Developed by a team from Tongji University, the “Ultra-lightweight Display System” reimagines in-flight entertainment by using compact projectors and gesture recognition in place of traditional seatback screens. Integrated into the Passenger Service Unit, it can project content onto tray tables, windows, or partitions - reducing system weight, saving fuel, and freeing up cabin space. With intuitive controls and PED compatibility, this innovative student-led solution offers airlines a moresustainable IFEC option and passengers a flexible, immersive experience. Among the USPs that led the judging panel to select Tongji University and its development partner Boeing as the winners were the enormous potential weightsaving when replacing seatback IFEC systems, as well as the developers’ plans to include a feature to avoid jitter in the projected image induced by turbulence.
