LED jumped to the mainstream size, ASUS N series laptop energy saving

A few years ago, when the LED backlight technology first notebook development breakthrough of energy consumption bottlenecks of the dawn, it was predicted the future it will become a mainstream laptop display application, but from the LED notebook make first appearance so far, in addition to high-end thin products 13 inches or less, there are still uncommon mainstream large size machine make a difference.

But in the global efforts to reduce the cost of all walks of life in winter, ASUS adhering to the concept of quality is still in the rock, the international 3C's calm force, launched its first strike across the 10.2 - 15.4 inch full size models of N series, and is equipped with LED screen backlight for the full range of big, once again let us see the LED jump the mainstream size and even enter the video machine in the field of hope.

Change: more energy saving, more environmentally friendly, more light

LED is a light emitting diode (Light Emitting Diode) referred to as the backlight notebook LCD display, compared with the commonly used CCFL (cold cathode fluorescent tube), can bring more advantages in energy saving, environmental protection, light, screen performance etc.. In the notebook components, display power consumption accounted for more than 30% of the total power consumption of the notebook system, while the use of LED backlight can save about 20% to 30% of the electricity, undoubtedly provides an important support to extend notebook battery life. At the same time, due to the production of raw materials in the LED did not use harmful mercury, but also more environmentally friendly than mercury containing CCFL.

In addition, LED display has a better performance in the video, can provide up to 160 degrees wide angle, and can adapt to 40 degrees below zero temperatures, strong light and take care not to have been wrong, for more light for the mission of the notebook, the high quality material of LED display also contributed to better achieve goals.

All along, LED in household appliances, lamps, anti fog lights and other lighting equipment, there are universal application. Notebook actually has been using LED, like a variety of red, green lights are useful to this diode. In the current wave of global environmental protection and energy conservation, the further use of LED as a laptop LCD backlight, apparently also has more in line with future trends.

In view of the above advantages, LED has become a new area of the notebook industry development. However, due to the LED LCD screen in the beginning only a Japanese company put into production, so pay attention to the light and electricity specialty Japanese machine manufacturers to become the direct beneficiaries, waterside pavilion. Until the beginning of last year, the country's first LED notebook ASUS U1, but then the world's four officially launched LED models notebook manufacturers, but also a unique ASUS is not listed in the legion.

Breakthrough: from 11 inches to 15.4 inches

In fact, LED backlight is not a new technology, before its integration into the notebook, has long been in the mobile phone, PDA and other small electronic display screen size. For the size of the notebook is much larger, the need to increase the cost of using a new backlight, it is the main bottleneck hindering its face. For example, 12.1 inches screen needs to be composed of 36 LED light source, the need for 13.1 inches, 14.1 inches, the need for 48 inches, 15.1 inches will need to be 60, the larger the size of the need to increase the cost of the higher. Thus, from 2005 to 2007, the market can be seen on the LED notebook is only 11 inches from a small extension to a total of 13 inches, the mainstream of high-end lightweight areas outside the machine is still hard to trace.

Half a month ago, ASUS launched the N series, can be described as the above problems have been a breakthrough. This across 10.2 inches to 15.4 inches of fashion environmental models, the whole line using LED backlight LCD screen, bring a lighter body, lower energy consumption, more comfortable visual enjoyment and more healthy application experience. At the same time in the display update, a lot of personalized innovative elements of the application, but also to LOHAS as the theme of the N series was fully demonstrated.

Among them, the main "free" 10.2 inch N10J, a breakthrough into a separate display chip, bring graphics powerful small size rare books; emphasize "pleasure" and 12.1 inch N20, through the built-in LAN-STAR auto speaker system, realize the light machine in the professional level of valuable audiovisual; advertised "wonderful" 14.1 inches to provide N80, create new styles Ryukin, chocolate, blue, silver tassel four collection design, better meet the needs of individual users; advocate the "health" of the 15.4 inch N50, with ASUS's first laptop anion identity for the city people to open the window whenever and wherever possible the breath of nature.

Outlook: 2010 LED models over 50%

No matter what kind of attitude towards the development of the current situation of LED notebook models, at least one point has been the industry consensus: as long as the upstream manufacturers to expand production capacity of LED, LED backlight to replace the mainstream CCFL is an inevitable trend.

ASUS notebook business group leader Chen Zhixiong said, until the future of LED production capacity is large enough, with the spread of the cold cathode tube narrowed to about 10%, notebook LED wave will pop up. Today, with the launch of the Taiwan area manufacturers LED panel low-cost solutions, 10% of the goal is just around the corner. And trends ITRI Industrial Economics Research Center in the Taiwan area and even expected, CCFL and LED backlight module price is expected to reach agreement in 2009, and then predicts the LED backlight notebook computer penetration rate in 2010 will be more than 50%.
