A scent-emitting video display system

We propose a new method in which scents are ejected through the display screen in the direction of a viewer, in order to enhance the reality of the visual images. A thin LED display panel filled with tiny pores was made for this experiment, and an air control system using a blower was placed behind the screen. We proved that the direction of airflow was controlled and scents properly travelled through the pores to the front side of the screen. Furthermore, we evaluated the psychological effects of visuals combined with scents.
