Expert: 04 years of strong demand for mobile phone LED up to only 5 billion

[news] eNews said Jiang Guozhong telecommunications experts before the mobile phone and PHS will be one of the biggest future application market of LED mobile phone and mobile phone, the popularity of color photography, the number of LED used in the mobile phone is greatly increased, which provides a good opportunity for developing Chinese LED vendors, which in 2004 domestic demand of LED mobile phone 5 billion.

Jiang Guozhong said, LED is a key device used in mobile phone, mobile phone is the main key source (about 6 to 10 SMD LED devices each mobile phone), mobile phone display screen LED backlight (every mobile phone usually use 2 to 6 LED devices, the mobile phone is about to use 2 only to the 8 high brightness side light type white LED), LED (mobile phone camera flash with every mobile phone usually use at least 1 LED devices, and will gradually increase to 3 to 4 LED devices); color can change the mobile phone status indicator. Generally, a common mobile phone or PHS to use about 10 LED devices, and a color screen and camera equipped mobile phone needs to use about 20 LED devices.

In 2004 the global mobile phone sales reached 620 million, accounting for more than 60% mobile phone, mobile phone with a camera accounted for about 40% of the amount of use of LED will reach 7 billion to 8 billion. In 2006, mobile phone sales are expected to reach 760 million, accounting for more than 85% mobile phone, mobile phone with a camera will account for more than 50% of the amount of use of LED will reach 12 billion to 14 billion. 2004, China's domestic mobile phone and PHS production capacity reached 500 million, the potential demand for mobile phone LED devices to reach only 5 billion.

Jiang Guozhong believes that the 3G mobile phone is a new generation of mobile communication system can handle images, music, video information, mobile phone screen display more and more fine, the screen is more and more big, more and more high-definition, therefore, 3G mobile phone has put forward higher requirements for LED backlight. Domestic LED manufacturers in 3G mobile phone LED backlight design, manufacturing will face greater technical challenges. Domestic manufacturers generally produce mobile phone keys with LED and SMD mobile phone status indicator is conventional products, no special requirements on the brightness and so on, the main difficulties of the two products to enter the mobile phone supporting system is the domestic LED manufacturers small scale of production, under great pressure of foreign enterprises in terms of price and cost of manufacture.

Jiang Guozhong pointed out that the mobile phone LED backlight, domestic manufacturers basically is to assemble, test, and LED back side light type high brightness white LED light source used, mainly from foreign LED enterprises procurement, this will undoubtedly form pressure in terms of cost. The back light source of domestic LED manufacturers own production by the side light type white LED devices, its performance is not as good as foreign manufacturers, but also related to patent issues, white LED backlight so mobile phone manufactured by domestic side light chip white LED devices, is difficult to enter the foreign mobile phone enterprises and foreign mobile phone market. Domestic LED enterprises to mass production of mobile phones with white LED products, patent issues will become the main constraints.

It is reported that the current domestic mobile phone main LED supplier of Jiangxi LIAN photoelectric Polytron Technologies Inc and Foshan nationstar optoelectronics Polytron Technologies Inc, Jiang Guozhong is currently the vice general manager of Jiangxi LIAN, Jiangxi LIAN introduced the technology and equipment of South Korea, Japan and other enterprises, with the establishment of the SMD LED device and color LED backlight production line machine hand. Foshan star LCD backlight products have been successfully developed, is being promoted to the market, the state of the mobile phone can be supplied, and the development of mobile phone camera with LED.
