Compared with CCFL, LED as the backlight has the advantages of thin, environmental protection, energy saving, etc., but the cost is the biggest disadvantage, the proportion of the 2007 laptops with LED backlight is expected to be lower than 8%, mainly due tois that the competing demands of other applications, the high intensity led lamp must be screened, how to melt do not meet the requirements of LED backlight module would be most needed to address the issue; want lower prices in the TFT-LCD plant with the backlight module to reduce costs, while the LED manufacturers in the gross profit margin of other applications better circumstances, whether the large number of suppliers are also key.
11.3 inch and 12.1-inch LED-backlit laptop notebook vendors only introduced in 2006, due to the small number of 12.1 inches laptop, turn LED backlighting as a high-end models, a limited number of demand; 2007 Apple, ASUS, DELL and other computer manufacturers will continue to launch 13.3-inch and even larger 15.4-inch led high bay lighting products, but still positioned as a high-end models, there is no willingness to volume shipments. Product positioning of the computer makers for using the LED backlight module is not changed, will not be much help for the LED industry.
In the field of LCD TV, LED backlight module cost is too high, almost more than three times that of the same size CCFL backlight module, LED-backlit high intensity led lamp is also more than 30% of the price of the same size models. Environmental consciousness needs to be enforced.
