Long to teach you how to choose science and technology were the most suitable el EL
     EL 2011, el for all its amazing insight into market potential, followed, many el EL brands have mushroomed into the market, including a large number of small workshops, and few of the regular factory. As an emerging el EL cold light source, high-tech products, which makes consumers into confusion: What is a good el EL? Measure of a good standard, where is el EL?
 

Long optical experts said was: Select el EL are the "three criteria", the key depends on material quality, the nature of the manufacturer, after-sales service.
 

First: the quality of the material
You may choose el luminescent films in the encounter such a problem, why the same area of ​​el EL and some sellers to 100 (virtual numbers), but some sellers to 300 (virtual number), can not figure out is right? !
Experts are able to remove your doubts, the first may be: to $ 300 the seller is a fraud, raise prices. The second possibility is: $ 100 for the seller to small workshops, mostly manual, and el EL raw materials are made, use and quality of the product can not be verified, how the product in the end, can be used for many years can only go step by step, low cost, the price naturally low; but to the seller of $ 300 is independently developed el EL manufacturers, mechanized production, raw materials are imported, quality assurance, costs are high, the price of natural also high.
This requires you to purchase before el EL understanding of the manufacturers, choose a good brand reputation, after all, practice makes perfect, priceless good reputation.
 

Second: the nature of manufacturer
See the manufacturer is a small workshop or formal manufacturers, experts recommend that you select the cold light of independent research and development production and sales of el film manufacturers, because manufacturers of quality, technology and services are guaranteed.
 

Third: after-sales service
No after-sales service el EL, just like their elders care of "orphan." Protection service is not shirk the responsibility of each company, consumers can continue to provide good service for many years, uninterrupted for the sake of consumers, this is the manufacturers should do. Relatively small in terms of workshops, independent research and development production and sales el EL vendor services more secure. We were Optoelectronics Technology Co., Ltd is a long completely independent research and development, patent protection of intellectual property rights of national high-tech manufacturers.

Optoelectronic Technology Co., Ltd. is a significant long independent research and development production and sales of el EL manufacturers, and always uphold the "customer is God, Who's the most comfortable consumers money, whoever is tantamount to winning the way to fast track the development of the pass" the idea. Also said: Although the market el EL brand, features more complicated, but if the buyer eyes clear your heart clean, a good grasp of el EL "three standards", to buy roses el EL actually is not difficult.
