The expansion of the application of LED display industry to take off

According to statistics China optics Optoelectronics Industry Association Branch LED display, LED display industry in China last year, total sales of about 4 billion yuan. On the market, China's accession to the WTO as well as the 2008 Olympic Games in Beijing and Shanghai, held in 2010, the LED display has brought enormous business opportunities for the. At the same time, LED display in outdoor advertising, sports, transportation and other areas of the market will be significantly increased. In addition, the development of semiconductor lighting, LED display industry will also enhance the overall formation of new opportunities for development. June 1st to 3, the national LED display technology application and industrial development seminar fully display, with the application of the field continues to expand, the development of LED display industry is moving across the new heights.

LED display large enterprises increased

Due to the low requirements of capital, equipment, LED display business scale is generally not too large. Since entering in 2000, China's LED display industry has been in a fairly rapid pace of steady development, the scale of the enterprise also began to increase. According to LED display branch secretary Lu Jiahe introduction, at present, relevant enterprises registered in the association of the more than and 150, the last one or two years, the sales income in the million or billion yuan of above 7: Huizhou DESAY Photoelectric Technology Co. Ltd., Shanghai Sansi Technology Development Co., Xi'an Polytron Technologies Inc, Limited by Share Ltd, Nanjing pine slope in Beijing leyard Electronic Technology Co., Ltd. and Nanjing Henderson Electronics Co., Ltd. and Shenzhen BOE Intelligent Display Technology Co., last year the 7 sales revenue of nearly 1 billion 100 million yuan. "Last year, we on the part of enterprises in the industry sales revenue was investigated from 110 enterprises of the feedback of sales revenues, in 10 million yuan or more than 80, 20 more than in 2004, the sales income of 50 million yuan or more than 16, the sales revenue of 16 for 1 billion 734 million yuan. In other words, accounting for 6% of the total number of enterprises in the industry, its sales revenue accounted for the entire industry, accounting for 15% of the total number of enterprises in the industry, its sales revenue accounted for the entire industry of 52%. Description of China's LED display industry is gradually to large-scale development, in the beginning of maturity." Lu Jiahe said.

Export growth to accelerate R & D investment

In 2005 exports of LED display industry is 551 million yuan, the general manager of Beijing four intelligent transportation system integration Co. company Jizhen forecasts, industry exports will grow by 15% this year.

"To really improve our competitiveness of LED display industry in the global industry, the need for hard work and improved from the following aspects: first, strengthen the propaganda, expand the influence, improve the image, improve the social awareness; second, improve the level of product technology, creating a new connotation in Chinese manufacturing; third, foster the formation of representative enterprises with strong comprehensive strength and scale." Guan Jizhen stressed.

In recent years, Shanghai think twice, Xi'an pine and other enterprises by increasing R & D investment development faster. Shanghai Sansi Technology Development Co. Ltd. General Manager Cheng Deshi introduced in an Chinese electronic newspaper reporter, 2005 Shanghai Sansi completed second relocation expansion, and built a LED display system with a full set of production line.

In the early 90s of last century, our display manufacturers only concerned about the luminous intensity of LED, the perspective of these most basic technical indicators. Today we are more concerned about the attenuation curve, the InGaN-LED intensity under different working conditions of LED ESD (MM or HM), the uniformity of light intensity, wavelength uniformity, angle uniformity, attenuation uniformity, even on pipe pressure drop and reverse leakage current and other technical indicators. But, unfortunately, at present, the vast majority of LED manufacturers are not exactly given these indicators, even LED manufacturing industry will not have some important indicators in the industry standard, the standard or not specified in the test method. This is a way to protect the backward, to some extent hindered the development of the whole industry to a higher level." Cheng Deshi stressed. He further said that last year, think twice about LED full-color display system brightness uniformity correction technology has made progress, the realization of the brightness point by point correction.

LED display industry's technological innovation ability is very strong. However, the current LED display to the size of the enterprise and the enterprise's overall strength, the level of innovation subject at present, enterprises lack of LED basic theory and establish based on the LED display system, to guide the application of weak development.

The general manager of TCL industrial electronics division LED product project department chief engineer Hong Zhen emphasized in an China electronic newspaper interview: "we of LED display technology research and development view is basic research combining with practice, pay attention to short-term and long-term development, the combination of research, the effective resource distribution. Rational use of the application. The enterprise should pay attention to the scientific research and development mechanism, the strong enterprise strength, and the sustainable vision of the enterprise innovation and development strategy."

New applications make LED display bright future

LED display industry is an emerging sunshine industry, as the main body of the display of LED devices, in recent years, the country is focusing on increasing investment. With the increasing development of the western region and the 2008 Beijing Olympic Games, 2010 Shanghai World Expo and other major international events, the application of LED display will also be more and more widely, the next few years will have more rapid development and greater growth.

At present, intelligent transportation is a major city, mega cities such as Beijing, Shanghai and other cities in the main traffic blocking the well-being of the project. According to introduction,
