    Abstract: A touch system that employs interference effects is disclosed. The touch system includes first and second waveguides that have first and second optical paths that define an optical path difference. The first and second waveguides are configured so that a touch event deforms at least one of the waveguides in a manner that causes the optical path difference to change. The change in the optical path difference is detected by combining the light traveling in the two waveguides to form interfered light. The interfered light is processed to determine the occurrence of a touch event. The time-evolution of the deformation at the touch-event location can also be determined by measuring the interfered light over the duration of the touch event.

    Abstract: Curved bezel-concealing display covers and display devices are disclosed. In one embodiment, a bezel-concealing display cover for coupling to a display device having a bezel and a display panel includes a curved perimeter portion having a first surface and a second surface, wherein the curved perimeter portion is configured to be offset from the bezel of the display device by a varying gap GA. The bezel-concealing display cover further includes an array of prisms on at least one of the first surface or the second surface of the curved perimeter portion. The array of prisms extends from an edge of the curved perimeter portion to a distance L. The array of prisms and the curved perimeter portion is configured to shift a portion of an image proximate the bezel produced by the display panel such that the shifted portion of the image appears over the bezel to an observer.
