The display control system includes input interface circuit, signal control, conversion and digitization processing circuit, output interface circuit, etc. There are many specific technologies involved, among which the key technologies for industry attention and research and development include: serial transmission and Parallel transmission, dynamic scanning and static latching, input interface technology, automatic detection, remote control technology, etc. The communication transmission control of the LED display has communication transmission and video transmission. The video transmission method combines the LED display with the multimedia technology to realize the real-time display of the content on the computer monitor on the LED display screen, as well as the video and television programs. The display screens for playing real-time information are generally used. Video control mode. The specific transmission uses a pair of dedicated long-line transmission interface circuits. In addition, with the development of computer network technology, LED display screens are used more and more in the network environment. In the information display system composed of multimedia and multiple display devices, intelligent network control is adopted, and networked control multi-screen technology is adopted. It is also applied in practice. It is understood that after the export of full-color LED display, the development of LED display industry is booming. According to the statistics of the LED Display Application Branch of China Optical Optoelectronics Industry Association, the total annual sales of LED display application market in China reached 25.3 billion yuan in 2012, which is 15.4 times higher than that in 2011. The development of LED industry is fast and mature, and has a complete industry. The chain supporting system has also accelerated the production momentum. At present, LED display technology at home and abroad continues to innovate, pushing technology to a higher level, such as product core components and key components, and technology has been continuously improved in recent years. The enhancement of core device technology can provide important technical support for LED display products, and also provide the possibility to introduce more product forms. The LED display application product style continues to evolve, and it has brought a qualitative leap to China's LED display technology, which will promote the development of the entire industry towards a benign track! Everyone knows that the export of products and LED displays have entered the international market. They are considered by many domestic companies to be a glorious and proud enterprise. In the past ten years, China's LED display products have shouldered a historic turning point. China's LED display exports to the world for more than 80 exports. Various data show that China's LED display products have entered an international perspective and are accepting global users. Review. However, what should be noticed is that although the export data is large, the number of enterprises and products that can be truly exported under their own brands is much less. What is the reason? China is exploring more needs to improve not only quality, but also product innovation and technological innovation. First, is it an export advantage? It means that the cost advantage is based on the statistics of the LED Display Application Branch of China Optical Optoelectronics Industry Association. Since 2012, the total annual sales of China's LED display application market has reached RMB 25.3 billion, an increase of 15 compared with 2011. The development of the industry has quickly matured and has a complete industrial chain supporting system, which has also accelerated the production momentum. Second, the main competitors are not others. Although China's LED display screens export a lot of independent brands and products to the world, of course, compared with some large foreign companies, it seems that the strength is thin. The main reason is that China tends to focus on counterfeiting, but it ignores innovation and brand R&D and market innovation. Compared with the competition between the United States and Europe, the LED display industry in China is still very good. Third, the development of display technology is new. At present, the LED display technology level at home and abroad is excellent and innovative, and the technology is pushed to a higher level. For example, the core components and key components of LED display screens have been continuously improved in recent years, providing technical progress for LED display. An important technical guarantee. The LED display application product style continues to evolve, and it has also brought overall improvement to the technical level of China's LED display industry. Fourth, the status quo of LED display exports, industry characteristics of enterprises have the advantage of the development of LED display export business, so that domestic display manufacturers have created a good profit rate and overseas reputation. However, analysis from end users and downstream applications, such as: Light Energy Technology, Chau Ming Technology, Ai Biesen, Lian Jian Optoelectronics, Liad, Vietnam, has undertaken more large-scale projects. Especially in the world-famous international competitions and events, this marks that China's LED display can always be unconventional and attract global attention. V. The overseas market is vast, but the challenges are many. Although LED display applications are widely used, there are a wide range of scenes in the world market. According to statistics, during the period of 2010-2014, the global LED full-color display market will maintain a compound growth rate of 30.43. It is expected that the market size will increase to US$9.55 billion in 2014, equivalent to approximately RMB60 billion. According to statistics from an organization, during the period of 2010-2014, the global LED full-color display market will maintain a compound growth rate of 30.43. It is expected that the market size will increase to US$9.55 billion in 2014, equivalent to approximately RMB60 billion. In a market with such a broad prospect, Chinese companies export their own branded products to the world, but they are very thin compared with foreign big companies. The main reason is that China often focuses on counterfeiting, but ignores innovation and brand R&D and market innovation. European, American, Japanese, Korean, and Taiwanese companies all attach great importance to product technology research and development and brand building. In the global display application market, these countries and regions have high brand share, such as Sony in Japan and Samsung in South Korea. Compared with them, our gap is still very big, and the road to go is long. From the global LED display industry market competitiveness pattern and corporate strategic investment research analysis report, we understand that China's LED display companies compete with their peers in the international market. How can we make a bloody way against powerful opponents such as Europe, America, Japan, Korea and Taiwan? What? China's LED electronic display market has broad prospects, but at present, the homogenization of products in domestic cities is very serious, and product technology innovation is not enough, resulting in the emergence of independent brands that do not compete with foreign brands. Domestic enterprises should keep pace with the times, increase product technology research and development, improve product quality, focus on brand building, and strive to cultivate LED display brands with independent intellectual property rights. To develop a high-end international market, it is necessary to deepen brand awareness, strengthen product quality management, and pay attention to changes in the international market, so as to adjust export strategies in a timely manner, in order to be in an invincible position in the ever-changing international market. All in all, in order to have international competitiveness and develop a more high-end, branded international market, China's LED display companies must deepen their brand awareness, strengthen product quality management, and pay attention to changes in the international market, so as to adjust their export strategies in a timely manner. Especially now, the fluctuation of the RMB exchange rate has a certain impact on the company's operations. This and the continued substantial appreciation of the RMB in the future may also bring disadvantages to the company, which will weaken the business results of the company and seriously affect the company's operating performance and profits. In summary, we strengthen our own construction, optimize the internal management structure, improve the production quality of enterprises, and strictly control the brand strategy. I believe that China's LED display companies will go better and further.
