LED LCD backlight technology to extend the life cycle of liquid crystal technology

China Electronic Chamber of commerce consumer electronics Survey Office Zhang Shi, Zhou Moran

With the development of flat-panel TV products in the world, the development of flat panel TV is becoming more and more popular, so the technology of the new generation of flat panel TV products is higher. LED backlight TV is regarded as a new generation of LCD TV for the upgrading of products, light texture, bright color, energy saving and other advantages, or will become effective to extend the LCD era vitality, pilot of a new generation of flat-panel TV market of TV products; but due to the impact of OLED TV products of high cost and can not produce the large size and other factors the LED backlight LCD TV has more advantages. In addition, LED LCD TV products because of the particularity of its light-emitting principle, in the standby power and the power consumption of the same size LCD TV products have been significantly reduced, more energy saving. Deputy Secretary General of China electronic chamber length, the famous home appliance expert Lu Renbo said: at present, although LED LCD TV is in the initial stage, but many manufacturing enterprises LED backlight LCD TV production technology has been in Changshu, LED LCD TV will become the backbone of the next generation of mainstream television, directly affect the development of flat-panel TV market in china.

Public enterprises LED backlight LCD TV technology to complete the initial market scale

Since 2003, SONY launched the first LED backlight LCD TV products - Qualia, has aroused strong concern in the manufacture of flat-panel TV field, also inspired numerous flat-panel TV manufacturing enterprises in the LED TV product development enthusiasm. Over the next few years, SHARP, Samsung and other companies are in various exhibitions to promote its LED LCD TV products, but did not achieve mass production, LED LCD TV market has begun to germinate. In July of this year, China's own brand Hisense, launched the first domestic LED backlight LCD TV, becoming the first mass production LED LCD TV products. The launch of Hisense LED LCD TV not only accelerate the flat-panel TV market in China LED LCD TV product scale and commercial situation, more domestic fast LED backlight LCD TV products from the laboratory to the terminal sales process. In driving domestic consumer awareness of LED LCD TV consumption, but also to lay the foundation for the next generation of mainstream LCD TV LCD TV LED.

OLED technology and cost control has become the mainstream of the future there is still a distance

For LED backlight LCD TV or OLED TV products which will become the mainstream of the next generation of TV products, the industry have different views, but throughout the stage of the LED and OLED properties of the product, the two little difference in the imaging effect and product performance; but the difference is in the price of products, the size of hand. In terms of price, due to the recent development of LED backlight LCD TV backlight module rapidly, LED cost is the early development has fallen sharply; while OLED technology is not hindered, using large size panel production required for TV equipment, so the cost of the OLED is still much higher than LED. The relative advantages therefore affected to LED back light module can be small and cost, LED backlight modules more easily flat-panel TV manufacturing enterprises in the application, it also speeds up the LED backlight LCD TV commercialization and marketization. At this stage, OLED is still unable to compete with LED LCD TV, LCD TV can not be replaced by a new generation of mainstream TV products.

LED LCD TV breaking costs hinder the development of LED LCD TV market will accelerate ahead

In addition to the domestic brands in the same party in April fund-raising 2 billion yuan to focus on the construction of the LED project, only Hisense LED backlight LCD TV technology really landed, the product price is relatively high. In spite of the development and upgrading of LED backlight LCD TV technology in recent years, the cost of LED backlight module has been reduced, but still higher than the traditional CCFL (cold cathode fluorescent) backlight module. Home appliance expert Lu Renbo said: the popularity of new technologies generally occur at the cost of 30% times higher than the old products, and with the decline in the magnitude of the accelerated popularity. Although the LED backlight LCD TV is affected by the high cost, but with the improvement of technology and the stability of the supply chain, industry chain, LED backlight module and backlight module between the traditional CCFL of the cost gap will gradually decline, is expected to LED backlight LCD TV market share in late 2010 or early 2011 rising rapidly.
