1. A large flat panel display comprising:

  • a) a plurality of tile display modules, each tile display module having a plurality of pixels arranged in a matrix having uniformly periodic interpixel spacing, said pixels comprising an active area and an inactive, dark area, and each tile display module having electrical interconnection means for addressing the pixels such that each pixel may be selectively controlled through the electrical interconnection means, and pads for interconnecting with the electrical interconnection means; and

    b) a back plate for supporting and interconnecting the tile display modules, having at least one layer of optically opaque interconnection lines for connection to the electrical interconnection means of a plurality of the tile display modules, said at least one layer of optically opaque interconnection lines forming a light shield being disposed in said inactive, dark areas of said pixels, thereby forming a mask structure, the optically opaque interconnection lines having pads for electrical connection thereto;

    the tile display modules being mounted upon the back plate, with the pads of the tile display modules being electrically connected to the pads of the interconnection lines of the back plate, aligning the tile display modules thereon, and located such that the interpixel spacing between two adjacent pixels on two adjacent tile display modules maintains the uniform periodicity of the interpixel spacing between adjacent pixels within the tile display modules, andthe pixels of the large flat panel display being addressed via the interconnection means of the back plate as if the large flat panel display comprising a plurality of tile display modules were a single monolithic large display.
