LED display technology and products in China with the continuous improvement of point spacing, stability, gray, brightness and other technical indicators, LED display also shows its unique advantages in more and more fields. Its development time is more than 20 years. At present, China's LED display screen is in a new growth period. In 2010, the market scale is 9.4 billion yuan. By the end of 2015, the domestic and export market scale is expected to reach 32.2 billion yuan. It increased by 23.3% year on year in 2014. And it will exceed 80 billion yuan in 2020. The 10-year compound growth rate is over 21.6%. Among them, the market scale of indoor display screen is expected to reach 36.5 billion yuan by 2020, accounting for about 45% of the total. The compound growth rate from 2012 to 2020 is as high as 34.7%, far higher than the overall growth rate of display screen. As for the ultra-high definition display screen opened in 2013, by 2020, its market scale will be up to 12.4 billion yuan, with a compound growth rate of 77%; it will become a real application new blue ocean market. Driving the overall LED display into a new growth period.

LED display industry has developed rapidly, and formed a new development stage, which is divided into three stages:

1. LED display screen utility model stage

LED display has the characteristics of environmental protection, high brightness, high clarity, high reliability and so on. In the last stage, the LED display market only meets people's needs, but in the LED display products, it fails to meet the requirements and the quality is not up to standard.

2. LED display intelligent control stage

With the continuous progress and development of LED display technology, led, as a semiconductor industry, will also be on this high-speed train, giving full play to its high controllability. From home to office building, from road to tunnel, from car to pedestrian, from indoor to outdoor, LED display system with intelligent control will bring higher level services to human beings. LED display industry will also be from making products to designing products to providing overall solutions.

3. LED display replacement acceptance stage

As the characteristics of LED display products are mainly reflected in high light efficiency (low energy consumption) and long life, this stage is the initial stage of LED display development, so in terms of price, there is a certain comparison in the view of customers. Of course, the customer has a process of acceptance, a transition and acceptance of the customer's usage habits and appearance. Let customers understand the characteristics of LED display products, choose one with the characteristics of power saving and long life. In this way, customers are easy to accept its relatively high price, especially in commercial occasions, and now customers are the second in terms of price, mainly in terms of quality. Therefore, manufacturers are now competing in the quality and price advantage. The display effect of the picture is more demanding. When the refresh rate of the display screen is insufficient, there will be scanning horizontal lines. It is necessary to improve the scanning output technology of the LED display control system, so that the refresh rate of the LED display screen is higher than the shutter speed of the general camera, and eliminate the scanning horizontal lines under the camera shooting.
