he 23rd China International Optoelectronic Expo (CIOE) was grandly opened in Shenzhen International Convention and Exhibition Center on September 16. The exhibition area of CIOE China optoelectronic Expo reached 160000 square meters, with more than 3000 exhibitors and 42438 visitors on the first day, setting a new record. This is particularly prominent at the moment of the impact of the epidemic, and comprehensively demonstrated the application of optoelectronic technology in F5G, smart cars Innovative products and technologies in emerging application fields such as semiconductor chip, 3D vision, sensor, intelligent security, AR / VR, robot, smart home and camera highlight the key role and strong vitality of photoelectric technology as a strong supporting technology. At the same time, more than 70 conferences were held, including Industrial Forum (communication, optics, laser and infrared), CIOE and yole international high-end forum (lidar, silicon photons, 3D sensing), optical + Application Forum (AR / VR, 3D vision, robot, intelligent vehicle, etc.) and OGC global Optoelectronics conference, reflecting the closer integration of CIOE in academia and industry, Give full play to the leading role of new technologies in the exhibition, and accelerate the transformation and upgrading of the domestic photoelectric industry.
