LED backlight for LCD inject new vitality shipments geometric growth

Was due to the rapid display of notebook computer is used more and more, and have a great potential in the field of LCD panel, light emitting diode (LED) has become a hot topic in TFTLCD market. According to market research firm DisplaySearch, in 2012 there will be 34 billion LED for TFTLCD backlight, panel size from 1 inches to more than 70 inches, more than in 2008 when the growth of more than 8 billion of the above 300%.

2008 LED total shipments is 70 billion 800 million. There are two types of LED for display applications. One is the active outdoor display, using 11 billion LED in 2008, accounting for the overall shipments of 15%. One is the LCD backlight, consuming 8 billion LED, accounting for 11% of total shipments. In the LCD backlight applications, the five main applications of the LED: small and medium display, notebook computers, desktop monitors, industrial applications, especially television.

LED outdoor display and backlight due to the rapid development of DisplaySearch forecast 2012 global LED market unit shipments will reach 167 billion, and display LED, including 24 billion for active outdoor display and 34 billion for LCD backlight LED, in which it will be accounted for 34.7%, is the largest market area. Low current LED will be the mainstream for large size LCD backlight, because this kind of LCD backlight for the cost, thermal management and lighting efficiency have higher requirements. The high power LED drive current higher than 350mA (higher than 1W), due to the presence of heating problems, does not apply to the LCD backlight, will be mainly used for the general application of high brightness lighting applications.

2012 for large size (10 inches above) LED backlight TFTLCD shipments will be more than 368 million, 25 times in 2008. For the LCD backlight design, using the side light LED can achieve slim, so in the medium / small sized LCD in the back of the dominant. Large size (10 inches or more) LCD backlight is usually the use of top light LED, along with the increasing penetration of LED backlight in the laptop and TV market, the top light LED shipments to 2010 will exceed the side light LED.

2009, LED backlight in the notebook computer penetration rate will reach 52%, DisplaySearch forecast, 2010 will quickly rise to 81%. In the LCD TV market, 2009 LED backlight shipments will reach 3 million 600 thousand, the penetration rate is 3%, by 2010 will be raised to 15 million and 10%. Including Samsung, Fei Pu, SHARP, SONY, Toshiba, Vizio and LG, including the main LCD TV brands, are planning to increase the use of LED backlight from the second half of 2009. The main factor driving this change is the LED backlight structure from direct to edgELight type, which reduces the cost difference between the LED backlight and CCFL backlight. Finally, it is expected that in 2012 desktop LED display backlight shipments are expected to reach 31 million.

Witnessed a growing demand for the LED panel, panel manufacturers almost all of them through the construction of new LED, or invest in now the manufacturers to participate in the LED business. The DisplaySearch report showed that Nichia and ToyotaGosei will continue to dominate the blue and white backlight for LCD LED market in the next three years, because the two companies have a strong patent portfolio and customer relationship. However, Samsung LED, Stanley, CITIZEN, ShowaDenko, SeoulSemiconductor and OSRAM are eyeing the LCD TV LED backlight growth opportunities. Finally, Lite-On, Chi-MeiLighting, Lighthouse and Everlight and other Taiwan manufacturers are entering the backlight market through low-cost strategy.

The report also revealed that 2009 operating income for the LED outdoor display will exceed $1 billion, in 2012 is expected to grow to $1 billion 500 million. LED outdoor display in the 2008 Beijing Olympic Games to be adopted, providing its international visibility, in the next few years, such events will become the main factor driving the growth of LED outdoor display.

"Because LED has lower power consumption, to meet the requirements of environmental protection, improve the ability of Dimming, improve the color performance, and can make the LCD panel and the application becomes thinner and lighter, LED will create new growth for the TFTLCD industry, vice president of DisplaySearch's element and research group leader YoshioTamura said. On the other hand, TFTLCD also offers new vitality for the LED industry, because they open wide application fields for the field, also need higher quality and advanced technology. "

Tamura concluded: "this kind of interaction between the LCD and the LED industry, can be regarded as the key to the development of electronic industry in the next few decades. "
