Two Ministries Support Display Technology Research, And Mini/Micro LED Industrialization Speeds Up Again

- Apr 01, 2021-

During the "14th Five-Year Plan" period, the High-tech Department of the Ministry of Science and Technology will further support scientific and technological research in the display field. In the national key research and development plan, the key materials, equipment and technology of Micro LED display will be jointly deployed in the fields of materials, information, and manufacturing." On March 25, Lei Peng, deputy director of the High-tech Department of the Ministry of Science and Technology, said at the first member meeting of the Mini/Micro LED Display Industry Branch of the China Electronics Video Industry Association and the Forum on the High-quality Development of the New Generation Display Industry.

After several years of hard work and accumulation, the MiniLED industry is about to enter a stage of large-scale heavy-duty. As the most anticipated ultimate display technology, Micro LED still has many technical bottlenecks that need to be resolved before commercialization, including quality inspection and repair equipment, mass transfer and joining technology, drive and backplane technology, etc.

Among them, the mass transfer technology and the efficiency and reliability of the red light Micro LED chip are the more difficult challenges in the current Micro LED production process. Specifically, these two major problems involve relatively weak links in China, such as key equipment and semiconductor materials.

At this forum, Lei Peng said frankly that although my country has become the world’s largest display panel production base, with a total investment of more than 130 million yuan in the new display industry, there are still technical bottlenecks in the development and preparation of materials and devices for Micro LED. , The massive transfer technology for industrial applications has not yet been fully satisfied, and MOCVD and other equipment are completely dependent on imports.

At the same time, He Chuanchu, director of the Finance Department of the Ministry of Industry and Information Technology, also pointed out that at present, Mini/Micro LED has become a breakthrough in emerging industries. Industrial funds, guidance funds and various social capital should be promoted to support the sustainability of the Mini/Micro LED display industry. development of.

To this end, during the "14th Five-Year Plan" period, the High-tech Department of the Ministry of Science and Technology will provide support for technological research in the display field, and expand the layout of key materials, equipment and technology and other weak links, starting with materials, manufacturing, and information. .

One is to set up key special projects for new display and strategic electronic materials in the field of materials, and lay out key materials and devices for Micro LED displays. The second is the deployment of new Micro LED and equipment technology in the manufacturing field. The third is to superbly deploy Micro LED's light display and interactive application technology in the information field to accelerate the simultaneous realization of technological breakthroughs in Micro LED equipment, materials and applications.

Looking back at the development process of the Micro LED industry in the past two years, whether it is industry-university-research cooperation, or the integration and collaboration of the upstream and downstream of the industry chain, it has promoted substantial progress in the Micro LED field, and terminal products have begun to take the stage.

For example, Konka has released the world's first Micro LED watch in 2020, becoming a leader in the application of Micro LED wearable devices. In the field of large and medium-sized displays, leading companies such as Sanan Optoelectronics, TCL, BOE, Leyard, etc. are also increasing their strategic layout, and some products have begun to be applied.

In the future, with the support of relevant policies, the industrialization of domestic Mini/Micro LEDs will be further accelerated as the collaboration effect of the industrial chain becomes more prominent and the layout of corporate intellectual property rights increases.
