LED display has experienced a steady period - period of development - high tide - trough - five process maturity , first-tier cities in which to install the LED display is also more advanced , and now the installation of the LED display major second and third tier cities to develop second and third tier cities will be the main growth in the LED display .It is understood , LED display is divided into raw materials , technology, installation of three , in addition to raw materials, process and installation costs are also three percent each . At present the main raw material chip , the technology has been greatly improved , can be applied to the mid-market . But in the process and installation aspects need to do more work. Process is the important part, including design and technology , if the process is not good, the LED display mounted in the first half , it will lot of problems, so the current key LED display is installed , but the key is installed welding degrees. As the domestic first-tier cities , although the installation of a lot of the LED display, but the market is not yet saturated , and the secondary cities and three cities are still preliminary penetration, therefore , the future of the domestic LED display market is still much room . The future with the introduction of industry standards , as well as corporate concern for the quality of products , the market will be more high-quality , high-definition LED display , and gradually replace the original sale and the product has been installed , therefore, high-end LED display will be a better future .Display by millions, tens of millions of light coupled together , to guarantee 100% accuracy is very difficult. Welding requires the installation of a number of professional talents , in order to ensure its smoothness and tightness . It is understood that the country does not have a certificate installed LED display installation business . Partly because the whole story which is very difficult to apply the qualification relates to safety, security certification. From this analysis we can see that the development of second and third tier cities in the market , is the main direction of LED products in 2012 due to the impact of the economic crisis in Europe , LED full color display growth not achieved the desired results, in 2014 the town became this year's major modernization proposal force for growth .
