LED TV is expected to reduce the cost of energy saving Era

Under the trend of energy saving and consumption reduction, TV energy saving has become inevitable. After the beginning of CES (American International Consumer Electronics Show), Samsung, SONY, LG, Hisense and other domestic TV companies have shown LED (light emitting diode) TV, new TV in the spring of this year, around the theme of the number of enterprises.

The reporter understands, relative CCFL (cold cathode fluorescent lamp) LED, the high cost of this problem has not been solved, but from the second half of last year, with the increasing number of LED TV, LED chain to reduce costs have been greatly improved, especially this year, manufacturers of collective LED the TV, the TV industry is expected in the near future, entered the LED era.

Relative CCFL energy saving up to 30%

Flat-panel TV power consumption is certainly higher than the TV tube power consumption is much higher, so flat-panel TV consumption is one of the key directions of our research and development. Liu Weidong, deputy general manager of Hisense electric Limited by Share Ltd recently at the third annual meeting of green manufacturing.

Xinyikang statistics show that in 2008 Chinese flat-panel TV sales reached 12 million units, if these products are replaced with LED light source, then according to each machine work 4 hours a day, the annual savings of 2 billion 400 million kwh of electricity.

Reporters learned that, LED light source is not only to achieve a substantial reduction in the thickness and weight of the TV, but also has a higher reliability and stability. In the light of life, different CCFL rated service life (Ban Liang) in 8000 ~ 100000 hours, and LED can reach CCFL about two times. LED TV service life of up to 100 thousand hours. If you press the 5 hours a day, a LED TV can be used for nearly 55 years.

Study on the Ministry of information industry and electronic technology group third senior engineer Liu Quanen told reporters China "electronic newspaper", with the brightness of the screen can actively adjust the brightness of LED, compared to LCD TV energy can reach more than 30%. In the aspect of environmental protection, although the manufacturers have been trying to reduce the mercury content of LCD TV fluorescent tube, but no mercury fluorescent tube will bring some new technical problems, do not see the prospect of achieving. In contrast, LED backlight, the advantage is that it does not contain lead and mercury and other toxic and harmful substances, in line with the green fashion, is a true green light source.

The reporter statistics found that since the second half of 2008, the flat-panel TV manufacturers began to LED TV as a high-end products to promote, such as Samsung, SHARP, SONY, Hisense and other brands have launched new products using LED technology. At the 2009 CES exhibition, whether it is Samsung, SONY, LG and other Japanese companies, or Hisense, Konka, Haier and other Chinese companies have exhibited their own LED tv. The global TV market share of the first Samsung Electronics, not only a variety of LED TV new collective appearance, but also launched the world's thinnest LED TV, showing a strong technical strength.

This year is expected to mass market

By virtue of their superior performance of LED TV, and constantly recognized by consumers of LED TV, LED TV will become a new direction for the future development of television, so whether it is domestic manufacturers or joint venture brands are developing LED products. Experts predict that the LED era will soon come, 2009 is also recognized by DisplaySearch and iSuppli two global market research institutions LED most critical year of popularity.

At present, China's LED industry is the upstream production enterprises are mainly Shenzhen, Shanghai, Jiangxi large blue LIAN, the middle production enterprises are mainly Shenzhen, Hebei Segotep, Hangzhou Chuangyuan quantum, the downstream production enterprises are mainly Xiamen Hualian, Foshan photoelectric. Although the Ministry of science and technology has also been approved in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, the establishment of 5 LED industrial base, but most of them are used for semiconductor lighting.

However, terminal manufacturers are keenly aware of the huge opportunities in the LED market. Some time ago, Hisense announced the establishment of a LED module production line. Since then, Tsinghua Tongfang also said it would raise 2 billion yuan focus on LED. Over the past one or two years, Hisense, Konka launched the LED TV, but the light source is purchased or not mass production of the brand.

Samsung Chinese headquarters color TV product marketing minister Li Mingxu in an "Chinese electronic newspaper" reporter the interview said, LED backlight technology is relatively CCFL, has many advantages of high brightness, low voltage, small power consumption, although the cost is relatively high, but the production after the fall, and will surely have a consumer group. According to its sources, the current cost of LED TV has dropped a lot compared to the previous, 2009 is expected to further decline in the cost, and the cost of ordinary CCFL will further reduce the gap.

Li Mingxu said, in March, just after the end of the Korean Samsung LED TV conference, Samsung has launched a variety of LED TV, the first in the conference of the LED TV including 40 inches, 46 inches, 55 inches of product in size, the model has been identified as the 6000/7000/8000 series, then the TV will soon be in the China market officially unveiled.

Liu Quanen also said that two years ago to get breakthrough in the LCD TV with LED backlight technology, a large number of reduced LED using a number of techniques, the 52 Inch LCD TV panel to LED from the original number of more than 1 thousand dropped to more than and 30, greatly reducing the cost. I believe the LED backlight will be able to be more widely used in LCD TV, LCD TV
