The lamp bead is the most important component of transparent LED display screen, and is also the most used key device, which directly affects the use effect of Creative LED Display China. Each square metre of transparent screen will use thousands to tens of thousands of beads, and the proportion of beads in the overall cost of LED transparent screen is the largest, ranging from 40% to 70%.

For customers, they all want to buy high-quality transparent LED screens. Using inferior LED beads will not only affect the display effect of transparent screen, but also greatly reduce the life of the screen, and even easily lead to dead lights, large color difference and other issues. So the identification of lamp beads has become a very important link.

So how to distinguish the advantages and disadvantages of transparent Commercial Advertising LED Display lamp beads? Qiangsu Xiaobian answers for you:

First: Look at the bracket, the bracket is silver-plated red-copper bracket in general condition. The advantage of silver-plated red-copper bracket is that it can dissipate heat quickly and give the lamp beads less heat resistance. On the market, some businesses will replace silver-plated red-copper brackets with ceramic brackets. The thermal conductivity of ceramic brackets is excellent.

Second: Look at the brightness, your bulb can reach several LM (lumen), LM (lumen) is the unit of weighing the brightness of the bulb.

Third: to see whether the average color of luminescence can be different, the quality of good beads luminescence is very average, color differences. The light beads with poor quality will show the phenomenon that a light bead is bright and a light bead is dark. The light-emitting colors are not uniform, and there will be obvious dark areas.

Fourth, depending on the size of the chip and chip, the chip is also the decisive factor of the quality of the LED Advertising Panel Manufacturer lamp beads. The greater the stability of the chip, the higher the brightness, the better the heat dissipation. This is the most important because of the chip.

It directly determines the color rendering index, brightness and anti-attenuation level.

Fifth: Look at glue, ordinary good products will use imported glue, encapsulated LED beads will not be deformed by hand, low-quality glue will be deformed or even cracked when pressed.

Sixth: Looking at the packaging process, the poster led display China with good quality have average color and good colloid divergence. This is inseparable from good machinery and equipment, consumer machinery and equipment is a key element, good equipment can ensure the stability and diversity of products in various procedures, to ensure the rate of good products.

Above is a small way to distinguish the advantages and disadvantages of transparent full-color LED display lamp beads. In addition, to choose LED transparent screen manufacturer, we must choose the right track, high-profile industry, strong manufacturers, product quality assurance, have done a lot of cases, to provide integrated services of products and processing plans.
