Seven Ways To Identify The Quality Of Indoor LED Display Module A

Feb. 11, 2019

1, brightness comparison, the acrylic plate close to the same number of Indoor LED Display Module and then slowly increase the small distance, here to see whether the brightness of the lamp can meet their own requirements. Of course, putting the module directly in the word is more direct. The higher the brightness, the higher the requirement for the lamp bead. Chen is also relatively high. Pure indoor environment can use low brightness, but if it is a window LED transparent screen or Truck Mobile Advertising Led Display screen, then it is required to be a bright LED transparent screen.

2. While watching the brightness, pay attention to whether the light of the lamp is uniform. When observing the white light, be sure to notice 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. So use a certain thickness of acrylic. Whether there is color difference is the most important part to distinguish the quality, and it is also one of the main reasons leading to the price difference of LED transparent screen.

3, wire identification. High-quality wire, through UL certification, these manufacturers through the LED transparent screen are unreliable, so the most direct way is to open the skin and count the number of cores inside! Use 15, 17, 19 or even 20, 30 cores The module of the line should not be worse than the 14 and 11 core modules, and vice versa.
