ABSTRACT:
A system for increasing the useful viewing angle in an array of video display units, also called a video wall, comprising the duplication of an outer marginal strip of the displayed image on adjacent video display units, a cylindrical lens structure mounted over the frame of each video display units and outer strip, with a spatial compression of a portion of outer strip, or the duplication of the image in an outer marginal strip of the displayed image in adjacent video display units, and a spherical lens placed over the entire viewing surface and frame of each video display unit. With proper selection of lens parameters and aforementioned image modifications, the invention produces a magnified image that obscures the image of the frame between adjacent video display units and gives the effect of a single large display over an increased viewing angle.
