A significant advantage of LED quietly towards our threshold

Perhaps LED for consumers, but also some strange, but it is speeding up into our family. In the near future, LED will not only replace our current lighting devices, but also will replace the current projector bulbs and LCD TV backlight...... LED LED significant advantage, namely the semiconductor light emitting diode. LED backlight source has a long life (100 thousand hours), high color purity and color reproduction characteristics of high rate, high brightness, not afraid of cold, strong adaptability, good reliability, no mercury pollution, will play an important role in the field of liquid crystal display backlight in the future. With the continuous improvement of brightness, LED not only can be made into a variety of lamps, but also will gradually replace the CCFL (cold cathode fluorescent lamp) backlight, the most important LCD backlight. The average life expectancy of CCFL usually in 20 thousand to 50 thousand hours, the average life expectancy of LED can reach more than 100 thousand hours; CCFL starting voltage up to 1600 Volts, voltage after start-up also has 800 V; the turn-on voltage of white LED is only 24 volts, lower voltage after the start, only 12 V; mercury containing CCFL, LED does not contain mercury, which belongs to the green environmental protection product. According to the Daktronics products consultant and Production Director Niu Dudley, made of doped semiconductor materials led by a number of very thin layer, a layer with an excess of electrons, another layer is the lack of electronic form positively charged holes, through the current work, combination of electrons and holes, the excess energy in the form of light radiation is released. Different light emitting diodes can be obtained by using different semiconductor materials. Different from ordinary cathode ray tube (CRT), plasma TV, LCD screen (PDP) (LCD), LED display is the use of semiconductor light emitting diode as a light emitting element of the display, because it has high brightness, bright color, low voltage, low power consumption, long life and other advantages, although the angle of view do less than 180 degrees, the pixel pitch is also not too small (generally not less than 3 mm), but the LED display with its unique advantages in the large screen, especially in light of the indoor and outdoor gradually replace other products, and with the development of technology, will replace the current backlight. According to the statistics China optics Optoelectronics Industry Association LED display applications branch, in 2007 China's LED display market sales reached 7 billion 200 million yuan, the next few years will continue to maintain a high growth rate. I believe that with the LED display technology innovation, as well as the falling cost of people on the LED product awareness continues to deepen, the scope of application of color LED display will be further expanded, and will play a significant role in the development of social economy. The superiority of the enterprises have set foot in the LED has been known for its manufacturers, manufacturers unanimously optimistic about the prospects. So, regardless of lighting companies or home appliance manufacturers have entered the field of LED. Thin now, has become an important trend in the development of flat-panel TVs, and energy consumption, environmental protection and other issues of flat-panel TV is the focus of attention of the consumer. LED applications can easily achieve ultra-thin LCD TV, energy saving and environmental protection. Konka has entered the field of LED. Reporters learned from Konka, Konka LED backlight source design and production line will be the foundation of the city of Jiangsu in Kunshan. Meanwhile, Konka has reached a cooperation agreement with a LED sapphire substrate development team, in order to promote its layout in the upstream industry LED. Konka sources, including the construction of LED display, LED lighting, LCD TV LED backlight, LED application and LED sapphire substrate industry upstream industry in the next 3 to 5 years, so as to form a complete industrial chain of LED, the annual output value and strive to exceed ten billion yuan. This is not a whim konka. For Konka strategic layout in the LED industry, Tang Hongmin, deputy general manager of Konka Research Institute believes that the LED industry is in a growing demand, LED backlight is expected to start in 2009. At present, China's LED production is growing rapidly, but mostly in the supply chain and OEM production mode. In order to build a complete industrial chain, Konka has been specially built a postdoctoral workstation and two R & D team responsible for LED technology research. In fact, as early as 2001, Konka set up a wholly owned subsidiary of Konka video as a Pathfinder to enter the LED industry. At the same time, the rapid development of the LED light source projector, by many industry experts as the projection technology and the future development direction of the most promising, conform to this trend, many brands have launched LED micro projector products. According to reports, the biggest advantage of LED light source projection is the life of the projector LED module life of about 20 thousand hours or more, which greatly reduces the cost of use and maintenance costs. If consumers buy a home projector, watching 2 hours a day on average, then a year is 730 hours, 20 thousand hours can be almost 27 years, even 6 hours a day on average, can also be seen in recent 10 years. This means that a complete solution to the problem of blocking the popularity of the projector - lamp life is low. According to Tsinghua Tongfang, vice president of sun min revealed that high brightness LED lighting project of Tsinghua Tongfang has achieved industrialization, currently has 5 production lines put into production, will add 15 production lines in the first quarter of next year. The problem still exists domestic LED industry each year in more than 30% speed rapid development. In 2007, the output value of LED application products in China has exceeded 30 billion yuan. However, there still exist some problems in the development of LED. Chinese Lighting Association chairman Chen Yansheng said,
