Chinese and foreign LED LCD TV performance competition Hisense leading

This year, LED LCD TV began to enter the vision of ordinary consumers, as a new type of high-end flat-panel TV technology, it has advantages of brilliant color, energy saving and environmental protection, and other prominent ultra-thin fashion, LED firmly attracted the attention of consumers. At present, the domestic brands only with independent LED technology, Hisense has launched a batch of 42 inch and 57 inch two products, SONY, Samsung, SHARP from the beginning of May this year, the promotion of 40 inch and 55 inch LED LCD TV products in the China market focus. In the face of this new tablet products, consumers how to choose, what is the best Chinese and foreign LED products?

The day before the Ministry of digital TV standards compliance testing center for specialized market kingpin LED LCD TV for a "key performance indicators thoroughly test", which is the authority of the State Department the first public test of LED products. Take the test with TV products LED Hisense, Samsung and SHARP brand, market sales accounted for more than 50% models, test index for color gamut coverage, power consumption, dynamic contrast and luminance uniformity of 5 key indicators. The sampling completely objective reflection of the current Chinese market performance of LED TV products.

According to the test results, the reporter saw two very important information, one is to raise a lot of key performance indicators LED LCD TV LCD TV is compared with ordinary CCFL, product upgrading is obviously; two, as the only representative of domestic brands, 5 key performance indexes of Hisense LED LCD TV, Samsung is better than all SHARP and other foreign brands. In the depth of the domestic and foreign brands of high-end tablet technology, the domestic brand victory.

The test results on the LED LCD TV, China digital TV standards compliance testing center engineer Sun Qifeng made further analysis: Hisense 47 inch LED dynamic contrast, color gamut coverage and energy efficiency index is the highest, Hisense 42 inch LED color gamut coverage and energy efficiency index is the best. Hisense 47 inch LED LCD TV dynamic contrast to 40000:1, brightness of 445 cd/m2, color gamut coverage of, the average power of 139W, energy efficiency index of 2.04, are the best indicators of product products. Samsung, SHARP's 46 inch, 52 Inch, inch LED products in these 5 key indicators are inferior to the Hisense LED. Hisense LED performance indicators in the outstanding performance, objectively reflect the Hisense LED technology has reached the international advanced level.

LED LCD TV using light-emitting diodes as a backlight source, which makes the principle of the LCD TV compared with the existing, thinner, wider color gamut coverage, more dynamic contrast. More importantly, its operating power consumption can be reduced by an average of 40%, standby power consumption of only 0.5 degrees a year, equivalent to only about $20 fen.

Through the test data to see, LED LCD TV than ordinary CCFL LCD TV has a qualitative improvement. LED color gamut coverage of 105%-113% is far more than the ordinary LCD TV 75%-100% level, so the more colorful; average operating power consumption of LED decreased by 40%, the dynamic contrast is more than 25000:1, and do not contain mercury and other harmful metals, energy saving and long service life. From a technical point of view, LED TV represents a major trend in the future of the tablet industry upgrade.

Deputy general manager of Hisense electric company Dr. Liu Weidong made a keynote speech, "the main innovation technology of the Hisense LED in the control area and the distribution of the dynamic backlight, dynamic test algorithm of video processing, at present, Hisense has completed the development of the key technology of the backlight, and application at home and abroad nearly 40 patents, the vast majority of inventions patent", Liu Boshi introduced.

It is understood that Hisense from 2007 to assume the breakthrough task LED LCD module technology of the key project of the National 863 plan, 2008 Hisense officially put into operation by the Chinese first LED LCD module production line, the first to launch 42 inch LED LCD tv. Dr. Liu Weidong introduced the latest research and development in the field of Hisense LED: Hisense 42, 47 inch LCD TV has been mass market, the 26 inch, 32 inch, 37 Inch LED has also been successfully developed, will be listed in the second half of this year".

Ministry of industry and Information Technology Department of quality division Ma min pointed out: we are very encouraging enterprises through technological innovation, product innovation to enhance the overall competitiveness of products. LED is a big industry is in the rising stage, can create great social power, only such a point is very impressive, LED such relatively ordinary flat-panel TV is reduced by 40%, in the long run, LED industry will have a very good market prospects".
