A long way to go? LED backlight to become mainstream need time

Although LED backlight has long been of concern, but let the majority of users with LED display device is still far away. DisplaySearch survey data released in July 30th this year, although the recent rapid growth of the LED backlight market, however, LED backlight to become the mainstream market specifications (market share of more than 50%) may wait until the year of 2015.

Although most display manufacturers have not been transferred to the center of the LED backlight products, but also have the corresponding product layout. Recently, LG released a variety of LED backlight products, has begun to LED backlight products as the focus of future promotion.

Cost is still the biggest problem

2008, the price of LED has been a substantial decline. LEDinside survey data show that the current high power LED, luminous efficiency more than 80lm/W in the second quarter of 2009 the price of products is generally flat or slightly down about 5%, the price range of $~2 $1.5; while 60lm/W~70lm/W products supply more than a quarter decline of about 10%, the current price of about $0.8 in the range of $~1.2.

However, although the price has dropped a lot compared to 2008, but for the monitor, the use of LED backlight will increase the cost. Depending on the quality of display requirements, a liquid crystal display requires dozens of LED as a backlight, cost about $30~60, while the cost of using CCFL is about $10. Since most of the cost of the display comes from the LCD panel, the company's profit margins have been less than $100, so the cost of a few dozen dollars to enhance the impact of the display is great. Therefore, Samsung and other manufacturers are also actively developing lower cost side LED backlight module. In addition, for LED backlight products also need to re design the mold, which also affected the promotion efforts.

Increase the relative impact of small, and thus spread faster. According to DisplaySearch data, in 2009 the LED backlight will become the mainstream specifications of notebook computers.

Product promotion is getting better and better

Although still facing cost pressures, but the major manufacturers to launch the rhythm of LED products is accelerating. In July this year, LG launched the second half of the new monitor. Among them, its new flagship product line W86 on the use of white LED backlight design, while its professional graphics display W2420R is using a RGB tricolor LED backlight. The use of LED backlight to the LGW86 series monitors bring new life. Due to the thickness of the LED backlight is less than the traditional CCFL backlight products, LGW86 series body thickness of only 19mm, 1/3 for general products. The slimmer figure also gives W86 more free space for the design. The stent design is unique, like a red wine goblet body, like a drop of dark red wine.

LED backlight also has the advantages of performance. LG the launch of the W86 series of the dynamic contrast ratio is 200000: 1, the power consumption is very low for nearly half of the ordinary display; using RGB three color LED backlight W2420R color gamut performance, up to 135% of NTSC, with the 30bitS-IPS panel, can show more excellent picture.

Previously, Samsung, AOC, ViewSonic has also introduced the use of LED backlight display products, but often as an image of the product, the actual sales focus is not on it. The LG launched a one-time 3 series of different products, its determination to enter the LED market is evident.
