How to judge whether the LED Transparent Screen is good or bad? Some people say that the quality of the cabinet can be roughly judged by the appearance. Is that true? Even if the appearance is different, the construction principle is the same, such as circuit boards, lamp beads, wires, etc. How do we judge the pros and cons of transparent LED displays?
Brightness Comparison
Place the acrylic board close to the same number of LED modules. And then you can slowly raise a small distance to see if the brightness of the lamp beads can meet your 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 old version is relatively high. Pure indoor environment can use low brightness, but if it is a window Transparent LED Screen or LED glass curtain wall screen. So a bright LED transparent screen is required.
Is The Light Of The Lamp Beads Uniform
While watching the brightness, pay attention to whether the light of the lamp beads is uniform. When observing the white light, be sure to pay attention to whether there is any chromatic aberration (this is very important)-if you cover it with a thin white paper, it may not be observed, so Use a certain thickness of acrylic. The presence or absence of chromatic aberration is the most important part of distinguishing quality, and it is also one of the main reasons for the price difference of Transparent LED Screens.
Wire Identification
High-quality wire, UL certification. The manufacturer of the transparent LED screen is not necessarily reliable, so the most direct way is to peel off the outer skin and count the number of cores inside! Modules with 15,17,19 cores or even 20,30 mufti-core wires should be no more than 14 , 11-core module is poor, and vice avers.
Lamp Bead Temperature
After lighting up for a period of time, touch the LED lamp beads with your hand, the temperature is very high or even hot, it is certainly not as stable as the low temperature.
Solder Joint Quality
Additionally, the full solder joints prove that the soldering process is good. And the high brightness proves that the solder is used well; the more serious is the false soldering, which is prone to poor contact and troublesome follow-up maintenance.
LED Transparent Screen Sticking Method
Currently, there are two manufacturing methods for LED Transparent Screens, one is positive light-emitting and the other is side light-emitting. Although the side-emitting light has a relatively high transmittance, the packaging technology of the lamp bead needs to be tested by the market. And the positive-emitting lamp bead is the lamp bead of the traditional LED display. After the market test, the quality is very stable.
