamp beads is cheap.

The box is a highly integrated structure, using materials such as die-cast aluminum, and the cost investment is slightly higher than the module.

4. Applicable scenarios

For indoor display screens with a pitch greater than P1.8, regardless of the size, it is more cost-effective to use module splicing. If the small pitch screen is larger than 20 square meters, it is recommended to use a box structure splicing; if it is less than 20 square meters, module splicing is more suitable.

When the cabinet is installed on the floor and the back is not closed, the cabinet splicing is more beautiful and practical; for occasions with high requirements on display effect and stability, the cabinet has obvious advantages.

In short, whether to choose a module or a cabinet for indoor LED lighting requires a comprehensive consideration of display effects, installation and maintenance, cost, and usage scenarios. If you pursue high cost performance and do not require extreme display details, the module is a good choice; if you focus on display quality and installation and maintenance convenience, the cabinet can better meet your needs.
