WitsView:LED backlight design innovation, reduce costs as the primary goal in 2010

LED backlight is the focus of the 2009 display industry, in addition to the application of NB and TV and Monitor products, but also because of the location of light saving properly, grab market beachhead. 2010 LED backlight products will continue to capture the attention of consumers, but it still caused much actual procurement action depends on close to the mainstream market prices appear. LED backlight module design evolution, the cost structure will continue to be optimized.

Compared to the price of the bottom of the CCFL backlight module, the price of the LED Monitor backlight module is still the biggest source of resistance to its promotion. WitsView said that in order to reduce costs as the goal, the new design will start with the lights and LED collocation. First of all, manufacturers try to replace the current mainstream 5630 low-power LED low-power specifications, because the luminous efficiency is better, in the same flux, can significantly reduce the number of LED use. In the light of new architecture, changed to the short side of unilateral light, compared to the current long side of the unilateral or bilateral light design, besides the lamp itself for the length of price, shorter distance to the LED in the number of cut at the same time, can effectively avoid light bright and dark uneven (Hot Spot). The problem occurred. In 21.5W, for example, the new design has the opportunity to import LED and CCFL backlight module spreads, reduced from the current $10 to $6.

In order to maintain the uniformity of brightness, LED TV backlight module in the use of the LED has been the main cause of its high cost. Benefit from the continued ascension to the light guide plate and the LED luminous efficiency, the 2010 LED TV backlight will be four lamps of bilateral light design, to replace the original six lights, four side light structure, save the cost of 1/3 light source directly. WitsView analyst Qiu Yubin said that the light source accounted for more than 50% of the cost of LED TV backlight module, so that the design of the breakthrough will be expected to bring nearly 20% of the cost of the backlight module. In addition to the Korean leadership, the Taiwan panel factory since 1Q10 will also be the same design principle of TV panel production.

Based on the above design trends, the future of the brand customers will be able to obtain lower cost, more competitive LED panel for LED TV or LED Montior marketing, but also has a positive incentive.
