LED backlight technology faltering market share of less than 5% in 2007

Although with the SONY SZ5, Fujitsu S6410, DELL XPS M1330, etc. have been listed in the LCD screen notebook LED, CCFL backlight TFT screen for the moment, still holds the dominant position of the notebook screen.

Centrino four generation release, is not only the replacement of the mobile platform, is often the notebook technology and product manufacturers, market strategies do great changes in opportunity. In many changes, LED backlight technology wind from the high-end, from the past dotted into a trend of high-end products, but also very impressive changes. However, with the SONY SZ5, Fujitsu S6410, DELL XPS M1330, etc. have been listed in the LCD screen notebook LED, CCFL backlight TFT screen for the moment, still maintained a dominant position in the notebook screen.

LED is still a far cry from the mainstream

LED light-emitting diode Light Emitting Diode abbreviation, is a semiconductor component. The LCD screen with LED as the backlight can have many advantages over the traditional TFT (cold cathode fluorescent tube) (CCFL) as the backlight source. Such as electricity, longer life, more light. Pay attention to the laptop life of the business machine, the use of LED screen has countless benefits. But LED backlit LCD screen price is high, before only applied in SONY TX, ASUS U1F, Fujitsu P7230 and other small size of the aristocracy models. But as the four generation of Centrino models released by LED, the high-end machine screen models is as the spring breeze comes suddenly, in each big brand.

These models are not only a wide range of brands, but also exist in various models. As the business models of the new generation of Centrino four, Fujitsu launched S6410. Its extreme edition uses LED screen, only 6 mm thick. Although the four generation of Centrino platform makes the body weight increased, but rely on LED thin the miracle control in 1.6 kilograms, but less than S6311 using CCFL LCD screen of the previous generation. HP recently released business 2210b/2510p also uses a LED LCD screen. In particular, 2510p, the machine is also controlled at about 1.29 kg. In the small screen business machine. The pursuit of performance models using the LED screen has the SONY SZ5 series and DELL XPS M1330, etc.. The pursuit of thin models are ASUS U3S, SONY TZ series, etc.. It can be said that, at least in the high-end machine, LED has become a force that can not be ignored, as a new trend.

However, although the recent use of LED screen models frequent appearances, but also to see, for a variety of reasons, even the lowest price of the LED models, but also more than 10000 yuan. And more than 12 inches in the ultra portable models. LED distance from five thousand yuan to eight thousand yuan in the mainstream market is still far away.

DELL XPS M1330 is the cheapest notebook LED backlight screen, the price should be more than 10000 yuan.

LED is currently limited to high-end machines and small screen machine market, this situation and some of the limitations of the LED itself is very relevant.

The primary problem is productivity and price. At present, only such as Nichia (Nichia) and CREE (Kerrey) the two companies can achieve the notebook screen standard. There will be a lot of restrictions on production capacity. More important is the price, LED backlight module components of the price of about 2 times the CCFL, the greater the screen size, the higher the cost of using LED backlight technology. And the LCD panel factory did not intend to convert all the production lines LED panel, the cost is difficult to quickly drop. Especially notebook overall prices in recent years, lower manufacturing costs, compression has become the most important compulsory course for notebook manufacturers. In such a fierce market competition under the guidance of the price, to promote the use of LED screen there is the cost of the problem, so only in the high-end models using LED.

Of course, with the expansion of production, the average price of LED is bound to decline, even flat with CCFL, which is not impossible. But this does not mean that we can fully replace the CCFL, because LED and CCFL compared to a number of technical defects. Such as the use of LED backlight screen problems in terms of color saturation, a slight deviation in parts of regional color screen, especially in the local color LCD screen folding deviation is more obvious. In addition, the brightness of the LED backlight is not strong enough, which is much less than that of the cold cathode fluorescent tube CCFL. Also, the LED screen is easy to leak. These technical problems are troubled LED replace CCFL difficult.

According to IDC survey, in 2007 the use of LED screen notebook products occupy the entire notebook product 3%-5%, but is expected by the year 2008, only 7% of the notebook market will be equipped with LED backlight. Despite the obvious rise, but compared to CCFL, or small to the point of humble. Moreover, CCFL is also constantly improved, a variety of screen technology emerging, but also for its long-term existence, long-term support for the mainstream position.
