LED lighting and LED display development process

As the world's most watched new generation of light, led its high brightness, low heat, long life, non-toxic, recyclable, etc., was described as the most promising development in the 21st century, the green lighting. China's LED industry started in the 20th century, 70's, after nearly 40 years of development, has been formed in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang 7 National Semiconductor Lighting Project Industrialization Base, products widely used in landscape lighting and the general lighting field, China has become the world's largest producer of electrical lighting and the second largest exporter of electrical lighting.
LED lighting ceremony at the Beijing Olympic Games opening ceremony on the stunning debut, beautiful, magnificent, shocking to the world the impression left, and let people have a new understanding of the LED. China's semiconductor lighting industry is very lucky, in the industrial take-off when the Olympic Games can experience the rare opportunity. For the Olympics to gluttonous banquet, LED industry is undoubtedly one of the major beneficiaries of which, LED at the Olympic venues, landscape lighting, indoor and outdoor full color display, instructions and other aspects of good performance, enhanced community on the future development of semiconductor lighting confidence, some experts believe that LED lighting industry in China in 2010 ushered in a new development before and after the peak, looking forward to the Shanghai World Expo will become another milestone in the semiconductor lighting applications.

However, in the application of technology integration achieved remarkable achievements, and can not cover up between China and the world powers in the upstream core technology gaps. Games in the selected LED devices and lighting the vast majority of packaging enterprises in China manufacturing and production are completed, but still need a lot of power type chips imported from abroad. In the Olympics, a lot of the world's top lighting companies familiar to everyone, but the Chinese national brand of lighting companies are rarely known, have to say is no small regret that China, as the production and consumption of lighting power, the possibility of China's lighting business a new round of revolution in lighting technology and lighting in the place of industrial restructuring is the common face. Hope that China will uphold the "higher, faster, stronger" Olympic spirit, out of Asia to the world, the early realization of semiconductor lighting industry to take off!

LED lighting in the area of ​​the development process

The LED industry has developed in the world for years, then you know how the LED lighting field you enter, the following web editor Laijiang Jiang OFweek LED semiconductor lighting into the history of lighting in the area:

1962 first red light emitting diodes birth, people are constantly developing orange, yellow, green and other color LED, and instructions for a variety of signals, logos, digital display, and gradually developed into a small LED display, etc. . 1991, MOCVD epitaxial growth of the industry's use of quaternary materials, the development of high-brightness light-emitting diode; in 1994, developed the GaN substrate first blue light-emitting diodes; 1997 phosphor excited by blue light, make a first White LED; 2001 ANNUAL made a white UV excitation phosphor LED.

High-brightness light emitting diodes as a light source has gradually into the light and color lighting, decorative lighting, and the formation of industry. As technology continues to break through, continuously improve the luminous efficiency, power LED has industrial, multi-chip white LED power combination is greatly improved. Gradually into the field of LED lighting, such as LED car lights, LED backlight, LED flashlight, LED lamp, LED lighting, LED lights, LED tunnel lamp, LED indoor general lighting.

LED display in China's development history

LED development in China, began in the seventies, industry in the eighties. More than 100 companies nationwide, 95% of manufacturers are engaged in production, packaging, the required die almost all imported from abroad. There are several "five-year plan" of technological innovation, technology research, the key to the introduction of foreign advanced equipment and technology to the production of LED technology has been a step forward in the stride.

The formation of the growth period of 1990. On the one hand, limited by the LED material, LED display is a wide range of applications has not been expanded, on the other hand, the display control technology is basically a communication control, display of the target. In the meantime, LED displays are widely used in foreign countries, the domestic low, the product of red and green color-based, control, communication control, four gray, relatively high product cost single-point grayscale adjustment method.

1990-1995, this stage is the period of rapid development of LED display. Into the nineties, the rapid growth of global information industry, and continue to achieve breakthroughs in all areas of information technology, LED display and control technology in LED materials have also been new results appear. Successful development of blue LED chips, full-color LED display screen to enter the market; computer and microelectronics technology in the video control technology, 16-level grayscale display and 64 gray, gray tone display control technology field, the screen dynamic display greatly increased. This stage, LED display from the initial output value of tens of millions to dozens of very fast development of the company, in China's development, some companies, the annual output value of several hundred million dollars, product applications, including finance, securities, annual output value , sports, airports, railway stations, road traffic, advertising, postal services, telecommunications and many other fields, especially in 1993, more stock in the development of the securities industry, LED display market to grow substantially. In the field of flat panel display products LED displays basic form the mainstream, LED high-tech industry into a new display industry.

OFweek semiconductor lighting network data show that: Since 1995, LED display developed into a steady improvement of the overall industrial structure adjustment and improvement of the period. At the same time, LED display in the same competition, many small and medium enterprises, products, prices, a wider range of applications, product quality, standardization and the formation of a series of new problems arise, the development of the LED display is very relevant departments attention and make the appropriate standards and guidance, the current work in this area is gradually deepened. China's rapid development of LED display industry into the channel, with a certain scale enterprise groups have begun to emerge, the basic form to be considered only LED displays in China
