LED small size backlight: focus on 5 to 10 inches new market

San Francisco] [editor's note: expand the application market is the biggest driving force to promote the development of LED industry, various sizes of LCD with LED backlight, semiconductor lighting, automotive, transportation, municipal, landscape and other fields including lamp LED products a huge potential market. To this end, this newspaper will launch a series of reports on LED applications, today we will focus on the analysis of the small size of the LED backlight market, please pay attention.

In the mobile phone, such as the small size of the strong backlight applications, the LED market in 2001 to 2004 has maintained an alarming growth rate of 46%. Especially in 2004, with the surge in mobile phone and mobile phone screen supply, application of LED backlight on the mobile phone to achieve a leap forward development. LED as a mobile phone and other small size LCD backlight has been very popular, LED has successfully occupied the small size LCD backlight market. But the mobile phone based small size LCD backlight market has been affected by steady growth in mobile phone production and the decline in the amount of single machine, the market growth is weak. The next small size LED backlight market drivers will come from which applications, experts generally believe that, in addition to mobile phones, MP3, MP4, PDA, GPS, car display and other products there is a huge business opportunities.

Mobile phone is still the largest application market

LED light-emitting diode, LED products can be seen everywhere in our life now, roadside billboards, household appliances all kinds of lights and mobile phone keyboard backlighting are using LED as light source. Su Zunhui, deputy general manager of Shenzhen Dili Electronics Co., Ltd. believes that at present, the phone is still the main application areas of LED backlight. In particular, the domestic market, the use of 3G phones, will promote a new round of development of the domestic mobile phone market. 3G mobile phone is a new generation of mobile communication terminal can handle images, music, mobile phone screen display more and more precisely, the screen is more and more big, the definition of increasingly high demand, therefore, 3G mobile phone has put forward higher requirements for LED backlight. 3G mobile phone backlight brightness requirements for LED to achieve more than 8000cd/m2. Therefore, the domestic LED manufacturers in 3G mobile phone LED backlight design, manufacturing will face greater technical challenges and cost pressures.

In addition, with the development of some new display technology, LED backlight market will also cause some impact. Huagang photoelectric (Shanghai) Co., Li Ying said that the mobile phone color makes LED backlight applications on the mobile phone to achieve leap forward development, but after the mobile phone market saturation, mobile phone backlight LED lower threshold, the LED backlight profit is greatly reduced. In addition, some of the new display technologies such as OLED and mature will also have some impact on the small size LED backlight market.

5 to 10 inches is a new market power

Li Ying believes that in 2008, the use of mobile phones outside the portable DVD and car navigation systems using 5 inch -10 inch LCD panel with LED backlight become a new driving force in the market. In 2008, due to the sharp decline in chip prices, the cost of its LED closer to CCFL, coupled with the advantages of environmental protection, so that LED backlight will become the mainstream of small size LCD backlight.

Mobile phone backlight is one of the largest LED application market, because the market is already saturated, prices fell significantly, although sales are on the rise, but sales did not increase significantly. Liang Bingwen, general manager of Shanghai Blaupunkt photoelectric materials company believes that in the mobile phone market, the domestic market share of LED companies is still relatively low. Other small size backlight market has PDA and DVD players, car monitors and MP3, MP4, etc., LED market applications in these areas showing rapid growth, it is noteworthy. Another noteworthy emerging market is the application of mobile phone flash. Camera phones accounted for the rapid increase in the proportion of white light LED light and thin, power saving features make it shine in the application of mobile phone flash. With the development of mobile phone camera, mobile phone flash demand for white LED will be in the next few years rapid growth. "Liang Bingwen thinks.

LED industry chain serious market monopoly

Strategies Unlimited company in November 2007 at the LED related seminars published a high brightness LED market analysis report. Shanghai SVA (Group) the Central Research Institute deputy director Jin Bo said, from the report we can see that the LED market in 2006 of $4 billion 180 million the size of the market, if the small size LED backlight accounted for about 40% market share calculation, small size LED backlight market size of about US $1 billion 670 million.

Like other high-tech areas, LED backlight market technology monopoly and market monopoly is also very obvious. Jin Bo said that at present, the global high-end market by the 5 major manufacturers CREE, Lumileds, Nichia, OSRAM Opto Semiconductors (OSRAM Opto Semiconductors) and Toyoda Gosei (TOYOTA synthesis) control. These 5 companies in the global market share of high brightness LED over 50%. Among them, the United States Cree in the production of SiC based blue LED chip is known, leading the United States Lumileds in high power LED packaging products, Japan is the world's GaN Nichia blue LED and white LED technology leader, OSRAM photoelectric have white LED phosphor patent technology, combined with TOYOTA Japan Nichia like pioneer for GaN blue LED. 5 companies in 2005 market share of more than 50%. It is not difficult to see that the market monopoly is very serious. In the low-end market, China's enterprises in Taiwan low-cost strategy is eroding the market share of japan. Jin Bo said that the Japanese in virtue of the advantages of high brightness blue light and white LED patent technology, the global leader in high brightness LED market. Taiwan in China
