LED application market continues to expand

Light-emitting diode (LED) can be seen everywhere in our daily life is very ordinary, also known. LED has many advantages, such as high efficiency, good light quality, energy saving, long life, and so on. It is mainly used in the field of flat panel display, portable device display, lighting and infrared LED. Compared with the traditional light source, LED light source has the advantages of small volume, light weight, good direction and resistant to all kinds of harsh conditions, advantages in power consumption, life and other aspects of environmental protection are incomparable, enough to make a significant impact on the market of traditional light source. With the increasing application of LED, the importance of LED has been paid more and more attention. Recently held in Taiwan, China, a "Color Your Life" seminar, LED for a variety of possible applications for a wide range of discussion. Research Taiwan area China LED major manufacturers everywhere for Zhuang Shiren long photoelectron billion speech that "indispensable in the daily life of full-color LED light source LCD mobile phone screen, to set up the World Cup soccer tournament venue in the outdoor full color LED large display screen, the application of LED has changed the modern human life in the visual experience. Therefore, we have a full view of the perspective of things, with the improvement of optoelectronic semiconductor LED technology, our quality of life will be more realistic, more beautiful level of the new era." Zhuang Shiren's speech this point out the wide range of LED applications, but also point out the LED business opportunities. LED composed of semiconductor material, is a combination of the electrons and holes of semiconductor light emitting component and emit photons of different spectral frequency. The application of LED in the early stage is limited to the use of monochromatic light, but in recent years, with the improvement of the brightness and luminous efficiency of the full color LED, its application field is gradually expanding. In particular, the development trend of LED lighting applications is more attention. Zhuang Shiren pointed out that because of the traditional fluorescent lamps containing mercury and other heavy metals in the rising awareness of global environmental protection, energy saving, long service life and environmental protection advantages of LED, it is bound to replace the current lighting ideal. Although the luminous efficiency of LED is not more than the general fluorescent lamp, but the white LED used in the special lighting market still has great potential, such as solar LED lamps, portable lighting etc.. Furthermore, with the improvement of chip efficiency and the improvement of phosphor technology, it is predicted that in the next few years, LED will gradually develop from local lighting to the market of general space lighting. Zhuang Shiren for the Shanghai Oriental Pearl TV Tower as an example, he pointed out that the luminous point of the Shanghai Oriental Pearl TV Tower facade of the original used is the traditional light source, a light power is 200 watts. The luminance of the traditional light source will be weakened gradually. So since the beginning of 2005, the TV tower to replace the original LED light source. Compared with the original light source, LED positive light-emitting area expanded five times, the luminous efficiency is also increased by a factor of five, and a light-emitting point power of only 50 watts, a year can save nearly 160 thousand degrees of electricity. Overall, because LED has a red, green and blue primary colors, can be mixed into a variety of colors, compared to the original traditional source of four color more combination of full-color patterns and text. Further, photoelectric semiconductor LED light source technology developed in the process of human efforts in the development of high-quality light source, from different angles of life quickly into the application level, and even biomedical. Capsule endoscopy is one of them. The general endoscope is unable to carry out a complete examination of the small intestine, so it is necessary to use a capsule endoscope with a LED light source and a camera in the case of more precise diagnosis. Application of LED borderless, such as derivatives used in home appliances, automotive products business is to make people look forward to, not to mention the application in panel backlight. Although originally expected in the second half of the notebook computer panel backlight application slightly delayed, but in the next three years, LED market growth in the panel backlight applications is no doubt. The permeability LED stage in the small size backlight panel 3.5 inches has reached 100% this year, in the seven inch LED backlight panel market rapid fermentation, estimated this year's LED share of about 30%. The second half of the increase in the application of LED backlight notebook computer panel, in addition to Japanese manufacturers, Taiwan area notebook computer manufacturers such as quanta, Compal, ASUS will launch the LED backlight notebook computer. LED backlight is expected to grow from 11 inches to 13 inches in the laptop screen will grow from this year's growth rate of 3% to. On the other on the price level of observation, the LED application increased, prices continued to decline. Overall, this year, the average price of mobile phone products fell by 50%, coupled with the slowdown in the growth of the mobile phone market revenue contributed to the decline. The panel backlight and other high-end products, although in short supply, but under the strong leadership of downstream manufacturers, the price also fell by 20%. However, the industry generally believe that, although the rapid fall in the price of LED, but other applications, such as digital cameras, MP3 players and other portable products to increase the application, the estimated LED value will continue to grow this year. According to the statistics of Taiwan area Chinese ITRI IEK, led the 2005 global market size of $5 billion 730 million, slightly compared with 2004 growth of 6%. Due to the recent expansion of the production of light-emitting diode manufacturers in Asia too fast, making the imbalance between supply and demand. However, according to the observation of ITRI IEK, Asia in 2006 the new nation
