Abstract
A screen assembly holding mechanism is provided for multiscreen displays employing an abutted array of substantially identical display devices that each display a subdivided portion of a total image such that together they display the total image. Each display device includes a screen and a Fresnel lens that form a screen assembly. The screen assembly is connected to the display device by the screen assembly holding mechanism. The screen assembly holding mechanism provides a significantly smaller boundary between the display devices than has before been possible and does not significantly interrupt the total image. The screen assembly holding mechanism also allows for differing expansion and contraction rates of the screen and Fresnel lens and substantially lessens the likelihood of either becoming detached from the screen assembly holding mechanism. The screen assembly holding mechanism may include a safety lip that covers an outer edge of the screen for protection against injury.
