Everyone knows that in the advertising LED Display, the basic unit that composes the display box unit is the LED unit board module. However, there are many types of LED unit board modules, so how do we choose a suitable LED unit board? We can select LED unit board modules according to the different surface treatment processes of the LED display. The details are as follows:
First: Choose according to the lamp beads of the module
The material selection and packaging technology level of the lamp beads of the advertising LED unit board is particularly important, which directly determines the quality of the LED unit board product. In addition, due to the difference in various materials at present, the expansion coefficient of the LED unit board lamp beads is different from the external environmental factors. It is easy to break the gold wire connection, but the result will cause dead lights and flashing lights. Therefore, The lamp beads of the LED unit board module are particularly critical.
Second: Choose according to the PCB of the module
Advertising LED unit board modules have much higher technical requirements for PCB boards than other parts. However, the PCB board of the current stable LED unit board module is generally composed of a substrate and a metal coating to form an integrated circuit. However, in the application process, there are many aspects of the external environment that affect the quality of the module PC board, such as the size of the through hole, the thickness of the coating, and the material of the substrate. Therefore, the user should consider the application environment of the PCB board of the module when selecting the LED unit board.
Third: Reference according to the package of the module
Advertising LED unit board module kit is the core structure of outdoor surface mount module, which can protect the key elements of lamp beads, unit board and splicing the whole screen. The LED unit board kit mainly includes a mask, bottom case, positioning holes and mounting screws, etc. However, the LED unit board kit must be moisture-proof, waterproof and UV-proof, and the quality of the kit affects the flatness, contrast and use of the display life.
Not only that, the potting glue of the advertising LED unit board module is also a very important link that affects the performance of the display module. The potting glue has the characteristics of adhesion, corrosion, UV resistance, resistance to aging, and strong air tightness. It can affect the application performance of the LED unit board module. It can be seen that users should pay attention to the above-mentioned selection method when purchasing a reliable LED unit board.
