The cost of this year dropped 15% DisplaySearch:LED backlight

Market research firm DisplaySearch pointed out that the LCD LCD panel and TV machine manufacturers continue to strengthen the development of LED (light-emitting diode) backlight board to enhance visual effects, to achieve thin, reduce power

DisplaySearch market research firm pointed out, LCD LCD panel and TV machine manufacturers continue to strengthen the development of LED (light emitting diode) backlight, in order to improve the visual effect, achieve thinning, reduce power consumption and so on, the LED (light emitting diode) backlight cost is quickly decreased. With 40 inch Full LED HD backlight board, for example, the first quarter of this year, the price of the 40 inch Full LED backlight board cost about $118, but is expected to fall to $100 in the fourth quarter of this year, a decline of about 15%.

By the light cost according to LED quarterly report and CCFL DisplaySearc released the latest LED backlight, key to rapid development, it is to reduce costs, as well as with the traditional CCFL (cold cathode tube) backlight spread accelerate reduction. For LED backlight LCD TV core components, including: LED light-emitting diode chip, light guide plate, brightening film, CCFL backlight LCD TV, these elements do not exist in the traditional result, how to reduce the cost of raw materials, reduce the key LED backlight and backlight board CCFL cost.

To 40 inches Full LED side light backlight board, for example, the cost of LED components accounted for about 34% of the cost of light guide plate accounted for about 13%, accounting for about 40% of the brightness of the diaphragm into about 15% of the cost of HD. DisplaySearch said that in order to reduce the cost of LED backlight, we must reduce the cost of LED design, output power and LED chips. In the first quarter of this year, 40 inch Full HD LED backlight cost price of about $118, is expected to be $100 in the fourth quarter of this year, a decline of up to 15%. The main driving force behind the decline in the cost of production increases, as well as the cost of LED chips and raw materials decreased, coupled with the LED luminous efficiency improved, so that the use of LED chip to reduce.

DisplaySearch LED Backlight Market and technology analyst Kevin Kwak said, in order to reduce the cost of LED backlight, LED backlight manufacturer must develop new structure, in order to make use of the LED chip was reduced to a minimum, and the light guide plate design optimization, and the optical thin film structure. In early 2009, the cost of the 40 inch LED backlight board with the CCFL backlight board was about 3.7:1, which is expected to fall to 2.8:1 in the fourth quarter of 2010.
