Although the energy-saving LED backlight market is still the three major controversy

Near the National Day golden holiday, the first half is still very calm LED backlight LCD TV market suddenly showed blowout trend.

In late July, Samsung in the Chinese market launched a new three series of 9 new LED TV, at the beginning of August, SKYWORTH, with the first to launch its own LED tv. In addition, foreign brands are also accelerating the speed of innovation, SHARP has been present in the market Chinese launched three LED TV, LED TV series the latest release of this year will be "eleven" before the full sale of SONY; a 40 inch LED TV has also been listed.

August 12th, vice president of the China Chamber of Commerce, said Wang Ning, more energy saving and environmental protection, longer life LED TV, the second half of this year will become the biggest hot plate market. But with the surging tide of household electrical appliance enterprises LED, listed only a few months of LED TV sparked a lot of controversy: what is the real LED TV? LED TV should be thin? LED TV prices are not high?

LED definition dispute

The manufacturers push at the same time, there are some people accused of: LED TV is the concept of speculation, the real LED TV should be the integration of the realization of LED panel and the backlight source, the current market launch LED TV, is the use of LED backlight in LCD panel based on.

For the concept of LED TV dispute, Samsung Corp technical staff in an interview with the times weekly interview, said, in fact, LED TV is the use of LED backlight LCD tv. At present, the market does not exist in the use of LED panel and backlight integrated tv. Of course, to achieve a comprehensive technical upgrading of existing LCD TVs, which is OLED products (organic light-emitting diode), which is the next generation of display technology.

For the development of LED TV, Chinese of Electronic Science and technology group third senior engineer Liu Quanen said that two years ago, a breakthrough in the LCD TV with LED backlight technology, a large number of research on reducing LED using a number of techniques, the 52 Inch LCD TV panels to LED from the original number of more than 1 thousand down to more than and 30, greatly reduced the cost of.

"For the market and consumers, it is important that this new product can bring about the upgrading and change," said Li Mingxu, marketing director of Samsung Electronics China headquarters. From the perspective of the existing market demand, ultra-thin, energy saving, beautiful appearance in line with the future direction of flat-panel TVs, LED TV will get good development space in the market at this stage.

In July this year, issued by the Chinese electronic technology standardization research "LED TV key performance indicators diagnostic test results show that the LED TV coverage rate, power consumption, dynamic contrast and brightness uniformity of several key indicators in the color gamut, than the traditional LCD TV products average level has greatly improved.

"Thin" dispute

At present, the overall trend of electronic products is more and more thin, but in the LED TV, thin to what extent also sparked controversy.

Samsung due to the use of side light LED technology, the thickness of the body to reach the finger thickness of 2.99 cm, the screen size to 40 inches, 46 inches and 55 inches of the main size. Subsequently, SONY showed only 0.99 cm thickness of the ZX1 series LED LCD tv.

For Samsung and SONY's ultra-thin products, domestic color TV manufacturers questioned, saying that LED TV is not as thin as possible. The reason is that, in order to reduce the thickness of the product, so that the light source is too close to the top of the optical film, it is easy to produce uneven light. If only the pursuit of thin products, the consequences are to show the color is not true, LED lost its own advantages.

LED TV thin struggle, in fact, is the LED's technology dispute. Currently, the LED TV has a straight down white LED light source and a side white LED light source, respectively. LED products on the market, Samsung and SONY are side light type; and Hisense to straight down based.

The side of white light can be achieved LED TV, but the technical level of enterprises is very high; and straight type white LED technology advantages in the picture regulation is obvious, but the technology cannot achieve the thin, and the whole system of enterprise design and integrated ability requirements are relatively low, this kind of product in China home appliance enterprises.

"Frivolous" in the end is not important? Appliance industry experts said, consumers care more about electronic products "frivolous" characteristics, because this is obviously to enhance the quality of products, is a brand and corporate R & D capability and manufacturing technology eventually intuitively reflect the appearance of the products, every inch of the decrease of mean technology promotion.

LED price dispute

SHARP 52 inches LED TV to sell $100 thousand, SONY's 40 inch LED TV also sell more than $20 thousand, LED TV price than the same LCD TV on the market expensive 50%. Suning store, a sales person in charge told die Zeit author.

China Electronic Chamber of Commerce Deputy Secretary General Lu Renbo said, LED TV is still in the early popularity, due to the small size of the product, there is a big gap in the production cost compared to traditional LCD tv. On the other hand, we must also see that the performance of LED TV is also higher than the traditional LCD TV quality, in appearance more in line with the trend of fashion.

Samsung Electronics Co., Ltd. Li Mingxu said that with the improvement of the industrial chain, the expansion of production scale, LED TV prices will have room for downward adjustment. In July 10th, held in 2009 (fifth) Digital Industry Development Summit Forum, the experts have been considered Samsung LED TV to create a flat screen TV
