With the rise of small-pitch LED displays, their overall display effect is good, and the module spacing is small. They are gradually being used in many fields, such as some exhibition halls, big data analysis platforms, high-end conference rooms, etc. Everyone can't help but have a lot of this product. interest of.
The lamp beads are the most important component of indoor LED display screens, and the most used core device, which directly affects the use of LED display screens. Every square meter indoor LED display uses thousands of LED lamp beads. Taking the indoor small-pitch LED display P1.5625 as an example, there are 409,600 lamp beads used per square meter. Lamp beads account for the largest proportion of the overall cost of indoor LED displays, ranging from 40% to 70%.

One, look at the bracket
In general, the bracket is a silver-plated copper bracket. The advantage of the silver-plated copper bracket is that it dissipates heat quickly, can better dissipate heat to the lamp beads, and has low resistance. Some merchants on the market will use ceramic brackets instead of silver-plated copper brackets, and ceramic brackets have excellent thermal conductivity.
Second, look at the brightness
How many LM (lumens) your lamp beads can reach, LM (lumens) is a unit to measure the brightness of the lamp beads.

Three, look at the chip and chip size
The chip is the decisive 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 the most important, because the chip directly determines the color rendering index, brightness, and anti-attenuation degree.
Fourth, look at the glue
Generally good lamp beads will use imported glue, the packaged LED lamp beads will not be deformed by hand, and the 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 colloidal consistency. This is inseparable from good machinery and equipment. Production machinery and equipment is a very critical factor. Good equipment can ensure the stability and consistency of the product in various procedures and ensure the yield of the product.
