LED backlight into a new trend of PC panel

With the gradual deepening of China's energy-saving and welfare projects, LED backlights have become the vanguard of energy-saving and environmental protection, and have become the vane of PC panel fashion trends.
In 2004, Sony officially launched the first LED notebook. After many years, the application of LED backlight in PC panels has become more and more popular. Acer, Toshiba, Sony, Asus, BenQ and Other manufacturers with LED backlights have continuously introduced new products, which further proves that this market trend is not allowed. block.
The current situation of the 11th Five-Year Plan for the establishment of LED product R&D and production base in Shenzhen pointed out that energy conservation has become a basic national policy of China. As the most advanced radio and television technology, LED can be used in mobile phones, LCD backlights, buttons, signal equipment, large display screens, display devices and other fields in addition to the general lighting field.
Recently, "Shenzhen LED Industry Development Plan (2009~2015)" pointed out that by 2015, Shenzhen will build an important demonstration base for China's LED industry technology innovation and an important global LED product research and development production base. It is reported that the Shenzhen Municipal Government will establish a Shenzhen LED product display trading platform in Huaqiangbei Commercial Street, and it is clear that the project will be led by the Futian District Government, and the Shenzhen LED Industry Federation will assist in planning and investment in Huaqiang Group.
The reporter learned from the Shenzhen LED International Purchasing Center that the current LED product R&D and production base has triggered a lot of interest from upstream panel manufacturers. According to a research report published by iSuppli, a market research organization, global LED sales are expected to reach $12.3 billion in 2012. “Once the mass production of upstream component manufacturers reduces the cost of LED screens, it will be fully predictable for major PC manufacturers as downstream applications to obtain high profits.” The industry further revealed that “in addition to netbooks, the most promising potential. Large-size LED notebooks are expected to take over the leading baton."

LED backlight will fully sweep PC applications According to the data of DisplaySearch in the first quarter of 2009, in the LCD market, the penetration rate of LED backlights is expected to reach 37.3% in 2012; in the notebook market, the proportion of LED backlights in 2010 will reach 70%. "In the 16:9 widescreen notebook products, more than 80% of the models belong to LED displays." Li Xin of ASUS Guangzhou Branch told reporters. "The proportion of LED backlight products will rise very fast like the 16:9 display, which is the driving force of the whole industry." Wang Wei, general manager of BenQ Video Products Division, said, "In 2010, the market share of LED-backlit LCD monitors will break through. 20%".
With its low power consumption, slim profile, light weight and environmental protection, LED will occupy the notebook PC display backlight in the next few years. iSuppli predicts that by 2012, every 10 large-size mobile PCLCD panels will have Nine units use LED backlights. iSuppli estimates that 90% of large-size LCD notebook PC panels will use LED backlights in 2012, compared with 4.7% in the fourth quarter of 2007. By the end of this year, the shipment of large-size LCD notebook PC panels using LED backlights will be more than six times that of 2007, from 2.8 million to 17.4 million.
With the application of new panel technology, the improvement of LCD panel cutting technology has led to a decline in the cost of liquid crystal displays. At the same time, people are paying more attention to factors such as entertainment, health and environmental protection. LED backlights have become more and more popular among consumers. Favor. This year, AUO, Chi Mei, Samsung, LG and other upstream panel manufacturers have indicated that they will increase their research and development strength in LED panels for notebooks. Among them, AUO’s goal is to use all notebook panels produced before 2011. LED backlight.
Manufacturers accelerate the introduction of LED backlight products In recent years, major PC manufacturers have entered the LED backlight product market, nothing more than the advantages of fancy LED.
Compared with the traditional CCFL LCD screen, the LED backlight screen has the advantages of lower power consumption, lighter weight, better color expression, etc., just to cater to the consumer's "battery working time is longer, the body is lighter, and the color is more dazzling." "The request."


Nowadays, the trend of LED notebooks becoming mainstream has gradually become clear. Compared with the current general notebook computer using a cold cathode lamp (CCFL) as a backlight, the thickness of the LED panel of the LED backlight is about 1/2 of the thickness of the former; in terms of energy saving, the LED backlight notebook panel It can save about 20% to 30% of power compared to CCFL backlight notebook panels. This year, Sony, ASUS, Acer and other manufacturers have successively launched LED notebooks below 10,000 yuan. The recently listed Sony VAIOCW series notebooks use a widescreen display of LED backlights of 16:9, of which VPCCW18FC is priced at 7649 yuan; VPCCW16EC is priced at 5,999 yuan, and VPCCW15EC is priced at 5,199 yuan.
It is understood that last week, BenQ's first batch of environmentally-friendly LED-backlit LCD monitors have been fully launched. Wang Wei, general manager of BenQ Video Products Division, said: "In the first quarter of next year, we will also introduce LED backlight products with a thickness of no more than 1 cm."
