[Text|High-tech LED reporter Xu Chaopeng] The LED industry has developed to the present day, and patents have always been a topic that cannot be avoided between enterprises and enterprises. Because in the current LED industry related research and development and production, domestic companies account for a very small proportion of invention patents, and for the phosphor field, naturally no exception.

“The domestic phosphor industry is still in the early stage of development, and the demand in the future is definitely higher and higher. And I expect that the phosphor will maintain a growth rate of 30%-40% within three years.” Liu Ronghui, director of the Rare Earth Luminescence Division 2014 High-tech LED Annual Meeting on the morning of December 13th, Liyang Optoelectronics named "Technology-driven supply chain transformation new opportunities" sub-forum said that the future concentration of LED phosphor companies will be higher and higher, but to be bigger To strengthen the brand, we must pay attention to the quality and intellectual property of the product.

In the field of patent subdivision, Liu Ronghui analyzed that aluminate phosphors, because the phosphor itself has no intellectual property problems, domestic and foreign technology and intellectual property innovation are very different, so it will be an irreplaceable product in the next few years. The silicate phosphor will be suitable for low- to medium-end backlight display, but it will eventually be replaced by β-sialon:Eu phosphor.

At the same time, due to the immaturity of the NOx phosphor, it is urgent to develop a new system phosphor with independent intellectual property rights, thus leading the development of technology with intellectual property rights and occupying the commanding heights of the market. In addition, white LED devices will also develop new combinations to meet applications in display (high efficacy, wide color gamut) and illumination (high color rendering, low color temperature).

"The tenth meeting of the Standing Committee of the 12th National People's Congress held at the end of August this year adopted a decision on the establishment of intellectual property courts in Beijing, Shanghai and Guangzhou. This shows that intellectual property rights will be more and more valued by the state in the future." Liu Ronghui mentioned.

“At the same time, the number of PCT patent applications is a globally recognized indicator for measuring the innovation capability of a country or region. In the global LED industry, the LED phosphors with the technology as the 'rules of the game', the reserves of intellectual property such as standards and patents. It will be the 'ticket' to the global market." Liu Ronghui finally mentioned.
