LED transparent screens are selling like hotcakes, and manufacturers have sprung up everywhere. How can you judge the quality of an LED transparent screen?
Some say you can roughly judge the quality of the enclosure by its appearance. Is this true?
Currently, many manufacturers produce similar transparent LED panels. Even if the appearance differs, the underlying construction principles are the same: circuit boards, LED chips, wiring, etc.
Below, an LED display manufacturer provides a simple guide for judging quality:
1. While observing the brightness, pay attention to whether the light from the LED chips is uniform. When observing white light, pay close attention to any color difference (this is extremely important)—you might not be able to see it if you cover it with a thin sheet of white paper, so you need to use acrylic of a certain thickness. The presence or absence of color difference is the most important part of distinguishing quality and one of the main reasons for the price difference of LED transparent screens.
2. Wiring identification. High-quality cables, UL certified, are unreliable according to LED transparent screen manufacturers. Therefore, the most direct method is to peel back the outer sheath and count the number of wires inside! Modules using 15, 17, 19, or even 20 or 30+ cores should not be inferior to modules with 14 or 11 cores, and vice versa.
3. LED Bead Temperature. After lighting up for a period of time, touch the LED beads. Those that are very hot, even burning to the touch, are definitely less stable than those with lower temperatures.
4. Solder Joint Quality. Full solder joints indicate good soldering workmanship, and high brightness indicates good soldering; severe solder joints indicate poor contact, leading to troublesome maintenance later.
5. LED Transparent Screen Lamp Mounting Method: Currently, there are two manufacturing methods for LED transparent screens: front-emitting and side-emitting. While side-emitting LEDs have higher transmittance, the LED bead packaging technology still needs market testing. Front-emitting LEDs use traditional LED display beads, which have been proven in the market to be of stable quality.
6. PCB board thickness. If the PCB board for positive light emission is too thick, it will affect the transparency of the LED transparent screen.
