LED LCD TV to break through the cost bottleneck

Recently announced in September will launch its first 40 inch LED (Light Emitting Diode, a light emitting diode) backlight of LCD TV Samsung, SONY in November 2004 to become the market launch of a LED backlight LCD TV. Enterprises in China although there has not been on the market for LED backlight LCD TV, but from the end of last year, Xia Xin, Xoceco, Konka and other mainstream TV manufacturers have introduced a prototype. Not long ago, Qi Ling Technology (Taiwan, China's LCD panel manufacturers CMO subsidiary) also announced that it is stepping up the development of equipped with LED backlight LCD TV, and strive to put into operation in 2007.

LED backlight with the mainstream application of CCFL (Cold Cathode Fluorescent Lamps, cold cathode fluorescent lamp) compared to the obvious advantages, but because of the high cost, has not yet achieved large-scale applications. Current manufacturers will still regard it as the forefront of products. The launch of LED backlight LCD TV manufacturers, in the realization of profit and establish a high-end image of the balance of the latter. Experts said that when the cost of LED backlight source control in the CCFL 1.5 times less than large-scale applications become possible.

LED to enhance the overall quality of liquid crystal

At present, almost all LCD TV backlight are used CCFL, using it as a backlight LCD TV, color saturation is about 75%. The color rendering is generally about 25% lower than LED. At the same time, its brightness will gradually weaken with time, the color will change, the vast majority of CCFL backlight in the use of 2 years to 3 years after the brightness decreased significantly (life in the 15000 hours to 25000 hours). In terms of power consumption, the use of CCFL as a backlight LCD TV is not satisfactory.

It is because of the CCFL backlight with the flawed, many enterprises will have LED backlight LCD TV technology into the idea.

In fact, LED can be seen everywhere in daily life, colorful roadside billboards, household appliances, lights of different colors of mobile phone button backlighting, car headlights, using LED as light source. After the introduction of LED technology LCD TV, LCD TV for the first time in terms of color performance can be compared with CRT.

According to the relevant person in charge of Amoi, using LED as the backlight of LCD TV, will greatly enhance the overall quality of LCD TV, LCD TV color gamut equipment LED backlight can reach 105%, to achieve the color and color subarea CCFL can not match the regulation, so as to achieve a more accurate color reproduction, the LCD TV the color is more rich.

At the same time, by contrast LED backlight LCD TV is higher, the image of the dark to dark, light is brighter, and even can reach the plasma TV's new contrast. In terms of environmental protection, because the LED backlight does not require CCFL backlight source of mercury, very suitable for green environmental requirements. Moreover, the LED backlight LCD TV power smaller, power saving, the service life of up to 100 thousand hours.

But the LED backlight source also has serious congenital defects, which bear the brunt of the high cost. Senior manager of market research company Sheng Zhe told reporters that the current LED backlight module for CCFL of the average price of about 2.5 times.

Manufacturers push LED high-end image for the tree

LED backlight source of high cost, direct performance for the use of this light source LCD TV prices. It is reported that in November 2004, SONY launched the 46 inch LED backlit LCD TV Qualia005, priced at up to about $9565. Samsung's first 40 inches in Europe in September, the price of $3000 LED backlit LCD TV price.

Can be seen from the previous two years, the price of the product can be seen, the current price of LCD TV LED backlight, although high, but the price is not high. And this is closely related to the price of LED backlight module fell sharply over the past two years. Reporters learned in the interview, the first two years, the cost of LED backlight module is about 5 times the CCFL module, has now dropped to about 2.5 times the price level.

Sheng zhe analysts believe that the price level of China's LCD TV market, the general 40 inch LCD TV priced at around $15 thousand. The size of high-end models with the price of about 20 thousand yuan, Samsung's 40 inch LED backlit LCD TV $3000 pricing is not too high. In fact, LED backlight LCD TV can be considered in the application of large high-end models.

Reporters learned that the enterprises of our country although not yet in the market sales of LED backlight LCD TV, but from the end of last year, Xia Xin, Xoceco, Konka and other mainstream TV manufacturers have introduced a prototype.

From SONY, Samsung and China's color TV companies for the attitude of LED backlight LCD TV can be seen, the company launched LED backlight TV products or prototypes, is to enhance the high-end image of the product.

The reasons are as follows: first of all, SONY, the launch of its 46 inch LED backlit LCD TV model is Qualia005, Qualia is the most high-end SONY products sub brand. Followed by Samsung, industry experts generally believe that Samsung's release is based on brand image, rather than profit for the purpose of. Although SONY has launched Qualia005 LCD TV, but because the price is too high, only a handful of sales, if Samsung can meet the EU RoHS environmental protection laws and regulations by using 40 inch LED backlight LCD TV (Samsung 40 inch LED backlit LCD TV first into the European market) and selling point, appropriate propaganda, Samsung is expected to take the high-end models to enhance its brand image, reduce SONY brand gap.

Finally, the domestic manufacturers, although there is no introduction of goods, but the purpose of the prototype is to show that such
