How to unit of choose and buy the LED panel?
manufacturers share the LED unit board knowledge of choose and buy!
Led unit board knowledge of choose and buy: the first: according to the module of lights, lamp bead raw material selection to pick the led unit board and encapsulation technology level is particularly important, it directly determine the merits of the led unit board product quality performance.
In addition, due to a variety of materials are different and the LED unit board light bead expansion coefficient is different from under the influence of external environment factors is easily broken gold wire connection, however the result is light and flash can lead to death, therefore, the LED unit board module lights, especially the key.
Second: according to the module of PCB will pick the LED unit board module to the technical requirement of the PCB is much higher than in other parts of the.
Now stable performance of the LED unit board module PCB generally consists of base material and the metal coating and integrated circuit.
But, in the application process, the external environment influences the quality of PC board board module link has a lot of, such as hole size and the thickness of the coating and the substrate material, etc.
As a result, users in the selection of the LED unit board process according to the module PCB application environment to consider.
Third: according to the module of the suite to reference the LED unit board module suite is the core of the door appearance on module structure, it can protect the lamp bead, unit board and key elements of joining together the whole screen.
And the LED unit board suite consists of mask, pan, positioning hole and install screw, etc. , but the LED unit board kit must be moistureproof, waterproof and uv protection, the stand or fall of the suite affect the flatness, contrast of the display and service life.
Not only that, the LED unit board module pouring sealant is also affect the display module performance of a very important link, potting glue paste degrees, corrosion resistance, uv resistance, not easy ageing, and strong in sealing characteristics can affect the application performance of the LED unit board module.
Thus, the user in the process of reliable reputation of choose and buy the LED unit board should pay attention to the selection mode.
are present in just about every facet of modern life.
