Sharing various technologies and case studies, such as Li-Fi to replace Wi-Fi and smart farming.
Discussion on MicroLED technology with wide applications in displays, automobiles, medical, etc.

The LED Expo, where you can see LED, OLED, and MicroLED at a glance, has opened.

The 15th LED & OLED Expo, held at KINTEX for three days from the 27th to the 29th, consists of an exhibition, an industry forum, and a forum on the development of the optical convergence industry, serving as a venue to discuss industrial competitiveness and related technologies suitable for the industrial revolution.

At the exhibition, they were introduced as leading companies in new technologies, including OLED desk lamps, quantum dot reflective lighting, BLU channel lenses, and LED security light fixtures. In addition, 350 companies participated and exhibited LED lighting, LED lighting for plant growth used in smart farms, flexible LEDs, museum curator services using Li-Fi, LED signage, etc.
The LED Industry Forum covered topics such as LED lighting certification and market trends, measures to enhance the competitiveness of the LED industry in the era of the Fourth Industrial Revolution, as well as MicroLED and displays, and the fields of the Fourth Industrial Revolution, LED, ICBM, and artificial intelligence lighting.

Choi Gyun-seok, an official from the Ministry of Trade, Industry and Energy who gave a presentation on trends in the LED industry following the Fourth Industrial Revolution, said, “It is regrettable that while domestic LEDs have maintained the world’s second-place ranking, they are falling behind in the competition for rankings due to China’s growth,” adding, “We must regain the lead in the MicroLED market through active development.”

Officer Choi stated that the goal of domestic LED R&D projects is the “development of microLEDs and new convergence technologies equipped with ultra-low power, ultra-compact, and ultra-intelligent display lighting and sensing functions,” adding that domestic researchers are developing △low-power microLED pixel technology and display panels for large screens △and for smart wearable devicesIt was announced that research is being conducted on flexible micro LED devices and modules, high-power near-infrared micro LED devices and lidar modules for autonomous driving devices, and high-density flexible micro LED devices for AR/VR.
The discussion also covered the medical field of MicroLEDs. Professor Jae-Woong Jeong of Colorado State University introduced the 'Soft Auto LED' currently under research, stating, "Using MicroLEDs, various diseases can be prevented and treated."

While conventional medical equipment is large and rigid, which can be strenuous during repeated examinations, MicroLEDs are ultra-compact and safe because they enable sensitive bio-recognition without skin incisions. Light-based applications include detecting specific neurons in the brain for treatment, removing wounds, measuring pulses, and treating and monitoring diabetes.

In addition, the forum discussed trends in micro LED chips and transfer technology, AR/VR utilizing displays, the direction of industrial development for Li-Fi using digital light, and domestic and international standard trends for IoT lighting.
