The connection surface of the LED soft module special-shaped screen is different from the traditional display. Traditional PCB boards are made of glass fiber materials, while the flexible modules are equipped with high-strength locking and linking devices, and flexible FPC circuits made of flexible insulating substrates. Plates, masks and bottom shells are made of rubber, with high strength resistance to compression and torsion, which can perfectly solve the difficult installation problems of various corners and corners. The installation methods are mostly based on magnetic column suction. The installation method is "install as soon as possible", that is, the customization of the shape is completed according to the customer's needs, and then it can be directly adsorbed to achieve one-step installation. The installation method of magnetic attraction is as simple as the conventional indoor screen installation method, and the box connection lines are connected by quick butt joints, which is firm and reliable. The development of soft modules has become an irresistible trend in the market.
