Micro-LED theme report
The theme report on May 24 was even more noticed. The number of participants reached about 700, which accounted for about one-third of the total display week technical topics. The auditorium was basically filled with audiences half an hour earlier, and there were many afterwards. People stood and listened to lectures. The lecture hall was a packed event throughout the day. The content of the lecture did not disappoint the enthusiasm of the audience. It included a variety of related technologies such as growth technology, transfer technology, dead-end detection and repair, and full-color technology. The core requirements have been introduced in detail. The concept is clear and the content is rich.
On the hot Micro-LED scene, a large number of people arrived before the speech began. After the report began, there was a packed seat and the audience listened carefully.
Guests' wonderful speech, the audience seriously questioned.
Professor Liu Zhaojun of the Session Chair and Prof. Ioannis Kymissis of Co-chair presented the “Outstanding Paper Award” to Dr. Zhang Lei, CEO of JBD.
