How to identify the quality of full-color LED display screen beads
What is the most important component of LED display?Is it drive IC, power, or LED bead?Anyone who knows the ropes knows the answer, of course, LED beads. we understand the impact of led lamp beads on the full-color led display, so the purchase of high quality led display with the quality of its lamp beads has a direct relationship . LED WORLD teach you how to identify good or bad from 4 small series?
1.LED chips: the key of LED chips of different quality is life, which is determined by light decay.Low light decay, long life, long life, high price.In general, the larger the chip, the stronger the stability, the higher the brightness, the better the heat dissipation.This is the most important, because the chip directly determines the color index, bright A anti - attenuation degree.
2 look at the packaging process: good quality LED beads uniform color, good gel consistency.Production machinery and equipment is a very key factor, good equipment can ensure the stability and consistency of products in each process, to ensure the product yield.
3. Look at the cleanliness of the surface of LED light belt: if the LED light belt produced by SMT process is adopted, its surface cleanliness is very good, and no impurities and stains can be seen.
4 look at brightness, which is often referred to as how many lumens your lamp bead can achieve, and LM is the unit that measures the brightness of the lamp bead.
