Low Cost LED Display

"Low Cost" is obviously an attractive word to clients of any product, all over the world. Especially to those clients who are interested in the products "made in China", in fact, it's one of the most important reasons of locking on "importing from China". As one of the manufacturers in China, sometimes we're not sure if we should be proud of that, or feel the shame. We understand very much the sense in common that as one commodity, the "good price" of led display is important, but a responsible supplier should pay great attention to the quality and service as well. In our concept, good price should be always after of the good quality. But as the dark side of fast growing economic, and drived by the desire of "selling more", many manufacturers and suppliers have put the "low price" on the first place. That has been ruining the reputation of "made in China".
There is one old saying that "you get what you pay for". We believe it is the truth to honest suppliers - with a reasonable margin, the final price is determined greatly by the material.
There are great quantity of LEDs adopted for one led display, and that's the major part of all the cost. The mainstream offer of led displays are claimed with "SILAN" LED, but why the price differs so much? Here we will just use some questions to answer this question - do you know how to identify the LED chip brand? do you know how to identify the LED chip size? And do you know how to identify the encapsulation technology of the LED? do you know all the differences? 
In fact, even to the led display manufacturers, it is a very complex work to test the LED quality. Even with the tested result, sometimes we couldn't make sure of the quality level because it may perform difference in practical application. The LED vendors has always several classes LEDs to the led display manufacturers, for the same spec. And it is no doubt the practical performance would be different. And how about the "led encapsulation"? Some the led display manufacturers claim their encapsulated LEDs are very good quality and better than the bought. This saying is not worth trusting at all because led encapsulating requires higher technology than led display processing. The professional led encapsulating companies have more dedicated engineers, more experiences and more invests. As far as we have learnt, there is only one reason for the led display manufacturers to encapsulate the LEDs, that's the lower material cost.
In next knowledge pay, we will shortly introduce the possible problems of the low cost LEDs.
