Abstract:
One or more embodiments of the invention provide an apparatus and method for producing an image on a display screen that extends to the pixels or image elements disposed at the edge of the display screen. The display screen has an optical element with a thickness and an index of refraction that are selected to direct light to pixels or image elements disposed at the edge of the display screen without passing through the portion of the optical element that is blocked by a support frame or other structural member disposed on the rear surface of the display screen. Positioning such display screens together into a single screen assembly produces a tiled display having a much less noticeable grid pattern visible to the viewer.
