Teach you how to judge the quality of LED transparent screen

2019-07-17 1254TIMES BACK

     LED transparent screen has been selling like a raging fire, and the manufacturers of LED transparent screen have been everywhere from few to now. How to judge the quality of LED transparent screen? Some people say that the quality of the box can be roughly judged by the appearance. Is that true? At present, many manufacturers produce transparent LED panels similar, even though the appearance is different, the structure is different. The principle is the same, circuit boards, beads, wires and so on. If we can find a good transparent LED display screen with our real gold eyes, Xiaobian will make a brief introduction here.

     1. Brightness comparison, the acrylic board will be closely attached to the same number of modules and then slowly raise a small distance, this time to see whether the brightness of the beads can meet their own requirements. Of course, it is more direct to put the module directly in the word. The higher the brightness, the higher the requirement for the lamp beads, and the higher the Chen Ben. Pure indoor environment can use low brightness, but if it is window LED transparent screen or LED glass curtain wall screen, then it requires a high brightness LED transparent screen can be.

     2. While looking at the brightness, we should pay attention to the uniformity of the light of the beads. When looking at the white light, we must pay attention to whether there is color difference (this is quite important) - if you cover it with a thin white paper, you may not see it, so you should use a certain thickness of acrylic. Colorimetric aberration is the most important part of distinguishing 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 through the LED transparent screen manufacturer instructions are unreliable, so the most direct way is to pull out the outer skin, count the number of cores inside! With 15, 17, 19 cores or even more than 20, 30 core modules should not be worse than 14, 11 core modules, and vice versa.

     4. bulb temperature. After lighting up for a period of time, touch the LED beads with your hand, the temperature is very high and even hot hands are certainly not as stable as low temperature.

     5. Weld joint quality. Full solder joint proves good welding technology, high brightness proves good solder use; serious is virtual soldering, prone to poor contact, follow-up maintenance troubles.

     6. LED transparent screen sticker mode: At present, there are two ways to make LED transparent screen, one is positive light, the other is side light. Although the side light transmittance is relatively high, the packaging technology of the lamp beads needs to be tested in the market, while the positive light-emitting lamp beads use the traditional LED display beads, which have been tested by the market and the quality is very stable.
