In 2011, China's LED outdoor electronic display advertising market reached 1.215 billion yuan, an increase of 35.5% over the previous year. According to statistics, the size of this advertising market is expected to reach 1.55 billion yuan, an increase of 27.6%. In recent years, driven by the country's policy support for downstream application demand, the domestic LED industry has developed rapidly, forming a relatively complete LED industry chain system, and the industry has set off a construction boom. The application field of the product industry is gradually expanding. In the field of traffic safety, the application of LED display screens is becoming more and more popular, and it is fully serving as an assistant for intelligent transportation.
Industry Development: Industry Chain Layout and Market Development
LED display as the main force in the field of security monitoring and display, the market development directly affects the direction of the security industry. Outdoor LED is an incomparable advantage in the development of intelligent transportation in the LED industry. It is an important development direction in the LED field. With the unprecedented prosperity of LED technology, LED display products have attracted much attention, widely used in commercial advertising, live broadcast, traffic guidance, stage interpretation and other fields. Up to now, LED display has shown some of its characteristics:
1. The overall development of the industry has reached the scale of scale
The main products of China's LED display industry not only occupy an absolute market in the mainland, but also occupy a certain share in the global market, forming a stable export. The overall quality and reliability of the products have been significantly improved. The mainland LED display application enterprises have performed well in major projects and key projects, and their capabilities in the international market competition and large-scale display system engineering have been significantly improved.
2. The industry's technological progress is obvious, and technological innovation has played an active role in leading and promoting the development of the industry.
The overall technical level of the LED display application industry is basically synchronized with the international development. In the past two years, innovative products have been continuously introduced, the technological innovation in the industry is active, and the product technology development capability is continuously strengthened. Technology development, technical support and technical assurance capabilities to meet specific application needs have been enhanced, and key technologies and mainstream products have matured.
3. The development of industry is standardized and intensive
The LED Display Industry Association has been actively promoting product technology exchange and standardization work for many years. It has effectively promoted the standardized development of industrial technology products through product technology standards and product technology testing. Standardization and standardization have promoted the improvement of industrialization level, and the accumulation effect of industrial layout has been reflected. For example, Shenzhen has concentrated more large-scale enterprises. In recent years, an important feature of the development of China's LED display application industry is the significant increase in the number of large-scale enterprises, the decline in the number of medium-sized enterprises, and the increase in the number of small-scale enterprises. The industry has generally changed from the “olive shape†to the “dumbbell shapeâ€.
4. The development of LED upstream industry has obvious promotion effect on the development of display application industry.
The LED industry chain achieves positive interaction between upstream and downstream, new products and new technologies are rapidly applied and applied. Based on the development of LED chip materials, driver ICs, and control technologies, many enterprises in the industry are in LED integrated applications, semiconductor lighting, lighting and lighting projects. And other aspects have formed a certain technical foundation and production engineering basis. On the basis of traditional LED large-screen display technology and products, the share of LED display products in the industrial market has increased year by year.
5. The major activities have a significant effect on the development of the industry.
In the industrial growth in 2008 and 2009, the driving factors of major events such as the Beijing Olympic Games, the 60th anniversary of the National Day, and the Shanghai World Expo cannot be ignored. On the one hand, we must have a rational understanding on the one hand, and on the other hand, we should take this as an opportunity to seriously sum up experience, actively promote technological innovation achievements, and expand new markets in order to maintain the sustainable development of the industry.
6. The industrial structure is constantly improving and rationalizing in the adjustment
The specialized division of labor in the industry is becoming more and more obvious, and the industrial chain of LED display application products has basically taken shape, laying a good foundation for the continuous upgrading of the industry. At the same time of competition, the division of labor and cooperation in specialized production, technology development, engineering services and other aspects have been reflected in the industry. Market segmentation and outstanding core competitiveness have become new concerns of many enterprises.
Smart application: traffic-induced display helps intelligent traffic
The production and application of LED display screens include semiconductor optoelectronic device technology, electronic circuit technology, integrated circuit technology, information image processing and transmission technology, computer network communication technology, and technologies related to electronic product manufacturing and electronic product installation engineering. LED display screens of different types and different performances have large differences in material composition, manufacturing process and control technology, and the technical connotations are obviously different. Even for products of the same type and performance, the technologies used by different manufacturers are also very large. different. Traffic-induced information outdoor LED display, according to the requirements of road traffic management and the actual situation of traffic guidance information release display, has the following characteristics in specific use functions:
1, high brightness, reasonable perspective
The release of road traffic guidance information is mainly for driving vehicles on the road. The viewing angle of the display screen is not high, and it is generally about ±35° on urban roads. The traffic-induced outdoor LED display works continuously for 24 hours. In the case of direct sunlight on the surface of the display, the display should be clearly visible and therefore require a higher brightness. Under normal circumstances, the visual distance requirement is about 200m.
2, the display color is mainly red, green and yellow
The release of traffic information is mainly for vehicles in dynamic driving. The travel time of vehicles in the visible distance is very short. Therefore, complicated multi-gray graphics and animation content should be avoided. The display content is mostly text and simple. Graphic logo. Considering the common colors of traffic sign signals, red, green and yellow display screens are usually used. Red, green, and yellow colors can display prohibitions, indications, and warnings, respectively.
