Bezel-concealing display covers and display devices

摘要

Bezel-concealing display covers and display devices are disclosed. In one example, a bezel-concealing display cover includes a bezel and a display panel includes a perimeter portion having a first surface and a second surface such that the perimeter portion is configured to be offset from the bezel of the display device by a gap GA. The bezel-concealing display cover further includes a first array of prisms on at least one of the first surface or the second surface of the perimeter portion that extend from an edge of the perimeter portion to a distance L. Each prism of the first array of prisms has a prism angle θ, and the first array of prisms 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.

主权项

1. A bezel-concealing display cover for coupling to a display device comprising a bezel and a display panel, the bezel-concealing display cover comprising:
a perimeter portion comprising a first surface and a second surface, wherein the perimeter portion is configured to be offset from the bezel of the display device by a gap GA; a first array of prisms on at least one of the first surface or the second surface of the perimeter portion, the first array of prisms extending from an edge of the perimeter portion to a distance L, wherein:
each prism of the first array of prisms comprises a first light transiting facet, a second light transiting facet, and a prism angle θ between the first light transiting facet and the second light transiting facet, wherein the prism angle θ of the individual prisms of the first array of prisms non-linearly decreases in a direction from the edge of the perimeter portion toward a center of the bezel-concealing display cover at the distance L such that a rate of prism angle decrease at a midpoint between the edge of the perimeter portion and the distance L from the edge of the perimeter portion is greater than a rate of prism angle decrease proximate the edge of the perimeter portion and a rate of prism angle proximate the distance L from the edge of the perimeter portion;the first array of prisms 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; anda central region bounded by the perimeter portion, wherein the first array of prisms is not present at the central region.
