Since 2014, the LED industry as a whole has shown a continuous good trend. In the second quarter, the good trend has been obviously transmitted from the LED lighting application link to the middle and upper reaches of the packaged chip field. As the penetration rate of LED lighting increases, the demand for the entire LED industry chain is strong. Recently, some LED listed companies released their semi-annual performance forecasts for 2014. According to the disclosed performance forecast, the overall performance of LED listed enterprises in the first half of the year was excellent, and the net profit of most enterprises achieved year-on-year growth, among them, the net profit attributable to shareholders of listed companies in the first half of the year, such as Huacan Optoelectronics, Lianjian Optoelectronics, zhouming technology and Jiawei, doubled year on year, up 215, 270, 113 and 176 respectively. Although the net profits of Qianzhao Optoelectronics, Ruifeng Optoelectronics, luxiao technology, maoshuo power supply, Nanda optoelectronics and other enterprises have declined to varying degrees year-on-year, they have also achieved profitability. In the performance forecast, most of the companies attribute the performance growth to the growth of the main business caused by the market recovery.
