Abstract
The present invention features an apparatus and method for collimating light for use with a tiled, flat-panel display having a seamless appearance (i.e., having visually imperceptible seams). A novel, multi-cell, collimation lattice is placed behind the bottom mask of the tiled, flat-panel display assembly, but in front of an illumination source. The lattice is formed from a thin, non-reflective material, so that the acceptable light passing through the lattice is not 'blocked', but the unwanted (off-axis) light impinges upon the lattice cell walls and is absorbed.
