In addition to the single large indoor and outdoor LED display as advertising media, cluster LED display advertising system, the train LED display advertising system has been adopted and is promoting.     (9) performances and gatherings. The large LED display is becoming increasingly common for live video of the public and political purposes, such as our 50th anniversary, all over the world the new millennium celebrations and other major festivals, large-scale LED display in the broadcast live, and advertising, information dissemination played a remarkable role.     (10) Exhibition, LED display one of the essential services provided by the big screen as the organizer of the exhibition content, provide paid services to the exhibitors, abroad, there are some of the larger professional LED large screen rental companies, there are also some of the larger the manufacturer to provide leasing services.     Second, China's LED display industry conditions and market development     1, the state of the industry     After nearly a decade of development, the development of China's LED display industry has begun to take shape, basically forming a batch of backbone enterprises of a certain size. The new century, the optoelectronics industry wide attention, with strength and influence of corporate LED display as a business strategy development, to get involved in the LED display industry, China's accession to the WTO, Beijing's successful bid to become the LED display industry opportunities for development, is expected in the last two years, China's LED display industry will have a greater adjustment and development.     In 1998, the special committee of the lower LED display an incomplete statistics, the year 1998 total sales of more than 10 million yuan, more than 20 companies, its sales totaled about 600 million yuan, the total industry market 85% or more; more than 100 enterprises engaged in LED display, employing nearly 6,000 people in total industry annual sales of 800 million yuan, the previous 1996 and 1997 the growth rate of 40%, in 1998 slightly drop in growth rate of about 30%. Optoelectronic devices Branch of China Optics and Optoelectronics unemployed Association established in 1998 LED display professional committee, focused on a nationally representative and impact of the LED display manufacturers, there are 55 members of the unit was first established, has now grown to 67, basically includes the leading companies of LED display industry.     1999-2000, the LED display professional committee member units of annual output value of more than 1.1 billion yuan, and the degree of sales of more than 1 billion yuan. Compared with 1999, the average growth of the industry-wide production and sales value of more than 10% of individual companies has nearly tripled, there are several enterprises grew by more than 50%, most enterprises steadily, there are a few fell , it is estimated, the output value accounted for more than 75 percent of the national industry. The number of employees nearly 9,000 people, including professional and technical personnel more than 4,000 people, accounting for about 45% full of 2400 people with senior technical titles, accounting for about 28% full of. Most of these personnel engaged in technology development, on the industry as a whole, with a strong development capability.     China's LED display and private industry in the development of the scale, product technology innovation, has maintained a relatively advanced level. The early 1990s, with a maturity of 16 gray-scale 256-color video control technology and wireless remote control and other international advanced level of technology, in recent years, full-color LED display, 256 gray-scale video control technology, Trunked Radio control, multi-level group control technology and other aspects have domestic advanced technology and products to meet international standards; LED display to control the dedicated LSI also has a domestic enterprise development and production and application.     Domestic LED display private manufacturers are mainly concentrated in the east, north, south China region, and large manufacturers market range covering almost the entire domestic market. The number of domestic LED manufacturers also by the increase in the current comparison scale (annual production value of more than 3 million yuan) estimates that more than 150 million of annual output value of more than 20. And because of the relatively high cost of domestic LED display, nearly 100% of market share, similar foreign products market.     2, development of the market     From 93 years so far, the National LED market to sustain growth (Taiwan PIDA estimates, the annual growth rate of domestic display market for about 40%). Photoelectric development of basic industries to promote the LED display to civil industry in recent years of rapid development. According to the statistics of the Electronics Industry Yearbook and a number of professional journals, more than 96 years, the 1997 LED tube production increased by only 700 million over the same period the LED output value increased by 1389 million (domestic LED display that the vast majority of the civil use of the LED is imported. especially the green and blue light), including the LED display output section. In fact, in 1997, 1.389 billion increase in output value in a considerable portion of the LED display to create the output value, therefore, PIDA estimates in Taiwan 99 years mainland China LED display 770 million yuan output value is a conservative figure.     LED display Professional Committee of Statistics estimated 800 million yuan of output value in 1998 as the basis, we hypothesized that the LED display market value in 1996 should be more than 400 million, more than 600 million in actual statistics in 1997, one billion in 1999 more, according to the latest statistical projections, the 2000 National's LED display market value of 14-15 billion. LED display market sales statistics in 2001 about 20 billion yuan, an annual growth rate 1996,1997,1999,2000,2001 annual average of about 40%, only 30 percent in 1998. LED display professional committee member units accounted for 80% of the LED display market sales in 2001, over 1.6 billion.     In the domestic market, nearly 100% of the market share of domestic LED display, similar foreign products basically no market, the main venue of the Forty-third World Championships in Tianjin Sports Center, the Beijing-Kowloon railway, Beijing West Railway Station and Beijing Capital International Airport, Pudong airport, by the domestic behalf of the enterprise successful. Domestic LED display products and the market is growing rapidly, many manufacturers, but the leading backbone enterprise group is being formed, in the era of crowded. With LED display products industry competition gradually become ordered, the market is about to turn into large-scale, brand competition, and gradually formed the strength to occupy the market share of more than 50 percent of three to five business display market will tend to mature.     China's LED display market in recent years the growth rate shown in the figure (unit: million yuan)     China's LED display market in recent years the growth rate shown in the figure (unit: million yuan)     According to the LED display statistics of the Professional Committee, in 2001 the exports of the member units of about 400 million yuan, which is a good sign for the LED display to the international market. Domestic LED display out of the country's accession to the international market will allow the LED industry, the large increase.     LED display development trend     1, high-brightness, color of     Blue and pure green LED products since the since the emergence of cost every year quickly lower and already have a mature business conditions. The full-color LED display will be an important development direction of the LED display. Improve the performance of LED products, full-color display brightness, color, white balance to achieve the desired results, and fully meet the outdoor all-weather environmental conditions, the same time, due to the advantage of full-color display price-performance ratio is expected to the next several years of development, full-color LED display in the outdoor advertising media will increasingly replace the traditional light box, neon, magnetic flap, stadiums will be displayed in full color LED screen mainstream products.     The World According to incomplete statistics, at least 150 manufacturers full color, in which products are complete, the larger the company, about 30, mainly in the United States, Europe, Asia (Japan, China, Taiwan, China). Domestic production of full-color display from the 1994 and 1995 to the end of 2001, a nationwide full-color LED display more than 300 pieces. The wide application of the full color LED display is the LED display industry, the development of a new growth point.     2, standardized     Materials, the technology matures and the market price of the basic balance of standardization and regulation of the LED display will become a new trend in LED display tuxedo. In recent years, the development of the industry, market competition conditions of the traditional products based on price as the primary means of competition, the repeated price down to adjust to meet the basic balance, product quality, and reliability of the system will be the main competitive factors, which standardization and regulation of the LED display With high demand, some industry backbone enterprises has begun implementation of the ISO9000 series standards.     In January 1998, former Ministry of Electronics electronics industry standards promulgated the general specification of the LED display, LED display industry standard chemical work began to regulate. In early 1998, the Chinese Optical Society optoelectronic devices branch of the formal establishment of the LED display professional committee, after the establishment of industry associations, to guide and regulate the industry, to carry out the optoelectronic devices and LED display products and testing standards communication and coordination to actively work in 1999 "LED devices and applications Seminar" held in Kunming, and organized the drafting of the LED display detection method ", modified the organization to discuss, formally issued in August 2000, implement the pilot in the LED display professional committee member units implementation. Electronic Standardization Institute and a professional member of the LED display is the standard system and the specific criteria for the establishment of organizational strength to carry out the work. With the implementation of the system, the formation of product standards and the series of standards, LED display industry in the healthy and orderly development. The formation of industry norms and standards, testing of products with a relatively uniform understanding and judgment in accordance with the development of the unemployed will tend to be orderly.
