Hisense push LED LCD TV behind the scenes: grasp the cost control

Hisense has completely independent research and development of the world's thinnest 42 inch LED LCD TV, caused concern in the industry, in the ordinary LCD TV are not popular, why Hisense will launch LED LCD TV, Hisense's own argument is that the "upgrade" for the drive plate industry, the first to launch "TV competition battle", however, the industry believes that the upstream screen resources are foreign brands negotiate conditions, which reflects the Chinese brand hope the other way, self sovereignty over the whole flat-panel TV cost more.

Tablet competition next battle

A few days ago, Hisense announced that completely independent research and development of the world's thinnest 42 inch LED LCD TV TLM42T08GP batch. Hisense's approach is the declaration of the arrival of the era of China's LED LCD tv".

When the plasma (PDP), liquid crystal (LCD) has become the most popular display products for home users, LED LCD TV is actually a new term in the field of LCD TV frequently. LED is the English abbreviation of LightEmittingDiode, LED application can be divided into two categories: first, LED single tube applications, including backlight LED, infrared LED, etc., in addition to the LED display.

LED uses a light-emitting diode as a backlight source, has more advantages than the ordinary LCD TV, for example, can provide red, green and blue, green, orange, amber, white and other colors, color gamut wider color gamut can reach 105% NTSC, which provides a guarantee for the promotion of color LCD tv. In addition, the LED life is very long, the service life of up to 100 thousand hours, if you press a day to start the calculation of 5 hours, a LED backlight LCD TV can be used for nearly 55 years. In addition, it does not contain mercury, better environmental performance.

In foreign countries, many flat-panel TV manufacturers began ambitious plans to launch LED LCD tv. Not long ago, Samsung took the lead in the release of the country's largest 70 inch LED LCD TV, and earlier, SONY, PHILPS has announced the launch of the use of LED Technology TV products. It can be predicted that LED technology will become a hot topic in the recent flat-panel TV industry.

Hisense says mastering LED Technology

LED backlight LCD TV as an epoch-making products are unanimously optimistic about the industry. According to Displaybank forecasts to 2010, the global LED LCD TV market size accounted for a large proportion of sales will be more than 10%, the total market demand in the next 5 years will reach more than 20 million, LED LCD TV will become the new driving power flat industrial upgrading.

Although LED has obvious advantages, but really can replace or replace the traditional part of the liquid crystal CCFL luminescence is not an easy thing. There are three main reasons, such as cost, technology maturity and transparency.

From the current batch of Hisense launched LED LCD TV market, Hisense should have mastered the technology. The first batch of Hisense LED ultra-thin LCD TV market, Hisense has announced a comprehensive grasp of the adaptive dynamic backlight control, quality improvement and LED backlight lighting unit and other independent core technology, effectively promote the LED backlight technology widely used in LCD TV industry in china.

It is said that Hisense was started in 2005 LED backlight technology development. First encounter a lot of difficulties in seeking LED chip and device support, after more than two years of hard work, finally developed the core technology innovation and related algorithms, and apply for the 10 domestic and foreign patents.

The key lies in the breakthrough of cost and technology maturity. It is reported that, due to the adaptive dynamic backlight control, ultra-thin LCD TV LED TLM42T08GP the launch of Hisense achieved power sharp drop of more than 30%, the minimum to 50 watts, the service life of up to 100 thousand hours, even 10 hours a day, can also be used for more than 20 years.

Hisense also said that the core technology of LED and LCD TV module (LCM) of the independent research and development and production, is conducive to the expansion of upstream and downstream industry chain, enhance the function of LCD TV difference and the quality of products, reduce the cost of LCD TV technology to break the monopoly of foreign companies.

Master cost autonomy

According to Hisense's development plan, the second half of 2008, Hisense will be put into production in China's first large size LED backlight module production line, the first to solve the full popularity of LED LCD TV industry bottlenecks. At the same time, Hisense will use its ability to operate the market, accelerate the process of LED backlight LCD TV industry.

It is understood that in large size LED LCD TV, LED backlight can account for about 40% of the cost of the screen, if the Chinese enterprise first to overcome the difficulties of LED backlight technology, coupled with some technical advantages of the whole circuit, the controllable cost ratio, Chinese brand will have autonomy around the whole flat-panel TV the cost of 60%, with more votes than the CRT era, this is the key to Hisense invested R & D LED tv.
