08 years of using white LED optimistic about 4 applications

2008 LED in the backlight and lighting the development of most manufacturers optimistic, especially will gradually increase in the application of NB LED backlight proportion, the size of the product in the digital photo frame, vehicle navigation and other products demand will have a significant growth in the size of the product, application of LED backlight cost by CCFL is quite close, in the application of small size mobile phone backlight, the number is still the mainstream white LED application, Taiwan manufacturers are also actively toward the field development. In addition, the application of LED in the development of lighting is also quite fast, especially in public facilities lighting, such as street lamps, etc., the Chinese mainland government is also actively introducing LED street lighting settings, expect to reduce energy consumption.

For white NB LED

The price trend in the first quarter of 2008 White LED, in NB applications, although the 2007 panel manufacturers into the LED backlight module is used in the NB positive attitude, but from the beginning of the second half shipments continued to increase, but NB uses LED as the backlight still belongs to the initial stage, the customer for life and brightness, LED patent issues are still considerable consideration, so the sources of supply is only limited to LED ToyodaGosei and Nichia two Japanese manufacturers, so the price remains the same with the previous season. NB is expected in 2008 the proportion of LED backlight sources will gradually increase, the demand for white light LED NB will continue to grow, so the NB will continue to show the situation with white LED in short supply, the price will also maintain a stable situation.

Mobile phone backlight for white LED

In mobile phone backlight applications, because the previous Japanese seems to fade manufacturers in the market, so the Taiwan manufacturers cut actively, and gains, but with Japanese manufacturers continued to back out of capacity, get back in the market, and the first quarter of 2008 mobile phone market coincides with the off-season, demand was significantly weakened, so the first quarter prices showed considerable decline. Taiwan manufacturers are expected to compete with Japanese manufacturers in 2008, the phone backlight with white LED prices will continue to fall.

Digital photo frame with white LED

Digital photo frame in size, because the cost is considered the most important manufacturers, so in the white LED package using TopView, and the thickness of the requirements is not as strict as mobile phone backlight. Because of the use of Topview packaging, in brightness and life performance is better than Sideview, and TopView packaging material cost is low, the yield is higher, so that the overall cost can be reduced. Digital photo frame in the brightness of the design because the manufacturers are not consistent with each other, so the number of LED from 12 to 27, the end of the brightness and cost requirements. While the supply of LED is not limited to Japanese manufacturers, Taiwan and mainland Chinese packaging factory products are used, so in terms of price, compared to the mobile phone and the application of NB is cheaper, the first quarter of 2008 the price of about $0.05 to $0.06, depending on the product in accordance with the actual situation and brightness difference.

Highpower white LED

In Highpower white LED, the current number of Highpower white LED is still small, mainly used in special lighting, such as a flashlight, miner's lamp, bicycle lamp, street lamp, decorative lamp. As for the application in general lighting, especially household indoor lighting, the main lighting manufacturers such as Philips, OSRAM, GE, and Taiwan local lighting industry such as China appliances, no launch LED bulb, so the current market can be found on the LED lighting is still dominated by small factories, white card products, it is expected in 2008 LED used in lighting applications with special lighting, especially in public buildings lighting.

Because currently have the ability to supply Highpower white LED grain manufacturers still limited in PhilipsLumileds, CREE, OSRAM and Taiwan crystal electric, so the first quarter of 2008 Highpower white LED prices remained the same, about $2.
