LED replace CCFL face cost problems

A substantial increase global LCD module will inevitably lead to increase the yield of LCD backlight. China (including Taiwan), South Korea and Japan manufacturers are facing different market positioning and market demand is changing product strategy. In the face of the traditional CCFL (cold cathode tube), EEFL (external electrode fluorescent lamp), the new technology of FEL plane light source and hope instead, most of the backlight device factory, are betting on LED light emitting diode) on the body.

Compared with the traditional CCFL backlight, LED has good color, energy saving, long service life and low pollution etc.. LED backlight can be more vivid color, color gamut up to 108%. These advantages of LED are attracting more and more manufacturers to develop large size LED backlight.

In LCD backlight seminar held on the day before, many domestic experts are optimistic about the prospects for LED backlight. Agilent is currently working with MITSUBISHI to make a 34 inch LCD TV backlight LED, Samsung and SONY also launched a 40 inch and 46 inch LED backlight LCD tv.

With clear 30 inches above the LCD TV market prospects, the panel factory is actively into the research and development of LED backlight module. In addition to Samsung and SONY, as well as LG.Philips, AUO and CMO's other enterprises. Experts agree that, under the impetus of the TFT plant, LED backlight module is expected to become a new generation of backlight technology. At the same time, the backlight module manufacturers in photoelectric radiant and many LED manufacturers are actively developed, hope to attack this huge market.

Chinese in the mainland, with the requirement of PC, a television receiver, car audio, security products, mobile phone, watches and other communications equipment for the LCD backlight LED backlight is growing, local development and promotion will accelerate. The general manager of Zhenjiang Wenrun Electronics Co., Guo Yuguo believes that due to the use of LCD module products is gradually increasing, the demand of LCD backlight will naturally rise, demand growth will lead to expanding production suppliers.

Shenzhen Diguang Electronics Limited company manager Song Jianhong expected, LED backlight shipments this year will rise to about 20%, and the yield increase of high-end products is large. This is mainly due to the mainland's more than and 300 local suppliers to export based, the majority of mainland suppliers more than 50% of the output of exports to Europe, the United States and Southeast Asia and other places. According to the Xiamen Hualian Electronics Co., Ltd. export manager Zhang Hongmei estimates that only 40% of the mainland production for local demand. Therefore, in order to meet the needs of overseas markets, suppliers will focus on the production of low-end products to high-end products. In addition, suppliers in order to reduce the risk, more and more popular custom orders.

From the earliest application in mobile phone display LED backlight module product trends, the traditional CCFL backlight demand decreased significantly; the use of LCD backlight LED gradually prevailed. LED backlight can provide 130% NTSC levels, while CCFL is only 70%. Color extension makes LCD image more realistic color saturation, and LED can reduce the thickness of the display backlight. For example, in the 18 inch LCD module, using a 4-6mm thick LED backlight can replace the traditional 8-12mm thick CCFL backlight. Coupled with the LED product life cycle is more durable, about 50 thousand hours, but does not contain mercury, very environmentally friendly.

Though, LCD light source in the back of LED applied to large size, the technology still faces the brightness, heat, light distribution and other problems. In addition, the main obstacle to enter large-size LCD backlight is the price. The current 15.1 inch LED backlight price of about $150, more expensive than the traditional CCFL about 5.
