How to judge the quality of LED transparent screen? Some people say that through the appearance can roughly judge the quality of the box, is it really ?  Here are a few tips ..

1, Brightness comparison, the acrylic plate close to the same number of modules and then slowly lift a small distance, this time to see whether the brightness of the lamp beads can meet their requirements. Of course, the module is directly placed inside the word more direct, the higher the brightness of the lamp bead requirements are higher, the cost is relatively high.

The pure indoor environment can use low brightness, but if it is a window LED transparent screen or LED glass curtain wall screen, then it is necessary to seek truth from the bright LED transparent screen.

2, While watching the brightness, pay attention to whether the light of the lamp beads is uniform, and pay attention to whether there is a color difference when observing white light (this is very important) - if you use a thin white paper covered in the above may not be observed, so you should use a certain thickness of acrylic.

There is no color difference is the most important part of distinguishing quality, and it is also one of the main reasons for the price difference of LED transparent screen.

3, Wire discrimination.High-quality wire, through UL certification, these through the LED transparent screen manufacturer instructions are not reliable, so the most direct way is to peel off the skin, count the number of wire cores inside!Modules with 15, 17, 19 or even 20 or 30 cores should be no worse than modules with 14 or 11 cores, and vice versa.

5, Solder joint quality. The solder joint is full to prove that the welding process is good, and the high brightness proves that the solder is good. The serious is virtual welding, easy to appear poor contact phenomenon, follow-up maintenance trouble.

6, LED transparent screen lighting: At present, there are two production methods of LED transparent screen, one is positive light, one is side light.Although the permeability of the side light is relatively high, the performance is not stable, and the positive light bead is the traditional led display lamp bead, which has been tested by the market and the performance is very stable.
