LED large-size backlight is driven by TV brand customers. The penetration rate is expected to reach 50% in 2011. It is estimated that 2012 will be the peak of LED large-size backlight application. Then the market growth will gradually slow down and LED lighting will be used. Performance, LED manufacturers said that with the US LED leading manufacturer Cree take the lead in price reduction, the high-power LED price has been reduced by 10~15% since the fourth quarter of 2010, driving Taiwanese LED chip manufacturers to follow up the price reduction, LED lighting is expected The market is expected to break out in the third quarter ahead of schedule. At present, the efficiency of LED components has exceeded 150 lm/W, reaching the basic threshold of 100 lm/W. LED experts pointed out that Cree, the leading manufacturer, has launched 160 lm/W products at the end of 2010, but the price is relatively high, and the estimated unit price is about US$3. Orsam also launched 136 lm/W products at the end of 2010, and Niigata, Jingdian, and Yuanyuan will mass produce large-size high-power LEDs with luminous efficiencies of 100~133 lm/W in the first quarter of 2011. As the LED manufacturer Philips hopes to reduce the cost to 400 lumens per dollar in 2011, it is expected that the competition in the high-power LED lighting market will heat up in 2011. In addition, the semiconductor leader TSMC tried to use the silicon substrate to enter the LED field, which is also considered a strong rival. Although the current production schedule of TSMC LED chips will be postponed to the second quarter, TSMC has invested in LED packaging subsidiaries. In 2011, the focus will be on LED indoor lighting, and the cost will be reduced by 30% per year. It is expected that the cost in 2011 will be similar to that of LED packaging plants that generally use aluminum nitride materials. According to Cai, as Cree and LED chips begin to cut prices in the first quarter, it is expected that the LED lighting market will have an early entry into the outbreak in the third quarter. However, whether the LED unit price will continue to decrease in 2011, it is still necessary to observe whether the TV backlight demand is revived, and LED price reduction will be an important driving force for the lighting market to take off. At present, the monthly output of high-power LED is about 4 million. The source of chips includes manufacturers such as Jingdian and Cree. Since the chip accounts for 70% of the total cost, if TSMC's production capacity is expanded, it will be more cost-competitive in the future.
