Abstract

A method for manufacturing a display includes providing a plurality of light guiding fibers or other elements extending out from a display screen. The light guiding elements are in a matrix to form a first light guiding body forming a strip along the edges of each individual display screen. The first light guiding bodies form a compensating portion of an image compensating apparatus, a cross-sectional area of each light guiding element increasing from light-collecting end (closest to the display screen) to opposite light-releasing end. The compensating portion includes a light incident surface and a light emitting surface.
