How to judge the quality of LED transparent panel? Practical method recommendation
How to judge whether the LED transparent pannel is good or bad? Some people say that the quality of the pannel can be roughly judged by the appearance. Is this really true? At present, many manufacturers produce transparent LED panels similar, even if the appearance is different, the construction principle is the same, circuit boards, lamp beads, wires and so on. Therefore, it is only judged by the appearance that it is not good or bad. You also need to identify it by the following means:

1, brightness comparison, the acrylic plate close to the same number of modules and then slowly increase the small distance, here to see whether the brightness of the lamp can meet their own requirements. Of course, it is more straightforward to put the module directly in the word.

2. While viewing the brightness, the light of the lamp bead is uniform. When observing the white light, you must pay attention to whether there is any color difference (this is very important). If you cover it with a thin piece of white paper, you may not observe it. Use a certain thickness of acrylic. Whether or not there is color difference is the most important part to distinguish the quality of transparent display, and it is also one of the main reasons for the price difference of LED transparent screen.
 
3, wire identification. High-quality wire, passed UL certification, these are not reliable through the LED transparent screen manufacturer, so the most direct way is to open the skin and count the number of cores inside! Modules with 15, 17, 19 or even 20 and 30 cores should not be worse than modules with 14 or 11 cores, and vice versa.
 
4, the lamp temperature. After lighting for a period of time, touch the LED lamp bead by hand. The temperature is very high and even the hot hand is definitely not stable with low temperature.
 
5, solder joint quality. You can directly check the soldering of the lamp bead. The solder joint is full and the soldering process is good. The high brightness proves that the solder is good. The serious one is the solder joint, which is prone to contact failure and subsequent maintenance trouble.
 
In addition to the above aspects, LED transparent screen pannel also need to identify ICs and auxiliary components. It is much easier to judge some professionals. As the first-class LED transparent screen enterprise in China,Shenzhen VTEAM only produces medium and high-grade products. The industry has accumulated a number of excellent cases and good reputation. Welcome to consult!
