Applications in the mobile phone market, the rapid promotion, over the last 10 high-brightness LED market, the average annual growth rate of 46%.

1, LED industry profile.

1, white LED to become the focus of future growth

As a new lighting technology, LED is the use of semiconductor chips as a light-emitting materials, directly to electrical energy is converted to light-emitting devices. Since the 20th century, the world's first 60 years since the birth of a semiconductor light-emitting diode, LED Lighting Due to long life, energy saving, color-rich, safe and environmentally friendly features, known as the third revolution in human lighting.

(A) upstream: products are mainly divided into single-chip and Lei chip, single-chip system as a substrate material.

(B) the middle: The main products are grain. Carried out according to the different needs of LED chips Lei proliferation, metal deposition, and then the lei-chip mask, etching, heat treatment, electrodes made of grain and finally through the die cutting, testing, inspection complete.

(C) Downstream: grain package. Stuck in the wire frame will die, according to the different product applications, will die package into different LED.

The focus of future growth - white LED. High-brightness white LED products that use the most diversified development and strong growth, its demand for each year show a significant growth (Figure 2), the future mobile phone backlighting, LCD backlighting, general lighting and Vehicle light source the most promising.

2, backlight applications

LED as LCD backlight source, as compared with the conventional backlight technology, in addition to energy-saving advantage, in addition, there are many unique advantages: 1) LED service life can be up to 10 million hours, significantly extending the life of LCD TV ; 2) LED backlight have a better color gamut, good color reproduction; 3) large range of brightness adjustment; 4) LED backlight can be flexible and adjust the light frequency, and the frequency is much higher than CCFL, thus a fine display of motion picture production; 5 ) 3 colors red, green and blue light independently, it is easy to real-time color management; 6) of the backlight can be adjusted white balance, while ensuring that the overall contrast, but without sacrificing brightness and contrast; 7) has a good brightness uniformity, the required auxiliary optical components easier, the screen brightness uniformity even better; 8) power module design is quite simple to use 5 ~ 24V low-voltage power supply, is very safe; 9) LED light source does not produce any radiation, and no mercury The class of toxic substances in green. 10) seismic performance was remarkable.

The data test in August 2007 prior to, with the LED luminous efficiency, brightness increased, with the LED backlight to reduce the number of the current power has been lower than the CCFL backlight. The latest data show that more than CCFL backlight LED backlight notebook notebook low power consumption, 40%, extended battery life 1-1.5 times. As the battery is 500 times the normal charge and discharge times, this time to improve life in disguise also reduced the battery charge and discharge times, which is equivalent to extend battery life.

Thickness in the thickness of the current LED backlight notebook advantage has also been made to 13.3-inch white LED notebook panels, for example, the thickness can be thin 40%, 20% .2 lighter weight can be subject to the downstream impact of marketing strategies notebook makers in 2008 LED universal below the expected, LED in all respects superior to CCFL, but its price is higher than the latter. RGB LED Backlight CCFL backlight notebook panels expensive than the 50-80 U.S. dollars; white LED price less than 25 U.S. dollars higher than the CCFL, but the white LED edge of CCFL will be discounted. Currently on the market have a variety of LED-backlit screen notebook computer, the industry had expected in 2008 will be LED-backlit panels NB in the popular, but because the downstream machine manufacturers in 2008 is still the use of LED applications as high-end models, the price of ordinary The difference is far higher than the notebook to use LED backlighting to increase costs.

Therefore, the downstream notebook sales strategy has a direct impact on LED penetration in notebooks in 2007, about 3% in 2008 was 6% -8%. However, this situation is expected to be changed after 2009. For one, LED backlit becoming more mature and downstream notebook computer makers are already beginning to change marketing strategies.

Notebook manufacturers significant change in sales strategy in 2009, in order to promote the popularization of LED backlight, Dell said its 15-inch LED-backlit LCD screen at maximum brightness situations than the traditional CCFL backlight energy saving 43%. Also announced in the next 12 months, Dell's new line of laptops will be LED-backlit LCD screen facelift. In addition to Business series, Dell expects its notebook shipments worldwide and 80% will be achieved by the end of 2009 comes standard with LED backlighting, 2010 to 100%.

Dell's move shows that the concept of LED is no longer as a model or fashion models, but rather as a standard configuration, its pricing strategy is no longer necessary to take high-end strategy. Dell is one of the leaders within the industry, other companies must follow. Therefore, in 2009 the penetration rate of LED in the notebook is expected to reach 20%. 2007 Global notebook shipments 109 million units in 2008 increased 15% in 2009 increased by 10%, the 140 million notebook shipments in 2009, among which there will be 28 million units the use of LED, pairs of LED demand is 7.03 billion .

LCD TVs and desktop monitors to large-size panel applications LED boost LCD TVs, according to iSupply the end of 2007 statistics, the 2007 LED backlight LCD TV shipments of 100 million units, while in 2007 out of LCD TVs volume is 78 million units, less than 2% penetration rate. As the LED technology advances and costs decline, the next penetration will continue to increase. Displaybank recently forecast that in 2010 the LED LCD TV penetration rate will reach 6.4% in 2011 and 2012 shipments expected to reach 25 million and 5000 million units. We believe that the Displaybank permeability estimates for 2010 are too conservative, we believe that the penetration rate of 9%.

Although the LED display in desktop replacement notebooks require not so pressing, but the LED caused by a more perfect picture quality experience for consumers will be a tremendous temptation, with the LED continue to lower the cost of its penetration must gradually be increased.

2, the world LED market analysis

With unique advantages, LED full color display widely used in sports venues, municipal square, concerts, stations, airports and other places.

Application 2: small size backlight market slows down, the large size will become the new focus.

LED has long been used in mobile phone-based small-size LCD panel backlighting market, continued growth in mobile phone production led to the rapid development of backlighting market. In particular, the emergence of color screen cell phones in 2003 is to promote the rapid development of white LED market. However, with the production of mobile phones to enter a stable phase of growth and technological upgrading led to LCD panels for mobile phones reduce the number of backlight LED to make LED backlighting in mobile phone usage slowdown. Slowdown in volume growth coupled with the continuous decline in average price, eventually leading to the small size backlight market growth sluggish at the same time, the large-sized backlight market has become the new favorite vendor.

Applications 3: Automotive Lamps great market potential, but the short term the market is difficult to start.

LED headlights of a vehicle driven by low power consumption, long life and the corresponding speed characteristics. Statistics show that, in the car driving at 100 kilometers per hour, the vehicle is equipped with LED brake lights are not equipped with LED brake lights than the vehicle braking distance will be reduced by 7 feet. At present, LED has been gradually applied to the third brake light on the car. While the LED is still faced with units of low-wattage lumens, as well as related policies restrictions, taillights and front lights into the car market will take some time, but with the decline in the cost performance ratio as well as the enhancement of luminescence efficiency, LED will gradually realize the ultimate From the vehicle's interior, rear to the front of the transfer, ultimately occupy the entire automotive lamp market. With a huge production capacity car, LED lamp market faces enormous development potential.

Application 4: Interior lighting market gradually started, traffic lights market entry period of steady growth.

Interior LED lighting market is another emerging market. Through the current control, LED can achieve hundreds or even thousands of color change. At this stage, pay attention to the era of personalized, LED color LED decorative lights will help diversify the market's development. LED already made a small decorative lamps, decorative wall applications in hotels, living room. After many years of replacement work, the nation's major cities from the traditional traffic lights replaced with LED traffic lights have been drawing to a close. But with the completion of the work to replace, LED traffic lights, the market will no longer be maintained rapid growth.

Applications 5: Landscape lighting market rapidly.

Landscape lighting market mainly in the streets, squares and other public places decorative lighting the main driving force mainly from the government. By the 2008 Beijing Olympic Games and 2010 Shanghai World Expo impact of Beijing, Shanghai and other organizations to accelerate the pace of landscape lighting, due to LED low power consumption, electricity consumption in the huge landscape lighting market has a strong market competitiveness. At present, LED has been increasingly applied to the landscape lighting markets.

In addition, the Olympics and World Expo will be a major role by far is no longer on its own landscape lighting market led the growth is more important is its role model. Other cities seeing the LED in the landscape lighting in the outstanding performance will be reduced for the LED landscape lighting use concerns, accelerate the use of LE in landscape lighting applications. LED will be from a city of rapidly moving toward the secondary and tertiary urban expansion.

Applications 6: General lighting market road is long, long way to go.

For entry into general lighting market, the power white LED In addition to face, such as light-emitting efficiency is low, cooling is not good, high costs and other issues, will face to the optical, mechanical and electronic control, etc. The integration of LED lighting products common standard-setting . Address these problems requires a long period of time.

As the hotel, business hall, high-grade commercial office and other commercial establishments relative to the price sensitivity of the low. Same time, those high-end places more focus on highlighting grade and distinguished position, for the new products have a greater interest in degrees. These have reduced the LED lighting into the threshold. LED lighting will be the first to enter the commercial market, and gradually to the civilian market expansion.

Fourth, the Chinese LED market manufacturers to analyze the

China's LED industry started in the twentieth century, 70's, late 90's high-brightness LED industry have developed rapidly. 2003 Science and Technology launched the National Semiconductor Lighting Project, while promoting national semiconductor lighting industrial bases in the construction of a total built Dalian Light Industrial Park, Shanghai Zhangjiang Hi-Tech Park, Nanchang Linkage Optical Science and Technology Park, Xiamen Kaiyuan Science and Technology Park, Beijing Yizhuang Economic and Technological Development Zone and Shenzhen Guangming Hi-Tech District, six industrial bases.
