Modern society, business activities are more and more frequent, each business in order to expand publicity, enhance the company's performance, a variety of marketing methods fancy, which includes the use of outdoor LED display to create momentum. Outdoor LED display screen is widely used in commercial activities today, you know how to judge their strengths and weaknesses? The following LCF editorial to introduce it to you.

LED lamp beads are the key devices that are used in the largest number in the whole LED display, and each square meter will use thousands to tens of thousands of lamp beads. Lamp beads are also the main body to determine the optical display performance of the entire display, directly affecting the audience's evaluation of the display, lamp beads in the overall cost of the LED display accounted for the largest proportion of the overall cost of the LED display, ranging from 30% to 70%, the importance of the importance of it is self-evident.

LED lamp beads is the main determinant of the quality of outdoor LED display, so we are buying outdoor LED display, should focus on judging the advantages and disadvantages of the LED lamp beads to judge a piece of outdoor LED display is good or bad, specifically from the following aspects to do the judgment.

First, look at the brightness, is usually said your lamp beads can reach how many LM (lumens), LM (lumens) is a measure of the brightness of the lamp beads unit.

Second, see whether the light emitting uniform color is consistent, the quality of the good light beads are very uniform, color is consistent. Poor quality lamp beads will appear a lamp bead brightness, a lamp bead dark phenomenon, light-emitting color is not uniform, there will be obvious dark areas.

Third, look at the chip and the chip size, the chip is a good or bad quality of the beads of the determining factors, in general, the larger the chip stability is stronger, the higher the brightness, the better the heat dissipation.

Fourth, look at the glue and phosphor, generally good products will use imported glue, encapsulated lamp beads with a good hand press does not deform, the quality of cheap glue will be deformed or even cracked when pressed and other phenomena.

Fifth, look at the bracket, the general situation of the bracket for the silver-plated red copper bracket, silver-plated red copper bracket is the benefit of fast heat dissipation, you can better heat dissipation to the lamp beads, resistance is small. Some businesses on the market will use ceramic stents to replace the silver-plated red copper stents, ceramic stents thermal conductivity is very good.

Six, look at the encapsulation process, good quality LED light beads uniform color, gel consistency is good. This is inseparable from a good machine and equipment, production machinery and equipment is a very critical factor, good equipment can ensure the stability and consistency of the product in each program, to protect the yield of the product.

The above is a summary of LCF editorial judgment of outdoor LED display advantages and disadvantages, I hope it can help you.
