In the case of tight supply in 2014, it is expected that the decline in the average selling price of LED chips will stabilize. In 2011, the average selling price of LED chips fell by 40-50 year-on-year. In 2012, it fell by 30-40. In 2013, the decline narrowed to 15-20. This led to the erosion of the profit margin of LED chip manufacturers. However, it is expected that the downward trend of the average selling price of LDE chips will stabilize in 2014, so it is expected that the profitability of LED chip manufacturers will resume.
Thanks to a stable price environment, the profit margin of LED chip manufacturers is expected to rebound strongly in 2014. The average selling price of LED chips in 2011 and 2012 fell by 30-50% year-on-year. As the average selling price fell much faster than the cost decline, the industry's gross profit margin shrank severely. However, the 2014 gross margin trend should begin to improve rapidly. It is expected that the average selling price of LED chips will slow down to 10-15 (year-on-year), which is consistent with the rate of cost reduction.
