Korea Demand Factory Backlight Led Chips Into Mass Production

2009 10 28 ~ 30, Yokohama exhibition center in the Pacific held a "FPDInternational2009" and "GreenDevice2009" show.

Two exhibitions of common application of this show

LED Chip products, is LCD TV With LED backlight and LED lighting.

South Korean companies use to actively promote the development of LED backlight LCD TV's thin, this in South Korea

Samsung Electronics booth exhibited by the edge emitting type LED backlight 3.9mm thick "world's thinnest" (the company) 40-inch panels.

In the United States, using LED backlight LCD TV has become the market, Samsung Electronics currently holds about 90% of the global LED backlight LCD TV market share.

Held during the same period "FPDInternational2009Forum" seminar, Samsung Electronics TaeSeokJang (development team

LCD Sector vice president of solution components) forecast, LED backlight LCD TV market in the future to achieve leaps and bounds, reaching 3.7 million units in 2009, 3,000 million units in 2010, 2011, the level of 6,800 million units, accounting for the LCD TV market about 40%. The 2007 projections suggest that such TV in 2011, accounted for 10% of the market.

Thin LCD TV with the trend of development, LED backlight begun to be fully implemented, sales gradually. Currently, LED backlight light source in order to reduce the use of the number of LED chips, the edge emitting type of use is on the increase, but there is the type of local dimming (LocalDimming) difficult questions.

In addition, the realization of thin backlight light guide must be used. Its role is to one end of the LED light with evenly distributed throughout the backlight. That is, to reduce the number of LED chips that need to add light guide components.

The transition to the epicentral Difficult because of local dimming, light guide is expensive, so relevant to predict: "LED configuration on the screen just below the direct type backlight in the future will become mainstream." Direct type, while not conducive to thin, but as mentioned above can achieve the same local dimming to enhance

LCD panel Display image quality. And without the use of more expensive light guide and microlens.

To the premise of a direct type of transition is the LED chip slashed prices. The reason why the edge of the widespread adoption of LED type, the original is because a direct type requires a lot of LED chips. If the LED chip production to move beyond the past, the chip unit price down, then, with the use of the edge emitting type light guide compared to the use of multi-block proliferation of boards is more conducive to lower prices direct type.

LED chip's low price dynamic has become increasingly obvious. According to South Korean liquid crystal in the field of university professors in the forecast, "Samsung Electronics has started buying MOCVD equipment, the number may be 200 or more." In response, Samsung has not yet revealed details of the number of insiders, but did not deny that mass production of LED chips will turn into: "on the MOCVD equipment, we are to enable the device to adjust staffing in semiconductor technology, in order to meet the 2 to 3 years after market needs to prepare. "

In addition, in February 2009, the United States Veeco Precision Instruments (VeecoInstruments) disclosed to the

LG Innotek supply of high-brightness LED manufacturers with the decision of MOCVD equipment. About to purchase the number of South Korean liquid crystal in the field of university professor said: "It may be 100 or more."

Taiwanese manufacturers, the AU Optronics (AUOptronics, AUO) for the company's electronic LED manufacturer Lunda
