How to identify the quality of LED transparent screens

As a new type of display technology, LED transparent screens are highly sought after by the market due to their unique transparent characteristics and flexible application scenarios. However, facing many LED transparent screen manufacturers and products, how can consumers judge their quality? This article will provide some practical judgment criteria and methods to help users select high-quality LED transparent screens.

Brightness comparison

Brightness is one of the important indicators to measure the performance of LED transparent screens. Users can observe whether the brightness of the lamp beads meets the expected requirements by placing the acrylic plate close to the module and slowly raising it a certain distance. For indoor environments, low-brightness transparent screens can meet the needs, while for outdoor applications such as windows or curtain walls, high-brightness LED transparent screens are required. Here is the knowledge about nit brightness.

Light uniformity and color difference

While evaluating the brightness, it is also necessary to pay attention to whether the light of the lamp beads is uniform, especially when observing white light, to check whether there is color difference. Color difference is an important factor affecting the quality of LED transparent screens and one of the main reasons for price differences. Using acrylic sheets of a certain thickness instead of thin paper to cover can more accurately observe color difference. Here is an introduction to the working principle of LED lamp beads.

Wire quality

High-quality wires are usually UL certified, but the manufacturer's instructions alone are not reliable. Users can directly peel off the outer skin of the wire and count the number of inner cores to judge the quality of the wire. The more cores, the better the quality of the wire.

Lamp bead temperature

After lighting the LED transparent screen for a while, you can feel its temperature by touching the lamp bead. If the temperature is very high or even hot, it means that its stability is not as good as the product with lower temperature. Here are 3 specifications of LED lamp beads.

Solder joint quality

The fullness of the solder joint reflects the quality of the welding process. High brightness indicates that the quality of the solder used is good. On the contrary, if there is a cold solder joint, it may cause poor contact and increase the trouble of subsequent maintenance.

Lamp mounting method

There are two main ways to make LED transparent screens: positive light and side light. Although the side light has a higher transparency, its lamp bead packaging technology still needs market verification. The positive light lamp beads use the lamp beads of traditional LED display screens. After market testing, the quality is more stable.

PCB board thickness

For positive light LED transparent screens, if the PCB board is too thick, it will affect the transparency of the screen. Therefore, choosing a PCB board of appropriate thickness is also an important factor in judging the quality of the transparent screen.

Conclusion

When choosing a transparent LED screen, users need to consider multiple factors, including brightness, light uniformity, color difference, wire quality, lamp bead temperature, solder joint quality, lamp mounting method, and PCB thickness. Through careful comparison and evaluation, users can more accurately judge the quality of transparent LED screens and make wise purchasing decisions. With the continuous advancement of technology and the increasing maturity of the market, high-quality transparent LED screens will bring users a better visual experience and application value.
