Abstract
A light transfer apparatus for transferring an image from a relatively small projection surface to a relatively large display surface. The light transfer apparatus includes modules having a display surface, a light input surface and a connection surface. A plurality of modules are arranged so that their respective display surface combine to form the display screen. The modules are connected to a frame by snapping each module onto a support bar which is connected to the frame. Optical fibers, which terminate on the surface of each module and extend from the light input surface of each module, are positioned in a pigtail frame to form the projection surface. An image projected on the projection surface is viewed in magnified form on the display screen. The modular assembly design allows individual modules to be removed and replaced in the display screen without affecting any modules in addition to the replaced module.
