Energy saving hot LED oversupply phenomenon tends to serious

Such recently once again become a hot topic in LED from the aspect of energy saving is actively energy-saving products. Taking a broad view of the development process of LED, since 2002 LED small size display (mainly used in mobile phones) began to penetrate, peaked in 2005. However, with the improvement of efficiency, the number of LED units used by the unit is gradually reduced. When mobile phone growth tends to saturation, the total demand for LED began to decline. At this point LED began to look for the next application: the size of the display. With the continuous improvement of cost, LED in 2007 in the demand for the size of the display to reach saturation, and the previous small size as LED demand began to fall. LED began to enter another application: laptop monitor, and in the end of 2009 began to enter the TV display applications. With the wide application of LED in large size display, the performance of LED has been raised to more than 100 lumens per watt, and the price is also rapidly declining, this trend for the development of lighting applications in the LED has a great help.

2009 LED TV sales higher than expected, resulting in a rapid rise in demand for LED, while the supply side is too late to keep up with the pace, so there is a shortage of hot conditions. The thermal conditions allow LED plant to enjoy a good time, but also let the LED plant for future demand over optimistic. All plants in 2009 to 2010, actively expanding production capacity in the second half of 2010, but found that the overall demand is not as good as expected. The main reason is the end product manufacturers to reduce costs, to reduce the number of pieces of LED are used as the main means; and continue to improve efficiency, brightness in product specifications under the same conditions, reduce the number of LED teeth is an inevitable trend, coupled with the global economy is poor, market growth than expected.

Therefore, LED supply and demand in the second half of 2010 began to reverse, oversupply phenomenon began to become more serious, and even with DRAM, Display and Solar were classified as 3D1S four tragic.
