LED transparent screens have been sold in full swing, and LED transparent screen manufacturers have grown from a few to now. How to judge the quality of LED transparent screens? Some people say that the quality of the cabinet can be roughly judged by the appearance. Is this really the case? The transparent LED panels produced by many manufacturers are similar, even if the appearance is different, the construction principle is the same, such as circuit boards, lamp beads, wires, etc. If you can find a good transparent led display with our Fire Eye Real Gold, the editor will give a brief introduction here:

2. While viewing the brightness, pay attention to whether the light of the lamp beads is uniform, and when observing the white light, be sure to pay attention to whether there is any color difference (this is quite important)-if you cover it with a thin white paper, you may not be able to observe it. , So use a certain thickness of acrylic. The presence or absence of 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 screens.
3. Wire identification. High-quality wires, through UL certification, these transparent LED screen manufacturers explain that they are not reliable, so the most direct way is to peel off the outer skin and count the number of cores inside! Use 15,17,19 cores or even 20, 30 cores The cable module should not be inferior to the 14- and 11-core modules, and vice versa.
4. 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.
5. Solder joint quality. 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.
6. LED transparent screen sticking method: currently there are two production methods for LED transparent screen, one is positive light and the other is side light. Although the side-emitting light has a relatively high transparency rate, the packaging technology of the lamp beads is yet to be tested by the market, and the positive-emitting lamp beads are those of the traditional LED display. After market inspection, the quality is very stable.
7, PCB board thickness. If the positive-emitting PCB board is thicker, it will affect the transmittance of the LED transparent screen.
