Omron believes that Spatial Projection Displays are the future for signage
Using Omron’s Spatial Projection Display (SPD) technology, images can be projected anywhere and appear to be floating in the air. Earlier space projection technologies have required a large number of distinct components and are relatively large systems requiring substantial space to install. Omron has used its light directivity and micro-fabrication technology developed through the LCD display and backlighting businesses to allow images to be projected into empty space with just one sheet of plate and a single LED. The sheets themselves are transparent, so are unobtrusive, thin and light for attaching to glass and other surfaces.
Omron is initially supporting 2D and 3D images with SPD technology. In future, it will introduce curved plexiglass panels that can be adapted to objects with shaped surfaces.
