At present, the use of surface-mount SMD displays in the market has become the mainstream and mature product of indoor displays, and the performance of display equipment failures is different due to the impact of different use environments. As a manufacturer, how can the protection level of the indoor display be enhanced to reduce the failure rate? Display manufacturers analyze from the following aspects.

After 72 hours of aging process, the light board made by the surface mount (SMT) process is coated on the surface of the light board to form a so-called protective layer, which can wrap the conductive pins to isolate moisture and water. Influence. It can effectively prevent the occurrence of problems such as failure points caused by moisture and dust, and at the same time can provide the effect of protection against bumps.

For LED display products with a general protection level of IP40 (IPXX, front X dustproof, rear X waterproof), it has the technology to effectively improve the protection level of the LED lamp surface, provide anti-collision effect, avoid the occurrence of lamp drop, and reduce the whole screen damage This type of solution has already responded to market demand and has mature production, and will not excessively increase the overall cost burden.

Not only that, the protection process on the back of the printed circuit board maintains the three-proof paint protection process used in the past. Generally, the spraying process can improve the protection level of the back of the circuit board and form a surface coating film on the surface of the integrated circuit. Protective layer to avoid failure of integrated circuit components of the drive circuit.
