NEC Display Solutions offers exclusively large public displays from 32 to 46 inch diagonal screen.
The solution is based on the patented Dispersive Signal Technology "from 3M, which does not restrict the display. Thus the displays are suitable as display panels, where the interaction with the viewer is desired, for example, information terminals at point of sale.
The 3M system consists of a glass bottom, which is equipped with sensors. It acts as a rugged protective glass for the panel. The sensors register the vibrations within the substrate, after contact with a finger or a pen arise. This new technology is, according to NEC, among others more resistant to dirt than previous optical or acoustic touch systems.
