How to identify the quality of led transparent screen?

The led transparent screen is one of the most popular products in the led display. It has a wide range of applications and novel designs. It is usually used as a shop window, etc. Do you know how to identify the quality of the transparent led display? Let us know together

Brightness comparison

Put the acrylic board close to the same number of modules and slowly raise the distance by 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 requirements for the lamp beads, and the cost is relatively high. Pure indoor environment can use low brightness, but if it is a window LED transparent screen or an LED glass curtain wall screen, then a bright LED transparent screen is required.

Whether the light of the lamp beads is uniform

While watching the brightness, pay attention to whether the light of the lamp bead 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, you may not be able to observe it, 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 LED transparent screens.

Wire identification

High-quality wire, passed UL certification, and the LED transparent screen manufacturer’s instructions that do not pass are unreliable, so the most direct method is to open the outer skin and count the number of wire cores inside! Use 15, 17, 19 cores or even more than 20, 30 The module of the core wire should be no worse than the module of 14 and 11 cores, and vice versa.

lamp bead temperature

After lighting for a period of time, touch the LED lamp beads with your hand, the temperature is very high or even hot, and the stability is not as good as the low temperature.

Solder joint quality

The fullness of the solder joints proves that the welding process is good, and the high brightness proves that the solder is used well; the serious ones are virtual soldering, which is prone to poor contact and troublesome follow-up maintenance.

LED transparent screen sticker light method

At present, there are two production methods for LED transparent screens, one is positive light emission, and the other is side light emission. Although the transmittance of the side-emitting light is relatively high, the light-emitting lamp beads use the lamp beads of the traditional LED display. After market testing, the quality is very stable.
