HP LED notebook computer compared with the traditional power panel 20%

In LED backlight module prices continued to decline after the first HP LED notebook computer Compaq 2510p has officially appeared, said that compared with the traditional panel models, the former energy saving about 20%. HP will be launched this year, a number of LED models, is expected to close at the end of the LED notebook computers can be close to the previous market expectations of fifty thousand yuan or so.

Compaq 2510p 12 inch models, Intel Centrino Pro platform, equipped with Intel Core 2 Duo U7600 dual core ultra low voltage processor, 1GB memory and 80GB hard drive, built-in hard disk lock, fingerprint recognition, TPM security chip and other security mechanisms, the Windows Vista Business operating system. NT $59900.

LED laptop in this year officially floating on the table. From the past only Japanese manufacturers such as SONY (Sony), Toshiba (Toshiba), Fujitsu (Fujitsu) launched a price more than seventy thousand yuan NT market situation this year, including ASUS (Asus), HP (HP), DELL (Dell), apple (Apple) launched sixty thousand NT $LED models.

Saving power

The manufacturers see nothing but the advantages of LED: compared to the current general notebook computer using cold cathode fluorescent lamp (CCFL; Cold Cathode Fluorescent Lamp) as the backlight, light poles (LED; Light Emitting body Diode) backlight notebook computer panel with thickness of about 1/2 thickness of the former; energy saving, LED backlight notebook computer panel more than CCFL backlight notebook computer panel to save about 20% to 30% of electricity.

In thin models, due to the limited capacity of the battery, so the use of small power consumption processor, monitor is more important, said Chen Jinghong, vice president and general manager of HP Taiwan personal systems business group.

Because of this, Intel led the extension of battery life working group (Extended Battery Working Group, EBL WG) push LED panel. Foreign reports, EBL WG, chairman of the Intel mobile platform mobile platform to promote the development of business group manager Kamal Shah said the scheme, EBL WG is trying to achieve the notebook computer for a day or more battery life, and display subsystem is the component of notebook computer power consumption is the largest, accounting for system power consumption 60 to 75%, thus reducing the power consumption of the system is an important index to lengthen the time of notebook computer batteries.

Although the LED panel has these advantages, but the cost is too high, the reasons for the notebook computer manufacturers are not large-scale use. Analysis of the mechanism of Taiwan's topology Research Institute also under the revised expectations for LED notebook computer.

"This year is expected to total LED notebook computer market penetration rate of 5%, and in the end of this year, the highest price or about NT $sixty thousand," the extension includes the researcher photoelectric research center Cai Yizhen said. The research institute last year is expected to target penetration of 8%, this year, LED models are expected to decline to about $fifty thousand yuan
