After the era of Bo: domestic LED industry will go to where

2010 Shanghai World Expo left us too many wonderful memories. People have come to the forefront of modern scientific and technological innovation, which makes people remember the deep is the fact that many of the exhibition hall through the visual technology to bring visual feast. At the opening ceremony of the World Expo on 57 meters long, the distance is 6 mm, a total area of 10 thousand square meters of the new super HD semiconductor light emitting diode (LED) screen to become the biggest bright spot in World Expo.

In October 2010 31, which lasted 184 days in Shanghai World Expo officially ended, the hall closed at 22:30, when the park closed in 24. Night 20:10, Shanghai, World Expo closing ceremony began. The closing time is approximately 1 hours, including procedures of ceremonies and theatrical performances, including the lower part of the ceremony of World Expo flag, the flag over other sectors, including performances on both sides of the three big stars and many non professional volunteers. Theatrical performances is the top of the stage by a group of more than 60 thousand, the composition of the LED of 7560 cubic meters of the "star matrix", the end of the performance of the literary and artistic performances on the occasion of the singers sing affectionately "for tomorrow", on the occasion of the end of the performance of the world's top 6. Suddenly, "star matrix" secret, dense, changeable and provides a colorful visual feast for the people.

According to Xinhua News Agency reported that the more than 60 thousand LED lights all by computer precision control, each "light" can be in different positions suspended above the stage, thus demonstrating a variety of shapes. In fact, this is not really a beacon of light suspended in the air, but by the Donghua University, Shanghai, the development of new high-performance fiber rope traction". The rope not only has the advantages of light weight, high elasticity, good flexibility, but also can change color at any time. Therefore, the audience barely visible traction rope, but can only see the 10000 "stars" on the stage on the sky drift.

In addition to the opening and closing ceremonies, many venues have adopted the most advanced LED display the most environmentally friendly, the interpretation of a colorful picture for people. Beijing Pavilion using the LED screen, after the exhibition, the demolition of the exhibition hall has not become a very complicated problem, the staff has been in advance of the various parts of the line by the code, of course, LED big screen is no exception.

The end of in World Expo indicates that the "post Expo era". After the era of Bo, LED industry go from here? LED become the main trend of the development of lighting, which is no doubt. LED low power consumption, long life, non-toxic environmental protection, such as the embodiment of the modern people's pursuit of low-carbon life, these characteristics promote LED into ordinary people's family. LED is widely used in the field of indoor outdoor, automobile, electronics, and so on, and it has a huge market, LED industry is considered to be the pillar industry of our country in the future.

Shanghai World Expo global scale for the first time to use LED as the landscape lighting, LED technology has broken through the brightness and light color adjustment problems, the technology has also been greatly improved. However, the domestic LED enterprises generally small scale, weak technology, poor product quality and other factors to become China's LED development, while market competition has entered a vicious cycle of price war.

LED market in China is mainly concentrated in the packaging and downstream industries, while the power chip and phosphor core technology is still in the hands of foreigners. LED industry chain, the core technology accounted for 2/3 of the profits, and packaging and downstream industry profit of only $1/3. Research and development of China's LED industry has become a major breakthrough in the development of factors.

A good situation in the future market, disorderly investment has also become a major factor impeding market development, and is the most important factor. In the fierce market competition, enterprises need not only technology, but also need a good investment environment and.
