Abstract: An information display system is provided which comprises a body of material serving as both a substrate for thin film components and a medium for the propagation of Rayleigh acoustic waves along its surface. The thin film components include elements responsive to the Rayleigh waves to provide information at selected locations on the surface of the body. These components may be either the control elements or the output elements of the display system.
