many people don’t know what to pay attention to in identifying the led electronic display screen, but according to the editorial, many customers have many incorrect operations in the process of purchasing the led display screen. so how can we better avoid these misunderstandings? how can we distinguish a good quality and cheap led screen? next, i will sort out the common misunderstandings of the led screen.
first, you need the best to buy 
first of all, the purchase comes from their own needs, while meeting the needs, there must be some forward thinking. but we can’t blindly pursue the best. although it’s generally better to be expensive, it depends on whether we can symmetrically use it or not. we also need to consider our own economic situation. otherwise, we will only waste more money on functions we don’t need.
ii. national standards, regulations and standards
the general specification for led display screen was issued by the ministry in the 1990s. now it is 2017. looking back at the previous standard, too many changes have taken place. take for example, the runaway point, the national standard is 5/10,000, take the indoor double primary color led display as an example. generally, the display screen with standard resolution of 740480 is 10 square meters and 42465 points per square meter. according to the national standard, there can be 120 out of control points. but no one will buy such led screen in the rapid development of modern life.
3. software is free and inexpensive
there is a common problem in chinese enterprises, that is, only the production does not research and development, the same problem also exists in the current led display industry. at present, only a few led screen companies have their own genuine software, many people may not know that it is illegal to use piracy now. low price is good, but not necessarily what we want, more importantly, cost-effective. the same is true, not necessarily to buy at a low price, which is more difficult to distinguish.
