    Abstract: A touch screen system configured to detect a displacement of a cover sheet when pressure or force is applied to the cover sheet upper surface. A light source and photodetector are configured to be in optical communication by reflection of light from the light source from the lower surface of the cover sheet. A displacement of the coversheet changes the amount of reflected light that falls upon the detector. The detector signal can be used to measure the amount of displacement, as well as the time-evolution of the displacement. The touch-screen system can be interfaced with a touch-sensitive display unit to form a display system having both pressure-sensing capability and touch-sensing capability.

    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.
