Enterprises in the upstream and downstream of the laser TV industry chain jointly discussed the construction, technological innovation, and development trend of the industry chain. Ge Bin, Deputy Mayor of Hefei City, attended the meeting and discussed the industry development trend with entrepreneurs.
Dong Min, deputy secretary-general of the China Electronic Video Industry Association, delivered a speech for the forum. He said that under the global economic downturn, China has completed the post-epidemic rebirth as quickly as possible, and may become the only major global player with positive growth in 2020. Economy. At present, the global display industry is undergoing unprecedented changes. Laser TV has unique advantages in the field of large screens, and the construction and improvement of the industrial chain is a key issue. Deputy Secretary-General Dong hopes that companies will have a broader perspective and be more sensitive The pace of development and more diversified services promote the development of the laser TV industry. Colleagues from upstream and downstream enterprises in the global laser TV industry chain strengthen cooperation, collaborative innovation, and unswervingly develop the laser TV industry so that more consumers can enjoy technology The intelligence and convenience brought about by progress have injected new vitality into the color TV display market.

Hefei Deputy Mayor Ge Bin delivered a speech at the forum. Deputy Mayor Ge mentioned that Hefei’s current display industry is a four-dimensional development. The hard screen represented by BOE The flexible screen represented by Visionox, as well as micro display and laser display, is currently booming in the laser display industry, and products including full-color lasers, light source modules, laser portable micro projectors, electronic screens, etc. have also been formed. The mayor hopes to gather high-quality global resources, build a more superior laser industry ecosystem, and build laser display into an important platform for the high-quality development of the display industry. He also hopes to jointly build a complete laser display industry chain.
(Ge Bin, Deputy Mayor of Hefei City) Gao Yuling, chairman of
Laser TV Industry Branch, delivered a speech in the form of video. Chairman Gao fully affirmed the work done by the Laser TV Industry Branch in the past two years, including standard formulation, market Chairman Gao pointed out that although the laser TV industry chain is still in the development stage, its industrial characteristics have the conditions for rapid growth. It can be said that the laser TV industry chain is becoming more and more perfect, and it is hoped that through the in-depth development of various enterprises Exchanges strengthen the industry, increase the growth rate, and promote the rapid development of the laser TV industry.
Zhao Degang, a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences and director of the Optoelectronics Research and Development Center, shared "Gallium Nitride-based Materials and Lasers", which mainly introduced the current status and challenges of GaN lasers. The biggest challenge comes from epitaxy, low luminous efficiency and structure Complicated, the Institute of Semiconductors of the Chinese Academy of Sciences has done a lot of work in these areas, hoping to work with the industry to break through the difficulties of GaN laser technology.
