The 40-inch Full HD Backlight LED Side light type, for example, LED components cost-accounting for about 34%, accounting for about 13% of the cost of light guide plate, Zengliang diaphragm into the accounting for about 15%. DisplaySearch said, to make LED backlights cost reduction, we must reduce the LED design, output power, as well as the cost of LED chips. In the first quarter of 40-inch Full HD panels cost price of the LED backlight is about 118 U.S. dollars is estimated in the fourth quarter of this year will come to 100 U.S. dollars, a decline of 15%. The major driving force cost reduction lies in increased production, as well as the LED chip and the decline in raw material costs, coupled with upgraded LED luminous efficiency, so that the amount of reduction in the use of LED chips.
DisplaySearch LED backlight market and technology analyst Kevin Kwak said, in order to reduce the cost of LED backlighting, manufacturers must develop new LED backlight structure, in order to minimize the use of LED chips and make light guide plate design optimization, and to make optical film structure better. In early 2009, 40-inch LED-backlit panel with CCFL Backlight of the cost ratio of about 3.7:1, predicted that by the fourth quarter of 2010 will be reduced to 2.8:1.
