Every customer wants to buy a high-quality indoor LED display. The use of inferior LED lamp beads not only affects the display effect, but also greatly reduces the life of the display, and even easily causes problems such as dead lights and large color differences. Therefore, higher-quality indoor LED displays will use higher-quality LED lamp beads, so identifying the pros and cons of the lamp beads has become a very important task. Next, the editor will tell you six ways to identify the light and easily solve the pros and cons of the lamp beads.
Take a look at the bracket
Generally, the bracket is a silver-plated red copper bracket. The advantage of the silver-plated red copper bracket is that it can dissipate heat quickly, which can better dissipate heat to the lamp beads and low resistance. Some businesses on the market will use ceramic brackets instead of silver-plated copper brackets. Ceramic brackets have very good thermal conductivity.

Second look at brightness
How many LM (lumens) your lamp beads can reach, LM (lumens) is a unit to measure the brightness of the lamp beads.
Third look at the chip and chip size
The chip is the determining factor for the quality of the lamp beads. Generally, the larger the chip, the stronger the stability, the higher the brightness, and the better the heat dissipation. This is important because the chip directly determines the color rendering index, brightness, and degree of anti-fading.

Four look at glue
Generally good lamp beads will use imported glue. Encapsulated LED lamp beads will not deform when pressed by hand. Low-quality glue will deform or even crack when pressed.

Five look at the packaging process
Good quality LED lamp beads have uniform color and good colloid consistency. This is inseparable from good machinery and equipment. Production machinery and equipment is a key factor. Good equipment can ensure the stability and consistency of the product in various procedures and ensure the product's yield.
Master the above five methods to easily identify the pros and cons of indoor LED display lamp beads, so that you can buy high-quality assured LED display products.
Wear Resistant Steel Plate refers to the special Plate product specially used for large-scale Wear conditions.At present, the commonly used steel plate is in good toughness, plastic ordinary low carbon steel or low alloy steel surface by the method of surfacing welding compound must have high hardness, excellent wear resistance of the thickness of the plank product made of alloy wear-resisting layer.In addition, there are cast wear - resistant steel plate and alloy quenching wear - resistant steel plate.
