Trend of LED backlight LCD TV next development trend (1)

LCD TV market will be used for LED backlight, is not expected to move forward with the rapid development of. Japan's Techno System Research Xiujie Lin said that if the cumulative TV manufacturers and manufacturers of production plan, "LED TV production in 2010 will reach 73 million 500 thousand units". However, due to the supply of production materials, light guide plate and a resin plate, optical semiconductor and power transformers materials can not keep up, so Lin Xiujie is expected in 2010 the market size is actually 45 million taiwan". Even so, it was more than 10 times the size of the 2009 4 million (Figure 1).

TV manufacturers and panel manufacturers are actively promoting LED backlight LCD TV is due to the global power consumption requirements. Especially in 2011 after the 46 inches above the provisions of large screen TV more stringent. "Energy Star (Energy (Star)" energy-saving electrical products of implementation of the system of the United States and 7 other countries) has developed a very strict standard: 50 inches above the TV regardless of screen size, its power consumption must be reduced to below 108W after 2012 (Figure 2). Xiujie Lin said, "as a response to the provisions of these measures, TV manufacturers and vendors are actively promoting the panel backlight LED".

On the LED backlight LCD TV's next development trend, Lin was held in April 27th, "the seventh TSR seminar," delivered a speech on the 2010. The author will be from (1) LED backlight material supply; (2) the major LCD panel manufacturers strategy; (3) LED backlight LCD panel technology to introduce these three perspectives of the development trend of Lin Xiujie.

Although the chip supply more and more, but the LGP fundamental stock

First of all, the core part of the LED backlight - blue LED (combined with yellow phosphor as a white LED), Lin said, a substantial increase in supply capacity". Especially as the backbone of the OEM supply and the highly anticipated Taiwan LED manufacturers began to expand production capacity, so Lin Xiujie said: "for the panel makers and TV manufacturers, should be a positive factor procurement tends to be stable".

Among the difficulties encountered in the procurement of materials, the more serious problem is the light guide plate. Xiujie Lin pointed out that "the lack of material is the fundamental problem". Light guide plate material - acrylic resin from investment to mass production takes 2 years, so Lin said that in the past nearly 1 years to half a year, there is no hope of rapid expansion of supply". On the other hand, compared with the panel manufacturers in Korea and Japan, LED backlight LCD panel production less Taiwan manufacturers, is actively promoting the backlight LED. Lin Xiujie believes that the end of the third quarter of 2010, almost all TV manufacturers and panel manufacturers will be out of trouble for light guide plate".

It is expected that in Japan, Taiwan and South Korea, the seven large acrylic resin manufacturers, in the past 1 years to half a year and a half of the expansion of the supply capacity of acrylic resin with only one. Large acrylic resin manufacturers to invest in equipment to take the negative attitude of the reason is that although the performance of light guide plate resin requirements are higher than other uses, but lower price. Therefore, Lin believes that this is a fundamental problem".

Worried about the emergence of insufficient supply of material is not only light guide plate and its manufacturing materials acrylic resin. Xiujie Lin pointed out that if nothing is done if things go on like this, "PET reflector (Polyethylene Terephthalate) will also appear insufficient supply".
