LED LCD TV in the popularity of this road impassability?

There is no doubt that the Dolby Laboratory of high dynamic range (HDR) LCD TV technology, with LED backlight, with unparalleled quality. However, consumers need to spend how much money can afford such a LCD TV? This is not yet clear.

"These products have been clamoring to enter the mass market," said EricHaruki, director of IDC's television market and technology research. But unless the LED manufacturers to achieve sufficient economies of scale to reduce the cost of LED, or at a price that is still only indulge in wishful thinking. "

InsightMedia's president, ChrisChinnock, points out that despite the widespread interest in the LED backlight unit (BLU), the cost is 2 to 2.5 times the value of cold cathode fluorescent (CCFL) BLU, which is commonly used in LCD tvs.

He said that the recent exhibition of the Dolby lab HDR technology using Dolby/Sim2 LCD TV may be more expensive. For the cost of using HDR LCD TV, Dolby imaging technology product director BharathRajagopalan do not want to do any evaluation, but claimed that HDR technology can be perfect upgrade, different prices have different performance.

IDC's Haruki believes that it is precisely because of the ambiguity of the concept of scalability, cost problems still exist. Manufacturers never quantify how many LED LCD TVs need to achieve cost and performance balance.

The industry did not volunteer to estimate the cost of the SIM2 LCD TV prototype with HDR technology.

"It's too hard to answer," said Chinnock, of InsightMedia, and it's too early to predict the cost of the product. Whether it is performance, LED number or target price, etc., need to make too many compromises. Dolby/SIM2 LCD TV technology is undoubtedly too expensive, but also in line with the requirements of the target customers who are eager to enjoy the latest technology Sim2. "

LED vendors do not dwell on cost issues. PhilipsLumileds's business management director, WillemSillevis-Smitt, acknowledges that the success of the LED backlit LCD TV depends on the cost. He said the cost refers to the total cost of the LED and the drive IC used to control the various blocks of the LED backlight screen. However, LED suppliers have reason to hope for the future of LED backlit LCD TV, because at present in the field of notebook LCD screen has emerged from the CCFL to LED transition trend. Sillevis-Smitt said: the industry generally believe that in the next two to three years, with LED backlit LCD screen laptop ratio will rise from today's 10% to $50%. "

NXPSemiconductors is planning to further use notebook LCD technology.

The notebook computer LCD screen is not backlit LED, but through the screen display device arranged on the | side of the LED from the side light. NXPSemiconductors engineers hope to move the program to LCD tv.

NXPSemiconductors marketing and business development director JacquesleBerre said that this program can make the flat screen thickness of less than 25mm". And because it uses less LED, it costs less. However, the method also has some limitations. At present, it can only be used from 2430 inch LCD TV is relatively small, and the combination of 2D dimming and new video algorithm, large screen LCD TV LED backlight type scheme can be applied to the 3246.

LeBerre summed up the four decisions LED backlight LCD TV program is a universal promotion of the necessary factors: cost, energy saving, quality and thickness.

PhilipsLumileds to SONY for its 2003 launch of the industry's first LED backlit LCD TV Qualia LED.

Although SONY shortly after the release of this product will be delisted, which did not dispel the desire of consumer electronics companies to pursue LED backlight LCD tv. Envisioneering group research director RichardDoherty said that Samsung and SHARP have entered this field, and SONY and LG Electronics will also be able to join soon.

PhilipsLumileds's Sillevis-Smitt said: "in fact, each TV manufacturers are busy with this product, all manufacturers have a laboratory development model. "

Sillevis-Smitt believes that to reduce the cost of this product, the most important factor is the efficiency of LED.

He pointed out that committed to improving efficiency, is the industry in order to display backlight technology to white LED rather than a new trend of RGBLED. In the display backlight technology using white LED provides a more simple and stable and reliable program, and reduce the number of LED.

Many of the new laptop LCD screen LED are already using white LED. The Dolby/SIM2 prototype is also white LED. Sillevis-Smitt said that in 2003, when SONY launched Qualia LCD TV, the product uses 450 LED, power consumption of 450W. And four years later, we have been able to achieve the same quality of the same LED 120, but the power consumption is only 130W, only Qualia of 1/3.

Vizio factor

Envisioneering's Doherty said: "at present, backlit LCD TV is a very small market, but the share accounted for only 5% - 10% of the market accounted for 50% - 60% may be inherent in the future two years the LCD TV market profits. This is because the traditional LCD TV prices will fall to the lowest point, the source of loss. In contrast, LED backlight LCD TV will get high profits. "

There is also a "Vizio" factor

ISuppli research shows that many people in the consumer electronics industry are surprised to find that a few years
