LED display screenIn this era of low-carbon economy, energy conservation and environmental protection, it has developed rapidly, from a single economic industrial chain to today's diversified, independent R & D and production of new industrial models. In this process, LED display has mainly experienced six stages.
　　
1、 Formation stage: before 1990, the application of LED display screen was mainly reflected in indoor application, mainly in indoor LED display screen, instrument display and other fields. At this stage, the development of LED is mainly limited to the limitations of materials, and there are also great constraints in communication control. LED display screen has not been widely developed in the application field, and the effect is very general. Based on the analysis of LED large screen, during this period, LED display screen has been widely used abroad, with a wide range. Due to the constraints of technology, materials and other aspects, Our products are mainly red and green, and the production cost is relatively high.
　　
2、 Popularization stage: in the five years from 1990 to 1995, the domestic LED industry was in a stage of rapid development. After entering the 1990s, the world was in a period of rapid development of information. Communication technology continued to make breakthroughs in various fields. The LED industry also continued to make new achievements in the two major fields of materials and control technology. LED large screen display products became the mainstream at that time. Since the successful development of blue LED chip, full-color LED display screen has also appeared in people's vision. The rapid development of electronic computers has made the dynamic effect of LED display screen geometric multiple. These years are the most rapid growth period of China's LED industry.
　　
3、 Upgrading stage: this stage is from 1995 to 2003. During this period, the application of LED display has entered a very stable upgrading period, and the industrial pattern has been continuously improved, showing a steady upgrading trend as a whole. In addition, the full-color LED display technology has made great progress in all aspects. During this period, the competition is also intensifying, there are many small and medium-sized enterprises in China, and the product prices are also falling, which is undoubtedly a very gratifying thing for consumers. LED display is also further expanded in the application field, and has become the mainstream display product in the market.
　　
4、 Innovation stage: from 2003 to 2007, this is the innovation stage of LED display screen. Domestic major enterprises can be said to be blooming. LED product technology and application fields have developed horizontally, forming a broad market. Where there is a market, there will be competition. The continuous intensification of competition promotes the continuous improvement of led in application, the emergence of new products, and the development of LED in basic materials and related technologies, The innovation level of domestic enterprises has been continuously improved.
　　
5、 Scale stage: from 2008 to now, the application of LED display screen tends to be mature and rapidly develops towards scale. In a series of large-scale sports events, LED products have been widely used, further promoting the large-scale development of the application market and industry. Small and medium-sized enterprises have begun to rectify and merge. Only through integration can they have the capital to compete with large enterprises. Many phenomena in the domestic LED industry show that China's LED industry is developing towards collectivization and scale.
　　
6、 Industry reshuffle stage: from 2011 to now, the influx of a large number of practitioners in the early stage has led to a mixed industry, overcapacity, and industry reshuffle has become a trend. Since 2011, many brand enterprises have closed down one after another. The industry reshuffle has become the mainstream in recent years. Reshuffle is the pain that the LED industry will inevitably experience in the growth, and the industry will move towards healthy and steady development in the era after reshuffle.
