LED backlight LCD TV is set off a quiet revolution

The TFT-LCD panel backlight is a quiet revolution, especially in the importance of LCD TV picture quality (LCD TV), estimated this year LED backlight technology TV panel the proportion of only 3%, but next year will surge to 10%. Market research agency DisplaySearch LED pointed out that this will cause obvious shortage trend, and to control the degree of LED sources, will be the major test panel factory, and may even cause industry reshuffle effect.

Due to the trend of energy saving and thin panel, the panel of LED backlight source has the trend of exceeding the cold cathode lamp tube (CCFL), especially the LCD TV panel. Analysts pointed out that a LCD TV panel depends on the size of the different number of backlight LED uses about 200 to about 500, but because of thinning, the past LED'direct type "(direct light type) backlight, gradually turned into a side light type (side lig ht type), there will be 4 a light (light bars) by a panel of 4, plus the brightness demand is gradually appeared two LED package together, which means that each piece of TV panel LED dosage, may be doubled, become 400 to 1000 stars, suddenly jumped out of the demand. Will cause huge pressure on the supply of material suppliers.

Vice president of DisplaySearch Greater China Hsieh pointed out that currently take LED backlight technology most panel factory positive than South Korea's Samsung Electronics, LCD TV and even special will use the LED backlight technology, called LED TV, which emphasizes the characteristics of high quality. However, the current use of LED backlight TV panel, the gap between the cost of the traditional CCFL lamp is still between 40% to 50%, so many consumers are still waiting to see the manufacturer after the price cuts.

But even so, the potential power of LED backlight has been overlooked, according to the survey, the third quarter of this year, NB panel shipments, LED backlight shipments will exceed CCFL backlight, LED market share of up to 53%. LCD TV, estimated in 2009 the year LED backlight panel applications in LCD TV shipments will reach 4 million 300 thousand, of which there are 68% side light type, while the next is a straight down type. As for the small pen electricity, is currently almost one hundred percent using LED backlight.

Samsung is currently in a joint venture with SEMCO, held in the half way up the Samsung LED company, has long been heavily foreign signed a supply contract, which includes a number of LED companies in Taiwan, to ensure the delivery quantity and cost price. LGD is a strategic investment, holding 30% stake in Woori group's Woori LED company.

As for Taiwan's panel double tiger AUO and CMO, AUO anterior epitaxial plant by their own investment package is lextar featuring kaiding and Wellypower etc. responsible for investment.

The CMO there's LED epitaxial plant Qili photoelectric, the first workshop will have 46 MOCVD (metal organic chemical vapor deposition) machine, foreign investment strategy is bright round, holding approximately 20%.
