Advancements in Self-Emissive MicroLED Display Technology for Augmented Reality
Qiming Li, CEO of JBD (Jade Bird Display)
Presentation Abstract
A key challenge associated with microLED displays is the decrease in wall plug efficiency as pixel size decreases, especially for red emission. This talk will analyze the efficiency droop phenomenon and introduce JBD’s innovative solution to address this bottleneck. A comprehensive comparison of various red emission technologies employed in recent years will be presented, focusing on material science and device physics perspectives.
Furthermore, the performance of JBD’s monochrome red, green, and blue panels, featuring a 0.13″ diagonal size and a 4-um-pixel pitch, will be examined. These panels are combined in an X-cube configuration, forming a polychrome projector with a resolution of 640 x 480 VGA. Additionally, the presentation will showcase the mass production status of these projectors at JBD’s Hefei fabrication facility.
Finally, the talk will provide insights into the research and development status of microLED displays with a 5-um-polychrome-pixel-pitch. This information will shed light on ongoing efforts aimed at further enhancing microLED technology in terms of pixel density and color performance.
Qiming Li, CEO, JBD (Jade Bird Display)
Qiming Li, the CEO of JBD (Jade Bird Display), holds a Ph.D. in Chemical Engineering, which he earned from the University of New Mexico in 2005. Following his graduation, Qiming Li embarked on a postdoctoral position at Sandia National Laboratory, where he subsequently became a technical member of staff. During his seven-year tenure at Sandia, he focused on the synthesis of III-nitride nanowire materials and their application in device fabrication and testing. In 2013, Qiming Li assumed the role of Chief Technology Officer (CTO) at Enraytek Optoelectronics in Shanghai, China. Two years later, in 2015, he founded JBD and has since served as the CEO and Chairman of the company. As the CEO, Qiming Li’s primary interests and efforts revolve around technology and product development, with a specific focus on the commercialization of microLED displays for augmented reality (AR) applications. Qiming Li’s passion lies in inventing groundbreaking technologies and building microdisplay products, which is evident from his extensive patent portfolio comprising over 150 patents. Under his leadership, JBD’s microLED panel samples and products have garnered significant recognition. In 2018, they received the esteemed “Best Prototype Award” from the Society of Information Display, and in 2023, JBD’s displays were honored with the prestigious “Display of the Year Award.”
