May 31,2021| LED Knowledge

Foreword:Usually we see more of how to buy LED displays. If we want to choose some LED modules to assemble or replace by ourselves, how should we choose? Let's take a look

Knowledge points of LED unit board purchase:

First: Choose according to the lamp beads of the module

The material selection and packaging process level of the lamp bead of the LED unit board is particularly important, which directly determines the quality of the LED unit board product. In addition, due to the differences 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 lead to 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

The technical requirements of the LED unit board module on the PCB board are much higher than other parts. Nowadays, the PCB board of the 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 module's PCB board in the process of selecting the LED unit board.

Third: refer to the module's package

The LED unit board module kit is the core structure of the outdoor surface mount module, which can protect the key elements of the lamp beads, the unit board and the entire screen splicing. 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. electronic display

Not only that, the potting glue of the 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 airtightness. 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.
