Technology丨The quality of the original LED transparent screen is judged like this

121 views admin 2020-12-09

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?

Brightness comparison

Place the acrylic board close to the same number of modules and then slowly raise it for a short distance, and watch whether 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 higher the cost. Pure indoor environment can use low brightness, but if it is a window LED transparent screen or LED glass curtain wall screen, then a bright LED transparent screen is required.

Is the lamp bead light 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 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.

Wire identification

High-quality wires have passed UL certification. These transparent LED screen manufacturers explain that they are unreliable, so the most direct way is to remove the sheath and count the number of cores inside! Use 15, 17, 19 cores or even 20, 30 cores The cable module should be no worse than the 14- and 11-core modules, and vice versa.

Lamp bead temperature

After lighting for a period of time, touch the LED lamp bead with your hand, the temperature is very high or even hot, it is certainly not as stable as the low temperature.

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.

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 positive-emitting lamp bead uses the lamp bead of the traditional LED display. After market inspection, the quality is very stable.
