A smelling screen is a type of digital scent technology, unveiled in 2013, that combines a display screen, similar to a television or computer monitor, with an odor emitting device capable of pinpointing the smell to a specific portion of the displayed image. It is believed to be the first device to incorporate smells into a television screen,^[1] though certainly not the first to synchronize smell with a displayed image (see Digital scent technology).
