With the trend of LED industry improving, the gross profit margin of packaging enterprises has stabilized and rebounded. According to data survey, the output value of LED packaging and modules reached 14. 3 billion US dollars in 2015 and increased to 14. 7 billion US dollars in 2016, a growth rate of 2. 6. It is estimated that the output value in 2017 will reach 15. 3 billion US dollars, with an annual growth rate of about 5. In recent years, with the continuous improvement of LED penetration rate, packaging capacity is also accelerating its transfer to China. Chinese LED packaging manufacturers have gained a stable market position in the backlight, lighting and display markets, and it is expected that the packaging capacity in mainland China will continue to grow in 2017.

Packaging is a very important part in the production process of LED display screen. Generally speaking, the function of the package is to provide sufficient protection for the chip to prevent the chip from failing due to long-term exposure or mechanical damage in the air, so as to improve the stability of the chip. For LED packaging, it is also necessary to have good light extraction efficiency and good heat dissipation. Good packaging can enable LED to have better luminous efficiency and heat dissipation environment, thus improving the service life of LED. After experiencing rapid growth in previous years, the LED industry is gradually entering the plateau period, and the growth rate is slowing down. Although the growth rate of the industry has slowed down significantly, the regional pattern of the industry is also changing, and the packaging capacity is accelerating its transfer to China. Among them, the market share of Chinese manufacturers continues to increase and is playing an increasingly important role. LED packaging industry is mainly concentrated in China, Japan, Taiwan, the United States, Europe, South Korea and other countries and regions. From the perspective of the development of LED industry, manufacturers in Japan, the United States, Europe and other countries have become the early LED packaging industry centers relying on their first-mover advantages and technological advantages and equipment advantages. In the second stage, Taiwan and South Korea have a complete consumer electronics industry chain, with a clear division of labor in each link and a rapid rise; At present, it is in the third stage. Mainland China has undertaken industrial transfer and benefited from cost advantages and strong market demand for downstream products. It has become an important LED packaging production base in the world. The LED packaging industry has gone through the era of high gross profit and is currently maintaining normal Gross profit margin. A group of leading packaging enterprises in the domestic LED packaging market are continuously strengthening their competitive strength and expanding their scale. They are not weaker than foreign and Taiwan LED packaging enterprises in terms of domestic market competitiveness and independent intellectual property rights. As far as packaging is concerned, domestic enterprises already have the same strength as international LED enterprises. At present, there are more than 1000 packaging enterprises, and there are more than 30 enterprises with annual sales of more than 0. 1 billion yuan, and less than 10 million enterprises in the second camp with sales of between 0. 1 billion yuan and 300 yuan. accounting for about 30, the sales volume of most enterprises is less than 10 million yuan. Jiangsu Miyou Optoelectronics will continue to bring high-quality and high-performance products to new and old customers, and strive to become the leader in the packaging industry.
